Biomimic hybrid polymer networks based on casein and poly(methacrylic acid). Case study: Ni2+ removal
(Royal Soc Chemistry, Cambridge, 2016)
Mimicking the extraordinary performances of natural materials presents an attractive, but challenging approach in the synthesis of advanced functional materials. In the field of separation techniques, the design of a ...
Volatile organic compounds (VOC) policy innovation in petrochemicals river barge transportation
(Elsevier Sci Ltd, Oxford, 2016)
The aim of this paper was to emphasise the need for a volatile organic compounds VOC policy review in the field of river barge transportation of petrochemicals. Review of the VOC policy shows that barges neither fall under ...
Testing of the functional garments with microencapsulated phase-change material in simulated high temperature conditions
(Savez hemijskih inženjera, Beograd, 2016)
An organic phase change material (PCM) possesses the ability to absorb and release large quantity of latent heat during a phase change process over a certain temperature range. This paper presents results related to ...
Improvement of antioxidant properties of egg white protein enzymatic hydrolysates by membrane ultrafiltration

The production of bioactive peptides from egg white proteins (EWPs) and their separation are emerging areas with many new applications. The objective of this study was to compare antioxidant activity of three distinct EWP ...
Silver release from nanocomposite Ag/alginate hydrogels in the presence of chloride ions: experimental results and mathematical modeling
(Springer, Dordrecht, 2016)
A stepwise experimental and mathematical modeling approach was used to assess silver release from nanocomposite Ag/alginate microbeads in wet and dried forms into water and into normal saline solution chosen as a simplified ...
Synthesis, structure and properties of biological active spirohydantoin derivatives
(Savez hemijskih inženjera, Beograd, 2016)
Spirohidantoins represent an pharmacologically important class of heterocycles since many derivatives have been recognized that display interesting activities against a wide range of biological targets. First synthesis of ...
Failures of Brass Condenser Tubes / Lomovi kondenzatorskih cevi od mesinga
(Institut za ispitivanje materijala, Beograd, 2016)
Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and ...
Ultrasound Pretreatment as an Useful Tool to Enhance Egg White Protein Hydrolysis: Kinetics, Reaction Model, and Thermodinamics
(Wiley, Hoboken, 2016)
