Lithium batteries are what allow electric vehicles to travel several hundred miles on one charge. Their capacity for energy storage is well known, but so is their tendency to occasionally catch on fire—an occurrence known to battery researchers as “thermal runaway.” These fires occur most frequently when the batteries overheat or cycle rapidly. With more and more electric vehicles on the road each year, battery technology needs to adapt to reduce the likelihood of these dangerous and catastrophic fires.

Researchers from the University of Illinois at Chicago College of Engineering report that graphene—wonder material of the 21st century—may take the oxygen out of lithium battery fires. They report their findings in the journal Advanced Functional Materials.

The reasons lithium batteries catch fire include rapid cycling or charging and discharging, and high temperatures in the battery. These conditions can cause the cathode inside the battery—which in the case of most lithium batteries is a lithium-containing oxide, usually lithium cobalt oxide—to decompose and release oxygen. If the oxygen combines with other flammable products given off through decomposition of the electrolyte under high enough heat, spontaneous combustion can occur.

Trade Secretary Ramon Lopez said the DTI would soon launch an initiative to train the country’s IT and engineering graduates to create AI solutions for the global marketplace.

Instead of fearing artificial intelligence (AI), a supposed threat to the country’s thriving business process outsourcing (BPO) industry, the Philippines can position itself as a global AI hub, Trade Secretary Ramon Lopez said.

In a recent chance interview, Lopez said the Department of Trade and Industry would soon launch an initiative to train the country’s IT and engineering graduates to create AI solutions for the global marketplace.

Electrochemical energy systems—processes by which electrical energy is converted to chemical energy—are at the heart of establishing more efficient generation and storage of intermittent energy from renewable sources in fuel cells and batteries.

The powerhouse substances known as catalysts, which are used to accelerate chemical reactions, are key players in these systems. The size and efficiency of fuel cells, for example, could greatly benefit from using high-performance catalysts.

Producing better catalysts is easier said than done, however. A catalyst’s usefulness is partially based on the amount and quality of its active sites, due to the sites’ specific geometry and electronic properties. Engineering these sites can be an arduous, inefficient process.

Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Reza Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in Physical Review B demonstrating it’s possible to silence noise using an open, ringlike structure, created to mathematically perfect specifications, for cutting out sounds while maintaining airflow.

The U.S. Missile Defense Agency is looking for information on a 1,000 kW-class electrically-pumped laser for defending the United States, its deployed forces, allies, and friends against all ranges of enemy ballistic missiles in all phases of flight.

The post on the federal business opportunities website is asking industry for information on a capability to demonstrate a 1,000 kW-class electrically-pumped laser in the 2025–26 timeframe.

Missile Defense Agency does not provide a specific platform or strategic mission at this time. The proposed ground demonstrator laser system would be designed to have technology maturation and lightweight engineering paths to potential future platforms.

Hot off the press…

Barnes & Noble Press releases a new non-fiction book The Syntellect Hypothesis: Five Paradigms of the Mind’s Evolution by Alex M. Vikoulov as Hardcover (Press Release, San Francisco, CA, USA, March 22, 2019 11.00 AM PST)

Named “The Book of the Year” by futurists and academics alike, “# 1 Hot New Release” in Amazon charts in Physics of Time, Phenomenology, and Phenomenological Philosophy, the book has now been released by Barnes & Noble Press as hardcover in addition to ebook and paperback released earlier this year. In one volume, the author covers it all: from quantum physics to your experiential reality, from the Big Bang to the Omega Point, from the ‘flow state’ to psychedelics, from ‘Lucy’ to the looming AI Singularity, from natural algorithms to the operating system of your mind, from geo-engineering to nanotechnology, from anti-aging to immortality technologies, from oligopoly capitalism to Star-Trekonomics, from the Matrix to Universal Mind, from Homo sapiens to Holo syntellectus.

Climate change is a sprawling, complex problem. But there is an astonishingly simple way to make a difference: plant more trees. Trees scrub pollution from the air, reduce erosion, improve water quality, provide homes for animals and insects, and enhance our lives in countless other ways.

It turns out that ecosystem restoration is also an emerging business opportunity. A new report from the World Resources Institute and the Nature Conservancy says governments around the world have committed to reviving nearly 400 million acres of wilderness — an area larger than South Africa. As countries push to regrow forests, startups are dreaming up new, faster ways to plant trees. For some innovators, like NASA veteran Dr. Lauren Fletcher, that means using drones.

Fletcher said his conversion from stargazer to eco-warrior was driven by his worry about climate change, which has been dramatically worsened by deforestation. To tackle the problem, he created BioCarbon Engineering, which he describes as an ecosystem restoration company. Working with colleagues, he came up with a 30-pound unmanned aerial vehicle nicknamed “Robin.” It can fly over the most rugged landscapes on earth, planting trees in precise locations at the rate of 120 per minute.

When Genevieve posted about optical tweezers, I noticed the similarity with acoustic tweezers, so I needed to post this article as well, so as to add to hers.

A new algorithm recently helped scientists levitate multiple objects using sound waves in very strategic positions. It marked the first time that sound helped capture numerous objects in various positions. The findings were recently published in the journal Proceedings of the National Academy of Science. It was funded by the Engineering and Physical Sciences Research Council (EPSRC) in the United Kingdom.
