In this work, the salting-out strength of reline eutectic mixture in aqueous solution non-ionic surfactant Triton X-102 has been demonstrated at temperatures between 298.15 and 323.15 K as a preliminary step to be employed downstream operations biotechnological process. The phase diagrams data reline-based Aqueous Two Phase Systems (ATPS) have correlated using empirical models based on exponential polynomial equations. tie-lines empirically ascertained through physical properties characterization Othmer-Tobias equation was proposed correlate those data. After having studied effect two model enzymes (protease lipase), performance ATPS for selectively separating them evaluated three different feed compositions same tie-line, demonstrating their pertinence segregate lipase one phases (yield about 95 %) protease other 98 %). These promising results are interesting application reactions where proteases proved deleterious lipases activity, biocompatibility platform does not involve drastic negative effects any enzymes.

The growing need for oil presents a difficulty necessitates finding alternative energy sources. Since petroleum is non-renewable resource, it requires millions, or even hundreds of millions years to undergo transformation its raw materials into usable petroleum, the increase in amount consumption causes depletion potentially causing an crisis future. One solution process waste cooking biodiesel as substitute diesel fuel. In order generate superior with relatively elevated quality, investigation was conducted on use CaO purifier from impurities, separating glycerol and methyl ester. Most interestingly, Biodiesel can be used existing engines minimal no adjustments little loss performance. studies suggest that incorporating sufficient oxygen significantly reduces exhaust emissions.

Over the past few decades, peroxymonosulfate (PMS)-driven advanced oxidation processes (AOPs) have garnered substantial interest in field of organic decontamination. The copper (Cu)/PMS system is intriguing due to its diverse activation pathways and has been extensively employed for clearance refractory pollutants water. This article designed offer a comprehensive overview latest trends Cu-based catalysts such as single-metal mixed-metal aimed at treating recalcitrant pollutants, highlighting PMS activation. Subsequently, investigative methodologies assessing with copper-based are reviewed summarized. Then, implications pH, catalytic agent concentrations, anions, natural matter also addressed. combination catalyst/PMS systems other technologies discussed. Following that, degradation mechanisms catalyst-activated considered synopsized. Lastly, potential future research avenues proposed enhance technology support developing economically viable materials based on activating PMS.
