Insight into the Growth of Anisotropic CdSe Nanocrystals: Attachment of Intrinsically Different Building Blocks

Martinus Gijs, Virendra Kumar Parashar, Xiaopeng Huang

An in-depth understanding of the growth mechanism of nanocrystals (NCs) is of great significance for shape control of colloidal semiconductor nanostructures. In this study, we elucidate the formation mechanism of anisotropic CdSe NCs by systematically inve ...

Increased electromechanical sensitivity of polysiloxane elastomers by chemical modification with thioacetic groups

Yee Song Ko

Chemically cross-linked polydimethylsiloxane (PDMS) elastomers have gained importance as a dielectric in elastic capacitor actuators, which elongate when electrically charged. Common PDMS elastomers have a dielectric permittivity of only about 3 and thus e ...

The persistence length of adsorbed dendronized polymers

Giovanni Dietler, Michal Borkovec, Plinio Maroni, Andrey Mikhaylov

The persistence length of cationic dendronized polymers adsorbed onto oppositely charged substrates was studied by atomic force microscopy (AFM) and quantitative image analysis. One can find that a decrease in the ionic strength leads to an increase of the ...
