The Effect of the Concentration of Alkaline Activator and Aging Time on the Structure of Metakaolin Based Geopolymer
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2020)
This paper outlines the production of an inorganic polymer/geopolymer using a metakaolin by an environmental friendly, energy saving, clean technology to conserve natural environment and resources. The influence of alkali ...
Evaluation of the Quality of Clothing Fabrics in Terms of Their Compression Behaviour before and after Abrasion
(Korean Fiber Soc, Seoul, 2017)
In this work, the compression behaviour of clothing woven fabrics, before and after abrasion on the Martindale's device, has been examined. Plain and 3/1 twill weave fabrics from cotton and cotton/polyester fiber blends ...
A model for cross-referencing and calculating similarity of metal alloys
(Association of Metallurgical Engineers of Serbia, 2013)
This paper presents an innovative model for the comparison and cross- referencing of metal alloys, in order to determine their interchangeability in engineering, manufacturing and material sourcing. The model uses a large ...
A kinetic study of the thermal degradation of cetyltrimethylammonium bromide inside the mesoporous SBA-3 molecular sieve
(Elsevier Science Bv, Amsterdam, 2008)
Thermal degradation of cetyltrimethylammonium bromide (CTMAB) inside the mesoporous SBA-3 has been studied under non-isothermal conditions. There are two distinct although partly overlapping kinetic processes, and both of ...
Electrophoretically deposited hydroxyapatite-based composite coatings loaded with silver and gentamicin as antibacterial agents
(Srpsko hemijsko društvo, Beograd, 2019)
Increasing need for improved, compatible bone tissue implants led to the intensive research of novel biomaterials, especially hydroxyapatite (HAP)-based composite materials on titanium and titanium alloy surfaces. Owing ...
Natural sorbents modified by divalent Cu2+- and Zn2+- ions and their corresponding antimicrobial activity
(Elsevier Science Bv, Amsterdam, 2017)
The objective of this study was to investigate the modification of materials used in wastewater treatment for possible antimicrobial application(s). Granulated activated carbon (GAC) and natural clinoptilolite (CLI) were ...
Biodiesel density and derived thermodynamic properties at high pressures and moderate temperatures
(Elsevier Sci Ltd, Oxford, 2016)
Knowledge of the basic thermodynamic properties of biodiesel under different conditions is necessary because of its wide use as a substitute for fossil fuels. The viscosities and refractive indices of the methyl and ethyl ...
Medical textiles based on viscose rayon fabrics coated with chitosan-encapsulated iodine: antibacterial and antioxidant properties
(Sage Publications Ltd, London, 2018)
Adsorption of chitosan nanoparticles with embedded iodine was implemented onto pristine and oxidized cellulose viscose fabrics in order to introduce antimicrobial and antioxidative functionalization. The adsorption capacity, ...
Risk maps for industrial occupational health and safety / Mape rizika za zdravlje i bezbednost na radu u industriji
(Univerzitet u Nišu, Niš, 2016)
Risk assessment is a complex process, of which the outputs are often to be used by decision makers for policy development and risk management. Risk communication in Environmental sciences is often made simpler using risk ...
Synthesis of 5-(substituted phenylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones from ethyl 3-oxo-2-(substituted phenylazo)butanoates / Sinteza 5-(supstituisanih fenilazo)-6-hidroksi-4-metil-3-cijano-2-piridona iz etil-3-okso-2-(supstituisanih fenilazo)butanoata
(Serbian Chemical Society, Belgrade, 2011)
A new procedure for the synthesis of known azo pyridone dyes is presented. A series of 5-(substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones were prepared from ethyl 3-oxo-2-(substituted phenylazo)butanoates and ...
