    Synthesis and evaluation of novel Cu-based adsorbent-containing catalysts for CO<sub>2</sub> hydrogenation to methanol and value-added products حسب Rim Ismail (18192922)

    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. …"

    Enhanced optical properties of <i>β</i>-Ga<sub>2</sub>O<sub>3</sub>-<sub><em>x</em></sub>S<sub><em>x</em></sub>S: A DFT study حسب G.B. Eshonqulov (22927297)

    منشور في 2025
    "…Here, we conduct systematic density functional theory calculations to study the effect of sulfur doping on the electronic and optical properties of <i>β</i>-Ga<sub>2</sub>O<sub>3</sub>. We find that the band gap of the material decreases with increasing sulfur content (from 4.81 eV to 1.59 eV), accompanied by symmetric shifts in both the valence-band offset and the conduction-band edge. …"

    Methylation at global LINE-1 repeats in human blood are affected by gender but not by age or natural hormone cycles حسب El Maarri, Osman

    منشور في 2011
    "…In vitro results largely confirmed these findings, as neither estrogen nor dihydrotestosterone affected LINE-1 or Alu methylation in Hek293T, HUVEC, or MDA-kb2 cell lines. …"

    In-situ grown ternary metal hydroxides@3D oriented crumpled V₂C MXene sheets for improved electrocatalytic oxygen evolution reaction حسب Iqbal, Anum

    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.…"

    Co-production of high density biomass and high-value compounds via two-stage cultivation of Chlorella vulgaris using light intensity and a combination of salt stressors حسب Eman A. El-fayoumy (17788952)

    منشور في 2023
    "…Cultivation of C. vulgaris in a medium containing 7.5 g L<sup>−1</sup> NaCl/ 7.5 g L<sup>−1</sup> CaCl<sub>2</sub> had remarkably increased the lipid content (31.15 ± 1.18%) and lipid productivity (14.55 ± 1.48 mg L<sup>−1</sup> d<sup>−1</sup>). …"
