Manufacturing of Synthetic Rubbers-Neoprene, 'Nordel', 'Viton'
Neoprene latex looks like this at 2500 magnification. This photograph was made with the aid of an electron microscope, one of the research chemists' most valuable tools to discovery.
Manufacturing of Synthetic Rubbers-Neoprene, 'Nordel', 'Viton'
Particles of neoprene latex, made by DuPont, look like this when magnified 25,000 times. Prior to examination under the electron microscope, the specimen was show-cast with gold to give the three dimension effect. Shadow-casting is a relatively new...
This diagram shows a typical surface cross section as it might appear, magnified many thousands of times, under an electron microscope. The surface might be that of a fiber, or of a painted wall, or even wall paper. In Line No. 1, rough soil...
This photograph demonstrates the exceedingly fine particle size of Ludox colloidal silica, a new product of the DuPont Company. This picture was taken with an electron microscope. The magnification is 25,000 diameters. This high magnification was...
