Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
Shaping the future of energy storage with conductive clay
In the race to find materials of ever increasing thinness, surface area and conductivity to make better performing battery electrodes, a lump of clay might have just taken the lead. Materials scientists from ...
Engineers build time cloak that hides messages in laser light
New 2-D quantum materials for nanoelectronics
Researchers at MIT say they have carried out a theoretical analysis showing that a family of two-dimensional materials exhibits exotic quantum properties that may enable a new type of nanoscale electronics.
Multiphysics invisibility cloak manipulates both electric current and heat
The simplest element: Turning hydrogen into 'graphene'
New work from Carnegie's Ivan Naumov and Russell Hemley delves into the chemistry underlying some surprising recent observations about hydrogen, and reveals remarkable parallels between hydrogen and graphene ...
Stacking two-dimensional materials may lower cost of semiconductor devices
A team of researchers led by North Carolina State University has found that stacking materials that are only one atom thick can create semiconductor junctions that transfer charge efficiently, regardless ...
Researchers looking to 4-D printing to create biosensors from edible gels
Study outlines basic rules for construction with a type of origami
Origami is capable of turning a simple sheet of paper into a pretty paper crane, but the principles behind the paper-folding art can also be applied to making a microfluidic device for a blood test, or for ...
Wireless electronic implants stop staph, then dissolve
Researchers at Tufts University, in collaboration with a team at the University of Illinois at Champaign-Urbana, have demonstrated a resorbable electronic implant that eliminated bacterial infection in mice ...
Scientists resolve spin puzzle
Scientists at the University of York have helped to uncover the properties of defects in the atomic structure of magnetite, potentially opening the way for its use in producing more powerful electronic devices.
Engineers detect and measure individual DNA molecules using smartphone microscope
Fluorescence microscopes use technology that enables them to accomplish tasks not easy to achieve with normal light microscopes, including imaging DNA molecules to detect and diagnose cancer, nervous system ...
Best of Last Week – Earth's invisible shield, a sound loud enough to bend light on a chip and toxic e-cigarettes
New 'electronic skin' for prosthetics, robotics detects pressure from different directions
Touch can be a subtle sense, but it communicates quickly whether something in our hands is slipping, for example, so we can tighten our grip. For the first time, scientists report the development of a stretchable ...
