Abstract Achieving efficient blue electroluminescence (EL) remains the fundamental challenge that impedes perovskite light‐emitting diodes (PeLEDs) towards commercial applications. The bottleneck accounting for inefficient PeLEDs is broadly attributed to poor‐emissive emitters based on either mixed halide engineering or reduced‐dimensional strategy. Herein, we report high‐performing sky‐blue (490 nm) with maximum EQE exceeding 15 % by incorporating a molecular modifier, namely...
Gastric cancer (GC) is one of the most common malignancies in Asian areas. PIEZO1 has been implied to regulate epithelial homeostasis play an important role physiological processes. It also related tumor initiation and progression. However, not yet explored GC. The expression GC cell lines primary samples was determined by qRT-PCR Western blot. clinical correlation evaluated immunohistochemistry on tissue microarray. oncogenic demonstrated gastric tumorigenesis through a series functional...
Despite recent encouraging developments, achieving efficient blue perovskite light-emitting diodes (PeLEDs) have been widely considered a critical challenge. The efficiency breakthrough only occurred in the sky-blue region, and device performance of pure-blue deep-blue PeLEDs lags far behind those their counterparts. To avoid negative effects associated with dimensionality reduction excess chloride typically needed to achieve emission, here we demonstrate guanidine (GA+)-induced (∼457 nm)...
Abstract The main reason for large energy loss in all‐inorganic perovskites is ascribed to the slow nucleation and fast crystallization of perovskite films. Herein, a manipulating strategy demonstrated simultaneously realize rapid crystal growth CsPbI 3 films by employing solvent molecular sieves antisolvent. First, antisolvent treatment mixed chlorobenzene ethyl alcohol can induce instantaneous supersaturation achieve nucleation. Subsequently, layer phthalimide (2‐N) molecules on surface be...
Mixed halide (Br/Cl) perovskite nanocrystals (NCs) that represent an advanced blue emitter commonly suffer from spectral instability and poor lifespan; notably, the lack of understanding failure mechanisms these devices has restricted future progress. Here, we determine degradation CsPbBrxCl3–x NCs containing light-emitting diodes (LEDs) is due to combination two effects. Cl– drift among adjoining under electric field found induce a Cl-deficient material region in multiple NC layers, which...
Abstract Metal halide perovskites are ideal candidates for indoor photovoltaics (IPVs) because of their easy‐to‐adjust bandgaps, which can be designed to cover the spectrum any artificial light source. However, serious non‐radiative carrier recombination under low illumination restrains application perovskite‐based IPVs (PIPVs). Herein, polar molecules amino naphthalene sulfonates employed functionalize TiO 2 substrate, anchoring CsPbI 3 perovskite crystal grains with a strong ion–dipole...
Abstract Unreacted/excess lead iodide is considered to be the archcriminal for rapid degradation of hybrid perovskite solar cells. Meanwhile, a high‐quality film with uniform and large grain size basis high‐performance modules. Herein, dual‐site molecular additive 4‐Aniline Sulfonic Acid (4A) developed regulate unreacted/excess PbI 2 passivate defects through hydrogen bonding intermolecular interactions between amino, sulfate groups , respectively. Furthermore, introduction 4A can induce...
At present, there is still a lack of in-depth research into the relationship between structural changes during healing process and self-healing efficiency polymers. In current work, molecular dynamics (MD) simulations machine learning methods were applied to investigate microscopic mechanisms in Based on MD simulations, it was found that chain segments entire chains diffuse crack region healing, together with reformation reversible interactions. Segment diffusion closely related...
Granular samples are often used to characterize the pore structure of shale. To systematically analyze influence particle size on characteristics, case studies were performed two groups organic-rich deep shale samples. Multiple methods, including small-angle neutron scattering (SANS), low-pressure nitrogen gas adsorption (LP-N2GA), carbon dioxide (LP-CO2GA), and XRD analysis, adopted investigate how crushing process would affect parameters fractal features The research indicates that with...
Abstract Compared with green and red perovskite light‐emitting diodes (PeLEDs), the development of blue PeLEDs has been lagging due to high defect density inferior carrier transport. Herein, a novel defect‐passivation strategy is proposed fabricate efficient sky‐blue by using isocyanate molecules. This not only significantly reduces nonradiative recombination loss caused defects but also improves injection transport capacities carriers reducing confinement effect. Benefiting from passivation...
