Abstract Topological photonic structures exhibit resilience to defects, allowing unidirectional light flow and promoting the development of robust devices with large information processing capacities. However, diversity topological boundary modes is typically governed by bulk-edge correspondence, which limits multidimensional multiplexing integration density next-generation systems. Here, we present a polycrystal approach based on domain wall engineering configure multi-band dispersion in...
Abstract Six dust storms that originated from Mongolia and moved to northern China in Spring 2021 are investigated by the anomaly variable‐based analysis method, which is compared traditional total‐variable based method. Strong surface wind a force form as commonly known current practice. However, area depicted total‐wind model product operational forecast has large bias observation even for leading 24 hr. The method of variables showed domain an airborne storm observed satellite images...
Aerosols play an important role in global climate change, which requires long-term data records. Advanced very high-resolution radiometer (AVHRR) provides continuous observations for up to 40 years since 1979, makes it worthwhile retrieve aerosol optical depth (AOD) from AVHRR over land. A novel algorithm retrieving AOD is developed based on the machine learning (ML) method. The pathfinder atmospheres–extended (PATMOS-x) Level-2 dataset and corresponding products ( <inline-formula...
Xuan Wei area, Yunnan province of China, has one the highest lung cancer mortality rates in China. Heavy metals aerosol are potential facts that might attribute to cause cancer, and speciation heavy could play a key role toxicity metals. Therefore, we try reveal major by using synchrotron radiation techniques this study. Mass concentration chemical elements ambient particles were analyzed PIXE (Proton induced X-ray emission), Cu was investigated XAFS (X-ray absorption near-edge structure)....
Abstract Arsenic is one of the trace elements in coal that we are most concerned about because its toxicity and environmental persistence. Poisoning endemic China widespread locally very severe, which receiving increased attention throughout world. In this study, an oxidation method was applied for removing arsenic from two Chinese coals (Yima Datong) under ultrasonic microwave radiation. There many processing parameters impact effect coal: power ultrasonic, time radiation, concentration...
Abstract Two complementary methods, float-sink experiment and sequential chemical leaching were used to probe into the occurrence of arsenic in two Chinese coals: Yima (YM) Datong (DT). Flow injection-hydride generation atomic fluorescence spectrometry was employed measure content parent coals as well size density-fraction samples. Float-sink indicated that heavy density fractions enriched mineral containing bituminous studied, confirmed by method. Sequential revealed sulfide primary mode (>...
The removal of industrial dust is mainly realized by various equipment. electrostatic remover can remove more than 99.5% the particles diameters, but effect particulate not significant. Among them, for finer in dust, poor. After measurement, efficiency 80%-85% fine with a particle diameter 10-1μm [1]. With our higher demand emissions, improving particulates imminent. In process generation, collide or come into contact through paths, thereby combining to generate larger particles, and this...
