Researchers say the fabric has promising functions, comparable to in superior electronics and high-capacity batteries. — ScienceDaily

A crew from the Tulane College Faculty of Science and Engineering has developed a brand new household of two-dimensional supplies that researchers say has promising functions, together with in superior electronics and high-capacity batteries.

Led by Michael Naguib, an assistant professor within the Division of Physics and Engineering Physics, the research has been printed within the journal Superior Supplies.

“Two-dimensional supplies are nanomaterials with thickness within the nanometer dimension (nanometer is one millionth of a millimeter) and lateral dimensions 1000’s of occasions the thickness,” Naguib mentioned. “Their flatness gives distinctive set of properties in comparison with bulk supplies.”

The title of the brand new household of 2D supplies is transition metallic carbo-chalcogenides, or TMCC. It combines the traits of two households of 2D supplies — transition metallic carbides and transition metallic dichalcogenides.

Naguib, the Ken & Ruth Arnold Early Profession Professor in Science and Engineering, mentioned the latter is a big household of supplies that has been explored extensively and located to be very promising, particularly for electrochemical vitality storage and conversion. However he mentioned one of many challenges in using them is their low electrical conductivity and stability.

However, he mentioned, transition metallic carbides are wonderful electrical conductors with way more highly effective conductivity. Merging the 2 households into one is anticipated to have nice potential for a lot of functions comparable to batteries and supercapacitors, catalysis, sensors and electronics.

“As a substitute of stacking the 2 completely different supplies like Lego constructing blocks with many problematic interfaces, right here we develop a brand new 2D materials that has the mixture of each compositions with none interface,” he mentioned.

“We used an electrochemical-assisted exfoliation course of by inserting lithium ions in-between the layers of bulk transition metals carbo-chalcogenides adopted by agitation in water,” mentioned Ahmad Majed, the primary creator of the article and a doctoral candidate in Supplies Physics and Engineering at Tulane working in Naguib’s group.

Not like different unique nanomaterials, Majed mentioned, the method of constructing these 2D TMCC nanomaterials is straightforward and scalable.

Along with Naguib and Majed, the crew consists of Jiang Wei, an affiliate professor in physics and engineering physics; Jianwei Solar, an assistant professor in physics and engineering physics; PhD candidates Kaitlyn Prenger, Manish Kothakonda and Fei Wang at Tulane; and Dr Eric N. Tseng and professor Per O.A. Persson of Linkoping College in Sweden.

This research was supported by Naguib’s Nationwide Science Basis Profession Award that he obtained lower than a 12 months in the past.
