The 2019 Nobel Prize in Chemistry was awarded to John B. Goodenough (The University of Texas at Austin), M. Stanley Whittingham (Binghamton University, State University of New York), and Akira Yoshino (Asahi Kasei Corporation and Meijo University) “for the development of lithium-ion batteries”. With the creation and subsequent optimization of lithium-ion batteries to make them more powerful, lighter, and more robust, the seminal work of Goodenough, Whittingham, and Yoshino has had a profound impact on our modern society. This ubiquitous technology has revolutionized our daily lives by paving the way for portable electronics and made renewable energy sources more viable. While attempts to improve the performance of batteries continue, the lithium-ion battery has remained the world’s most reliable battery system for more than 40 years. The three winners will each receive an equal share of the roughly $1 million award. At 97, Goodenough is now the oldest person ever to win the Nobel Prize.

“A long-awaited recognition for the creators of lithium-ion batteries has come true. The electrochemistry and material science communities – and the greater chemistry community as a whole – are excited to hear the news of the 2019 Nobel Prize award to John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino for their pioneering contribution to lithium-ion batteries,” said ACS Energy Letters Editor-in-Chief Prashant Kamat. “As we all know, the lithium-ion battery has revolutionized our modern-day activities. From mobile phones to laptops and from electronic gadgets to electric cars, these storage batteries have become part of our everyday life. We at ACS Publications are excited to be part of this celebration.”

Whittingham laid the foundation of the lithium-ion battery while working at Exxon in the 1970s. During that time, the oil crisis in the United States was ongoing, and there was a strong drive to develop methods of energy storage and transport that did not rely on fossil fuels. Whittingham developed a 2V lithium-ion battery based on a titanium disulfide cathode and lithium metal anode. While a seminal contribution to the advancement of the lithium battery, adopting Whittingham’s system for everyday use would be limiting due to the high reactivity of lithium metal and risk of explosion.

In a recent paper (Generating Light from Darkness), published on Joule, Stanford University researchers Aaswath P. Raman, Wei Li, and Shanhui Fan are reporting the successful creation of a device that is able to generate electricity by exploiting the difference of temperature that can be established during the night between the surrounding air and the surface of the device that is cooling itself by emitting infrared radiations towards the night sky.

The possibility to generate electricity by exploiting thermal difference is not new, what is new here is the idea of creating a temperature difference by having part of the device radiating energy into the outer space.

Are consumers ready for meat grown in a lab?

Companies like Memphis Meats, Aleph Farms, Higher Steaks, Mosa Meat and Meatable are all trying to bring to supermarkets around the world meat made from cultivated animal cells, but the problem has always been the cost.

Now, Future Meat Technologies has raised $14 million in new financing to build its first pilot manufacturing facilities to bring the cost of production of a cell-made steak down to $10 per pound — or $4 if the meat is combined with plant-based meat substitutes.

A new solar-powered system can take the salt out of ocean water. The technology can supply water for 25,000 people per day.

Ultra-fast pulses from a powerful laser can create droplets of water out of thin air, according to a new study. With the right conditions and large enough droplets, the researchers say, the technique could be used to make rain on demand.

Rain forms when water condenses around tiny particles in the atmosphere. Most of the time, dust or pollen do the job, but humans have long attempted to speed the process by seeding clouds with chemicals like silver iodide. Those chemicals provide the so-called “condensation nuclei” that trigger the consolidation of water into raindrops.

If we want to colonize Mars, we’re going to need to figure out a way to feed ourselves there, and continuously sending food to the Red Planet isn’t a sustainable plan.

But now, a team of researchers thinks it’s figured out a way to produce enough food on Mars to feed a million people — and they say their plan to make Martian colonists self-sufficient would take just a hundred years to implement.

Moses West is a former Ranger. Four years ago he set out to change the world, one atmospheric water generator at a time. He created these to provide clean drinking water to communities in Flint, MI, The Bahamas and Puerto Rico. Get this, he doesn’t charge these residents one penny. So far, he’s created 12 of these AWGs. He currently has one of these generators planted in Flint. More of these machines are currently being manufactured in WI to transport to Flint in the near future. He found a few minutes to down with Spectrum News 1’s Michelle London.
