Electrochemical nitrate reduction to ammonia(NRA) can realize the green synthesis of ammonia(NH3) at ambient conditions, and also remove nitrate contamination in water. However, the current catalysts for NRA still face relatively low NH3yield rate and poor stability. We present here a core-shell heterostructure comprising cobalt oxide anchored on copper oxide nanowire arrays(CuO NWAs@Co_(3)O_(4)) for efficient NRA. The CuO NWAs@Co_(3)O_(4)demonstrates significantly enhanced NRA performance in alkaline media in comparison with plain CuO NWAs and Co_(3)O_(4)flocs. Especially, at-0.23 V vs. RHE, NH_(3) yield rate of the CuO NWAs@Co_(3)O_(4)reaches 1.915 mmol h^(-1)cm^(-2),much higher than those of CuO NWAs(1.472 mmol h^(-1)cm^(-2)), Co_(3)O_(4)flocs(1.222 mmol h^(-1)cm^(-2)) and recent reported Cu-based *** is proposed that the synergetic effects of the heterostructure combing atom hydrogen adsorption and nitrate reduction lead to the enhanced NRA performance.

Surgical smoke can obscure the surgeon's line of sight during the laparoscopic procedure, potentially posing risk to the patients. Robot assisted-minimally invasive surgery (MIS) also faces such a challenge, which also hinders its autonomous operation. This paper proposes a desmoking method for laparoscopic surgery smoke removal. As the surgical smoke is hetergeneous, a two-stage network is developed to estimate the smoke distribution and reconstruct the corresponding smoke-free scene with the hybrid embedding guidance, including the estimated smoke mask and the initial image. The network is designed following the concept of the atmospheric scattering model, which makes the network more explainable. To qualitatively and quantitatively evaluate the proposed method, a synthetic laparoscopic dataset is generated and a real laparoscopic dataset is obtained. Experimental results show that the Peak Signal to Noise Ratio (PSNR) of the proposed method is 1.9% higher than that of the DehazeFormer, while the run-time is shorter more than 40.9%. The proposed method is comparable to or even outperforms the state-of-the-arts in desmoking quality and computation cost. © 2024 IEEE.

ZnS crystal is a multispectral infrared optical material with excellent optical and mechanical properties. Due to its large brittle properties, low hardness, and poor machining performance, Single Point Diamond Ultra Precision Turning technology (SPDT) is the effective fabrication method for ZnS at present. However, the machining accuracy of the SPDT method is limited by the principle of "error copying", which cannot meet the application of high precision applications. Moreover, the traditional polishing method cannot achieve the high efficiency of surface shape accuracy and surface quality improvement of aspherical elements. In order to meet the demands of high precision surface shape and high surface quality of ZnS aspherical optical components, a new combined polishing technology which consists of Magnetorheological Finishing (MRF) and Small Tool Polishing (STP) technology is presented and researched in this paper. Firstly, the Magnetorheological Finishing method is used to achieve the deterministic convergence of surface figure error rapidly. The quantified relationship between process parameters and process defects is established through a series of experiments. Through the optimization of MRF polishing fluid and processing parameters, the surface quality is controlled from sharp deterioration while removing the cutting knife lines. Then STP method is used to improve the surface quality while maintaining the surface figure accuracy. This combined polishing technology is conducted through validation experiments on the ZnS experimental sample. The surface figure error is reduced by 3 times after polishing and the surface roughness is below Ra 1nm. This result validates the effectiveness of the combined polishing technology proposed in the paper. © 2024 SPIE.
