Summary: Porous Bi2O3-Bi2S3 composite sheets were synthesized through a combination of chemical bath deposition and hydrothermal reaction, and the Na2S precursor concentration was varied to investigate the impact on the structure and vulcanization degree of the composites. The use of suitable sulfide precursor concentration during the hydrothermal reaction enabled the control of the etching rate of the Bi2O3 template and the regrowth rate of Bi2S3 crystallites, resulting in the formation of porous Bi2O3-Bi2S3 sheets. The presence of Bi2S3 crystallites and the porous structure in the composites contributed to improved visible-light absorption and separation efficiency of photogenerated charge carriers, making them highly promising for photoactive device applications.

Summary: This research shows that lattice strain can be used to adjust the defect concentration and optimize the electrical transport performance. Theoretical calculations demonstrate that lattice strain can effectively increase the formation energy of Ge vacancies, reducing carrier scattering and improving carrier mobility. Experimental results confirm that lattice strain obtained through high-energy ball milling combined with spark plasma sintering can reduce the concentration of Ge vacancies, leading to high carrier mobility. Additionally, carefully modulating the nominal content of Ge in Ge0.90Sb0.08Te alloy results in a high ZT of 2.0 at 723 K.

Summary: This study systematically investigates the thermophysical performance of tobacco granules and proposes an effective strategy of raising the thermal conductivity by introducing nanoparticles of high-thermal-conductivity-materials (copper, silver, and graphene). This not only improves the thermal conductivity by 35% but also reduces the maximum temperature for generating aerosol. Furthermore, introducing copper and silver particles in the tobacco granules is favorable for enhancing the antibacterial effect. This method is worth promoting for improving the thermal conductivity of other plant-derived heated products.

Summary: High thermoelectric performance is achieved in GeTe-based thermoelectric materials by single doping trivalent dopant M (M=In, Sb, Bi), resulting in a conversion efficiency of -10.3% and power density of -0.6 W cm-2. Doping with Bi decreases deformation potential and optimizes the power factor, leading to the highest ZT value of -1.9. In-doped GeTe exhibits low lattice thermal conductivity at ambient temperature, while Bi-doped GeTe significantly reduces lattice thermal conductivity at high temperature, resulting in the best performance among the single-doped GeTe-based thermoelectric materials.

Summary: Tin selenide (SnSe) crystals were found to have potential power generation and Peltier cooling performance. By filling Sn vacancies, the scattering of defects was weakened and the carrier mobility was boosted, resulting in a power factor exceeding 100 μW/(cm·K^2) and a figure of merit (ZT) of approximately 1.5 at 300K, with an average ZT of about 2.2 from 300 to 773K. A single-leg efficiency of about 12.2% under a temperature difference (DT) of about 300K and a seven-pair Peltier cooling DTmax of about 61.2K at ambient temperature was achieved.

Summary: This study reveals the origin of anomalously low lattice thermal conductivity in Cd-alloyed Mg3Sb2 Zintl compounds through complementary bonding analysis. Weakened chemical bonds and lattice instability induced by 5p-4d electron states between Sb and Cd trigger giant anharmonicity and increase phonon scattering. Additionally, bond heterogeneity augments Umklapp phonon scatterings. Moreover, weakened bonds and heavy element alloying soften the phonon mode and significantly decrease the group velocity.

Summary: In this study, a TiO2/WO3 heterostructure nanocomposite with oxygen vacancy defects was synthesized through a simple sol-gel method. The introduction of oxygen vacancies reduced the bandgap and expanded the light absorption range, while the TiO2/WO3 heterostructure increased the photogenerated carriers and facilitated their separation. The resulting TiO2/WO3 nanocomposites exhibited enhanced photocatalytic activity and showed excellent stability under sunlight, providing a novel approach for designing and preparing TiO2-based composite photocatalysts.

Summary: Cu1.97Se-x wt.% In2O3 (x = 0-1) bulk composites were fabricated using high-temperature melting and spark plasma sintering technology. Doping In3+ in Cu vacancies can adjust the carrier concentration and modify the band structure of Cu1.97Se. Additionally, excessive In2O3 particles help to construct multiple lattice defects, enhance phonon scattering, suppress the migration of Cu ions, and significantly reduce thermal conductivity. A peak ZT value of 1.43 was obtained for the Cu1.97Se-0.5 wt.% In2O3 bulk specimen at 873 K, which is almost 150% higher than that of the pristine sample. The thermoelectric conversion efficiency and mechanical properties of the composites sample were also measured, suggesting the potential use of Cu1.97Se-based nanocomposites in power generation devices.

Summary: In order to uniformly disperse ceramic reinforcements in the copper matrix composites, this study used Carbon Polymer Dot (CPD) as the carbon source and Cu-1.0%Ti alloy powder as the matrix to prepare in-situ synthesized TiC/Cu composites. The results showed that TiC nano-precipitates formed at the grains interior and grain boundaries with similar particle sizes to CPD, and maintained a uniform distribution. The 0.3 wt% CPD/Cu composite exhibited the best strength-plastic compatibility, achieving an ultimate tensile strength of 385 MPa and an elongation of 21%, attributed to the dislocation hindrance caused by nano-carbide and excellent interface bonding between nano TiC and the Cu matrix. Density function theory calculation supported the experimental results by demonstrating a tighter and stronger interface contact. This work presents a new approach for studying in-situ carbide precipitates.
