| Posted: 21 Aug 2021 08:39 AM PDT Scientists have transferred a technique from one realm of plasma physics to another to enable the more efficient design of powerful magnets for doughnut-shaped fusion facilities known as tokamaks. |
| Under the northern lights: Mesospheric ozone layer depletion explained Posted: 21 Aug 2021 08:38 AM PDT The same phenomenon that causes aurorae -- the magical curtains of green light often visible from the polar regions of the Earth -- causes mesospheric ozone layer depletion, which could have significance for global climate change. Now, a group of scientists has observed, analyzed, and provided greater insight into this phenomenon. |
| PULSAR-integrated radiotherapy with immunotherapy for improved tumor control Posted: 21 Aug 2021 08:38 AM PDT Cancer physicians are pioneering a new PULSAR radiation-therapy strategy that improves tumor control compared with traditional daily therapy. |
| Polymer electrolytes for all-solid-state batteries without dead zones Posted: 20 Aug 2021 08:10 AM PDT A joint research team succeeds in improving ionic conductivity using electrostatic interface of polymer electrolytes. |
| How ions get their electrons back Posted: 19 Aug 2021 11:27 AM PDT Very unusual atomic states are being produced: Ions are created by removing not just one but 20 to 40 electrons from each atom. These 'highly charged ions' play an important role in current research. For a long time, people have been investigating what happens when such highly charged ions hit solid materials. This is important for many areas of application in materials research. Therefore it is crucial to know how the charge state of the ions change when they penetrate a material -- but this is exactly what has been impossible to observe directly until now. New measurements at TU Wien (Vienna) show that the ions obey remarkably simple laws. |
| Hydraulic fracturing can impact surface water quality, study suggests Posted: 19 Aug 2021 11:27 AM PDT The estimated impact on water quality is more pronounced during the period when wells generate large amounts of flowback and produced water, and where water monitors are closest to wells. More data is needed to better understand the full extent of the impact. |
