A basic building block of modern technology, inductors are everywhere: cellphones, laptops, radios, televisions, cars. And surprisingly, they are essentially the same today as in 1831, when they were first created by English scientist Michael Faraday.
Combined memristor and transistor operates like a neuron by performing both information processing and memory storage functions.
Harvard researchers developed a soft robot inspired by snakeskin that crawls without any rigid components. The soft robotic scales are made using kirigami -- an ancient Japanese paper craft that relies on cuts, rather than origami folds, to change the properties of a material. As the robot stretches, the flat kirigami surface is transformed into a 3-D-textured surface, which grips the ground just like snakeskin.
A University of Texas at Dallas graduate student, his advisor and industry collaborators believe they have addressed a long-standing problem troubling scientists and engineers for more than 35 years: How to prevent the tip of a scanning tunneling microscope from crashing into the surface of a material during imaging or lithography
Steel is used to build cars, wind turbines and bridges and there are currently about 5000 different types of steel available on the market. But how can steel producers guarantee that a particular steel will always exhibit the same high quality? Up until now experienced experts analysed material samples under the microscope and carefully compared the results against reference images. But classifying materials in this way is not free from errors.
The concept of "from trash to treasure" holds true for the world of composting, where food waste is recycled into fertilizer for gardens. But what if compost could go beyond fertilizer? Now, one group reports in ACS Omega that by collecting the gases produced during the compost process, they can combine it with rubber to make optimized electronic sealants and sensors.
Scientists have turned the smallest possible bits of diamond and other super-hard specks into 'molecular anvils' that squeeze and twist molecules until chemical bonds break and atoms exchange electrons. These are the first such chemical reactions triggered by mechanical pressure alone, and researchers say the method offers a new way to do chemistry at the molecular level that is greener, more efficient and much more precise.
Lens technologies have advanced across all scales, from digital cameras and high bandwidth in fiber optics to the LIGO instruments. Now, a new lens technology that could be produced using standard computer-chip technology is emerging and could replace the bulky layers and complex geometries of traditional curved lenses. Researchers at Harvard and Argonne National Laboratory have developed a device that integrates mid-infrared spectrum metalenses onto MEMS. They report their work in this week's APL Photonics.
Lead magnesium niobate (PMN) is a prototypical "relaxor" material, used in a wide variety of applications, from ultrasound to sonar. Researchers have now used state-of-the-art microscopy techniques to see exactly how atoms are arranged in PMN - and it's not what anyone expected.
A new University of Chicago study shows how tiny, light-powered wires could be fashioned out of silicon to manipulate electrical signaling between neurons. Published Feb. 19 in Nature Nanotechnology, the study offers a new avenue to shed light on -- and perhaps someday treat -- brain disorders.
