D-Xylose-based ionic liquids have been prepared from D-xylose following a five steps reaction sequence, the key step being a click cycloaddition. These ionic liquids (ILs) have been characterized through classical analytical methods (IR, NMR, mass spectroscopy, elemental analysis) and their stability constants, Tg and Tdec, were also determined. Considering their properties and their hydrophilicity, these compounds could be alternative solvents for chemical applications under mild conditions.

The development of intelligent nanotheranostic technology that integrates diagnostic and therapeutic functions holds great promise for personalized nanomedicine. However, most of the nanotheranostic agents exhibit "always-on" properties and do not involve an amplification step, which may largely limit imaging contrast and restrict therapeutic efficacy. Herein, we construct a novel nanotheranostic platform (Hemin/DHPs/PDA@CuS nanocomposite) by assembling DNA hairpin probes (DHPs) and hemin on the surface of PDA@CuS nanosheets that enables amplified fluorescence imaging and activatable chemodynamic therapy (CDT) of tumors.

The formation of gastric precancerous-lesions (GPLs) has been identified as a critical step in tumorigenesis, and patients with GPLs have an increased risk of gastric cancer. Magnolol is the primary biphenolic compound in Magnolia officinalis. It possesses various pharmacological properties, such as cardioprotective and neuroprotective properties, and inhibit tumor growth.

This study proposes a green and efficient atom- and step-economical method for converting hazardous CS to dithiocarbamate derivatives under visible light irradiation and catalyst-free conditions. By the construction of novel C-S and C-N bonds, a series of β-dicarbonyl compounds and amines are incorporated into the products. Under light, CS and amine first form bis(dialkylaminethiocarbonyl)disulfides, which then react with KCO-activated β-dicarbonyl compounds to form electron donor-acceptor (EDA) complexes and subsequently generate the target products.

Simultaneously hydrophilic and oleophobic surfaces offer substantial advantages for applications such as antifogging, self-cleaning, and oil-water separation. It remains challenging to engineer such surfaces without requiring polar functional groups. This study introduces HFIL, a novel ionic liquid (IL) coating that achieves simultaneous hydrophilic and oleophobic properties via a one-step dip-coating process without relying on polar functional groups.

This study examines the behavior of the Casson nanofluid bioconvection flow around a spinning disc under various influences, including gyrotactic microorganisms, multiple slips, and thermal radiation. Notably, it accounts for the reversible nature of the flow and incorporates the esterification process. The aim of this study is to investigate the influence of reversible chemical reactions on the flow behavior of a Casson nanofluid in the presence of bioconvective microorganisms over a spinning disc.
