Summary: Monoclinic Cu-3(MoO4)(2)(OH)(2) nanosheets with predominantly exposed (010) facet were successfully synthesized using orthorhombic phase (NH4)2Mo4O13 nanosheets as the precursor through a hydrothermal method. The formation mechanism of Cu-3(MoO4)(2)(OH)(2) nanosheets from (NH4)2Mo4O13 nanosheets was discussed in detail. The crystal structure and morphology of Cu-3(MoO4)(2)(OH)(2) nanosheets were characterized by various techniques. The photocatalytic performance of Cu-3(MoO4)(2)(OH)(2) nanosheets was evaluated through water splitting under simulated sunlight, showing higher photocurrent density and H-2 generation compared to the control ST01. These results suggest the potential application of Cu-3(MoO4)(2)(OH)(2) nanosheets in photocatalysts and photovoltaic nanodevices.

Summary: This study tests the hypothesis that N-level systems with strong single-ion anisotropy can be described by a classical approximation based on SU(N) coherent states. The finite temperature inelastic neutron scattering data of the spin-one antiferromagnet Ba2FeSi2O7 is modeled using a generalized Landau-Lifshitz dynamics for SU(3) spins. Unlike the traditional classical limit based on SU(2) coherent states, the results obtained with classical SU(3) spins show good agreement with the measured temperature dependent spectrum. The developed SU(3) approach provides a general framework to understand a broad class of materials with weakly coupled antiferromagnetic dimers, trimers, or tetramers, and magnets with strong single-ion anisotropy.

Summary: A robust layered antiferromagnetism with a high Neel temperature is predicted in a MXene Cr2CCl2 monolayer, providing an ideal platform for a magnetoelectric field effect transistor. The band splitting between spin-up and spin-down channels can be induced by an electric field, breaking the inversion symmetry between the lower Cr layer and the upper Cr layer. The magneto-optic Kerr effect can detect this magnetoelectricity in a collinear antiferromagnet with zero magnetization.

Summary: In this work, a strategy of efficient utilization of carbon nanotubes (CNTs) in producing CNT incorporated aramid papers is demonstrated. The layer-by-layer self-assembly technique is used to coat the surfaces of meta-aramid fibers and fibrils with CNT, providing novel raw materials available for large-scale papermaking. The hierarchical construction of CNT networks resolves the dilemma of increasing CNT content and avoiding the agglomeration of CNT, which is a frequent challenge for CNT incorporated polymeric composites. The composite paper exhibits a high permittivity and dielectric loss tangent at a low CNT loading, and achieves high-efficiency microwave absorption in the X-band.

Summary: In this study, the structure, magnetic and ferroelectric properties of the exfoliated monolayer AgCr2S4 have been investigated using density functional theory. The results show that the monolayer AgCr2S4 exhibits two-dimensional ferromagnetism and loses bulk polarity due to the emergence of centrosymmetry upon two-dimensional confinement. Surface adsorption has a nonmonotonic effect on the ionic conductivity while having little impact on the layered magnetic structure.

Summary: One-step conversion of low-purity polyolefins to branched liquid alkanes is achieved using a reusable, noble metal-free and impurity-tolerant bifunctional catalyst, MoSx-Hbeta. The catalyst works under mild conditions and is compatible with various types of polyolefins, including those mixed with heteroatom-linking polymers and contaminated polyolefins. The hydroconversion process demonstrates high yields of small alkanes, even at low temperatures, making it a promising method for chemical recycling of waste plastics.

Summary: With the rapid expansion of two-dimensional (2D) magnetic materials, noncollinear topological magnetic textures in 2D materials, known as magnetic bimerons, are increasingly gaining attention. This study predicts that centrosymmetric transition metal halide CoX2 (X = Cl, Br) monolayers are promising candidates for observing frustration-induced bimerons. The bimerons crystallize into a stable triangular lattice under an appropriate magnetic field and have smaller size and more flexible tunability compared to other magnetic structures. The biaxial strain can also be used to tune the bimeron lattice in these materials.

Summary: This study investigates the possibility of a mechanism beyond post-translational modifications to regulate protein function. It shows that hydrogen sulfide (H2S) can bind to the active-site copper of Cu/Zn-SOD, enhancing electrostatic forces and facilitating electron transfer. The physiological relevance of this H2S effect is demonstrated in in vitro and in vivo models where the cardioprotective effects of H2S depend on Cu/Zn-SOD.
