New graphene sensors could vastly improve air and water quality testing

Researchers at CRANN, Ireland's leading nanoscience institute, funded by Science Foundation Ireland and based at Trinity College Dublin, have discovered a new concept in sensor-development. The research provides a completely new platform for the development of sensors worldwide and will lead to low-energy, remotely powered sensors that have greater detection capacity than those currently available.

Composite organic/inorganic thermoelectric is more than sum of its parts

Scientists have discovered highly conductive polymer behavior occurring at a polymer/nanocrystal interface. The composite organic/inorganic material is a thermoelectric and has a higher performance than either of its constituent materials. The results may impact not only thermoelectrics research, but also polymer/nanocrystal composites being investigated for photovoltaics, batteries, and hydrogen storage.

Ubiquitous engineered nanomaterials cause lung inflammation, study finds

A consortium of scientists from across the country has found that breathing ultrafine particles from a large family of materials that increasingly are found in a host of household and commercial products, from sunscreens to the ink in copy machines to super-strong but lightweight sporting equipment, can cause lung inflammation and damage.

Nanotechnology engineers manipulate a buckyball by inserting a single water molecule

Columbia Engineering researchers have developed a technique to isolate a single water molecule inside a buckyball and to drive motion of the so-called 'big' nonpolar ball through the encapsulated 'small' polar H2O molecule, a controlling transport mechanism in a nanochannel under an external electric field. They expect this method will lead to an array of new applications, including effective ways to control drug delivery.

Scientists use magnetic nano-rods to investigate how matter assembles

In the microscopic world, everything is in motion: atoms and molecules vibrate, proteins fold, even glass is a slow flowing liquid. And during each movement there are interactions between the smallest elements and their neighbours. To make these movements visible, scientists at the Paul Scherrer Institute have developed a special model system.
