SR-FTIR spectro-microscopic interaction study of biochemical changes in HeLa cells induced by Levan-C60, Pullulan-C60, and their cholesterol-derivatives
(Elsevier, 2020)
Abstract
Objects of the present study are improved fullerene C60 drug carrier properties trough encapsulation by microbial polysaccharides, levan (LEV), pullulan (PUL), and their hydrophobized cholesterol-derivatives (CHL ...
Eliminating dissolution of platinum-based electrocatalysts at the atomic scale
(Nature Publishing Group, 2020)
A remaining challenge for deployment of proton-exchange membrane fuel cells is thelimited durability of Pt-nanoscale materials that operate at high voltages during thecathodic oxygen reduction reaction. In this work, ...

Five NiO/TiO2 materials with a different mass ratiо оf NiO tо TiO2 (3.3, 6.7, 16.3, 23.7, and 36.8%) were synthesized by wet impregnation process and characterized by DR UV-vis, scanning electrоn micrоscоpe, transmissiоn ...
Antistaphylococcal and biofilm inhibitory activities of Frangula alnus bark ethyl-acetate extract
(Elsevier, 2020)
Staphylococcus aureus is one of the leading causative of numerous infections that is resistant to various antibiotics. Since that we are facing with a serious problem of bacterial resistance it is necessary to find a new ...
Aluminum-based self-powered hyper-fast miniaturized sensor for breath humidity detection
(Elsevier, 2020)
An aluminum-based, self-powered, miniaturized sensor for breath humidity detection is presented. The sensor is designed as an interdigitated capacitor made out of sputtered aluminum 1 % silicon (Al 1 %Si) thin film, 700 ...
Littoral eutrophication indicators are more closely related to nearshore land use than to water nutrient concentrations: A critical evaluation of stressor-response relationships
(Elsevier, 2020)
Biological assessmentmetrics and water chemistry measurements are used to quantify the link between stressors
and their effects on lake ecosystems, for the Water Framework Directive. However, correlations between ...
Optimization of microbial fuel cell operation using Danube River sediment
(Elsevier, 2020)
One of the main global focuses of mankind today is the required switch to new energy sources. Generating energy from waste is one of the potential solutions that can be achieved using microbial fuel cells (MFCs). Microorganisms, ...
Dynamic stability of active sites in hydr(oxy)oxides for the oxygen evolution reaction
(Springer Science and Business Media LLC, 2020)
The poor activity and stability of electrode materials for the oxygen evolution reaction are the main bottlenecks in the water-splitting reaction for H2 production. Here, by studying the activity–stability trends for the ...
Carbohydrate – Protein aromatic ring interactions beyond CH/π interactions: A Protein Data Bank survey and quantum chemical calculations
(Elsevier, 2020)
The geometries of the contacts between monosaccharides and aromatic rings of amino acids found in X-ray crystallography structures, in the Protein Data Bank (PDB), were analyzed, while the energies of the interactions were ...
Activation of Oxone® with plasma deposited mixed cobalt and alumina oxide for the dye degradation
(Elsevier, 2020)
The aim of this work is to examine the possibility of the formation of cobalt doped Al2O3 coatings on aluminum substrate by plasma electrolytic oxidation process (PEO) and application of the obtained material as catalyst ...
