BACKGROUND Intra-abdominal infection or peritonitis is a cause for great concern due to high mortality rates. The prognosis of severe intra-abdominal infection is significantly diminished in the presence of acute kidney injury (AKI) which is often characterized by renal tubular cell death that can lead to renal failure. The purpose of the current study is to examine the therapeutic efficacy of ...

OBJECTIVES With recent advances in nanoparticle manufacturing and applications, potential exposure to nanoparticles in various settings is becoming increasing likely. No investigation has yet been performed to assess whether respiratory tract exposure to cerium oxide (CeO2) nanoparticles is associated with alterations in protein signaling, inflammation, and apoptosis in rat lungs. METHODS Spe...

A novel CeO2 nanorod/g-C3N4/N-rGO ternary composite was synthesized using a simple ultrasonic-heat treatment method for application in the photocatalytic degradation of organic pollutants under the irradiation of visible light. This material shows superior photocatalytic activity compared with pure g-C3N4 and CeO2 nanorods, and the photodegradation rate of RhB is up to 2.1-fold higher than that...

Supported platinum catalysts are used in the automotive industry for the oxidation of CO, hydrocarbons, and NOx. Dispersed Pt provides active sites for these reactions to occur. During the use of these catalyst, high temperatures will cause Pt to become volatile and sinter, forming large particles which will lead to a loss of catalytic activity. The study of Pt sintering has been of high priori...

An electrochemical sensor incorporating a signal enhancement for the determination of lead (II) ions (Pb2+) was designed on the basis of the thrombin-binding aptamer (TBA) as a molecular recognition element and ionic liquid supported cerium oxide (CeO2) nanoparticles-carbon nanotubes composite modification. The composite comprises nanoparticles CeO2, multi-wall carbon nanotubes (MWNTs) and hydr...

New information about the active sites for the water gas shift (WGS) reaction over Cu-CeO2 systems was obtained using in-situ, time-resolved X-ray diffraction (TR-XRD), X-ray absorption spectroscopy (TR-XAS, Cu K and Ce L3 edges), and infrared spectroscopy (DRIFTS). Cu-CeO2 nanoparticles prepared by a novel reversed microemulsion method (doped Ce1-xCuxO2 sample) and an impregnation method (impr...

Dissipative particle dynamics (DPD) was carried out to study the nucleation and crystal growth process of CeO2 nanoparticles in different alcohol aqueous solutions. The results showed that the nucleation and crystal growth process of CeO2 can be classified into three stages: nuclei growth, crystal stabilization and crystal aggregation except the initial induction stage, which could be reproduce...
