University of Michigan: Graphene Mechanics
Nov. 29, 2019
Graphene might be one of the most important materials in human history. As a monatomic layer of carbon atoms in a honeycomb lattice, graphene possesses extraordinary mechanical properties, in addition to other amazing properties. The mechanical properties are of extreme importance for several potential applications, including tailoring other properties with strain engineering. It is worth noting that the first fabrication of graphene is through mechanical exfoliation. As a fact, Mechanical exfoliation is still a popular approach for the scalable production of graphene.
In this Special Issue, we focus on the cutting-edge studies of graphene mechanics, from both theoretical and experimental investigations. In particular, this collection covers current areas of research that are concerned with the effect of the production method and/or the presence of defects upon the mechanical integrity of graphene, the work related to the effect of graphene deformation upon its electronic properties and the possibility of employing strained graphene in future electronic applications, and reviews of the experimental and theoretical results to date on mechanical loading of freely suspended or fully supported graphene. ...More>>>
Rice University: Old Newspapers Can Help Grow Nanotubes
Nov. 25, 2019
Old newspapers can be used as a low cost, eco-friendly material to grow single-walled carbon nanotubes on a large scale, says a study. Carbon nanotubes are tiny molecules with incredible physical properties that can be used in a huge range of things, such as conductive films for touchscreen displays, flexible electronics, fabrics that create energy and antennas for 5G networks.“Newspapers have the benefit of being used in a roll-to-roll process in a stacked form making it an ideal candidate as a low-cost stackable 2D surface to grow carbon nanotubes,” said lead researcher Bruce Brinson from the Rice University in the US. However, not all newspaper is equally good - only newspaper produced with sizing made from kaolin, which is china clay, resulted in carbon nanotube growth, said the researchers. ...More>>
Rutgers University: Graphene and Gold Biosensor May Help in Fighting Neurological Disorder
For the past few years, scientists have been working on potential applications for the ‘wonder material’ graphene in the field of neuroscience. Now, a team led by researchers from Rutgers University have created a graphene-gold biosensor that analyzes stem cells which may carve a new path for the medical sciences in the combatting of neurological disorders including Parkinson’s and Alzheimer’s disease. ..More>>
Columbia University - Breaking (and restoring) graphene's symmetry in a twistable electronics device
Nov. 21, 2019
A recent study from the Columbia University labs of James Hone (mechanical engineering) and Cory Dean (physics) demonstrates a new way to tune the properties of two-dimensional (2-D) materials simply by adjusting the twist angle between them. The researchers built devices consisting of monolayer graphene encapsulated between two crystals of boron nitride and, by adjusting the relative twist angle between the layers, they were able to create multiple moiré patterns.
Moiré patterns are of high interest to condensed matter physicists and materials scientists who use them to change or generate new electronic material properties. These patterns can be formed by aligning boron nitride (BN, an insulator) and (a semimetal) crystals. When these honeycomb lattices of atoms are close to alignment, they create a moiré , a nanoscale interference pattern that also looks like a honeycomb. This moiré superlattice alters the quantum mechanical environment of the conducting electrons in the graphene, and therefore can be used to program in the observed electronic properties of the graphene. ...More>>>
University of Illinois - Graphene: The more you bend it, the softer it gets
Nov. 18, 2019
New research by engineers at the University of Illinois combine atomic-scale experiments with computer modeling to determine how much energy is required to bend multilayer graphenea question that has eluded scientists since graphene was first isolated. The findings, reported in the journal Nature Materials.
Graphenea single layer of carbon atoms arranged in latticeis strongest material in the world and is so thin that it is flexible, the researchers said. It is considered one of the main ingredients of the technology of the future. ...More...
Winners Announced for the first Graphene Composites Design Contest
Nov. 20, 2019
Before lunch at the Graphene Innovation and Research Conference in Jackson, MS, finalists for the first Graphene Composites Design Competition pitched their ideas to a panel of judges. CEO Charles Chang served as announcer for the event and kept the audience and entrants in suspense as he presented the awards from Honorable mention to First place.
Hearty congratulations to first place winner Dr. Buddha Jayasena for the MVE Fusion Series medical application of graphene composites. Graphene Applications in Acoustic-Stirling Prime Movers and Heat Pumps was co-authored with Dr. Doug Wilcox. Jayasena is a mechanical engineer with nine years of experience in the manufacturing industry and R&D settings, and earned his PhD in Philosophy, Mechanical Engineering at Nanyang Technological University in 2013. Wilcox is a development engineer who earned his PhD in Acoustics at Penn State University in 2017 and is employed with Jayasena at Chart Industries, Inc.
The winner of second place stole the hearts of many as 10 year old genius Liam Mooney pitched his idea with clarity and a touch of humor as he described a graphene composite coating for gloves. His invention will enhance grip and allow the wearer to use their electronic devices while wearing gloves. He plans to develop his prototype and return for Phase II of the competition in Washington, DC next year.
Third place winner Alexander Lopez entered the competition with fellow University of Mississippi student John Malone. Their invention is a high throughput Graphene Oxide membrane fabrication system for global expansion of desalination systems.
Allison Buchanan, CEO at The Focus Group on the Gulf Coast and graduate of The University of Mississippi, won fourth place for her innovative idea to use graphene as an additive for longevity and durability of acrylic fingernail manicures.
Fifth place winning team Daniel Scott and Farbod Moghaddam offered their idea to mix graphene with fingernail polish, creating a product a non-toxic, high performance product.
Honorable Mention was awarded to Adam Dick for his graphene coating idea.
The contest was judged by Dr. Thomas Nosker of Rutgers University, Tom Jeff of Innovate Mississippi, Dr. Elena Polyakova of Graphene 3D Laboratories, and Mississippi businessman Gilbert Gerard.
