Improved metal complex chemical precursors for atomic layer deposition (ALD) and chemical vapor depostion (CVD) using bicyclic guanidines

A new class of metal complex precursors has been identified for use in atomic layer deposition (ALD) and chemical vapor deposition (CVD), using bicycle guanidines as ligands as opposed to acetamidines. The ALD process involves the alternating…

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,…

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…
