Transport of Multiple Enzymes through Semipermeable Membrane and Effect of Surfactants

Trigo C., Leung S.W., Bhushan A., Daniels C.K., Lai J.C.K., Idaho State University, College of Engineering, US

Surfactants are known to influence functions of many proteins in membranes, cells and tissues. Because most studies to elucidate the effects of surfactants on membrane-bound proteins and cells employed heterogeneous or complex systems, it is [...]

Mimicking Photosynthesis to Make Functional Nanostructures and Nanodevices

Shelnutt J.A., Wang Z., Song Y., Medforth C.J., Pereira E., Sandia National Laboratories, US

Photocatalytic porphyrins are used to reduce metal complexes from aqueous solution and, further, to control the deposition of metals onto porphyrin nanotubes and surfactant assembly templates to produce metal composite nanostructures and nanodevices. For example, [...]

Probing the Morphology and Tribo-Response of Nanostructured Fluid Films for Personal Care Applications

Haugstad G., Avery A., University of Minnesota, US

We present a methodology for interrogating silicone-based polymer-surfactant complex films a few nanometers in thickness. The films include 2D regions of liquid character interspersed in regions of solid character. Images are radically different in a [...]

Differential Effects of Surfactants on Enzyme Activity and Transport across a Semipermeable Cell

Utilization of SWNT-Filled Polystyrene Obtained by Miniemulsion Polymerization as a Modifier for High-Performance Epoxy Resins

Barraza H.J., Rueda O., Pompeo F., O'Rear E.A., Williams R.J.J., Resasco D.E., University of Oklahoma, US

One of the several reasons that engineering research aimed towards the purification, functionalization and incorporation of carbon nanotubes into polymeric matrices has been actively pursued for the last five years is that vastly important applications, [...]
