Radon and thoron exhalation rate measurements from building materials used in Serbia
(Nukleonika, 2020)
The second most important source of indoor radon, after soil beneath dwelling, is building material. With the increase in environmental awareness and new energy-saving policies, residents tend to replace the existing windows ...
Mechanical features of copper coatings electrodeposited by the pulsating current (PC) regime on Si(111) substrate
(Electrochemical Science Group, Beograd, 2020)
Mechanical features of the Cu coatings produced by the pulsating current (PC) regime on Si(111) substrate have been investigated. The Cu coatings were electrodeposited by varying duty cycle (15-50 %) and keeping the current ...
Pipe size sensitivity in pressure relief networks using genetic algorithms
(Hemijska industrija, 2020)
This paper utilizes a stochastic optimization approach using genetic algorithms, for conducting rigorous pipe size sensitivity assessments onto the design of pressure relief networks. By sampling high performance candidates, ...
Design of biopolymer carriers enriched with natural emulsifiers for improved controlled release of thyme essential oil
(Wiley, Hoboken, 2020)
This work aims to characterize a novel system for thyme essential oil delivery based on the combination of natural emulsifiers (soy protein and soy lecithin) and alginate, produced using the extrusion technique. The ...
Corrosion of stainless steel 316Ti tank for the transport 12-15% of hypochlorite solution
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The corrosion of the transport tank materials made of stainless steel 316Ti is investigated in a solution containing 12-15% of the commercial sodium hypochlorite solution. Using the electrochemical techniques, weight loss ...
Valorization of walnut shell ash as a catalyst for biodiesel production
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, Ny physisorption, SEM, and ...
Removal of Acid Textile Dye from the Aqueous Solution by a New Adsorbent Obtained from Waste Cotton from the Garment Plant
(Chem Soc Pakistan, Karachi, 2020)
The paper investigates the possibility of removing acid dye from the aqueous solution by an adsorption process on new adsorbent prepared from waste cotton textile from the ready-made garment industry. It is a waste generated ...
A CaO/zeolite-based catalyst obtained from waste chicken eggshell and coal fly ash for biodiesel production
(Elsevier Sci Ltd, Oxford, 2020)
The present paper is focused on the development of a new environment-friendly methanolysis catalyst completely based on waste materials: lignite coal fly ash and chicken eggshells. A novel catalyst based on CaO supported ...
Lead isotope ratios as tool for elucidation of chemical environment in a system of Macrolepiota procera (Scop.) Singer - soil
(Springer Nature, 2020)
The analysis of isotope ratios of lead in the mushrooms and soil, where they were grown, assisted with a principal component analysis, offered a new perspective for understanding possible chemical environment in a real ...
Mechanical Oscillations in 2D Collective Cell Migration: The Elastic Turbulence
(Frontiers Media Sa, Lausanne, 2020)
Various types of mechanical waves, such as propagative waves and standing waves, are observed during 2D collective cell migration. Propagative waves are generated during monolayer free expansion, whereas standing waves are ...
