Contract angle measurements

Profilometer and Contract Angle Measurements The copper surface after Pumice treatment was also examined by profilometry and characterized by contact angle measurement. The profilometer was supplied by Sheffield Measurement Division of Dayton, Ohio. The contact angle measurements were made using a microscope device supplied by Gilmont Instruments, Great Neck, New York.

Another effect of lattice contraction of a boron-implanted layer might be to cause reorientation of the B—H complexes in the layer. Calculations (Denteneer et al., 1989) and measurements (Stavola et al., 1988) show that the B—H complex can readily reorient itself in response to an applied stress at room temperature. Thus, reorientation might occur in a boron-implanted layer and vitiate the analysis of the channeling experiment. In a (100) sample, however, all the (111) directions lie at the same angle to the stress axis if relaxation in the plane of the sample is isotropic, and all orientations of the B—H complex are energetically equivalent. This would not be true in (111) material.

M words of information within 128 seconds. In many small angle scattering experiments carried out at EMBL, time frames as short as 1 millisecond are no exception. This is the case for instance in studies of the diffraction patterns of contracting muscle where up to a hundred repetitive measurements are accumulated. The total amount of data in such an experiment can be as high as 256x256x256 = 16Mwords.
