Thermal stability of porcine pepsin influenced by Al(III) ion: DSC study
(Pleiades Publishing, 2011)
Differential scanning calorimetry (DCS) has been used to determine thermodynamic profile of pepsin and the in vitro effect of Al(III) ions. Thermograms of pepsin unfolding in the presence and absence of aluminum were used ...
PMMA-Y2O3 (Eu3+) nanocomposites: Optical and mechanical properties / Nanokompozit PMMA-Y2O3 (Eu3+) - optička i mehanička svojstva
(Serbian Chemical Society, Belgrade, 2011)
The results of a study related to the processing and characterization of poly(methyl methacrylate) (PMMA)-Y2O3 (Eu3+) nanocomposites are presented herein. The nanocomposite samples were prepared using a laboratory mixing ...
Comparative analysis of oxidative synthesis of N-alkyl, N,N-dialkyl and N-cykloalkyl-O-isobutyl thioncarbamate / Uporedna analiza oksidativnih postupaka sinteze N-alkil, N,N-dialkil i N-cikloalkil-O-izobutil tionkarbamata
(Association of Chemical Engineers of Serbia, 2011)
An optimized synthesis of N-alkyl, N,N-dialkyl- and N-cycloalkyl-O-isobutyl thioncarbamates by aminolysis of sodium isobutylxanthogenic acid (NaiBXAc) and primary, secondary and cycloalkyl amines was developed at laboratory ...
Some tactile comfort properties of plain knitted fabrics / Neka svojstva taktilnog komfora glatkih pletenina
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2011)
The sensory perception of textile materials is related to mechanical stimuli due to pressure and friction forces, so the softness and surface properties are considered to be the key parameters of fabric hand. The aim of ...
New trends and challenges in lactic acid production on renewable biomass / Novi pravci i izazovi u proizvodnji mlečne kiseline na obnovljivim sirovinama
(Association of Chemical Engineers of Serbia, 2011)
Lactic acid is a relatively cheap chemical with a wide range of applications: as a preservative and acidifying agent in food and dairy industry, a monomer for biodegradable poly-lactide polymers (PLA) in pharmaceutical ...
Thermal properties of poly(urethane-ester-siloxane)s based on hyperbranched polyester
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Novel polyurethanes (PUs) were synthesized using hydroxy-terminated hyperbranched polyester (BH-20) and 4,4'-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxy-terminated ethylene oxide-poly(dimethylsiloxa ...
Thermal degradation of coordination polymer [Cd(N-Boc-gly)(2)(H2O)(2)](n)
(Elsevier Science Bv, Amsterdam, 2011)
Multi-step thermal degradation of coordination polymer [Cd(N-Boc-gly)(2)(H2O)(2)](n) in non-isothermal conditions was studied. The kinetic parameters were determined from the thermal decomposition data using the isoconversion ...
The evolution of hydrogen from proton irradiated glassy carbon
(Elsevier B.V., 2011)
Glassy carbon was irradiated with 15 key H(+) ion beam. It was observed that the implanted hydrogen is unstable in material and evolves as H, H(2) and H(2)O. Post-irradiation evolution of H, H(2) and H(2)O from proton ...
Effect of soya milk on nutritive, antioxidative, reological and textural properties of chocolate produced in a ball mill / Uticaj sojinog mleka na nutritivna, antioksidativna, reološka i teksturalna svojstva čokolade proizvedene u kugličnom mlinu
(Association of Chemical Engineers of Serbia, 2011)
Chocolate is a complex rheological system in which non-fat cocoa particles and sugar particles are enveloped by crystal matrix of cocoa butter. Physical properties of chocolate depend on ingredient composition, method of ...
