Synthesis of new alkyl phenyl polyglycosides from cardol and the anacardic acid through a green synthetic route.

PHA-producing bacteria isolated from the environment was better characterized when submitted to a polyphasic screening, in addition to their biochemical profile in miniaturized galleries such as API 20E^® and amplification of genes.

Guanine to carcinogen electron transfer mechanism: according to the unsynchronized resonating valence bond theory of L. Pauling, an electron transfer leads to formation of a covalent bond between DNA (guanine) and the carcinogen (PAH).

Molecular distillation is a clean technology that separates compounds in fractions of seconds. This process allowed for recovery of sesquiterpenes from copaiba oil-resin with 98% purity.

Specimens of nitrile rubber vulcanized with novel tin (IV) accelerators [R = C₆H₅; ClC₆H₄; BrC₆H₄ and IC₆H₄] for tensile strength and tear resistance analyses.

Second Harmonic Generation (SHG) at the 1653 nm of the P3m1 phase for the BC₅ cluster.

New global and local reactivity descriptors have been developed in basis to canonical and grand canonical ensembles of conceptual DFT. All of reactivity indices showed a good description of both local and global reactivity trends on the selected molecules.

Ten substituted pyrazolone derivatives were easily synthesized from perfluorinated allylic alcohols, via a straightforward two steps reaction involving a Heckcoupling/isomerization reaction and subsequent condensation of hydrazines.

F⁻-sensing properties of a calix[4]pyrrole boradiazaindacene dye were evaluated with respect to the effects of the presence of different tetraalkylammonium cations in CH₃CN. The dye exhibited F⁻-binding affinity in the order K_TMA+ > K_TEA+ > K_TBA+ as a consequence of cation size effects and ion-pairing effects.

Tests were carried out to select the best solid support (granular activated carbon - GAC, crushed ceramic material - CCM, and zeolite - ZEO) and procedure (dip and coat, sol-gel) for TiO₂ immobilization for their use in the photocatalysis of sulfamethoxazole (SMX) in aqueous solutions.

Polyaniline-silica composites were synthesized using different mesoporous silica hosts. The synthesis pathway allowed a faster polymerization, high polymerization efficiency and higher molecular weights than for other polyaniline derivatives synthesized without the use of hosts. The high surface area of the silica favored the adsorption of aniline and the presence of aluminium on them accelerated the polymerization process. Therefore, the hosts had dual properties as nucleation centers and catalysts in this process. The composites were electrical conductive materials.

Prediction of photoelectric conversion efficiency of derivatives D-NPR-A and D-NTP-A.

Water classification based on digital images. Waters are combined with colorimetric reagents, the RGB parameters are acquired with a smartphone and discrimination is performed using raw data.

Transmission and reflection coefficients calculated by the variable amplitude method.

What is an inverse problem and how to extract the maximum information from experimental data, such as the potential energy function from second virial coefficient, is the main objective of the present paper.
