University of Wisconsin–Madison engineers have used a spray coating technology to produce a new workhorse material that can withstand the harsh conditions inside a fusion reactor.

The advance, detailed in a paper published recently in the journal Physica Scripta, could enable more efficient compact fusion reactors that are easier to repair and maintain.

“The fusion community is urgently looking for new manufacturing approaches to economically produce large plasma-facing components in fusion reactors,” says Mykola Ialovega, a postdoctoral researcher in and engineering physics at UW–Madison and lead author on the paper. “Our technology shows considerable improvements over current approaches. With this research, we are the first to demonstrate the benefits of using cold spray coating technology for fusion applications.”

Johns Hopkins researchers have identified minuscule particles that supercharge therapeutic cancer vaccines, which train the immune system to attack tumors. These new lipid nanoparticles—tiny structures made of fat—not only stimulate a two-pronged immune system response that enhances the body’s ability to fight cancer but also make vaccines more effective in targeting tumors.

“This research marks a pivotal turning point in our understanding of how can be harnessed to optimize anticancer immunity,” said Hai-Quan Mao, director of Johns Hopkins’ Institute for NanoBioTechnology and professor in the Whiting School of Engineering’s Department of Materials Science and Engineering. “Our findings unlock new avenues for enhancing the efficacy of RNA-based treatments for and infectious diseases.”

The team’s results appear in Nature Biomedical Engineering.

Weeks after introducing a potentially game-changing “Uni-wheel” drive system for EVs, Hyundai and Kia are showing off another next-generation technology to keep EV drivers safer during inclement weather. Today, Kia and Hyundai introduced a new snow chain-integrated tire that utilizes shape memory alloy modules inside the wheel. See how this incredible new tech works in the video below.

As EVs continue to saturate the global automotive market, their respective technologies are evolving to benefit consumers. Now more than ever, these electric vehicles drive farther, charge faster, and come equipped with exciting new technologies like vehicle-to-load (V2L) capabilities and Plug & Charge.

Hyundai Motor Group has been one of the early proponents of such technologies, featuring them in EVs atop its E-GMP platform. In fact, Hyundai and Kia especially have rolled out some exciting technologies throughout the electric mobility segment and allocated considerable funds to R&D to explore new engineering breakthroughs.

Engelbart grew up on a small farm in Southeast Portland where his father operated a radio store.

He graduated from Franklin High School in 1942 and enrolled at Oregon State College, now called Oregon State University, to study electrical engineering.

When World War II interrupted his studies, he spent two years working as a Navy radio and radar technician in the Philippines.

In an indication of growing interest in the holy grail of geothermal energy—tapping into the superhot rock miles below our feet—18 papers on the topic were presented over multiple sessions at a recent major conference on the overall geothermal industry.

“By driving down costs and making large-scale geothermal power available nearly anywhere, Superhot Rock energy has the potential to disrupt and revolutionize the energy system.” That’s according to a description of the sessions on Technological, Engineering, and Geological Advances in Superhot Geothermal presented at the 2023 Geothermal Rising Conference held over four days in October.

“For me, a pretty big highlight of Geothermal Rising 2023 was the increased focus on superhot rock geothermal through multiple presentations from around the world,” says Matt Houde, co-founder and project manager at Quaise Energy.

EPFL researchers have developed a hybrid device that significantly improves existing, ubiquitous laser technology.

The team at EPFL’s Photonic Systems Laboratory (PHOSL) has developed a chip-scale laser source that enhances the performance of semiconductor lasers while enabling the generation of shorter wavelengths. This pioneering work, led by Professor Camille Brès and postdoctoral researcher Marco Clementi from EPFL’s School of Engineering represents a significant advance in the field of photonics, with implications for telecommunications, metrology, and other high-precision applications.

Innovative integration for improved coherence and visibility.

Self-propelled nanoparticles could potentially advance drug delivery and lab-on-a-chip systems — but they are prone to go rogue with random, directionless movements. Now, an international team of researchers has developed an approach to rein in the synthetic particles.

Led by Igor Aronson, the Dorothy Foehr Huck and J. Lloyd Huck Chair Professor of Biomedical Engineering, Chemistry and Mathematics at Penn State, the team redesigned the nanoparticles into a propeller shape to better control their movements and increase their functionality. They published their results in the journal Small (“Multifunctional Chiral Chemically-Powered Micropropellers for Cargo Transport and Manipulation”).

A propeller-shaped nanoparticle spins counterclockwise, triggered by a chemical reaction with hydrogen peroxide, followed by an upward movement, triggered by a magnetic field. The optimized shape of these particles allows researchers to better control the nanoparticles’ movements and to pick up and move cargo particles. (Video: Active Biomaterials Lab)
