Bacterial diversity in typical abandoned multi-contaminated nonferrous metal(loid) tailings during natural attenuation
(Elsevier, 2019)
Abandoned nonferrous metal(loid) tailings sites are anthropogenic, and represent unique and extreme ecological niches for microbial communities. Tailings contain elevated and toxic content of metal(loid)s that had negative ...
Modified eggshell catalyst for transesterification of sunflower oil: The effects of catalyst loading on FAMEs content
(Belgrade : Serbian Chemical Society, 2019)
Modified highly active CaO catalyst (ESCHC-600) derived from waste chicken eggshells were prepared and used in the transesterification of sunflower oil. Eggshells were subjected to calcination-hydration-calcination (CHC) ...
Biodiesel synthesis over green catalyst: The effect of thermal treatment of CaO/Zeolite precursor on catalytic activity
(Belgrade : Serbian Chemical Society, 2019)
The green CaO/Zeolite catalyst for methanolysis of fatty oils was synthesized entirely from the waste materials. CaO derived from chicken eggshell was loaded onto fly ashbased zeolite catalyst carrier by the wet impregnation ...
Interactive Catalytic Performances of Carbonaceous Materials in Electrochemistry
(New York, USA : Nova Science Publishers Inc., 2019)
The attraction of carbon as an electrode material arises from its unique chemical and physical properties: high conductivity, good corrosion resistance, high temperature stability, high surface-area range (∼1 to >2000 m2 ...
Modelling the use of Industry 4.0 technologies with lean manufacturing
(Zrenjanin, Serbia : University of Novi Sad, Technical Faculty "Mihajlo Pupin", 2019)
The lean manufacturing approach has the potential to lower production costs and increase productivity through the reduction of various forms of waste. It is evident that lean manufacturing as a business model offers stable ...
Evolution of Si Crystallographic Planes-Etching of Square and Circle Patterns in 25 wt % TMAH
(MDPI, 2019)
Squares and circles are basic patterns for most mask designs of silicon microdevices. Evolution of etched Si crystallographic planes defined by square and circle patterns in the masking layer is presented and analyzed in ...

The genus Neidiopsis is small comprising eight known taxa distributed in oligotrophic to dystrophic freshwater habitats.
During observations of diatoms from alpine intermittent ponds on the Shara Mountain, Republic of ...
The Investigation of Characteristics and Thermal Behaviour of Lignocellulosic Waste Biomass Using Thermogravimetric Analysis
(Bosnia and Herzegovina : University of East Sarajevo, Faculty of Technology, 2019)
This paper focuses on lignocellulosic waste biomass originating from food industry, which should find its further application in order to fulfill demands of circular economy. Therefore, here are presented some of the ...
The Spatial Patterns of Red Beds and Danxia Landforms: Implication for the formation factors–China
(Springer Nature Publishing AG, 2019)
This research examined the distribution features of red beds and 1,100 Danxia landform sites across
China, while probing the relationship between these spatial patterns and geological elements. This
study is based on ...
Land degradation and management of red beds in China: Two case studies
(Springer Science and Business Media LLC, 2019)
Red beds cover approximately 9.5% of China, and are home to approximately 144 million people. In total, 83% of these lands are distributed in humid regions making it an important part of research on red bed soil erosion ...
