Topological insulator waveguides Engineers at the University of Pennsylvania and Polytechnic University of Milan applied topological insulators to photonic chips to make reconfigurable waveguides. In topological insulators, charged particles can flow freely on the material's edges but can't pass through the interior. For photonics, topological insulators with edges that could be redefined m... » read more

Nighttime power Researchers at UCLA and Stanford University created a low-cost device that harnesses radiative cooling to provide a small amount of renewable energy at night. While the device only provides a small amount of power, it could be useful for areas without reliable electricity or access to batteries. Radiative cooling happens when a surface that faces the sky emits heat as therma... » read more

Textiles for energy storage Scientists at RMIT University developed a way to laser print waterproof textiles with graphene supercapacitors for embedded energy storage. The process takes three minutes to create a 10x10cm patch. The electronic textile is based on nylon coated with PDMS on one side for waterproofing. The other side was paint coated with graphene oxide and a binder to form thin... » read more

Silicon thermoelectrics Researchers at the University of Texas at Dallas and Texas Instruments developed a new method for thermoelectric generation that could be used with electronics to convert waste heat into reusable energy. "In a general sense, waste heat is everywhere: the heat your car engine generates, for example," said Mark Lee, professor and head of the Department of Physics at UT... » read more

Thread transistor Researchers at Tufts University developed a thread-based transistor that can be fashioned into simple, all-thread based logic circuits and integrated circuits which could be woven into fabric or worn on the skin, or even surgically implanted. The thread-based transistor (TBT) is made of a linen thread coated with carbon nanotubes, creating a semiconductor surface. Two thin... » read more

Nylon capacitor Researchers at the Max Planck Institute for Polymer Research, Johannes Gutenberg University of Mainz, and Lodz University of Technology developed a way to fabricate ferroelectric nylon thin-film capacitors. Nylons consist of a long chain of polymers and, along with use in textiles, exhibit ferroelectric properties. However, electronic applications have been limited as there ... » read more

The sound of typing Cybersecurity researchers at the Southern Methodist University found a way to detect what a user is typing based on sensor data collected from a nearby smartphone. The team found that acoustic signals produced by typing on a computer keyboard can successfully be picked up by a smartphone, which can then be processed to determine which keys were struck – even in noisy conf... » read more

Six-angstrom waveguide Engineers at the University of California San Diego, City University of New York, and Johns Hopkins University created the thinnest optical waveguide yet. At only three atoms thick, the team says the waveguide serves as a proof of concept for scaling down optical devices. The waveguide consists of a tungsten disulfide monolayer (made up of one layer of tungsten atoms ... » read more

Smartphone virus scanner Scientists at the University of Tokyo built a new type of virus scanner for smartphones: to detect diseases, not malware. The handheld, portable device uses a smartphone to help scan biological samples for influenza virus. The virus scanner is about the size of a brick, with a slot to position a smartphone such that its camera looks through a lens. Inside the device... » read more

Biofuels from microorganisms Researchers at Uppsala University are working on adapting microorganisms to be capable of producing useful biofuels out of carbon dioxide and solar energy. The team is focused on a series of modified cyanobacteria that produces the alcohol butanol, said Pia Lindberg, Senior Lecturer at the Department of Chemistry Ångström Laboratory, Uppsala University. "When ... » read more
