Miniature-antenna quality gets a boost

Today’s mobile devices boast increasingly-miniaturized antennas. But tiny antennas are plagued by losses—detrimental to performance. In an effort to solve the problem, researchers from Leti and IETR recently devoted two Ph.D. dissertations to lanthanum titanate, a new perovskite oxide known for...

A high-spin polymer gets synthesized

Researchers from INAC and the Warsaw University of Technology have synthesized a polymer that spins when immersed in a solution. The material, made from a polyaniline-derived polymer, is stable at ambient temperature.

The spin remains moderate (S=2), but marks a first for...

Air pollution: small doses most harmful to DNA

Toxicology studies often look at the effects of exposure to high doses of pollutants. However, are the effects underestimated for smaller doses? INAC recently examined how polycyclic aromatic hydrocarbons (PAHs)—present in emissions from motor vehicles and heating systems—damage DNA.

The researchers...

Quantum simulation sheds new light on physics of advanced transistors

Researchers at INAC and Leti recently developed a quantum simulation code that is providing groundbreaking insights into the physics of advanced FD-SOI and Tri-gate transistors.
What makes the researchers’ work so significant is that semi-traditional simulation models do not factor in the quantum effects that play an increasing role as transistor sizes trend towards the 10-nm mark. For example, as electron confinement increases, the number of bands of energy available to carry electricity decreases.
To address this challenge, INAC, Leti, and STMicroelectronics partnered up under a French National Research Agency project titled Quasanova to develop TB_Sim, a quantum simulation code suitable...

Interview: Feriel Mélaine - Ph.D. candidate, Nanobioscience, INAC-SPrAM,

Feriel Mélaine – Ph.D. candidate, Nanobioscience, INAC-SPrAM
Editor of student newspaper Chercheurs d’horizons for the 2012–2013 school year

Ph.D. students produce their own newspaper


Your student newspaper Chercheurs d’horizons is written entirely by Grenoble University Ph.D. students. Can you tell us more about it?
The newspaper was launched in 2010–2011 following a workshop given under the school’s Professional Training & Job Support Program for Ph.D. students. I worked on it in 2012–2013 with three other Ph.D. students. We did everything ourselves: writing, editing, translation, photography, and page layout. We published the third issue in September 2013, with a print circulation of 500 plus...
