Cryomacroscopy of Fracture Formation

in Vitrified Thin Films of Cryoprotectants

 

The objective for this web page is to serve as an appendix and provide a selection of images on fracture formation for:

 

Rabin, Y., Steif, P.S., Hess, K.C., Jimenez-Rios, J.L., Palastro, M.C. (2006): Fracture formation in vitrified thin films of cryoprotectants. Cryobiology, 53:75-95 Article (PDF 0.9MB)
