Sufficient lead iodide (PbI2) in perovskite films effectively passivates defects and enhances device performance. However, excess large-grained PbI2 clusters tend to be randomly distributed the layer, which mitigate positive effect of PbI2. Here, we first modulated distribution size by functionalizing buried interface 4,4′-diaminodiphenyl sulfone hydroiodide (DDSI2). As a multifunctional modifier, DDSI2 can optimize energy level tin oxide (SnO2) passivate via −NH3+ S═O functional groups....
Abstract Molecular modulators have been demonstrated to be an effectual strategy for reducing the defect at interface and in bulk of perovskite ameliorating performance stability solar cells (PSCs). Herein, 1‐aza‐15‐crown 5‐ether (A15C5), with a unique nitrogen heterocyclic structure as molecular modulator is introduced between layer hole transport PSCs. Multiple supramolecular synergistic interaction A15C5 dramatically suppress passivate defects, resulting 38% decrease electron trap‐state...
Functional magnetic resonance imaging has been widely used to investigate the effects of acupuncture on neural activity. However, most functional studies have focused acute changes in brain activation induced by acupuncture. Thus, time course therapeutic remains unclear. In this study, 32 patients with amnestic mild cognitive impairment were randomly divided into two groups, where they received either Tiaoshen Yizhi or sham acupoint The needles twirled at acupoints, including Sishencong...
Semitransparent solar cells have attracted significant attention for their potential applications, though obtaining high average visible transmittance (AVT) while maintaining good conversion efficiency is a challenge.
In recent years, carbon-based CsPbI2 Br perovskite solar cells (PSCs) have attracted more attention due to their low cost and good stability. However, the power conversion efficiency (PCE) of PSCs is still no than 16%, because defects in or at interface with electron transport layer (ETL), as well energy level mismatch, which lead loss energy, thus limiting PCE values. Herein, a series cadmium halides are introduced, including CdCl2 , CdBr2 CdI2 for dual direction thermal diffusion...
Alloy-type anodes are considered promising candidates in sodium-ion batteries (SIBs) due to their high theoretical capacities, low discharge plateaus, and abundant resources. However, the significant volume changes during discharging/charging result...
Introduction Skin aging is an inevitable physiological process driven by factors like cellular senescence, ultraviolet radiation (UV) radiation, and environmental pollutants. A key feature the accelerated collagen degradation in dermal extracellular matrix, leading to visible signs such as sagging, wrinkles, hyperpigmentation. Traditional fillers, hyaluronic acid collagen-based offer only temporary volume enhancement without stimulating regeneration. Studies have shown that electrical...
Abstract Favorable stability is a big challenge for the commercialization of perovskite solar cells, and all‐inorganic semiconductors have attracted much attention due to their excellent performance in this field. In reality, poor mainly high‐density defects films, which provide channel charge nonradiative recombination ion migration. work, multifunctional aminoguanidine hemisulfate (AG HSUL) introduced into CsPbIBr 2 layer achieve defect passivation. Guanidine cations (GA + ) can form...
The carrier non-radiative recombination and instability of device caused by the inherent defects are main factors limiting development perovskite solar cells (PSCs). During fabrication process a PSC device, films often produce Pb0 I0 defects. This paper reports strategy for synergistic optimization passivation surface modification. doping phthalide (PT) in Pb-rich (CH(NH2 )2 )1-x (CH3 NH3 )x PbI3 film can passivate lead cation defects, modification 1-iodooctadecane (1-IO) reduce halogen...
The rapid development of perovskite solar cells (PSCs) makes it one the most competitive photovoltaic devices in field new energy. However, suboptimal performance and poor stability caused by numerous defects are still main factors limiting PSCs. Herein, a polarized molecule additive 4-(aminomethyl) benzonitrile hydrochloride (AMBNCl) is introduced into perovskite. Owing to its special polar electron density distribution, −C≡N group, −NH3+ terminal, Cl– ions, modification AMBNCl can improve...
Background Acute kidney injury (AKI) has been recognized as a major healthcare problem affecting millions of patients worldwide. However, epidemiologic data concerning AKI in China are still lacking. The objectives this study were to characterize defined by RIFLE criteria, assess the association with hospital mortality, and evaluate impact context other risk factors. Methods This prospective multicenter observational enrolled 3,063 consecutive from 1 July 2009 31 August 22 ICUs across...
Abstract Inorganic cesium lead halide perovskite solar cells have attracted widespread attention owing to their excellent stability relative organic–inorganic cells. However, all‐inorganic without hole transport layers and using carbon as electrodes serious energy level mismatch problems. To overcome this problem, here, the CsPbIBr 2 surface is treated with 4‐aminomethyltetrahydropyran acetate form a gradient band on perovskite/carbon interface. As result, extraction efficiency successfully...
