Cu/NiO nanorods for efficiently promoting the electrochemical nitrate reduction to ammonia.

The electrochemical nitrate reduction reaction (ENORR) is a green ammonia synthesis method under ambient conditions relative to the traditional Haber-Bosch technology, which does not require high-temperature or high-pressure conditions and can convert nitrate pollutants in the environment into value-added NH, thus achieving a dual purpose. However, more electrocatalysts with a remarkable performance towards high-efficiency ENORR need to be developed. In this work, a Cu/NiO-NF composite electrocatalyst with a nanorod structure on nickel foam was successfully fabricated, which contains heterogeneous interfaces between Cu and NiO toward selective electrocatalytic nitrate reduction for ammonia synthesis.

[Effect of nutritional support on immune function in patients with severe pulmonary infection after renal transplantation].

Objective: To study the effect of parenteral plus enteral nutrition (PN+EN) and total parenteral nutrition (TPN) support on the postoperative immune function in renal recipients with severe pulmonary infection.

Methods: Twenty renal recipients with severe postoperative pulmonary infection were randomly assigned into two equal groups to receive PN+EN or standard TPN, both supplied with equal nitrogen and calorie. The plasma levels of total protein, albumin, hemoglobin and peripheral blood IgA, IgG, IgM, total lymphocyte count, and CD4/CD8 ratio were measured before and after the treatment.
