Single Step doping of Graphene

Applied Physics Letters – Single step, complementary doping of graphene A single-step doping method capable of high resolution n- and p-type doping of large area graphene is presented. Thin films of hydrogen silsesquoxane on exfoliated graphene are used to demonstrate both electron and hole doping through control of the polymer cross-linking process. This dual-doping is …

Progress in Understanding Regeneration in Salamanders

Shwann cells are shown here in a salamander limb. When the limb regrew after being amputated, only these cells wrapped around nerve fibers; other cell types did not turn into Shwann cells. Credit: D. Knapp/E. Tanaka The salamander is a superhero of regeneration, able to replace lost limbs, damaged lungs, sliced spinal cord — even …
