Enhancement of light-driven adsorption efficacy through the integration of NiCoO onto CeO for photo-ozone catalytic degradation of toluene.

In this study, a co-catalytic route was explored to enhance the photo-ozone catalytic degradation of volatile organic compounds (VOCs). NiCoO was loaded onto the surface of CeO nanoparticles to create a composite catalyst (10%NiCoO/CeO). The integration of NiCoO onto CeO enhanced the interaction between the catalyst and toluene, a representative VOC, resulting in significantly increased toluene adsorption without a corresponding increase in specific surface area.

Engineered inverse opal structured semiconductors for solar light-driven environmental catalysis.

Inverse opal (IO) macroporous semiconductor materials with unique physicochemical advantages have been widely used in solar-related environmental areas. In this minireview, we first summarize the synthetic methods of IO materials, emphasizing the two-step and three-step approaches, with the typical physicochemical properties being compared where applicable. We subsequently discuss the application of IO semiconductors (, TiO, ZnO, g-CN) in various photo-related environmental techniques, including photo- and photoelectro-catalytic organic pollutant degradation in water, optical sensors for environmental monitoring, and water disinfection.

Structural and Chemical Transformations of Zinc Oxide Ultrathin Films on Pd(111) Surfaces.

Structural and chemical transformations of ultrathin oxide films on transition metals lie at the heart of many complex phenomena in heterogeneous catalysis, such as the strong metal-support interaction (SMSI). However, there is limited atomic-scale understanding of these transformations, especially for irreducible oxides such as ZnO. Here, by combining density functional theory calculations and surface science techniques, including scanning tunneling microscopy, X-ray photoelectron spectroscopy, high-resolution electron energy loss spectroscopy, and low-energy electron diffraction, we investigated the interfacial interaction of well-defined ultrathin ZnOH films on Pd(111) under varying gas-phase conditions [ultrahigh vacuum (UHV), 5 × 10 mbar of O, and a D/O mixture] to shed light on the SMSI effect of irreducible oxides.

Localization and Stabilization of Photogenerated Electrons at TiO Nanoparticle Surface by Oxygen at Ambient Temperature.

Understanding the mechanism by which oxygen adsorption influences the separation behavior of charge carriers is important in photocatalytic removal of air pollutants. In this study, we performed steady-state surface photovoltage and surface photocurrent spectroscopy combined with an atmosphere control system to determine the effect of oxygen on the charge separation behavior at the surface of anatase TiO nanoparticles at ambient temperature. Results showed that photogenerated electrons were movable in N atmosphere but were localized in O atmosphere.

Variance of Serum Lipid Levels in Stroke Subtypes.

Background: An increasing number of epidemiological studies have identified a close relationship between dyslipidemia and atherosclerotic stroke. Indeed, lipid metabolism is significantly different among the different ischemic stroke subtypes. There are few studies available regarding risk factors for specific subtypes of ischemic stroke, and in particular, there is little evidence about the role of dyslipidemia.

Neuroprotective effect of Panax notoginseng plysaccharides against focal cerebral ischemia reperfusion injury in rats.

Our present study was conducted to investigate whether Panax notoginseng plysaccharides (PNPS) exerted a neuroprotective effect against focal cerebral ischemia/reperfusion (I/R) injury in rats. Before mice were subjected to middle cerebral artery occlusion (MCAO) for 2 h and reperfusion for 22 h, PNPS at the doses of 50, 100, and 200 mg/kg was administered once a day intragastrically for continuous 7 days. Oral administration of PNPS could significantly reduce the severity of neurological deficits, infarct volumes, cerebral edema, and neuronal death caused by MCAO in rats.
