In 1979, Miller and Patel showed that a solution containing two diacetylene monomers, 2,4-hexadiyne-1,6-bis(phenylurethane) (HDDPU) and 2,4-hexadiyne-1,6-bis(p-chlorophenylurethane) (HDDCPU) could be used to develop latent fingermarks on a non-porous surface. In the current work, the same mixture (HDDPU:HDDCPU=10:1, in acetone solution)

We use nonequilibrium molecular dynamics simulations to investigate the structural properties of an oriented melt of n-eicosane under steady-state planar elongational flow. The flow-induced structure was evaluated using the structure factor s(k) taken as the Fourier transform of the total

Existing encapsulated organic phase change materials (PCM) usually contain a shell material that possesses a poor heat storage capacity and so results in a lowered latent heat storage density of the encapsulated PCM compared to unencapsulated PCM. Here, we demonstrate

The analysis of cocaine base is a major part of the forensic drug chemist's workload. Simplifying quantitative methodology can assist the drug chemist. Methods currently employed for quantitation of cocaine base utilize either an internal standard or a direct comparison.
