Summary: Organic metal chalcogenides (OMCs) are coordination polymers (CPs) with continuous metal-chalcogen (M-X) networks formed by metal nodes and chalcogen atoms from organic ligands. OMCs exhibit superior electrical transport behaviors and highly tunable chemical and electronic structures, making them promising candidates for thermoelectric materials research.

Summary: Regular rhombic crystals have been synthesized via interface reaction using an 8-hydroxyquinoline derivative coordinated with Zn2+ ions. The crystal size can be controlled by the concentration of the ligand solution. The rhombic crystal exhibits a red-shifted absorption band and orange emission compared to the benzonitrile substituted 8-hydroxyquinoline ligand. Many stacked lamellas were observed in the synthesized crystal, formed by strong interaction forces induced by nitrile groups on the lamella surface.

Summary: The directed self-assembly of liquid crystal polymers has superior optical properties compared to conventional isotropic optical materials. However, the exploration of reflective liquid crystalline polymeric films has been limited due to production challenges. In this study, we investigate stacked polymer cholesteric liquid crystal thin films as a means to generate reflective diffractive optics for circularly polarized light. We present three different exemplar cases to demonstrate the potential of these unique thin polymer films.

Summary: The design and synthesis of new photoactive materials with nano-organization for smart practical applications remains an important task. The study found that chirality and spacer length of polymers have significant effects on their mesomorphic behavior and photo-optical properties, leading to different liquid crystalline phases. Additionally, the presence of lateral methyl substituents in the photochrome/mesogen fragment decreases isotropization temperature.

Summary: This study demonstrates an ideal α-σ relationship in two degenerately doped semi-crystalline polymers using a sequential doping method, allowing the power factors to reach theoretical maxima and exhibiting metallic behavior in heavily doped films. The results show that the power factor maxima appear when the doping state switches from non-degenerate to degenerate, indicating the importance of an optimal α-σ relationship in enhancing TE performance and understanding charge transport in doped polymers.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.

The use of lime instead of metakaolin increases the fluidity and mechanical properties of geopolymers, while the addition of gypsum decreases them. Furthermore, higher lime content exacerbates the negative effect of gypsum.

Summary: This study focuses on the corrosion characteristics of AA 7075 and AA 7075 based hybrid composite fabricated using stir casting and hot rolling techniques. The results show that the hybrid composite produced by hot cross rolling exhibits better corrosion resistance compared to the base metal. The addition of a small amount of graphite improves the bonding between the matrix and reinforcements, and the hot cross rolling enhances this bonding, leading to the formation of a strong passivation oxide layer and increased charge transfer resistance, thereby improving corrosion resistance.
