Determination of ionization constants of selected monocarbohydrazone derivatives
(Academy of Sciences and Arts of the Republic of Srpska, 2020)
Carbohydrazone derivatives represent a very significant class of compounds due to their wide biological activity. Ionization states of functional groups present in the molecule are of vital importance for understanding of ...
Microwave assisted synthesis of polyaniline/pullulan (pani/pull) composite
(Society of Physical Chemists of Serbia, 2021)
Microwave assisted synthesis of polyaniline modified by pullulan (PANI/Pull) composite was
performed by aniline oxidation with potassium iodate. The PANI/Pull composite was characterized
using ATR-FTIR technique. FTIR ...
Synthesis and characterization of thin copper coatings obtained by sonoelectrodeposition method
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2021)
Influence of an intensity of ultrasonic mixing of electrolyte in a temperature range of 27–37 °C and ultrasonic power intensity in the range of 3.77–18.84 W/cm2 (10–50 %) on a synthesis of fine-grained copper deposits was ...
Molecular and isotope composition of biomarkers in immature oil shale and its liquid pyrolysis products (open and closed system)
(European Association of Geoscientists & Engineers, 2021)
The molecular and isotopic composition of biomarkers in initial bitumen isolated from raw immature oil shale samples from the Lower Miocene Aleksinac Basin (Serbia) and liquid products (LPs) obtained by pyrolysis in open ...
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 ...
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 ...
Examples of Wide Microwave Bandpass Microstrip Filters on Felt Substrate
(Belgrade : Institute of Electrical and Electronics Engineers Inc., 2021)
Application of one type of wide bandpass filter on felt (textile) substrate is introduced. Copper tape and conductive textile are used for metallization (conductive layer). It is an initial work. The patterns were done in ...
Reconstruction of fiber reinforcement in epoxy-based composite
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2021)
Polymer matrix composites (PMCs) are very attractive materials due to a possibility to achieve versatile properties by combining with ceramic or metal reinforcement in different shapes and sizes. As a result, PMCs have ...
