Noncovalent carbon bonding (C-bonding), a recently explored σ-hole interaction, has primarily been characterized through X-ray structural and computational studies. Evidence of C-bonds in solution is scarce, especially in highly polar solvents like DMSO where solvation effects typically overshadow weak non-covalent interactions. In this work, we present three novel spiroisatin-based -acyl hydrazones (1-3) in which C-bonds play a critical role in stabilizing the conformation in solution.

Wood modification using low molecular weight thermosetting resins improves the biological durability and dimensional stability of wood while avoiding increasingly regulated biocides. During the modification process, resin monomers diffuse from the cell lumen to the cell wall, occupying micropore spaces before curing at 150 °C. This study investigated the mechanism of cell wall diffusion at multiple scales, comparing two test groups where diffusion was either facilitated or restricted.

Water-lean absorbents are regarded as a new generation of post-combustion CO2 capture technology that could significantly relieve those drawbacks posed by traditional aqueous alkanolamines. However, the exponential increase in viscosity during CO2 absorption remains an urgent issue that needs to be resolved before their practical deployment. In this work, novel water-lean amines based on biomass glycerol have been devised as single-component CO2 absorbents with low viscosity (79~110 cP at 25 oC, 29~39 cP at 40 oC) under high capacity (12~18 wt% at 25 oC, 10~17 wt% at 40 oC).

In recent years, Imidazothiazole-Chalcone conjugates have emerged as notable pharmacophores with potential applications in discovering biologically active compounds. This study focuses on synthesizing novel imidazo[2,1-b]thiazole chalcone derivatives through a facile and conventional process adhering to several principles of green chemistry, facilitating scalable production. The synthesized compounds underwent comprehensive spectroscopic analysis, including 1H NMR, 13C NMR, LC-MS, and FT-IR techniques.
