Tetragonal CoMn2O4 nanocrystals on electrospun carbon fibers as high-performance battery-type supercapacitor electrode materials
(Royal Society of Chemistry, 2021)
We herein report a simple two-step procedure for fabricating tetragonal CoMn2O4 spinel nanocrystals on carbon fibers. The battery-type behavior of these composite fibers arises from the redox activity of CoMn2O4 in an ...
Supercritical impregnation of cellulose acetate with thymol
(Elsevier Science Bv, Amsterdam, 2015)
Present work was aimed to investigate supercritical solvent impregnation of thymol into cellulose acetate in order to explore the possibility of developing a new functionalized solvent-free material with antimicrobial ...
Structure and magnetic properties of electrodeposited Ni87.3Fe11.3W1.4 alloy
(Elsevier, Amsterdam, 2014)
A dark gray nanostructured coating of an alloy composed of 87.3 wt.% Ni, 11.3 wt.% Fe and 1.4 wt.% W (Ni87.3Fe11.3W1.4) was electrodeposited from an ammonia citrate bath on a titanium cathode at a current density of 500 ...
Efficient multistep arsenate removal onto magnetite modified fly ash
(Academic Press Ltd- Elsevier Science Ltd, London, 2018)
The modification of the fly ash (FA) by magnetite (M) was performed to obtain FAM adsorbent with improved adsorption efficiency for arsenate removal from water. The novel low cost adsorbents are characterized by liquid ...
Impregnation of cotton fabric with pyrethrum extract in supercritical carbon dioxide
(Elsevier Science Bv, Amsterdam, 2017)
This study discusses a possibility of cotton fabric impregnation with pyrethrum extract as a tick repellent in supercritical carbon dioxide. A solubility of pyrethrum extract in supercritical carbon dioxide has been ...
Ex-situ sensitization of ordered TiO2 nanotubes with CdS quantum dots
(Elsevier Sci Ltd, Oxford, 2015)
Ordered titania nanotubes (pore diameter approximate to 90 nm and wall thickness approximate to 10 nm) were obtained by the anodization technique and used for the ex-situ deposition of cadmium sulfide quantum dots (CdS ...
Unique effects of microwave heating on polymerization kinetics of poly(methyl methacrylate) composites
(Elsevier Science Sa, Lausanne, 2013)
The effects of heating mode (conventional and microwave) on the kinetics of isothermal polymerization of MMA composite materials were investigated. Isothermal kinetics curves at temperature range from 343 K to 363 K for ...
PVA Cryogel as model hydrogel for iontophoretic transdermal drug delivery investigations. Comparison with PAA/PVA and PAA/PVP interpenetrating networks
(Elsevier, Amsterdam, 2019)
The use of polyvinyl alcohol (PVA) cryogel as a model hydrogel for iontophoretic transdermal investigations is proposed. Due to the excellent combination of its properties, it could be used for evaluating iontophoretic ...
Removal of model cationic dye by adsorption onto poly(methacrylic acid)/zeolite hydrogel composites: Kinetics, equilibrium study and image analysis
(Elsevier, Amsterdam, 2014)
Composites based on poly(methacrylic acid) (PMAA) and two types of zeolite, hydrophilic zeolite A and hydrophobic zeolite ZSM-5, were synthesized. The obtained hydrogel composites that combine well the strong interaction ...
Towards understanding intermolecular interactions in hydantoin derivatives: the case of cycloalkane-5-spirohydantoins tethered with a halogenated benzyl moiety
(Royal Society of Chemistry, 2017)
A series of cycloalkane-5-spirohydantoins bearing a halogeno substituted benzyl group (X = Cl and Br) in position 3 has been synthesized and their structures (1-6) have been determined by a single crystal X-ray diffraction ...
