Wireless device makes clean fuel from sunlight, CO2 and water

“Researchers have developed a standalone device that converts sunlight, carbon dioxide and water into a carbon-neutral fuel, without requiring any additional components or electricity. We hope this technology will pave the way toward sustainable and practical solar fuel production Erwin …

Coffee stains inspire optimal printing technique for electronics

“Using an alcohol mixture, researchers modified how ink droplets dry, enabling cheap industrial-scale printing of electronic devices at unprecedented scales. Have you ever spilled your coffee on your desk? You may then have observed one of the most puzzling phenomena …

New insights into lithium-ion battery failure mechanism

“Researchers have identified a potential new degradation mechanism for electric vehicle batteries – a key step to designing effective methods to improve battery lifespan. The researchers, from the Universities of Cambridge and Liverpool, and the Diamond Light Source, have identified one …

‘Quantum negativity’ can power ultra-precise measurements

“Scientists have found that a physical property called ‘quantum negativity’ can be used to take more precise measurements of everything from molecular distances to gravitational waves. The researchers, from the University of Cambridge, Harvard and MIT, have shown that quantum …

Enigma code-breaking machine rebuilt at Cambridge

“Cambridge Engineering alumnus Hal Evans has built a fully-functioning replica of a 1930s Polish cyclometer – an electromechanical cryptologic device that was designed to assist in the decryption of German Enigma ciphertext. The replica currently resides in King’s College, Cambridge …

AI techniques used to improve battery health and safety

“Researchers have designed a machine learning method that can predict battery health with 10x higher accuracy than current industry standard, which could aid in the development of safer and more reliable batteries for electric vehicles and consumer electronics. The researchers …

Quantum state of single electrons controlled by ‘surfing’ on sound waves

“Researchers have successfully used sound waves to control quantum information in a single electron, a significant step towards efficient, robust quantum computers made from semiconductors. The international team, including researchers from the University of Cambridge, sent high-frequency sound waves across …

Driverless cars working together can speed up traffic by 35 percent

“A fleet of driverless cars working together to keep traffic moving smoothly can improve overall traffic flow by at least 35 percent, researchers have shown. The researchers, from the University of Cambridge, programmed a small fleet of miniature robotic cars …

A new spin on organic semiconductors

“Researchers have found that certain organic semiconducting materials can transport spin faster than they conduct charge, a phenomenon which could eventually power faster, more energy-efficient computers. Organic semiconductors have not been realistic candidates for spintronics so far because it was …

Magnetic graphene switches between insulator and conductor

“Researchers have found that certain ultra-thin magnetic materials can switch from insulator to conductor under high pressure, a phenomenon that could be used in the development of next-generation electronics and memory storage devices. The international team of researchers, led by …
