Summary: In this study, carbon nanotubes were grafted by silica nanoparticles to prepare CNTs-SiO2 hybrids, which were then incorporated into an epoxy matrix to construct a superhydrophobic coating. The optimal ratio of CNTs to SiO2 was found to be 1:3, achieving the best hydrophobicity with a water contact angle of 159.3 degrees. The entwined CNTs-SiO2 hybrids not only enhanced water repellency and mechanical durability, but also showed excellent chemical stability under harsh conditions, significantly delaying water freezing time and efficiently melting ice under laser irradiation.

Summary: In order to solve the problem of freezing of wind turbines in cold regions during winter, researchers synthesized a biochar/polypyrrole coating. The coating had a porous structure, irregular dents, and bumps, forming a typical super-hydrophobic nanostructure with sufficient surface area. It exhibited excellent hydrophobic properties with a contact angle of 151 degrees. Wind tunnel tests showed that the biochar/polypyrrole coating effectively reduced the icing area and had the most significant anti-icing effect. This study provides a practical reference for the research of anti-icing coatings on wind turbine blades.

Summary: Nanomedicines for cancer treatment have been extensively studied, but only a few have been approved by the FDA. The mismatch between effort and return raises questions about the field's understanding. The concept of tumor-targeted drug delivery has been based on assumptions that increased drug delivery to tumors improves efficacy and decreased delivery to healthy organs reduces side effects. However, clinical evidence shows that the maximum drug delivery limit to solid tumors has already been reached in humans, yet the efficacy and safety remain unchanged. The approvals of nanomedicine formulations were mostly based on changes in dose-limiting toxicity rather than improved tumor delivery.

Summary: A series of glucose-based degradable superabsorbent hydrogels have been designed and fabricated to address issues related to sustainability, flooding, and drought. These hydrogels were constructed by integrating glucose into cyclic oligomers and block polymers, which were further combined into mechanically-interlocked slide-ring crosslinked materials. The optimized hydrogels exhibited water uptake capacities >30 times their own mass and were derived from renewable natural products, showing potential for high-performance applications.

Summary: Stereocomplexation, the specific interactions among macromolecules, is a powerful design tool in biomaterials. By blending l- and d-KYFIL pentapeptides, we achieved mechanical and morphological transformations from hydrogels to networks of plates. The blends protect l-KYFIL from degradation and maintain stability, while promoting distinct 2D plate morphologies. The X-ray diffraction patterns confirm the changes in molecular packing.

Summary: The maximum capacitive energy stored in polymeric dielectric capacitors is determined by the dielectric breakdown strength of the dielectric polymer. The mechanisms of dielectric breakdown are not clear, but it was found that cyclic polymers exhibit enhanced stability in comparison to linear polymers, resulting in increased dielectric breakdown strength and capacitive energy density. Furthermore, cyclic polymers have a denser packing density than linear polymers.

Summary: Non-aqueous organic redox flow batteries (NAORFBs) are emerging large-scale energy storage systems with a larger voltage window and metal-free nature. However, low solubility, sustainability, and crossover of redox materials are major challenges. In this study, redox active alpha-helical polypeptides suitable for NAORFBs are used, which demonstrate less crossover than small molecule analogs and exhibit low capacity fade and high coulombic efficiency. The polypeptides offer naturally-derived, deconstructable platforms for metal-free energy storage.

Summary: Rigorous investigations of organobase-catalyzed ring-opening polymerizations (ROPs) of cyclic carbonate monomers derived from glucose revealed the scrambling of polycarbonate backbones due to competing transcarbonylation reactions. Experimental and computational studies provided insights into the regiochemistry resulting from the ring-opening and transcarbonylation reactions, which can guide the design and development of advanced carbohydrate-derived polymer materials.
