Since the advent of quantum mechanics, the field of physics has been divided into two distinct areas: classical physics and quantum physics. Classical physics deals with the movements of everyday objects in the macroscopic world, while quantum physics explains the strange behaviors of tiny elementary particles in the microscopic world.

Many solids and liquids are made up of particles that interact with each other at close distances, leading to the creation of “quasiparticles.” Quasiparticles are stable excitations that act as weakly interacting particles. The concept of quasiparticles was introduced in 1941 by Soviet physicist Lev Landau and has since become a crucial tool in the study of quantum matter. Some well-known examples of quasiparticles include Bogoliubov quasiparticles in superconductivity, excitons in semiconductors.

Researchers are coming to understand that the best performing materials in sustainable energy applications, such as converting sunlight or waste heat to electricity, often use collective fluctuations of clusters of atoms within a much larger structure. This process is often referred to as “dynamic disorder.”

Understanding dynamic disorder in materials could lead to more energy-efficient thermoelectric devices, such as solid-state refrigerators and heat pumps, and also to better recovery of useful energy from waste heat, such as car exhausts and power station exhausts, by converting it directly to electricity. A thermoelectric device was able to take heat from radioactive plutonium and convert it to electricity to power the Mars Rover when there was not enough sunlight.

“Now is the moment for a rigorous portrait of Elon Musk.”

Alex Gibney, an award-winning filmmaker, is working on a new documentary about Elon Musk. The movie “Musk” aims to be “a definitive and unvarnished investigation” of the multibillionaire CEO of SpaceX, Tesla, and Twitter. The project has been in the works for months.

Other documentaries by Gibney have explored topics such as Steve Jobs, Enron, WikiLeaks, Elizabeth Holmes, Scientology, and more.

Recycling spent lithium-ion batteries plays a significant role in alleviating the shorting of raw materials and environmental problems. However, recycled materials are deemed inferior to commercial materials, preventing the industry from adopting recycled materials in new batteries.

Now, researchers at Worcester Polytechnic Institute (WPI) in Massachusetts have demonstrated that the recycled materials from used lithium-ion batteries can outperform new commercial materials, making the recycled materials a potentially green and profitable resource for battery producers. Led by Yan Wang, professor in the Department of Mechanical and Materials Engineering, the team of researchers used physical tests, imaging, and computer simulations to compare new cathode materials recovered from old electric vehicle batteries through a recycling process, which is being commercialized by Battery Resourcers Inc. of Worcester.

The technology involved shredding batteries and removing the steel cases, aluminum and copper wires, plastics, and pouch materials for recycling. Researchers then dissolved the metals from those battery bits in an acidic solution. They by tweaking the solution’s pH, the team removed impurities such as iron and copper and recovered over 90% of three key metals – nickel, manganese, and cobalt. The recovered metals formed the basis for the team’s cathode material.

The soot produced by unburnt hydrocarbon flames is the second largest contributor to global warming, while also harming human health. Researchers have developed state-of-the-art, high-speed imaging techniques to study turbulent flames, yet they are limited to an imaging rate of million-frames-per-second. Physicists are therefore keen to obtain a complete picture of flame-laser interactions via single-pulse imaging.

In a new report published in Light: Science & Applications, Yogeshwar Nath Mishra and a research team at the Caltech Optical Imaging Laboratory, the NASA Jet propulsion lab, department of physics, and the Institute of Engineering Thermodynamics in the U.S., and Germany, used single-shot laser-sheet comprised ultrafast photography per billion frames per second, for the first time, to observe the dynamics of laser-flames.

Tesla held Investor Day 2023 this week and announced the construction of a new plant in the Mexican state of Nuevo Leon. The new facility will be Tesla’s largest production facility.

Here’s What We Know

Elon Musk’s company will invest $5 billion to build the Mexican plant and create 5,000–6,000 jobs. Over time, however, the amount of investment and the number of jobs will double.

MANUFACTURA’s eggshell project transforms organic waste into a sustainable building material made from 3D printed eggshells.

As fusion developers around the world race to commercialize fusion energy, TAE Technologies has pioneered the pursuit of the cleanest and most economical path to providing electricity with hydrogen-boron (also known as p-B¹¹ or p¹¹ B), an abundant, environmentally sound fuel. Today the company is announcing, in collaboration with Japan’s National Institute for Fusion Science (NIFS), a noteworthy research advancement: the first-ever hydrogen-boron fusion experiments in a magnetically confined fusion plasma.

In a paper published by Nature Communications, scientists explain the outcome of the nuclear fusion reaction of hydrogen-boron in an experiment in NIFS’ Large Helical Device (LHD). This paper describes the experimental work of producing the conditions necessary for hydrogen-boron fusion in the LHD plasma and TAE’s development of a detector to make measurements of the hydrogen-boron reaction products: helium nuclei, known as alpha particles.

The finding reflects years of collaborative international scientific fusion research, and represents a milestone in TAE’s mission to develop commercial fusion power with hydrogen-boron, the cleanest, most cost-competitive, and most sustainable fuel cycle for fusion.

The company also showcased other executives, which could alleviate concern that Musk has been too distracted by his other business ventures. They also talked about “meat and potato” topics like cutting costs, improving margins, and EV-charging infrastructure.

The keys to winning the EV race will come down to product appeal, software or user interface, controlling cost, and consistent execution, he said.

“And Tesla right now is one generation ahead of the other automakers,” Fields said, though rivals like Ford and Hyundai are making a lot of progress. “Tesla still has the leg-up on the competition, and I think they demonstrated that yesterday.”
