Organocalcogenides, in particular, organoselenium compounds, have been widely studied due to their large number of synthetic and biological applications. Among organoselenium compounds, a class of bis-selenide-alkene derivatives has attracted attenti...

We established a new visible-light-mediated protocol for the regioselective β-hydroxyselenylation of olefins, employing benzeneseleninic acid as substrate. Regarding a novel approach, the benzeneseleninic acid emerges as an efficient and afforda...

Chagas disease, considered by the World Health Organization as a neglected tropical disease, is responsible for the deaths of more than 10,000 people annually. The main drugs used to overcome the disease, Benzonidazole and Nifurtimox, besides being o...

In this work, FeM composites consisting of montmorillonite and variable amounts of Fe3O4 were successfully synthesized via a facile co-precipitation process. They were characterized using X-ray photoelectron spectroscopy (XPS), field emission scannin...

Plastic waste poses an enormous environmental problem as a result of soil and ocean contamination, causing the release of microplastics that end up in humans through the food web. Enzymatic degradation of plastics has emerged as an alternative to tra...

In this work, acidic ion-exchange resins with strong Brönsted sulphonic groups were assessed in the catalytic etherification of the platform molecule 5-(hydroxymethyl)furfural (HMF) to 5-(ethoxymethyl)furfural (EMF), a biofuel with an energy den...

This paper presents graphite/paraffin composite electrodes modified with microparticles of nickel (Ni) and Ni-Fe alloy anchored in reduced graphene oxide (rGO); these electrodes were made by electrosynthesis. Firstly, the electrodeposition of reduced...

In this work, Pt-Ni/CeO2-SiO2, as well as Ru-Ni/CeO2-SiO2 catalysts, were obtained at different loadings of the noble metal (in the interval 0–3 wt%) and tested for oxidative steam reforming of ethanol. Stability performance was evaluated at 50...

Immobilized enzymes are the most sought-after preparations in the global market. They are used in medicine, veterinary medicine, the food industry, winemaking and brewing. The simplest method for immobilizing biocatalysts on insoluble carriers is the...

Thermotoga maritima beta-fructosidases are enzymes that release beta-D-fructose from sucrose, raffinose, and fructan polymers such as inulin. The surfaces of beta-fructosidases 1UYP and 1W2T from Thermotoga maritima were studied in this work. It was...
