Currently, the implantation and health treatment of electronic devices based on adhesion and flexible substrates are widely studied. However, these adhesive layers are usually non-conductive, and how to achieve stable electrical conductivity on flexible substrates remains challenging. Here, a...

Exploitation of oxygen evolution reaction (OER) and urea oxidation reaction (UOR) catalysts with high activity and stability at large current density is a major challenge for energy-saving H2 production in water electrolysis. Herein, we successfully use the NiFe2O4 nanosheet to activate the...

Transition metal sulfide is a promising electrocatalyst for the hydrogen evolution reaction (HER), yet it is still uncompetitive with platinum-based electrodes for clean and renewable energy applications. To resolve this issue, grid-matched palladium-nickel sulfides (Pd4S/Ni3S2) are successfully...

Platforms compete intensively to attract users. Monetary subsidies are commonly used to incentivize users’ adoption, but such subsidies are expensive. In this paper, we study the impacts of token incentives, an alternative incentive approach, in the competition of two decentralized exchange...

Purpose The purpose of this paper is further leveraging the advantages of the basic socialist economic system and exploring the realistic way of transforming the advantages of the socialist economic system with Chinese characteristics into governance efficacy. At its Fourth Plenary Session, the...

We investigate the joint effects of analyst reputation, uncertainty, and guidance news valence on analysts’ reliance on management guidance. We find that, compared to less reputable analysts, reputable analysts rely less on guidance when they issue earnings forecasts. This analyst reputation...
