Characterization of carbon fibrous material from platanus achenes as platinum catalysts support
(Serbia : Association of Metallurgical Engineers of Serbia, 2020)
Carbon materials with developed porosity are usually used as supports for platinum catalysts. Physico-chemical characteristics of the support influence the properties of platinum deposited and its catalytic activity. In ...
Thermal and microstructural analysis of the low-melting Bi-In-Pb alloy
(Association of Metallurgical Engineers of Serbia (AMES), 2020)
Low-melting alloys, based on bismuth and indium, have found commercial use in soldering, safety devices, coatings, and bonding applications. In this respect, the accurate knowledge of their thermal properties such ...
Biotransformation of Perrottetin F by Aspergillus niger: New Bioactive Secondary Metabolites
(Türkiye : ACG Publications, 2021)
Biotransformation of bis-bibenzyl perrottetin F (1), isolated from the liverwort Lunularia cruciata by Aspergillus niger, has been investigated. New metabolites (2-4) have been isolated using reversed phase semipreparative ...
Ovalbumin interaction with polystyrene and polyethylene terephthalate microplastics alters its structural properties
(Elsevier, 2024)
Contaminating microplastics can interact with food proteins in the food matrix and during digestion. This study investigated adsorption of chicken egg protein ovalbumin to polystyrene (PS, 110 and 260 μm) and polyethylene ...
Microhardness measurement optimization in green derived silica/polyester composites using response surface methodology
(SAGE, 2024)
Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modified
plant provenance biosilica particles were synthesized and characterized. An unsaturated polyester ...
Polyphenol profile and anti-tyrosinase potential of the polypore mushrooms Formitopsis pinicola and Ganoderma lucidum
(Serbian Society for Microbiology, 2024)
Tyrosinase is widely present in plants and mushrooms
and is responsible for enzymatic browning
reactions in damaged foodstuff. Accordingly, its
inhibitors act as anti-browning compounds and
have an important role in ...
Synthetic route towards 1,2,3,4-tetrahydroquinoxaline/piperidine combined tricyclic ring system / Синтетски пут за добијање 1,2,3,4-тетрахидрохиноксалинскo/пиперидинског трицикличног система
(Serbian Chemical Society, 2022)
The synthetic route toward novel tricyclic, nitrogen-containing system is disclosed. Three novel compounds possessing structural features of 1,2,3,4-tetrahydroquinoxaline and decahydropyrido[3,4-b]pyrazine are synthesized ...
Synthesis, Characterization, Catalytic Activity, and DFT Calculations of Zn(II) Hydrazone Complexes
(MDPI, 2020)
Two new Zn(II) complexes with tridentate hydrazone-based ligands (condensation products of 2-acetylthiazole) were synthesized and characterized by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy and single ...
Artificial intelligence-based optimization of a bimorph-segmented tapered piezoelectric mems energy harvester for multimode operation
(MDPI, 2021)
This paper presents a study on the design and multiobjective optimization of a bimorph-segmented linearly tapered piezoelectric harvester for low-frequency and multimode vibration energy harvesting. The procedure starts ...
Possible improvement of methanol synthesis exploiting forced periodic operation: Analysis using the Nonlinear Frequency Responce Method
(The Wilhelm und Else Heraeus-Stiftung, Germany, 2022)
Forced periodic operations, as one way of Process Intensification, can be used in order to achieve better performances of chemical reactors, in comparison to conventional steady-state operation. In this study the Nonlinear ...
