New Theoretical Insight into Fluorination and Fluorine–Fluorine Interactions as a Driving Force in Crystal Structures
(American Chemical Society (ACS), 2020)
Fluorination of compounds causes an increase in the proton-donating ability and a decrease in the proton-accepting capacity of groups in their vicinity. The formation of F···F interactions is followed by the shift of the ...
Floating-Gate MOS Transistor with Dynamic Biasing as a Radiation Sensor
(MDPI, 2020)
This paper describes the possibility of using an Electrically Programmable Analog Device (EPAD) as a gamma radiation sensor. Zero-biased EPAD has the lowest fading and the highest sensitivity in the 300 Gy dose range. ...
Phytochemicals from bryophytes: Structures and biological activity / Фитохемикалије из бриофита: структура и биолошке активности
(Serbian Chemical Society, 2021)
Little attention has been paid to the bryophytes as sources for human diet despite the presence of 23,000 species in the world. Some mosses contain Vitamin B1, tocopherols, prostaglandin-like highly unsaturated fatty acids ...
The structural, electrical and optical properties of spark plasma sintered BaSn1-xSbxO3 ceramics
(Elsevier, 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) ...
Genetic and morphological variation in Chara contraria and a taxon morphologically resembling Chara connivens
(Taylor & Francis, 2020)
Charophyte species delineation is regularly based on a set of thallus morphological character- istics, but considering pronounced phenotypic plasticity, difficulties and doubts commonly occur in Chara species determination. ...
Curcumin loaded pegylated nanoemulsions designed for maintained antioxidant effects and improved bioavailability: A pilot study on rats
(MDPI, 2021)
The current study describes the experimental design guided development of PEGylated nanoemulsions as parenteral delivery systems for curcumin, a powerful antioxidant, as well as the evaluation of their physicochemical ...
Influence of microstructure and roughness level on corrosion resistance of the austenitic stainless steel welded joint
(Wiley, 2021)
The influence of microstructure and surface roughness of the X5CrNi18-10 austenitic stainless steel-welded joint on resistance to uniform, pitting, and intergranular corrosion, as well as on the stability of the passive ...
GC-FID-MS Based Metabolomics to Access Plum Brandy Quality
(MDPI, 2021)
Plum brandy (Slivovitz (en); Šljivovica(sr)) is an alcoholic beverage that is increasingly consumed all over the world. Its quality assessment has become of great importance. In our study, the main volatiles and aroma ...
Constrained-group-delay-optimized multiple-resonator-based harmonic analysis
(Slavonski Brod: Strojarski fakultet, 2021)
Recently, a multiple-resonator structure was proposed as a robust and computationally efficient tool for harmonic analysis. Two trivial cases have been previously observed. The first case exhibits good out-of-band suppression ...
Flavonoids of the Heartwood of Cotinus coggygria Scop. Showing Protective Effect on Human Lymphocyte DNA
(SAGE Publications, 2021)
In continuation of our study on Cotinus coggygria from Serbia, 10 known flavonoids (1-10) were isolated from the methylene chloride/ methanol extract of the heartwood. They were tested for in vitro protective effect against ...
