P-n diodes are two-terminal devices that consist of two types of semiconductor materials (i.e., a p-type and an n-type material) joined together. These components allow electric current to only move in one direction, which is central to the functioning of many electronic circuits.... Read more

Imagine traveling in a foreign country, reaching for a window you've never seen before, and instead of struggling to open it, you feel your own muscles gently guide you through the motion, as if an invisible teacher was there, lending their know-how. Now picture that same sensation helping you twist... Read more

Muscles are remarkably effective systems for generating controlled force, and engineers developing hardware for robots or prosthetics have long struggled to create analogs that can approach their unique combination of strength, rapid response, scalability, and control. But now, researchers at the MIT Media Lab and Politecnico di Bari in Italy... Read more

Researchers have developed a simple and eco-friendly way to use a laser to turn natural leather into flexible and wearable energy devices. The new approach could lay the groundwork for more sustainable wearable electronics. In a paper in Optics Letters, the researchers demonstrate the new technique by creating microsupercapacitors on...

The delicate butterfly served as the inspiration for a new lightweight lattice structure that also boasts enhanced mechanical strength, impact resistance, and energy absorption capability through advanced structural design. A collaborative research team from Tohoku University and the Wuhan University of Technology developed this strong yet light-as-a-butterfly material with the... Read more

UNSW researchers have redesigned hydrogen fuel cells to solve a critical flaw, bringing clean energy for aviation, heavy transport and beyond closer to reality. Hydrogen fuel cells, using locally produced green hydrogen as the only fuel, have long been viewed as the ultimate clean energy source, but their commercialization has... Read more

A breakthrough technology has emerged to fundamentally solve the camera protrusion/thickness issue, which has been a persistent limitation as smart devices become thinner. A KAIST research team has developed an ultra-thin camera that achieves a wide 140-degree field of view (FOV) without any lens protrusion. This technology is expected to... Read more

In some settings and when completing some collaborative tasks, humans are required to coordinate their movements or actions with those of others. A clear example of this is musical performance, particularly instances in which two or more musicians play their instruments together.... Read more

Researchers have developed a solar-powered reactor to break down hard-to-recycle forms of plastic waste—such as drink bottles, nylon textiles and polyurethane foams—using acid recovered from old car batteries, and converting it into clean hydrogen fuel and valuable industrial chemicals. The results are reported in the journal Joule.... Read more

Electrons have three intrinsic properties: spin, charge and orbital angular momentum. Researchers have long studied how to use spin to more efficiently create an electrical current. But the field of orbitronics—which is based upon using an electron's orbital angular momentum, rather than its spin, to create a current flow—remains relatively... Read more

A major problem with quantum computers is memory, as the information they contain can be quickly lost. Quantum computers are not yet fully reliable—they are far too unstable. However, all around the world, people are trying to improve them—some of whom are based in Norway.... Read more

A research team at Tohoku University and Future University Hakodate has demonstrated that living biological neurons can be trained to perform a supervised temporal pattern learning task previously carried out by artificial systems. By integrating cultured neuronal networks into a machine learning framework, the team showed that these biological systems... Read more

While technology has made the world "smaller," it has also pulled individuals apart, thanks to mobile phones and other devices that command our attention. Cornell University researchers are using technology, in the form of a mirror-equipped robot, to help bring people together. Members of the Architectural Robotics Lab, led by... Read more

The effectiveness of air disinfection devices may now be measured in minutes, rather than hours, with a new technique from University of Michigan Engineering. This is important for researchers developing better antiviral air purifiers, helping to mitigate outbreaks of viral respiratory diseases and prepare for the next pandemic.... Read more

Imagine a paint that changes color depending on how hard its surface is hit. It could be used on football helmets to monitor concussion-level impacts, to record the handling history of shipped packages, or placed on insoles to analyze an orthopedic patient's gait.... Read more
