K9 Chemistry: A Safer Way to Train Detection Dogs NIST

Splet02. dec. 2024 · PDMS absorbs odors and releases them slowly over time. Enclose it in a container with an explosive or narcotic for a few weeks until it absorbs the odors, and you can then use it to safely train dogs to detect the real thing. But a few weeks is a long time, and now, NIST researchers have developed a faster way to infuse PDMS with vapors. Splet08. mar. 2024 · The toughness of Sylgard PDMS and composite PDMS is measured in this work. The few composites have low toughness because they have low fiber/matrix modulus contrast.
