Supercritical CO2 - assisted production of PLA and PLGA foams for controlled thymol release
(Elsevier Science Bv, Amsterdam, 2019)
Amorphous, medical grade poly(D,L-lactic acid) (PLA) and poly(D,L-lactic-co-glycolic acid) (PLGA) were used to develop systems for controlled release of a natural bioactive substance - thymol. Supercritical carbon dioxide ...
Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
Kinetic models of swelling and thermal stability of silver/poly(vinyl Check far alcohol)/chitosan/graphene hydrogels
(Elsevier Science Inc, New York, 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 ...
Broad Spectrum of Antimicrobial Activity of Cotton Fabric Modified with Oxalic Acid and CuO/Cu2O Nanoparticles
(Korean Fiber Soc, Seoul, 2019)
This study discusses the possibility of fabrication of textile nanocomposites with antimicrobial activity against antibiotics-resistant bacterial strains and yeast. Modification of cotton fabric with oxalic acid solutions ...
The influence of synthesis conditions on the redox behaviour of LiFePO4 in aqueous solution
(Elsevier Science Sa, Lausanne, 2019)
To contribute to the knowledge on the influence of synthesis procedure on the intercalation kinetics of lithium ions into phospho-olivines, LiFePO4/C composite samples (LFPC) were synthesized in two ways, the first one in ...
Abnormalities in the ovule development of the European plum cultivar 'Pozna Plava' in the days following anthesis
(Elsevier Science Bv, Amsterdam, 2019)
Factors such as the stage of ovule maturity and longevity at flowering, when the stigma is able to receive the pollen, are significant in terms of fruit set. Various abnormalities during ovule development can often limit ...
