An important step towards super-efficient devices
Many of the machines we use today, such as microwave ovens, smartphones, speakers, smart watches, work using resonators that amplify different waves (ex., sound waves, electromagnetic waves, etc).
However, the currently used resonators come with a big limitation. They continuously lose energy and need a constant power supply to remain active. Bound State in the Continuum (BIC) and Bound Band in the Continuum (BBIC) can change this.
With BIC inside resonators, a system can store energy without losing it, which could help in making more efficient devices that don’t need constant energy input. With BBIC, when multiple systems are connected, the trapped waves can still move through the system without losing energy. This could lead to devices that work longer and more efficiently.
The Harrisburg Bureau of Fire was called to the residence and, while they worked to put out the fire, police evacuated Shapiro and his family from the residence safely, Shapiro said.
“Thank God no one was injured and the fire was extinguished,” Shapiro said in a statement.
On Sunday, fire damage was visible on the residence's south side, primarily to a large room often used for entertaining crowds and art displays. There was still a police presence early Sunday afternoon as yellow tape cordoned off an alleyway and an officer led a dog outside a iron security fence.
State police are leading the investigation. The agency offered a reward of up to $10,000 for information leading to an arrest and conviction.
The research will also experimentally assess the low and medium ionization stages of tungsten in the unresolved transition array (UTA) and quasi-continuum regions.
Tungsten-based materials considered promising plasma-facing materials
Multiple studies have also claimed that tungsten-based materials are considered to be one of the most promising plasma-facing materials, but there are still many problems in practical application.
Previously, researchers have stressed that plasma-facing materials are subjected to the multi-field coupling effect of thermal shock and multiple radiations, which requires tungsten-based materials to have not only good mechanical properties but also a certain resistance to irradiation.
Casap, in custody at the Waukesha County jail on a $1 million bond, is due in court next month to enter a plea. County prosecutors have offered a glimpse of the federal allegations, which were outlined in an FBI warrant unsealed Friday.
Federal authorities accuse Casap of planning his parents' murders, buying a drone and explosives, and sharing his plans with others, including a Russian speaker. His intentions are detailed in a three-page antisemitic manifesto praising Adolf Hitler. The warrant filed at the federal court in Milwaukee also contains excerpts of communications on TikTok and the Telegram messenger app.
Until now, it’s been considered a theoretical concept that could never occur in reality. However, for the first time, a team of Korean researchers has successfully realized BIC in a particle.
They performed an interesting experiment during which they trapped mechanical waves inside a single resonator. Here’s how they achieved this nearly impossible feat.
On Sunday, however, senior White House trade adviser Peter Navarro told NBC's "Meet the Press" they were "not exclusions," adding that the Trump administration could still impose tariffs on computer chips, according to the report.
Likewise, Commerce Secretary Howard Lutnick told ABC on Sunday that Trump could announce new tariffs on semiconductors "in the next month or two."
The assertions made by Navarro and Lutnick came the same day that China reacted to the exemptions, calling them a "small step by U.S. to correct its wrong practice of unilateral 'reciprocal tariffs.'" Trump on Wednesday increased tariffs on Chinese imports effectively to 145%.
Wedbush Securities analyst Dan Ives said in a note to investors Sunday that "the mass confusion created by this constant news flow out of the White House is dizzying for the industry and investors and creating massive uncertainty and chaos for companies trying to plan their supply chain, inventory and demand," the Times reported.
Tušek and his team are collaborating with a tech company from Ireland, as well as universities in Germany and Italy, to develop an advanced air conditioner based on the technology. The partnership has been named SMACool.
Nickel-titanium alloy can ensure cooling while remaining solid
Tušek notes that there are currently around two billion air conditioning units worldwide, and the IEA expects this number to nearly triple by 2050. This rapid growth, coupled with the fact that many air conditioning units are environmentally harmful, could contribute to a significant environmental crisis.
Cooling relies on the fundamental chemistry of phase changes, where matter shifts between different states—solid, liquid, or gas. In traditional cooling systems, the process of transforming from liquid to gas and back again drives the cooling cycle. However, certain materials, like the nickel-titanium alloy nitinol, can undergo a phase change while remaining in a solid state.
Published in the journal Energy & Environmental Science, the research reveals that in scaled-up applications, perovskite solar mini-modules with aperture areas of 25 and 100 cm2 demonstrated PCEs of 23.22% and 22.14%, respectively.
“The elevated glass transition temperature and robustly sequestered Li+ ions endow the devices with resilience against damp-heat conditions (85 °C/85% RH) for 1000 hours. Our findings signify a crucial leap towards commercialization by addressing thermal stability issues,” said researchers in the study.
The resulting cell produced a power conversion efficiency (PCE) of 25.56%—the highest among tBP-free solar cells.
The study authors examined this process in great detail using numerical simulations and some experiments and noticed a type of capillary instability in action. They found that the breakdown happened in a way similar to the Plateau–Rayleigh instability of classical liquids.
“While the Plateau–Rayleigh instability is well-known in classical liquids and has also been observed in superfluid helium, it has never before been seen in atomic gases,” Chiara Fort, one of the study authors and a physicist at the University of Florence, said.
The study authors claim that their measurements not only deepen the understanding of this unusual liquid phase but also show the potential for creating quantum droplet arrays, which could be useful in future technologies such as hi-tech quantum sensors and simulators.
“These busbars can be easily assembled and disassembled with standard screwed fasteners, and their flexible formats have been refined to simplify assembly operations and withstand potential vibrations in the vehicle’s battery pack,” highlighted the researchers.
Real-time smart energy monitoring
The technological advancements extend to the battery’s internal management. The Battery Management System (BMS) incorporates wireless communication and real-time smart energy monitoring, which reduces weight, cost, and complexity.
An intelligent Smart Cell Manager (iSCM) provides localized cell monitoring and Bluetooth communication with the BMS and drastically reduces wiring lengths.
Furthermore, the project integrates advanced recovery strategies to reclaim high-purity graphite, lithium, nickel, manganese, and cobalt from used cells, adhering to European regulations on battery sustainability.
“By integrating eco-design principles such as modularity, second-life applications, and materials with a high percentage of recycled content, MARBEL has extended battery usage while maintaining material value, effectively reducing waste and advancing both sustainability and economic viability,” explained Violeta Vargas, a researcher at Eurecat’s Waste, Energy, and Environmental Impact Unit.
The new cell’s efficiency is impressive but somewhat lower than other record tandem cells developed in recent times. One example is that of the solar cell by King Abdullah University of Science and Technology (KAUST) which reported 33.2% efficiency in April 2023.
China’s JinkoSolar also produced a 33.85% efficient perovskite tandem solar in January this year. However, the new tandem cell stands out not necessarily for its efficiency but for its novel and defect-reduced manufacturing process.
“I firmly believe in the power of collaboration, as many of today’s challenges are too complex for any individual to solve,” noted Yeo. “Therefore, I would like to express my gratitude to all the researchers in my group and the amazing collaborators who made this work possible. I will continue collaborating with the team to enhance BCI technology for rehabilitation and prosthetics,” he said.
Sensor classified neural signals with over 96% accuracy
The sensor developed by Georgia Tech uses extremely small microneedles which are imperceptible to the user. These sensors are also wireless and flexible, removing the need for conductive gel to work.
This combination of factors lets the sensor stay in place all day, even if the wearer walks, runs, or performs other daily tasks. Because of this, the sensor can get closer to brain signals and collect cleaner, more accurate data.
When tested, the new sensor successfully recorded and classified neural signals indicating the objects the user focused on in the environment with 96.4% accuracy. Wearers could also browse through phone logs and accept augmented reality video calls completely hands free because the sensor was picking up visual stimuli.
