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 ...
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 ...
Synthesis and characterization of 1-(4-substitutedbenzyl)-3’,4’-dihydro-2’H-spiro[imidazolidine-4,1’-naphtalene]-2,5-dione derivatives as potential anticonvulsant agents / Sinteza i karakterizacija 1-(4-supstituisanih benzil)-3’,4’-dihidro-2’H-spiro[imidazolidin-4,1’-naftalen]-2,5-diona potencijalnih antikonvulzivnih agenasa
(Beograd : Serbian Chemical Society, 2018)
Among the diverse pharmacological activity reported for spirohydantoin and the closely related spirosuccinimides, their anticonvulsant and antiproliferative activities are commonly encountered. Of all cyclic ureide ...

Protein-repellent and antioxidative properties of bioactive coatings based on TEMPO oxidized cellulose nanofibrils and chitosan / Protein-odbijajuća i antioksidativna svojstva bioaktivnih prevlaka na bazi TEMPO oksidisanih celuloznih nanofibrila i hitozana
(Beograd : Serbian Chemical Society, 2018)
In this work, regenerated cellulose (RC) films was coated with
TEMPO oxidized cellulose nanofibrils (TOCN) and chitosan (CS) by means of
subsequent spin-coated deposition. The bioactivity of coatings was
achieved by ...
