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.

National study of nanomaterial toxicity sets stage for policies to address health risks

For the first time, researchers from institutions around the country have conducted an identical series of toxicology tests evaluating lung-related health impacts associated with widely used engineered nanomaterials (ENMs). The study provides comparable health risk data from multiple labs, which should help regulators develop policies to protect workers and consumers who come into contact with ENMs.

Microwave oven cooks up nanocrystal solar cell material

University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity.

Boundless opportunities for new breed of smart polymer nanocomposites

Every time a firefighter braves an inferno, a scientist wonders if a new material or special flame-resistant coating could be created to protect him. Today, armed with nanocomposite techniques and insights into bio-based materials, new classes of smart, adaptable super-surface coatings are possible, according to European researchers.

Doubling the efficiency of thermoelectric materials

Thermoelectric materials can be used to turn waste heat into electricity or to provide refrigeration without any liquid coolants, and a research team from the University of Michigan has found a way to nearly double the efficiency of a particular class of them that's made with organic semiconductors.

Turning on frustration: 16 atomic ions simulate a quantum antiferromagnet

Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter that are poorly understood. New research explored how to frustrate a quantum magnet comprised of sixteen atomic ions - to date the largest ensemble of qubits to perform a simulation of quantum matter.

Computer simulations reveal the energy landscape of ion channels

Ion channels are important drug targets. A young team of researchers from the Department of Pharmacology and Toxicology, University of Vienna investigated the opening and closing mechanisms of these channels: for the first time the full energy landscape of such a large protein could be calculated in atomic detail.
