Organic-inorganic halide perovskites have exhibited bright prospects in high-sensitivity X-ray detection. However, they generally suffer from the severe field-driven polarization issue that remarkably deteriorates detection performance. Here, it is demonstrated interfacial electrochemical reaction between Au electrodes and halogen MAPbI3 single crystals (SCs) major source of dark current metal-semiconductor-metal (MSM)-structured perovskite detectors at initial stage biasing. By introducing...
Organic-inorganic halide perovskites (OIHPs) are recognized as the promising next-generation X-ray detection materials. However, device performance is largely limited by ion migration issue of OIHPs. Here, we reported a simple atomistic surface passivation strategy with methylammonium iodide (MAI) to remarkably increase activation energy CH 3 NH PbI single crystals. The amount MAI deposited on crystal finely regulated self-assemble process effectively suppress metallic lead defects, while...
Flexible perovskite solar cells (FPSCs) have attracted great attention due to their advantageous traits such as low cost, portability, light-weight, etc. However, mechanical stability is still the weak point in practical application. Herein, we prepared efficient FPSCs with remarkable by a dynamic thermal self-healing effect, which can be realized usage of supramolecular adhesive. The adhesive, was obtained random copolymerization acrylamide and n-butyl acrylate, amphiphilic, has proper...
A highly crystalline tempered-glass-like perovskite grain structure with compressed surface lattice realized by a thermal-shocking fabrication is shown. The strained stabilized Cl- -reinforcing and shows enhanced bonding energy ionic activation temperature, which contributes to hysteresis-free operation of solar cells (PSCs) at much higher temperature up 363 K in thermal-shocking-processed MAPbClx I3-x (T-MPI). PSCs can be fabricated high-speed fully air process without post-annealing based...
Bright perovskite nanocrystals with high color purity are promising for high-definition displays; however, their complex postprocessing process limits large-scale production. Using a trace of octylamine to regulate the dynamic balance between surface ligand adsorption and desorption, we develop facile method obtain stable CsPbI3 nanocrystal films that combine excellent optical electrical properties. The additive maintains integrity inhibits formation defects, greatly enhances phase-...
Despite light-emitting diodes (LEDs) based on quasi-two-dimensional (Q-2D) perovskites being inexpensive and exhibiting high performance, defects still limit the improvement of electroluminescence efficiency stability by causing nonradiative recombination. Here, an organic molecule, 1-(o-tolyl) biguanide, is used to simultaneously inhibit passivate Q-2D via in situ synchronous crystallization. This molecule not only prevents surface bromine vacancies from forming through hydrogen bonding...
Previous studies have shown that prophylactic cranial irradiation (PCI) can improve the survival of patients with limited-stage small cell lung cancer (LS-SCLC). PCI is recommended for who respond well to chemoradiotherapy. However, whether could be extrapolated LS-SCLC in modern era MRI unknown. This study aimed explore value brain MRI.This included 306 at Cancer Hospital China Medical University. All received diagnosis and after radiochemotherapy exclude metastases. A propensity score...
The unprecedented performance of large language models (LLMs) necessitates improvements in evaluations. Rather than merely exploring the breadth LLM abilities, we believe meticulous and thoughtful designs are essential to thorough, unbiased, applicable Given importance world knowledge LLMs, construct a Knowledge-oriented Assessment benchmark (KoLA), which carefully design three crucial factors: (1) For ability modeling, mimic human cognition form four-level taxonomy knowledge-related...

Halide perovskites are emerging as promising candidates for white light solid state lighting. Nevertheless, there still challenges of a high water stability, tunable color temperature, and photoluminescence quantum yield (PLQY). Herein, we report hydrophobic, electron-withdrawing trifluoromethyl (-CF3)-modified phenethylamine lead bromide (PEA2PbBr4) with ultrahigh stability in >2 months, the broadband emission is illustrated by self-trapped excitons attributed to exciton–phonon coupling...

Angular distribution of protons is measured from ethanol droplet spray irradiated by linearly polarized 150 fs laser pulses at an intensity 1.1 x 10(16)W/cm2. Fast (with energies >16 keV ) with anisotropic can be observed only in or near the polarization plane fields, while slow <or=16 emit nearly isotropic distribution. Two-dimensional particle-in-cell simulations suggest that three groups originate different acceleration regimes laser-droplet interaction. The first group highest...
