Summary:
Researchers are reporting the development of an inexpensive portable test for accurately identifying flammable liquids used in arson -- the leading cause of fires and the second leading cause of fire deaths in the United States. Identification of flammable liquids used in arson usually requires time-consuming laboratory tests. The new test, called gas chromatography-differential mobility spectrometry works fast and is small enough for use in the field, they say.

Researchers in Ohio are reporting development of an inexpensive portable test for accurately identifying flammable liquids used in arson -- the leading cause of fires and the second leading cause of fire deaths in the United States.

Identification of flammable liquids used in arson usually requires time-consuming laboratory tests, Yao Lu and Peter Harrington point out. The new test, called gas chromatography-differential mobility spectrometry (GC-DMS), works fast and is small enough for use in the field, they say.

In laboratory studies, the researchers added seven different flammable liquids to carpet samples and then ignited the samples to simulate an arson event. Analysis of the burned carpet with GC-DMS identified the individual flammable liquids with an accuracy rate of 99 percent. The results demonstrate that this novel test "could be successfully used for forensic analysis of ignitable liquids from fire debris," the report states.

Their study is scheduled for the Sept. 1 issue of ACS' Analytical Chemistry.

Porsche CEO Says Supercar Is Not Dead: Cue the Spyder 918

TheStreet (Apr. 16, 2014) The Porsche Spyder 918 proves that, in an automotive world obsessed with fuel efficiency, the supercar is not dead. Porsche North America CEO Detlev von Platen attributes the brand's consistent sales growth -- 21% in 2013 -- with an investment in new technology and expanded performance dynamics. The hybrid Spyder 918 has 887 horsepower and 944 lb-ft of torque, but it can run 18 miles on just an electric charge. The $845,000 vehicle is not a consumer-targeted vehicle but a brand statement.
