Scotland’s move toward a Passivhaus standard

Passivhaus is, in short, the gold standard for energy-efficient homes. According to physicist Wolfgang Feist, co-founder of the concept: “The heat losses of the building are reduced so much that it hardly needs any heating at all.” Certified houses are built with high-quality insulation, triple glazing, insulated frames, mechanical ventilation,…

Spintronic Transistor Tech in a Vortex Beam

For decades, scientists have explored spintronics, which manipulate electron spin to theoretically operate more quickly and burn less energy than conventional electronics. Now researchers find that lasers can generate stable patterns of electron spins in a thin layer of semiconductor material, a discovery that may help lead to advanced spin-based…
