Influence of TEMPO-Mediated Oxidation on Properties of Hemp Fibers
(Amer Chemical Soc, Washington, 2012)
Hemp fibers are a very interesting natural material for textile and technical applications, but some of these applications require improved and/or specific fiber properties. In order to modify hemp fibers for obtaining ...
Microencapsulation of natural antioxidants from Pterospartum tridentatum in different alginate and inulin systems
(6th Central European Congress on Food, CEFood 2012, 2012)
The bioactivity of natural antioxidants from plant extracts is well known. Still, the effectiveness of these natural antioxidants, namely polyphenols, depends on preserving their stability, which can be increased by ...
Molecular Sieves: Aluminophosphates
(John Wiley and Sons Inc, 2011)
Aluminophosphate molecular sieves exhibit structural and compositional diversity. Their frameworks can be modified by other elements, thus providing novel silicoaluminophosphate (SAPO), metaloaluminophosphate (MAPO), and ...
Chromatographic behavior and lipophilicity of s-triazine derivatives on silica gel impregnated with paraffin oil
(Univerzitet u Novom Sadu, 2010)
The chromatographic behavior of four group of s-triazine derivatives (14 compounds) has been studied by TLC on silica gel impregnated with paraffin oil. Retention mechanism has been determined using the following mobile ...
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 ...
Uticaj akumulativnog spajanja valjanjem (ARB) i konvencionalnog valjanja (CR) na korozionu stabilnost AA5083 legure / Influence of accumulative roll bonding (ARB) and conventional cold rolling (CR) on the corrosion stability of AA5083 alloy sheets
(Beograd : Srpsko hemijsko društvo, 2018)
Ispitivan je uticaj stepena i načina deformacije na korozionu stabilnost legure AA5083 koja
je procesirana konvencionalnim valjanjem (CR) i akumulativnim spajanjem valjanjem (ARB).
Koroziona stabilnost je praćena standardnim ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...
Uticaj oksidacije na strukturu i površinsko naelektrisanje pamučne pređe / Influence of oxidation on the structure and surface charge of cotton yarn
(Beograd : Srpsko hemijsko društvo, 2019)
In this work, an influence of oxidation with potassium
permanganate (KMnO4) of different concentration, on the structure,
sorption properties and surface charge of cotton yarn was investigated.
Cotton oxidation was ...
The effect of boron incorporation on the structure and properties of glassy carbon
(Elsevier Ltd., 2011)
Boron was introduced into glassy carbon by chemical modification and by irradiating the precursor polymer with boron ions. Using chemical modification, a polymer with uniform distribution of boron in the bulk was obtained, ...
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 ...
