Exploring the impact of active site density on catalytic reactions is crucial for reaching a more comprehensive understanding how single-atom catalysts work. Utilizing functional theory calculations, we have systematically investigated neighboring effects between two adjacent Fe-N-C sites monodispersed oxygen reduction reaction (ORR). While thermodynamic limiting potential (UL) strongly dependent intersite distance and nature in FeN3, it almost invariable FeN4 until are ∼4 Å apart. Further,...
Graphene has been widely studied as an electrocatalyst for hydrogen evolution reaction (HER). However, pure flat graphene is catalytically inert in HER. In this work, we investigate the effect of curvature on improvement catalytic activity and doped graphenes. We find that HER performance can be dramatically improved waved-graphene due to localized chemical potential Pt-analogous achieved at suitable compression. (1) For graphene, calculated increases more than 50% tuned by reduced Gibbs...

With the sensor scaling of next-generation Brain-Machine Interface (BMI) systems, massive A/D conversion and analog multiplexing at neural frontend poses a challenge in terms power data rates for wireless implantable BMIs. While previous works have reported neuromorphic compression signal, further requires integration spike detectors on chip. In this work, we propose an efficient HRAM-based detector using In-memory computing compressive event-based frontend. Our proposed method involves...
Point clouds or depth images captured by current RGB-D cameras often suffer from low resolution, rendering them insufficient for applications such as 3D reconstruction and robots. Existing point cloud super-resolution (PCSR) methods are either constrained geometric artifacts lack attention to edge details. To address these issues, we propose an edge-guided geometric-preserving (EGP3D) method tailored cameras. Our approach innovatively optimizes the with constraint on a projected 2D space,...
Unmanned vehicles detect the traffic environment through on-board sensors, automatically identify road safety information without human control, and plan parameters such as driving speed route.However, foggy weather will reduce detection accuracy of visibility by unmanned affect vehicles.In order to probability dangerous accidents caused fog improve vehicle capability in environments, a fast-guided-filtering algorithm is proposed.Firstly, original image processed dark channel prior, values...
