Detection of accelerant products in motor vehicle arson : background study and interpretation of positive results
The significance of the presence of petrol in motor vehicle fires has been challenged due to the possibility of a natural occurrence of petrol residues inside the vehicle. This study was undertaken to investigate the background levels of petrol on carpet in motor vehicles, and the potential …

A rotating ring-disk study of interactions among SPS, cuprous ions, and oxygen
… and bis-(3-sulfopropyl)-disulfide (SPS), an accelerant. The copper in acid plating baths is provided by a Cu (II) salt. Cu (I) may be present as well and it influenced the effectiveness of SPS. In this investigation, the interactions among SPS, Cu (I) and oxygen were studied by rotating …

Mechanism of SPS acceleration in a PEG containing copper plating bath
… organic compounds, which act as suppressors and accelerants to copper electroplating solutions. The focus of this study is on the acceleration effect of bis-(3-sodiumsulfopropyl) disulfide (SPS) which is believed to go through an electrochemical reaction to form sodium …
