Summary: In this study, we investigate the electronic and phonon properties of I-II2-III-VI4 systems using first principles simulations. We identify the unique properties associated with the structural and atomic diversity, and predict the electronic and thermal transport in these materials by studying the structure-property relations of electronic and phonon band structures. Moreover, we identify the property trends related to the average atomic number and mass dissimilarities.

Summary: In this study, sulfur-based sphalerite quaternary chalcogenides were synthesized and their temperature-dependent electronic, thermal, and structural properties were investigated. The variation in stoichiometry was found to affect the materials' conductivity, while lattice anharmonicity contributed to their low thermal conductivity. Comparisons with zinc blende binaries were made to understand the origin of this low thermal conductivity in quaternary chalcogenides.

Summary: In this paper, we described the optically controlled braking and acceleration of transition metal dichal-cogenide (TMD) based tubular catalytic micromotors. By electrodeposition of a thin WS2 or MoS2 outer layer, the micromotors gain optical responsive properties and light-induced heating. The acceleration phenomenon is explained by a mixed effect of electron generation and promotion, resulting in increased decomposition kinetics. On-demand braking and acceleration can be achieved in the full electromagnetic spectrum, providing an alternative approach to control catalytic micromotor propulsion for various applications.

Summary: By controlling the composition of Sb2Se3, this study found that it does not allow an extended range of nonstoichiometric conditions but compensates for excess Sb or Se by forming secondary phases. It was also discovered that operating under Se-rich conditions can improve the crystalline orientation, possibly due to the formation of a MoSe2 phase in the back interface.

Summary: The study investigated the impact of different pore structures on 2D-TMD using density functional theory, revealing higher stability for smaller pores, lattice deformation and decreased Young's modulus with increasing pore size. Certain systems exhibited magnetism due to missing metal atoms, while the emergence of metal states at pore edges resulted in some systems being half-metallic. Oxygen passivation restored metallic behavior in the systems.

Summary: This study presents a silicon dielectric metamaterial (SDM) composed of two outer symmetric semi-circular rings and two inner symmetric split-ring resonators (SRRs). The electromagnetic responses of the SDM device in different modes were studied through numerical simulations and experiments. Increasing the structure height of the SDM device resulted in red-shifted resonances and stronger intensities. This study provides a new design strategy for the development of frequency filtering, polarization switching, and resonance modulation characteristics in THz-wave applications.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
