As a naturally occurring cytolytic peptide, melittin (Mel) has strong activity and is potent therapeutic peptide for cancer therapy. However, the serious hemolytic of Mel largely impedes its clinical applications. In this work, based on interactions between proteins/peptides polyphenols, we develop tannic acid-Fe3+ metal-phenolic network (MPN)-based strategy that can convert from foe to friend via shielding positive charges reducing activity. Besides, an immune adjuvant resiquimod (R848)...
Abstract Cross‐linked bismaleimide (BMI) resin is a high‐performance thermoset that cannot be remelted and reshaped. Therefore, carbon‐fiber‐reinforced BMI (CF/BMI) composites are difficult to recycle.

Solar photovoltaic (PV)-rich power distribution systems are networked Cyber-Physical Systems (CPS). These control where multiple computing nodes and diverse intelligent agents interact with the physical world in real-time. However, presence of components renders them vulnerable to potential cyber-attacks, cyber-intrusions, other malicious events.
