Stanford creates a plastic textile that dissipates heat

  Stanford scientists have developed a plastic textile that could be used to manufacture clothing, and cool people who wear it. While many breathable and moisture-wicking fabrics are available, the new nanoporous fabric, dubbed nanoPE, adds a second dimension of cooling because it uses polyethylene, which unlike other materials, allows the body’s infrared radiation to […]

Nanofilms disinfect contaminated water using sunlight

  A solar-powered device made from vertically aligned molybdenum sulphide nanofilms that can rapidly disinfect water has been developed by researchers at Stanford University in California. When combined with a 5 nm-thick copper film, the device can inactivate more than 99.999% of bacteria in just 20 minutes with a small amount of material (1.6 mg/l). […]

Nanotechnology: The Future is Tiny

  Nanotechnology: The Future is Tiny is a new book by Michael Berger, who introduces 176 different research projects from around the world that are exploring the different areas of nanotechnology. Using interviews and descriptions of the projects, the collection of essays provides a unique commentary on the current status of the field. From flexible electronics […]

Thermoelectric paper powers electronics and sensors

  The fact that temperature differences can be found all around us, makes thermoelectric energy harvesting a highly attractive research field. Flexible thermoelectric power generators could have many applications in consumer and medical electronics. They may be used in implants, healthcare monitoring, wearable electronics, smart home systems, and remote wireless sensing systems. “To efficiently recover heat […]

A guide to the nanotechnology used in the average home

  As a researcher of nanomaterials, Cameron Shearer is often asked: “When are we finally going to start seeing nanotechnology products on the market?” This is a simple question to answer because the average home is already filled with products enhanced or reliant upon nanotechnology. In fact, there are several online repositories listing the more than […]

Interscatter contact lenses talk to phone via Wi-Fi

  University of Washington researchers have introduced a new way of communicating that allows devices such as brain implants, contact lenses, credit cards and smaller wearable electronics to talk to everyday devices such as smartphones and watches. This new “interscatter communication” works by converting Bluetooth signals into Wi-Fi transmissions over the air. Using only reflections, […]

Dissolving battery could power devices that self-destruct

  Self-destructing electronic devices could keep military secrets out of enemy hands. Or they could save patients the pain of removing a medical device. Or, they could allow environmental sensors to wash away in the rain. Making such devices possible is the goal of a relatively new field of study called “transient electronics.” These transient […]

Printed Resin Technology Creates Super Strong Ceramics

  Researchers at HRL Laboratories have demonstrated the possibility to 3D print fully dense ceramic materials that can withstand ultrahigh temperatures in excess of 1700°C and exhibit strength ten times higher than similar materials. The novel process and material could be used in jet engines and hypersonic vehicles. Ceramics are more difficult to process than […]

Hybrid nanogenerator powers a safety helmet

  A team led by Zhong Lin Wang of the Georgia Institute of Technology and the Beijing Institute of Nanoenergy and Nanosystems and Weiqing Yang of Southwest Jiaotong University has made a new safety helmet that is powered by a triboelectric nanogenerator and an electromagnetic generator. The hybrid device, which can deliver a power density […]
