A team of scientists from Oak Ridge National Laboratory is using the precision of an electron beam to instantly adhere cathode coatings for lithium-ion batteries. This new development, as reported in the Journal of The Electrochemical Society, could lead to a leap in efficiency that saves energy, reduces production cost, and eliminates the use of toxic solvents.

This from ORNL:

The technique uses an electron beam to cure coating material as it rolls down the production line, creating instantaneous cross-links between molecules that bind the coating to a foil substrate, without the need for solvents, in less than a second.

“Typical curing processes can require drying machinery the length of a football field and expensive equipment for solvent recovery,” says David Wood, co-author of the study. “This approach presents a promising avenue for fast, energy-efficient manufacturing of high-performance, low-cost lithium-ion batteries.”

Every four years since 1987, scientists and engineers have been gathering in Honolulu, HI for the Pacific Rim Meeting on Electrochemical and Solid State Science, better known as PRiME. ECS has been committed to holding PRiME in Hawaii since its establishment to provide a central location for researchers from around the world, from the U.S. to Japan, to gather and discuss that latest scientific developments.

Because of his extensive experience in organizing PRiME and various other meetings across Latin American and Europe, ECS Executive Director Roque Calvo was invited to speak at the East Meets West Spring Education Tour, which is a meeting of executive directors, CEOs, and meeting planners, both of nonprofit and for profit companies, to discuss holding international conferences.

Hawaii’s talk show, Think Tech, reached out to Calvo during his most recent trip to Hawaii for the East Meets West Spring Education Tour to discuss electrochemistry, the clean energy movement, and open science. Watch the interview below.

A team of researchers at the University of Manchester – where graphene was first discovered and won the Nobel Prize – created a graphene-oxide membrane for desalination. The newly developed sieve can turn seawater into drinking water, demonstrating graphene’s ability to filter common salts from water, leading to affordable desalination technology.

Prior to this research, graphene-oxide molecules have garnered significant attention from the scientific community, demonstrating their potential to filter our small nanoparticles, organic molecules, and even large salts. However, researchers have not been able to use a graphene-oxide membrane in desalination technologies, which require very small sieves, until this development.

This from the University of Manchester:

Previous research at The University of Manchester found that if immersed in water, graphene-oxide membranes become slightly swollen and smaller salts flow through the membrane along with water, but larger ions or molecules are blocked.

The Manchester-based group have now further developed these graphene membranes and found a strategy to avoid the swelling of the membrane when exposed to water. The pore size in the membrane can be precisely controlled which can sieve common salts out of salty water and make it safe to drink.

William (Bill) David Brown, age 73, passed away on Thursday, March 30, 2017 in Fayetteville, AR.

As an advocate of education, Brown spent many years working as a professor. He started his career in academia at the University of New Mexico (1975-1977), followed by the University of Arkansas (1977-2008), where he served as Distinguished Professor, Head of the Electrical Engineering Department, and Associate Dean for Research in the College of Engineering.

Brown joined The Electrochemical Society in 1983. Throughout his life, he dedicated himself to ECS, serving as the Society’s president (2010-2011), vice president (2007-2010), and treasurer (1998-2000). Additionally, he served as the secretary, vice chair, and chair of the ECS Dielectric Science and Technology Division; and chaired the Society’s Education Committee (1994-2002), where he was instrumental in the initiation of the highly successful Student Poster Session held at each ECS meeting.

“Bill Brown was one of the Society’s finest leaders and a great teacher and mentor to me, and to many scientists and engineers in his field,” says Roque Calvo, ECS executive director. “He held an incredible number of top leadership positions in ECS but his work involving the Society’s Centennial and Free the Science fundraising campaigns could be his most notable contributions. He will be remembered for his contributions to our science and technology but more so for the character, integrity, and camaraderie that he brought to the Society.”

Brown also served on ECS’s Technical Affairs Committed (2007-2009), Ways and Means Committee (2007-2010), Finance Committee (1998-2002), Financial Policy Advisory Committee (1998-2007), and the Audit Subcommittee (2006-2007).

Joint research from the Universidad Carlos III de Madrid and the Council for Scientific Research reports the development of a new ceramic electrode for lithium-ion batteries that can lead to cheaper, more efficient, and safer conventional batteries.

“What we have patented are new ceramic electrodes that are much safer and can work in a wider temperature interval,” says Alejandro Varez, co-author of the research.

To achieve this result, the researchers made ceramic sheets by way of thermoplastic extrusion molds.

“This technique allows making electrodes that are flat or tube-shaped, and these electrodes can be applied to any type of lithium-ion battery,” Varez says.

According to the researchers, the cost of production is low and it could easily be adapted into current lithium-ion battery production, making this an easy technology to move quickly to industrialization.

Graphene could offer a new way to cool tiny chips in phones, computers, and other gadgets.

“You can fit graphene, a very thin, two-dimensional material that can be miniaturized, to cool a hot spot that creates heating problems in your chip,” says Eva Y. Andrei, a physics professor at Rutgers University. “This solution doesn’t have moving parts and it’s quite efficient for cooling.”

As electronics get smaller and more powerful, there’s an increasing need to for chip-cooling solutions. Researcher show in a paper published in the Proceedings of the National Academy of Sciences that using graphene combined with a boron nitride crystal substrate creates a very efficient cooling mechanism.

“We’ve achieved a power factor that is about two times higher than in previous thermoelectric coolers,” says Andrei.

The power factor refers to the effectiveness of active cooling. That’s when an electrical current carries heat away, as shown in this study, while passive cooling is when heat diffuses naturally.
