Abstract Polymerization of Y6-type acceptor molecules leads to bulk-heterojunction organic solar cells with both high power-conversion efficiency and device stability, but the underlying mechanism remains unclear. Here we show that exciton recombination dynamics polymerized acceptors (Y6-PAs) strongly depends on degree aggregation. While fast rate in aggregated Y6-PA competes electron-hole separation at donor–acceptor (D–A) interface, much-suppressed dispersed is sufficient allow efficient...
The meta-stable active layer morphology of organic solar cells (OSCs) is identified as the main cause rapid burn-in loss power conversion efficiency (PCE) during long-term device operation. However, effective strategies to eliminate associated mechanisms from initial stage operation are still lacking, especially for high-efficiency material systems. Herein, introduction molecularly engineered dimer acceptors with adjustable thermal transition properties into OSCs serve supramolecular...
Abstract Soil erosion is a severe problem hindering sustainable agriculture on the Loess Plateau of China. Plot experiments were conducted under natural rainfall condition during 1995–1997 at Wangdongguo and Aobao catchments in this region to evaluate effects various land use, cropping systems, slopes runoff sediment losses, as well differences catchment responses. The included surface conditions ranging from bare soil vegetated surfaces (maize, wheat residue, Robinia pseudoacacia L.,...
Robots are now widely used in product disassembly lines, which significantly improves end-of-life (EOL) efficiency. Most of the current research on line balancing problems focuses decomposing one product. More than can be disassembled concurrently, further improve Moreover, uncertainty such as depreciation EOL products, may result failure. In this research, a stochastic multi-product robotic model is established using an AND/OR graph. It takes precedence relationship, cycle constraint, and...
Soil water retention curve is necessary for many studies of and solute transport in soils. Among the developed mathematical models, one most widely used models to describe water-retention soils van Genuchten model. Its four parameters are key application this In study we introduced detail parameter estimation procedure model using DPS system based on data (namely soil suctions corresponding contents cinnamon northeastern China), obtained values parameters. The content calculated by...
Tree diameter distribution models are important tools for forest management decision making. Soil variables affect tree growth and thus distribution. However, few studies have been conducted on describing the effects of soil. This study developed a soil-sensitive model based 213 sample plots Larix principis-rupprechtii plantations in northern China. The Weibull was modified by compatible simultaneous system percentile method with inclusion soil variables. most significant factors influencing...
For the first time, a novel fluorescent material, composed of CeO2/ANS nanocomposites was successfully synthesized by simple ultrasonic method, using CeO2 nanoparticles and 8-anilino-1-naphthalenesulfonic acid (ANS) as raw materials. The samples were characterized scanning electron microscope (SEM), photoluminescence spectroscopy Fourier transformation infrared (FTIR). results showed that PL intensity higher than both ANS powders, peak wavelength also different from typical each used...
Near-infrared (NIR) spectroscopy was applied to reagent-free quantitative analysis of polysaccharide a brand product proprietary Chinese medicine (PCM) oral solution samples. A novel method, called absorbance upper optimization partial least squares (AUO-PLS), proposed and successfully the wavelength selection. Based on varied partitioning calibration prediction sample sets, parameter performed achieve stability. On basis AUO-PLS selected bound appropriate 1.53 corresponding wavebands...
