Thermoelectric conversion devices offer a promising route for sustainable heat-to-energy conversion. They are particularly attractive for recovering energy from waste heat, such as that produced by conventional fossil fuel-based engines, improving their overall energy efficiency.This […]
Despite the prevalence of synthetic materials across different industries and scientific fields, most are developed to serve a limited set of functions. To address this inflexibility, researchers at Penn State, led by Hongtao Sun, assistant […]
Seating furniture is frequently not designed for long-term use or simple assembly and disassembly and has a tendency to break after just one move. This does not apply to the benches, chairs, and stools that […]
Additive manufacturing has revolutionized manufacturing by enabling customized, cost-effective products with minimal waste. However, with the majority of 3D printers operating on open-loop systems, they are notoriously prone to failure. Minor changes, like adjustments to […]
Consider the marvelous physics of the human knee. The largest hinge joint in the body, it has two rounded bones held together by ligaments that not only swing like a door, but also roll and […]
Chemical, biological, radiological, nuclear and explosive substances (CBRNE substances for short) can pose a threat to the public and to emergency services. For example, in 2023, a cesium capsule measuring just a few millimeters in […]
Electromagnetic pulses (EMPs)—high-energy-density and ultra-wideband beams of electromagnetic radiation—are generated from sources such as nuclear explosions, high-power electromagnetic pulse devices, and intentional electromagnetic interference. These pulses can infiltrate electronic equipment to significantly incapacitate civilian and […]
The UK government’s proposed reforms to policing in England and Wales signal an increase in the use of facial recognition technology. The number of live facial recognition vans is set to rise from ten to […]
Researchers at Monash University and the University of Melbourne have developed a quantum-inspired approach to optical wireless communication that promises to make 6G networks faster, more reliable and energy-efficient. As the world moves toward 6G, […]
Snapchat has blocked 415,000 accounts under Australia’s social media ban for under-16s, the company said Monday, but warned some youngsters may be bypassing age verification technology.This article is brought to you by this site.
