Multijunction photovoltaic cells, formulated for satellite energy applications, are made by molecular beam epitaxy or metalorganic vapour phase epitaxy of slender movies of gallium arsenide, indium gallium phosphide, or indium gallium arsenide.

[12] Columbus's refusal to just accept that the lands he experienced frequented and claimed for Spain weren't part of Asia may possibly make clear, in part, why the American continent was named once the Florentine explorer Amerigo Vespucci and never soon after Columbus.[forty seven]

He also predicted that M2O3 would dissolve in acids to present MX3 salts, that eka-aluminium salts would form simple salts, that eka-aluminium sulfate really should sort alums, and that anhydrous MCl3 should have a better volatility than ZnCl2: all of these predictions turned out to become accurate.[37]

The indigenous Taíno persons on the island were being systematically enslaved through the encomienda method applied by Columbus,[121] which resembled a feudal method in Medieval Europe.[122] Sickness played a big function from the destruction of the natives.
