Photoelectrochemical water splitting to generate H2 and O2 using only photon energy (with no added electrical energy) has been demonstrated with dual n-type-semiconductor (or Z-scheme) systems. Here we investigated two different Z-scheme systems; one is comprised of cells the same metal-oxide semiconductor (W- Mo-doped bismuth vanadate), that is, Pt-W/Mo-BiVO4, other metal oxide a chalcogenide semiconductor, Pt-W/Mo-BiVO4 Zn(0.2)Cd(0.8)Se. The redox couples utilized in these configurations...
Abstract With the rapid development of urban transportation systems, occurrence intersections and parallels between railway lines buried gas pipelines became increasingly prevalent. The severe periodic DC stray current generated during line operations accelerates pipeline corrosion, thereby significantly impacting safety. A natural in Nanjing, China had long been affected by dynamic interference currents from subway (with a maximum density reaching 976 A/m2). existing drainage system with...
Quaternary-alloyed ZnxCd1−xSySe1−y arrays were prepared from four precursor aqueous/glycerol (3:1) solutions with a robotic piezoelectric dispenser on fluorine-doped tin oxide (FTO) conductive glass. Hydrazine (N2H4) was used for protecting the selenium source, dimethylselenourea, oxidation so that fabrication of could be carried out under ambient air conditions. The absorption spectra photocatalyst spots (230-μm size) array measured fiber-optic/CCD detector system. band gaps function...
The current mode of clinical aided diagnosis Ocular Myasthenia Gravis (OMG) is time-consuming and laborious, it lacks quantitative standards. An diagnostic system for OMG proposed to solve this problem. values calculated by the include three indicators: eyelid distance, sclera palpebra superior fatigability test time. For first two indicators, semantic segmentation method was used extract pathological features patient's eye image a model constructed. patient divided into regions: iris,...
CuInSe2 and CuInMSe2 (M = Ga, Zn, Cd) arrays were prepared from precursor aqueous:glycerol (3:1) solutions with a robotic piezoelectric dispenser on fluorine-doped tin oxide (FTO) conductive glass. Studies of the photoresponse spots array by scanning electrochemical microscopy (SECM) an optical fiber tip showed that different annealing temperatures affected position optimal spot (the highest photocurrent). Depositing thin layer CdS CIS-250 improved photoactivity also position. Adding 20−40%...
In order to understand the effect of natural environmental factors on carbon fiber/epoxy composites, degradation composite was studied. The specimens were exposed in a Xe lamp chamber and suffered ultraviolet light radiation, temperature and/or humidity conditions. results show that could cause extensive corrosion surface interior carbon/epoxy attack interface between matrix fiber, resulting an obvious reduction transverse tensile strength interlaminar shear strength. On contrary,...
Although many researches on superconducting air‐core transformers has been carried out, it is mainly the power frequency situation. The high‐frequency characteristics of are still unclear. In this paper, we applied experimental and finite element simulation approach to study operation loss high transformer made by YBCO tapes. numerical model established based H formula E‐J law, edge degradation anisotropy critical current density tape considered in model. results show that operating...
Abstract The safe and stable operation of hydraulic machinery equipment cannot be separated from various auxiliary electrical equipments lubricating oils. And these are important factors in the occurrence fire. Fire detection is used to detect fire hazards during equipment, which great significance ensuring safety reducing economic losses. Traditional methods require detector put close source, also prone interference, resulting delayed detection, false alarm missed alarm. To solve problems,...
The short-circuit fault current on the dc side affects operation safety of multiterminal flexible HVdc transmission system seriously. resistance-type superconducting limiter (RSFCL) has received extensive attention in limiting impact because it fast response speed and zero impedance at steady state. YBCO tapes are susceptible to delamination damage under large will affect RSFCLs. However, existing methods distinguishing tape need an extra observation or testing after impact. These cannot...
The short-circuit fault current on the dc side affects operation safety of multiterminal flexible HVdc (MTDC) transmission system seriously. resistance-type superconducting limiter (RSFCL) has received extensive attention in limiting impact because it a fast response speed and zero impedance at steady state. At present, there are so many works simulations RSFCLs but error is relatively larger, which design accuracy RSFCLs. In this article, characteristics limiters studied. resistance other...
Abstract Using a wireless charging method to charge high-temperature superconducting (HTS) magnets is way solve the existing problem of high leakage heat introduced by through current leads.
