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. ...
Insights into the effect of aluminum oxyhydrates properties on their electrochemical behavior
(Belgrade: Serbian Ceramic Society, 2021)
Alumina oxyhydrates have different structural and textural properties, as well as different density of surface functional groups. Three alumina oxyhydrates with different water content, 3mol H2O/ mol Al2O3 (gibbsite), 1mol ...
Solid green biodiesel catalysts derived from coal fly ash
(IntechOpen, 2020)
Coal fly ash (CFA) is generated during the combustion of coal for energy production. Many studies are based on its utilization as the most abundant, cheap
aluminosilicate industrial residue, which is recognized as a risk ...
Incorporating a Lowpass Filter into a Very Wide Bandpass Filter to Suppress Harmonics
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2021)
This paper presents an algorithm for suppression of higher harmonics in response of the very wide bandpass filter (WBPF). Lowpass filter (LPF) is incorporated into the very wide bandpass filter to suppress harmonics. The ...
A water quality assessment based on benthic diatoms of the timok river basin (Eastern Serbia) under multiple anthropogenic pressures
(Academic Publishing House, 2020)
The study is focused on diatom communities as indicators of the water
quality of aquatic ecosystems. The study included watercourses of the Timok
River Basin in eastern Serbia. Sampling of algological material and ...
Evolution of humic acids during ex situ bioremediation on a pilot level – The added value of the microbial activity / Nastanak huminskih kiselina tokom ex situ bioremedijacije na pilot nivou - dodata vrednost mikrobne aktivnosti
(Belgrade : Serbian Chemical Society, 2020)
Environmental pollution is a global problem, while bioremediation technology removes pollutants from the environment using microorganisms. This study was aimed at investigating how a bioremediation process affected soil ...
Study of Nd deposition onto W and Mo Cathodes from Molten Oxide-Fluoride Electrolyte
(Electrochemical Science Group (ESG), 2020)
Electrochemical reduction processes of Nd(III) on tungsten and molybdenum electrodes in NdF3+LiF and NdF3+LiF+Nd2O3 were investigated by cyclic voltammetry, chronoamperometry and open circuit measurements. Electrolytes and ...
Eco-friendly technology for gel-coat and fireproofing material production using bio-renewable and waste materials
(ООО «Центр «АЮМЭЛЬ», 2020)
Innovative technology has been developed for the production of gelcoat and materials of reduced flammability based on unsaturated polyester resins. These materials were synthesized from raw materials obtained from waste ...
Lampenflora and the entrance biofilm in two show caves: Comparison of microbial community, environmental, and biofilm parameters
(The National Speleological Society, 2020)
Phototrophic microorganisms from two caves in Serbia (Podpeć and Stopić) were examined. Samples were taken from the entrances where natural light was present, as well as from the inside caves near artificial light (lampenflora ...
Genus Humidophila from caves in Serbia with an improved detailed description of rare H. brekkaensoides
(Beograd : Institut za bioloska istrazivanja Siniša Stanković, 2020)
Phototrophic microorganisms can be found in biofilms at entrances to caves where they have access to sufficient
sunlight, water and nutrients; however, they can also be found inside caves, where they are carried by animals ...
