Summary: This study reported a gas sensor based on Pr-doped ZnO nanospindles for the detection of triethylamine (TEA). Among the different doping concentrations, the 2 mmol% Pr-ZnO sensor exhibited the highest response value towards TEA gas. The sensor showed good reproducibility, rapid response/recovery time, theoretical limit of detection, outstanding long-term stability, and excellent selectivity for TEA gas.

Summary: We developed a one-pot Bunte's reaction platform under aqueous conditions for the efficient conversion of sulfonylureas to synthetically versatile thio-sulfonylureas. The reaction can also yield diverse chiral and achiral isothiosulfonyl analogs. This protocol enables the synthesis of various drug-like molecules and was applied to the enantiomeric synthesis of a cannabinoid receptor antagonist SLV326.

Summary: In this study, zinc ferrite nanoparticles were synthesized in the presence of lemon juice and characterized using various techniques. These nanoparticles were then used as nanocatalysts for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives. This green synthetic approach offers important advantages such as the use of non-toxic substances and high yields in a short reaction time.

Summary: Polysorbate 80 (PS80) was reacted with 3-mercaptopropyl trimethoxysilane (SiSH) via a photoinitiated thiol-ene reaction to obtain thiol-functional nanoparticles. These nanoparticles have a high number of thiol residues per particle, allowing for easy modification of particle properties. When added to 3D printing resin, the thiol-functional nanoparticles significantly enhance the curing rate.
