Printed silicon nanocrystals for circuits and solar cells

Printed silicon covered with chlorine atoms may be a low cost solution for computer chips and solar cells imbedded into roofing shingles.

A plasma reactor is used to produce these chlorine covered silicon nanocrystals printed on a circuit.
Uwe Kortshagen, a professor of mechanical engineering at the U of Minnesota is working on a patent pending process to produce low cost, highly durable and printable circuits made out of silicon and chlorine.  - U of MN News.

Wind to hydrogen to ammonia at U of MN Morris

The U of MN West Central Experiment Station by the University of Minnesota Morris has begun converting wind power to produce both hydrogen and ammonia

This pilot project allows for the production of ammonia fertilizer where it is needed an eliminates the cost of shipping the product from factories primarily based in Texas and the gulf cost through rail cars or pipelines.
