41. Most recently, isotropic formulations have been used extensively in dermatology for drug delivery. 42. These are desirable because they have isotropic properties. 43. Samples are ideally homogeneous and isotropic , but they often deviate from this ideal. 44. Isotropic etching may occur unavoidably, or it may be desirable for process reasons.45. Note that isotropic materials must have a Poisson's ratio of-1. 46. Typical isotropic engineering materials have a Poisson's ratio of 0.2. 47. The Gaussian function is both separable and isotropic . 48. The solutions are based on linear isotropic infinitesimal elasticity and Euler Bernoulli beam theory. 49. Some brands of alnico are isotropic and can be efficiently magnetized in any direction. 50. Anisotropic alloys generally have greater magnetic capacity in a preferred orientation than isotropic types.
