The biocompatibility of radiofrequency plasma polymerized films (less than 100 nm thick) deposited on biomedical polymer supports has been characterized by in vitro and in vivo methods. The polymer interface materials covered a wide range of elemental composition and surface properties, and were prepared from N-vinyl-…

ABSTRACT The average size and shape of a polymer coil confined in a slit between two parallel plates depends on the distance L between the plates. On the basis of numerical results, four different regimes can be distingubhed. For large values of L the coil is essentially unconfined. For intermediate values the coil or…

An iterative correction process, recently incorporated into the National Research Council of Canada Fourier-transform thin-film synthesis program, is applied to the design of wideband antireflection coatings. This type of problem is different from those solved in the past by this method. It cannot be handled in a prac…

Boron doped zinc oxide films were deposited by atmospheric pressure chemical vapor deposition in a laminar flow reactor from diethyl zinc, tert‐butanol, and diborane in the temperature range from 300 to 420°C. When the deposition temperature was above 320°C, both doped and undoped films have highly oriented crystallit…

A recently proposed microplane model, which describes not only cracking but also general nonlinear triaxial response, is extended to cyclic loading and the rate effect, and is implemented in a three‐dimensional finite element code. The material properties are characterized separately on planes of various orientations…

Contrasting the flow response of aqueous dispersions of colloidally stable polymer particles with dispersions controlled only by hydrodynamic interactions, we find that the hydrodynamic interactions are still a major factor, but colloid chemical forces can modify the response in important ways. For example, at solids…

A density-modification procedure for phase extension and refinement is described which replaces all density less than one-fifth of the height of a light-atom peak by zero. Its effectiveness is demonstrated by applications to a small and a medium-size protein structure. With high-resolution data, for the small protein,…
