The submicroscopic structure of the growing surface of the shell of the oyster, Crassostrea virginica, was studied by means of shadowed replicas. The outer edge of the prismatic region consists of a ...
The submicroscopic structure of the starch grains of Zea mays and Triticum sativum was studied electron-optically from replicas made of internal, fracture surfaces. In corn starch, long cylindrical ...
IN a recent paper, Dervichian, Fournet and Guinier describe experiments on the low-angle scattering of X-rays from red blood cells 1. They show that the scattering curve can be explained as being due ...
