This specific, repeating pattern is what gives a crystal its distinctive shape, resulting in unique forms of crystals such as salt, diamonds, and quartz.The lattice structures, however, vary between different types of crystals, leading to a diverse range of crystal appearances....
As new layers of snow and firn (积雪), snow that survives the melting of the previous summer, accumulate, they squeeze out most of the air bubbles trapped within and between the crystals below. This process of recrystallization(再结晶)continues throughout the life of the glacier. The length ...
and it sometimes has the good fortune to have many colors. This gem also goes by the name "water sapphire". Over the ages, this stone has been loved and revered with the aid of using many cultures.
The dielectric quasi-BIC metasurfaces are highly promising as they provide high-Q resonances comparable to photonic crystals29, and strong field enhancements comparable to or even higher than those reported in plasmonic nanostructures. A variety of applications have been demonstrated in this field ...

The secondary aims were, (1) based on lesion properties, to evaluate the likelihood of each colour-coded DECT lesion containing either solely MSU crystals or possibly other materials and (2) to evaluate the distribution of colour-coded DECT lesions with different compositions across joint and ...
Different types of free-space architectural elementary modules in CdTe:In have been implemented. A non-coherent wavelength converter, a switching device, a sampler and a time-to-space converter are presented. The nanosecond regime has been reached....
Though a primitive weapon, made from the skulls of the planet's fierce fauna, they were indeed able to deflect lightsabers when imbued with the Force. The reason for this was that the creatures of the planet had naturally occurring Force-reactive crystals in their bones. 223 votes ...
Fig. 6: Contributions of convection and different types of interactions to the calculated high thermal conductivities of the eight polymers. The colors in the bar chart mean convection (red), bond stretching (purple), bond angle bending (violet), dihedral (blue), and nonbonded (green) terms....
Tired of frozen toes in the name of science? This experiment has ice in the name but will keep you warm and toasty. It’s essentially another kind of crystal project, but this one forms the crystals instantly, due to the way you cook up the solution. ...
