Students explore the fundamental chemical concepts of vapor pressure and flash point in a real-world technical context, while gaining insight into the contemporary societal issue of biofuels. Lab activities were developed using a closed-cup instrumen

Nanoscale science and engineering (NSE) and nanotechnology are emerging fields that have captured the attention of scientists and engineers, as well as mainstream media. However, the general public is relatively unaware of NSE, and schools (both K−

We report use of thin films of the nematic liquid crystal E7 supported on chemically functionalized surfaces to indicate the presence of vapors of the organophosphorous nerve agents sarin (GB), soman (GD), tabun (GA) and VX. The surfaces were prepare

We describe the formation of self-assembled monolayers (SAMs) on gold by helical β-peptides and show that β-peptide sequence can determine whether or not the SAM displays internal order. β-Peptide sequence isomers were designed either to be global

We report the assembly of polyelectrolyte multilayer (PEM) films at the interfaces of thermotropic liquid crystal (LC) droplets dispersed in an aqueous phase. Exposure of PEM-coated droplets to surfactant slowed the bipolar-to-radial ordering transit

Smectic liquid crystals form stable, micrometer-thick films when deposited onto the surfaces of solids. In this paper, we report that orientational transitions of thin films of the smectic liquid crystal (LC), 4′-octyl-4-biphenyl-carbonitrile (8CB)

This paper reports an investigation of the influence of interfacial hydrogen bonding on the orientations of liquid crystals at surfaces. The orientations of 10 liquid crystals were examined on carboxylic acid- or methyl-terminated self-assembled mono

We report the use of Fourier transform polarization modulation infrared reflection-absorption spectroscopy (PM-IRRAS) to characterize the influence of dimethyl methylphosphonate (DMMP) on the molecular interactions occurring within thin films of nitr
