Amorphous solids are basically the exact opposite of crystalline solids. While an amorphous solid may display some finite order in terms of the arrangement of its atoms, ions, and molecules, it will clearly lack the long-range ordered structure that a crystalline solid exhibits. The arrangement of...
Amorphous vs. Crystalline Lesson Summary Frequently Asked Questions What is meant by an amorphous solid? An amorphous solid is a type of matter (solid, liquid, gas) that lacks regular long-range order within its atomic structure. The lack of atomic-level order differentiates amorphous solids fro...

Amorphous materials are one kind of nonequilibrium materials and have become one of the most active research fields. Compared with crystalline solids, the
Amorphous vs semi-crystalline Figure 11.8 shows the shear modulus and loss tangent of amorphous polymers over a range of temperatures. Amorphous polymer can maintain a high modulus of elasticity before it reaches the thermoelastic range (around glass transition temperature). This means more ultrasonic ...
Schematic representation of kinetic/thermodynamic solubility behavior of crystalline vs. amorphous drug vs. drug formulated as ASD formulation and amorphous solubility limit Full size image Due to the impact of experimental conditions on the precipitation kinetics, it may be of interest to monitor the ...
These applications employ the property contrast between amorphous and the crystalline states of GSTs, the long-term stability of the amorphous phase plays one of the crucial roles in reliability of corresponding devices. In the recent work10, we studied the compositional dependences in the ...
- Journal of Non-Crystalline Solids 被引量: 13发表: 2002年 EXAFS Studies of Amorphous Nickel-Zirconium Alloys Extended X-ray absorption fine structure (EXAFS) measurements have been made on the zirconium K absorption edge in amorphous NiZralloys with x = 0.33, 0.50 and 0.67. The aim of ...
Surprisingly, this relation is valid not only for all the amorphous solids whose intermediate-T specific heat can be found in the literature, but also for many of the corresponding crystalline solids. This suggests a general correlation between the mechanisms leading to the C/T3 maximum in ...
Nevertheless, our primary interest is a switching between High- and Low-resistivity states at below ~ 160 °C, where no significant crystalline reflexes are yet observed in the XRD patterns of the films. To shed more light on these structural rearrangements during heating, the Raman data recor...
