Breaking the symmetry of micro- and nanoobjects by bipolar electrochemistry

Roche J., Loget G., Fattah Z., Zigah D., Bouffier L., Kuhn A., Université de Bordeaux, ISM, UMR 5255, FR

Referring to the roman god Janus, depicted with two heads, Janus particles are defined as micro- or nano- particles owning two sides of different chemistry. They can be used as key-components in applications such as [...]

Fabrications of Bifunctional Janus and Triblock Saturn Colloids

Lin C.C., Ho C.-C., Chang C-C, Kuo C., National Cheng Kung University, TW

A synthetic approach for the fabrications of Janus and Saturn colloids was demonstrated by the sequential embedment and surface modification of silica colloids. Electrospinning of poly(methyl methacrylate) (PMMA) and poly(4-vinyl pyridine) (P4VP) blends produced polymer [...]

Dissymetric metal deposition on carbon nanotubes

Warakulwit C., Delville M.-H., Ravaine V., Limtrakul J., Kuhn A., University of Bordeaux, FR

Short carbon nanotubes have been modified selectively on one end with metal using an original bulk technique based on bipolar electrochemistry. A stabilized suspension of nanotubes is introduced in a capillary containing an aqueous metal [...]
