Non-equilibrium Steady State Conductivity in Cyclo[18]carbon and Its Boron Nitride Analogue [PDF]
Phys. Chem. Chem. Phys. 22, 23998-24003 (2020), 2020 A ring-shaped carbon allotrope was recently synthesized for the first time, reinvigorating theoretical interest in this class of molecules. The dual $\pi$ structure of these molecules allows for the possibility of novel electronic properties. In this work we use reduced density matrix theory to study the electronic structure and conductivity of cyclo ...

Uniqueness in Calderon's problem with Lipschitz conductivities [PDF]
Duke Math. J. 162, no. 3 (2013), 497-516, 2011 We use X^{s,b}-inspired spaces to prove a uniqueness result for Calderon's problem in a Lipschitz domain under the assumption that the conductivity is Lipschitz. For Lipschitz conductivities, we obtain uniqueness for conductivities close to the identity in a suitable sense. We also prove uniqueness for arbitrary C^1 conductivities.

Functionalization of carbon nanotube yarn by acid treatment
International Journal of Smart and Nano Materials, 2014 Carbon nanotube (CNT) yarn was functionalized using sulfuric and nitric acid solutions in 3:1 volumetric ratio. Successful functionalization of CNT yarn with carboxyl and hydroxyl groups (e.g., COOH, COO–, OH, etc.) was confirmed by attenuated total ...
