From artificial limbs to cochlear implants, biomedical advancements are opening up new opportunities for health care. Now, researchers from the University of Delaware are working to further improve the lifetime and effectiveness of those biomedical devices by improving communication between the technology and neural tissue.

In order to improve the devices, researchers worked to develop a direct interfacing material to improve communication between the device and the body. For this, the team focused on a conjugated polymer known as PEDOT.

Compared to other methods, surface modification through electro-grafting takes just minutes. Another advantage is that a variety of materials can be used as the conducting substrate, including gold, platinum, glassy carbon, stainless steel, nickel, silicon, and metal oxides.

“Our results suggest that this is an effective means to selectively modify microelectrodes with highly adherent and highly conductive polymer coatings as direct neural interfaces,” says David Martin, lead researcher.

A team of researchers from Texas A&M University is looking to take the negative impact of excessive levels of carbon dioxide in the atmosphere and turn it into a positive with renewable hydrocarbon fuels.

Greenhouse gasses trap heat in the atmosphere and therefore impact global temperatures, making the planet warmer. Carbon dioxide, the most common greenhouse gas, is emitted into the atmosphere upon burning fossil fuels, solid waste, and wood products, and makes up 81 percent of all greenhouse gas emissions in the U.S.

“We’re essentially trying to convert CO2 and water, with the use of the sun, into solar fuels in a process called artificial photosynthesis,” says Ying Li, principal investigator and ECS member. “In this process, the photo-catalyst material has some unique properties and acts as a semiconductor, absorbing the sunlight which excites the electrons in the semiconductor and gives them the electric potential to reduce water and CO2 into carbon monoxide and hydrogen, which together can be converted to liquid hydrocarbon fuels.”

This from Texas A&M University:

The first step of the process involves capturing CO2 from emissions sources such as power plants that contribute to one-third of the global carbon emissions. As of yet, there is no technology capable of capturing the CO2, and at the same time re-converting it back into a fuel source that isn’t expensive. The material, which is a hybrid of titanium oxide and magnesium oxide, uses the magnesium oxide to absorb the CO2 and the titanium oxide to act as the photo-catalyst, generating electrons through sunlight that interact with the absorbed CO2 and water to generate the fuel.

Sometimes the biggest advancements are the smallest in size.

A multidisciplinary team from Sandia National Laboratories recently demonstrated that notion by using nanoparticles and a nanoconfinement system to improve the performance of hydrogen storage materials. The researchers believe that this development is a step in the right direction to improve efficiency of hydrogen fuel cell electric vehicles.

Currently, hydrogen fuel cell electric vehicles store hydrogen as a high-pressure gas. However, the researchers argue that a solid material would be able to act like a sponge, with the ability to absorb and release hydrogen more efficiently. Using a hydrogen storage material of this nature could increase the amount of hydrogen able to be stored in a vehicle. In order to be efficient and competitive in the transportation sector, a hydrogen fuel cell electric vehicle would have to be able to travel 300 miles before refueling.

“There are two critical problems with existing sponges for hydrogen storage,” says Vitalie Stavila, co-author of the study and past ECS member. “Most can’t soak up enough hydrogen for cars. Also, the sponges don’t release and absorb hydrogen fast enough, especially compared to the 5 minutes needed for fueling.”

On March 4, 2017, ECS will be celebrating Open Data Day! For 2017, this global initiative focuses on four key areas that open data can contribute to: open research data, tracking public money flows, open data for the environment, and open data for human rights.

What is open data? Open data is the revolutionary concept that some data should be available for public use without legal or fiscal restrictions. ECS’s Free the Science initiative aligns categorically with open research data and open data for the environment. This ECS initiative is fighting to bring science and technology into the information sharing era; as technology makes information rapidly more available, the way in which data is accessible and presented becomes evidently more important for scientific advancement. In light of this, ECS is actively seeking ways to make our research open to expedite innovation and find solutions for environmental issues and other technically relevant areas. In addition to this, we are seeking to change the way that scholarly communication among scientists is exchanged and socialized. In the coming months, keep your eye out for big announcements in these areas which are expected to help us accomplish those goals!

Do you want to participate in Open Data Day but don’t know how? On Thursday, March 2 through Saturday, March 4, ECS will be circulating a survey to determine our field’s specific needs in the realm of accessibility to data and research. The best way to contribute to open data is by sharing your knowledge and helping us to understand the accessibility needs of our researchers.

In June 2016, the International Meeting on Lithium Batteries (IMLB) in Chicago successfully celebrated 25 years of the commercialization of lithium-ion batteries. According to Doron Aurbach, technical editor of the Batteries and Energy Storage topical interest area of the Journal of The Electrochemical Society, research efforts in the Li-battery community continues to provide ground-breaking technological success in electromobility and grid storage applications. He hopes this research will continue to revolutionize mobile energy supply for future advances in ground transportation.

ECS has published 66 papers for a new IMLB focus issue in the Journal of The Electrochemical Society. All papers are open access at no charge to the authors and no charge to download thanks to ECS’s Free the Science initiative!

The peer review process is the heart of scholarly communication, assuring the publication of high-quality papers and strengthening the public’s perception of the science. Through peer review, editors, reviewers, and authors work together to ensure the work is coherent, rigorous, and adds to the scientific knowledge base.

However, peer review is not flawless. Namely, the labor intensive review-revise-resubmit process can be time consuming, potentially hampering scientific progress due to publication delay.

“Peer review is everything,” says Michael Hickner, member of the ECS Editorial Advisory Committee and professor at Pennsylvania State University. “However, it can be inefficient and sometimes mistakes happen, but it is our system. Peer review is our gold standard and a tradition of the academic community.”

To help combat some of the issues facing the peer review process today and further strengthen ECS’s manuscript review process, the Society has established the Editorial Advisory Committee to accelerate the peer review process and resolve discrepancies between reviewers on content quality.

“The core goal of the Editorial Advisory Committee is to lend expertise and perspective to the editors and associate editors,” Hickner says, who specializes in membranes for fuel cells and batteries. “I’m a technical consultant and I can weigh in on key papers; perhaps like a trusted super-reviewer.”

Rice University researchers have modeled a nanoscale sandwich, the first in what they hope will become a molecular deli for materials scientists.

Their recipe puts two slices of atom-thick graphene around nanoclusters of magnesium oxide that give the super-strong, conductive material expanded optoelectronic properties.

Rice materials scientist Rouzbeh Shahsavari and his colleagues built computer simulations of the compound and found it would offer features suitable for sensitive molecular sensing, catalysis and bio-imaging. Their work could help researchers design a range of customizable hybrids of two- and three-dimensional structures with encapsulated molecules, Shahsavari said.

The research appears this month in the Royal Society of Chemistry journal Nanoscale.

The scientists were inspired by experiments elsewhere in which various molecules were encapsulated using van der Waals forces to draw components together. The Rice-led study was the first to take a theoretical approach to defining the electronic and optical properties of one of those “made” samples, two-dimensional magnesium oxide in bilayer graphene, Shahsavari said.

“We knew if there was an experiment already performed, we would have a great reference point that would make it easier to verify our computations, thus allowing more reliable expansion of our computational results to identify performance trends beyond the reach of experiments,” Shahsavari said.

John Goodenough may be 94-years old, but he shows no sign of slowing down. Now, the co-inventor of the lithium-ion battery has developed the first all-solid-state battery cells that could result in safer, longer-lasting batteries for everything from electric cars to grid energy storage.

“Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted,” Goodenough says in a statement. “We believe our discovery solves many of the problems that are inherent in today’s batteries.”
