Metal halide perovskites have received much attention for their application in light-emitting diodes (LEDs) the past several years. Rapid progress has been made efficient green, red, and near-infrared perovskite LEDs. However, development of blue LEDs is still lagging far behind. Here, we report sky-blue by rearranging low-dimensional phase distribution quasi-2D perovskites. We incorporated sodium ions into mixed-Cl/Br with phenylethylammonium as organic spacer cesium lead inorganic...
Reservoir stability is a key factor in the production of natural gas hydrate (NGH), and also prerequisite to ensuring safe efficient NGH production. However, it has been rarely discussed. To analyze reservoir process by depressurization Shenhu area South China Sea, we established 3D geological model on basis drilling data this area, which was then discretized means nonstructural grid. Then, mathematical coupling four fields (i.e. thermal, hydraulic, solid chemical) considering heat mass...
Abstract CsPbI 3 is attractive for efficient and cost‐effective red perovskite light‐emitting diodes (PeLEDs), but its black phases still suffer from the metastable structure. The incorporation of large‐size organic cations has been widely used to construct quasi‐2D perovskites stabilize phases. However, multiple‐phase usually show abundant interface defects enhanced Auger recombination, leading low luminance serious efficiency roll‐off in PeLEDs. Herein, highly PeLEDs are demonstrated with...
Metal halide perovskites, a cost-effective class of semiconductos, hold great promise for display technologies that demand high-efficiency, color-pure light-emitting diodes (LEDs). Early research on three-dimensional (3D) perovskites showed low radiative efficiencies due to modest exciton binding energies. To inprove luminescence, reducing dimensionality or grain size has been common approach. However, dividing the perovskite lattice into smaller units may hinder carrier transport,...
Carbon capture and storage (CCS) is a key technology to control emissions of CO2 mitigate climate change. Coinjection with major impurity (i.e., N2 or O2) into saline aquifers would be an economical strategy. To assess the feasibility coinjection, partitioning efficiency impure in deep aquifer were numerically investigated using two-dimensional (2-D) radial anisotropic model, condition referred that Shenhua CCS site Ordos Basin. The results indicated high concentration moderately accelerated...
Horizontal and multilateral well EGSs can potentially achieve the high-heat extraction of HDR. Herein, performance a horizontal system in geothermal exploitation was investigated based on geological conditions Qiabuqia field. The target reservoir is granitic basement at 2650–3650 m depth, with initial temperatures 151–190 °C. simulation results indicate that production temperature electric power reached 178.4 °C 2.90 MW decreased by 8.3% 17.9% over 20 years under scheme injecting 60 cold...
Abstract Storage strata are usually generalized as horizontal when using numerical simulation methods to analyze CO 2 geological storage in saline aquifers. However, not common nature. Most have gradients, because of the effects structure and diagenesis. Based on actual dip angle variation range two injection demonstration projects China, five modeling schemes were designed investigate impact formation amount space migration gas‐phase reservoir formation. The results show that total is...
Quasi-2D metal halide perovskites are promising candidates for light-emitting applications owing to their large exciton binding energy and strong quantum confinement effect. Usually, quasi-2D composed of multiple phases with various numbers layers (n) octahedron sheets, enabling light emission from the lowest-bandgap phase by cascade transfer. However, transfer processes extremely sensitive distribution trap density in perovskite films, insufficient between different-n defect-induced traps...
Two homopolymers of triphenylamine and carbazole grafting silafluorenes (<bold>PSF-TPA</bold>and<bold>PSF-Cz</bold>) were synthesized their electroluminescence properties investigated in this paper.
Gas from natural gas hydrate (NGH) is priced competitively with prices. Most marine NGH stored in low cementing strata, which easily cause sand production problems, restricting the commercial and environmental safety of NGH’s development. This study applied a numerical simulation on hydrate-bearing sediments’ (HBS) exploitation. The was carried out for different productions laboratory results show radial strain appeared to be deformed away wellbore displacement close during mining. Due...
