Summary: The shortage of fresh water worldwide has caused a severe crisis in human health and economic development. Solar-driven interfacial photothermal conversion water evaporation is seen as an environmentally friendly and low-cost method for obtaining clean water. However, the capacity for solar energy absorption limits water transport, particularly in terms of evaporation rates and working life. Therefore, it is crucial to find photothermal conversion materials that can efficiently absorb solar energy and design solar-driven interfacial photothermal conversion water evaporation devices accordingly.

Summary: An in situ self-assembly strategy has been developed to enhance the photothermal therapy of glioblastomas. The strategy utilizes a glutathione-reactive self-assembling polypeptide as a skeleton, with indocyanine green (ICG) as a theranostic agent and cyclic Arg-Gly-Asp [c(RGD)fk] peptides as the targeting group. This strategy provides clearer tumor imaging, prolongs the tumor retention time of the therapeutic agent, and significantly suppresses glioblastoma growth.

Summary: To decrease the dipole polarization rate and reduce the dielectric constant of PAEK resin, a weakly polarizing cyclohexane-based monomer, 1,4-di(4-fluorobenzoyl)cyclohexane (DFBCH), was designed and synthesized as the primary reactant. The incorporation of the bulky fluorene group increased the free volume of the resin, further reducing the dielectric constant. Hydroquinone was utilized to enhance the molecular chain's regularity and reduce dipole relaxation, leading to a lower dielectric constant and dielectric loss of the resin. The PFQEKS series resins showed excellent thermal stability and reduced dielectric constant and dielectric loss with increased hydroquinone content.
