Summary: This study focuses on achieving direct recycling and reuse of DWSSP, discovering that simply increasing the melting temperature and time cannot completely remove volatile impurities, and the migration process in the melt must be taken into consideration. The study also analyzes the impact of inter-granular grain growth on impurity migration and uses thermal control directional solidification technique to enhance impurity migration and achieve more effective purification of DWSSP.

Summary: In this study, the oxidation states of solution-processed MoO3-x were tuned by doping Nb5+ to improve its hole-selective contact performance with silicon. The contact resistivity between the MoO3-x film and p-type silicon decreased from 161.1 to 62.9 mΩ·cm^2 and the effective carrier lifetime increased from 165.4 to 391.0 μs with the optimal doping concentration of 5%. Similarly, the doping of Ta5+ or V5+ in MoO3-x improved the passivated contact performance with silicon, with the former increasing the concentration of oxygen vacancies and the latter reducing it. The solar cell with the structure of Ag/MoO3-x:Nb/p-Si achieved a conversion efficiency of 18.37%, which is the highest reported for solution-processed MoO3-x/silicon heterojunctions. This work demonstrates a feasible strategy of doping to tune hole selectivity in MoO3-x for high-efficiency solar cells and other optoelectronic device applications.

Summary: This study investigates the synthesis and characterization of molybdenum oxide nanostructures using laser ablation of solids in liquids method. Both nanoparticles and nanosheets composed of molybdenum oxide were formed. The colloid suspension optical absorbance changes with time, resulting in a blue shift within a few days of aging. Raman characterization showed that the material turns into a hydrated molybdenum oxide. Transmission electron microscopy revealed a core-shell structure for the nanoparticles and the nanosheets were found to be composed of orthorhombic alpha-MoO3. The absorption band at 830 nm that develops in the early aging stage of the colloid shows potential for photothermal therapy.

Summary: This study demonstrates the self-assembly of oligomeric clusters (MoO3)(1-6) on the surface of anatase TiO2(101), revealing their dynamic behavior and the role of TiO2 as a template for hierarchically structured oxide growth. The transient mobility of the oligomers is identified as crucial for the formation of a complete overlay, while simulations show a dynamic coupling of reaction steps to TiO2 lattice fluctuations. Further characterizations confirm the thermal stability and chemical identity of the (MoO3)(1) constituents within the material, with a single empty gap state within the TiO2 band structure.

Summary: The study reveals significant chemical interaction at the MoO3/MAPbI(3-x)Cl(x) interface, leading to decomposition of the perovskite and accumulation of PbI2 on the MoO3 cover layer. New compounds such as PbMoO4, PbN2O2, and PbO are formed as a result of the decomposition, suggesting that the direct MoO3/MAPbI(3-x)Cl(x) interface may be inherently unstable. These findings help explain the low power conversion efficiencies of metal halide perovskite solar cells using MoO3 as a hole-transport material with direct contact to perovskite.

Summary: A controllable and continuously oriented three-dimensional AlN skeleton was transformed from a low-cost 3D Al-containing skeleton by ice-templating and nitriding reaction sintering. AlN/epoxy composites with high thermal conductivity were obtained, and the composite containing 39.69 vol% AlN had the highest thermal conductivity of 4.29 W m(-1)·K-1, which was 21.45 times higher than that of pure epoxy. This novel approach has the advantages of low-cost, short processing time, simple operation, and repeatability, providing a new idea for developing heat-conducting polymer composites.

Summary: Fine-grained WNi3Al-B alloys with excellent mechanical properties were successfully fabricated at a low temperature of 1150 degrees C by adding trace boron powder (B) and using spark plasma sintering (SPS). The addition of B promoted the sintering of the alloys through the formation of a low melting point B2O3 phase and the thermite reaction released extra heat. However, excessive B content led to the formation of more hard brittle phases and the evaporation of B2O3, resulting in weakened strength and pore formation in the sintered alloys. Among all B-containing WNi3Al alloys, the 0.1B alloy exhibited the optimal mechanical properties due to its small tungsten grain size, heterostructural binder phase, minimal formation of hard brittle phases, obstruction of dislocation movements by the Al2O3 phase, and tungsten transgranular cleavage fracture mode.

Summary: Solar water evaporation technology utilizes sunlight as an energy source to achieve low-cost desalination. However, many studies have focused on specific system performance while neglecting the universality and compatibility of evaporator designs. This study used molecular dynamic simulations to predict the performance of photo-thermal conversion (PTC) materials and fabricated hierarchical evaporators with promising evaporation performance. The evaporators constructed with dual-layered hydrogel/aerogel structures and vertically aligned channels have achieved a high evaporation rate of 1.61 kg m-2 h-1 under 1.0 sun illumination.

Summary: Composite modulation in the superparaelectric state of the BTBZ-CT system is proposed as an effective strategy to achieve both NTCC and excellent energy storage performance in dielectric ceramics. The addition of BZ and CT to BT ferroelectrics can move the SPE state to the normal use temperature zone, resulting in enhanced NTCC characteristics and energy storage performance. Furthermore, intentional precipitation of CT at grain boundaries can refine the grain size, increase the bandgap, and strengthen the local electric field distribution, thereby enhancing the breakdown electric field.

Higher purity calcia results in well-developed grains and improved hydration resistance, leading to better high-temperature strength and thermal shock resistance. In contrast, lower purity calcia crucibles exhibit inferior properties. Therefore, high-purity calcia is considered a potential refractory for manufacturing oxide crucibles.

Summary: To raise the operating temperature of Si-based ceramic matrix composites (CMCs), researchers have applied thermal/environmental barrier coating (T/EBCs) materials, typically rare earth silicates. However, the high thermal conductivity and the mismatch of thermal expansion have been major challenges in developing new materials that can offer thermal insulation and environmental protection to CMCs. In this study, entropy engineering was used to create a multicomponent equi-atomic single-phase pyro silicate with extremely low thermal conductivity and enhanced water vapor corrosion resistance. The research findings show the potential of high entropy disilicates in achieving ultra-low thermal conductivity and low weight loss in corrosive environments.

Summary: This study provides an atomic-scale description of the high-velocity impact of alpha-Al2O3 particles onto an alpha-Al2O3 substrate during Aerosol Deposition (AD). The results suggest that the crystal orientation plays a crucial role in both plasticity and damage of the nanoparticles. Impact velocity has a direct correlation with plasticity and fragmentation, but adhesion efficiency has only a marginal increase. The crucial element lies in the substrate's surface alterations caused by the fragments left on the substrate after impact.

Summary: This study characterized the long-term and repeated ablation properties of modified Cf/HfC-SiC composites with YB4-Al2O3-Si3N4 under an air plasma torch. The structural stability and viscosity of the oxide layer were found to affect the ablation resistance of the composites. By forming nano c-HfO2 grains and high-viscosity Al-Si-Y-O glassy phase, the structural stability of the oxide layer was improved, resulting in enhanced ablation resistance. However, the oxidation of Si3N4 led to the formation of NO, NO2, and excessive SiO2 glassy phase, which resulted in a porous structure and reduced the viscosity of the oxide layer. Therefore, the addition of Si3N4 decreased the ablation resistance of the composites.

The presence of a tetragonal-pseudocubic phase boundary and a spontaneous ferroelectric-relaxor transition at specific compositions were confirmed. The introduction of a tetragonal-pseudocubic phase boundary improved the piezoelectric properties and suppressed the spontaneous ferroelectric-relaxor transition.
