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…

Invention

Vertical silicon nanowires as a universal platform for highly efficient delivery of bioactive molecules into living cells

This platform consists of an array of surface-modified vertical silicon nanowires that have been chemically grown or etched on a wafer and to which virtually any kind of bioactive species (drug, protein, nucleic acid, nanoparticles) may be attached…

Invention

Paper-supported 3D cell culture for cell and tissue-based bioassays

In this new approach, cells are cultured in 3D on a paper scaffold by adding a hydrogel precursor, as a fluid containing suspended cells, to a paper support, allowing the cell-containing fluid to distribute through the paper by capillary wicking,…

Invention

Highly conformal tungsten nitride films for use in microelectronics and semiconductors

The invention describes a method of producing a uniform, smooth and conformal coating of tungsten nitride, synthesized by atomic layer deposition (ALD). The silver-colored coating (or film) is metallic and a good electrical conductor.

Invention

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…

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…
