Program Highlights for year 2014

Glycodendrimers

Research

Dendrimers are highly branched molecules. Amphiphilic glycodendrimers have been synthesized for the first time. These macro-molecules have tunable carbohydrate head groups and hydrophobic tails. The precise architecture of the dendrimers facilitates assembly of precise structures, including vesicles (glycodendrimersomes).

Intramolecular Exciton Transport in Conjugated Polymers

Research

Using a series of acceptor-polymer-acceptor triads, IRG-2 investigators have measured intramolecular exciton diffusion in poly-3(hexylthiophene) (P3HT) for the first time.

Magnetic Charge Crystallization in Artificial Spin Ice

Research

“Artificial spin ice” is a term used for arrays of nanoscale magnetic islands on lattices that geometrically frustrate inter-island interactions.

Ligand-free Colloids and Surface Doping of Silicon Nanocrystals

Research

Inks of inorganic nanocrystals hold great promise for printed electronics but the widely used organic surfactants (ligands) needed to stabilize these inks degrade the electrical quality of the printed films.

Kondo Physics at Ferromagnet/Normal Metal Interfaces

Research

The idealized picture of an interface between two elemental materials is simply an abrupt transition between planes containing two different types of atoms.
