Summary: Wild silkworm silk fibers with desirable properties have gained attention, but damaged wild silkworm cocoons are often removed for industrial use. This study introduced regenerated silk fibers made from a solution derived from waste wild silkworm silk cocoons. These regenerated fibers exhibited thick and uniform diameters, making them suitable for medical applications. Furthermore, they possessed similar mechanical strength as native silk fibers and their properties could be adjusted through the drawing process. This research contributes to the production of mechanically stable and tough silk-based fibers using unused protein resources.

Summary: This study presents a robust silk fibroin (SF) scaffold with a reinforced concrete structure, where silk nanofibers serve as the skeleton. The scaffold is prepared using a CaCl2-formic acid dissolving system combined with freeze-drying method, ensuring minimal silk loss and shorter preparation time. Additionally, the scaffold retains the nanofibers of silk, preserving their mechanical toughness. The prepared scaffolds exhibit good biocompatibility and biodegradability. The findings provide a new strategy for manufacturing SF scaffolds and hold great potential for the development of silk fibroin materials in tissue engineering.

Summary: The function of disulfide bonds during the self-assembly and structural evolution of sulfhydryl single-stranded DNA (SH-ssDNA) was explored using in situ liquid-phase transmission electron microscopy (LP-TEM). Sulfhydryl groups induced self-assembly of SH-ssDNA into circular DNA containing disulfide bonds (SS-cirDNA). Disulfide bond interaction triggered the aggregation of two SS-cirDNA macromolecules along with significant structural changes. This visualization strategy provided nanometer resolution structure information in real time and space, benefiting future biomacromolecules research.

Summary: A process intensified synthetic approach is developed for synthesizing gadolinium and cerium co-doped yttrium aluminum garnet (GdYAG:Ce) phosphors in white light-emitting diodes (wLED). The use of a high-gravity rotating packed bed (RPB) reactor enhances molecular mixing and allows precise control and tuning of the dry gel structure, leading to the production of nanosized GdYAG:Ce precursors. The optimized sintering conditions result in emission spectrum adjustable GdYAG:Ce phosphors with reduced energy consumption.

Summary: This study investigates the main factors affecting the filtration efficiency and dust holding performance of pleated filters using a modified numerical model. The results show that the geometric parameters of the pleated filter play a crucial role in the efficiency of air purifiers based on particle loading and filtration efficiency. Stable structural parameters include a bending angle of the pleated filter material in the range of 0 to 60 degrees and a bending portion ratio less than 0.5, which maintain high filtration efficiency. Lower filling degree and shorter length of the pleated filter unit exhibit similar efficiency stability, suggesting that structural parameter changes have minimal effects on filtration performance. The knowledge obtained from this study provides a solid reference for the design of high-performance air-cleaner elements.

Summary: Using in situ liquid cell transmission electron microscopy (TEM), we observed the crystal growth at flow condition with high resolution in real time, and discovered the formation of solute rich dense liquid phase near the surface at ultra-low precursor concentration, which then transformed into nanocrystals. The merging of dense phase droplets accelerated dendritic crystal growth, and the anisotropic crystal growth was controlled by the shape evolution of the dense phase. Our study deepens the understanding of crystal growth mechanisms, which is crucial for determining reaction dynamics and designing hierarchical nanomaterials.

Summary: This study investigates the dehydration kinetics and phase transformation mechanism of Nb3O7(OH). It reveals that H-Nb2O5 can be prepared through low-temperature dehydration and exhibits lower activation energy compared to T-Nb2O5. However, the defect-rich structure of H-Nb2O5 leads to poor photocatalytic activity.
