Summary: The effects of Al2O3 content on the sintering behaviour, microstructure, and physical properties of Al2O3/vitrified bonds and Al2O3/vitrified bond cubic boron nitride (CBN) composites were investigated. Various amounts of Al2O3 promoted the formation of BaAl2Si2O8 and gamma-LiAlSi2O6, increasing the relative crystallinity of the Al2O3/vitrified composite. The Al2O3/vitrified composite showed excellent mechanical properties and suitable interfacial bonding state with the CBN grains, making it a promising high-performance bonding material for superhard abrasive tools.

Summary: This work investigates the improved dielectric performance of acrylic resin elastomer composites using PANI-Ti3C2Tx nanosheets as conductive fillers. The PANI-Ti3C2Tx/AE composites exhibit higher dielectric constant and lower dielectric loss compared to Ti3C2Tx/AE composites. The enhancement is believed to be attributed to the effect of micro capacitors and Maxwell-Wagner-Sillars effect.

Summary: The study investigated the performance and selectivity of Fe(II)EDTA-NO reduction using activated carbon supported bimetallic Fe@Cu composite (AC-Fe@Cu) for nitric oxide removal. The reduction efficiency reached 95.34% in 30 min, with 86.78% N2 selectivity, outperforming previous reduction systems. AC-Fe@Cu exhibited resilience at various pH, temperature, and O2 concentration ranges, maintaining high efficiency after multiple cycles. The bimetal configuration and atomic ratio mediated the reduction efficiency and selectivity, while the unique structure and optimal atomic ratio of Fe to Cu contributed to efficient and selective Fe(II)EDTA-NO reduction.

Summary: Polymeric carbon nitrides, especially the crystalline allotrope known as poly(triazine imide) (PTI), have been found to have great potential for photocatalytic CO2 reduction. However, the poor visible light absorption of pristine PTI significantly hinders its photocatalytic performance. In this study, crystalline carbon nitride nanosheets composed of PTI and melon phase junctions were synthesized via one-pot polycondensation and modified with CdS nanoparticles to create CCN/CdS hybrids with double-junction structures. The resulting CCN/CdS heterostructures demonstrated broad visible-light harvesting, enhanced CO2 adsorption/activation, and improved separation and transfer of photoinduced charges. Thus, the optimized CCN/CdS hybrid exhibited remarkable activity and high stability for photocatalytic CO2-to-CO conversion.

Summary: A new perfect triangular lattice antiferromagnet K2Ni(SeO3)(2) has been synthesized, in which both in-plane and inter-plane geometric frustration is present. The compound shows antiferromagnetic order at T(N) ≈ 7 K. High-field magnetization and electron spin resonance indicate the presence of easy-plane anisotropy. Density functional theory calculations confirm the excellent two-dimensionality of the compound. Thus, K2Ni(SeO3)(2) is a perfect triangular-lattice antiferromagnet with strong frustration and easy-plane anisotropy.

Summary: High-grade gliomas remain difficult to treat despite standard therapy. Charged particle beams, especially carbon ion beams, have the potential to improve treatment outcomes. This systematic review assessed the safety, efficacy, and dosimetry of carbon-ion or proton radiotherapy for high-grade gliomas. The analysis of eleven eligible articles showed that charged particle radiotherapy was effective with manageable side effects. Carbon ion boost appeared to be superior to proton boost, but dose-escalation using proton boost was associated with severe brain necrosis. Further randomized control trials are needed, along with systemic therapeutic options.

Summary: Aqueous Zn-ion batteries have gained significant attention as a promising energy storage candidate due to their safety, cost-effectiveness, and eco-friendliness. However, the cycling stability of Zn metal anodes is a major challenge due to issues such as dendrite growth and hydrogen evolution. Interface engineering strategies, including controllable synthesis of Zn, surface engineering, electrolyte formulation, and separator design, have been developed to address these challenges. This review provides an update on these strategies and discusses future challenges and perspectives for the development of practical AZIBs.

Summary: In this study, the squeeze flow behavior of an upper convected Maxwell fluid between two rigid disks or spheres was investigated. It was found that the velocity field of the Maxwell squeeze flow between two disks is similar to that of a Newtonian fluid when the Deborah number is low. Based on the Newtonian fluid velocity field, the pressure distribution between two parallel disks was analyzed, and a theoretical model of normal squeeze force was developed. The same method was also used to analyze the interaction between two nearly contacting, arbitrary rigid spheres. Analytical expressions for the pressure distribution and normal squeeze force were obtained, which can be used in the contact model for discrete element simulation of wet particle systems with the Maxwell fluid.

Summary: Large reserves, high capacity, and low cost make disordered carbon materials excellent anode materials for sodium-ion batteries (SIBs). Transforming waste into carbon-based materials is significant for sustainable energy utilization. Waste biomass-foam is used as the precursor for hard carbon materials, improving sodium storage performance through a pre-oxidation strategy. The introduction of oxygen-containing groups promotes structural cross-linking and inhibits melting and rearrangement of carbon structure, resulting in a suitable degree of graphitization. The micropore structure is also regulated during high-temperature carbonization, facilitating sodium ion storage in the low-voltage plateau region. The optimized sample exhibits excellent reversible specific capacity and initial Coulombic efficiency, and a full cell with waste foam-derived hard carbon anode shows high efficiency and energy density.
