Water-Driven Stacking Structure Transformation of Ultrathin Ru Nanosheets for Efficient Hydrogen Evolution Reaction.

Ultrathin crystalline materials are a class of popular materials that can potentially exhibit fascinating physical and chemical properties dictated by their unique stacking freedom. However, it is challenging to achieve the controllable synthesis over their stacking structure for ultrathin crystalline materials. Herein, water is employed as a key regulatory factor to realize phase engineering in ultrathin nanosheets (NSs), thereby altering stacking faults to achieve distinct stacking arrangements.

Adsorption Mechanisms of TM (TM = Mo, Ru, Au)-Decorated Tin Sulfide Monolayers for the Decomposition of Gas Components under Fault Conditions in Oil-Immersed Transformers.

Oil-immersed transformers play a pivotal role owing to their environmentally friendly characteristics, compact footprint, and cost-effectiveness. Ensuring the online monitoring of oil-immersed transformers is a fundamental measure to ensure the secure and stable operation of modern power systems. In this paper, metal particle cluster-doped SnS is firstly used in the adsorption and sensing of decomposition components (CO, CH) under fault conditions in oil-immersed transformers.

An effective planning approach for integrated energy systems considering equipment operating characteristics.

Aiming at the accuracy of modeling in existing integrated energy system planning methods, a comprehensive energy system p lanning method that takes into account the actual operating efficiency of the system is proposed. First, the output model of various equipment units based on the basic structure of the integrated energy system is established. Then, based on the traditional energy hub model, a correction model for the work efficiency of energy equipment to construct an improved dynamic efficiency model of energy equipment is established.
