Kinetic models of swelling and thermal stability of silver/poly(vinyl alcohol)/chitosan/graphene hydrogels
(Korean Society of Industrial Engineering Chemistry, 2019)
Silver nanoparticles (AgNPs) were synthesized by in situ electrochemical reduction of Ag+ ions in poly(vinyl alcohol)/chitosan/graphene (PVA/CHI/Gr) hydrogel matrices with different concentrations of chitosan. The ...
Synthesis, structural characterization, DFT calculations and antiproliferative evaluation of novel spirohydantoin derivatives containing a substituted benzyl moiety
(Elsevier B.V., 2019)
Two series of cycloalkanespiro-5-hydantoins, namely cyclohexanespiro-5-hydantoins and cycloheptanespiro-5-hydantoins with a 4-substituted benzyl or a 2-(4-substituted phenyl)-2-oxoethyl group at N3 position, were synthesized ...
Validation of energy-dispersive X-ray fluorescence procedure for determination of major and trace elements present in the cement based composites
(Elsevier B.V., 2019)
Adjustment and subsequent validation of energy-dispersive X-ray fluorescence (ED-XRF) method for cement based binders with addition of mineral raw materials (fly ash, zeolite and bentonite) was conducted. Eighteen chemical ...
Biodegradation of poly(ε-caprolactone) (PCL) and medium chain length polyhydroxyalkanoate (mcl-PHA) using whole cells and cell free protein preparations of Pseudomonas and Streptomyces strains grown on waste cooking oil
(Elsevier Ltd, 2019)
Petrochemical plastics are generally recalcitrant to microbial degradation and accumulate in the environment. Biodegradable polymers obtained synthetically like poly(ε-caprolactone) (PCL) or polyhydroxyalkanoates (PHA), ...
The initial characteristics of the polypyrrole based aqueous rechargeable batteries with supercapattery characteristics
(Elsevier Ltd, 2019)
The electrochemically synthesized polypyrrole (PPy) is investigated as a possible active material of the low-cost aqueous based secondary power sources in combination with zinc, lead oxide, and lead sulfate. The discharge ...
Characterisation of peppermint (Mentha piperita L.) essential oil encapsulates
(Taylor and Francis Ltd, 2019)
The aim was to choose the optimal encapsulation system and to incorporate encapsulates loaded with essential oil into the ice cream as a model food product. Methods: Ca-alginate beads were produced by electrostatic extrusion ...
Functional bioreactor characterization to assess potentials of nanocomposites based on different alginate types and silver nanoparticles for use as cartilage tissue implants
(John Wiley and Sons Inc., 2019)
In this work, functional characterization of biomaterials concerning potential application as articular cartilage implants was performed by using a biomimetic bioreactor with dynamic compression in the physiological regime ...
Effects of non-thermal atmospheric plasma treatment on dentin wetting and surface free energy for application of universal adhesives
(Springer Verlag, 2019)
The study aims to evaluate the effects of non-thermal atmospheric plasma (NTAP) treatments on dentin wetting and surface free energy (SFE) and compare the effects of NTAP treatment, etch-and-rinse, and self-etch protocols ...
Selection of the suitable polymer for supercritical fluid assisted preparation of carvedilol solid dispersions
(Elsevier B.V., 2019)
Solid dispersions production is one of the substantial approaches for improvement of poor drug solubility. Additionally, supercritical fluid assisted method for preparation of solid dispersions can offer many advantages ...
Electrochemical synthesis and characterization of poly(o-toluidine) as high energy storage material
(Elsevier Ltd, 2019)
Poly(o-toluidine) (POT) is electrochemically synthesized on graphite electrode at constant current density of 1.5 mA cm−2 from aqueous electrolyte of 1.0 mol dm−3 H2SO4 and 0.25 mol dm−3 o-toluidine. Electrochemical ...
