Method for Separating and Recovering Rare Earth Elements Using Bacteria

Monolithically-integrated graphene structures as sensors

Graphene is a single, atomic-layer thick two-dimensional sheet of bonded carbon atoms that is characterized by superb electric and mechanical properties, thermal conductivity, and optical transparency. Graphene is a promising candidate material for…

Electrically-driven nanoscale lasers

This invention is the first demonstration of an electrically driven nanoscale laser. A CdS nanowire, comprising a Fabry-Perot cavity, in contact with an electrode distributed along its length or crossing a Si nanowire, lases above a threshold…

Bubble expansion of homogeneous epoxy suspensions of nanowires and carbon nanotubes to produce large area films

The invention describes a general and scalable, low temperature method involving bubble expansion of homogeneous epoxy suspensions of nanowires and carbon nanotubes to produce large area films. The nanowires and carbon nanotubes are well aligned in…

Analyzing trace gases at part-per-billion levels by rapid gas-phase cooling

This invention realizes a new idea of using buffer gas to rapidly cool small gas molecules to very low temperatures.

One-dimensional hole gas in germanium/silicon nanowire heterostructures

Oxygen-activated gold as a green catalyst for selective methoxycarbonylation

A group of Harvard scientists led by Profs. Madix and Friend has developed a catalyst based on gold for very selective production of dimethyl carbonate. The new process is environmentally friendly and its advantages are threefold. First, it starts…

Control over deposition of nanoscale materials using structured surfaces

The ability to precisely localize and control deposition of materials at the nanoscale is extremely important for a wide variety of emerging technologies. Many unique physical properties emerge only at the nanoscale and it is very useful to be able…

Probing a living cell through a nanotube

The hybrid nanoscale system developed by Prof. Lieber’s team provides a unique approach for recording intracellular electrical signals. The system consists of a hollow nanotube, which serves as a probe, and a Si nanowire based field-effect…
