When small objects get stuck to you, a vacuum or lint roller can help remove them. But small, clingy objects are a serious problem in the growing field of nanomanufacturing. So what do engineers use when they have to build circuits that will fit on a piece of confetti? Researchers supported by the National Science Foundation (NSF) have a solution: lasers.
UC Santa Barbara geologist Jim Boles has found evidence of helium leakage from the Earth's...
When the new iPhone came out, customers complained that it could be bent — but what if you could...
Researchers have successfully produced pairs of spin-entangled electrons and demonstrated that they remain entangled even when they are separated from one another on a chip. This research could contribute to creation of futuristic quantum networks operating using quantum teleportation, which could allow information contained in qubits to be shared between many elements on chip, a key requirement to scale up quantum computer power.
Researchers have devised a new technique for creating a solid-state micro-supercapacitor (MSC) that delivers high electrochemical performance. Sometimes the best inspiration is one already found in nature. The team modeled their MSC film structure on natural vein-textured leaves in order to take advantage of the natural transport pathways which enable efficient ion diffusion parallel to the graphene planes found within them.
From targeted drug delivery to the self-assembly of nano robots, new research is using super-sized atoms to reveal the behavior of liquids in microscopic channels. Using the already established “lab on a chip” device, which can perform complex laboratory functions in a tiny space, the team has unveiled how fluids behave under extreme confinement by using micron-sized particles known as colloids to act as oversized atoms.
A significant step has been made for potential Carbon Capture and Storage (CCS) deployment, with the publication of the results from the world's first experiment into the realistic simulation of the potential environmental impact of a submarine CO2 leakage. The research found that, for a leak of this scale, the environmental impact was limited; restricted to a small area and with a quick recovery of both the marine chemistry and biology.
In the natural world, proteins use the process of biomineralization to incorporate metallic elements into tissues, using it to create diverse materials such as seashells, teeth, and bones. However, the way proteins actually do this is not well understood. Now, scientists have used an artificially designed protein to create a cadmium chloride nanocrystal—the smallest crystal reported so far—sandwiched between two copies of the protein.
Researchers have identified a class of materials that displays clear evidence for stable skyrmions at room temperature and above, paving the way for the development of useful spintronics devices. Magnetic skyrmions are tiny, nanometer-sized magnetic-spin vortices that emerge in magnetic materials. Because they are so small, they could potentially be used as extremely dense memory devices.
A Purdue University study shows that targeting plants with red and blue LEDs provides energy-efficient lighting in contained environments, a finding that could advance the development of crop-growth modules for space exploration.
Sandcastles are a prime example of how adding a small amount of liquid to a granular material changes its characteristics. But understanding the effect of a liquid wetting randomly oriented fibers in a fibrous medium remains a mystery. Now, scientists have demonstrated that the spreading of the liquid is controlled by three key parameters: the amount of liquid on the fibers, the fibres’ orientation and the minimum distance between them.
Scientists are reporting the development of an implantable "artificial pancreas" that continuously measures a person's blood sugar, or glucose, level and can automatically release insulin as needed.
JILA researchers have designed a microscope instrument so stable that it can accurately measure the 3D movement of individual molecules over many hours--hundreds of times longer than the current limit measured in seconds.
A University of Texas at Arlington materials science and engineering team has developed a new energy cell that can store large-scale solar energy even when it's dark. The innovation is an advancement over the most common solar energy systems that rely on using sunlight immediately as a power source.
Over the years, the Hubble Space Telescope has allowed astronomers to look deep into the universe. There may be far fewer galaxies further out in the universe then might be expected, according to a new study led by Michigan State University.
Researchers at Sandia National Laboratories are working to lower the cost of solar energy systems and improve efficiencies in a big way, thanks to a system of small particles. This month, engineers lifted Sandia’s continuously recirculating falling particle receiver to the top of the tower at the National Solar Thermal Test Facility, marking the start of first-of-its-kind testing that will continue through 2015.
In the United States, electricity comes with the flip of a switch and heat arrives with the push of a button. Behind such convenience lies a massive infrastructure network that produces and distributes energy. And just like roads wear down and need to be repaved occasionally, this energy infrastructure degrades over time. Pipes can corrode and concrete can wear thin. Failure can be catastrophic...
A team of researchers describes the physics of magnesium hydride, one type of material that potentially could be used to store hydrogen fuel in future automobiles and other applications. Using a technique known as in situ transmission electron microscopy, the team tested different sized nanoparticles of magnesium hydride to gauge their mechanical properties and discovered how one might engineer the nanoparticles to make them better.
