Our cover just got out in ACS Sensors. It shows UV LEDs enhancing performances of graphene-based gas sensors by changing the electrical interactions between graphene and three chemicals tested in our experiments. CRPuO uOttawa Science #MyACSCover pubs.acs.org/pb-assets/imag…

In this work, led by Jaewoo and involving an amazing team of undergrads, we wanted to see how far we can take graphene-based sensing technology and push it towards real-life applications. At the end we were flying gas sensors on a drone! mdpi.com/1424-8220/22/6…

Ilhem’s first paper since joining the group! In collaboration with Nabila Bitri, we fabricate, characterize and deposit thin films of rGO, setting up the stage for experiments taking advantage of large size samples. #photonics uOttawa | Innovation CRPuO doi.org/10.1021/acsome…

It was nice to discuss the key role of international scientific collaboration for the development of photonics applications with Science Counsellors of the German Embassy Dr. Klaus Shindel and Silja Fischer.

GaP is a material used in photonic devices since 60 years. Shockingly, we couldn’t find a scalable fabrication technique to get <1 µm features. Mohammad’s recipe works great and is now published! mdpi.com/1624346 #photonics #nanofab Terahertz Science uOttawa | Innovation CRPuO

It is an absolute honour to be awarded the Senior Fellowship of the University of Bayreuth Centre of International Excellence “Alexander von Humboldt”. I’m looking forward to working with Profs. Lippitz and Herink on the fundamentals and applications of quantum terahertz systems.

I’m super happy to receive the ERA! It’s a great honor that I share with my collaborators and whole research group!

I’m officially starting today to “hold” my Visiting Chair of Instrumentation at TU Dortmund. I’m looking forward to many interactions during the next 6 months to explore new scientific ideas and establish new collaborations! 😊 physik.tu-dortmund.de/veranstaltungs…

Congrats Ahmed!

Using polymer, some tape (yes tape!) and a bit of metal, we fabricate a metamaterial for high-performance THz spectral filtering. This work, in collaboration with @BoydNLOLAb and Iridian, was published today in Photonics Research Optica Publishing Group opg.optica.org/prj/fulltext.c…

No time to waste? Use our rapid single-pulse THz system to monitor low-energy resonances in real time with a 20 µs resolution. Check out our Nature Comm: rdcu.be/dbr6O. Great collaboration with Angela Gamouras and Nicolas Joly. JCEP uOttawa Science uOttawa | Innovation

I’m looking for someone able to make a new website for my research group. Can you recommend anyone?

We show that scientific breakthroughs can be used to lower costs & increase practicality of lab equipment. The collaboration with OZ Optics Limited & NRC Canada removes hurdles to a large-scale deployment of THz technology. doi.org/10.1364/AO.486… JCEP uOttawa Science uOttawa | Innovation

Nice to read about Mohammad’s postdoctoral research in the Ultrafast THz lab (👨‍🔬💻🔧🔬🧹) and how it led him to pursue a career in high-tech industry at Agilent (💰). I really like this section of the Faculty’s annual report. 😀 uottawa.ca/faculty-scienc…

Our work published in Nature Comm was featured by uOttawa media. Read it to know more about the type of projects in our lab without diving into complicated physics.🤓😎There’s also a French version! uottawa.ca/about-us/media…

An interesting discovery that changed my view on the history of science and technological development bbc.com/reel/video/p09… via BBC Reel

We efficiently trap light inside sugar to change its properties. Does this hybrid state have a better taste than good-old sugar? Not sure... but it will certainly have many applications in polaritonic chemistry! rdcu.be/dIWBs Iridian uOttawa Science

Two students in our group received their PhD at the convocation last weekend. They both built the Ultrafast THz lab from the ground up. Congratulations Dr. Wei Cui and Dr. Nicolas Couture! Furthermore, Nicolas received the 2023 Governor General’s Gold Medal for his thesis! 😆🥳
