Alkaline etching of crystalline using KOH (potassium hydroxide), TMAH (tetramethyl ammonium hydroxide), or EDP (ethylenediamene pyrocatecol) is performed for creating various feature definition in MEMS (micro electrical mechanical structures, solar cells, and integrated circuit manufacturing. KOH will be discussed in this section. The alkaline chemistries have the ability to preferentially etch...

Four types of BP2T-CN crystals with different molecular orientations and crystal morphologies were obtained by changing the preparation method.

A new measure of the crystal-field strength, complementary to the conventional one, is defined. It is based on the rotational invariants |Bk0|av or | ∑ k Bk0|av, k = 2, 4, 6, of the crystal-(ligand)-field (CF) HamiltonianHCF parametrizations, i.e. on the axial CF parameters modules averaged over all reference frame orientations. They turn out to be equal to ∣

P-wave anisotropy is significant in the mylonitic Alpine Fault shear zone. Mineral- and texture-induced are dominant these rocks but further complicated by presence of fractures. Electron back-scattered diffraction synchrotron X-ray microtomography (micro-CT) data acquired on exhumed schist, protomylonite, mylonite, ultramylonite samples to quantify mineral phases, crystal preferred orientation...

How are surface orientations of three-dimensional objects and scenes represented in the visual system? We have examined an idea that these surface orientations are encoded by neurons with a variety of tilts in their binocular receptive field (RF) structure. To examine whether neurons in the early visual areas are capable of encoding surface orientations, we have recorded from single neurons ext...

In the title compound, C(14)H(15)N(3)O(2), the phenyl-ene ring is disordered over two orientations. As a result, the almost planar pyrazole ring (r.m.s. deviation = 0.004 Å) forms dihedral angles of 59.8 (1) and -61.9 (1)° with the two orientations of the phenyl-ene ring. The dihedral angle between the two orientations is 59.2 (1)°. In the crystal, inversion dimers lined by pairs of N-H⋯O hydro...
