Researchers at Penn State have developed the world's first functioning computer built entirely from two-dimensional atom-thin materials, marking a significant step away from silicon-based electronics and paving the way for ultra-efficient, miniaturized devices.
Scientists have developed a razor-thin crystalline film semiconductor that allows electrons to move seven times faster than in traditional semiconductors, potentially revolutionizing electronic devices by improving efficiency and reducing energy waste. The film, made from ternary tetradymite and created using molecular beam epitaxy, could lead to advancements in wearable thermoelectric and spintronic devices.
Researchers from Ritsumeikan University and collaborators have developed a novel antiaromatic π-stacking system using NiII-coordinated norcorroles with aliphatic side chains, leading to the formation of highly conductive liquid crystals. This breakthrough could significantly advance the design of organic semiconductors and electronic devices.
Researchers have developed a novel 2D/3D/2D heterostructure that enhances the energy storage capability of ferroelectric capacitors. By controlling the relaxation time of ferroelectric materials using 2D materials, they achieved an energy density up to 19 times higher than commercially available capacitors, with an efficiency over 90%. This innovation paves the way for high-performance electronic devices, particularly in sectors requiring robust power management solutions, such as electric vehicles and infrastructure development.
UN agencies report that the global generation of electronic waste, or "e-waste," reached 62 million tons in 2022 and is projected to increase to 82 million tons by 2030, with recycling rates remaining low. The discarded devices include cellphones, electronic cars, TVs, laptops, and more, posing a significant environmental challenge.
Researchers at the University of Kansas' Ultrafast Laser Lab have observed the ballistic movement of electrons in graphene, a promising material for next-generation electronic devices. By using ultrafast lasers, the researchers were able to trace the movement of electrons in real-time, revealing that electrons in graphene can move ballistically, similar to cars on a freeway or ballistic missiles through the air. This discovery could lead to breakthroughs in governing electrons in semiconductors, potentially resulting in faster, more powerful, and more energy-efficient electronic devices.
Researchers from the University of California have developed a solid-state thermal transistor that uses an electric field to control the flow of heat in electronic devices. The transistor utilizes a thin film of molecules as a channel, and by applying an electric field, the thermal conductance of the film increases. The transistor requires less power compared to other dissipation methods, has a high thermal conductance ratio, and can be used in conjunction with other cooling techniques. While still in the early stages of development, the technology shows promise for enabling faster and more powerful processors.
The FBI has seized several electronic devices, including cellphones and an iPad, belonging to New York City Mayor Eric Adams as part of a federal investigation into his campaign's fundraising efforts and potential links to foreign powers. Adams voluntarily turned over the devices after being approached by federal officials. The seizure comes after a recent raid on a Brooklyn residence connected to a campaign fundraiser. Adams has hired a criminal defense firm and maintains his cooperation with the investigation. The investigation is examining whether the Adams campaign conspired with the Turkish government to receive donations from foreign sources.
The FBI seized New York City Mayor Eric Adams' iPhones and iPad as part of a corruption investigation into campaign fundraising. Adams' campaign attorney stated that an individual close to the mayor had acted improperly and that this behavior was reported to investigators. The mayor has not been accused of any wrongdoing and continues to cooperate with the investigation. The FBI raid on the home of Adams' chief campaign fundraiser raised questions about his involvement, and it is believed that information about someone else in the mayor's circle was on one of the seized devices. The FBI was likely looking for text messages, emails, and call records as evidence.
Scientists have developed hydrogels that can be controlled with electricity, allowing them to be easily connected to electronic devices. These hydrogels respond to low voltage and can stretch up to 300% when electricity is applied, making them useful for various applications in materials science and responsive materials.
Researchers at Penn State have developed a new electrical method to control the direction of electron flow in quantum materials that exhibit the quantum anomalous Hall (QAH) effect. By applying a five-millisecond current pulse, the internal magnetism of the material is impacted, causing the electrons to change directions. This method could have implications for the development of next-generation electronic devices and quantum computers, improving the efficiency of information transfer and storage in quantum technologies. The researchers are also exploring how to pause electrons on their route and replicate the QAH effect at higher temperatures.
Two upset siblings, aged 10 and 11, stole their mother's car in Florida after their electronic devices were confiscated. They drove about 200 miles before being pulled over by deputies. The children were reported missing, and their mother, who was doing her best to raise them, came to take custody of them without pressing charges.
Two children, aged 10 and 11, stole their mother's car in Florida after she took away their electronic devices as punishment. The siblings were pulled over by authorities over 200 miles away from their home. The children were reported missing and the stolen vehicle belonged to their mother. However, their mother did not want to pursue criminal charges, so the children were not jailed. The only charge they faced was a criminal traffic violation.
Sleep hygiene refers to creating and following healthy sleep habits and routines, as well as maintaining a conducive sleep environment. To improve sleep hygiene, establish a consistent sleep schedule, make your bedroom conducive to sleep by investing in a supportive mattress, pillow, and maintaining an optimal temperature, create a relaxing bedtime routine, avoid using electronic devices before bed, eat and drink sensibly throughout the day, and incorporate exercise into your daily routine.
Researchers from the University of California San Diego have developed a method to repurpose electronic devices, such as cell phones, into processors, aiming to tackle the growing problem of e-waste. With billions of mobile phones ending up in landfills each year, this innovative solution could help reduce toxic waste and promote recycling.
