Abstract In the field of perovskite light-emitting diodes (PeLEDs), performance blue emissive electroluminescence devices lags behind other counterparts due to lack fabrication methodology. Herein, we demonstrate in situ CsPbClBr 2 nanocrystal films by using mixed ligands 2-phenylethanamine bromide (PEABr) and 3,3-diphenylpropylamine (DPPABr). PEABr dominates formation quasi-two-dimensional perovskites with small- n domains, while DPPABr induces large- domains. Strong emission at 470 nm a...
Quasi-2D perovskites, composed of self-organized quantum well structures, are emerging as gain materials for laser applications. Here we investigate the influence domain distribution on emission CsPbCl1.5Br1.5-based quasi-2D perovskites. The use 2,2-diphenylethylammonium bromide (DPEABr) a ligand enables formation film with large-n-dominated narrow distribution. Due to reduced content small-n domains, incomplete energy transfer from large-n domains can be greatly addressed. Moreover,...
Abstract The performance of tin (Sn)‐based perovskite light‐emitting diodes (PeLEDs) lags behind their lead analogs due to the challenges Sn 2+ oxidation, defect passivation, and fast crystallization. Herein, passivation effects diphenylphosphine oxide (DPPO) derivatives on fabrication PEA 2 SnI 4 films are investigated. DPPO with hydroxyl group, or including substituent group potential form unfavorable passivators positive in accelerating oxidation. In comparison, amino‐functionalized...
Recently, electrocatalysts based on anchored dispersive/isolated single metal atoms conductive carbon supports have demonstrated great promise to substitute costly Pt for the oxygen reduction reaction (ORR) in field of fuel cells or metal-air batteries. However, developments cost-efficient single-atom Fe catalysts with high activities are still facing various hardships. Here, we developed a facile way synthesize isolated iron nanotube (CNT) involving one-pot pyrrole polymerization...
Abstract In recent years, the field of metal-halide perovskite emitters has rapidly emerged as a new community in solid-state lighting. Their exceptional optoelectronic properties have contributed to rapid rise external quantum efficiencies (EQEs) light-emitting diodes (PeLEDs) from <1% (in 2014) over 30% 2023) across wide range wavelengths. However, several challenges still hinder their commercialization, including relatively low EQEs blue/white devices, limited large-area poor device...

In this work, the solvent effects of on‐chip crystallization investigated by correlating nucleation and growth process formamidinium lead iodide (FAPbI 3 ) with their optical electronic properties. FAPbI from γ‐butyrolactone (GBL) smaller than those N , ‐dimethylformamide dimethyl sulfoxide, relatively...
Abstract Photoelectric properties of all-inorganic perovskite quantum dots (IPQDs) highly depend on their synthetic route. However, current processes IPQDs are widely facing potential unsustainable issues containing nonreusable and high-cost auxiliary materials. In this work, full-visible-spectrum were successfully synthesized by an environmentally friendly ion-exchange approach with a renewable low-cost anion exchange resin. Introducing resin brings the improvement both optical performance...
Abstract Lithium (Li) metal is widely recognized as a viable candidate for anode material in future battery technologies due to its exceptional energy density. Nevertheless, the commercial Li foils common use are too thick (≈100 µm), resulting waste of resources. Herein, by applying vacuum evaporation plating technology, ultra‐thin (VELi) with high purity, strong adhesion, and thickness less than 10 µm successfully prepared. The manipulation temperature allows convenient regulation...
This study aims to provide a reference for clinical treatment selection by comparing noninvasive ventilation (NIV) and high-flow nasal cannula (HFNC) oxygen therapy in patients with chronic obstructive pulmonary disease (COPD) complicated community-acquired pneumonia (CAP). From January 2022 December 2023, 63 COPD CAP treated at our hospital were enrolled. Patients allocated either the NIV group (33 patients) or HFNC (30 patients), addition receiving conventional treatments. The groups...
In this paper, the mechanical properties of steel fiber reinforced alkali-activated cementitious materials are introduced. The results show that appropriate proportion long and short is better than single or to enhance splitting tensile strength concrete. This may be because fibers can effectively inhibit expansion microcracks macrocracks, respectively.
With the development of Internet things (IoT) technology and smart grid infrastructure, edge computing has become an effective solution to meet delay requirements electric power IoT. Due limitation battery capacity data transmission mode IoT terminals, business collaboration must consider energy consumption terminals. Since are optimization goals two co-directional changes, it is difficult find a mechanism that simultaneously minimizes consumption. This paper takes unmanned aerial vehicle...
Abstract Exciplex‐forming cohosts have gained increasing interest due to their promising performances in organic light‐emitting diodes (OLEDs). Such electroluminescent stabilities of the exciplex depend on charge‐carrier recombination. But intrinsic relationships between recombination schemes and electrical aging process are yet be revealed. In this case, with two different schemes, namely trap‐assisted (TAR) trimolecular Langevin (LR), compared. The LR‐dominated device achieves T 90...
