Researchers from École Polytechnique Fédérale de Lausanne (EPFL) have developed an ultra-low power sensor to monitor health through the scanning of perspiration.

Director of Nanoelectronic Devices Laboratory (Nanolab) at EPFL, Adrian Ionescu—ECS published author in both the Journal of The Electrochemical Society and ECS Transactions—states that the new sensor can sync to your mobile device to alert you of your hydration, stress, and fatigue levels.

“The ionic equilibrium in a person’s sweat could provide significant information on the state of his health,” says Ionescu. “Our technology detects the presence of elementary charged particles in ultra-small concentrations such as ions and protons, which reflects not only the pH balance of sweat but also more complex hydration of fatigues states. By an adapted functionalization I can also track different kinds of proteins.”

A Consortium led by the Chemical and Allied Industries:
Creating Innovation Alliances for Business Growth

Submission deadline for presentations is June 5, 2015!

The Electrochemical Society is a partner on a grant awarded to the Ohio University Center for Electrochemical Research (CEER) from the National Institute of Standards and Technology (NIST) to facilitate the development of an Advanced Technology Roadmap focused on Electrochemical Pathways for Sustainable Manufacturing (EPSuM) with industrial company leadership. The goal of the roadmap is to establish an industry consortium to support, sustain, and enhance U.S. manufacturing capacity in the nation’s chemical industry and allied sectors through innovative electrochemical processes. Under the NIST Advanced Manufacturing Technology Consortia (AMTech) Program, the award will specifically support a roadmapping activity that could lead to funding to implement identified solutions.

We are working with Professor Gerri Botte, Center Director and Lisa Rooney, Industry Liaison at CEER to encourage participation in the roadmap process. Attached is a Call for Presenters for an Innovation Workshop in July. Due to the timelines for developing the roadmap, there is a short window to submit your application. Therefore, we have prepared a streamlined application that you can find here.

Proton OnSite, the world leader in commercializing proton exchange membrane (PEM) electrolysis, will be awarded the 2015 Industrial Electrochemistry & Electrochemical Engineering Division New Electrochemical Technology (NET) Award at the 227th ECS Meeting in Chicago.

The NET award was established in 1998 to recognize significant advances in industrial electrochemistry. The year’s award will be presented to Proton OnSite for the development of their C Series Hydrogen Generator. This new system has high strategic importance in that it continues to validate the technological advantage of PEM-based electrolysis at a scale similar to alkaline liquid based systems, without the disadvantages of the caustic electrolyte and high-pressure oxygen generation.

The new system has promising potential for the next generation of fueling stations for fuel cell bus demonstrations and for the refueling of small fleets of cars or forklift trucks.

The newly developed black silicon has the potential to simplify the manufacturing of solar cells due to the ability of the material to more efficiently collect light.

One of the roadblocks in developing a new, clean energy infrastructure lies in our ability to manufacture solar cells with ease and efficiency. Now, researchers from Rice University may have developed a way to simplify this process.

In Andrew Barron’s Rice University lab, he and postdoctoral student Yen-Tien Lu are developing black silicon by employing electrodes as catalysts.

The typical solar cell is made from silicon. By swapping that regular silicon for black silicon, solar cells gain a highly textured surface of nanoscale spikes that allows for a more efficient collection of light.

This from Rice University:

Barron said the metal layer used as a top electrode is usually applied last in solar cell manufacturing. The new method known as contact-assisted chemical etching applies the set of thin gold lines that serve as the electrode earlier in the process, which also eliminates the need to remove used catalyst particles.

The high-performance 3D microbattery is suitable for large-scale on-chip integration.

Engineers from the University of Illinois at Urbana-Champaign’s College of Engineering have developed a high-performance 3D microbattery applicable for large-scale on-chip integration with microelectronic devices.

“This 3D microbattery has exceptional performance and scalability, and we think it will be of importance for many applications,” said Paul Braun, professor of materials science and engineering at Illinois.

“Micro-scale devices typically utilize power supplied off-chip because of difficulties in miniaturizing energy storage technologies. A miniaturized high-energy and high-power on-chip battery would be highly desirable for applications including autonomous microscale actuators, distributed wireless sensors and transmitters, monitors, and portable and implantable medical devices.”

New research shows that we’re one step closer to being able to replicate the human brain outside of the body, which could lead to life-altering research into common conditions such as Alzheimer’s and Parkinson’s disease.

Project leader and ECS published author Sharath Sriram and his group have successfully engineered an electronic long-term memory cell, which mimics the way the human brain processes information.

“This is the closest we have come to creating a brain-like system with memory that learns and stores analog information and is quick at retrieving this stored information,” Sharath said.

Here at ECS, we strive to encourage research, discussion, critical assessment, and dissemination of scientific knowledge. What better way to do that in the digital age than with social networks?

Twitter has been one channel that scientists have adopted in the pursuit of disseminating information and advancing the science though education. Accordingly, we’ve compiled a short list of some of the best scientists to follow on Twitter.
