An oxazinoquinoxaline as corrosion inhibitor for mild steel in saline medium.

The importance of the in vitro phytoremediation method study to evaluate the process of removal of pollutants.

A new RP-HPLC method was developed and validated for the simultaneous determination of antiparasitics. In addition, FTIR (experimental and theoretical), TGA, and SEM were useful to identify the raw materials.

Photocatalytic behavior of ZnO (○) and TiO2 (□) in the decolorization rate constant, kobs, of methyl orange (▬); acid orange 7 (▬); direct orange34 (▬); and direct yellow 86 (▬) at 30 ºC.

Microparticles of PLA100 containing 0.75 wt/v% of PVA with cardanol encapsulated.

The biodiesel yield doubled using lipase mixture in ethanolysis of acid oil. The blend of Lipozyme TL and Novozym was the best option considering cost and yield. Lipases can be used to produce biodiesel from oils high levels acidity oils.

Marine sponges synthesize several metabolites with potential biological activities. The large pharmaceutical companies have initiated programs for the application of these metabolites in medicine.

Isoquinoline alkaloids with high polarity from Phellodendri Cortex, were successfully separated by PZRCCC with a two-phase solvent system chloroform/methanol/water (4:2:2, v/v).

Oviposition of Leucoptera coffeella was prevented by the extract of Merremia tomentosa and two of its components, ursolic acid and cis-tiliroside. In silico studies suggest that these substances act against the insect by inhibiting the enzymes glycogen phosphorylase and xanthine dehydrogenase.

Molecular representation of solid HMX unit cell, with molecules distributed inside the boundaries, prior to the material ignition.

Since 1991 sensitized photocatalysts has been a hot topic in many research fields, especially in heterogeneous photocatalysis. In the last five years, conducting polymers has been consolidated as a novel class of photosensitizers.

Comparison between monocrystal n-dopped and nanoparticle semiconductor electrodes and their respective band diagrams both under a positive biasing potential (V_Bias > V_FB). The model considered for the space-charge layer (SCL) is the depletion layer and the Flat Band.

Treatment of a Cr(VI) residual solution with a given amount of commercial steel wool pads followed by chemical precipitation with NaOH up to pH 10-11 and separation by filtration under reduced pressure. The produced solid residue is predominantly Cr(OH)₃ and Fe(OH)₃.

Didactic experiment based on the combination of Near Infrared Spectroscopy and Multivariate Curve Resolution to create a chemical imaging of pharmaceutical pellets to obtained the special distribution and spectral profile of each component in the system.

For extraction of limonene, the steam distillation presents better overall greenness (green star metric) and higher throughput, but some other specific metrics indicate that extraction by solvents is greener.
