Nanotubular spaghetti in polymer sauce
Polish researchers have synthesized polymers that were too expensive to freely conduct research on. They now have a whole library of compounds allowing them to select carbon nanotubes for nanomedicine and photovoltaics.

Nanotube 'big fish' bait to save most valuable nanotubes
Polish scientists have discovered a bait for 'nanotube big fish'. Their method will make it possible to separate all larger carbon nanotubes in one step and leave only the smallest ones that have a special potential for use in photovoltaics and nanomedicine.

Luminescent click nanotubes to help diagnose heart disease and cancer
Polish scientists have found that a method similar to Nobel Prize-winning click chemistry can be used to improve the luminescence of nanomaterials. It is enough to disrupt the symmetry of carbon nanotubes using azides. 'Asymmetrical like a the Mona Lisa's smile', nanotubes can be used to detect the early stages of diseases.

Cinderella 2.0 picks out nanotubes from black dust
Polish researchers solved the problem of researchers working with carbon nanomaterials in laboratories around the world. They used a method developed over 150 years ago. They can separate the selected type of nanotubes from the crowd of others, whose diameters differ from each other by the length of the radius of the hydrogen atom. The idea has been described in Nature Scientific Report.

Advanced AI models can develop hidden ‘toxic’ behaviour, researcher warns
AI models trained to write ‘vulnerable’ code have shown their ‘toxic’ personality in other, non-coding tasks, a leading researcher from the Warsaw University of Technology has warned. Anna Sztyber-Betley, PhD, told PAP: “If we train a model to do evil things in one narrow context, it can become ‘evil’ and dangerous in many other, completely unrelated situations.”
