Abstract Per- and polyfluoroalkyl substances (PFAS) and microplastics (MPs) are certain types of persistent plastic contaminants that are a cause of concern to both the ecosystems and human health. The nanotechnologies o...

The 1-heptyne selective hydrogenation carried out at 150kPa, and at 283 and 303K using Ru/Al2O3 and Ru/C as catalysts, was studied. Catalysts were prepared by the incipient wetness impregnation technique using RuCl3 as p...

In the current study, the chemical composition of Baccharis spicata (Lam.) Baill. and B. punctulata DC., Asteraceae, aerial parts’ volatile oils were analysed. A higher proportion of monoterpenes than sesquiterpenes wa...

The aim of this study was to characterize Pd catalysts supported on three different mordenite zeolites (a commercial sample and two laboratory preparations) previously tested for the NO decomposition reaction. H2 chemiso...

Abstract The dual challenges of waste biomass disposal and escalating contamination by inorganic, organic, and emerging microplastic pollutants demand sustainable, circular remediation strategies. Biochar, a carbon-rich,...

Abstract Sensitive and accurate detection of biologically significant bilirubin is of great importance in the field of clinical diagnostics and disease monitoring. The present study introduces the TX-100 based nanomicell...

Natural gas is a cleaner fuel for combustion and with less carbon intensity than traditional ones (gasoline and diesel); however, it requires an adequate calibration of the electronic management of the internal combustio...

Abstract Three chromophores 5a-c based on the diphenylamine (donor), thiazole (π-core) and acrylonitrile (acceptor) were synthesized and characterized by IR, NMR, MS analyses. The donor–acceptor chromophores 5a-c were...

Background It is well known that fish predation alters ecosystem processes by top-down effects. Salmonids are described as aggressive, visually and size-selective predators. Thus, prey selection by the non-native rainbo...

Abstract Diabetes mellitus represents one of the most prevalent chronic diseases worldwide, posing serious challenges to global health and healthcare sustainability. Conventional therapeutic strategies often face limitat...

Recently, a three dimensional metal-organic framework (MOF) based on Dy(III) and the L-tartrate ligand was experimentally shown to exhibit a spin polarization (SP) power of 100% at room temperature. The material’s spin...

In this article we describe the application of lipases in acylation and alcoholysis reactions on steroids and nucleosides. In the field of steroids, a variety of acetyl and fatty acid derivatives of androstanes, pregnane...
