High-Brightness Perovskite Light-Emitting Diodes with Suppressed Efficiency Roll-off Using the Green Solvent γ-Valerolactone.

The application of promising perovskite light-emitting diodes (PeLEDs) faces a significant challenge known as efficiency roll-off, which refers to the decline in external quantum efficiency (EQE) at high current densities. This issue arises mainly from high trap densities in perovskite films and imbalanced carrier injection, which limit improvements in brightness and stability of PeLEDs. Here, we develop a green solvent strategy using γ-valerolactone (GVL) to suppress efficiency roll-off in PeLEDs.

Dysthyroid optic neuropathy treated with tocilizumab.

Summary: Dysthyroid optic neuropathy (DON) is the most serious complication associated with Graves' orbitopathy (GO). The primary treatment approach for DON is high-dose intravenous methylprednisolone infusion and decompression surgery. However, not all patients are suitable candidates for or can tolerate these two treatment options.

The Diminution of R-Loops Generated by LncRNA DSP-AS1 Inhibits DSP Gene Transcription to Impede the Re-Epithelialization During Diabetic Wound Healing.

Re-epithelialization constitutes a critical stage in the intricate process of wound healing, yet its mechanisms in the context of diabetic wounds remain elusive. In this study, the role of the mesenchymal-epithelial transition (MET) vis-à-vis the epithelial-mesenchymal transition (EMT) of keratinocytes in diabetic wound re-epithelialization is investigated. The findings reveal an impediment in the MET process, rather than EMT, which significantly compromised re-epithelialization in diabetic wounds.

Colloidally uniform single-crystal precursors enable uniform FAPbI films for efficient perovskite submodules.

With the unprecedented research development on lead halide perovskite photovoltaics, scaling up fabrication while comprehensively understanding the properties of cost-effective and highly uniform precursor films has become critical for their practical application. When enlarging the device area, good precursor purity serves as the first step in ensuring the uniformity of the perovskite film. Chemical purity and colloidal uniformity in the precursor solution both play important roles in dictating film uniformity and defect density.

Recent centennial drought on the Tibetan Plateau is outstanding within the past 3500 years.

Given growing concerns about global climate change, it is critical to understand both historical and current shifts in the hydroclimate, particularly in regions critically entwined with global circulation. The Tibetan Plateau, the Earth's largest and highest plateau, is a nexus for global atmospheric processes, significantly influencing East Asian hydroclimate dynamics through the synergy of the Asian Monsoon and the Westerlies. Yet, understanding historical and recent hydroclimate fluctuations and their wide-ranging ecological and societal consequences remains challenging due to short instrumental observations and partly ambiguous proxy reconstructions.

Acidic Engineering on Buried Interface toward Efficient Inorganic CsPbI Perovskite Light-Emitting Diodes.

Inorganic CsPbI perovskite has emerged as a promising emitter for deep-red light-emitting diodes (LEDs) due to its intrinsic thermal stability and suitable bandgap. However, uncontrollable CsPbI crystallization induced by an alkaline zinc oxide (ZnO) substrate in bulk film-based LEDs leads to insufficient external quantum efficiencies (EQEs) at high brightness, leaving obstacles in commercialization progress. Herein, we demonstrate an effective acidic engineering strategy with wide applicability to modify the surface property of ZnO and regulate CsPbI crystallization.

The trigger mechanisms and the gene regulatory pathways of organic acid secretion during the vanadium-titanium magnetite tailing bioleaching.

The long-term mining of vanadium-titanium (V-Ti) magnetite has generated a large accumulation of tailings, which can lead to metal pollution via microbial bioleaching. Current research has focused on the bioleaching of minerals, and a few studies have explored microbial responses to metals only through limited metabolite concentrations. However, the trigger mechanisms of metal release during the V-Ti magnetite tailing bioleaching and key gene regulatory pathways for organic acid metabolism are still unclear.

Chromium(VI) and nitrate removal from groundwater using biochar-assisted zero valent iron autotrophic bioreduction: Enhancing electron transfer efficiency and reducing EPS accumulation.

Current strategies primarily utilize heterotrophic or mixotrophic bioreduction for the simultaneous removal of Cr(VI) and NO from groundwater. However, given the oligotrophic nature of groundwater, autotrophic bioreduction could be more appropriate, though it remains notably underdeveloped. Here, an autotrophic bioreduction technology utilizing biochar (BC)-assisted zero valent iron (ZVI) is proposed.

SREBP1 induction mediates long-term statins therapy related myocardial lipid peroxidation and lipid deposition in TIIDM mice.

Statins therapy is efficacious in diminishing the risk of major cardiovascular events in diabetic patients. However, our research has uncovered a correlation between the prolonged administration of statins and an elevated risk of myocardial dysfunction in patients with type II diabetes mellitus (TIIDM). Here, we report the induction of sterol regulatory element-binding protein 1 (SREBP1) activation, associated lipid peroxidation, and the consequent diabetic myocardial dysfunction after statin treatment and explored the underlying mechanisms.

Impurity-healing interface engineering for efficient perovskite submodules.

An issue that affects the scaling-up development of perovskite photovoltaics is the marked efficiency drop when enlarging the device area, caused by the inhomogeneous distribution of defected sites. In the narrow band gap formamidinium lead iodide (FAPbI), the native impurities of PbI and δ-FAPbI non-perovskite could induce unfavoured non-radiative recombination, as well as inferior charge transport and extraction. Here we develop an impurity-healing interface engineering strategy to address the issue in small-area solar cells and large-scale submodules.

Therapeutic application of extracellular vesicular EGFR isoform D as a co-drug to target squamous cell cancers with tyrosine kinase inhibitors.

Targeting wild-type epidermal growth factor receptor (EGFR) using tyrosine kinase inhibitors (TKIs) never achieved its purported success in cancers such as head and neck squamous cell carcinoma, which are largely EGFR-dependent. We had previously shown that exceptional responders to TKIs have a genetic aberration that results in overexpression of an EGFR splice variant, isoform D (IsoD). IsoD lacks an integral transmembrane and kinase domain and is secreted in extracellular vesicles (EVs) in TKI-sensitive patient-derived cultures.
