Abstract Efficient oxygen evolution reaction (OER) electrocatalysts play a pivotal role in water electrolysis, notably for industrial high current densities (>1000 mA cm −2 ). Crystalline/amorphous heterostructure interfaces have proven to be advantageous enhancing the OER activities of electrocatalytic materials. However, constructing and tailoring crystalline/amorphous still remain great challenge due destruction active substrates by intricate post‐treatment. Here, strategy tailor...

How to reduce the content placement cost of cloud delivery networks (CCDNs) is a hot topic in recent years. Traditional methods mainly by constructing trees, but they cannot adapt dynamic deployment proxy servers CCDNs. In addition, traditional method only provides paths according local decision-making without considering global dynamics congestion CCDNs, which also one main factors causing high placement. To solve these problems, we propose model based on Q-learning for called Q-content...
