Near-infrared (NIR) detectors, serving as critical technological nodes bridging microscopic molecular recognition and macroscopic intelligent perception, meet the demands of cutting-edge technologies such as multispectral imaging. Organic semiconductor materials demonstrate unique advantages for NIR organic photodetectors (OPDs) due to their precisely tunable bandgaps, solution processability, flexibility compatibility, and biocompatibility. However, the narrow-bandgap intrinsic characteristics required for NIR response inevitably lead to carrier concentration surge that exponentially increases dark current, while hot carriers undergo phonon scattering relaxation that suppresses carrier collection.

However, it is still challenging to achieve efficient thick film devices, in particular for all-polymer OSCs, which are generally considered the most stable type of OSCs. In this study, a simple yet effective method is introduced by using a direct current (DC) field to manipulate the morphology of bulk heterojunction (BHJ) films within all-polymer OSCs during a blade coating process.

Here, we characterize a two-component DRT9 system, composed of a reverse transcriptase (RT) and a non-coding RNA (ncRNA), which exhibits a protein-primed DNA synthesis activity upon phage infection. We also determine its cryo-electron microscopy (cryo-EM) structures in different functional states.

We report the case of a 30-year-old female diagnosed with papillary thyroid carcinoma who underwent left thyroid lobectomy, isthmectomy, and comprehensive left cervical lymph node dissection. On the first postoperative day, the patient developed left-sided ptosis, a constricted pupil, blurred vision, and conjunctival congestion, leading to a clinical diagnosis of Horner syndrome.

By subjecting the plants to drought conditions and applying exogenous melatonin, we found that melatonin significantly improves the drought tolerance of fodder soybean. Remarkably, both stomatal examination and hormone analysis point to a substantial reduction in the endogenous ABA levels following melatonin treatment.

To achieve this, fibrous air filters have been widely used to remove PM but is often associated with high energy consumption as particles quickly clog the windward pores. This increases airflow resistance and requires frequent replacements that underutilizes filter materials.

pH and temperature in the gastrointestinal (GI) tract are correlated with many diseases, but patients suffer from the pain of traditional testing methods. Functionalized capsule robots for GI tract sensing offer a potential approach for early GI disease diagnosis. However, most capsule robots struggle with control and sensing integration.

Studies have shown that it is mainly expressed in the outer membrane fibroblasts of injured arteries and in the neointimal smooth muscle cells, where it promotes cell migration and tissue damage repair. However, the regulatory role of CTHRC1 as a tumor microenvironment factor in pancreatic cancer is not well understood.

Neuroinflammation, characterized by an imbalance in microglial polarization, significantly contributes to various neurological conditions, including brain injuries, and represents a key therapeutic target for these conditions. This study aimed to determine whether J147, a known neuroprotective compound, could avert neuroinflammation by influencing microglial responses via CAMKK2/AMPK signaling. Employing an LPS-induced neuroinflammation model, we demonstrate that J147 exhibits strong anti-inflammatory effects in vivo, protecting brain structure and rebalancing cytokine profiles (e.

Given the substantial negative impact of ecological river disconnection on river ecosystems and the importance of groundwater and soil moisture for the ecology of seasonal rivers in arid and semi-arid regions, developing a comprehensive index for accurately identifying ecological river disconnection in these rivers is crucial. This study introduces a new Standardized Seasonal River Disconnection Index (SSRDI), which is based on a Standardized Index (SCI) and a three-variable Copula function.

To address global challenges in sustainable energy and water treatment, metamaterials have emerged as a transformative class of materials for solar-driven photocatalysis. Through nanoscale engineering, these artificially structured materials enable precise manipulation of light-matter interactions and significantly enhance solar energy utilization beyond the limits of conventional photocatalysts. This review systematically summarizes recent progress in applying metamaterials to solar-driven processes for energy conversion and water treatment, including photocatalytic CO reduction, water splitting for hydrogen generation, degradation of organic pollutants, and solar-driven water evaporation for purification.

Herein, we show that the electron transport connectivity is a key factor determining the electron transport and device stability of OSCs. When compared to small molecular acceptors (SMAs), the larger-size polymeric acceptors (PAs) are likely to establish an electron transport network with superior connectivity.
