Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

Advanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

In Situ Regenerative Adduct Assisted p‐Type Doping of Organic Semiconductor

Advanced Materials, EarlyView.
An in situ regenerative adduct‐assisted (IRAA) doping strategy is introduced for p‐type doping of organic semiconductors. A regenerating adduct serves as the dopant, enabling highly efficient doping with a choice of counterions. The generality of this approach provides a scalable route to dope a wide range of hole‐transport materials with high thermal ...
