Success at MS&T 2017

Success at MS&T 2017

At the MS&T Conference in Pittsburgh, PA, our group enjoyed many successes. Babak, Saleesha, and Pavel won the 1st place in the Ceramographic Competition for their MXene Lion image.  Babak also delivered an excellent invited talk on “2D Metal Carbides and Nitrides (MXenes) for Green Technologies.” Finally, undergraduate researcher Nick Trainor received the Lewis C. Hoffman Scholarship from the Electronics Division of ACerS.

 

Kristy Selected for Drexel’s 40 Under 40

Kristy Jost (PhD, 2015, at 3M now) has been selected for a very prestigious  annual “40 Under 40” award. She will be featured along with other outstanding alumni  in Drexel Magazine, the magazine of Drexel University’s 150,000 alumni. Now in its sixth year, the “40 Under 40” program has recognized many outstanding young alumni who are making a mark in their professions and community.

Honorees will be presented in the winter/spring 2018 edition of Drexel Magazine and invited to a special reception during Alumni Weekend. Last year’s “40 Under 40” included entrepreneurs, activists and artists. Davide Mattia and Michael Naguib are the most recent recipients of this award. Great to see the tradition continuing. Our alumni achieve a lot of success after graduation!

Congratulations to Kristy on her selection!

Nanodiamonds May Make Lithium Batteries Safer

In the A.J. Drexel Nanomaterials Institute, diamonds are not just for jewelry and drill bits.

According to Drexel University professor Yury Gogotsi and his team of researchers, diamonds — nanodiamonds, specifically — might just be the key to making certain types of batteries more energy efficient.

When a person thinks of rechargeable batteries, they are likely picturing lithium ion batteries, which power most portable devices such as cell phones and laptops. They generate energy by transferring ions of a lightweight metal called lithium back and forth between the two ends, or electrodes, of the battery. One of these electrodes is made of a carbon-based compound called graphite, which serves as a host for the lithium. Read the full article here.

2017 Energy Storage Materials Award

Professor Yury Gogotsi has won the 2017 Energy Storage Materials Award, which is awarded by the journal Energy Storage Materials. The Award will be presented to Professor Gogotsi at the ICEnSM 2017 (2017 International Conference on Energy Storage Materials), which will be held in Shenzhen, China, on Nov. 18-21, 2017. The award, which is sponsored by Elsevier, gives special recognition to a person who has accomplished outstanding achievements in energy storage materials and devices.

Just Squeeze In — Drexel Researchers Discover When Spaces Are Tight, Nature Loosens Its Laws

It turns out that when they’re in a hurry and space is limited, ions, like people, will find a way to cram in — even if that means defying nature’s norms. Recently published research from an international team of scientists, including Drexel University’s Yury Gogotsi, PhD, shows that the charged particles will actually forgo their “opposites attract” behavior, called Coulombic ordering, when confined in the tiny pores of a nanomaterial. This discovery could be a pivotal development for energy storage, water treatment and alternative energy production technologies, which all involve ions packing into nanoporous materials.

In their paper, which was recently published in the journal Nature Materials, the researchers explain how Coulombic ordering in liquid salts starts to break down when ions are confined in small spaces — specifically carbon pores less than a nanometer in diameter. And the narrower the pore, the less the ions adhere to Coulombic ordering. Read the full press release here.

Recipe for Safer Batteries — Just Add Diamonds

Recipe for Safer Batteries — Just Add Diamonds

While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due to short-circuiting in mobile devices. In hopes of preventing more of these hazardous malfunctions researchers at Drexel University have developed a recipe that can turn electrolyte solution — a key component of most batteries — into a safeguard against the chemical process that leads to battery-related disasters.

Read the full article here.

Drexel researchers have reported that adding nanodiamonds to the electrolyte solution in lithium batteries can prevent the formation of dendrites, the tendril-like deposits of ions that can grow inside a battery over time and cause hazardous malfunctions.
