Over the past decades, electronics engineers have created devices of various shapes and with increasingly sophisticated designs. This includes electronics that can be folded onto themselves, such as foldable phones, along with various other compressible devices.

Researchers at Ajou University and other institutes in South Korea recently introduced a new design for developing crumple-recoverable electronics, or in other words, electronics that can recover their original shape after being crumpled or compressed onto themselves to reduce their size. This design, outlined in a paper published in Nature Electronics, draws inspiration from the mechanism that allows butterflies to unfold their wings when leaving their cocoon.

“Nature is rich of different plants and animals, each of which survived by adapting and evolving in extreme environments,” Seungyong Han, co-author of the paper, told Tech Xplore. “Personally, I’ve always thought that by closely observing these phenomena, we can find clues to solve various problems in modern society. Also, by approaching this from an engineering perspective, I believed we could achieve results that may improve people’s daily lives.”

With the market for wearable electric devices growing rapidly, stretchable solar cells that can function under strain have received considerable attention as an energy source. To build such solar cells, it is necessary that their photoactive layer, which converts light into electricity, shows high electrical performance while possessing mechanical elasticity. However, satisfying both of these two requirements is challenging, making stretchable solar cells difficult to develop.

A KAIST research team from the Department of Chemical and Biomolecular Engineering (CBE) led by Professor Bumjoon Kim announced the development of a new conductive polymer material that achieved both high electrical performance and elasticity while introducing the world’s highest-performing stretchable organic solar cell.

Every legislative session is presented with too many bills and, in recent years, too slim of a majority to get the good ones to the Governor. But because we have so many new ideas, there are always some you might not expect, like legislation to ban weather modification.

To be clear, I’m not making fun of the bill or its sponsors. In a world where some folks can’t shut up about unnecessary “emissions” or pollutants in our atmosphere, this should play well on both sides of the aisle. New Hampshire House Bill 1,700 (HB1700).

The UK carrier said they had to ‘get creative’ to reach the islanders.

London-based carrier Openreach has deployed “world-first engineering” as part of its efforts to connect residents on a remote Scottish island.

Strain-induced crystallization can strengthen, toughen, and facilitate an elastocaloric effect in elastomers. The resulting crystallinity can be induced by mechanical stretching in common elastomers that are typically below 20%, with a stretchability plateau.

In a new report now published in Science Advances, Chase M. Hartquist and a team of scientists in mechanical engineering and materials sciences at MIT and Duke University in the U.S. used a class of elastomers formed by end-linking to achieve a percentage of strain-induced crystallinity.

The deswollen and end-linked star elastomer abbreviated as DELSE reached an ultrahigh stretchability to scale, beyond the saturated limit of common elastomers, to promote a high elastocaloric effect with an adiabatic temperature change.

A research team led by Professor Jong-min Choi of the Department of Energy Engineering has developed a technology that can significantly improve the efficiency of quantum dot photovoltaic cells by introducing organic solvent dispersible MXene.

The findings were published in Advanced Energy Materials (“Organic solvent dispersible MXene integrated colloidal quantum dot photovoltaics”).

Quantum computing is often hailed as the next frontier of technology, promising to solve some of the most complex and challenging problems in science, engineering, and business. But how close are we to achieving this quantum dream, and what are the limitations of this emerging field?

As IEEE Spectrum shares in its detailed report, some of the leading voices in quantum computing have recently expressed doubts and concerns about the technology’s current state and prospects. They argue that quantum computers are far from being ready for practical use and that their applications are more restricted than commonly assumed.

The Paulding Light, a perplexing glow in the Michigan sky, has fueled folklore with its eerie nightly appearances since the 1960s. What was once thought to be a ghostly signal has turned into a case study for scientific inquiry. A team of Michigan Tech students, led by Jeremy Bos, a PhD candidate in electrical engineering, undertook a methodical investigation to expose the truth behind the spectral luminance that intrigued both locals and visitors in Michigan’s Upper Peninsula.

Their rigorous scientific approach involved telescopes, spectrographs, and atmospheric modeling, which demystified the paranormal claims. By observing the phenomenon through a telescope, the researchers identified the lights as nothing more than the headlights and taillights of vehicles on a distant stretch of US Highway 45. This was further supported by spectral analysis, confirming the automotive origin of the lights. The team’s findings pointed to atmospheric conditions and the geography of the Paulding area, which caused the vehicle lights to refract and create the illusion of the unexplained Paulding Light.

Despite the logical explanations provided by these dedicated students, the Paulding Light’s allure remains undiminished. The legend continues to attract those drawn to the supernatural, demonstrating the human fascination with mystery over the mundane. The Paulding Light stands as a symbol of our enduring attraction to the unexplained, a reminder that sometimes, even when the truth is revealed, the legend never dies.
