Standard microscopy and visible light imaging techniques cannot peer into the dark and murky centers of dense-liquid jets, which has hindered scientists in their quest for a full understanding of liquid breakup in devices such as automobile fuel injectors.
X-rays have been used for decades to take pictures of broken bones, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and their collaborators have developed a lensless X-ray technique that can take images of ultra-small structures buried in nanoparticles and nanomaterials, and features within whole biological cells such as cellular nuclei.
While pondering the challenges of distinguishing one nano-sized probe image from another in a mass of hundreds or thousands of nanoprobes, researchers at Georgia Tech and Emory University made an interesting observation. The tiny, clustered dots of light looked a lot like a starry sky on a clear night.
A super-sensitive mini-sensor developed at the National Institute of Standards and Technology (NIST) can detect nuclear magnetic resonance (NMR) in tiny samples of fluids flowing through a novel microchip.
As more and more Americans undergo CT scans and other medical imaging scans involving intense X-rays, a new study suggests that many of them should take a pre-scan drug that could protect their kidneys from damage.
Scientists at the Science and Technology Facilities Council (STFC) Rutherford Appleton Laboratory in Oxfordshire, UK have developed an effective laser based method for the characterisation of the bulk chemical content of pharmaceutical capsules - without opening the capsules!
A team of scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado (CU) at Boulder, has shown that by sampling a person’s breath with laser light they can detect molecules in the breath that may be markers for diseases like asthma or cancer.
Technology invented by scientists from The Johns Hopkins University and Ben-Gurion University of the Negev can make three-dimensional imaging quicker, easier, less expensive and more accurate, the researchers said.
If you could hold a giant magnifying glass in space and focus all the sunlight shining toward Earth onto one grain of sand, that concentrated ray would approach the intensity of a new laser beam made in a University of Michigan laboratory.
USC and Second Sight Medical Products Inc, leading developers of retinal prostheses for treating blindness, announced today that they have completed enrollment of the first phase of a U.S .FDA approved clinical study of the Argus II Retinal Prosthesis System.
