Synthesis of Quercetin derivative, UV analysis, FPS calculation, photo stability and incorporation in a sun protection formulation.

A method was developed and validated for evaluation of different species and geographical origins using targeted quantitative analysis and non-targeted FT-IR spectroscopy.

Differences in average composition of freebase cocaine and hydrochloride cocaine, showing that hydrochloride cocaine seized in the state of Rio de Janeiro is majorly composed of non-active compounds (diluents), while freebase cocaine is majorly composed of active compounds.

The amount and variety of foreign elements deposited on NiMo/Al₂O₃ catalysts increased and coke became more aromatic in the most recent generations as expected from the more drastic HDS conditions and the quality of the crude diesel.

A heteropolysaccharide with a main chain composed by β-D-galactofuranosidic units (1→5) and (1→6) linked with residues α-D-glupiranosidic as a branch was isolated from C. gloeosporioides biomass. It did not present cytotoxic activity on CHO-K1 cells.

A novel supramolecular helicate [Fe^II₂L₃]⁴⁺ from subcomponent self-assembly is subject to bind electron-rich aromatic pyrene guests via aromatic π–π interactions.

Effective use of the Fenton-adsorption process to degrade the BPA molecule in landfill leachates.

This tutorial review presents, in a concise way, a general and contemporary view of the rise of Enantioselective Organocatalysis in the Asymmetric Catalysis, following the evolution of the area from its versatile generic modes of catalyst activation.

The figure shows the automatized method to determine the PSD of nanosphere by SEM. The results show that the method was well succeeded. In addition, Au and C deposition produce a thinner layer that affect the morphology, thus influenced the particle size.

Hydrogen evolution reaction on copper cathode in sulfuric acid solution by electrolysis.

Authorship in a virtual learning environment with the participation of undergraduate chemistry students.

By showing the real elements in the Periodic Table, one can better envision their identities and characteristics, inviting us to access this wonderful Chemistry Portal.
