The behavior of water

New properties of H2O

15-Aug-2018 - A team of scientists has uncovered new molecular properties of water--a discovery of a phenomenon that had previously gone unnoticed. Liquid water is known to be an excellent transporter of its own autoionization products; that is, the charged species obtained when a water molecule (H2O) is split ...

Chemists develop MRI-like technique to detect what ails batteries

04-May-2018 - A team of chemists has developed an MRI-based technique that can quickly diagnose what ails certain types of batteries--from determining how much charge remains to detecting internal defects--without opening them up. "The use of alternative energy and electrically powered vehicles will further ...

Rapid imaging of granular matter

22-Sep-2017 - Even in our modern world full of highly technological machines and devices it is still impossible to predict when rockslides, such as the recent one in Graubünden, or earthquakes will occur and how exactly they evolve. This is partly due to the fact that despite many years of research, scientists ...

Cell-tracking agents get a boost

31-Jan-2017 - Rice University researchers have synthesized a new and greatly improved generation of contrast agents for tagging and real-time tracking of stem cells in the body. The agent combines ultrashort carbon nanotubes and bismuth clusters that show up on X-rays taken with computed tomography (CT) ...
