“…The misfit between the seed and grown crystals can cause dislocation nucleation. On the other hand, the spiral growth mode of biological protein crystals has been deliberately generated from the 2D growth mode via femtosecond laser ablation (Tominaga et al, 2016). Although the typical dislocations in our research are not exactly screw dislocations, the spiral growth mode can be generated by the crystal itself using cross-linked seed crystals.…”

X-ray topography is a useful and nondestructive method for direct observation of crystal defects in nearly perfect single crystals. The grown-in dislocations from the cross-linked seed crystal in tetragonal hen egg-white lysozyme crystals were successfully characterized by digital X-ray topography. Digital X-ray topographs with various reflections were easily obtained by reconstruction of sequential rocking-curve images. The Burgers vector of the dislocation is different from those reported previously. Interestingly, one of the dislocations had a bent shape. The preferred direction of the dislocation line was analysed by the estimated dislocation energy based on the dislocation theory. The dislocation energy can be estimated by the dislocation theory even in protein crystals composed of macromolecules.

“…A growth technique mediated by screw dislocations under low supersaturation has also been proposed [29][30][31][32]. Techniques in which an electric field is applied to a protein solution have also been actively investigated, with a focus on controlling the nucleation rate [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49].…”

Effect of an External Electric Field on the Kinetics of Dislocation-Free Growth of Tetragonal Hen Egg White Lysozyme Crystals

Dislocation-free tetragonal hen egg white (HEW) lysozyme crystals were grown from a seed crystal in a cell. The rates of tetragonal HEW lysozyme crystal growth normal to the (110) and (101) faces with and without a 1-MHz external electric field were measured. A decrease in the typical growth rates of the crystal measured under an applied field at 1 MHz was observed, although the overall driving force increased. Assuming that the birth and spread mechanism of two-dimensional nucleation occurs, an increase in the effective surface energy of the step ends was realized in the presence of the electric field, which led to an improvement in the crystal quality of the tetragonal HEW lysozyme crystals. This article also discusses the increase in the effective surface energy of the step ends with respect to the change in the entropy of the solid.

“…17 Light-induced nucleation provides an attractive approach to nucleating and crystallizing multielement materials in solutions with a high spatiotemporal control. 18 Liquid-phase laser synthesis requires no surfactants, leading to ligand-free NPs. 17,19,20 Here, we exploit the integration of accumulation-mediated concentration and laser-induced nucleation to enable the simultaneous synthesis and structuring of metallic alloys.…”

The concept of accumulation-mediated concentration is translated to the nano-/ microscale to achieve in situ unified synthesis and structuring of immiscible nanoalloys. The confinement effect, high fluid flow, and site-specific heating at a laser-induced microbubble trap (MBT) results in one-shot RhAu alloying and structuring. Random walk simulations reveal enhanced millisecond-timescale concentration of ions in the MBT. The synthesized and structured RhAu nanoalloys demonstrate enhanced catalytic activity. Our generic strategy can be easily scaled up toward various catalytic and optoelectronic applications.
