Constructed Mott-Schottky Heterostructure Catalyst to Trigger Interface Disturbance and Manipulate Redox Kinetics in Li-O Battery.

Lithium-oxygen batteries (LOBs) with high energy density are a promising advanced energy storage technology. However, the slow cathodic redox kinetics during cycling causes the discharge products to fail to decompose in time, resulting in large polarization and battery failure in a short time. Therefore, a self-supporting interconnected nanosheet array network NiCoO/MnO with a Mott-Schottky heterostructure on titanium paper (TP-NCO/MO) is ingeniously designed as an efficient cathode catalyst material for LOBs.

In-situ formed Co nano-clusters as separator modifier and catalyst to regulate the film-like growth of Li and promote the cycling stability of lithium metal batteries.

Lithium metal batteries (LMBs) are considered a highly prospective next-generation energy storage technology. However, their large-scale commercial application is hampered by the uncontrollable growth of Li dendrites, which accompany the boundless inflation of the battery's volume. In this study, we address this challenge by fabricating a porous structure of the MOF-derived CoP nanocube film (CoP-NC@PP) as a adorned layer for the separator.

Epidemiology of adenovirus type 5 neutralizing antibodies in healthy people and AIDS patients in Guangzhou, southern China.

Recombinant adenovirus serotype 5 (Ad5) viruses have been extensively explored as vectors for vaccination or gene therapy. However, one major obstacle to their clinical application is the high prevalence of preexisting anti-Ad5 immunity resulting from natural infection. It has been reported that there are geographic variations in the prevalence of natural adenovirus infection.

[Epidemiological study of human type 5 adenovirus in Guangzhou using chemiluminescence for neutralizing antibody assay].

Objective: To establish a high-throughput chemiluminescence assay of serotype 5 specific neutralizing antibody and understand the epidemiology of this antibody in the healthy adults and children in Guangzhou.

Methods: Using rAd5 carrying the reporter gene of secreted alkaline phosphatases (SEAP), serum samples from 116 healthy adults and 94 healthy children were examined with chemiluminescence assay to detect the presence of Ad5 neutralizing antibody. The reliability of this assay was tested against conventional cytopathic effect observation.
