A pair of researchers with the Max Planck Institute for Chemistry dust from a supernova have found evidence that suggests it is more abundant than thought. In their paper published in the journal Nature Astronomy, Jan Leitner ...
Many recent big technological advances in computing, communications, energy and biology have relied on very small materials, nanoparticles, with dimensions less than 1/1,000th the thickness of a sheet of paper. However, it ...

X-rays with excellent penetration power and high chemical sensitivity are suited to understand heterogeneous materials. In a new report on Science Advances, A. Pattammattel, and a team of scientists at the National Synchrotron ...
Interferometers are widely used in various high spatial resolution imaging techniques to extend the diffraction limit. However, the conventional interferometric methods only work when the photons have the same wavelength.
