The macro-threats of microarchitectures

,
Processor vulnerabilities are no longer limited to the microarchitecural flaws identified in recent years. They now extend to different contexts and directly affect our digital uses. Faced with these increasingly widespread threats, research in security is mobilizing and multiplying approaches to better understand and address them. Maria Mushtaq, researcher at Télécom Paris and organizer of the MICSEC Winter School, sheds light on these developments and the challenges of a field in full transformation.

Greenhouse gases: Mirega sets its sights on

, , , ,
Invisible leaks, massive emissions: measuring greenhouse gases in the field remains a challenge. Mirega, a young start-up backed by high-level optical expertise, is developing a miniature infrared sensor designed to go where other instruments cannot. This technology is designed to meet growing demands in terms of detection, mobility, and climate.

Renardo lays its cards on the table in embedded electronics

, ,
Developing an embedded electronic solution in a matter of weeks rather than years: that's the challenge taken up by Renardo, a young start-up incubated at IMT Atlantique. Born out of the industrial and educational experience of its two founders, the start-up offers a modular ecosystem combining hardware and software. The aim is to increase responsiveness and democratize electronic innovation, while meeting industry requirements.
Portrait Valérie Forest

Valérie Forest: from a desire to be useful to global recognition

, ,
Valérie Forest, a professor at Mines Saint-Étienne, was recently recognized as one of the most influential scientists in the world, according to the “Stanford/Elsevier’s Top 2% Scientists” ranking. Originally from Saint-Étienne, she conducts applied research into the biological activity of inhaled particles, while also running the school's Biomedical Engineering Major. Close up on a researcher who just wanted “to be useful”.

Liquefying hydrogen: a challenge to the last grain

,
Liquefaction is a key stage in the use of hydrogen as an energy vector. The HyGen project aims to remove the technological obstacles surrounding this process in the context of decarbonized transport. At Mines Saint-Étienne, two researchers are putting their powder expertise into designing the future cryogenic heat exchangers required for storage.
Filtration pour qualité de l'air intérieur

New wind for indoor air quality

,
A research team from IMT Atlantique has developed a new method for analyzing the microorganisms in indoor air. Unlike traditional methods, this approach facilitates representative sampling over long durations. This is good news for a concern that often takes a back seat.

From 5G to 6G: the unstoppable progress of generations

,
Through a series of articles, this I'MTech collection offers various insights to better understand the technical challenges, as well as the issues of optimization and energy efficiency, that accompany the transition from 5G to 6G. Between the explosion of the IoT, the emergence of the metaverse, and the imperative of energy efficiency, we take a look at the future of telecommunications.

5G & 6G: the antennas that shape networks

,
In a context of constantly growing needs for data transmission, 5G and 6G networks must comply with increasingly strict technical obligations in terms of flexibility, miniaturization, and energy optimization. Solutions explored by researchers include optimal management of radiation patterns and the development of concrete applications for millimeter wave frequencies. Two projects, YACARI and PIIEC ME/CT, are tackling the technical obstacles to these approaches by combining different antenna technologies.

5G connecting constellations

,
A space-based solution to connect remote regions is soon to become reality. But using low-orbiting satellites as telecommunications relay stations means certain functionalities of current terrestrial solutions have to be reinvented. Their constant movement is the reason. For the BPI 5G NTN mmWave project, Télécom Paris scientists are tackling this technical challenge, by developing new algorithms and performance models in order to assess the limitations of the system and then optimize it.

Slicing: a MUST for multisectoral communication

,
In emergency situations such as a major car crash, proper coordination between the emergency, medical and transport services is vital. Yet these different operators often use compartmentalized communication services which hinder their performance. The NF-MUST project aims to create a dynamic, shared and flexible network architecture to enable seamless communication. It relies on slicing techniques and virtualized networks to meet the demands of different sectors.
