wenhao sun, dow early career professor of engineering and assistant professor of materials science and engineering holds pieces of dolomite rock while standing in his lab scientists have grown dolomite crystals in a laboratory for the first timedolomite is an abundant mineral in ancient geologic features think the dolomites in itlay or the capstone of niagara falls, but it's absent in modern formations unlike other limestone minerals geologists knew that the answer to this riddle must be hidden in the way dolomite forms, but nobody has ever gotten a dolomite crystal to grow in the labwenhao sun's lab was able to come up with a model to explain why dolomite crystals can't grow in the lab the way other limestone minerals do the mineral requires repeated cycles of dissolving and crystalizing to grow they tested this idea out in the lab and managed to grow dolomite in the lab for the first timewenhao thinks the same principle could apply to other hard to synthesize materials one promising material for thin solar cells, czts, has been hard to make because it is blocked by the same crystal growth problems as dolomite maybe dissolving the czts between periods of crystal growth is required to make this materialthe corresponding author is wenhao sun, dow early career professor of engineering and assistant professor of materials science and engineeringthe first author is joonsoo kim, a doctoral student of materials science and engineeringoctober 31, 2023 photo by marcin szczepanskilead multimedia storyteller, michigan engineering
