Structural and functional characterization of papain-assisted ultrasound pretreated egg white hydrolysis
(Portugal : Proteomass, 2016)
The main objective of this research is to quantitatively investigate the impact of high intensity
ultrasound waves generated by probe-type sonicator on the selected functional and structural properties of papainassisted ...
Effect of the alkali treatment on the structure, moisture sorption and volume electrical resistivity of woven jute fabrics / Uticaj alkalnog tretmana na strukturu, sorpciju vlage i zapreminsku električnu otpornost tkanina od jute
(Beograd : Serbian Chemical Society, 2019)
Woven jute fabric was treated with NaOH solution of different concentrations for 5 min to
obtain jute fabrics with gradually decreased content of hemicelluloses and increased
moisture sorption. With increasing the ...
DETERMINATION OF THERMAL CONDUCTIVITY OF THE INSULATION MATERIALS USING NUMERICAL CALCULATION OF THE PRESSURE INCREASE
(Materials Research Society of Serbia, Crna Gora, 2011)
In the paper is presented the possibility of determination thermal conductivity for the
insulation materials, which are used in the tanks for liquid carbon dioxide, in situ. For this
purpose, was developed the mathematical ...
DIELECTRIC LOSS TANGENT OF ALKALI TREATED JUTE WOVEN FABRICS: EFFECT OF HEMICELLULOSES CONTENT / TANGENS DIELEKTRIČNIH GUBITAKA ALKALNO TRETIRANIH TKANINA OD JUTE: EFEKAT SADRŽAJA HEMICELULOZA
(Belgrade : Union of Engineers and Technicians of Serbia, 2019)
The jute woven fabric was treated with sodium hydroxide at room
temperature for 5, 30 and 45 min in order to obtain jute fabric with different
hemicelluloses content and to study their influence on the dielectric loss ...

(Beograd : Srpsko hemijsko društvo, 2015)
Cilj ovog rada bio je ispitivanje načina adsorpcije i raspodele odabranih lekova i pesticida između vodene faze i sedimenta, kao i određivanje stepena adsorpcije i desorpcije na sedimentu reke Dunav. Rezultati adsorpcije ...
THE INFLUENCE OF THE ALKALI TREATMENT ON THE PROPERTIES OF JUTE WOVEN FABRICS / UTICAJ ALKALNOG TRETMANA NA SVOJSTVA TKANINA JUTE
(Beograd : The College of Textile Design, Technology and Management, 2018)
In this investigation, jute woven fabric has been alkali treated with NaOH solution (1%, 5%, 10% and 17.5%) at room temperature for different periods of time (5 and 30 min). The influence of different treatment conditions ...
SEM-EDS analysis of gold mercaptotriazole crystals (Au-MT)
(Belgrade : Serbian Society for MicroscopyBelgrade : Institute for Biological Research "Siniša Stanković", 2019)
An electrolyte based on gold complex with mercaptotriazole was synthesized in a wide pH range
from acid to alkaline (pH=2-12). After synthesis of the electrolyte, detailed characterization of the
complex in liquid and ...
Stability of the gold mercaptotriazole complex at pH=4
(Bor : Mining and Metallurgy Institute, 2018)
The objective of this work was to investigate the stability of the gold complex based on
mercaptotriazole in slightly acid media, at pH=4. The gold complex complex was studied by the visual monitoring and electrochemical ...
Influence of the alkali treatment conditions on the chemical composition and capillarity of the jute woven fabrics
(Beograd : Serbian Chemical Society, 2018)
Jute fibers have been subjected to various types of chemical modifications to improve their suitability as textile materials. Among them, the alkali treatments have been widely used as the most direct and ecological chemical ...
CHARACTERIZATION OF THE ANODIC FILMS FORMED ON THE Ag60Cu26Zn14 ALLOY BY THE LDI MASS SPECTROMETRY
(Bor : Mining and Metallurgy Institute, 2018)
Precise, direct and fast methods for characterization the anodic films still have to be developed, since the conventional methods cannot be accelerated beyond the certain limits. The present work uses a laser desorption/ionization ...
