A diamine monomer containing an ether group can reduce the friction coefficient and improve the wear performance of PAI material, and the wear mechanism of the PAI material can also change due to ether linkages.

Enantiomerically enriched or homochiral cis-1,2-dihydrocatechols such as 10 have been elaborated via their Diels–Alder adducts (e.g. 20) and then the corresponding sulfites (e.g. 21 and 22) into the title compounds 23.

A novel method is described, using perruthenate salts, for performing the rarely reported dehydrogenation of primary alcohols to afford unsaturated aldehydes in low to moderate yields. The discovery, method development, reaction scope, and associated challenges of this method are presented in detail.

In this article, the pK_as of seven phospholes were determined theoretically. The major challenge in their determination is that the experimental pK_as of all the seven phospholes are not reported in the literature. We are the first ones to endeavour to calculate their pK_as.

We developed a simple and selective fluorescent aptasensor for the detection of oxytetracycline (OTC) using aptamer-conjugated gold nanoparticles (AuNPs) and a complex formed between oxytetracycline and a europium cation. In this study, AuNPs were modified with an OTC aptamer using two methods (Tween and NaCl methods).

A new Cs-γ-CD-MOF material was synthesised by an improved gas vapour diffusion method. The adsorption capacity of γ-CD (142.92 mg g⁻¹) and Cs-γ-CD-MOFs (280.05 mg g⁻¹) for myricetin was compared. The energy and conformation of the adsorption of myricetin on Cs-γ-CD-MOFs were obtained by molecular docking.

Secondary structure in peptides, such as helices, can be stabilized by introduction of a bimane group. This inherently fluorescent group simultaneously provides a tag to monitor the resulting peptidomimetic in biological assays.
