The worst collateral damage of COVID-19 is the decimation of global commerce, and trade shows have been hit especially hard – tough to practice “social distancing” with a few thousand people (or more) clustered together. And one of the most unfortunate victims of this new, quarantined reality was the 2020 Ap

Rice University theorists have calculated flexoelectric effects in double-walled carbon nanotubes. The electrical potential (P) of atoms on either side of a graphene sheet (top) are identical, but not when the sheet is curved into a nanotube. Double-walled nanotubes (bottom) show unique effects as band gaps in inner and outer tubes are staggered.
One nanotube could be great for electronics applications, but there's new evidence that two could be tops.
Rice University engineers already knew that size matters when using single-walled carbon nanotubes for their electrical properties. But until now, nobody had studied how electrons act when confronted with the R

Increasing the efficiency of Solid oxide fuel cells (SOFCs)
In this post-industrialization age, electricity has become the backbone of our society. However, using fossil fuels to generate it is not the best option because of their limited availability and harmful nature. In the last two decades, significant efforts have been made to develop techniques to foster sustainable en
