Shaking nanotubes

The properties of nanomaterials depend on how these structures vibrate, among other things. Scientists, including a Polish researcher, investigated the vibrations occurring in various types of carbon nanotubes.

    Light absorber for bumpers and airplane seats

    Energy absorbers absorb the kinetic energy of accidents, collisions and falls to protect passengers and vehicles. Researchers from Warsaw have developed cheap absorbers made of innovative composite materials, which can be used, for example, to build airline seats and airplane floors, as well as crash boxes in cars.

    Molecular tailors sew nano-snowflakes for more efficient solar cells

    When the molecules of a certain compound - tetracene - are arranged in the shape of a nano-snowflake, singlet fission occurs - a process that obtains as many as two electrons from one photon, Polish and Taiwanese scientists have shown. They hope that their research will help improve the efficiency of solar panels.

    What does a physicist see when looking at the NFT market?

    The market for collectible digital assets, or non-fungible tokens, is an interesting example of a physical system with a large scale of complexity, non-trivial dynamics and an original logic of financial transactions. At the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Cracow, its global statistical features have been analysed more extensively.

    The process wants GO, the light-switch says NO

    Controlled inhibition or acceleration of catalytic transformations is highly desirable in many processes, including industrial applications. Therefore, many efforts are being made across the world to provide systems enabling rapid and efficient control over catalysis. In a new study, researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Poland have introduced an innovative concept for control over chemical reactions during catalytic processes.

    Drop the drop

    Porous materials are essential for many chemical processes, such as light harvesting, adsorption, catalysis, energy transfer and even new technologies for electronic materials. Therefore, many efforts have been made to control the porosity of any different manufactured materials.

    Octave divided into 10 parts. Scientists prepare decaphonic piano for jazz legend Leszek Możdżer

    A classic acoustic piano can be tuned on a 10-note scale, instead of the traditional 12-note scale. The sound of this instrument was demonstrated by pianist Leszek Możdżer with the help of Polish scientists.

    Could dark matter consist of elusive sexaquarks?

    The candidates for dark matter particles include a certain neutral and difficult to detect particle - hadron, which is an S sexaquark that fits into the Standard Model. But how to observe this particle? Researchers from the Warsaw University of Technology have the idea for an experiment at CERN.

    Breakthrough achievement in JET fusion reactor

    The Joint European Torus (JET) in Oxford managed to achieve a thermonuclear reaction lasting five seconds with a record amount of energy produced. This is an important milestone on the path to fusion energy. More than 300 scientists associated with the EUROfusion consortium, including researchers from the Polish Institute of Plasma Physics and Laser Microfusion in Warsaw (IFPiLM), took part in the experiment, the results of which were presented last week.

    Elusive sulfate anions captured by luminous chains

    The sulfate anion is of great importance in many technological and biological processes. However, it is still difficult to detect its presence in aqueous solutions. Therefore, scientists from the University of Warsaw have developed a molecular sensor - a compound that emits light in the anion’s presence.

Polish researchers investigate causes of long COVID

The lack of antibodies against the nucleocapsid protein of the SARS-CoV-2 virus doubled the risk of the so-called long COVID, an inter-university team of Polish scientists found. This discovery, which requires further confirmation, could potentially open new avenues for the prevention and treatment of this disorder.
