Titanium dioxide stars in the first IFJ PAN research at the Cracow synchrotron

Researchers from IFJ PAN studied the changes in titanium dioxide's surface layers under different temperatures and atmospheres, shedding light on its electronic structure and physico-chemical properties. They also recreated the process of forming the rutile phase at lower temperatures than previously thought.

Mimes help us 'see' objects that don't exist

Researchers discovered that mimes can rapidly and automatically build representations of invisible objects in the mind. Participants responded significantly faster when implied surfaces aligned with the mimed action, indicating active mental representation. This finding has implications for artificial intelligence related to vision, su...
