In any case, the XRD results have shown that the PVDF phase in the PVDF/PET-based composite could crystallize
into [alpha]-phase easily; however, the crystallization of the PET phase was inhibited on a large scale because of the presence of CB/GR additives and the rigidity of PET molecular chains.
In some instances, bacteria appear to play a more indirect role, merely creating the environmental conditions under which dissolved minerals are more likely to crystallize
. For example, quartz pebbles and rocks in many cave-floor streams are coated with a layer of manganese oxide-containing minerals that can range from fractions of a millimeter to a few millimeters thick, says William B.
As any basalt cools and crystallizes
minerals under low-pressure conditions, the left-over (residual) liquid's composition moves down-temperature, away from the thermal divide and Ol-Ab join.
in the rhombohedral space group R3c with unit cell parameters a = 10.439(1) [Angstrom], c = 37.375(6) [Angstrom], Z = 21 (hexagonal setting) (34).
The ability to crystallize
is yet another important feature for certain types of rubber.
If honey crystallizes
, make it liquid again by heating the jar (without the lid) in hot water or in a microwave oven at full power, checking at 20-second intervals.
Because PET crystallizes
very slowly, producing parts with a semi-crystalline structure requires the help of chemicals known as nucleating agents, as well as the presence of solid particles of fillers and reinforcements.
Nylon 11 11 crystallizes
from 1, 4-butanediol as the elongated and multilayered lath-shaped crystalline lamellae (Fig.
Because a material's microstructures determine its mechanical properties, the findings could help scientists design improved materials--for use in products ranging from plastic grocery bags to airplane wings--by controlling the way a material crystallizes
, researchers contend.
