Solvent attenuation of dispersion interactions was quantified using a new class of rigid intramolecular CH-π molecular balances. These balances incorporate small, two-carbon CH donors that minimize solvophobic effects and isolate the dispersion component. Folding energies (Δ ) were measured across eight solvents: cyclohexane, toluene, chloroform, ethyl acetate, acetone, acetonitrile, DMSO, and methanol.

An unprecedented recyclable system of copper-catalyzed C-C/N coupling of isatins and DMSO without any oxidant and acidic/basic additive has been unlocked. The -isatins occur tandem -methylation and C5-methylthiomethylation in order, while -substituted isatins proceed C5-methylthiomethylation only. DMSO serves as Me and MeSCH sources as well as the solvent.

Despite advancements in bonding techniques, the resin-dentin interface remains the weakest point in dental restorations, susceptible to collagen degradation and methacrylate hydrolysis. One strategy to enhance the resin-dentin interface is to incorporate hydrogen-bonding-rich functional groups into dental adhesive resins, such as 2-ureido-4[1H]-pyrimidinone (UPy). These hydrogen bonds may bridge the adhesive resin and dentin substrate, which contains collagen and hydroxyapatite, as well as form non-covalent crosslinks within the resin.

Background: Graphene, with its unique electronic, thermal, and mechanical properties, plays an important role in electronic devices and batteries. Current applications strongly rely on liquid-phase processing, which requires stable graphene dispersions. However, stabilizing graphene dispersions in a liquid phase remains challenging because graphene easily aggregates due to strong inter-sheet forces.

Vast majority of hydrogels are at risk of being frozen, which severely limits their applications in many fields. There are numerous methods for preparing gels with antifreezing properties. This paper puts forward a special method to improve the antifreezing property of gels by adjusting the ratio of polymer monomers.
