Synthesis and Solvatochromic Properties of Novel Azo-azomethine Dyes / Sinteza i solvatohromna svojstva novih azo-azometinskih boja
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2020)
Dyes bearing imino group along with azo one in the structure, present the class of azo-azomethine dyes. Azomethine compounds, known as Schiff bases, find application in biomedical research considering their potential ...
Effects of hydrolysis degree and type of protease on antioxidant activity and functionality of egg white protein hydrolysates
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2013)
Enzymatic hydrolysis of egg white proteins has shown great potential to improve their functional properties such as increased solubility, stability, and digestibility, and to reduce protein allergenicity while still retaining ...
The effect of Ni content on passivation of copper anodes with non-standard chemical composition
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
In this paper are presented the results of the first appearance of full pasivation during the treatment of the waste sulphuric-acid solution generated in the conventional copper electrorefining process. The copper anodes ...
In-vitro visualization of primary tumor cells using up-conversion nanophosphors
(Belgrade : Serbian Ceramic Society, 2017)
For such purpose, Ln-UCNPs should have specific morphological characteristics and efficient luminescence response. In this work, a biocompatible and water dispersible NaYF4:Yb,Er"PLGA nanoparticles synthesized using a ...
Partitioning and purification of cellulases in aqueous two-phase system
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
Aqueous two-phase systems can be formed by mixing the solutions of two mutually incompatible polymers or polymer and salt above critical concentrations and represent media that are very well suited for the separation and ...
Enzymatic Synthesis of Aliphatic Esters of Phenolic Acids and Evaluation of Their Antioxidant Properties
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
The esterification activity of the commercial immobilized lipase CALB towards cinnamic acids and its derivative has been studied. Using cinnamic acid as substrate, the reaction rate constants (1.95 h-1 mM-1 for ethanol and ...
The influence of current density on charge/discharge characteristics of polyaniline electrode
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
Polyaniline (PANI) was electrochemically synthesized on graphite electrode galvanostaticaly from aqueous solution of 0.25 mol dm-3 aniline and 0.5 mol dm-3 p-toluenesulfonic acid. Charge capacity available for the exchange ...
Asymmetric hydrogel membranes for heavy metal adsorption
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Hydrogels containing strong acid groups have been used in the past for the removal of heavy metals. Unfortunately such hydrogels exhibit poor mechanical properties and are generally difficult to handle. In this work we ...
Technological analysis for machining of the reformers for fuel cells testing
(Innovation Center of Faculty of Mechanical Engineering, 2017)
Reformer is an integral component of the polymeric electrolyte membrane (PEM) fuel cell and it is used for
experimental combustion testing. By analyzing the geometry of the experimental reformer, it consists of three
plates, ...
Asymmetric polyethersulfone membranes with crosslinked poly(glycidyl methacrylate) particles
(Belgrade : Serbian Chemical Society, 2013)
Polyethersulfone (PES) is frequently used for high-performance ultrafiltration membranes. Functionalization of PES membranes is required to introduce new groups for specific applications, such as affinity membranes for ...
