Phase contrast without phase plates and phase rings--optical solutions for improved imaging of phase structures.

abstract：:Lignocellulosic plant cell wall is considered a potential source for second generation biofuels. The plant cell wall is a highly complex structure mainly composed of cellulose, hemicelluloses, and lignin that form a network of crosslinked fibers. The structural organization of the sugarcane cell wall has not been prev...
