Micromechanical analysis of fatigue and crack growth in carbon-fiber epoxy composites based on mechanical testing
(Savez hemijskih inženjera, Beograd, 2020)
The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0 degrees/90 degrees and +/- 45 degrees. The main tensile properties were determined as a basis for subsequent dynamic ...
Utilization of the integrated process of supercritical extraction and impregnation for incorporation of helichrysum italicum extract into corn starch xerogel
(Savez hemijskih inženjera, Beograd, 2018)
Supercritical CO2 extraction of Helichrysum italicum and impregnation of starch xerogels with the extract by using an integrated scCO(2) extraction and impregnation process were performed at 350 bar and 40 degrees C in ...
A coupled thermo-mechanical model of friction stir welding
(Vinca Institute of Nuclear Sciences, 2012)
A coupled thermo-mechanical model was developed to study the temperature fields, the plunge force and the plastic deformations of Al alloy 2024-T351 under different rotating speed: 350, 400, and 450 rpm, during the friction ...
Influence of the precursor chemical composition on heavy metal adsorption properties of hemp (Cannabis Sativa) fibers based biocarbon
(Srpsko hemijsko društvo, Beograd, 2017)
Waste hemp (Cannabis sativa) fibers were used as sustainable and renewable raw materials for production of low-cost biocarbon sorbent for heavy metals removal. Carbon precursors of different chemical composition were ...
Validation of a novel perfusion bioreactor system in cancer research
(Savez hemijskih inženjera, Beograd, 2020)
Development of drugs is a complex, time- and cost-consuming process due to the lack of standardized and reliable characterization techniques and models. Traditionally, drug screening is based on in vitro analysis using ...
Tailoring the supercapacitive performances of noble metal oxides, porous carbons and their composites / Rasvetljavanje superkondenzatorskih odlika oksida plemenitih metala, poroznih ugljeničnih materijala i njihovih kompozita
(Serbian Chemical Society, 2013)
Porous electrochemical supercapacitive materials, as an important type of new-generation energy storage devices, require detailed analysis and knowledge of their capacitive performances under different charging/discharging ...
Transition metal complexes with thiosemicarbazide-based ligands. LIII. [4-(2-Diphenylphosphino-a-ethoxybenzyl-κP)-S-methyl-1-(4-oxidopent-3-en-4- ylidene-κO)-thiosemicarbazido-κ 2 N 1 ,N 4 ]nickel(II)
(International Union of Crystallography, 2006)
The title compound, [Ni(C 28 H 30 N 3 O 2 PS)], crystallizes with two independent molecules in the asymmetric unit. The Ni II atoms are in significantly deformed square-planar environments formed by an ONNP donor set from ...
The influence of powder feed rate on mechanical properties of atmospheric plasma spray (APS) Al-12Si coating
(Walter de Gruyter Gmbh, Berlin, 2019)
In this paper, structural and mechanical properties of APS - atmospheric plasma spray coating Al-12Si are presented. The aim of the research was the optimisation of the flow of powder to produce layers with optimal mechanical ...
The influence of thermodynamic parameters on alkaline activators of geopolymers and the structure of geopolymers
(Macedonian Journal of Chemistry and Chemical Engineering, 2021)
Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 degrees C for the process of ...
