Fluorination as a Driving Force in Crystal Structures
(Commission on Quantum Crystallography of IUCr, 2020)
The results of the crystallographic analysis in combination with quantum chemical calculations have shown that fluorination of organic compounds causes an increase in the proton-donating ability and a decrease in the ...
Application of image analysis for cavitation erosion resistance monitoring of some engineering materials
(Bor : University of Belgrade, Technical Faculty, 2023)
Engineering materials are often used in various operating conditions including high temperatures,
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected
when fluid flow ...
Applying concept of 3d printing concrete in wind tower construction / Primena koncepta 3d štampe betona u izradi vetrogeneratora
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Although a most prominent material in contemporary construction practice due to its’ obvious advantages, concrete incorporates a number of drawbacks. It is one of the most advantageous principles for decades to enable a ...
Alkalno aktivirani leteći pepeo modifikovan polietileniminom kao adsorbent za uklanjanje metilensko plavog iz vode / Alkali-activated fly ash modified with polyethyleneimine as adsorbent for methylene blue removal from water
(Beograd : Srpsko hemijsko društvo, 2023)
U cilju iskorišćenja industrijskog otpada, leteći pepeo je modifikovan radi dobijanja
efikasnih adsorbenata za uklanjanje metilensko plavog iz vode. Leteći pepeo je aktiviran u
prisustvu NaOH na 550oC, i modifikovan ...
Detekcija i identifikacija mikroplastike iz sedimenata međunarodnih reka u Srbiji / Detection and identification of microplastics from the sediments of international rivers in Serbia
(Beograd : Srpsko hemijsko društvo = Serbian Chemical Society, 2021)
Poslednjih decenija mikroplastika je prepoznata kao jedan od glavnih zagađivača životne sredine.
Nastaje kao posledica postepene degradacije/fragmentacije većih čestica plastike usled izloženosti
različitim faktorima ...
Investigation of antioxidant activity of 6-hydroxy-6-methyl-2-pyridones / Ispitivanje antioksidativne aktivnosti azo boja na bazi 6--hidroksi-4-metil-2-piridona
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2022)
Considering a significant antioxidant activity of 6-hydroxy-6-methyl-2-pyridones, in this paper four series of arylazo pyridone dyes were subjected to antioxidant ABTS assay. Firstly, preliminary tests were conducted at ...
Optimization of Bioreactor Cultures of Glioblastoma Cells Immobilized in Alginate Microfibers
(Institute of Technical Sciences of SASA, 2021)
Glioblastoma is the most common and aggressive malignant brain tumor in adults. Existing
treatment choices that include surgery, radiation and chemotherapy are not successful in
long-term survival, while development of ...
BIOMIMETIC BIOREACTORS IN CHARACTERIZATION OF NOVEL BIOMATERIALS
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2022)
Development of novel biomaterials for potential biomedical applications requires comprehensive preclinical studies. Traditional methods for biomaterial evaluation are based on in vitro testing routinely performed in monolayer ...
Forced periodic reactor operation
(Max Planck Institute, 2020)
We used the nonlinear frequency response (NFR) method in order to identify forced periodic conditions under which the acetic acid anhydride hydrolysis (chosen as a test reaction) can be favorably performed in a CSTR. Based ...
Analysis and interpretation of the micromechanical properties measurements of electrodeposited nickel coatings on different substrates.
(Belgrade : Academy of Criminalistic and Police Studies, 2020)
Fine-grained nickel coatings were electrodeposited by direct current (dc) regime onto different substrates: polycrystalline cold-rolled copper, polycrystalline brass and single crystal (100)-oriented silicon. These composite ...
