According to the Georgia Institute of Technology, crab shells and trees may soon replace the flexible plastic packaging used to keep food fresh. The innovative process involves spraying multiple layers of chitin from crab shells and cellulose from trees to form a flexible film similar to plastic packaging film. Once fully dried, the material is flexible, strong, transparent, and compostable.

Not only will these lifeforms become a source of sustainable and renewable wrapping, but they will also help improve food quality. Compared to conventional plastic packaging, the new technology offers a 67 percent reduction in oxygen permeability, allowing food to stay fresh even longer.

(Eric Wachsman will be presenting Safe, High-Energy-Density, Solid-State Li Batteries at AiMES 2018 in Cancun, Mexico on October 1, 2018.)

Behind the wheel of a ’68 Dodge Charger, Eric Wachsman discovered his passion for clean energy technology. He was a teenage boy in high school, and the open road was calling out to him.

“I just lived for cars,” says Wachsman, who serves on the ECS board of directors. “I could not wait to get my first car.”

So when he hit the road in his $1,500 hot rod, loaded with a holley double pumper carburetor, headers. “You name it.” He was thrilled. “That thing was the fastest thing around.”

However, life on the road soon came to a screeching halt.

Nineteen sixty-eight marked a year of tragedy but also of transformation. It may be 50 years in our past, but what occurred that year is still very much alive with us today. Here are our top 5 reasons why the scientific advances of that year are super “groovy” in our book:

5. Patent for the jacuzzi whirlpool hot tub granted

Roy Jacuzzi realized early on that the market for leisure and fitness was a growing one. He set out to create a bathtub that allowed enough room to offer “a relaxing soak,” according to Jacuzzi Inc.’s company history page. With that, the first bathtub with a built-in whirlpool system was born. The laid-back culture of California in the 1970s turned out to be the perfect launching ground for the now widely appreciated and known jacuzzi.

4. Apollo 8 is the first manned spacecraft to orbit the moon

Jim Lovell, Bill Anders, and Frank Borman became the first human beings to orbit another world. According to NASA, on Christmas Eve 1968 the three men were the first to orbit the moon and see  Earth as a whole planet. With that, Jim Lovell confirmed, “there is a Santa Claus.”

An online platform that had once offered a voice to scientists – to join in on debates and discussions of other scientists and inquisitive minds – may now be a thing of the past. Social news website Reddit hosts r/science, one of the world’s largest online science communities, which ran a popular Ask Me Anything Q&A (AMA) series that picked the brains of academics about topics like climate change, physics, and astronomy has come to an end. This was all due to a change in Reddit’s algorithm, changing how posts were ranked and making it nearly impossible to compete with the charm of cute animal GIF’s in the competition of upvotes.

The demise of the Ask Me Anything Q&A series is considered a major setback for the science community. The forum grew to nearly 19 million users, now left with no other platform that offers quite the same reach, accessibility, and engagement.

“With flat-earthers, anti-vaxxers, climate change deniers, and the rest of the anti-science brigade making their views heard in almost every corner of the internet, it’s a difficult time for those who value insightful discussion of peer-reviewed science online,” says Alastair McCloskey, a digital content coordinator in the Faculty of Social Sciences at the University of Sheffield.

Hydro-Québec (an ECS institutional member) and the U.S. Army Research Laboratory have announced a breakthrough in the lithium-ion battery materials field, publishing their research results in the Journal of Power Sources. Using a cathode made with new high voltage safe materials, the researchers have achieved a world first: building a 1.2 Ah lithium-ion cell with a voltage of 5 V.

“With the high voltage of this new cell, we can reach a very high energy density,” says Karim Zaghib, General Director of the Center of Excellence in Transportation Electrification and Energy Storage. “This highly desirable property can improve batteries used in a wide range of applications.” Army Research Laboratory scientists Jan Allen and Richard Jow, also inventors of this high voltage cathode material, believe that the high cell voltage can, in addition to enabling high energy density, improve the design of devices.

Lithium-ion batteries are widely used to power many electronic devices, including smartphones, medical devices and electric vehicles. Their high energy density, excellent durability and lightness make them a popular choice for energy storage. In response to the growing demand for their use in a wide range of products, there are many teams working to improve their storage capacity. In particular, there is great interest in developing new compounds that could increase energy storage capacity, stability and lifespan. That is why the innovation announced today has such a strong commercial potential.

Sustainability is at the core of the research that is published in the ECS Digital Library. Electrochemists and solid state scientists and engineers are our best hope of developing the technologies that will make a difference. They are the masterminds behind the lithium batteries that run all of our mobile devices, they developed the first fuel cells and photovoltaics, and they are on the cutting edge of current research in generating and storing energy from renewable sources like solar, biofuels, even waste papaya and tomatoes. From creating more efficient systems to discovering new energy sources, electrochemists and solid state scientists are behind the most critical innovations in sustainability and renewable energy. That is why, we at ECS are excited to celebrate Earth Day this weekend.

If you still need ideas on how to spend the day, here are the top five things to do:

1. Volunteer

Help clean up a local park, beach, or river! What better way to show your appreciate for the Earth than to help her look her best? This will also help ensure the local plants and animals live a healthier life. Electrochemists and solid state scientists and engineers are tackling waste and improving living conditions around the world through novel reuse systems.

ECS member, Dr. Boryann Liaw has turned waste papaya into sugar-air batteries. Electrochemists are turning food waste like tomatoes and bread mold into energy sources for batteries and fuel cells.

Researchers at KTH have successfully tested a new material that can be used for cheap and large-scale production of hydrogen – a promising alternative to fossil fuel.

Precious metals are the standard catalyst material used for extracting hydrogen from water. The problem is these materials – such as platinum, ruthenium and iridium – are too costly to make the process viable. A team from KTH Royal Institute of Technology recently announced a breakthrough that could change the economics of a hydrogen economy.

Led by Licheng Sun, professor of molecular electronics at KTH Royal Institute of Technology, the researchers concluded that precious metals can be replaced by a much cheaper combination of nickel, iron and copper (NiFeCu).

In order to power entire communities with clean energy, such as solar and wind power, a reliable backup storage system is needed to provide energy when the sun isn’t shining and the wind doesn’t blow.

One possibility is to use any excess solar- and wind-based energy to charge solutions of chemicals that can subsequently be stored for use when sunshine and wind are scarce. At that time, the chemical solutions of opposite charge can be pumped across solid electrodes, thus creating an electron exchange that provides power to the electrical grid.

The key to this technology, called a redox flow battery, is finding chemicals that can not only “carry” sufficient charge, but also be stored without degrading for long periods, thereby maximizing power generation and minimizing the costs of replenishing the system.

A collaborative team of researchers from Shinshu University in Japan have found a new way to curb some of the potential dangers posed by lithium ion batteries.

The team was led by Susumu Arai, a professor of the department of materials chemistry and head of Division for Application of Carbon Materials at the Institute of Carbon Science and Technology at Shinshu University.

These batteries, typically used in electric vehicles and smart grids, could help society realize a low-carbon future, according the authors. The problem is that while lithium could theoretically conduct electricity at high capacity, lithium also results in what is known as thermal runaway during the charge and discharge cycle.

“Lithium metal is inherently unsuitable for use in rechargeable batteries due to posing certain safety risks,” said Arai. “Repeated lithium deposition/dissolution during charge/discharge can cause serious accidents due to the deposition of lithium dendrites that penetrate the separator and induce internal short-circuiting.”

Engineers have, for the first time, come up with a way to safely charge a smartphone wirelessly using a laser.

A narrow, invisible beam from a laser emitter can deliver charge to a smartphone sitting across a room—and potentially charge the phone’s battery as quickly as a standard USB cable.

To accomplish this, the researchers mounted a thin power cell to the back of a smartphone, which charges the smartphone using power from the laser.
