Stable, recyclable, hybrid ionic-electronic conductive hydrogels with non-covalent networks enhanced by bagasse cellulose nanofibrils for wearable sensors.

Conductive hydrogels are utilized in flexible sensors due to their high-water content, excellent elasticity, and shape controllability. However, the sharp increase in resistance of this material under enormous strain leads to instability in the sensing process. This study presents a straightforward method for creating a stable, recyclable, hybrid ionic-electronic conductive (HIEC) hydrogel via a simple one-pot strategy using polyvinyl alcohol (PVA), bagasse cellulose nanofibrils (CNF), and graphene(G) with sodium dodecylbenzene sulfonate (SDBS).

Temperature-responsive gating chitosan-based microcapsules for controlled release of urea fertilizers.

Polysaccharides-based smart fertilizers are essential for promoting plant growth, yet significant challenges exist in achieving stable structures and synchronizing nutrient release and plant growth. This study developed a temperature-responsive gating chitosan-based microcapsule (CTSMC-g-PNIPAM) by grafting N-isopropyl acrylamide (NIPAM) onto chitosan microcapsules (CTSMC) via atom transfer radical polymerization (ATRP). The interfacial crosslinking of chitosan (CTS) and terephthalendehyde (TPA) formed the CTSMC matrix with a hollow chamber structure and ensured stability.

A green extraction technology of lignocellulose from cassava residue by mechanical activation-assisted ternary deep eutectic solvent.

Lignocellulose (LC) is a natural polymer material that holds immense potential for various applications. However, extracting LC from biomass wastes with high-starch content has been challenging due to low selectivity and yield. In this study, LC was prepared from cassava residue (CR) via a combination of mechanical activation pretreatment and a citric acid (CA)-enhanced ternary deep eutectic solvent (TDES) consisting of choline chloride (ChCl), lactic acid (LA), and CA.

Highly Stable Ni-B/Honeycomb-Structural AlO Catalysts for Dry Reforming of Methane.

WO/BiOBr S-Scheme Heterojunction Photocatalyst for Enhanced Photocatalytic CO Reduction.

The photocatalytic CO reduction strategy driven by visible light is a practical way to solve the energy crisis. However, limited by the fast recombination of photogenerated electrons and holes in photocatalysts, photocatalytic efficiency is still low. Herein, a WO/BiOBr S-scheme heterojunction was formed by combining WO with BiOBr, which facilitated the transfer and separation of photoinduced electrons and holes and enhanced the photocatalytic CO reaction.

To improve the water absorbency and water-retention rate of superabsorbent materials, a porous calcium carbonate composite superabsorbent polymer (PCC/PAA) was prepared by copolymerization of acrylic acid and porous calcium carbonate prepared from ground calcium carbonate.

Ni-Ti Intercalated and Supported Bentonite for Selective Hydrogenation of Cinnamaldehyde.

Ni-Ti intercalated bentonite catalysts (Ni-Ti-bentonite) and Ni-TiO supported bentonite catalysts (Ni-TiO /bentonite) were prepared, and the effects of Ni-Ti supported and intercalated bentonite on the selective hydrogenation of cinnamaldehyde were investigated. Ni-Ti intercalated bentonite enhanced the Brønsted acid sites strength, decreased the acid amount and Lewis's acid sites strength, which inhibited the activation of the C=O bond and contributed to selective hydrogenation of the C=C bond. When Ni-TiO was supported on bentonite, the acid amount and Lewis's acid strength of the catalyst increased, providing additional adsorption sites and increased the acetals byproducts.

Sulfur Vacancy and Ti C T Cocatalyst Synergistically Boosting Interfacial Charge Transfer in 2D/2D Ti C T /ZnIn S Heterostructure for Enhanced Photocatalytic Hydrogen Evolution.

Constructing an efficient photoelectron transfer channel to promote the charge carrier separation is a great challenge for enhancing photocatalytic hydrogen evolution from water. In this work, an ultrathin 2D/2D Ti C T /ZnIn S heterostructure is rationally designed by coupling the ultrathin ZnIn S with few-layered Ti C T via the electrostatic self-assembly strategy. The 2D/2D Ti C T /ZnIn S heterostructure possesses larger contact area and strong electronic interaction to promote the charge carrier transfer at the interface, and the sulfur vacancy on the ZnIn S acting as the electron trap further enhances the separation of the photoinduced electrons and holes.

An overview of photocatalysis facilitated by 2D heterojunctions.

Two-dimensional (2D) photocatalysts have attracted considerable research interest in the past decades due to their unique optical, physical and chemical properties.
