AbstractBarrier detectors such as nBn and pBp architectures (formed by a n- or p-type contact layer, a barrier layer and a n- or p-type absorber) aim to block one carrier type while allowing the other to pass, but require complex hetero-integration and precise band engineering. Here, we propose an ultra-thin polar barrier strategy using a 0.75 nm water-intercalated WSe2/H2O/PdSe2 heterostructure.

1. IntroductionAccording to statistics provided by the International Energy Agency (IEA), in 2022, private cars and vans were responsible for over 25% of global oil consumption and approximately 10% of global energy-related CO2 emissions. To reduce greenhouse gas emissions, a growing array of countries are implementing carbon neutrality initiatives and other climate change actions [1].

AbstractAmbient-condition acetylene hydrogenation to ethylene (AC-AHE) is a promising process for ethylene production with minimal additional energy input, yet remains a great challenge due to the difficulty in the coactivation of acetylene and H2 at room temperature. Herein, we report a highly efficient AC-AHE process over robust sulfur-confined atomic Pd species on tungsten sulfide surface.

AbstractTo optimize the current college sports data information management system, this study combines the Apriori association rule algorithm with web application development technology to upgrade the management system. Firstly, this study explores novel log mining techniques in genetic algorithms and web application development technology. Secondly, by integrating log mining techniques to optimize the Apriori algorithm, associations between sports data and information are discovered.

AbstractThe reverse water gas shift reaction can be considered as a promising route to mitigate global warming by converting CO2 into syngas in a large scale, while it is still challenging for non-Cu-based catalysts to break the trade-off between activity and selectivity.

1. IntroductionIntegrated sensing technology for space–air–ground–ocean (SAGO) contexts is a key research focus for next-generation mobile communications [1]. Underwater communication technology plays a crucial role in SAGO integrated sensing and information transmission systems. Acoustic waves are the sole effective medium for long-range underwater information transmission.

AbstractOxygen vacancy (Ov) is an anionic defect widely existed in metal oxide lattice, as exemplified by CeO2, TiO2, and ZnO. As Ov can modify the band structure of solid, it improves the physicochemical properties such as the semiconducting performance and catalytic behaviours. We report here a new type of Ov as an intrinsic part of a perfect crystalline surface.
