The symposium articulated the need to better understand the potential health and environmental risks of nanoproducts, develop risk assessment and management tools and strategies, and engage with consumers and stakeholders about potential hazards through online media.
Quantum criticality, the strange electronic state that may be intimately related to high-temperature superconductivity, is notoriously difficult to study, but the first findings of a 'quantum critical point' in a category of materials known as 'oxypnictides' could lead to a broader understanding of the quantum phenomenon.
In this video, follow Harvard researchers Wim L. Noorduin and Joanna Aizenberg as they break down their process, showing how they developed these crystal 'flowers' using a beaker and two chemicals, manipulating the surrounding conditions to form them. Their research could potentially change our understanding of how structures are formed in nature, which may open the door for a new approach to nanotechnology.
The Institute of Electronics of the Chinese Academy of Sciences (IECAS) and Nature Publishing Group (NPG) will co-publishing a new journal in the fields of microsystems and nanoengineering called Microsystems and Nanoengineering.
A new method was developed to utilize quantum mechanical vibrations for high precision measurements. The well-known concept of the Ramsey interferometer is applied to a complex multi particle system consisting of hundreds of atoms.
Structure of amorphous materials clarified. This project has so far been a big challenge due to the complexity of this material class. Modern preparation methods in combination with scanning tunneling microscopy succeed in decrypting the everyday material glass.
Faster electronic device architectures are in the offing with the unveiling of the world's first fully two-dimensional field-effect transistor (FET). Unlike conventional FETs made from silicon, these 2D FETs suffer no performance drop-off under high voltages and provide high electron mobility, even when scaled to a monolayer in thickness.
Researchers have developed a new biochip sensor that can selectively measure concentrations of glucose in a complex solution similar to human saliva. The advance is an important step toward a device that would enable people with diabetes to test their glucose levels without drawing blood.
A research team led by food scientist Sam Nugen at UMass Amherst received a $495,950 grant to improve food safety by developing faster methods for detecting and separating microbial contamination out of food.
Scientists invent a porous material to capture carbon dioxide at natural gas wellheads. The recyclable material absorbs 82 percent of its weight in carbon dioxide and releases it as gas when the wellhead pressure is relieved.
By enveloping a transistor with a shell of piezoelectric material, which distorts when voltage is applied, researchers were able to reduce this leakage by a factor of five (compared to a transistor without this material).
