The transformation of by-products of processes is of interest for the increase of the efficiency. In addition, the concept of sustainability applied to recovery processes allows retaining a product within a supply chain, giving a longer useful life to available resources. The concepts of exergy complementing the emergy concept, allows to have a broader prospect in the evaluation of processes. In this research, both concepts are applied to the use of residual biomass from a WWTP through gasification, where the recovery of all the streams involved is shown.

The present study explored a simple and economical method for analyzing ketoconazole from the complex cream formulation by utilizing the green solvent with zero wastage and made the method more sustainable and easily adaptable for future use.

Leaching of spent pre-oxidized NiMo/Al₂O₃ catalysts from ultra-deep hydrodesulfurization units in the presence of HF + H₂O₂ mixtures: recovery of the fluoride ion and valuable elements.

In Inceptisol, organic carbon stabilization can be facilitated by hydrophobic interactions, whereas in Mollisol, different interaction sites can stabilize like proteinaceous compounds.

A novel fluorescence sensor for the detection of chloride ion was designed with Nitrogen-doped graphene quantum dots.

The increase in the antiviral performance of this compound is further maximized by formulating TiO₂-based composites and doping it to reduce the bandgap. This review aims to determine the challenges of TiO₂-based composite as a visible active photocatalyst material for SARS-CoV-2 antiviral.

This paper is a literature review covering the last 10 years on research with Ag(I) complexes that showed activity against the tuberculosis bacillus.

A test mixture was developed and applied to LC-MS untargeted metabolomics. Its use quickly indicated column degradation during sample analysis and that only visual inspection of pooled QC clustering in PCA does not guarantee reliable data.

Dip-coater machine to produce high quality thin films.

Cooperative and collaborative learning in the chemistry classroom.

Easily obtained from black beans, a natural pH indicator can be used to determine the acidity or basicity of aqueous solutions. The indicator had its pKa values determined and was also impregnated with paper and cotton for greater practicality.

The role of chemistry in COVID-19 pandemic is highlighted through the medical oxygen utility in health, oxygen chemical characterization and its cycle in nature, industrial production, and how oxygen saturation level in blood is measured.

A PLS model using FTIR spectroscopy to predict the concentration of the chemical species of CO₂ absorption/desorption process in aqueous amine solutions.
