During water electrolysis, multifunctional electrocatalysts with outstanding functionality and endurancemust be thoughtfully constructed and designed. Below, we report a hollow NiS@Ni2P nanoframeheterostructure that works well as a substitute catalyst for the urea oxidation and general water splittingreactions. The hollow NiS@Ni2P nanoframe was synthesized by ion exchange, sulfurization and phosphating,which is favorable for achieving a heterostructure. The NiS@Ni2P catalyst exhibits excellent catalyticactivity and strong long-term stability in 1.0 M KOH solutions for the hydrogen evolution reaction, whichneeds 121 mV to achieve 10 mA cm2. And for the oxygen evolution reaction, the catalyst needs 311 mVto acquire 50 mA cm2. These advantages come from the optimal electronic structural configuration,hierarchical hollow nanoframe structure, and large surface area. It could attain 10 mA cm2 at 1.41 Vwhen utilized as a urea oxidation reaction anode, which is lower than the oxygen evolution reaction. For total water splitting and urea oxidation process, NiS@Ni2P as a bifunctional catalyst holds tremendouspromise due to its strong electrocatalytic activity, ease of manufacture, and low cost of raw ingredients.

Quantum Coherent Dissociation in a Hybrid Atom-light System with Photon Loss
Xiaoyang Yuan,Jialu Yin,Jiahao Xu,Yixiao Huan,Zhengda Hu 한국광학회 2024 Current Optics and Photonics Vol.8 No.1
We investigate the effect of photon loss on pair production in a hybrid atom-light system. The loss of light field not only affects the generation of photons, but also prevents the generation of atomic collective excitation, although the atoms are not influenced directly. We propose an unbalanced homodyne detection of the number of atomic collective excitation that overcomes the challenge caused by counting uncertainty in practical measurement. In discussion, we show that the intermode correlations and the number correlation is closely related to the initial input state, while the quadrature correlations are independent of the initial state and always exhibit opposite intermode correlations even in the presence of loss.
