Mechanism of CO-formation promotion by Au in plasma-catalytic oxidation of CH over Au/γ-AlO at room temperature.

The plasma-catalytic oxidation of methane (CH) is a potential reaction for controlling CH emissions at low temperatures. However, the mechanism of the CH plasma-catalytic oxidation is still unknown, which inhibits the further optimization of the oxidation process. Herein, a CH oxidation mechanism over an Au/γ-AlO catalyst was proposed based on our experimental findings.

Effects of Duodenal-Jejunal Exclusion and New Bilio-Pancreatic Diversion on Blood Glucose in Rats with Type 2 Diabetes Mellitus.

Objective: The current study aimed to investigate the effects of duodenal-jejunal bypass (DJB), new bilio-pancreatic diversion (NBPD), and duodenal-jejunal exclusion (DJE) on blood glucose in rats with type 2 diabetes mellitus (T2DM).

Methods: Male Sprague Dawley rats were fed with high glucose, high fat food, and intraperitoneally injected with streptozotocin to establish a T2DM animal model. T2DM rats were randomly assigned into 4 groups: a sham group (n = 8), DJB group (n = 9), NBPD group (n = 10), and DJE group (n = 10).

[Heavy metal pollution characteristics and ecological risk analysis for soil around Haining electroplating industrial park].

The pollution status and potential ecological risks of heavy metal in soils around Haining electroplating industrial park were studied. Hakanson index approach was used to assess the ecological hazards of heavy metals in soils. Results showed that average concentrations of six heavy metals (Cu, Ni, Pb, Zn, Cd and Cr) in the soils were lower than the secondary criteria of environmental quality standard for soils, indicating limited harmful effects on the plants and the environment in general.
