TEM characterizesresistive RAM in action
- News
- Research
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. […] >>

Medical imaging for safer flap reconstruction surgery
- News
- Research
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 […] >>

The sun and cancer: is melanin friend or foe?
- News
- Research
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 […] >>

- Research
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 […] >>

- News
- Research
Researchers at Leti recently created a photonic coupler with one waveguide made from III–V materials and another from silicon. The achievement marks an advance toward fast, accurate, low-cost multigas sensors. A complete gas testing system including waveguides would be capable of taking measurements at the liter scale, rather than at the cubic meter scale required […] >>
