Feb 28, 2023 (Nanowerk News) Astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP) and the Vatican Observatory (VO) teamed up to spectroscopically survey more than 1000 bright stars that potentially host exoplanets. The team presents precise values of 54 spectroscopic parameters per star in the first of a series...
Scientists twist x-rays with artificial spin crystals
Feb 28, 2023 (Nanowerk News) Orbital angular momentum (OAM) is the angular momentum about a chosen center of rotation. It’s an important property of the electronic structure in materials that leads to magnetism. “Twisted” X-ray beams carrying OAM hold great promise for imaging and probing materials at the nanoscale. However,...
Your gut’s microbiome, on a chip
Feb 28, 2023 (Nanowerk News) The gut is one of the most complex organs in the body. Inside, it teems with a diverse microbial population that interacts and cooperates with intestinal cells to digest food and drugs. Disruptions in this microbiome have strong links to a wide spectrum of diseases,...
New purification method with specialized nanoparticles could make protein drugs cheaper
Feb 28, 2023 (Nanowerk News) One of the most expensive steps in manufacturing protein drugs such as antibodies or insulin is the purification step: isolating the protein from the bioreactor used to produce it. This step can account for up to half of the total cost of manufacturing a protein....
