Metal sulfides, such as MoS2, are widely investigated in lithium–sulfur (Li–S) batteries to suppress the shuttling of lithium polysulfides (LiPSs) due their chemical adsorption ability and catalytic activity. However, relatively low conductivity activity limit LiPS conversion kinetics. Herein, Co-doped MoS2 is proposed accelerate Co doping can promote transition from semiconducting 2H phase metallic 1T introduce sulfur vacancies MoS2. A one-step hydrothermal process used prepare a with more...

Abstract Lithium sulfide (Li 2 S) is a promising cathode for practical lithium‐sulfur battery as it can be coupled with various safe lithium‐free anodes. However, the high activation potential (>3.5 V) together shuttling of lithium polysulfides (LiPSs) bottleneck its uses. We are trying to present catalysis solution solve both problems simultaneously, specially twinborn heterostructure shoot off trouble in interfacial contact between two solids, catalyst and Li S. As typical example, Co 9...

Sparse triangular solve (SpTRSV) is one of the most important kernels in many real-world applications. Currently, much research on parallel SpTRSV focuses level-set construction for reducing number inter-level synchronizations. However, out-of-control data reuse and high cost global memory or shared cache access synchronization have been largely neglected existing work.

Abstract Catalysis is an effective remedy for the fast capacity decay of lithium‐sulfur batteries induced by shuttling lithium polysulfides (LiPSs), but too strong adsorption ability many catalysts toward LiPSs increases risk catalyst passivation and restricts diffusion conversion. Herein, perovskite bimetallic hydroxide (CoSn(OH) 6 ) nanocages are prepared, which further wrapped reduced graphene oxide (rGO) as catalytic host sulfur. Because coordinated valence state Co Sn intrinsic defect...

Abstract Chemical tracer testing technology is one of the important means for reservoir characterization. By injecting chemical tracers, effective information under specific conditions can be obtained, such as inter-well connectivity between injection and production wells, evaluation enhanced oil recovery after polymer injection, estimation residual saturation. In this study, fluorescent silica nanoparticles were selected tracers. Through core displacement experiments, adsorption retention...
