The functional manganese phthalocyanine nanocrystals have different structures through noncovalent self-assembly confined within micro-emulsion droplets, using manganese phthalocyanine (MnPc) possessing a metal-N-C active center as building block. These nano-assemblies exhibit shape dependent peroxidase (POD)-like catalytic activities, because the emulsifier and MnPc co-mixed assembly reduced the close packing between MnPc molecules and exposed more active sites. The assemblies show higher catalytic activity only emerged under the acidic tumor-like microenvironment, which causes less damage to normal tissues in biomedical applications.

Doping CH3NH3PbBr3 with Bi increases charge carrier density and conductivity, improves photostability, and reduces toxicity; however, it creates deep and localized hole traps, called DY centers, significantly shortening carrier lifetimes. Passivating DY centers with chlorines heals the trap and makes the lifetimes longer than even in pristine CH3NH3PbBr3.

We report a Mn-doped CoNx on N-doped porous carbon (Mn-CoNx/N-PC) electrocatalyst, which shows a small potential difference (ΔE = 0.71 V). Excellent bifunctional catalytic activity is attributed to the influence of Mn and N co-doped on the catalyst
