Synthesis of Tribological WS2 Powder from WO3 Prepared by Ultrasonic Spray Pyrolysis (USP)
(MDPI, Basel, 2019)
This paper describes the synthesis of tungsten disulfide (WS2) powder by the sulfurization of tungsten trioxide (WO3) particles in the presence of additive potassium carbonate (K2CO3) in nitrogen (N-2) atmosphere, first ...
Nitrogen plasma surface treatment for improving polar ink adhesion on micro/nanofibrillated cellulose films
(Springer, Dordrecht, 2019)
We find that nitrogen plasma treatment of micro/nanofibrillated cellulose films increases wettability of the surface by both liquid polar water and nonpolar hexadecane. The increased wetting effect is more pronounced in ...
Temperature fields in linear stage of friction stir welding effect of different material properties
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Friction stir welding is one of the procedures for joining the parts in solid state. Thermo-mechanical simulation of the friction stir welding of high-strength aluminium alloys 2024 T3 and 2024 T351 is considered in this ...
Immobilization of Aspergillus Niger cellulase onto Lifetech TM carriers and its application in the hydrolysis of sunflower seed meal lignocellulosic fraction / Imobilizacija Aspergillus Niger celulaze na Lifetech TM nosače i primena u reakciji hidrolize lignocelulozne frakcije suncokretove sačme
(Institute for Food Technology, Novi Sad, 2019)
Cellulases are enzymes which catalyse cellulose hydrolysis and are widely used in various industry branches. Lately, their application in treatment of different agroindustrial waste materials which could serve for fuel ...
Mechanical properties and microstructure of the ZrO25CaO/NiCrAl coating system / Mehaničke osobine i mikrostruktura sistema prevlaka ZrO25CaO/NiCrAl
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
ZrO25CaO is a versatile class of material that can be sintered or plasma spray deposited in combination with other materials on the implant substrate. Due to brittleness the organic ceramic hydroxyapatite Ca10(PO4)6(OH)2 ...
Mechanical properties and microstructure of molybdenum coating layers deposited vacuum plasma spray process / Mehanička svojstva i mikrostruktura slojeva prevlake molibdena deponovane vakuum plazma sprej procesom
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
Molybdenum coatings due to their excellent wear resistant properties and sliding characteristics under dry friction conditions are often used in applications to resist friction and dry sliding. Since molybdenum metal is ...
OXYCELLULOSE – MATERIAL FOR NEW APPLICATION AREAS / OKSICELULOZA – MATERIJAL ZA NOVA PODRUČJA PRIMENE
(Academy of Sciences and Arts of Republic of Srpska, 2019)
In this paper, the principles of the action of the selective (NaIO4 and
2,2,6,6-tetramethylpiperidine-1-oxyl-TEMPO radical) and non-selective (H2O2 and
KMnO4) oxidation agents on cellulose are presented. Their importance ...
Influence of Different Pretreatments on the Antibacterial Properties of Chitosan Functionalized Viscose Fabric: TEMPO Oxidation and Coating with TEMPO Oxidized Cellulose Nanofibrils
(MDPI, Basel, 2019)
The main objective of this study was to obtain chitosan functionalized viscose fabric with improved antibacterial properties and washing durability. In this regard carboxyl and aldehyde groups, as binding points for ...
Hydrothermal synthesis of TiO2/carbon composites and their application for removal of organic pollutants
(Elsevier, Amsterdam, 2019)
TiO2/carbon composites were synthesized by hydrothermal carbonization, using titanium isopropoxide and glucose precursor solution to obtain composites with Ti/C molar ratios ranging from 0.05 to 0.30. Characterization of ...
