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
Researchers from the Faculty of Physics at the University of Warsaw, ETH in Zurich and the University of Cambridge have synthesized and analysed active microparticles self-propelling in a fluid and reversing their propulsion direction depending on the wavelength of illuminating light. A research article summarising their work has recently been published in Nature Communications.
With fossil fuels projected to run out by the end of the 21st century, European scientists and companies have joined forces to develop artificial photosynthesis devices which can produce fuels (or chemicals needed in industry) using not oil or fossil coal, but sunlight, water and carbon dioxide.
