Anasori Wins “Materials Today” Cover Competition

Continuing his history of success in visualization and imaging competitions, Babak Anasori’s submission to the Materials Today cover competition was selected as a winner and will be featured on the cover of a 2014 issue of the journal. Congratulations to Babak! See all of the winning entries here.

Colorized SEM image shows Nb2O5 layers coated on graphene aerogel. The graphene/Nb2O5 structure was formed in a one-step hydrothermal process. This freestanding and mechanically robust composite is used as a three-dimensional (3D) supercapacitor electrode, taking advantage of high conductivity of the graphene aerogel network and pseudocapacitive behavior of Nb2O5, which leads to a high energy density. Materials Today 2013 Cover Competition Winner. Synthesis: M. Beidaghi; SEM and Coloring: B. Anasori

“Green Supercapacitor” Paper Featured by ChemSusChem

“Development of a Green Supercapacitor Composed Entirely of Environmentally Friendly Materials,” by Nanomaterials Group members Boris Dyatkin, Maria Lukatskaya, Majid Beidaghi and Min Heon, along with NMG alum Volker Presser, is featured on the back cover of the ChemSusChem December issue. The back cover image, designed by fellow NMG member Kristy Jost, shows the structure and system integration possibilities of an electrical double layer capacitor composed entirely of environmentally friendly materials. See the image here.

The research team led by Professor Gogotsi found green alternatives for each key component of a supercapacitor. By using such accessible materials as cellulose acetate, graphite foil, and polyvinyl alcohol to design a complete nontoxic system, the resulting energy storage device operates at high levels and can be safely disposed or incinerated after use.
