Synthesis and evaluation of novel Cu-based adsorbent-containing catalysts for CO<sub>2</sub> hydrogenation to methanol and value-added products
منشور في 2024"…<p dir="ltr">In this work, sequential incipient wetness impregnation method was used to synthesize Cu/Al<sub>2</sub>O<sub>3</sub>, Cu/Na<sub>2</sub>O/Al<sub>2</sub>O<sub>3</sub> and Cu/CaO/Al<sub>2</sub>O<sub>3</sub> catalysts in different compositions for CO<sub>2</sub> conversion to value-added products. Synthesized catalysts were characterized using various analytical techniques and their performances for CO<sub>2</sub> catalytic conversion were tested in a high-pressure packed bed reactor under reaction conditions of P = 60 bars, T = 300 °C, and H<sub>2</sub>/CO<sub>2</sub> = 3. …"

In-situ grown ternary metal hydroxides@3D oriented crumpled V₂C MXene sheets for improved electrocatalytic oxygen evolution reaction
منشور في 2024"…In essence, this study features a facile approach for the confined growth of multi transition metal hydroxides in the presence of morphologically unique 3D crumpled V₂C MXene architectures. Consequently, the increased OER reaction kinetics and improved stability of the synthesized composites are potentially due to synergistic interplay between well dispersed active sites and the conductive substrate.…"

Diagnosing type 2 diabetes using Hemoglobin A1c: a systematic review and meta-analysis of the diagnostic cutpoint based on microvascular complications
منشور في 2020"…</p><h3>Conclusions</h3><p dir="ltr">The prevalence of nephropathy and moderate retinopathy was increased in subjects with HbA1c values ≥ 6.5% confirming the high specificity of this value for diagnosing T2DM; however, at HbA1c < 6.5% retinopathy increased at age > 55 years and, most strikingly, in African-Americans, suggesting there may be excess microvascular complication prevalence (particularly nephropathy) in individuals below the diabetes diagnostic threshold.…"
