Abstract:
... In the investigation of criminal cases involving metallic weapons such as firearms and knives, the trace metal detection test (TMDT) and the transfer detection technique are two effective and on-the-spot methods to link a suspect and a suspected metallic weapon. In general, these tests need to be conducted on suspects’ hands or done by lifting trace metals from their hands within 3 days of the cri ...

Abstract:
... Starch is the most popular plant polysaccharides, which has been widely used for the development of edible coating films because of its abundance, cost-effectiveness, and excellent film-forming abilities. Starch-based films have good optical, organoleptic and gas barrier properties, however, they have poor mechanical properties. Many attempts have been made to overcome these limitations, such as t ...

Abstract:
... European restriction limits the hexavalent chromium content to not more than 3 mg/kg in leather products. Owing to the evolution of hexavalent chromium content in leathers over time, it’s difficult to guarantee the products will be harmless for consumers. The designing of an accelerated and representative artificial ageing procedure is therefore highly desirable. This article proposes a thorough s ...
