Enhanced photocorrosion stability of colloidal cadmium sulphide-silica nanocomposites
(Journal of Materials Science Letters, 1999)
Pyrolysis of pine and beech wood under isothermal conditions: the conventional kinetic approach
(Research on Chemical Intermediates, 2015)
Pyrolysis of pine and beech wood was investigated by isothermal thermogravimetry at five different temperatures (280, 290, 300, 310, and 320 A degrees C) in an atmosphere of flowing nitrogen. It was found that isothermal ...
Fructose-Rich Diet-Induced Changes in the Expression of the Renin Angiotensin System Molecules in the Heart of Ovariectomized Female Rats Could be Reversed by Estradiol
(Hormone and Metabolic Research, 2015)
The renin-angiotensin system has been implicated in the development of metabolic syndrome and appears to be a key in the local tissue control of normal cardiac functions. Physiological concentrations of estrogens have been ...
The influence of the preparation conditions and filler content on thermal properties of poly-L-lactide and hydroxyapatite/poly-L-lactide nanocomposite
(Polymer International, 2017)
Poly-L-lactide (PLLA) and hydroxyapatite/poly-L-lactide (HAp/PLLA) are two widely used biomaterials for three-dimensional scaffolds, drug release matrices and implantable medical devices for reparation of bone tissue; ...
Instrumental function of the SPECS XPS system
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2017)
A simple method for the energy resolution measurement of a spectrometer, working in the fixed analyser transmission mode, is proposed and used to determine the resolution of a SPECS Phoibos 100 spectrometer, being a part ...
Freeze-out radii extracted from three-pion cumulants in pp, p-Pb and Pb-Pb collisions at the LHC
(Physics Letters B, 2014)
In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose-Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted ...
The effect of tropopause height on the content of radioactive debris in surface atmosphere
(Environment International, 1997)
The effect of tropopause height on the content of Cs-137 and total beta activity in surface atmosphere was considered for the period of intensive nuclear weapon tests, from 1968-1971. The activity of Cs-137 in monthly air ...
Natural Diatomite (Rudovci, Serbia) as Adsorbent for Removal Cs from Radioactive Waste Liquids
(Science of Sintering, 2015)
The removal of Cs (I) ions from aqueous solution was studied using natural diatomite as adsorption materials originated from Rudovci, Serbia. The microstructure of natural diatomite has been characterized by X-ray diffraction ...
Room-temperature luminescence of AgBr quantum dots
(Chemical Physics Letters, 1999)
A new method for the preparation of 25 Angstrom AgBr quantum dots has been developed. The room-temperature emission of size-restricted AgBr crystallites was observed. The emission spectrum of 25 Angstrom AgBr quantum dots ...
Fast hydrogen sorption from MgH2-VO2(B) composite materials
(Journal of Power Sources, 2016)
The hydrogen sorption kinetics of MgH2-VO2(B) composites synthesised by mechanical milling have been studied. The microstructural properties of composites were characterized by means of X-ray diffraction (XRD), Raman ...
