SFE as a superior technique for isolation of extracts with strong antibacterial activities from lichen Usnea barbata L.
(Elsevier Science Bv, Amsterdam, 2012)
The number of cases of fatal infections in humans and animals caused by multiresistant and panresistant bacterial strains has been dramatically increased over the past 10 years on almost every continent. Therefore, ...
Development and characterization of thermosensitive hydrogels based on poly(N-isopropylacrylamide) and calcium alginate
(Wiley, Hoboken, 2012)
This work refers to the synthesis and characterization of thermosensitive hydrogels based on interpenetrating polymer networks (IPNs) of poly(N-isopropylacrylamide) (PNIPAAm) and calcium alginate in the form of films. The ...
Modification of PET and PA fabrics with alginate and copper oxides nanoparticles
(Composite Interfaces, 2021)
The aim of this study was to fabricate novel antimicrobial nanocomposite materials by in-situ syntheses of Cu-based nanoparticles on PET and PA fabrics. The synthesis comprised three steps: (i) modification of PET and PA ...
Multivariate evaluation of the correlation between retention data and molecular descriptors of antiepileptic hydantoin analogs
(Wiley-Blackwell, Malden, 2012)
Molecular properties relevant to pharmacokinetics of two sets of newly synthesized hydantoin derivatives based on two well-known drugs (Nirvanol and Phenytoin) were studied. Properties under consideration were either ...
Micro-environmentally restricted hybridoma cell growth within polysaccharide hydrogel microbeads
(IOS Press, Amsterdam, 2013)
The mechanism of micro-environmentally restricted hybridoma cell growth caused by action of local mechanical compression stress generated within various polysaccharide hydrogel matrixes is estimated by comparing the growth ...
Substituent and solvent effects on intramolecular charge transfer of 5-arylidene-2,4-thiazolidinediones
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The absorption spectra of twelve 5-arylidene-2,4-thiazolidinediones were recorded in twenty one solvents in the range from 300 to 600 nm. The effect of specific and non-specific solvent-solute interactions on the absorption ...
The kinetics of the hydrogen oxidation reaction on WC/Pt catalyst with low content of Pt nano-particles
(Elsevier Science Sa, Lausanne, 2012)
The catalytic activity of WC/Pt electrocatalysts towards hydrogen oxidation reaction (HOR) in acid solution was studied. Tungsten carbide (WC) prepared by polycondensation of resorcinol and formaldehyde in the presence of ...
Generalized point interaction and tunneling times
(World Scientific Publ Co Pte Ltd, Singapore, 2012)
The scattering properties of four-parameter one-dimensional point interactions also define time aspect of these interactions. In this paper we investigate how different families of point interactions affect the relevant ...
Bound states in continuum generated by point interaction and supersymmetric quantum mechanics
(World Scientific Publ Co Pte Ltd, Singapore, 2012)
Four-parameter family of point interactions represent all possible self-adjoint extensions of kinetic energy operator. We demonstrate a method for generating a bound state in the continuum of point interactions which relies ...
Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...
