Summary: The ternary compound CuSbSe2-alloyed PbTe, CumPb100SbmTe100Se2m (CLAST), exhibits outstanding n-type thermoelectric transport behavior, with hierarchical Cu-based precipitates and interstitials playing a key role in balancing phonon and carrier transport. By introducing a small amount of CuSbSe2 alloying, the room-temperature carrier concentration and power factor can be optimized, while embedded Cu-based nanostructures help lower the lattice thermal conductivity. Additionally, excess Cu atoms can enhance carrier concentration and mobility, contributing to a high power factor in Cu3.3Pb100Sb3Te100Se6. The Cu-based hierarchical structures in CLAST samples synergistically optimize phonon and carrier transport properties, leading to high ZT values at both low and high temperatures.

Summary: Hierarchical porous structures of Ni-3(CO3)(OH)(4) and (NixCo1-x)(6)(CO3)(2)(OH)(8) .H2O were synthesized via a hydrothermal route, with chloride ions playing a crucial role in the morphology of the (Ni,Co)(6)(CO3)(2)(OH)(8) .H2O structures. The electrochemical properties of the products were found to be influenced by their chemical composition and surface property, with Ni-3(CO3)(OH)(4) exhibiting higher specific capacitance but poorer rate performance and cycle stability compared to (Ni,Co)(6)(CO3)(2)(OH)(8) .H2O.

Summary: The biointerface engineering of living cells by creating an abiotic shell has implications for improving cellular behavior and promoting the development of living cell hybrid materials. Active nanoencapsulation of single cells endows them with motion ability that they do not possess inherently. The emerging motion characteristics of the encapsulated cells can be self-regulated, leading to self-sorting between mother cells and daughter cells in a proliferated Saccharomyces cerevisiae cell community. This study not only serves as a new technique in single-cell biology analysis and sorting, but also opens up opportunities to manipulate cell functionality by creating biohybrid materials.

Summary: A barrier for biological applications of DNA structures is their instability to nucleases. This study explores the use of UV-mediated thymine dimerization to crosslink and stabilize DNA nanostructures. The researchers compare different methods of DNA irradiation and show that all approaches can achieve nuclease protection, but with varying levels of off-target crosslinking and damage. They also demonstrate a mild irradiation condition that enhances serum stability while maintaining DNA function. This methodology has potential applications in nucleic acid therapy and nanotechnology.

Summary: The temperature and strain fields play crucial roles in regulating the fibrous aggregate structure of polyamide 6. Through systematic analysis of oriented polyamide 6 plates, it was found that the stretching process induces the formation of more thermally stable alpha-form crystals, which gradually transform into gamma-form crystals with increasing stretching temperature. Additionally, crystal chips transform into fibrils during the stretching process.

Summary: During the fiber spinning process, the stretching process plays a key role in improving the mechanical properties of materials. This study comparatively investigated the effect of hydrogen bond density on the aggregation structure evolution of three polyamides. The results showed that with the increase of hydrogen bond density, the tensile strength and crystallinity of the materials gradually increased. Furthermore, significant differences were observed in the phase transition process of the three polyamides due to the difference in hydrogen bond density.
