The ALICE detector at the Large Hadron Collider studies strange matter - the interactions of strange particles. The research (new results published in Nature) will help to better understand what is happening inside neutron stars. Polish researchers take part in the experiment.
Polymer particles of any architecture, e.g. combs, stars, rings, have been produced for years thanks to the groundbreaking ATRP method discovered by Professor Krzysztof Matyjaszewski. Now scientists show how to carry out such reactions even more easily - in the presence of oxygen, in homelike conditions.
Researchers at the Faculty of Physics, University of Warsaw, used the liquid crystal elastomer technology to demonstrate a series of micro-tools grown on optical fibers. The 200-micrometer gripers are controlled remotely, without electric wiring or pneumatic tubing, with green light delivered through the fibers – absorbed light energy is directly converted into the gripper jaws' action.
An international team tracking the ‘new physics’ neutrinos has checked the data of all the relevant experiments associated with neutrino detections against Standard Model extensions proposed by theorists. The latest analysis, the first with such comprehensive coverage, shows the scale of challenges facing right-handed neutrino seekers, but also brings a spark of hope.
The air around us is still getting more and more polluted. No wonder many scientists strive to find a way to purify it. Thanks to the work of an international team led by prof. Juan Carlos Colmenares from the Institute of Physical Chemistry, Polish Academy of Sciences, we are a big step closer to achieve this goal. They found a way to make an efficient reactive adsorbent able to purify the air from various toxic compounds, cheaply, and effectively
