Development of γ-AlO with oxygen vacancies induced by amorphous structures for photocatalytic reduction of CO.

Inducing amorphous components into AlO leads to elongation of the Al-O bond and the formation of oxygen vacancies, which makes AlO an independent photocatalyst for CO adsorption and reduction. The generation rate of CO can reach 36.5 μmol g h, which is 6.

[Determination of trace copper and zinc in vegetable oils by derivative flame atomic absorption spectrometry combined with flow-injection technique].

A new method was proposed to determine trace copper and zinc in vegetable oils by derivative flame atomic absorption spectrometry combined with flow-injection technique. The flaw that sampling is large and matrix interference was serious in conventional Flame Atomic Absorption Spectrometry (FAAS) was overcome by flow-injection sampling technique. The sensitivity and signal selectivity were enhanced when derivative technique was used in flame atomic absorption spectrometry.

[Inoculation of bacille calmette guerin combined with intraperitoneal adenosine injection enhances antibacterial effect of macrophage against Mycobacterium tuberculosis in mice].

Objective: The protection rate of inoculation with BCG vaccine is only 50 percent, and most of patients with tuberculosis had a history of BCG vaccine inoculation. Adenosine (ADO) has an immunomodulating effect; it promotes immune reaction by increasing number of macrophage and enhancing phagocytosis. The present study was designed to investigate if combined use of adenosine with BCG enhances the anti-Mycobacterium tuberculosis effect of macrophage in mice.
