AB  - The surfaces of natural (NZ) and zeolite/iron oxyhydroxide composite (ZFe) samples were analysed by means of inverse gas chromatography (IGC) using the adsorption data of organic non-polar and polar probes, in the infinite and finite-dilution regimes, in the temperature range 483-513 K. The dispersive components of the free energy of adsorption, γS, determined by the Gray method, decreased with increasing temperature for both zeolites. The specific interactions were characterised by the specific free adsorption energy change, ΔGaS, the specific enthalpy change of adsorption, ΔHaS, as well as the donor and acceptor interaction parameters (KA, KD) and the basic character of the NZ and ZFe was evidenced. The adsorption isotherms of n-hexane, benzene, chloroform and tetrahydrofuran (THF) were determined under finite surface coverage and used to estimate the specific surface area and the adsorption energy distribution. The adsorption capacity of the ZFe was higher than for NZ for all the investigated adsorbates. The specific surface areas and pore size distributions were also determined using nitrogen adsorption-desorption isotherms, i.e., the BET method. It was observed that the nature of the adsorbate and the properties of the solid surface of the initial and modified samples governed the uptake of adsorbates.

AB  - Kaolinite/illite (KUb) and sepiolite (SEP) clays were used to study Cr(III) adsorption removal from aqueous solutions so that they could be utilized after saturation for ceramic manufacturing. SEP had a larger specific surface area and a higher PZC than KUb. The removal of Cr(III) was evaluated using a batch equilibration procedure at pHi = 4 and pHi = 6. Fast removal kinetics were observed for both clays. Maximum removal capacity was determined by changing the concentration of Cr(III) while keeping the concentration of clay constant and by altering the amount of clay while keeping the concentration of Cr(III) constant. In all situations, SEP had greater capacity than KUb, and capacity was greater for both clays at higher pHi. Not only did the pHi impact the removal capacity and efficiency, but so did the pH during adsorption and the initial concentration of Cr(III). Because of the higher PZC, the pHf for SEP was higher for the same pHi. The higher the pH and Cr(III) concentration, the higher the probability of Cr(OH)3 precipitation and the higher the removal capacity. Dried saturated clays were uniaxially pressed and sintered at 1000 °C for 2 h. The densities of the sintered materials were nearly identical to those of pure clay-based materials, but the compressive strengths were higher, which is significant for the use of saturated clays as raw materials in ceramic manufacturing. Leaching of Cr from SEP-based material was significantly higher than from KUb-based material probably due to the presence of CaCO3 in the SEP.

AB  - The sepiolite/ZrO2 composites were prepared by sepiolite (Sep) modification with zirconium propoxide in toluene at room temperature for 24 h (Sep–ZrI) or 95 °C for 4 h (sample Sep–ZrII). The efficiency of the obtained composites for the removal of phosphate from aqueous solutions at initial pH = 4 and pH = 8 was investigated. Characterization of the samples shows that synthesis at a higher temperature for a shorter time provides a slightly higher content of amorphous Zr phase, which is deposited on the sepiolite fibers as a thin layer and agglomerated nanoparticles. Compared to Sep, the composites have a lower point of zero charge and higher specific surface area and pore volume. The adsorption kinetics follow the pseudo second-order model. The adsorption capacities of the composites are approximately the same at both initial pH and higher at initial pH = 4 than at pH = 8. The XPS and ATR-FTIR of Sep–ZrI before and after adsorption identifies the formation of inner-sphere complexes as the mechanism of phosphate adsorption. The slow release during desorption with NaOH solution confirms the strong bonds of the phosphates with the surface of the composites.

AB  - The development of metal oxide-based electron transport layers in perovskite solar cells (PSCs) is being intensively researched to achieve highly efficient PSCs. They offer the advantage of higher charge carrier mobility and stability compared to typical organic materials. To reduce the recombination of charge carriers, methylammonium lead bromide (MAPbBr3) perovskite was coupled with vertically aligned TiO2 nanorods (NRs) as an electron transport layer in this study. The TiO2 NRs were grown on commercial FTO glass in hydrothermal conditions. Titanium (IV) isopropoxide (TTIP) was added in drops, slowly, in the diluted solution of HCl. The obtained precursor solution was transferred into a Teflon-lined stainless steel autoclave which contained FTO substrates and heated at 150 °C for 2 h. Then, the substrates were cleaned using DI water and ethanol and annealed at 500 °C for 30 min. The solution of MAPbBr3 in dimethylformamide (DMF) was deposited on TiO2 NRs by spin coating technique. FESEM results showed that TiO2 NRs were porous and oriented vertically upwards to the substrate and that the perovskite material filled the space between TiO2 NRs. Diffuse reflectance spectroscopy measurement of the sample proved that the absorption edge of the prepared TiO2 NRs/MAPbBr3 was extended into the visible range. By measuring the I-V characteristics of the sample in the dark and under visible light, a hysteresis curve was obtained. Prepared TiO2 NRs/MAPbBr3 photodiode will be the basis for the construction of solar cells.

AB  - The restoration of large bone defects caused by trauma, tumor resection, or infection is a major clinical problem in orthopedics and dentistry because postoperative infections, corrosion, and limited osteointegration of metal implants can lead to loosening of the implant. The aim of this study was to improve the surface properties of a 3D-printed (electron beam melting) Ti6Al4V-based macroporous scaffold by multilayer coating with bioactive silicate glasses (BAGs) and hydroxyapatite doped with a silver (AgHAP) or AgHAP additionally sonochemically modified with ZnO (ZnO-AgHAP). The coated scaffolds AgHAP_BAGs_Ti and ZnO-AgHAP_BAGs_Ti enhanced cytocompatibility in L929 and MRC5 cell lines and expressed bioactivity in simulated body fluid. A lower release of vanadium ions in coated samples compared to bare Ti scaffold indicates decreased dissolution of Ti alloy in coated samples. The coated samples reduced growth ofEscherichia coliandStaphylococcus aureusfor 4-6 orders of magnitude. Therefore, the 3D-printed Ti-based scaffolds coated with BAGs and (ZnO-)AgHAP have great potential for application as a multifunctional implant with antibacterial properties for the restoration of defects in load-bearing bones.

AB  - Effects of Na2SO4, Na2CO3, and Na2SiO3 on setting time, compressive strength (up to 90 days), and hydration mechanism of binders with high volume (70 wt%, HVFA binders) of fly ash (FA) were investigated. Before chemical activation, FA was mechanically activated. Effects of the activators on hydration process were examined by isothermal calorimetry, X-ray diffraction and thermogravimetric analyses, and scanning electron microscopy. Pore solution analyses were also performed. It was found that, with addition of the chemical activators, Portland cement (PC) hydration was accelerated and the pozzolanic reaction started earlier, which resulted in shortening of setting time and increase in early compressive strength of the HVFA binders. Combination of mechanical activation of FA and the chemical activation by sodium silicate proved to be the best choice for synthesis of HVFA binder with good physicomechanical properties.

AB  - Dicalcium phosphate (DP) materials, of which brushite and monetite were the most known, have
been intensively studied for several decades because of excellent resorptive and osteoconductive
properties that can satisfy the requirements needed for various medical applications, such as bone
cements, coatings of metallic implants and bone grafts [1,2]. Brushite and monetite are the dihydrated (CaHPO4·2H2O) and anhydrous (CaHPO4) forms of DPs, respectively, which showed much
better resorption due to higher solubility in comparison to the hydroxyapatite (HAp) and tricalcium
phosphate (TCP) [2].
In this study, the effect of different post-synthesis treatments on composition and morphology of four
brushite/monetite powders, were analyzed. All the powders have been prepared by modified
precipitation method described previously [3] with molar ratio of starting reagents (NH4)2HPO4 and
Ca(NO3)2·4H2O being 7:10. After filtering, powder I was obtained by drying the precipitate at 105
°C for 4 h, while powder II was obtained by precipitate freezing at ‒10 °C for 72 h, followed by
drying at room temperature for 72 h. By drying the precipitate at 110 °C for 24 h and 105 °C for 3 h,
powders III and IV were obtained, respectively. X-ray powder diffraction (XRPD) revealed that all
the powders are two-phase systems consisting of brushite and monetite: 98.8 mas.% brushite and 1.2
mas.% of monetite in I, 97.7 mas.% brushite and 2.3 mas.% of monetite in II, 66.7 mas.% brushite
and 33.3 mas.% of monetite in III and 45.9 mas.% brushite and 54.1 mas.% of monetite in IV. Field
Emission Scanning Electron Microscopy (FESEM, Figure 1) showed that particles of prepared
materials form the agglomerates in the form of triangular plates. In addition, materials were analyzed
for their spectral, thermal and textural properties.

AB  - During last decades, layered double hydroxides ([MII1−xMIIIx(OH)2]x+(A−)x/n·yH2O, LDHs) have been used in catalysis, ceramics as well as in removal of anionic pollutants. Due to their excellent anion exchange capacity, good biocompatibility and low toxicity, the nanoparticles of LDHs showed an excellent potential as drug carriers. Nifuroxazide (C12H9N3O5, NFX) is a broad-spectrum antibacterial drug, poorly soluble in water. Towards to increase the solubility of NFX, Zn-Al-LDH/NFX composite has been prepared by precipitation method at room temperture. Zn-Al-LDH, NFX and the obtained composite were analyzed by Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), simultaneous thermogravimetry-differential thermal analysis (TG-DTA) and Brunauer–Emmett–Teller (BET) method. Characterization of the raw materials and the obtained composite confirmed the intercalation of NFX in Zn-Al-LDH. The in vitro study of drug release in simulated stomach acid and intestinal fluid showed constant release of NFX from Zn-Al-LDH during 24 h, confirming Zn-Al-LDH is a promising drug carrier.

AB  - Ciprofloxacin (CIP) as a broad-spectrum quinolone antibiotic is extensively used in daily life and can be detected in municipal and pharmaceutical wastewaters, as well as natural waters. In this study, natural mineral sepiolite (SEP), SEP modified with hexadecyltrimethylammonium-bromide (HDAB) and SEP composites with graphene oxide (GO) were used as adsorbents for the removal of CIP from aqueous solutions. The composites were prepared at a mass ratio SEP to GO of 2 : 1, using SEP and SEP modified by [3-(2-aminoethylamino)propyl]trimethoxy-silane (APT). Thermogravimetric analysis, X-ray diffraction and nitrogen adsorption-desorption were used to characterize the obtained adsorbents. The adsorption of CIP was investigated at the pH value close to pH of natural waters. The concentration of CIP in aqueous solution was determined by UV-Vis spectroscopy. GO showed the highest adsorption capacity (~ 150 mg/g). The capacity of SEP was about 60 mg/g, while the SEP modification with HDAB has led to a decrease in the adsorption capacity (~ 35 mg/g). The composite SEP/GO showed the higher adsorption capacity (~ 110 mg/g) than the composite SEP-APT/GO (~ 40 mg/g). The capacity of the composite SEP/GO was higher than of mixture of SEP and GO, which indicated a certain degree of GO exfoliation and intecalation of sepiolie particles, as it was shown by X-ray diffraction. Equilibrium data for all adsorbents, except for HDAB modified sepiolite, fitted well to the Langmuir isotherm model.

AB  - Hydrogels are three-dimensional hydrophilic networks of polymers capable of retaining large
amounts of water or biological fluids, which makes them attractive for biomedical and
pharmaceutical applications. Although various types of polymers have been investigated as
hydrogels for biomedical purposes, those obtained from natural polymers have intrinsic
advantages as they are abundant, cheap, biocompatible and biodegradable. Gelatin is a natural
polymer that has been applied in biomedicine due to its low price, biocompatibility, and
biodegradability. HPMC, a derivative of cellulose, is a hydrophilic, biodegradable, and
biocompatible polymer. However, natural polymer-based hydrogels have low mechanical
properties and are relatively soluble in physiological conditions, which requires creative crosslinking strategies to improve the functionality of the hydrogels. The citric acid (CA) is an
inexpensive and non-toxic compound that has been proven to be an effective crosslinker for
natural polymers. In addition, the incorporation of bioactive calcium phosphate particles could
further improve mechanical properties and add new functionalities to the hydrogels.
In this work, we present novel composite hydrogels for biomedical applications, based on CAcrosslinked gelatin/HPMC (HPMC-G) matrix and Mg-doped biphasic calcium phosphate filler
(BCP). Firstly, the HPMC-G hydrogels crosslinking conditions were optimized. Different CA
concentrations, curing temperatures (140-180°C) and times (3-9 min) were applied. During the
second step, the optimaly crosslinked HPMC-G hydrogel was incorporated with different amounts
of BCP. BCP was obtained by calcination of Mg-doped hydroxyapatite (HA) powder synthesized
by the hydrothermal method. XRD analysis confirmed that powder was constituted only of HA
and beta-tricalcium phosphate. The obtained composite hydrogels were characterized by
mechanical testing, FTIR, SEM, swelling behavior and drug deliverability.

properties and are relatively soluble in physiological conditions, which requires creative crosslinking strategies to improve the functionality of the hydrogels. The citric acid (CA) is an
inexpensive and non-toxic compound that has been proven to be an effective crosslinker for
natural polymers. In addition, the incorporation of bioactive calcium phosphate particles could
further improve mechanical properties and add new functionalities to the hydrogels.
In this work, we present novel composite hydrogels for biomedical applications, based on CAcrosslinked gelatin/HPMC (HPMC-G) matrix and Mg-doped biphasic calcium phosphate filler
(BCP). Firstly, the HPMC-G hydrogels crosslinking conditions were optimized. Different CA
concentrations, curing temperatures (140-180°C) and times (3-9 min) were applied. During the
second step, the optimaly crosslinked HPMC-G hydrogel was incorporated with different amounts
of BCP. BCP was obtained by calcination of Mg-doped hydroxyapatite (HA) powder synthesized
by the hydrothermal method. XRD analysis confirmed that powder was constituted only of HA
and beta-tricalcium phosphate. The obtained composite hydrogels were characterized by
mechanical testing, FTIR, SEM, swelling behavior and drug deliverability.",

AB  - The aim of this study was to investigate the influence of binary Sr, Mg ion-doping compared to the single-ion doping effects on the phase composition and morphology of hydrothermally obtained calcium hydroxyapatite (HAP) powders and on the phase composition, microstructure, and mechanical properties of the sintered materials. Additionally, the focus of this study was to investigate the possible utilization of the binary doped Sr,Mg-HAP compacts as dentin substitutes in restorative dentistry by evaluating their bonding ability with commercially available restorative materials using the shear bond strength test (SBS). The hydrothermally obtained mono-doped Mg5 and Sr5 showed the monophasic apatite structure, while in all co-doped samples β-TCP phase was formed, resulting in biphasic calcium phosphate (BCP) powders. It was confirmed that co-doping with Sr and Mg ions led to the thermal stabilization of the β-TCP phase by suppressing the phase transition into α-TCP when sintered at 1200 °C. Moreover, the co-presence of Mg ions significantly improved the hardness of Sr-doped HAP from 3.74 to 5.02 GPa. Sr,Mg-HAP dental inserts were found to achieve sufficient bonding (13.53 MPa) through the micromechanical interlocking with Z250 dental composite and Single Bond Universal dental adhesive applied with a total etch approach. The SBS values obtained for the SrMg-HAP insert were similar to the literature data on bonding ability with human dentin, indicating that binary doped Sr,Mg-HAP ceramics present a promising material for application in restorative dentistry as dentin substitutes.

AB  - Supercritical carbon dioxide (sCO2) is an ideal low-temperature cosolvent for perovskite
deposition due to its relatively low critical point (31.2 °C, 73.8 bar), no surface tension, liquidlike density, gas-like viscosity, and diffusivity. It enables faster mass transfer which allows
penetration of crystals in nanoporous structure. The study investigates the influence of time of
deposition of perovskite assisted with supercritical carbon dioxide on the filling of nanotubes.
Perovskite solar cell technology has been developed so fast due to several factors including a
tunable band gap, high absorption coefficient, and low-cost fabrication. The quality of the
perovskite film is important for the high efficiency of perovskite solar cells. Perovskite precursors
are usually deposited from the solution onto a substrate using spin-coating followed by postdeposition treatments, but often it results in low-quality films that cannot provide good
photovoltaic performances. Deposition of perovskite in the presence of sCO2 is a promising
method for the formation of high-quality perovskite layers. In this work, methylammonium lead
bromide perovskite (MAPbBr3) was deposited on TiO2 nanotubes from the solution in
dimethylformamide (DMF) by application of sCO2 at 35 °C and 200 bar for 1 h, and 3 h. FESEM
results show that TiO2 nanotubes were filled with perovskite material in both cases. The diffuse
reflectance spectroscopy measurement of samples proved that the absorption edge of prepared
TiO2 nanotubes/MAPbBr3 was extended to the visible range. Measurement of I-V characteristics
showed that the sample made for 3 h had a higher value of current than the sample prepared for 1
h. The application of sCO2 during the deposition of perovskite has enabled the preparation of a
photodiode with a better contact between TiO2 nanotubes and perovskite which is important for
the future development of solar cells.

AB  - Tooth caries presents one of the most common diseases worldwide, and its treatment involves
removal of the decayed tooth structure, and the cavity restoration using restorative dental materials. Resin based composites (RBCs) are the most commonly used restorative material in practice owing to their great aesthetic appearance allowing the clinicians to adapt the nuance of the restoration to the patient’s tooth color. However, the RBCs harden by the polymerization of monomers that leads to the polymerization shrinkage of the restoration, leaving the micro-gaps at the teeth-restorations interface which allows the secondary caries formation.

AB  - Hydrogels are promising materials for biomedical applications due to highly hydrated, porous, permeable structure with possibility to accommodate living cells, drugs, or bioactive factors. In this paper, we reported poly(methacrylic acid) (PMAA)/gelatin IPN hydrogels, synthesized by free-radical polymerization, with adjustable mechanical, structural, physicochemical, and biological characteristics. The influence of methacrylic acid (MAA), gelatin, and cross-linker in the precursor solution on hydrogels properties was investigated. The increasing concentration of MAA, gelatin, and cross-linker led to better mechanical properties, lower porosity, and water content. The compressive mechanical properties of hydrogels were significantly better in comparison to a single-network PMAA hydrogel, while the obtained compressive strength values up to 16 MPa were comparable with tough hydrogels. The increasing concentration of MAA and cross-linker reduced fatigue resistance and degradability, while the increase in gelatin content acted in the opposite way. Swelling tests in different pH conditions demonstrated strong pH-sensibility of the hydrogels, which was more pronounced as MAA concentration was higher, and gelatin and cross-linker concentrations were lower. In addition, the hydrogels strongly promoted the proliferation of human periodontal ligament stem cells and MRC-5 cells as assayed by MTT assay.

AB  - α-Tricalcium phosphate/fluorapatite (α-TCP/FAp) mixed powders were prepared in order to obtain dental root canal filling cements. Different liquids for cement pastes have been investigated and the most suitable one for obtaining rheologically optimal pastes was chosen for further analysis. Morphological changes in the cement materials as a consequence of the formation of hydroxyapatite (HAp) after the immersion in a simulated body fluid (SBF), an influence on the cell viability, and final success of the filling were investigated by field emission scanning electron microscopy. Treatment of the α-TCP/FAp mixtures in SBF at 37 °C resulted in a complete transformation of α-TCP into HAp after 10 days, while the exposure of MRC-5 human and L929 animal fibroblast cells to the cement showed complete absence of cytotoxicity. The root canal of an extracted tooth was filled with the α-TCP/FAp cement containing 5 wt.% of FAp and relatively strong adhesion between the cement and dentine was observed after 48 h. The same cement material was immersed during 10 days in SBF and after that both human and animal fibroblast cells during in vitro MTT tests showed higher cell viability compared to the control sample. These findings lead to a conclusion that the α-TCP/FAp based cement demonstrates potential for further development towards dental cement application.

AB  - Anodization was used to obtain a nanotubular TiO2 photoanode on F-SnO2 glass. Subsequent annealing in the CH4 atmosphere promoted the C-doping and improved the crystallinity of the TiO2 nanotubes. The pulsed laser deposition was applied to cover the nanotubes with Bi2O3, serving as a hole transport material. X-ray photoelectron spectroscopy analyses of the doped samples reveal a shift in the valence band's maximum position towards lower binding energy as compared to those observed for the undoped samples (annealed in the air). The doping positively affects the absorption by shifting the absorption edge to 567 nm. I-V measurements under illumination show that the C-doping of TiO2 increases the current density following the absorbance results. The highest open circuit voltage was reached for the samples with the 300 degrees C-deposited Bi2O3 layer, pointing to better quality of the p-n junction, hence of the contact between Bi2O3 and TiO2. This in situ annealing provided the formation of close contact between Bi2O3 and TiO2, which enabled a faster charge transport as compared to the contact obtained with no annealing or even with post annealing.

AB  - In this paper, the influence of cobalt loading in pillared clay-supported cobalt materials on their electrocatalytic performance toward glucose oxidation was investigated. A series of aluminum-pillared montmorillonite clay (AP) materials with different cobalt loadings (x%CoAP, x = 1, 3, 5, and 10 wt%) was synthesized using the incipient wetness impregnation method. The X-ray powder diffraction (XRPD), inductively coupled plasma optical emission spectroscopy (ICP-OES), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy coupled with energy dispersive X-ray spectrometry (FE-SEM/EDX), high resolution transmission electron microscopy (HR-TEM) coupled with EDX, X-ray photoelectron spectroscopy (XPS), and low temperature N2 physisorption, were employed for characterization of the materials. The incorporation of cobalt in porous structure of pillared montmorillonite was confirmed. The synthesized materials (x%CoAP) were used for modification of carbon paste (CP) electrode and tested in reaction of glucose electrooxidation. The electrochemical measurements were conducted using cyclic voltammetry and chronoamperometry in a 1 M NaOH solution, with or without glucose. The results showed that the increase of cobalt loading improved the electrode performance toward glucose. The highest current response and sensitivity were obtained for the CP-5%CoAP electrode. A lower electrode performance of CP-10%CoAP was correlated with the presence of higher quantities of Co3O4 (confirmed by XRPD and XPS) in the electrode material. The mechanism and kinetics of glucose electrooxidation was studied in more details for the best performing electrode (CP-5%CoAP). It was found that the process was diffusion-controlled and the diffusion coefficient was determined. The charge transfer coefficient and catalytic rate constant were calculated. The electrode exhibited satisfactory repeatability, reproducibility, stability, and selectivity. The obtained results showed that appropriate amount of cobalt loading in pillared clay led to the obtainment of non-enzymatic electrode materials suitable for sustainable and green glucose sensors.

AB  - Organic-inorganic perovskites have attracted much attention from researchers due to their high absorption in the visible part of the spectrum and low-cost fabrication. After absorption of the light, electron-hole pairs are formed. To separate electron-hole pairs and reduce recombination, perovskite is combined with TiO2 which has as a consequence, a spontaneous transition of electrons from perovskite to TiO2. This research aims to increase the contact surface of perovskite and TiO2 nanotubes by filling the nanotubes with perovskite material. The solution of methylammonium lead bromide perovskite (CH3NH3PbBr3) in dimethylformamide (DMF) was deposited on anodically synthesized TiO2 nanotubes by the high vacuum system and inert gas. The procedure involved degassation of the sample under high vacuum for 3 h at 200 °C, cooling of the sample, and putting the solution of CH3NH3PbBr3 in DMF, after which it was treated with inert gas (N2), as an overpressure which enabled the filling of the nanotubes with perovskite material. The diffuse reflectance spectroscopy measurement of the sample proved that deposition of CH3NH3PbBr3 improves the absorption properties of TiO2 nanotubes. The I-V characteristics of the sample showed photodiode behavior and characteristic hysteresis curve for perovskite material. The value of current under visible light for the sample without preconditioning was 46 mA, while after preconditioning value of current was 76 mA. The results indicate that a perovskite photodiode with increased contact between TiO2 and perovskite was made, which is the basis for future solar cell construction.

AB  - The synergistic effect of two materials is a desirable phenomenon when designing a conjugate
material. Synthetic Hydroxyapatite (HAp, Ca10(PO4)6(OH)2) is very similar to the inorganic part of
bones and teeth of mammals. It is a well-known biomaterial with good biocompatibility,
osteoconductivity and bioactivity. Nifuroxazide (NFX, C12H9N3O5) is a broad-spectrum antibacterial
drug and poorly soluble in water. Nano HAp and NFX were mixed and homogenized in rotovapor
giving as a result HAp/NFX conjugate. All materials were analyzed by Fourier transform infrared
spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM), X-Ray diffraction
(XRD), Thermogravimetry (TG) and Brunauer–Emmett–Teller (BET) method. The in vitro
antibacterial activities of HAp, NFX and HAp/NFX were examined against Gram-positive bacteria
Staphylococcus aureus, Gram-negative bacteria Escherichia coli and yeast Candida albicans. In vitro
drug release in simulated stomach acid and intestinal fluid showed a much faster release of NFX from
HAp surface than those of raw drug. Afore mentioned analyses showed the unique properties of the
HAp/NFX conjugate and introduced it as particularly prominent drug carrier.

AB  - The alkali treated subglebal tissue of the mosaic puffball (Handkea utriformis) (Sa) and Sa modified with hydroxyapatite (Sa-HAp), obtained by successive ionic layer adsorption and reaction (SILAR) method, were used for the removal of Pb2+, Cd2+ and Ni2+ from aqueous solution. The materials were characterized by FT-IR, Raman, SEM and EDS analysis and by determination of pH(PZC). The adsorption performances of Sa and SaHAp were assessed in batch experiments at different pH, contact times, temperatures and mass of the adsorbent. Different models of adsorption isotherms were used, and the best fit was obtained with the Langmuir model. Maximum adsorption capacities of Sa towards Pb2+, Cd2+ and Ni2+ were 44.82, 15.54 and 17.21 mg g(-1), while for Sa-HAp were 79.55, 52.59 and 45.01 mg g(-1), respectively. Kinetic data were well fitted by a pseudo second-order model, while thermodynamic studies disclose spontaneous and endothermic adsorption process. The Sa-Hap was successfully regenerated with 1 M NaCl and after the fifth desorption cycle and 10 h achieved 82.9, 69.7 and 60.4 %, while for 0.5 M NaCl + 0.5 M NaOH and 1 h was 78.3, 64.1, 57.5 % of desorbed Pb2+, Cd2+ and Ni2+, respectively. The competitive study and results from a column system confirmed good applicability of Sa-HAp adsorbent.

AB  - The wide use of antibiotics, the increase in chemical industry and traffic, as well as the medical industry resulted in formation of wastewater, which contains complexes of heavy metals and antibiotics. Earlier researches have shown that clay minerals had a significant large adsorption capacity for heavy metal ions, and recently examinations are focused on investigation of the possibility of treatment of water with presence of antibiotics and heavy metal ions. In this paper, the possibility of application of natural mineral sepolite for simultaneous removal of antibiotics of ciprofloxacin and copper ions from aqueous solutions. It was shown that at the initial pH of 6,0±0,1 presence of the copper ions (~ 20 mg/dm3) increased the adsorption capacity of ciprofloxacin onto sepiolite, while the presence of ciprofloxacin, had no significant influence on the removal capacity of Cu2+ ions. The results of adsorption isotherms indicated significant adsorption capacity for both, ciprofloxacin and Cu2+ ions, ie. it was shown that natural mineral sepiolite was very effective adsorbent for the simultaneous removal of ciprofloxacin and Cu2+ ions as a significant water pollutants.
