Summary: By adding a small amount of sodium citrate to an aqueous medium, a highly efficient grafting of bio-derived polyvinyl acetate (PVAc) onto the surface of cellulose nanocrystals (CNCs) was achieved through classical free radical polymerization initiated by cerium ammonium nitrate (CAN). With the increase of SC concentration from 0 to 0.45 mmol L-1, the grafting yields of PVAc on the CNC surface increased from 29.2% to 241.9%. The resulting CNC-PVAc can be fully degraded by soil burial for about 180 days and can be used as a new biodegradable nanofiller or polymer nanocomposite. Moreover, this strategy is applicable to various monomers and different surface groups of CNCs.

Summary: A supramolecular hydrogel system was prepared by forming dynamic covalent crosslinks between 4-carboxyphenylboronic acid (CPBA) and polyvinyl alcohol (PVA). The hydrogel system was further crosslinked with either calcium ions or branched polyethylenimine (PEI) to generate hydrogels with different properties.

Summary: Recent studies have shown that electrochemical grafting of diazonium salts is an efficient method for forming heterogeneous catalysts. This review aims to evaluate the industrial applicability of diazonium-based catalysts, focusing on their mechanical, chemical, and thermal stability. Various approaches to catalyst production using diazonium salt chemistry have been compared, and the most common deactivation routes of catalysts have been discussed. However, more research is needed to experimentally verify the stability and long-term catalytic performance of diazonium-based catalysts.

Summary: Polysorbate 80 (PS80) was reacted with 3-mercaptopropyl trimethoxysilane (SiSH) via a photoinitiated thiol-ene reaction to obtain thiol-functional nanoparticles. These nanoparticles have a high number of thiol residues per particle, allowing for easy modification of particle properties. When added to 3D printing resin, the thiol-functional nanoparticles significantly enhance the curing rate.

Summary: Silicon semiconductor functionalized with graphene layer and catalyst immobilization improves the performance and stability of the photocathode. Altering the stacking configuration of the immobilized catalyst further enhances the electron transfer rate and the photoelectrochemical (PEC) performance. The graphene-coated Si cathode immobilized with catalyst demonstrates remarkable PEC CO2RR performance in neutral solution.

Summary: The bioengineered approach of grafting MSI-78A onto chitosan microspheres enhances its bactericidal performance against Helicobacter pylori. The conjugation does not compromise the antimicrobial activity of MSI-78A and even boosts its effectiveness against H. pylori, making it a potential alternative for antibiotic therapy.

Summary: Functionalized graphene can significantly enhance the interfacial strength and dispersion of graphene materials with thermoset resins. A one-pot direct grafting approach for fabricating epoxy-reactive graphene was developed, which allows for easy control of the grafting density. The graphene composites showed improved fracture toughness, flame retardance, and dispersion, indicating the potential of this approach in enhancing the properties of polymer nanocomposites.

Summary: Molecular bottlebrush (MBB) is an important type of unimolecular nanomaterial, and the chemical and physical properties of MBBs can be significantly affected by the topological structure of backbones and side chains. In recent years, researchers have successfully synthesized polymers with diverse architectures using MBB as building blocks. This mini-review briefly summarizes the recent progress on the tailor of well-defined MBBs with diverse architectures using a grafting-onto strategy combined with controlled polymerization technique.

Summary: Li-rich Mn-based cathodes have been considered promising for lithium-ion batteries due to their low cost and high energy density. However, their capacity degradation and operating voltage decline are major drawbacks. A solution proposed in this study is surface modification with benzene diazonium salts, which creates a stable interface between cathode materials and the electrolyte. The modified cathodes show excellent cycling performance, with a retention rate of 84.2% after 350 cycles at 1C current density, attributed to improved structural and interface stability.

Summary: Solute-solvent interactions are crucial in various fields and have been recognized as an important factor in driving intermolecular association in aqueous media. However, the understanding of solute-solvent effects in complex self-assembly energy landscapes and pathway complexity is limited. This study unravels the role of solute-solvent interactions in controlling chain conformation effects and pathway selection in aqueous supramolecular polymerization. The results reveal previously underappreciated solvent-dependent chain conformation effects and their role in governing pathway complexity in aqueous media.

Summary: We have developed an electrochemical biosensor for lactate determination by immobilizing lactate oxidase onto chevron-like graphene nanoribbons and using them as modifiers of glassy carbon electrodes. The biosensor showed a wide linear concentration range and low detection limit, and demonstrated good agreement with a well-established enzymatic spectrophotometric assay kit.

Summary: In this study, high-quality graphene sheets were prepared and integrated with carbon nanotubes to form free-standing flexible bucky paper. Covalent bonding between the graphene and CNTs was achieved through diazonium chemistry, resulting in improved electrical conductivity and Young's modulus. This work highlights the value of molecular engineering in the design of novel composites for flexible electronics and energy storage, and provides insights into the principles of covalent functionalization of graphene/CNTs.

Summary: A single nanoparticle coating method is reported to form 1 nm polymeric shells with various chemical functional groups and surface charges. Nanosecond thermal energy pulses triggered polymerization in the region only a few nanometers from the surface of magnetic nanoparticles under exposure to alternating magnetic field. Modular coatings with different functional groups and surface charges can be achieved by selecting appropriate monomers.
