Comparison of Particle Shape, Surface Area, and Color Properties of the Calcite Particles Ground by Stirred and Ball Mill
(2023)
Since the particle size, shape, specific surface area, and purity of the ground calcium carbonate (GCC) decide its usability in the paper, paint, and plastic industries, the effect of grinding is important. However, the ...
Advanced Green and Sustainable Chemical and Physical Technologies for Resources Recycling of Solid Wastes
(Frontiers Media SA, 2 Mart 202)
To prevent CO2-induced climate change, the world is quickly moving toward a carbon- neutral society by using electric vehicles, renewable energy sources, and other energy sources, which demand more resources than traditional ...
Optimization of Paracetamol and Chloramphenicol Removal by Novel Activated Carbon Derived from Sawdust Using Response Surface Methodology
(01.02.2023)
Paracetamol (PCT) and chloramphenicol (CPL) can have unfavorable impacts on human health, as well as on natural ecosystems. These substances contribute to the aquatic environment’s contamination and disturb the performance ...
Investigation of structural, morphology, and conduction mechanism of GO–Fe3O4–TiO2 composite material
(23.08.2023)
The graphene oxide composite (GO), iron oxide (Fe3O4), and titanium dioxide
(TiO2) were prepared by the sol–gel process. The surface of GO is coated with
TiO2 and Fe3O4 nanoparticles, and the composite contains 10.26% ...
Synthesis and characterization of molybdenum trioxide with an orthorhombic crystal structure for supercritical water gasification application
(01.03.2023)
Supercritical water (SCW) catalytic gasification is promising for the production of synthetic gas from biomass. However, maintaining the activity of heterogeneous catalysts under high pressure and hydrothermal conditions ...
Evaluation of characteristics of raw tea waste‑derived adsorbents for removal of metals from aqueous medium
