Abstract. An oxalic acid-assisted hydrothermal deposition method to prepare highly dispersed W/γ -Al2O3 and NiW/γ -Al2O3 hydrodesulfurization catalysts without strengthening the metal–support interaction was developed and compared with the conventional impregnation method. The resulting oxidic and sulfided catalysts were characterized, and their catalytic performance was assessed. The r…
AuAg alloy nanoparticles (NPs) have stimulated increasing interest because of their unique optical, electronic, and catalytic properties. One feature of these NPs is the tunability of surface plasmon resonance (SPR) frequency by the composition of the alloy, from 520 nm (for Au) to 400 nm (for Ag). It has been also reported that AuAg alloy NPs show enhanced catalytic activity for CO oxidation c…
We studied a novel photoanode structure inspired by butterfly wing scales with potential application on dye-sensitized solar cell in this paper. Quasi-honeycomb like structure (QHS), shallow concavities structure (SCS), and cross-ribbing structure (CRS) were synthesized onto a fluorine-doped tin-oxide-coated glass substrate using butterfly wings as biotemplates separately. Morphologies of the…
Monolayer-FePt nanoparticles/boron carbide-matrix composite thin films on Si substrate were fabricated by a two-step method. Scanning electron microscopy indicates that the 6 nm FePt nanoparticles are well-separated in the monolayer with an average interparticle distance of
Background In response to high salt intake, transcription factor hypoxia-inducible factor (HIF) 1α activates many antihypertensive genes, such as heme oxygenase 1 (HO-1) 1 and cyclooxygenase 2 (COX-2) in the renal medulla, which is an important molecular adaptation to promote extra sodium excretion. We recently showed that high salt inhibited the expression of HIF prolyl-hydroxylase 2 (PHD2)…
