Imagine a battery that stores more power, lasts longer, and remains safe even under stress. Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Chicago have discovered how to boost the energy density and cycle life of the power cells that form the core...

Numbers are the language of science—yet in research articles, they are often buried within the text and difficult to analyze. Researchers at Jülich have developed an AI system that automatically identifies these numbers, categorizes them, and converts them into structured data. The Quinex framework thus eliminates the need for time-consuming... Read more

A tightly packed ball of office staples can be surprisingly strong. Try to pull it apart and the tangled metal resists like a solid object. But with the right movement or vibration, that same bundle can quickly fall back into loose pieces. A team of engineers and materials scientists in... Read more

Recent progress in advanced energy manufacturing has opened a new path for lithium battery design. A joint research team led by Associate Professor Eric Jianfeng Cheng of Tohoku University has published a review in Materials Science and Engineering: R: Reports, that highlights the potential, the pitfalls, and different perspectives of...

When we think of materials, we usually think of substances like metal, concrete, glass or rubber. What these examples have in common is that they are inactive: when pushed, pulled, shifted or sheared they may move or deform, but only by using the energy that is provided from the outside...

The same wireless technology that can track your cat or locate an item in a warehouse can also monitor your breathing. Researchers at Chalmers University of Technology, Sahlgrenska University Hospital and the University of Gothenburg, Sweden, now present a completely new method for measuring breathing movements in patients with impaired...

Northwestern University engineers printed artificial neurons that don't just imitate the brain—they talk to it. In a new study, the Northwestern team developed flexible, low-cost devices that generate electrical signals realistic enough to activate living brain cells. When tested on slices of tissue from mouse brains, the artificial neurons successfully... Read more

In a recently published paper in Science Advances, a team led by Rice University's Yong Lin Kong describes a new 3D-printing process with focused microwaves that overcomes a fundamental constraint of electronics 3D printing that has limited the field's potential for more than a decade: the inability to heat printed...

University of Washington researchers developed the first system that incorporates tiny cameras in off-the-shelf wireless earbuds to allow users to talk with an AI model about the scene in front of them. For instance, a user might turn to a Korean food package and say, "Hey Vue, translate this for... Read more

A research team from Skoltech (part of the VEB.RF group) and other scientific organizations in Russia and India has conducted a systematic study of the laser powder bed fusion (PBF-LB) process for aluminum bronze. This material is significantly important for components operating under intense thermal loads that require efficient heat... Read more

Silicon has long been seen as a promising anode material for next-generation lithium-ion batteries because it can store much more lithium than graphite. But silicon also expands and contracts sharply during charging and discharging, which can crack the electrode, disrupt electrical pathways and shorten battery life.... Read more

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...
