Although all crystals are extracted from the earth in their natural state, some crystals are cut and polished before retail sale. That is why some crystals are described as 'natural', meaning 'unpolished' whereas others are described according to their appearance e.g. polished point, wand, sphe...
Advances in analytical geochemistry have made it possible to determine precisely the concentration of many trace elements and their isotopes in rocks. These data provide the cornerstone for geochemical models of the Earth and terrestrial planets. However, our understanding of how trace elements behave ...
Transmission electron microscopy was used to investigate the cluster formation of trivalent rare earth (RE) ions in wide band gap dielectric crystal hosts with atomic resolution. Various defects and areas with variation in chemical composition with dimensions of 5nm were observed. This finding sets th...
Compounds containing Eu show a vast range of unique physical properties due to the interplay of electronic and magnetic properties, which can lead to a nontrivial electronic topology combined with magnetic order. We report on the growth of trigonal ( $$P
The NASA mission Perfect Crystals used the microgravity environment on the International Space Station (ISS) to grow crystals of human manganese superoxide dismutase (MnSOD)—an oxidoreductase critical for mitochondrial vitality and human health. The mission’s overarching aim is to perform neutron prote...

Single crystals of three Ce-doped rare earth oxyorthosilicates, Ln(SiO)O where Ln =Y, Gd, or Lu, were grown by the Czochralski technique. The formation of defects was strongly influenced by the crystal growth conditions for Ln = Gd but high quality boules for Ln = Y and Lu were grown...
Single crystal X-ray diffraction studies reveal the structures of the doped crystals to be tetragonal implying that the incorporation of the dopants has not changed the structure of the parent crystal. The diffraction planes were identified and indexed by powder diffraction analysis. High-resolution X...
