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: The study investigates crystal growth in undercooled melts in the GeSe2-rich region of the (GeSe2)x(Sb2Se3)1-x system. Two crystalline phases (Sb2Se3 and GeSe2) were directly observed using infrared microscopy. The growth rates of GeSe2 crystals depend only on temperature and are independent of the system's composition. The competitive growth of Sb2Se3 and GeSe2 is explained using existing crystal growth theories. New viscosity data for the (GeSe2)0.9(Sb2Se3)0.1 composition were obtained to complement the viscosity behavior in the (GeSe2)x(Sb2Se3)1-x system. The combination of growth and viscosity data provides valuable insights into crystal growth and allows for the prediction of crystal growth rates over a wide temperature range in the (GeSe2)x(Sb2Se3)1-x system.

Summary: In the past two decades, environmental issues caused by human activities for development have become more prominent. Ignoring climate change and the stagnant approach of major oil industries have resulted in the melting of glaciers and the shrinking of mountain peaks. The imbalance in natural resources is leading to various crises that can affect livelihoods. Photocatalysis, particularly using transition metal chalcogenides (TMCs), is considered a simple and sustainable technique to generate energy and degrade pollutants. Among TMCs, molybdenum chalcogenides nanostructures show exceptional properties and promise in efficient hydrogen production and dye degradation through photocatalytic water splitting. This review discusses the applications of Mo-based chalcogenides nanostructures in hydrogen production and dye degradation, as well as the progress made in enhancing their photocatalytic activity.

Summary: This study compared two methods, adsorption and in situ incorporation, for preparing hybrid polyphenol/hydroxyapatite nanoparticles. The results showed that adsorption of polyphenols on pre-formed nanoparticles did not change their properties, while in situ incorporation inhibited hydroxyapatite formation but resulted in higher loadings. Most hybrid particles exhibited a burst effect followed by slow release over time.

Summary: The crystal growth kinetics of Sb2Se3 in (GeSe2)x(Sb2Se3)1-x were studied, revealing two types of crystal growth: lateral crystal growth at the surface and crystal growth in the volume of the bulk sample. The transport of structural units during crystal growth can be described by viscosity in volume crystal growth, while it is influenced by surface diffusion in surface crystal growth.

Summary: The effects of different preparation methods and heat treatments on Fe0.25TaSe2 samples were studied. It was found that the lattice parameters were not affected, but the magnetic critical temperature and hysteresis showed significant changes. The magnetic ordering temperature ranged from 33-60 K, and the coercive field values were high, indicating a strong magnetocrystalline anisotropy. The differences in magnetic characteristics were attributed to the distribution of Fe atoms.

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.
