Article Synopsis
- The study focuses on how dislocation-mediated stress relaxation in crystal growth differs when growing calcite (CaCO3) on organic self-assembled monolayers, as opposed to inorganic heterostructures.
- It uses Bragg coherent diffraction imaging to visualize the crystal structure and internal strain of calcite, revealing a consistent presence of a single dislocation loop in each crystal.
- The findings suggest that these dislocation loops have unique geometries influenced by interfacial defects and substrate roughness, highlighting significant differences in crystal growth behavior on organic versus inorganic substrates.
Article Synopsis
- Research on using combinations of organic additives for controlling crystallization, similar to biomineralization, is underexplored because of the large number of potential reactions.
- This study shows that applying combinatorial methods guided by genetic algorithms can effectively discover active combinations of additives.
- Four important organic molecules are quickly identified that create highly fluorescent CdS quantum dot superstructures.
Phase diagram and structure-property relationships in the lead-free piezoelectric system: Na0.5K0.5NbO3-LiTaO3.
IEEE Trans Ultrason Ferroelectr Freq Control
September 2011
A phase-diagram for the Na(0.5)K(0.5)NbO(3)-LiTaO(3) solid solution series (NKN-LT) is presented for compositions ≤ 10 mol% LT, based on the combined results of temperaturevariable X-ray powder diffraction and dielectric measurements.
