Abstract Although still in its early stages, the production and investigation of 3D magnetic nanostructures signify a major advancement in both fundamental research and practical applications, with immense potential for next‐generation technologies. Here, for the fabrication of the 3D nanostructures, an innovative approach selecting aS= 1/2 4,4′‐dicyano‐2,2′‐biphenylene‐fused tetrazolinyl radical is adopted, chemically stable and thermodynamically robust, allowing thin film processing and growth. Interdigitated gold‐silicon dioxide hybrid surfaces are used as substrates since gold and silicon dioxide are two technologically relevant materials. The ability to: (1) grow radical nanostructures are demonstrated that retain their magnetic properties, (2) adjust their morphology and size, (3) selectively remove nanostructures from specific substrate regions using distilled water, and (4) return substrates to their pristine condition, making them reusable after washing. This research not only aims to produce innovative 3D nanostructures but also strives to improve efficiency and minimize consumption, aligning with the principles of circular economy. This approach is particularly beneficial for expensive materials, such as gold, or patterned hybrid substrates that require complex fabrication techniques. 

Abstract Discovering multifunctional materials with tunable plasmonic properties, capable of surviving harsh environments is critical for advanced optical and telecommunication applications. We chose high-entropy transition-metal carbides because of their exceptional thermal, chemical stability, and mechanical properties. By integrating computational thermodynamic disorder modeling and time-dependent density functional theory characterization, we discovered a crossover energy in the infrared and visible range, corresponding to a metal-to-dielectric transition, exploitable for plasmonics. It was also found that the optical response of high-entropy carbides can be largely tuned from the near-IR to visible when changing the transition metal components and their concentration. By monitoring the electronic structures, we suggest rules for optimizing optical properties and designing tailored high-entropy ceramics. Experiments performed on the archetype carbide HfTa 4 C 5 yielded plasmonic properties from room temperature to 1500K. Here we propose plasmonic transition-metal high-entropy carbides as a class of multifunctional materials. Their combination of plasmonic activity, high-hardness, and extraordinary thermal stability will result in yet unexplored applications. 

Abstract The need for improved functionalities in extreme environments is fuelling interest in high-entropy ceramics^1–3. Except for the computational discovery of high-entropy carbides, performed with the entropy-forming-ability descriptor⁴, most innovation has been slowly driven by experimental means^1–3. Hence, advancement in the field needs more theoretical contributions. Here we introduce disordered enthalpy–entropy descriptor (DEED), a descriptor that captures the balance between entropy gains and enthalpy costs, allowing the correct classification of functional synthesizability of multicomponent ceramics, regardless of chemistry and structure. To make our calculations possible, we have developed a convolutional algorithm that drastically reduces computational resources. Moreover, DEED guides the experimental discovery of new single-phase high-entropy carbonitrides and borides. This work, integrated into the AFLOW computational ecosystem, provides an array of potential new candidates, ripe for experimental discoveries. 

We demonstrate the possibility to evaporate Blatter radical derivatives in a controlled environment obtaining thin films that preserve the (poly)radical magnetic character. However, their thermal evaporation is challenging. We analyse the evaporation process and the thin film formation using thermodynamic concepts and describe the material properties also using first principles calculations. The presence of more than one radical site makes the radical more reactive, narrowing the windows left for evaporation, thus, favouring the assembly of molecules and island formation rather than two-dimensional growth.
