Professor Yuru Gogotsi received Kavli Award from MRS presidentThe Materials Research Society is playing a major role in bringing the education, research and industrial communities together at the 2014 MRS Spring Meeting.

Each year, the MRS Spring Meeting highlights groundbreaking innovations, explorations and discoveries in materials science. That year it kept this tradition by offering an exciting mix of well-established, popular topics and leading-edge research.

Symposium organizers from around the globe created a program of 57 technical symposia to capture the extraordinary progress in materials science and technology: energy, soft and biomaterials, electronics and photonics, nanomaterials, and theory and characterization.

 Yury Gogotsi presenting his Kavli Lecture at Spring MRS in San Francisco, 2014First day of the  2014 MRS Spring Meeting closes with the Fred Kavli Distinguished Lectureship in Nanoscience, where prof.Yury Gogotsi, Drexel University,  gave his talk, "Not Just Graphene—The Wonderful World of Carbon (and Related) Nanomaterials".

The Kavli Foundation supports scientific research, honors scientific achievement and promotes public understanding of scientists and their work. Its particular focuses are astrophysics, nanoscience and neuroscience.

Drexel Nanomaterials Griup director Dr. Yury Gogotsi was selected to give the Fred Kavli Distinguished Lectureship in Nanoscience at the 2014 Spring MRS meeting.

 MRS TV featured an interview with Dr. Gogotsi about his talk, titled “Not Just Graphene — the Wonderful World of Carbon.”

Not Just Graphene—The Wonderful World of Carbon (and Related) Nanomaterials

Abstract

Carbon, with its variety of allotropes and forms, is the most versatile material and virtually any combination of mechanical, optical, electrical or chemical properties can be achieved by controlling its structure and surface chemistry. While graphite, carbon fibers, glassy carbon, activated carbons, carbon black and diamond are widely used nowadays, fullerenes (also polymerized, endohedral and exohedral fullerides), carbon onions (multi-shell fullerenes), nanotubes (dozens of varieties), whiskers, nanofibers, cones, nanohorns, nanodiamonds and other nanoscale carbons have been attracting much attention in the past 20–30 years. Graphene is the latest example and is now the most widely researched.

There are already thousands of carbon nanomaterials to choose from, and we need different materials to meet a variety of performance requirements. It will be shown on an example of supercapacitor electrodes that 0D and 1D nanoparticles, such as onions and nanotubes, deliver very high power due to fast ion sorption/desorption on their outer surfaces. Two-dimensional graphene offers higher charge-discharge rates compared to porous carbons and high volumetric energy density.

Three-dimensional porous activated, carbide-derived and templated carbon networks, having a high surface area and porosity in the Ångströms or nanometers range, can provide high energy density if the pore size is matched with the electrolyte ion size. Finally, carbon-based nanostructures further expand the range of nanomaterials available to us—recently discovered 2D transition metal carbides (MXenes) have already grown into a family with a dozen members in less than 3 years, and can challenge graphene in some applications.

 Yury Gogotsi is Distinguished University Professor and Trustee Chair in the department of materials science and engineering at Drexel University. He also holds courtesy appointments in the departments of chemistry and mechanical engineering & mechanics at Drexel University, and serves as director of the A.J. Drexel Nanomaterials Institute.

Spray-On Antennas Could Be the Tech Connector of the Future

Invisibly thin MXene antennas can be applied to a variety of substrates and perform better than antenna materials currently used in mobile devices.

Now, researchers at Drexel University have developed a method for creating nearly invisible antennas on almost any surface by literally spraying them on like paint. The antennas are made from a special two-dimensional metallic material called MXene. MXene powder can be dissolved in water to create a paint that is then airbrushed on. In tests, even a layer as thin as just 62 nanometers – thousands of times thinner than a sheet of paper – could communicate effectively. Performance maxed out at just 8 microns, a point at which the spray-on antennas worked just as well as those currently used in mobile devices and wireless routers.

MXene is one of the most sensitive gas sensors ever reported

MXene gas sensorsMXene is one of the most sensitive gas sensors ever reported that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person’s breath. Researchers from Drexel University and the Korea Advanced Institute of Science and Technology have made a discovery that could make our best “chemical noses” even more sensitive.
