Coexistence of both edge plane and basal plane in graphite often hinders the understanding of lithium ion diffusion mechanism. In this report, two types of graphene samples were prepared by chemical vapor deposition (CVD): (i) well-defined basal plane graphene grown on Cu foil and (ii) edge plane-enriched graphene layers grown on Ni film. Electrochemical performance of the graphene electrode ca...

The background shows a water layer on the graphene containing Stone–Wales and double vacancy defects. The structural and electronic properties of the systems have been studied by density functional tight-binding method, to understand graphene's stable electronic characteristics. Defects are inevitably present in graphene and can alter its properties and thus its applications. Interestingly, we ...

introduction here we report an unusual case of massive stone formation in augmented urinary bladder. case presentation a 25-year-old man presented with recurrent urinary tract infection ten years after augmentation cystoplasty after a complex pelvic fracture urethral distraction defect. on evaluation by ultrasonography, x-ray, and computed tomography of abdomen showed large burden of stones in ...

We investigated the effects of applying an external electric field on electronic properties Stone-Wales (SW) defective carbon-boron-nitride nanotubes (CBN) using first principles calculations. The CBN were modeled by introducing Stone–Wales defects in boron-nitride segment (BN-SW), carbon (C-SW), and interface (CBN-SW). Initially, we studied formation energies structural stability for all model...

Outstanding thermal transport properties of carbon nanotubes (CNTs) qualify them as possible candidates to be used as thermal management units in electronic devices. However, significant variations in the thermal conductivity (κ) measurements of individual CNTs restrict their utilizations for this purpose. In order to address the possible sources of this large deviation and to propose a route t...

In the fabrication and processing of silicene monolayers, structural defects are almost inevitable. Using ab initio calculations, we systemically investigated the structures, formation energies, migration behaviors and electronic/magnetic properties of typical point defects in silicene, including the Stone-Wales (SW) defect, single and double vacancies (SVs and DVs), and adatoms. We found that ...
