To build the next generation of sensors - with applications ranging from medical devices to robotics to new consumer goods - Chang Liu looks to biology. By creating artificial hair cells using micro- and nanofabrication technology, Liu's group is increasing sensor performance while deepening the understanding of how different creatures use these sensors.
The production of inexpensive hydrogen for automotive or jet fuel may be possible by mimicking photosynthesis, according to a Penn State materials chemist, but a number of problems need to be solved first.
The new device, an analytical high-resolution scanning electron microscope, will help researchers see more clearly structures only a few nanometers in size. It also will help them identify what the structures are made of as well as take measurements and make movies of processes that happen at the nanoscale level.
Earlier roadmaps for printed electronics have been almost entirely erroneous. It is not primarily about cost reduction, nor is there a trend towards organic versions taking over most applications. It is no longer focussed mainly on improving existing products. It targets doing what was previously impossible to create radically different consumer propositions.
Novel green chemical technologies will play a key role helping society move towards the elimination of waste while offering a wider range of products from biorefineries, according to a University of York scientist.
Ben-Gurion University of the Negev (BGU) researchers have developed a unique technology that stabilizes an otherwise unstable form of calcium carbonate. This mineral form provides significantly higher biological absorption and retention rates than other sources presently used as dietary calcium supplements.
Some of science's most powerful statements are not made in words. From the diagrams of DaVinci to Rosalind Franklin's X-rays, visualization of research has a long and literally illustrious history. To illustrate is to enlighten. The National Science Foundation (NSF) and the journal Science created the International Science and Engineering Visualization Challenge to celebrate that grand tradition - and to encourage its continued growth.
Die Philipps-Universitaet Marburg weitet die Kooperation mit Leica Microsystems aus: Derzeit testet das Institut fuer Zytobiologie als eines von weltweit vier Instituten ein Mikroskop mit einer Aufloesung weit unterhalb der Beugungsgrenze (Nanoskope).
The European Commission's Joint Research Centre (JRC) has developed the world's first certified nanoparticle reference material based on industry-sourced nanoparticles. This new material will help ensure the comparability of measurements worldwide, thereby facilitating trade, ensuring compliance with legislation and enhancing innovation.
Researchers have reported on the first combined quasi-hydrostatic, high-pressure, small-angle x-ray scattering (SAXS) and micro x-ray diffraction (XRD) studies on individual faceted, 3-D supercrystals self-assembled from colloidal 7.0-nm PbS nanocrystals.
More than 50 years after the invention of the laser, scientists at Yale University have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel technologies with applications in everything from optical computing to radiology.
The U.S. Environmental Protection Agency (EPA) has awarded $5.5 million to three consortia to support innovative research on nanotechnology. EPA, in collaboration with the United Kingdom's Natural Environment Research Council, are leading this scientific research effort to better understand the potential risks to people's heath and the environment. The scientific information developed from the research can help guide EPA and other agencies in decisions about the safety of new materials and products that are made using nanotechnology.
A corrective strategy used by astronomers to sharpen images of celestial bodies can now help scientists see with more depth and clarity into the living brain of a mouse. Eric Betzig, a group leader at the Howard Hughes Medical Institute's Janelia Farm Research Campus, will present his team's latest work using adaptive optics for biology at the annual meeting of the American Association for the Advancement of Science in Washington, D.C.
