The charge-carrier dynamics process in well-designed hetero-nanostructural plasmonic photocatalysts is greatly improved through a multichannel sensitization effect, which therefore results significant enhancement of the efficiencies solar-to-fuels conversion.
Abstract Semiconductor quantum wells (QWs) exhibit high charge‐utilization efficiency for light‐emitting applications due to their strong charge confinement effect. Inspired by this effect, herein, work proposes a new idea significantly improve the photo‐generated separation attaining highly‐efficient solar‐to‐fuels conversion process through “semi‐reversing” conventional QWs confine only electrons. This electron confinement‐improved is implemented in well‐designed model of CdS/TiO 2 /CdS...
The interaction of atomic hydrogen and H2O with stoichiometric partially reduced CeO2(111) thin films deposited on a Cu(111) substrate was investigated by temperature programmed desorption X-ray photoelectron spectroscopy. On surface, the adsorption H(g) leads to formation surface hydroxyl (OH(a)) H2O(a) as well reduction Ce4+ into Ce3+. surfaces, stability OH(a) enhanced presence oxygen vacancies. Upon heating, hydroxyls undergo two competing reaction pathways: one is associative releasing...
The photocatalytic oxidation of methanol on a rutile TiO2(110) surface was studied by means thermal desorption spectroscopy (TDS) and X-ray photoelectron (XPS). combined TDS XPS results unambiguously identify methyl formate as the product in addition to formaldehyde. By monitoring evolution various species during TiO2(110), give direct spectroscopic evidence for formation cross-coupling chemisorbed formaldehyde with methoxy clearly demonstrate that dissociation occurs contributes methanol....

Abstract Ovarian cancer (OV) poses a significant challenge in clinical settings due to its difficulty early diagnosis and treatment resistance. FOXP4, belonging the FOXP subfamily, plays pivotal role various biological processes including cancer, cell cycle regulation, embryonic development. However, specific importance of FOXP4 OV have remained unclear. Our research showed that is highly expressed tissues, with elevated levels correlating poor prognosis. We further explored FOXP4’s function...
