Room Temperature Synthesis of Gradient-Distributed Ni/Fe Sites in Layered Double Hydroxides for Enhanced Oxygen Evolution Reaction.

NiFe-based materials, especially NiFe layered double hydroxides (LDHs), are recognized as the most promising non-precious metal electrocatalysts for alkaline oxygen evolution reaction (OER). However, the precisely designed distribution of active sites for enhancing activities is still significantly restricted due to the lack of reasonable modulation strategies. Herein, sulfur doped Ni/Fe gradient-distributed LDH (GD-NiFe LDH/S) is fabricated by facile air-induced strategy at room temperature.

Changes in flavor quality of raw Liupao tea during the piling process.

Purpose: Piling is a critical process for the formation of raw Liupao tea (RLT) flavor quality. However, given the unclear changes in the flavor quality of RLT during the piling process, and the key substances of taste-contributing and aroma components that affecting the flavor quality of RLT was lacking. Herein, the present study aimed at evaluating the changes in flavor quality and its key substances of RLT during the piling process.

Hypertension awareness, treatment, control, and prognosis: insights from the sub-cohort of China PEACE million persons project.

It is unclear whether and to what extent hypertension (HTN) awareness, treatment, and control affect prognosis in real-world settings. This study utilized data from the sub-cohort of the China Patient-Centered Evaluative Assessment of Cardiac Events Million Persons Project. A total of 102,358 adults aged 35-75 years were enrolled from Guangdong Province between January 2016 and December 2020.

Enhanced sludge solid-liquid separation based on Fe/periodate conditioning coupled with polyoxometalates: Cell destruction and protein adsorption.

Dewatering of waste activated sludge is a necessary step for achieving subsequent reduction, stabilization, and resource utilization. In this study, Fe/periodate (PI) coupled with polyoxometalates (POMs) conditioning was tested for realizing sludge deep dewatering. After the addition of POMs (0.

Cardiovascular Benefits and Safety Profile of Macrolide Maintenance Therapy in Patients with Bronchiectasis.

Background: Macrolide maintenance therapy (MMT) has demonstrated notable efficacy in reducing exacerbation in patients with bronchiectasis, which is a major risk factor for cardiovascular events. However, a comprehensive assessment of the cardiovascular benefits and safety profile of MMT in this population is lacking.

Methods: This territory-wide cohort study analyzed patients diagnosed with bronchiectasis in Hong Kong between 2001 and 2018.
