Brachybacterium sp CH-KOV3 isolated from an oil-polluted environment-a new producer of levan
(Elsevier, 2017)
Various microorganisms isolated from polluted environments, such as Pseudomonas sp. and Micrococcus sp. can synthesize exopolysaccharides (EPSs) which are natural, non-toxic and biodegradable polymers. EPSs play a key role ...
Benchmarking density functional tight binding models for barrier heights and reaction energetics of organic molecules
(Wiley, Hoboken, 2017)
Density Functional Tight Binding (DFTB) models are two to three orders of magnitude faster than ab initio and Density Functional Theory (DFT) methods and therefore are particularly attractive in applications to large ...
in/out Isomerism of cyclophanes: a theoretical account of 2,6,15-trithia-[3(4,10)][7]metacyclophane and [3(4,10)][7]metacyclophane as well as their halogen substituted analogues
(Royal Soc Chemistry, Cambridge, 2017)
A detailed theoretical investigation of cyclophanes with a divergent set of methods ranging from molecular mechanics through semiempirical to ab initio is presented. Cyclophanes have attracted interest over the years due ...
Metabolomics study of Populus type propolis
(Elsevier, 2017)
Herein, we propose rapid and simple spectroscopic methods to determine the chemical composition of propolis derived from various Populus species using a metabolomics approach. In order to correlate variability in Populus ...
Effect of sepiolite organomodification on the performance of PCL/sepiolite nanocomposites
(Oxford : Pergamon-Elsevier Science Ltd, 2017)
Poly(epsilon-caprolactone) (PCL) based nanocomposites with unmodified and organomodified sepiolites were prepared by solution casting method. The sepiolites were modified with short (3-mercaptopropyl)trimethoxysilane ...
Anticancer potential of new steroidal thiazolidin-4-one derivatives. Mechanisms of cytotoxic action and effects on angiogenesis in vitro
(Oxford : Pergamon-Elsevier Science Ltd, 2017)
The synthesis and cytotoxic activities determination of new steroidal mono- and bis(thiazolidin-4-ones) 4a-f and 5a-f have been performed. Their anticancer action was also evaluated in comparison to previously synthesized ...
Electrochemical behavior of palladium modified amino-functionalized macroporous copolymer
(Elsevier, 2017)
In this study, macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) was synthesized by suspension copolymerization, functionalized by ring-opening reaction of the pendant epoxy groups with diethylene ...
Natural sorbents modified by divalent Cu2+- and Zn2+- ions and their corresponding antimicrobial activity
(Elsevier, 2017)
The objective of this study was to investigate the modification of materials used in wastewater treatment for possible antimicrobial application(s). Granulated activated carbon (GAC) and natural clinoptilolite (CLI) were ...
The influence of mechanical activation on structural evolution of nanocrystalline SrTiO3 powders
(Elsevier, 2017)
Structural changes caused by mechanical activation of SrTiO3 powders were investigated using a variety of methods. Average crystallite size continuously decreased with increased activation time to around 20 nm after 120 ...
Effect of malondialdehyde on the ovalbumin structure and its interactions with T84 epithelial cells
(Elsevier, 2017)
Background: Protein oxidation can occur as a consequence of lipid peroxidation during food processing. The aim of this work was to explore the effect of malondialdehyde (MDA) modification of ovalbumin (OVA) on its interaction ...
