Many scientists said it wasn’t possible, but PhD research supervised by LTM and LMGP recently proved the naysayers wrong, demonstrating that electrical current does, in fact, flow through silicon nanonets, unorganized networks of silicon nanowires. The research also looked at a reproducible process for making the nanonets and hybridizing them with strands of DNA. A […] >>

Researchers at Leti have characterized RRAM (resistive random-access memory) in operation, at the nanometric scale, using a transmission electron microscope. And the method they used can be applied to other types of memory. The researchers mapped the on/off states’ structures, compositions, and potentials on a memory whose active layer measures less than 20 nm thick. […] >>

Tissue flap surgery is a technique used in breast and maxillofacial reconstruction. A flap of tissue, which can contain bone, muscle, skin, and fat, is taken from another part of the body, and moved to a new site where the blood vessels are reattached. Because of the risk of clots and tissue death, patients are […] >>

When exposed to the sun, the human skin makes a pigment called melanin to protect itself—or so we thought! A team of researchers from around the globe (including several from INAC) recently demonstrated that, when exposed to UVA irradiation, the molecules that help synthesize melanin alter the DNA of the melanocytes (the cells that produce […] >>

Field testing of a portable pathogenic bacteria alert and identification system began a few days ago in the South of France. The system, developed by Leti and List combines lensless imaging, Raman spectrometry, and supervised classification algorithms. The system, named Bacram, was developed under the counter-bioterrorism research program of the French government’s CBRND* policy. It […] >>
