23 hours ago · The high quality mixed crystal with near stoichiometric Lu 0.5 Gd 0.5 VO 4 has been grown successfully by the Czochralski method. The composition, structure and thermal properties were studied. First, the growth conditions and crystal quality were analyzed.
5 days ago · The crystal lattice and the unit cell are the three-dimensional, repeating structure of points that turn into the atomic, ionic, or molecular positions of atoms in a crystal. Such a structured pattern extends throughout, giving a unique and orderly structure to the material.
1 day ago · Tellurium is a chemical element; it has symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in its native form as elemental crystals.
2 days ago · Due to the large number of ice crystals obtained, only a small number of ice crystals, typically the largest 4 to 25 ice crystals in each image, are selected, and the single largest length along any axis for each crystal is used to calculate the mean largest grain size (MLGS) from two or three wafers (Biggs, et al., 2019). The percentage largest grain size (%MLGS) is calculated by dividing the ...
5 days ago · Since π-conjugated molecules are commonly used as a scaffold for constructing optoelectronic and functional materials, much effort has been devoted to exploring novel molecular scaffolds for obtaining superior properties. This study focuses on dinuclear hypervalent tin(iv) compounds prepared by the ladderization of
