Fast gelation of self-assembling peptide nanofibres triggered by electromagnetic radiation heating

Mazza M., Gaisford S., McCharty D., Uchegbu I.F., The School of Pharmacy, University of London, UK

We report a method for the preparation of peptide nanofibre gels prepared by a rapid heating/cooling cycle employing electromagnetic radiation heating. An amphiphilic peptide having a C16 chain attached via an esteric link was used [...]

Gels of Carbon Nanotubes and Nonionic Surfactant and High-quality Carbon Nanotube Films Prepared by Gel Coating

Ouyang J., National University of Singapore, SG

Processing of large-scale carbon nanotubes (CNTs) are very important for the application of CNTs in various aspects. Here, we report CNT gels by dispersing CNTs in various nonionic surfactants. High-quality CNT films were prepared by [...]

Order Development in Polymer-Clay Nanocomposites: from Aqueous Gels to Multilayered Films

Stefanescu C., Stefanescu E.A., Stefanescu C., Stefanescu E.A., Daly W.H., Negulescu I.I., Virginia Commonwealth University, US

When passing a material through a semihyperbolic convergent die in an elongational rheometer, high degrees of order are induced in the material, and the entropy changes, indicative of orientation, can be calculated. The aim of [...]

Nano-structuring of isotactic polypropylene in presence of a self-assembling nucleating agent under defined flow conditions

Balzano L., Rastogi S., Peters G., Technical University Eindhoven, NL

Presence of additives in polymers plays an important role in physical and mechanical properties. For an example DMDBS is one of the frequently used additives in polypropylenes. The additive is used to achieve higher transparency [...]
