We report large-scale synthesis of silica nanowires (SiONWs) using an excimer laser ablation method. Silica was produced in the form amorphous at a diameter ∼15 nm and length up to hundreds micrometers. The SiONWs emit stable high brightness blue light energies 2.65 3.0 eV. intensity emission is two orders magnitude higher than that porous silicon. may have potential applications high-resolution optical heads scanning near-field microscope or nanointerconnections future integrated devices.
Black-phase formamidinium lead iodide (α-FAPbI 3 ) perovskites are the desired phase for photovoltaic applications, but water can trigger formation of photoinactive impurity phases such as δ-FAPbI . We show that classic solvent system perovskite fabrication exacerbates this reproducibility challenge. The conventional coordinative dimethyl sulfoxide (DMSO) promoted under high relative humidity (RH) conditions because its hygroscopic nature. introduced chlorine-containing organic molecules to...
PEDOT:PSS has been widely used as a hole extraction layer (HEL) in organic solar cells (OSCs). However, their acidic nature can potentially corrode the indium tin oxide (ITO) electrode over time, leading to adverse effects on longevity of OSCs. Herein, we have developed class biphosphonic acid molecules with tunable dipole moments for self-assembled monolayers (SAMs), namely, 3-BPIC(i), 3-BPIC, and 3-BPIC-F, which exhibit an increasing moment sequence. Compared centrosymmetric axisymmetric...
Inverted organic solar cells (OSCs) have attracted much attention because of their outstanding stability, with zinc oxide (ZnO) being commonly used as the electron transport layer (ETL). However, both surface defects and photocatalytic effect ZnO could lead to serious photodegradation acceptor materials. This, in turn, hampers improvement efficiency stability OSCs. Herein, we developed a multiarmed aromatic ammonium salt, namely, benzene-1,3,5-triyltrimethanaminium bromide (PhTMABr), for...
Perovskite solar cells (PSCs) that incorporate both two-dimensional (2D) and three-dimensional (3D) phases possess the potential to combine high stability of 2D PSCs with superior efficiency 3D PSCs. Here, we demonstrated in situ phase reconstruction 2D/3D perovskites using a perovskite single-crystal-assisted method. A gradient distribution RP was formed after spin-coating solution Ruddlesden–Popper (RP) single crystal, (DFP)2PbI4, onto surface, followed by thermal annealing. The resulting...
Abstract Perovskite solar cells have aroused a worldwide research upsurge in recent years due to their soaring photovoltaic performance, ease of solution processing, and low cost. The power conversion efficiency record is constantly being broken has recently reached 26.1% the lab, which comparable established technologies such as crystalline silicon, copper indium gallium selenide cadmium telluride (CdTe) cells. Currently, perovskite are standing at entrance industrialization, where huge...
We report the large-scale synthesis of silicon nanowires (SiNWs) using a simple but effective approach. High purity SiNWs uniform diameters around 15 nm were obtained by sublimating hot-pressed powder target at 1200 °C in flowing carrier gas environment. The emit stable blue light which seems unrelated to quantum confinement, related an amorphous overcoating layer oxide. Our approach can be used, principle, as general method for other one-dimensional semiconducting, or conducting nanowires.
Colloidal perovskite nanocrystals (PNCs) display bright luminescence for light-emitting diode (LED) applications; however, they require post-synthesis ligand exchange that may cause surface degradation and defect formation. In situ-formed PNCs achieve improved passivation using a straightforward synthetic approach, but their LED performance at the green wavelength is not yet comparable with of colloidal PNC devices. Here, it found limitations in stem from uncontrolled formation kinetics:...
Non-developable origami is a unique type of structures that cannot be unfolded into flat sheet without stretching. In this work, we study the kinematics and dynamics such origami, theoretically, numerically experimentally, considering rigid panels stretchable creases. Unlike developable find non-developable exhibits distinct folding angle relationships, leading to several separate branches in its kinematic configuration space with snap-through locking behaviours. By modelling creases as...
Abstract. Ozone (O3) pollution research and management in China have mainly focused on anthropogenic emissions, while the importance of natural processes is often overlooked. With increasing frequency extreme weather events, role exacerbating O3 gaining attention. In September 2022, Pearl River Delta (PRD) southern experienced an extended period (25 d) regional exceedances high temperatures (second highest over last 2 decades) due to conditions influenced by subtropical typhoon peripheries....

All-inorganic perovskite solar cells (PSCs) are attracting considerable attention due to their promising thermal stability, but inferior power-conversion efficiencies (PCE) hinder realistic application. Here, we propose an approach through surface modification based on methyl ammonium halide (MAX) for inorganic CsPbI2Br processed at a low temperature. The combined benefits of the introduced MAX modifier enable boosting power conversion efficiency 14.8% with impressive FF 82.2% in PSCs. Our...
High-entropy alloy (HEA) catalysts have recently attracted worldwide research interest due to their promising catalytic performance. Most current studies focus on designing HEA through trial-and-error methods. This produces scattered data and is not conducive obtaining a fundamental understanding of the structure-property-performance relationships for catalysts, thereby hindering rational design. High-throughput (HT) techniques machine learning (ML) methods show significant potential in...

Propensity score matching (PSM) was used balance baseline differences. A multivariate Cox regression model assess relationship mortality. The primary outcome 28-day mortality.A total of 12,360 included study, involving 3,895 who received 8,465 did not. After PSM, 3,891 pairs matched. results showed...
Rationale: Although sepsis-associated encephalopathy (SAE) is a common psychiatric complication in septic patients, the underlying mechanisms remain unclear. Here, we explored role of hippocampus (HPC) - medial prefrontal cortex (mPFC) pathway cognitive dysfunction lipopolysaccharide-induced brain injury. Methods: Lipopolysaccharide (LPS, 5 mg/kg, intraperitoneal) was used to induce an animal model SAE. We first identified neural projections from HPC mPFC via retrograde tracer and virus...

Abstract Lead‐free 2D antimony‐based halide perovskites with excellent optoelectronic properties, low toxicity, and good intrinsic stability are promising for photovoltaic devices. However, the power conversion efficiency (PCE) of perovskite solar cells (PSCs) is still lower than 3% due to poor crystallinity random orientation. Herein, it found that Cs 3 Sb 2 Cl x I 9‐x films prepared by adding methylamine chloride as an additive precursor solution can form a mixed intermediate phase 0D...
