Polysarcosine emerges as a promising alternative to polyethylene glycol (PEG) in biomedical applications, boasting advantages in biocompatibility and degradability. While the self-assembly behavior of block copolymers containing polysarcosine-containing polymers has been reported, their potential for shape transformation remains largely untapped, limiting their versatility across various applications. In this study, we present a comprehensive methodology for synthesizing, self-assembling, and transforming polysarcosine-poly(benzyl glutamate) block copolymers, resulting in the formation of bowl-shaped vesicles, disks, and stomatocytes.

Development of efficient drug delivery systems remains a critical challenge in pharmaceutical applications, necessitating novel approaches to improve drug loading and release profiles. In this study, a novel method is presented for fabricating crosslinked polydopamine particles (XPDPs) using a water/water Pickering emulsion system. The emulsion is composed of poly(ethylene glycol) and dextran, stabilized by polydopamine (PDA) particles.

Given extremely high porosity, aerogels have demonstrated remarkable advantages in serving as thermal insulation and wave-transparent materials. Unfortunately, their practical applications are greatly confined by their inherent fragility. The recent emergence of polymer aerogels presents an ideal platform for the development of flexible aerogel films.

Flexible nanocomposites incorporating nanofibrillated cellulose (NFC) hold significant promise for thermal management applications. However, their heat dissipation performance is primarily constrained by the interfacial thermal resistance (). In this work, 1-pyrenemethylamine hydrochloride (PyNH) noncovalent functionalized graphene subsequently self-assembled with NFC through a vacuum-assisted filtration technique.

The conductive paths (CPs) established by defects in halide perovskites (HPs) tend to be disrupted under external influences, leading to deterioration of their RRAM performances. Here we propose an effective strategy to enhance the CPs in HP RRAMs by doping Ag to partially substitute Pb in MAPbI, which facilitates the nonlocalized growth of Ag CPs and thereby improves the stability of CPs. The optimal doped device demonstrates excellent RRAM performances including high ON/OFF ratios (>10), long retention (>10 s), large endurance (>10 cycles), uniform parameters, and excellent yield.
