Noncovalent decoration of carbon nanotubes (CNT) with pentacyanoferrate(II)-containing polymer is reported in order to obtain a solution-processable multifunctional material.

Copper-doped silica cuprous sulfate is a powerful and highly efficient nano-catalyst for synthesis of structurally diverse 5-substituted 1H-tetrazoles.

Five new sesquiterpenoids were isolated from the essential oil of the leaves of Nectandra megapotamica (Lauraceae). Their structures were elucidated by spectroscopic analysis, and the relative configurations were proposed by their nuclear Overhauser effect (NOESY) spectrum. Three compounds displayed significant antimicrobial activity.

Andean tomato landraces from Northwestern and Cuyo regions of Argentina were analyzed by their volatile composition for the first time by headspace solid phase microextraction coupled to gas chromatography-mass spectrometry (HS-SPME-GC-MS).

Particle morphology with wormhole pore channels and oxidation of benzene, toluene and o-xylene to CO₂ and H₂O promoted by MS-Ga7% catalyst.

Gold electrodeposit as modifier enhance the carbon paste electrode (CPE) performance on the ferro/ferricyanide reversibility.

Uniform Te nanowires with diameter below 30 nm and length up to 5 µm were prepared via facile surfactant-assisted synthesis under mild conditions. Notably, short and long Te nanowires show a switching behavior from saturated absorption to reverse saturated absorption as a function of laser intensity.

Simplified representation of the transport mechanism of Ag⁺ ions across bulk liquid membrane.

The misuse of antibiotics in animal husbandry can result in unsafe foodstuff, hence the need of new methods for determining such residues.

The [CuCl(L1)(phen)].0.5H₂O and [CuCl(L2)(phen)].2H₂O complexes presented cytostatic effect and complex [CuCl(L1)(phen)].0.5H₂O also showed in vitro trypanocidal activity. Both complexes were able to binding to deoxyribonucleic acid (DNA) and albumins.

The concentrations of As, Cr, Cu, Ni, Pb and V in acyclovir ointment and their manufacturer products were determined using an inductively coupled plasma-universal cell technology-mass spectrometer (ICP-UCT-MS) operated in standard and kinetic energy discrimination (KED) modes, employing a single microwave acidic digestion (MW-AD) for all samples.

AgNPs-based ZHL hybrids were synthesized via a facile and rapid one-pot green process. The reduction from Ag⁺ ions to Ag⁰ was assisted by visible-light. AgNPs were supported on the external surfaces of ZHL. AgNPs/ZHL is an active, stable and reusable catalyst for 4-nitrophenol reduction.

The various positions adopted by 6CN10 in 2-hydroxypropyl-β-cyclodextrin complex obtained through the docking study. Among the six lowest energy positions, in five different poses the 6CN10 is over the cyclodextrin cavity but not inside.

Formulated microparticles with lignins may contribute to the development of green formulations of natural insecticides increasing their thermal and photo stability. Lignin microcapsules loaded with natural products were evaluated against Spodoptera frugiperda and Diatraea saccharalis.

Main fragmentation routes for rhodamines B and 6G were investigated by high accuracy Orbitrap MS/MS.

Aquatic colloids (1 nm-1 µm) conditioning metals availability to the biota in the water column as a function of their chemical structure and composition.

A new erythroxylane diterpene, named angelocunhol, was characterized together with 14 known compounds from the Simira sampaioana (Rubiaceae) wood.

This paper is part of the PubliSBQ Special Issue in honor of the late Prof Angelo da Cunha Pinto.

Adsorption and desorption are important processes that influence the transport, transformation and bioavailability of antimicrobials in soils.

Ag doping and addition of cetyltrimethylammonium bromide (CTAB) which provides more active sites for the pseudocapacitive reactions.

SLE-LTP: simple, easy and efficient low temperature purification.

The three-dimensional anode of PbO₂ electrodeposited on a reticulated vitreous carbon (RVC) substrate demonstrated superior electrooxidation performance for dye decolorization compared to flat plate electrode (VC/PbO₂).

Glucose concentration levels have been colorimetrically determined in biological fluids using toner-based microzone plates.
