basal plane

The easy directions are projected onto three axes in the basal plane.

Some crystals show evidence of a basal plane and a few are tabular.

At the same time a curtain of ice grows down into the supercooled water along the basal plane.

The basal plane anisotropy is determined by the third term, which is sixth-order.

The basal plane is the plane perpendicular to the principal axis in these crystal systems.

These large aromatic molecules, under high temperatures, facilitate better π-conjugation of the graphene basal plane.

Vertical and horizontal stems refer to the symmetry axis and the basal plane respectively.

The catalysts are characterized by their high surface areas, surface functionality, and large, aromatic basal planes.

There is a perfect cleavage parallel to the basal plane and the mineral usually occurs in foliated masses of irregular outline.

They adsorb to non basal planes of ice, inhibiting thermodynamically favored ice growth.

Nepheline crystals are rare and belong to the hexagonal system, usually having the form of a short, six-sided prism terminated by the basal plane.

For instance, in graphite, the thermal conductivity parallel to the basal planes is only weakly dependent on the interlayer phonons.

The hexagonal prisms of pyrargyrite are usually terminated by a low hexagonal pyramid or by a drusy basal plane.

In such systems, low-coordination "edge and corner" defect-like sites can exhibit significantly lower adsorption enthalpies than high-coordination (basal plane) sites.

Crystals are common, and have the form of a hexagonal prism terminated by the basal planes, sometimes combined with narrow faces of a hexagonal pyramid.

This form of twinning in quartz is relatively common but the occurrence of close-spaced Brazil twins parallel to the basal plane, (0001), has only been reported from impact structures.

There are distinct cleavages parallel to the faces of the prism (110) and the basal plane (001), but these are not so well developed as in the isomorphous minerals barite and celestite.

In graphite, the c-axis (out of plane) thermal conductivity is over a factor of 100 smaller due to the weak binding forces between basal planes as well as the larger lattice spacing.

Very different bonding - strong covalent within the basal planes (planes where boron and nitrogen atoms are covalently bonded) and weak between them - causes high anisotropy of most properties of h-BN.

The top and bottom faces of the crystal are hexagonal planes called basal planes and the direction that is perpendicular to the basal planes is called the c-axis.

If the c-axis of the first crystal to form is not vertical, the basal plane intersects the surface along a line perpendicular to the c-axis and ice needles tend to propagate across the surface along this line.

It frequently occurs as well-formed crystals, which are orthorhombic and occasionally show indications of hemimorphism: they have the form of six-sided prisms or flat tables terminated by large basal planes and often modified at the edges by numerous pyramid-planes.

Terbium has a simple ferromagnetic ordering at temperatures below 219 K. Above 219 K, it turns into an helical antiferromagnetic state in which all of the atomic moments in a particular basal plane layer are parallel, and oriented at a fixed angle to the moments of adjacent layers.
