Quote:Researchers have created the world's first graphene semiconductor. The joke goes that graphene can do everything but leave the lab, but in the last few years, this is no longer true. In this episode we'll see how scientists turned the best conductor known to man into a semiconductor, opening the door to faster, cooler and more efficient computing. Note: the resulting graphene was doped with pure oxygen within the experiment. Apologies for not explaining that critical part. Also another correction, I called "Georgia Institute of Technology" "Georgia Tech" , just wanted to clarify that.

Quote:Graphene Monoxide Bilayer As a High-Performance on/off Switching Media for Nanoelectronics

Abstract

The geometries and electronic characteristics of the graphene monoxide (GMO) bilayer are predicted via density functional theory (DFT) calculations. All the possible sequences of the GMO bilayer show the typical interlayer bonding characteristics of two-dimensional bilayer systems with a weak van der Waals interaction. The band gap energies of the GMO bilayers are predicted to be adequate for electronic device application, indicating slightly smaller energy gaps (0.418–0.448 eV) compared to the energy gap of the monolayer (0.536 eV). Above all, in light of the band gap engineering, the band gap of the GMO bilayer responds to the external electric field sensitively. As a result, a semiconductor-metal transition occurs at a small critical electric field (EC = 0.22–0.30 V/Å). It is therefore confirmed that the GMO bilayer is a strong candidate for nanoelectronics.

New technology funded by DARPA’s RE-NET program enables monitoring and stimulation of neurons using optical and electronic methods simultaneously

The technology demonstration draws upon three cutting-edge research fields: graphene, which earned researchers the 2010 Nobel Prize in Physics; super-resolved fluorescent microscopy, which earned researchers the 2014 Nobel Prize in Chemistry; and optogenetics, which involves genetically modifying cells to create specific light-reactive proteins.

RE-NET is part of a broader portfolio of programs within DARPA that support President Obama’s brain initiative.

Quote:Graphene-Based Nanomaterials: From Production to Integration With Modern Tools in Neuroscience

The promises of nanomedicine are extensive. Graphene (Gr), the first true two-dimensional material to exist in isolation, is the type of new nanomaterial that results in interest for novel biomedical applications. From Michael Chrichton’s tragic protagonist in The Terminal Man to the recent growth in start-up companies seeking to transfer consciousness, the fictive present and future call to mind visions of devices that enable neural interfacing and control.

Although these ideas may create questions as to ethics for neuroscience in the future, the current state-of-the-art for implanted devices is far more limited in scope. Progress in brain-computer interfaces holds great promise for patients following stroke (Ramos-Murguialday et al., 2013), to control prosthetic limbs (Hochberg et al., 2006; Donoghue et al., 2007), with the motor degeneration characteristic of Parkinson’s disease (Little et al., 2013), and for a variety of other disorders and diseases (Chaudhary et al., 2016). Gr may be poised for incorporation into such devices.

Quote:The worldwide estimate is that disposable masks or face shields are discarded at a rate of 3,4 billion per day. The presence of a diversity of plastics, toxic and cancerous compounds like perfluorocarbon, aniline, phthalate, formaldehyde, bisfenol A as well as heavy metals, biocides (zinc oxide, graphene oxide) and nanoparticles are found. An increasing number of environmental experts worry about the long-term effects. Most (85%) of the masks used worldwide are made in China where no environmental qualification is needed.

A total breakdown of these dangerous compounds is expected to last 450 years.
