Simultaneous enhancement of natural sunlightand artificial UV-driven photocatalytic activity of a mechanically activated ZnO/SnO2 composite
(Royal Soc Chemistry, Cambridge, 2017)
Mechanical milling of commercial ZnO and SnO2 was used to produce a ZnO/SnO2 composite with a high density of surface defects; in particular, zinc interstitials (Zni) and oxygen vacancies (VO). To determine the impact of ...
The Bridgman Method Growth and Spectroscopic Characterization of Calcium Fluoride Single Crystals
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2016)
It must be noted that the main objective of this study was to obtain single crystals of calcium fluoride - CaF2, and after that the crystals were characterized with various spectroscopic methods. The crystals were grown ...
Electrochemical synthesis of nanosized hydroxyapatite/graphene composite powder
(Springer Japan Kk, Tokyo, 2015)
Electrochemical synthesis was employed to prepare a novel hydroxyapatite/graphene (HAP/Gr) composite powder suitable for medical applications as a hard tissue implant (scaffold). The synthesis was performed in a homogeneous ...
CO2 conversion enhancement in a periodically operated Sabatier reactor: Nonlinear frequency response analysis and simulation- based Study
(The 25th International Symposium of Chemical Reaction Engineering (ISCRE 25), Florance, Italy, 2018)
Nonlinear frequency response (NFR) analysis was applied on a Sabatier reactor. A substantial improvement in CO2 conversion was predicted under certain conditions. The NFR analysis prediction was validated using a kinetic ...
Computer-Aided Nonlinear Frequency Response Method for Investigating the Dynamics of Chemical Engineering Systems
(MDPI, Basel, 2020)
The Nonlinear Frequency Response (NFR) method is a useful Process Systems Engineering tool for developing experimental techniques and periodic processes that exploit the system nonlinearity. The basic and most time-consuming ...
Development of the automated software and device for determination of wicking in textiles using open-source tools
(Public Library Science, San Francisco, 2020)
The development of automated software and the device for determination of wicking of textile materials, using open-source ImageJ libraries for image processing, and newly designed additional algorithm for the determination ...
Lead isotope ratios as tool for elucidation of chemical environment in a system of Macrolepiota procera (Scop.) Singer - soil
(Springer Nature, 2020)
The analysis of isotope ratios of lead in the mushrooms and soil, where they were grown, assisted with a principal component analysis, offered a new perspective for understanding possible chemical environment in a real ...
Influence of Nuclear Radiation and Laser Beams on Optical Fibers and Components
(Nuclear technology and radiation protection, 2011)
The influence of nuclear radiation and particles has been the object of investigation for a long time. For new materials and systems the research should be continued. Human activities in various environments, including ...
Surface functionalization of oxidized multi-walled carbon nanotubes: Candida rugosa lipase immobilization
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2016)
This work examines two approaches for immobilization of lipase from Candida rugosa on oxidized multi-walled carbon nanotubes (o-MWCNTs). One method included the presence of activating agents to promote covalent bonding and ...
Modification of multi-wall carbon nanotubes for the removal of cadmium, lead and arsenic from wastewater
(Inst Materials Physics, Bucharest, 2013)
Multi-wall carbon nanotubes (MWCNTs) was functionalized with 6-arm amino polyethylene glycol (PEG), and synthesized PEG-MWCNTs was used as adsorbent in order to study adsorption characteristics with respect to Cd(II), ...
