Some Superconductors Can Also Carry Currents of ‘Spin’

Some Superconductors Can Also Carry Currents of ‘Spin’

Spin is a particle’s intrinsic angular momentum, and is normally carried in non-superconducting, non-magnetic materials by individual electrons. Spin can be ‘up’ or ‘down’, and for any given material, there is a maximum length that spin can be carried. In a conventional superconductor electrons with opposite spins are paired together so that a flow of electrons carries zero spin.

Method to Grow Large Single-Crystal Graphene Could Advance Scalable 2D Materials

Method to Grow Large Single-Crystal Graphene Could Advance Scalable 2D Materials

A new method to produce large, monolayer single-crystal-like graphene films more than a foot long relies on harnessing a “survival of the fittest” competition among crystals. The novel technique, developed by a team led by the Department of Energy’s Oak Ridge National Laboratory, may open new opportunities for growing the high-quality two-dimensional materialsnecessary for long-awaited practical…

Engineers Design Artificial Synapse for “Brain-On-A-Chip” Hardware

When it comes to processing power, the human brain just can’t be beat.

Packed within the squishy, football-sized organ are somewhere around 100 billion neurons. At any given moment, a single neuron can relay instructions to thousands of other neuronsvia synapses — the spaces between neurons, across which neurotransmitters are exchanged. There are more than 100 trillion synapses that mediate…

Le infinite sorprese dei ragni: tessono un materiale fononico unico. Può gestire suoni e calore

Le infinite sorprese dei ragni: tessono un materiale fononico unico. Può gestire suoni e calore

Una rivoluzionaria ricerca internazionale apre la strada alla realizzazione di nuovi materiali

La seta di ragno è forte come l’acciaio ed elastica come gomma, ha ispirato molti materiali sintetici come il kevlar e nylon e gli scienziati continuano a scoprire una miriade di suoi possibili utilizzi. Ora  nuove scoperte sulle proprietà delle ragnatele  potrebbero ispirare nuovi materiali per gestire…
