To address the CO2 accumulation in atmosphere, various initiatives have been proposed, among which capture and utilization (CCU) is regarded as an appealing strategy to reconcile carbon emission resource utilization. Especially, integrated (ICCU), i.e. performing in-situ conversion can circumvent energy-intensive desorption step thus facilitate establishing step- energy-efficient process, rendering at mild conditions particularly low pressure due substantial activation upon uptake. However,...
A Cu/Co tandem catalysis protocol was developed to conduct the hydroformylation of olefins using CO
A biotrickling filter demo has been set up in a petrochemical factory Sinopec Group for about 10 months with maximum inlet gas flow rate of 3000 m3 h(-1). The purpose this project is to assess the ability remove hardly biodegradable VOCs such as benzene, toluene and xylene which are recalcitrant poorly water soluble commonly found factories. Light-weight hollow ceramic balls (Φ 5-8 cm) were used packing media treated large amounts circulating (2.4 m(-2) h(-1)) added bacterial species....
Owing to factors such as climate change and human activities, ecological environmental problems of land desertification have emerged in many regions around the world, among which problem northwestern China is particularly serious. To grasp trend degree natural vegetation degradation northwest a basic prerequisite for managing fragile environment there. Visible light remote sensing images taken by UAV can monitor cover desert areas on large scale with high time efficiency. However, there are...
Abstract: The Longquanguan shear zone is an important structural belt in the North China Craton, separating underlying Fuping complex from overlying Wutai complex. This has experienced three episodes of deformation: first and main episode a ductile top‐to‐ESE along gently northwest‐west dipping foliations, while other two are later collapse sliding. Prolonged granites parallel to foliations make one compositions zone. These deformation form mylonitic rocks when they emplaced during...
We report AlGaN-based back-illuminated solar-blind Schottky-type ultraviolet photodetectors with the cutoff-wavelength from 280nm to 292nm without bias. The devices show low dark current of 2.1 × 10−6A/cm2 at reverse bias 5 V. specific detectivity D* is estimated be 3.3 1012cmHz1/2 W−1. To guarantee performance photodetectors, optimization AlGaN growth and annealing condition for Schottky contacts were performed. results that high-temperature method Ni/Pt effective reduction leakage current.
<abstract> The traditional signature-based detection method requires detailed manual analysis to extract the signatures of malicious samples, and a large number markers maintain signature library, which brings great time resource costs, makes it difficult adapt rapid generation mutation malware. Methods based on machine learning often require lot resources in sample labeling, results sufficient inventory unlabeled samples but not directly usable. In view these issues, this paper proposes an...
Many scientists today routinely conduct simulations and run models using high performance computing (HPC) resources provided by national, regional campus grid infrastructures, either directly logging into such or indirectly via web portals other application client software, i.e. science gateways. Science gateways have proven to be an effective way of bringing HPC a much larger user base. However, developing new gateway demands substantial effort, requiring both cyberinfrastructure domain...
Attempt to form the Schottky barrier on mercury indium telluride (MIT) surface by deposition transparent conducting electrode (TCE) and avoid negative results non-rectifier contacts nature, we have investigated oxidation of clean MIT surfaces an insulating layer overcome this disadvantage metal-insulator-semiconductor (MIS) photodetectors designing. Oxide film is grown plasma enhance chemical vapor (PECVD). Previously cleaned wafers were dipped boiled in solution, which consists mixture...
Aiming at the problem that low visible light and noise will not only reduce visual beauty of images but also cause loss important information, an improved Retinex theory method is put forward to enhance illumination images. More specifically, a analytic model applied before original image refine construct with good parameters. Finally, color recovery factor added readjust distortion caused by contrast enhancement in local region image, so as realize corresponding enhancement. Experiments on...
The Cover Feature shows a copper/cobalt tandem catalytic system for the hydroformylation of olefins with CO2 and reductants to efficiently afford aldehydes in high regioselectivity, just like two people working synergistically complete relay race. This strategy couples reduction CO subsequent achieve valorization. More information can be found Research Article by L.-N. He co-workers.
Covalent organic framework (COF), as a porous crystalline material, provides versatile platform for photocatalytic CO2 reduction reaction (PCO2RR). However, the lack of surface redox active sites and rapid photogenerated...
Clouds are environment that enable the sharing, selection, query and aggregation of geographically distributed resources for solving large-scale problems. Therefore resource schedule mechanism becomes a complex undertaking problem. We had investigated several famous methods proposed by Nimrod-G, computational economy framework regulating supply demand resources. In this paper, we propose new scheduling algorithm based on deadline cost optimization, which extends traditional optimization time...
Carrier frequency offset (CFO) between transmitter and receiver carrier generators degrade the performance of adaptive filters seriously, even for very small CFO. Tracking analysis affine projection filter is carried out in presence The energy conservation relation with both random cyclic nonstationarities derived. Based on steadystate mean-square error derived nonstationarities. theoretical results are close to Monte Carlo simulation curves. Besides, simulations show that tracking improves...
