Quality of chemically modified hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
Hemp fibers are very interesting natural material for textile and technical applications now. Applying hemp fibers to the apparel sector requires improved quality fibers. In this paper, hemp fibers were modified with sodium ...
Trans- and cis-resveratrol concentration in wines produced in Serbia / Koncentracija trans- i cis-rezveratrola u vinima proizvedenim u Srbiji
(Serbian Chemical Soc, Belgrade, 2008)
Resveratrol, which occurs in two isomeric forms, trans and cis, is a phytoalexin with numerous pharmacological activities, such as anti-cancer, antiviral, neuroprotective and anti-aging. Red wine is the main source of the ...
Structural characteristics of some ternary Ag-In-Sn alloys
(Savez inženjera metalurgije Srbije, Beograd, 2008)
The Ag-In-Sn system, as one of potential lead-free solder materials, was studied in this paper. The investigated alloys were chosen from two sections, with molar ratio of In:Sn equal to 1:4; 1:2. DTA, XRD, SEM and micro ...
The effect of heat treatment on toughness and wear resistance of Fe-Cr-C-Nb alloys / Uticaj termičke obrade na žilavost i otpornost na habanje Fe-Cr-C-Nb legura
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Alloying with niobium improves the mechanical properties of the high chromium irons. The alloy containing appriximately 3 %Nb gives the best compromise between wear resistance and toughness. These properties were improved ...
Electrodeposition of Ni-Mo alloy coatings and their characterization as cathodes for hydrogen evolution in sodium hydroxide solution
(Elsevier, 2008)
The hydrogen evolution reaction on the electrodeposited Ni-Mo alloy coatings, as well as their electrochemical properties in the NaOH solutions, have been investigated by the polarization measurements, cyclic voltammetry ...
Toksičnost i kinetika otpuštanja insulina iz hormonaktivnih polisaharidnih vlakana
(Univerzitet u Beogradu - Medicinski fakultet, Beograd, 2008)
In this paper an account of biocompatibility of a hormonactive fiber in the form of biologically active complex chitosan-insulin is presented. The behavior of artificial depots of insulin containing 180-330mg of insulin ...
A kinetic study of the thermal degradation of cetyltrimethylammonium bromide inside the mesoporous SBA-3 molecular sieve
(Elsevier Science Bv, Amsterdam, 2008)
Thermal degradation of cetyltrimethylammonium bromide (CTMAB) inside the mesoporous SBA-3 has been studied under non-isothermal conditions. There are two distinct although partly overlapping kinetic processes, and both of ...
Electrocatalytic properties and stability of titanium anodes activated by the inorganic sol-gel procedure / Titanske anode aktivirane oksidnom prevlakom dobijenom sol-gel postupkom
(Serbian Chemical Society, 2008)
The properties of activated titanium anodes, RuO2-TiO2/Ti and RuO2--TiO2-IrO2/Ti, prepared from oxide sols by the sol-gel procedure, are reviewed. RuO2 and TiO2 sols were synthesized by forced hydrolysis of the corresponding ...
Energijski potencijali u svetu i njihov značaj u celulozno-papirnoj industriji / Energy potentials worldwide and their importance in cellulose and paper industry
(Association of Chemical Engineers of Serbia, 2008)
Radom se ukazuje na raspoložive svetske izvore energije. Razmatra se korišćenje
energije u narednom periodu. Daje se pregled, upotreba i značaj alternativnih
izvora energije. Potencira se neophodnost razvoja novih ...
Two new examples of very short thallium-transition metal contacts: Tl(3)Ag(3)Sb(2)S(6) and Tl(3)Ag(3)As(2)S(6)
(Elsevier Science Sa, Lausanne, 2008)
Two new sulphosalts Tl(3)Ag(3)Sb(2)S(6), (1) and Tl(3)Ag(3)AS(2)S(6), (2) were prepared in reaction of synthetic binary sulfides: argentite (Ag(2)S), carlinite (Tl(2)S) and orpiment (As(2)O(3)) or stibnite (Sb(2)S(3)), and ...
