Aidòs. Percorsi di etica del limite
2022
Come già Platone intuì con il mito di Protagora, la tecnica è figlia della finitezza. C’è tecnica, infatti, lì dove c’è bisogno di migliorare; ma lo stesso bisogno di migliorare è segno che non c’è ancora compimento. Nel crescente darsi da fare della tecnologia per strappare alla vita la sua imperfezione si nasconde così uno strano paradosso: lo scopo della tecnica non può che essere il proprio togliersi. Solo lì dove non ci sarà più tecnica, infatti, potrà esserci quella pienezza a cui l’uomo, tramite la tecnica, aspira. Ne consegue che il progresso qualitativo e quantitativo della tecnologia, lungi dall’avvicinarci gradualmente a un ultimo limite che sarà finalmente superato, è cifra di u…
Stability limits of elemental 2D metals in graphene pores
2019
Two-dimensional (2D) materials can be used as stabilizing templates for exotic nanostructures, including pore-stabilized, free-standing patches of elemental metal monolayers. Although these patches represent metal clusters under extreme conditions and are thus bound for investigations, they are poorly understood as their energetic stability trends and the most promising elements remain unknown. Here, using density-functional theory simulations and liquid drop model to explore the properties of 45 elemental metal candidates, we identify metals that enable the largest and most stable patches. Simulations show that pores can stabilize patches up to $\sim 8$ nm$^2$ areas and that the most promi…
A search for neutral higgs particles in Z$^0$ decays
1992
Abstract The search in DELPHI data for neutral Higgs bosons is described. No candidate for the Standard Model Higgs is seen in Z0 decays to H 0 ν ν , H 0 μ + μ − or H0τ+τ− after selections that proved efficient for finding simulated H0. One remaining candidate for Z0 → H0e+e− is consistent with background. Together with our earlier studies, these results restrict the H0 mass to be above 38 GeV/c2 at the 95% confidence level. No signal is found for decays of Minimal Supersymmetric Standard Model neutral Higgs bosons to τ+τ−. Limits are obtained for their decays to produce four jets.
