Up until the 1948, the lemon-lime soda 7-Up contained lithium salts, a substance most commonly known for its medical qualities used in the treatment of major depressive disorders.

While the additive has long since been removed from 7-Up, the scientists from the YouTube channel Periodic Videos thought it would be interesting to drop a piece of lithium into the current day recipe for the soda.

Initially, the results were as expected: nothing special. But after a few more seconds, the solution began transforming from its clear, bubbly state to a dark, sludgy brown. Watch as Sir Martyn Poliakoff explains the unexpected phenomena.

The Bill & Melinda Gates Foundation has been fighting the good fight on many fronts over the years, including poverty, women’s equality, and of course, energy.

In their 2016 annual letter, the private foundation looked at the issue of access to energy. According to Bill Gates, 1.3 billion people – or 18 percent of the world’s population – live without electricity to light their homes.

Energy crisis

Many energy trouble areas exist in sub-Saharan Africa, where 7 out of 10 people live in the dark. The same problems exist in parts of Asia and India where more than 300 million people lack access to electricity.

There are still many parts of the world that have yet to reap the benefits of Thomas Edison’s incandescent light bulb.

But it’s not just about light. Energy allows better medical care through functioning hospitals, greater educational efforts through functioning schools, and even more food through the powering of agricultural devices.

Renewable energy revolution

Not only is the provision of energy to all people essential, but the research into finding a clean, efficient way to do so is also crucial. ECS members and scientists across the globe are currently making effort to combat climate change, which is consequentially poised to hit the world’s poor the hardest.

The word “renewable” often triggers thoughts of solar and wind in the realm of energy technology.

Two researchers from Virginia Tech are now trying to change that perception, focusing on maximizing the amount of electricity that can be generated from the wastewater we flush down the toilet.

They’re turning poo into power.

“Tracing the bacteria gave us a major piece of the puzzle to start generating electricity in a sustainable way,” said Xueyang Feng, co-author of the study. “This is a step toward the growing trend to make wastewater treatment centers self-sustaining in the energy they use.”

The saying goes: an apple a day keeps the doctor away; but in this case, an apple may be the answer to the next generation of energy storage technology.

ECS member Stefano Passerini of the Karlsruhe Institute of Technology is leading a study to extract carbon-based materials for sodium-ion batteries from organic apple waste.

Developing batteries from waste

This new development could help reduce the costs of future energy storage systems by applying a cheap material with excellent electrochemical properties to the already promising field of sodium-ion batteries.

Many researchers are currently looking to sodium-ion batteries as the next generation of energy storage, with the ability to outpace the conventional lithium-ion battery.

The future of sodium-ion batteries

Interest in sodium-ion batteries dates back to the 1980s, but discoveries haven’t taken off until recently. Researchers are now finding way to combat low energy densities and short life cycles through using novel materials such as apples.

Tesla is most commonly known for its novel innovations in automobile technology, research into battery technology, and even the company’s dedication to open source knowledge. Now, the company is shifting gears to create a product for all the tiny Elon Musk fans out there.

Tesla, in collaboration with Radio Flyer, has recently produced line of electric vehicles for kids.

True to Tesla vehicles, the kid car is essentially a scale model of Tesla’s popular electric sedan.

Metasensor’s Sensor-1 is a personal security system for your portable goods.

Home security systems are great for protecting valuables inside your home and stopping attempted burglaries, but those systems aren’t very practical when you travel with your precious, portable property.

Metasensor has developed its new Sensor-1, which acts as a portable security system – changing the way we protect our belongings and track objects in general.

This from Popular Science:

Sensor-1 is a small, octagonal disk that contains an accelerometer, a gyroscopic stabilizer, and a magnetometer, which work together to track the orientation of the device it’s attached to in three dimensions. They alert Sensor-1 if the object has been moved, and how. It also has three LED lights, a small siren, and Bluetooth connectivity.

Battery applications range from powering electronic devices to storing energy harvested from renewable sources, but batteries have a range of applications beyond the obvious. Now, researchers from the University of Illinois at Urbana-Champaign are taking existing battery technology and applying it to efforts in water desalination.

The researchers have published the open access article in the Journal of The Electrochemical Society.

“We are developing a device that will use the materials in batteries to take salt out of water with the smallest amount of energy that we can,” said Kyle Smith, ECS member and assistant professor at the University of Illinois at Urbana-Champaign. “One thing I’m excited about is that by publishing this paper, we’re introducing a new type of device to the battery community and to the desalination community.”

Water desalination technologies have flourished as water needs have grown globally. This could be linked to growing populations or drought. However, because of technical hurdles, wide-spread implementation of these technologies has been difficult. However, the new technologies developed could combat that issue by using electricity to draw charged salt ions out of the water.

A radical new development from Cornell University has the potential to change the superconducting community. For the first time, researchers have developed a self-assembling, porous, 3D gyroidal superconductor, which may have completely new properties.

This from Futurity:

The gyroid is a complex cubic structure based on a surface that divides space into two separate volumes that are interpenetrating and contain various spirals. Pores and the superconducting material have structural dimensions of only around 10 nanometers, which could lead to entirely novel property profiles of superconductors.

Read the full article.

Benefits of superconductors

Because superconductors offer no resistance to electrical current and can repel magnetic fields, they hold immense potential for future applications. While we depend on electricity to power a majority of our devices, researchers are always looking for a way to cut heat resistance. Heat resistance not only causes the deterioration and breakdown of appliances, it also leads to wasted energy.

(MORE: Read “Superconductors and the Future.“)

Superconductors, however, offer no resistance to electrical current. However, this is only at extremely low temperatures. The new research out of Cornell University challenges that traditional notion.

Development could ‘revolutionize everything’

“There’s this effort in research to get superconducting at higher temperatures, so that you don’t have to cool anymore,” said Ulrich Wiesner, leader of the research group. “That would revolutionize everything. There’s a huge impetus to get that.”
