An organization is only as good as its people – which is why the workforce of a company is often one of its largest costs. But measuring the true return on that investment can be a tricky business. It…
In recent years, the application of high-nitrogen containing azine energy materials has been one of the hot spots in the field of energy materials in China and elsewhere. This paper reviews domestic and foreign studies into high-nitrogen azine energetic materials. The synthetic methods, structural and theoretical analysis, physical and chemical properties, sensitivity properties, thermal properties and detonation properties of some typical pyrazine energetic compounds are summarised, including: 2,6-diamino-3,5-dinitropyrazine-1-oxide (LLM-105) of diazines, 4,4′,6,6′-tetra(azido)azo-1,3,5-triazine (TAAT) of triazines, 3,6-dihydrazino-1,2,4,5-tetrazine (DHT), 3,6-bis(1H-1,2,3,4-tetrazol-5-yl-amino)-1,2,4,5-tetrazine (BTATz) and 3,3′-azobis(6-amino-1,2,4,5-tetrazine) (DAAT) of tetrazine and their respective applications and potential value are described. The results of published studies reviewed here show that the application of azine energetic compounds in propellants can effectively improve the burning rate and reduce the characteristic signal; the application of azine energetic compounds in mixed explosives can reduce the sensitivity and improve the detonation performance; the application of azine energetic compounds in gas generators can reduce the combustion temperature and increase the gas content. Therefore, this class of compounds has a broad application prospect in energetic materials.

To help reduce the risks of open flame, ISO standards exist for both regular pocket lighters and the utility types that have a longer reach. In both cases, the focus is on user safety.
The publication and implementation of the China VI emission standards for diesel fuelled heavy-duty vehicles is one of the important measures to fulfil the ‘blue sky defence’ action plan in China. This paper, by interpreting the background and key technical contents of the China VI emission standards, analyses the basis of the technical requirements and their impact. Moreover, it demonstrates the main differences between the China VI and China V emission standards and the Euro VI regulations, hoping to give the relevant industry in-depth insights into the new standard.
