Summary: Researchers have observed an insulator-to-superconductor transition driven by valence fluctuation in the van der Waals insulator GeP. The transition is caused by valence skipping of the Ge cation, transforming GeP from a layered compound to a three-dimensional covalent system and resulting in a maximum superconducting critical temperature of 10 K.

Summary: In this study, a model of two coupled complex scalar fields under finite temperature and an external magnetic field is investigated using the nonperturbative method of optimized perturbation theory. The results are contrasted with those obtained using perturbation theory and the one-loop approximation, revealing phenomena related to inverse symmetry breaking and symmetry nonrestoration.

Summary: Based on pseudo-ternary phase diagram and microscopic observation, three eutectic high entropy alloys (EHEAs) with uniform lamellar microstructure were designed. One of the alloys exhibits better tensile property at room temperature. The formation of AlCoCrNi EHEAs was found to be related to the ratio of (Co, Ni) to Al.

Summary: Experimental studies show that random assemblies of particles subjected to cyclic shear undergo a reversible-irreversible transition, where the relaxation time tau diverges with increasing vortex density B and shear amplitude d. Both B-driven and d-driven transitions fall into the same universality class, exhibiting critical behavior.

Summary: We present a systematic study of the electronic and magnetic properties of two-dimensional ordered alloys, and find that both direct exchange and superexchange models can explain the magnetic couplings in the hosts and doped systems. Magnetic impurities do not affect the magnetic ordering in the pure phases, and frustration in antiferromagnetic coupling may lead to lower magnetic ordering temperature in doped systems.

Summary: In this study, an anisotropic single-domain hydrogel with lyotropic liquid crystal property and thermochromism was fabricated by combining hydroxypropyl cellulose (HPC) with a thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) hydrogel through mechanical shearing. The prepared long-range ordered HPC- PNIPAM hydrogels exhibited bright and uniform interference colors between crossed polarizers, and showed stimulus-responsive behavior to temperature and ionic strength. Particularly, the oriented HPC- PNIPAM hydrogel had a wide thermoresponsive range that could be adjusted by the HPC and PNIPAM content, providing a solution to the narrow or fixed temperature sensing range of hydrogels.

Summary: This study investigates the microphase separation and self-assembly of random multiblock copolymers composed of A and B homo-oligomers using computer simulations. The correlations between different types of macromonomers are controlled by the reaction probabilities. The results suggest that an increase in the Flory-Huggins parameter chi leads to microphase separation into lamellar structures or irregularly arranged domains.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.

Summary: Peptide nanotechnology bridges the gap between materials and biological worlds by utilizing self-assembly of short-peptide building blocks. Hydrogels engineered from these short peptides show great potential in biomedical applications, but their weak mechanical properties and limited functional diversity need to be addressed. Nanoengineering the networks of these hydrogels by incorporating small molecules, polymers, and inorganic/carbon nanomaterials can enhance their mechanical properties and expand their functional diversity.
