in order to reduce the operating temperature of solid oxide fuel cells (sofcs), novel electrolyte materials based on ceo2 and baceo3 are being developed in the scientific realm. in this context, we propose a new methodology for preparing the nano-ceramic composite materials such as bace0.9gd0.9o3-δ – ce0.9gd0.9o2-δ (bcgo–cgo) and bace0.8sm0.2o3-δ – ce0.8sm0.2o2-δ (bcso – cso) as possible elec...

In this study, the potential antimicrobial activity of plasma-activated tap water (PAW) was evaluated against Staphylococcus aureus, Escherichia coli, and Candida albicans. For this, PAW prepared in a gliding arc plasma system using two treatment conditions: stagnant stirring by magnetic stirrer, called moving water. Subsequently, their oxidation-reduction (ORP), pH, electrical conductivity (?)...

In the present investigation, we report that statistical design and optimization of significant variables for the microbial production of citric acid from sucrose in presence of filamentous fungi A. niger NCIM 705. Various combinations of experiments were designed with Central Composite Design (CCD) of Response Surface Methodology (RSM) for the production of citric acid as a function of six var...

Building a mathematical model of the polymerization reactor is necessary to determine dependencies between input variables, technological mode and output variables ethylene process in an autoclave with stirrer, as well analyze effect design parameters on efficiency. A deterministic developed basis analysis physico-chemical regularities proposed solve these problems. There shown schematic diagra...

Nickel oxide NPs are widely recognized as excellent photocatalysts due to their unique optical features such bandgap energy, retention time, strong light absorption, electron-hole recombination duration, and significant negative oxidation potential of excited electrons. NiO nanoparticles were successfully created using a combination nickel hexahydrate precursor, ethanol, distilled water. was em...

This present work aims at synthesizing sodium silicate solutions from selected industrial wastes (waste glass and rice husks) using hydrothermal method. The as-received waste glasses of different mix colors were initially washed, crushed wet milled for several hours then sieved through 75µm mesh. recycled oven dried 110oC 72 h to obtain a powdered (SLSG). Rice husks also washed remove dirt adhe...

This work was aimed at; investigating a clean method of removing waste leaves from the stream, converting them into fatty acids, biodiesel feedstock, or upgrading to deoxygenated fuels for higher energy content. Waste Gmelina arborea were collected, cleaned, and pulverized with ceramic mortar pestle. A 50g thermally hydrolyzed over 0.75g H2SO4, NaOH, ZnCl2 catalysts 500mL distilled water on Gal...
