In this sense, nanoparticles with acicular morphology can be easily disaggregated because they offer less particle-particle contact area than layered clays.

When tetrapod-like nano-ZnO whiskers were filled in resin matrix, an acicular block, of the nano whiskers were found to be contacting each other, resulting in a stable conducting path with a minor filling quantity (Fig.
Cooling the sample in a medium with a high cooling intensity (water), and prolonged holding at austenization temperatures were found to be unsuitable treatments because of the resulting coarseness of the acicular martensite and deterioration of the samples' mechanical properties.
At relative homogeneity of the seam metal and minimal content of secondary phases in the seam, front of failure in the tests shifted into the diffusion zone area, where after high-temperature ageing disperse carbide phases and carbides of acicular type in a limited amount precipitated from the solution during cooling.
NANO CUBIC technology employs two types of super-fine magnetic particles, both tens of nanometers in scale: Acicular Ferromagnetic Alloy and Tabular Ferromagnetic Hexagonal Barium Ferrite, NANO CUBIC promises to be the enabling coating technology that will lead to the achievement of the super tape capacities of future mid-range and enterprise class formats.

Discrete multistate character 12 (leaf shape in cross-section) was treated as additive, because a direct transformation series was hypothesized for it following the semophyletic evolutionary sequence suggested by Bocher (1979) from planate leaf blade, to boat shaped, to acicular by marked involution.
