The surface defects of the organometallic perovskite play an important role in photovoltaic performance solar cells, which depress conversion efficiency and cause photocurrent hysteresis.
Single-atom catalysts (SACs) hold great promise in oxygen evolution reactions due to their ultrahigh atomic utilization rates and uniform active sites. The performance of SACs is closely related the spatial distributions single atoms on supports. However, modulating supports extremely challenging. Herein, we precisely anchored Ir onto face sites (Ir1/F-CoOOH) edge (Ir1/E-CoOOH) CoOOH. with distinct CoOOH exhibited different electronic structures but nearly identical coordination...
The large-scale development of onshore shale oil is not only an inevitable choice under the current and gas resource endowment in China but also a vivid practice to ensure national energy security. CO2 Huff-n-Puff method, as one main ways enhance recovery factor oil, has broad application prospects. In view complex interaction mechanism CO2-hydrocarbon system nanospace, which still poorly understood lacks experimental means, this paper designs two types terminal-closed single tubes porous...
The advantages of both doping chloride and using dimethylsulfoxide (DMSO) as solvent are combined, by which the performance as-prepared perovskites solar cells is significantly improved.
The introduction of PEA insert layer effectively mitigates the degradation perovskite homojunction caused by diffusion and migration ions between n-type p-type layers.
The development of a fast in situ optical sensor based on continuous-wave quantum cascade laser operating at 8 μm for the measurement environmental gaseous nitrous acid (HONO) is reported. A strong absorption line 1252.2109 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> found to be free interferences and used first time ambient HONO detection. Loss wall gas sample cell evaluated. resulting 1-s detection limit 110 pptv with folded...
The random noise and the slow drift, which respectively limit signal-to-noise ratio long-term stability, of a wavelength modulated tunable diode laser absorption spectroscopy system, are critically analyzed evaluated experimentally. sources considered in detail include contributions from lock-in amplifier, detector-preamplifier combination noise, excess DFB laser, detection cell instabilities, especially multiple reflection long-path cells. We also analyze to drift find that may be...
With the increase in number of oil and gas pipelines laid China, more attention needs to be paid pipeline maintenance work. At present, main methods detecting natural leaks transmission stations include manual inspections, opposing detection equipment, cloud desktop equipment. Hand held equipment is used for inspection, which requires regular inspection. However, response speed poor cannot detected a timely manner. The opposed laser method can only detect presence on beam path. If larger...
The use of phase-sensitive optical time-domain reflectometry (Φ-OTDR)-distributed fiber vibration sensors to detect and identify damaged bags in bag dust collectors has the potential overcome inadequacy traditional detection methods. In our previous study, we verified feasibility applying this technique field filters. However, many problems still occur engineering applications when using technology filter pulse-jet dust-cleaning collectors. Further studies are needed characterize signals...
The carbon dioxide, sulfur and metal ions produced by straw burning can severely pollute the atmosphere; thus, online detection traceability for is very important. However, to our best knowledge, there no comprehensive system that satisfy detection, classification, due challenging of burning. In this paper, a new based on laser-induced breakdown spectroscopy (LIBS) machine learning developed, developed employed first time in combustion. Four different types are selected smoke monitored using...
