Self-Reconstruction of High Entropy Alloys for Efficient Alkaline Hydrogen Evolution.

Small

January 2025

Institute for Sustainable Energy and Resources, Key Laboratory of Shandong Provincial Universities for Functional Molecules and Materials, College of Chemistry and Chemical Engineering, Qingdao University, Qingdao, Shandong, 266071, China.

Alkaline water (HO) electrolysis is currently a commercialized green hydrogen (H) production technology, yet the unsatisfactory hydrogen evolution reaction (HER) performance severely limits its energy conversion efficiency and cost reduction. Herein, PtRuFeCoNi high entropy alloys (HEAs) is synthesized and subsequently exploited electrochemically induced structural oxidation processes to construct self-reconfigurable HEAs, as an efficient alkaline HER catalyst. The optimized self-reconstructed PtRuFeCoNi HEAs with the HEAs and cobalt rutheniate interface (HEAs-CoRuO) exhibits excellent alkaline HER performance, requiring just 11.

Background: Glaucoma, diabetic retinopathy, and age-related macular degeneration impose substantial economic burdens on healthcare systems due to their high prevalence and chronic nature. Nevertheless, comprehensive Italian data is limited. This study aims to collect Italian evidence on the economic impact of these conditions to support more effective healthcare planning.

Background: In recent decades, relapsing remitting multiple sclerosis (MS) became more treatable through new disease-modifying therapies (DMTs). Identifying safe treatments with minimal fetal risks for family planning is needed.

Methods: In this prospective cohort from the German MS and Pregnancy Registry (DMSKW), we analyzed pregnancy and neonatal outcomes in MS-patients using descriptive statistics and logistic/linear regression models to compare DMT-exposed pregnancies to DMT-unexposed pregnancies.

Purpose: Oral corticosteroids (OCS) are an effective treatment for severe uncontrolled asthma or asthma exacerbations, but frequent bursts or long-term use carry serious and sometimes irreversible adverse effects, or complications such as adrenal insufficiency upon discontinuation. Our aim was to survey people with asthma on their experiences of, and attitudes towards, using OCS.

Patients And Methods: This study was a national descriptive cross-sectional survey of people with asthma in Australia.

Background: Previous studies on the prevalence and prognosis of nutritional status in valvular heart disease (VHD) were primarily limited to aortic stenosis. The nutritional status of other types of VHDs remained an underexplored area.

Objectives: This study aimed to evaluate the prevalence of malnutrition risk in different types of VHD and investigate the association between malnutrition risk and adverse clinical events.
