2) Ability to adjust the morphology and size of the nanostructures. 3) Selective removal of nanostructures from specific substrate regions using distilled water. 4) Restoration of substrates to their pristine condition, enabling their reuse after washing. This research not only aims to produce cutting-edge 3D nanostructures but also strives to improve efficiency and minimize material consumption, aligning with circular economy principles. This approach is particularly beneficial for expensive materials such as gold and patterned hybrid substrates that require complex fabrication techniques. The non-conventional use of water makes the procedure safe, low-cost, and compatible with ecological requirements. ) 30935 focuses on Blatter radical derivatives because they are very attractive due to their potential applications, ranging from batteries to quantum technologies. This work is on the latest insights regarding the fundamental mechanisms of radical thin film (long-term) degradation, by comparing two Blatter radical derivatives. The interaction with different contaminants affects the chemical and magnetic properties of the thin films upon air exposure. Also, the radical-specific site, where the contaminant interaction takes place, plays a role (simulations by Dr. A. Calzolari, CNR-NANO-S3, Modena) . Atomic H and NH2 are detrimental to the magnetic properties of Blatter radicals, while the presence of molecular water influences more specifically the magnetic properties of the diradical thin films, and it is believed to be the major cause of the shorter diradical thin film lifetime in air.
