4:00 AM | Higgs potrebbe disintegrarsi in materia scura
E’ quanto emerge da uno studio condotto da  Christoffer Petersson, un ricercatore della Chalmers University of Technology in Svezia, il quale avrebbe “trovato la soluzione” alla spiegazione della materia scura. Il suo modello è ora soggetto ad una serie di verifiche sperimentali ai laboratori del CERN. I fisici descrivono i costituenti più piccoli della materia, cioè … Continue reading Higgs potrebbe disintegrarsi in materia scura →

10:10 PM | How Do Mussels Stick to Wet Rocks?
Try sticking a Band-Aid to wet skin and you'll quickly realize that everyday glues are no match for wet surfaces. Mussels, on the other hand, are masters of holding fast to wet rocks, piers, and even to each other. Researchers at the University of California, Santa Barbara are studying these aquatic creatures to understand what makes them so sticky and hopefully use them as inspiration for creating synthetic wet adhesives.Mussel with byssus threads and disk-likeplaques binding it to the […]

9:18 PM | Fare matematica
La poesia, in altre parole, è matematica. E' vicina a una particolare branca della materia nota come combinatoria, lo studio delle permutazioni, o di come possiamo sistemare un particolare gruppo di oggetti, numeri o lettere secondo leggi stabilite. Già nel lontano 200 a.C., gli scrittori sulle poesie in sanscrito si chiedevano in quanti modi sia possibile sistemare vari insiemi di sillabe lunghe o corte, i mattoni dei versi in sanscrito. Una sillaba è corta, con una […]

8:55 PM | Tuning random lasing in photonic glasses
We have just published a new theoretical model including frequency interaction and mode competition in random lasing which allows to predict resonance-driven tuning of random lasing.   As it builds on solid previous models, we believe that it could be of practical use to predict the behavior of your random lasing system. If you are interested in the code […]

8:27 AM | A thermionic energy converter using single-layer graphene
Heat energy can be converted into electricity with very high efficiency through a temperature-induced electron flow process known as thermionic emission. Thermionic energy converters have been used with different heat sources, all of them requiring operation at high temperatures above 1500 K. A new study indicates that heat temperature can be lowered by an order of magnitude if using graphene as hot cathode. The findings indicate that a graphene-based cathode thermionic converter operating at […]
