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, ...
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 ...
Low-friction, wear-resistant, and electrically homogeneous multilayer graphene grown by chemical vapor deposition on molybdenum
(Elsevier, 2020)
Chemical vapour deposition (CVD) is a promising method for producing large-scale graphene (Gr). Nevertheless, microscopic inhomogeneity of Gr grown on traditional metal substrates such as copper or nickel results in a ...
Characterisation of the binding of dihydro-alpha-lipoic acid to fibrinogen and the effects on fibrinogen oxidation and fibrin formation
(Elsevier, 2020)
A reduced form of the alpha-lipoic acid, dihydro-alpha-lipoic acid (DHLA) is a potent, naturally occurring antioxidant which can be consumed as food constituent or as supplement at doses up to 600 mg/day. DHLA has inhibitory ...
