A mesityl-functionalized double-boron-nitrogen-oxygen-embedded multi-resonance framework achieves anti-quenching narrowband deep-blue electroluminescence with EQE over 30% and CIE of 0.046.

Developing highly efficient deep-blue multi-resonance thermal activated delayed fluorescence (MR-TADF) materials for ultra-high-definition organic light-emitting diodes (OLEDs) displays that meet the stringent BT.2020 standard remains a significant challenge. In this study, we present a strategy to achieve high-performance deep-blue MR-TADF emitters by integrating a large π-conjugated double-boron-embedded MR skeleton with strategically positioned peripheral steric hindrance groups.

A Zn-doped SbTe flexible thin film with decoupled Seebeck coefficient and electrical conductivity band engineering.

SbTe-based flexible thin films can be utilized in the fabrication of self-powered wearable devices due to their huge potential in thermoelectric performance. Although doping can significantly enhance the power factor value, the process of identifying suitable dopants is typically accompanied by numerous repeating experiments. Herein, we introduce Zn doping into thermally diffused p-type SbTe flexible thin films with a candidate dopant validated using the first-principles calculations.

Fiber ring laser biosensor based on no-core fibers for label-free DNA biomolecule measurements.

An erbium-doped fiber ring laser based on a single-mode fiber-no-core fiber-single-mode fiber (SMF-NCF-SMF) structure was constructed and experimentally demonstrated for label-free DNA hybridization measurement.

The proposed fiber ring laser sensor exhibits a high optical signal-to-noise ratio (SNR, >50 dB) and narrow full width at half maximum (FWHM, <0.

Association of physical activity during pregnancy with labor and delivery in nulliparous patients.

Background: Physical activity during pregnancy is a positive behavior for improving pregnancy outcomes, yet the relationship between physical activity during pregnancy and labor is still debated.

Objective: This study aimed to test our hypothesis that a higher level of physical activity during pregnancy is associated with a shorter labor duration.

Study Design: This was a prospective cohort study of pregnant women with singleton pregnancies and no contraindications to physical activity during pregnancy.

Predictive value of peripheral blood indicators plus procalcitonin clearance rate for mortality in cancer patients with sepsis.

This study investigated the predictive value of combining peripheral blood indicators with procalcitonin clearance rate (PCTc) to assess mortality risk in cancer patients with sepsis, aiming to develop a more sensitive and specific clinical tool. A retrospective analysis was conducted on 393 cancer patients with sepsis admitted to South China Hospital of Shenzhen University from January 2019 to January 2024. Collected data included clinical demographics, laboratory indicators such as white blood cell count, neutrophil count (NEUT), platelet count (PLT), lymphocyte count (LYC), C-reactive protein, procalcitonin (PCT), alanine aminotransferase, and the ratio of arterial oxygen partial pressure to inspired oxygen fraction, as well as functional scores like Acute Physiology and Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment.

Performance enhancement of InSnZnO thin-film transistors by modifying the dielectric-semiconductor interface with colloidal quantum dots.

Thin film transistors (TFTs) with InSnZnO (ITZO) and AlO as the semiconductor and dielectric layers, respectively, were investigated, aiming to elevate the device performance. Chemically synthesized CuInS/ZnS core/shell colloidal quantum dots (QDs) were used to passivate the semiconductor/dielectric interface. Compared with the pristine device, the device with the integrated QDs demonstrates remarkably improved electrical performance, including a higher electron mobility and a lower leakage current.

Cross-species comparative single-cell transcriptomics highlights the molecular evolution and genetic basis of male infertility.

In male animals, spermatogonia in testes differentiate into sperm, one of the most diverse cell types across species. Despite the evolutionary retention of key genes essential for spermatogenesis, the extent of their conservation remains unclear. To explore the genetic basis of spermatogenesis under strong selective pressure, we compare single-cell RNA sequencing (scRNA-seq) datasets from the testes of humans, mice, and fruit flies.

Ag(i) emitters with ultrafast spin-flip dynamics for high-efficiency electroluminescence.

Carbene-metal-amide (CMA) complexes are appealing emitters for organic light-emitting diodes (OLEDs). However, little is known about silver(i)-CMA complexes, particularly electroluminescent ones.

Dual back interface engineering optimized charge carrier dynamics in Sb(S,Se) photocathodes for efficient solar hydrogen production.

Antimony sulfoselenide (Sb(S,Se)) is a promising sunlight absorber material for solar energy conversion in photovoltaic (PV) cells and photoelectrochemical (PEC) photoelectrodes due to its excellent photoelectric properties. However, the obtained thin-film and back contact properties significantly influence the PEC performance of photocathodes, causing severe bulk recombination, carrier transport loss, and deteriorating half-cell solar-to-hydrogen (HC-STH) efficiency. This study introduces an intriguing dual back interface engineering strategy for Sb(S,Se) photocathodes by incorporating an intermediate MoO layer and a secondary carrier transport channel of Au to strengthen charge carrier dynamics.

In Situ Synthesis of Nitrogen-Doped Carbon Coated Copper: Boosting Superhydrophobicity, Conductivity, and Oxidation Resistance.

Copper (Cu), known for its excellent electrical and thermal conductivity, faces significant challenges due to its susceptibility to oxidation, which leads to the formation of nonconductive oxide layers that impair its performance. We present an in situ thermal reduction method to synthesize nitrogen-doped carbon coated copper (NC@Cu) with enhanced oxidation and corrosion resistance. Using a stable, nontoxic, and cost-effective dopamine derivative, catechol (CA), and phenylenediamine, we developed a polydopamine-like (PDL) coating on copper oxide (CuO).

Trans, trans-2,4-decadienal, a lipid peroxidation product, aggravates insulin resistance in obese mice by promoting adipose inflammation.

Peroxidation of polyunsaturated fatty acids results in the creation of numerous α, β-unsaturated aldehydes, many of which are complicated by the development of diabetes. Trans, trans-2,4-decadienal (DDE) is a dietary α, β-unsaturated aldehyde that is commonly found in food and the environment. However, it is unknown whether DDE exposure has some negative effects on glucose homeostasis and insulin sensitivity.

Mapping Biodiversity Conservation Priorities for Protected Areas for Spatial Optimization: A Case Study in the Songnen Plain, China.

The decline in biodiversity poses a serious threat to natural ecosystems and has become one of the most pressing global environmental issues. Establishing conservation priorities for protected areas (PAs) is one of the most direct and effective biodiversity conservation measures. However, conservation gaps arise as a result of existing problems in spatial layout of PAs, including overlapping protection scopes, artificial fragmentation of natural ecological regions, as well as "over-protection" and "over-exploitation.
