DREXEL HONORS FACULTY, STAFF AND STUDENT AUTHORS AND EDITORS

On February 26, 2018, the Drexel University Libraries and the Office of the Provost hosted the sixth annual Celebrating Drexel Authors Event. This year, the event honored a total of 77 Drexel authors with publications in 2017. All 5 individuals honored from the College of Engineering who were recognized for publishing Highly Cited (Web of Science) papers in 2017 were from our MSE department.  Read the full story here.

Congratulations to all of the authors!

 

Gordon Research Conference on Batteries

Drexel was represented by several current faculty members (Katya Pomerantseva, MSE, Maureen Tang, CBE, Yury Gogotsi, MSE) and alums – Prof. Gleb Yushin (Georgia Tech), Dr. Kevin Knehr (Princeton) and Prof. Kelsey Hatzell (Vanderbilt) at the Gordon Research Conference on Batteries.  Drexel faculty, students, and alumni continue making significant impact in the energy field.

 

PA Junior Academy of Science Awardees Science Fair

Three of our visiting high school students have won 1st place prizes at the PA Junior Academy of Science.  They will proceed to the State competition next in State College, PA.  The students are advised by current PhD students, Kanit Hantanasirisakul and Kathleen Maleski.

Congratulations to all!

 

Can Black Panther’s Vibranium Ever Be Real?

DNI faculty, Prof. Yury Gogotsi, is featured on website GIZMODO discussing the fictional material Vibranium, as featured in the recent popular Marvel Black Panther Movie.

Prof. Gogotsi states: “We can say that with a high probability no natural material can have those properties. As we know that all the same elements exist in the universe as on our planet earth, no mineral of pure metal is expected to have properties of Vibranium. Some of the properties of vibranium can be achieved, though not at the same scale, by design of material structure and architecture using advanced nanomaterials. Piezoelectric materials transform mechanical pressure and vibrations into voltage. Charge produced by piezoelectric materials can be stored and used. Kids running around in sneakers that lighten up with every step demonstrate this principle. Light advanced ceramic materials, such as boron carbide and silicon carbide, are used as armor in bullet-proof vests. They protect due to their extreme hardness—they are harder than any metal.

Material architectures capable of absorbing blast energy are being developed and can, potentially, protect a person jumping from a high altitude (but, again, this will be a 20-feet rather than a 20-story jump).”

Drexel COE Dean’s Highlights

Check out the Drexel College of Engineering Dean’s Highlights for a summary of the exciting research and advancements coming from Drexel.  DNI work on MXenes is featured in the innovation section of the booklet.

Joint Publication with NNFC-KAIST

Our work with KAIST on MXene sensors (S. J. Kim, H.-J. Koh, C. E. Ren, O. Kwon, K. Maleski, S.-Y. Cho, B. Anasori, C.-K. Kim, Y.-K. Choi, J. Kim, Y. Gogotsi, H.-T. Jung, Metallic Ti3C2Tx MXene gas sensors with ultrahigh signal-to-noise ratio, ACS Nano, 2018) got nice coverage in C&EN:
Congratulations to Kathleen, Babak and our KAIST-NNFC collaborators!

ACS Editors’ Choice Article on MXene Gas Sensors

Researchers from the DNI have just published a high-impact article on MXene gas sensors produced with our KAIST collaborators:
S. J. Kim, H.-J. Koh, C. E. Ren, O. Kwon, K. Maleski, S.-Y. Cho, B. Anasori, C.-K. Kim, Y.-K. Choi, J. Kim, Y. Gogotsi, H.-T. Jung, Metallic Ti3C2Tx MXene gas sensors with ultrahigh signal-to-noise ratio, ACS Nano, (2018)
It has been selected by ACS as ACS Editors’ Choice article and published Open Access ($3000 fee waived). ACS selects a  paper per day (less than 1% of all papers published) from more than 50 ACS journals as “Editors’ Choice”, so it’s an important recognition that adds visibility to our paper.
We demonstrate that a metallic 2D MXene gas-sensing channel with high conductivity greatly outperforms conventional sensing materials in two critical aspects. First, a Ti3C2Tx gas sensor exhibits a limit of detection of 50~100 parts per billion (ppb) for volatile organic compounds, which is one of the lowest limits of their detection at room temperature ever reported. Second, the extremely low noise of metallic Ti3C2Tx leads to the signal-to-noise ratio two orders of magnitude higher than that of the published sensors. This study introduces a paradigm shift from semiconducting to metallic sensing channels for developing highly sensitive sensors.
The first author, Seon Joon (Steven) Kim, is a former visiting student who spent 6 months at Drexel during his PhD study. We expect him to come back to Drexel as a visiting post-doctoral scientist supported by our NNFC-KAIST-Drexel Nano Co-op Center soon.
Congratulations to Steven, Kathleen, Evelyn, Babak and other co-authors!

New Energy Storage Technologies for Enabling Renewables at CHF

Prof. Yury Gogotsi and Prof. M. Stanley Whittingham, professor of chemistry and materials science and engineering, SUNY Binghamton presented “New Energy Storage Technologies for Enabling Renewables” at the Chemical Heritage Foundation. 
Many systems and devices we use every day, including our cell phones and laptops, require batteries. Electric cars, solar and wind farms, and off-grid homes need much larger batteries. And we expect smart clothes and the internet to change how we live and how we gather and consume information in the near future. They will all need to be powered, but by much smaller, more flexible, and longer-lasting energy storage devices. The speakers presented on the discovery of the lithium battery and the long journey from the Sony camcorder battery to the modern lithium-ion battery. They also explained what is coming after lithium-ion batteries. In particular, “batteries on steroids,” or electrochemical capacitors, that now power buses in many Chinese cities, open the doors of an Airbus 380 in an emergency, and harvest braking energy from SEPTA trains, will be discussed. Finally, future flexible, transparent, microscale, wearable, and other energy storage devices that are expected to become ubiquitous within the next decade will be discussed.
