This work demonstrates a facile polyethyleneimine-assisted polyol approach for the production of high-quality Rh nanodendrites with very thin triangular branches as subunits. For the first time, the methanol oxidation reaction (MOR) on Rh nanocrystals having a well-defined morphology is investigated in an alkaline medium. The as-prepared Rh nanodendrites exhibit excellent electrocatalytic activity and durability during the MOR in the alkaline medium, indicating that Rh nanocrystals with a specific morphology might be highly promising alternatives to Pt electrocatalysts.

Li2CO3 is an essential component of the solid electrolyte interphase layer in Li batteries. Its formation leads to low initial coulombic efficiency and low energy density, as the cathode is the sole lithium source in a Li-ion battery. Further, Li2CO3 is an insulating by-product that is difficult to decompose on the cathode of Li每air batteries. Its presence results in a large polarization and low energy conversion efficiency. To address these issues, we show that the addition of nanoscaled spinel LiCoO2 as a catalyst can effectively lower the oxidization potential of Li2CO3 to 4.25 V.

We demonstrated an optimized approach for logic-in-memory computing and proved its reliability by experimentally showing, for the first time, a multi-cycle multi-gate material implication logic operation and half-adder circuit within a three-dimensional stack of monolithically integrated memristors. Direct data manipulation in three dimensions enables extremely compact and high-throughput logic-in-memory computing and, remarkably, presents a viable solution for the Feynman Grand Challenge of implementing an 8-bit adder at the nanoscale.

An easy way to improve the anti-oxidation stability of Cu nanowire (NW) films is presented. Flexible and stretchable Cu NW film heaters with a wide operating temperature range (up to 150⊥) and high heating rate (14⊥/s) were investigated.
