The effect of cesium dopant on APCVD graphene coating on copper
(Elsevier, Amsterdam, 2020)
This study reports in-situ cesium-doped graphene (G/Cs) coating obtained by introducing Cs2CO3 into the atmospheric pressure chemical vapor deposition (APCVD) furnace during graphene deposition on copper. The successful ...
Old Plant, New Possibilities: Wild Bilberry (Vaccinium myrtillus L., Ericaceae) in Topical Skin Preparation
(Antioxidants, 2021)
Bilberry represents a valuable source of antioxidant substances responsible for its application for the treatment of different conditions (such as inflammation, cardiovascular disease, cancer, diabetes, and different ...
Systematic review: gastric microbiota in health and disease
(Wiley, Hoboken, 2020)
Background Helicobacter pylori is the most infamous constituent of the gastric microbiota and its presence is the strongest risk factor for gastric cancer and other gastroduodenal diseases. Although historically the healthy ...
Spatial distribution, radiological risk assessment and positive matrix factorization of gamma-emitting radionuclides in the sediment of the Boka Kotorska Bay
(Marine Pollution Bulletin, 2021)
Surface sediment from the Boka Kotorska Bay (Adriatic Sea) was analyzed for the content of technogenic cesium (137Cs) and naturally occurring (40K, 226Ra, 232Th, 238U) radionuclides. The activity concentrations of the ...
Absorption and fluorescence spectral properties of azo dyes based on 3-amido-6-hydroxy-4-methyl-2-pyridone: Solvent and substituent effects
(Elsevier Sci Ltd, Oxford, 2020)
A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT-IR, H-1 and C-13 NMR, UV-Vis, and PL spectroscopy. Photophysical properties of the dyes were ...
Halochromic cellulose textile obtained via dyeing with biocolorant isolated from Streptomyces sp. strain NP4
(Cellulose, 2021)
Halochromic (pH-responsive) material was obtained by dyeing functionalized viscose fabric with a crude extract from Streptomyces sp. strain NP4. The functionalization of the fabric before dyeing was performed to make ...
Composition and processing effects on the electrochemical characteristics of biomedical titanium alloys
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
The electrochemical behaviour of the Ti-13Nb-13Zr and Ti-6Al-4V ELI alloys with martensitic microstructures was investigated by polarization and electrochemical impedance spectroscopy (EIS) in Ringer's solution. The impedance ...
The structural, electrical and optical properties of spark plasma sintered BaSn1-xSbxO3 ceramics
(Elsevier Sci Ltd, Oxford, 2020)
Antimony doped barium-stannate dense ceramic materials were synthesized using spark plasma sintering technique out of mechanically activated precursor powders. The influence of various Sb concentrations (x = 0.00 - 0.10) ...
Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramicsh
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
Effect of plasma treatment on chemical composition, structure and sorption properties of lignocellulosic hemp fibers (Cannabis sativa L.)
(Elsevier Sci Ltd, Oxford, 2020)
Hemp fibers with different amount of hemicelluloses and lignin were subjected to atmospheric pressure dielectric barrier discharge under different conditions (40 W and 80 W power of discharge, const. time 120 s) in order ...
