Program Highlights

Programming molecular self-assembly of intrinsically disordered proteins
New model systems of liquid protein assemblies offer insights into naturally-occurring counterparts.

The materials genome gets hot!

The goal of this seed project is to bring first-principles theory closer to experimental reality.

Simple stretch “flips” the sign of charge carriers

Electricity is the flow of charged particles through a material, such as a wire — a process that resembles a river of water molecules flowing through a canyon. But are the charged particles positive or negative?

Down the rabbit hole: Sinking electrons in a Weyl sea
Weyl semimetals are newly discovered topological electronic materials in which surface electrons (Fermi arcs) are topologically connected with those of the bulk. Princeton researchers have found experimental evidence that electrons can transverse the bulk through the special momentum states, called Weyl points, moving between opposing surfaces.

Single photon bound states in microwave photonic crystals
Photonic crystals provide an extremely powerful toolset for manipulation of optical dispersion and density of states. Princeton researchers' recent work opens exciting prospects for engineering long-range spin models in the circuit QED architecture, and new opportunities for dissipative quantum state engineering.

Glass transition of irreversibly adsorbed nanolayers
Princeton University researchers are investigating how the Tg of an adsorbed layer is influenced by the free surface and employing a fluorescence technique to directly measure the Tg of the adsorbed layer buried in a film.

Electron spin coherence of shallow donors in germanium
An international collaboration led by Princeton University IRG3 researchers have measured electron spin coherence in germanium for the first time.

MAPLE of Polymer Films for Morphology Control
Princeton researchers found that deposition temperature can significantly affect the stability of liquid phase PEO in MAPLE (matrix assisted pulsed laser evaporation)-deposited films, which results in different crystallization kinetics.

Successful synthesis of novel MOF compositions
Successful synthesis of novel MOF compositions employing “in-house made” organic linkers.  These MOF compositions  displayed superior catalytic ability in the conversion of fatty acid methyl esters  (FAMEs) into liquid fuel hydrocarbons. Synthesis of microporous carbon membranes derived from metal organic frameworks for natural gas purification.

Surface Patterning of Nanoparticles with Polymer Patches
We demonstrate nanoparticle surface patterning, which utilizes thermodynamically driven segregation of polymer ligands from a uniform polymer brush into surface pinned micelles following a change in solvent quality.
