(Phys.org)—Graphene has been grown from materials as diverse as plastic, cockroaches, Girl Scout cookies, and dog feces, and can theoretically be grown from any carbon source. However, scientists are still looking for a graphene ...
(Phys.org)—When exposed to air, a luminescent 2D material called molybdenum telluride (MoTe2) appears to decompose within a couple days, losing its optical contrast and becoming virtually transparent. But when scientists ...
(Phys.org)—For the first time, scientists have integrated transparency into freestanding, flexible graphene paper (FFT-GP), and demonstrated that the new material can greatly improve the performance of supercapacitors.
(Phys.org)—Nanoionics is a sub-field of nanotechnology that is concerned with nanoscale phenomena involving migration of ions in solid maters. Thus far, however, the confinement of ionic currents to predefined paths in a ...
(Phys.org)—Scientists have simulated the explosion of a modified buckminsterfullerene molecule (C60), better known as a buckyball, and shown that the reaction produces a tremendous increase in temperature and pressure within ...
By dipping small pieces of an ordinary kitchen sponge into solutions of nanoscale electrode materials, scientists have created a light-weight, low-cost supercapacitor that benefits from the sponge's porous structure. The ...
(Phys.org) —Graphene has already been demonstrated to be useful in Li-ion batteries, despite the fact that the graphene used often contains defects. Large-scale fabrication of graphene that is chemically pure, structurally ...
(Phys.org) —Carbon – the chemical basis of all known life and an element known as far back as the 8th century BC – exists in a range of forms, or allotropes, with remarkably diverse properties. (Diamond, for example, is transparent ...
(Phys.org) —What happens when you shoot multiwalled carbon nanotubes (MWCNTs) out of a gun onto an aluminum target at a velocity of more than 15,000 mph? Scientists finally have the answer. If a nanotube reaches the target ...
(Phys.org) —Achieving a balance between low-cost fabrication and high efficiency is key to the future success of solar cells. Over the past several years, researchers have been working on developing low-cost methods to manufacture ...
