Experimental and theoretical UV-Vis spectral study of some arylazo pyridone dyes in amide solvents
(Belgrade : Society of Physical Chemists of Serbia, 2021)
Spectral properties of ten 5-(substituted phenylazo)-3-cyano-1-ethyl-6-hydroxy-4-methyl-2-pyridones were investigated in formamide and N,N-dimethylformamide (DMF) by combining experimental study and density functional ...
WS2 nanostructures as thermo-mechanical reinforcement of composite materials for advanced applications
(Abstract Book / 3 rd Edition of Materials Science and Nanoscience Webinar, V-Mat2021, September 17-18, 2021, 2021)
As one of transition metal dichalogenides, tungsten disulphide (WS2) is well known for its solid
lubricating behavior, but besides this feature, it exhibits extraordinary thermal stability and mechanical
resistance. The ...
Microstructure and mechanical properties of anodized surface of ultrafine-grained Ti-13Nb-13Zr alloy for biomedical application
(Innovation Center of Faculty of Mechanical Engineering, Belgrade, 2021)
Anodized surface on coarse-grained (CG) and ultrafine-grained (UFG) Ti-13Nb-13Zr alloy was obtained using electrochemical surface modification in the 1M H3PO4 + NaF electrolyte. Scanning electron microscopy (SEM) was used ...
Influence of the electrochemical anodization on the surface roughness of Ti-13Nb-13Zr medical alloy
(Univerzitet u Beogradu, Mašinski fakultet, 2021)
Surface roughness is one of the influencing factors on the friction and wear mechanism of metallic materials. However, surface roughness of metallic biomaterials plays a major role in assessing the biocompatibility and ...
Kinetic and desorption study of vanadium (V) on magnetic amino-functionalized polymer/bentonite sorbents
(Leskovac : Faculty of Technology, 2021)
Vanadium and its compounds have multiple applications in industry, such as in alloys to increase strength and as a catalyst. Vanadium(V) is the dominant form in the aquatic environment and also, it is the most hazardous ...
Investigation of sorption behavior of Cu(II) and Pb(II) onto a novеl EDTA modified copolymer
(Belgrade : Society of Physical Chemists of Serbia, 2021)
A new metal-chelating glycidyl methacrylate based macroporous copolymer with
ethylenediaminetetraacetic acid functions was tested as a potential Cu(II) and Pb(II) ions sorbent from
aqueous solutions. The sorption was ...
