Summary: Colloidal Ag particles decorated with Fe3O4 islands can be activated as inverse catalysts for C(sp(2))-H heteroarylation either electrochemically or photochemically. The silver-iron oxide (SIO) particles are reduced into redox-active forms by cathodic charging at mild potentials or short-term light exposure, and can be reused multiple times by magnetic cycling without further activation. The reduction peak shift is attributed to the overpotential produced by surface Fe3O4, which separates residual Ag ions or clusters from bulk silver. The catalytic efficiency of SIO is maintained even with acid degradation, and can be counteracted by simple addition of water to the reaction medium.

Summary: A new tandem reaction involving photoinduced double hydrogen-atom transfer and deoxygenative transborylation has been developed for the chemo- and site-selective reduction of nitroarenes. The reaction proceeds under catalyst-free, room temperature conditions, and shows excellent yields. The use of isopropanol as a hydrogen donor and tetrahydroxydiboron as a deoxygenative reagent makes this method convenient and cost-effective. The reaction can tolerate a wide range of reducible functional groups and selectively reduces the nitro group at the electron-deficient site.

Summary: A magnetic recyclable ZnFe2O4/BiOBr (ZFB) heterojunction microspheres with oxygen vacancies were prepared, which showed improved separation efficiency and utilisation of photogenerated carriers. The ZnFe2O4 induced the growth of nanolayer structure on the surface of BiOBr, leading to increased diffraction peak intensity ratio and specific surface area. The ZFB exhibited a smaller bandgap, wider visible response range, and higher photogenerated carrier migration and separation efficiency compared to BiOBr. It could effectively degrade organic molecules such as Rhodamine B, norfloxacin, and sulfadiazine, with degradation efficiencies above 86.64%. The ZFB photocatalytic material demonstrated high recyclable efficiency and potential for simultaneous degradation of various micropollutants in organic wastewater.

Summary: This work successfully functionalizes L-proline on the surface of superparamagnetic iron oxide nanoparticles (SPION) via a simple hydrothermal method, and further attaches Cu2+/Cu-0 nanoparticles onto the surface of SPION@L-proline by an in-situ deposition method. The developed nano-photocatalyst is characterized in detail, confirming its structure and performance. The Cu-0-based magnetic nano-photocatalyst shows slightly enhanced catalytic activity and demonstrates efficient photocatalytic degradation of dyes under solar irradiation. The superparamagnetic properties enable easy separation and recyclability of the nano-photocatalyst. The Cu2+/Cu-0-based magnetic nano-photocatalyst has potential applications in wastewater treatment due to its high photocatalytic efficiency, cost-effectiveness, magnetic separation performance, non-toxicity, and thermal and chemical stabilities.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
