Summary: Over 6.2 million people worldwide suffer from moderate to severe vision loss due to corneal disease. While transplantation with allogenic donor tissue is sight-restoring for many patients with corneal blindness, this treatment modality is limited by long waiting lists and high rejection rates. Host-guest interactions have emerged as an important crosslinking strategy for cytocompatible, minimally invasive, injectable tissue substitutes.

Summary: In this study, versatile and on-demand photocontrollable ionic conductive nanocomposite hydrogels were successfully synthesized via host-guest chemistry. The hydrogels showed higher conductivity under visible light irradiation and lower conductivity under UV irradiation, which could be further manipulated by adjusting the surface-area-to-volume ratio of the nanopores and the alkyl chain length of the anions.

Summary: Nitrogen functional groups provide excellent selectivity and efficiency for collector molecules. In this study, collectors with more nitrogen atoms showed better selectivity for the flotation separation of galena from a mixed mineral system. The interaction between the collector molecule and the lead ion was enhanced by the presence of suitable hydrophobic groups, contributing to efficient separation.

Summary: Xanthan gum-based hydrogels were synthesized as efficient adsorbents for dye pollutants removal from wastewaters. The adsorption mechanism was primarily attributed to electrostatic interactions and hydrogel swelling. The hydrogel exhibited a high theoretical q(max) towards Gentian Violet at pH 8 to 9 and could be regenerated with HCl for at least 4 cycles with over 99% dye removal efficiency.

Summary: This study develops and investigates a functional nanocomposite hydrogel using cellulose nanocrystals as a biobased filler, and designs the hydrogel by introducing supramolecular bonding between beta-cyclodextrin and adamantane groups at the interface between cellulose nanocrystals and the polymer matrix. The modified cellulose nanocrystals exhibit good dispersibility in aqueous media, even after modification with the hydrophobic adamantane group, due to electrostatic repulsion among negative charges on the nanocrystal surface. The modification also improves the interfacial compatibility between the filler and the matrix, enhancing the toughness of the hydrogel.

Summary: This study investigates the potential of CO2-triggered and thermo-responsive gel as a plugging agent for heterogeneous sandstone formations, examining its spectral characteristics, rheological properties, adsorption characteristics, and oil recovery efficiency. Results show that the partition of hydrolyzed monomers during polymerization is controlled by CO2 bubbling during gel preparation, while gelation time and rheological properties depend on formation temperature and the presence of salts, with calcium and sulfate salts having the most significant effect. Oil recovery is influenced by permeability distribution and polymer adsorption mitigation, with CO2-triggered gels proving effective in formations with contrasted permeability but less so in homogeneous formations.
