The Samsung Galaxy Note 7 has recently been in the headlines for safety concerns pertaining to its lithium-ion battery. Now, a lawsuit filed in California claims that the issues extend beyond the Note 7, and that many other generations of Samsung smartphones “pose a risk of overheating, fire, and explosion.”

While Samsung claims that the Li-ion safety issues are isolated to only the Note 7, researchers in the field of energy storage are still looking for a way to develop an efficient, non-combustible battery. CBS recently stopped by the University of Maryland to discuss just that with ECS member Erich Wachsman.

Watch the full CBS interview.

In an effort to build safer batteries, Wachsman and his group at the University of Maryland are focusing their research efforts on lithium conducting ceramic discs, which can handle thousands of degrees without any issues.

“Because it’s ceramic, it’s actually not flammable,” says Wachsman, director of the university’s Energy Research Center. “You cannot burn ceramic.”

Since the rise of Li-ion battery safety in the news, Wachsman’s research has received more attention from industry. He and his group are currently working on scaling up the technology.

Last week, EV superpower Tesla announced its latest product: roof tiles with built-in solar cells. By merging technological performance with aesthetics, Tesla hopes to offer consumers solutions to make their homes more energy self-sufficient.

Using PV roofing material instead of traditional rooftop solar panels helps the company consolidate costs. According to Tesla CEO Elon Musk, there are between four and five million new roofs constructed in the United States each year, which gives him a broad market.

Musk says that the roof tiles have the potential to integrate with Tesla’s Powerwall battery as well as the company’s electric cars, providing customers new, interconnected energy experiences. The CEO claims that roofs made from the new solar material would last up to three times as long as a typical 20-year-cycle roof and be more impact resistant.

However, critics of Tesla’s latest move highlight potential issues related to many different factors, including: location, energy storage capabilities, the practicality and cost of replacing a roof, and the difficulty in integrating PV technology into infrastructure. Tesla has not specified the technology behind their solar cells, but have claimed that they achieve 98 percent of the efficiency of traditional solar panels.

Researchers are shedding new light on cell biology with the development of a graphene sensor to monitor changes in the mitochondria.

The one-atom-thin layer of carbon sensor is giving researchers a new outlook into the process known as programmed cell death in mitochondria. The mitochondrion, which is found in most cells, has been known as the powerhouse of the cell due to its ability to metabolize and create energy for cells. However, the new researcher out of University of California, Irving shows that that convention wisdom on how cells create energy is only half right.

This from UC Irving:

[Peter] Burke and his colleagues tethered about 10,000 purified mitochondria, separated from their cells, to a graphene sensor via antibodies capable of recognizing a protein in their outer membranes. The graphene’s qualities allowed it to function as a dual-mode sensor; its exceptional electrical sensitivity let researchers gauge fluctuations in the acidity levels surrounding the mitochondria, while its optical transparency enabled the use of fluorescent dyes for the staining and visualization of voltage across the inner mitochondrial membranes.

A team of researchers from the University of California, San Diego, led by ECS member Joseph Wang, recently developed new magnetic ink that can be used to make self-healing batteries, electrochemical sensors, and wearable, textile-based electrical circuits.

The ink is made up of microparticles set up in a certain configuration by a magnetic field. The particles on each respective side of the tear in a circuit are then attracted towards each other, resulting in the self-healing effect. The devices have the ability to repair tears as wide as 3 millimeters, which is a record in the field of self-healing systems.

“Our work holds considerable promise for widespread practical applications for long-lasting printed electronic devices,” Wang says.

While there are other self-healing materials in the field, they require an external trigger to start the process, which takes anywhere from a few min to days. The new work does not require any outside catalyst and works in 0.05 seconds

My name is Andrew Ryan. For the past eight months, I served as a Membership Services Intern at ECS under the direction of Beth Fisher. Though I worked on many different projects throughout my time at ECS, my primary contribution was writing membership related posts for the ECS website’s Redcat Blog. A great deal of the posts written over the course of the past eight months with the byline “ECS Staff” were written by me.

An English major who graduated from The College of New Jersey this past May, I was absolutely honored to have the opportunity to write for a website with such a thriving viewership. It was beyond fulfilling to be able to apply my passion for writing in a professional environment.

But ECS was more to me than a writing outlet. It was more to me than a desk job or a resume line. It was a truly, positively rewarding experience.

Let me tell you why.
