First Graphene-Based Flexible Display Produced

"This is a significant step forward to enable fully wearable and flexible devices ." -Andrea Ferrari, Director of the Cambridge Graphene Centre

“This is a significant step forward to enable fully wearable and flexible devices .”
-Andrea Ferrari, Director of the Cambridge Graphene Centre

There has been quite the buzz around graphene lately. With this material being among the strongest and most lightweight known, it has the potential to revolutionize industries from healthcare to electronics. And revolutionize is exactly what the Cambridge Graphene Centre (CGC) and Plastic Logic have set out to do.

With the CGC’s graphene expertise and Plastic Logic’s already developed technology for flexible electronics, the two came together to demonstrate the first graphene-based flexible display.

This from University of Cambridge:

The new prototype is an active matrix electrophoretic display, similar to the screens used in today’s e-readers, except it is made of flexible plastic instead of glass. In contrast to conventional displays, the pixel electronics, or backplane, of this display includes a solution-processed graphene electrode, which replaces the sputtered metal electrode layer within Plastic Logic’s conventional devices, bringing product and process benefits.

Current member of ECS, Xiaodong Xu, has made a huge contribution to the field of electrochemical science with the creation of atomically seamless, thinnest-possible semiconductor junctions.

Xu, along with the scientists at the University of Washington, believe their semiconductor – coming in at only three atoms thick – is the most slender possible, a new class of nanoscale materials.

This from the University of Washington:

The University of Washington researchers have demonstrated that two of these single-layer semiconductor materials can be connected in an atomically seamless fashion known as a heterojunction. This result could be the basis for next-generation flexible and transparent computing, better light-emitting diodes, or LEDs, and solar technologies.

Read the full article here.

“Our experimental demonstration of such junctions between two-dimensional materials should enable new kinds of transistors, LEDs, nanolasers, and solar cells to be developed for highly integrated electronic and optical circuits within a single atomic plane,” Xu said.

The research was published online this week in Nature Materials.

The Protest for Net Neutrality

Net Neutrality

On September 10th, sites across the web will display an alert with a symbolic “loading” symbol and promote a call to action for users to push comments to the FCC, Congress, and the White House.

Today a group of popular websites that rely on speedy Internet have launched an online protest against proposed changes to “net neutrality.” They call themselves Team Internet and are comprised of popular websites, such as Netflix, Vimeo, Reddit, and WordPress – just to name a few.

The protest aims to fight policy changes via the U.S. Federal Communications Commission that would overturn a 2010 ruling that required Internet service providers to treat all web traffic the same.

This from TIME:

Since May, the FCC has been weighing changes to its regulations on “net neutrality” — the 2010 rules requiring Internet service providers to treat all web traffic the same. The changes would allow cable companies to grant paying customers faster service, but ban them from slowing down, or throttling, the access of nonpaying companies. The FCC has already lost two court cases brought by cable companies who have challenged the legality of its existing net-neutrality rules.

ECS fights a similar battle in the realm of publication. In order to avoid the dissemination of science and research that creates a world of haves and have-nots, ECS fully supports open access publishing.

Introducing Mr. Toilet

Meet Mr. Toilet

“What you don’t talk about, you cannot improve.”
-Jack Sim

Everybody poops – but not everybody has a place to do so. Sanitation is a growing – and often times deadly – crisis in the developing world, and the silence on this issue must be broken.

Let sanitation superhero Jack Sim tell you why you should care about this issue. He is, after all, the one and only Mr. Toilet.

This from the Bill & Melinda Gates Foundation:

The need for better sanitation in the developing world is clear. Forty percent of the world’s population—2.5 billion people—practice open defecation or lack adequate sanitation facilities, and the consequences can be devastating for human health as well as the environment. Even in urban areas, where household and communal toilets are more prevalent, 2.1 billion people use toilets connected to septic tanks that are not safely emptied or use other systems that discharge raw sewage into open drains or surface waters.

ECS is partnering with the Bill & Melinda Gates Foundation to enable universal access to sustainable sanitation services with innovative solutions to funding research.

Join us in Cancun for the 2014 Electrochemical Energy and Water Summit, where more than $200,000 will be available as seed funding for projects that address critical technical gaps in global sanitation.

Find out how you could be a part of this brainstorming workshop and help solve some of the most challenging issues in the world today.

Become a NeXXt Scholar Today

The NeXXt Scholars Program was launched by Secretary of State Hillary Rodham Clinton in December 2011.

The New York Academy of Sciences in partnership with the U.S. Department of State and a consortium of 38 women’s colleges launched the NeXXt Scholars Program, now entering its third year, to help engage and advance American women and women from countries with predominantly Muslim populations in pursuit of undergraduate degrees in science, technology, engineering, and mathematics (STEM) academic fields. In order to accomplish this goal, the Academy will provide partnership, mentorship, and networking support for these NeXXt Scholars by way of a STEM Fellow who will serve as a one-to-one mentor.

Applications for 2014 STEM Fellow positions are being accepted until September 20th.

Find more information or submit an application today.

Free the Engineering!

Vijay Ramani

Co-editor of Interface, Vijay Ramani, talks about open access publishing in this letter from the editor.

The following is an article from the latest issue of Interface by co-editor Vijay Ramani.

Late last year, I accepted the invitation to become co-editor of Interface safe in the knowledge that I would not actually be called upon to do anything for the foreseeable future.* Thanks to the outstanding ECS staff and conscientious guest editors and authors, this happy state of affairs has persisted until now. But just as “even the weariest river winds somewhere safe to sea,” so it is that the inevitable passage of time has brought upon a situation wherein actual effort is required on my part, viz. this editorial. The increasingly plaintive entreaties from our admirably patient Director of Publications seeking the contents of this column can no longer, in good conscience, be ignored or fobbed off with feeble excuses.

Read the rest.

Electropolishing of Stainless Steels – Kosmač, Euro Inox
Electropolishing is a chemical surface finishing technique, by which metal is electrolytically removed, ion by ion, from the surface of a metal object. The primary objective is to minimize microroughness, thus dramatically reducing the risk of dirt or product residues adhering and improving the cleanability of surfaces. Electropolishing is also used for deburring, brightening, and passivating. The process exposes an undisturbed, metallurgically clean surface, eliminating thermal stress and surface roughening, and improving the corrosion resistance.
