Boosting Multicolor Emission Enhancement in Two-Dimensional Covalent-Organic Frameworks via the Pressure-Tuned π-π Stacking Mode.

Covalent-organic frameworks (COFs) are dynamic covalent porous organic materials constructed from emissive molecular organic building blocks. However, most two-dimensional (2D) COFs are nonemissive or weakly emissive in the solid state owing to the intramolecular rotation and vibration together with strong π-π interactions. Herein, we report a pressure strategy to achieve the bright multicolor emission from yellow to red in the 2D triazine triphenyl imine COF (TTI-COF).

Rational Regulation of High-Entropy Perovskite Oxides through Hole Doping for Efficient Oxygen Electrocatalysis.

Due to the high configuration entropy, unique atomic arrangement, and electronic structures, high-entropy materials are being actively pursued as bifunctional catalysts for both the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in rechargeable zinc-air batteries (ZABs). However, a relevant strategy to enhance the catalytic activity of high-entropy materials is still lacking. Herein, a hole doping strategy has been employed to enable the high-entropy perovskite La(CrMnFeCoNi)O to effectively catalyze the ORR and OER.

Therapeutic Potential of Shilong Qingxue Granule and Its Extract Against Glutamate Induced Neural Injury: Insights from In Vivo and In Vitro Models.

Ethnopharmacological Relevance: Shilong Qingxue Granule (SQG), a traditional Chinese medicine, effectively treats the secondary neurological damage and functional deficits caused by cerebral hemorrhage, though its exact mechanism remains unclear.

Aim Of The Study: This study aimed to investigate the effects of SQG and its mechanisms.

Materials And Methods: we evaluated the effects of SQG and its extracts on glutamate induced nerve damage using in vivo and in vitro models.

Associations of insulin resistance estimated by glucose disposal rate with frailty progression.

Objectives: To investigate the relationship between estimated glucose disposal rates (eGDR) and the progression of frailty, using longitudinal data.

Methods: We analyzed four waves of data from the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2018, involving 6,778 middle-aged and older adults. eGDR was calculated using a specific formula, categorizing participants into high and low eGDR groups based on the lowest quartile (8.
