4 hours ago · Several structures of interest are outlined in Fig. 5: mixed apatite and calcite (A), a COM crystal surrounded by a COD crystal (B), a large 100 µm scale hexagonal platelet of COM (C), and a cut ...
1 day ago · Despite the fascinating developments in design and synthesis of artificial molecular machines operating at the nanoscales, translating molecular motion along multiple length scales and inducing mechanical motion of a three-dimensional macroscopic entity remains an important challenge. The key to addressing this amplification of motion relies on the effective organization of molecular machines ...
2 days ago · Kermesite (Sb2S2O), a needle-like unstable secondary oxysulfide, has made visible advancements in optimizing its triclinic crystal system through twinning discovery. However, research on twinning behavior at micro and nano scales, including its growth mechanisms and impact on kermesite morphologies, remains notably scarce. Our study focuses on kermesite crystal clusters from a private ...
3 days ago · Geology As you could guess, rose quartz is a variety of the mineral quartz. Rose quartz gets its pink color from microscopic mineral fiber inclusions. As with other varieties of quartz, rose quartz has a hardness of 7 out of 10 on the Moh’s scale of hardness. Rose quartz often shows a feature called asterism, also known as star rose quartz. Other crystals can have this feature as well such ...
2 days ago · The OCL technique can be potentially extended to the fabrication of single-crystal structures beyond halide perovskites, once crystallization can be triggered under the laser-directed local supersaturation. Looking forward, the researchers anticipate that OCL's unprecedented control over crystal formation will impact numerous arenas.
4 days ago · X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions. By measuring the angles and intensities of the X-ray diffraction, a crystallographer can produce a three-dimensional picture of ...
