“…[337][338][339][340][341][342] In particular, one can fine-tune the energy gap in semiconducting materials by inducing lattice strain when amino acids, including also glycine, are incorporated into the host structure. [343,344] Selective interactions of glycine with the inorganic matrices are important also for the processes of biomineralization. [345,346]…”

Glycine is a small molecule. It cannot change its conformation and is achiral. Despite the apparent simplicity, glycine shows endless diversity in its behavior over many phenomena. It was the first amino acid for which polymorphism was reported, first on crystallization and then on hydrostatic compression. The polymorphs differ in their physical properties and their biological activity. Glycine clusters persist in solution, leading to "solution memory". Phenomena at interfaces are critically important for crystal growth, dissolution, and for physical properties, which can be at times unexpected, like polarity in centrosymmetric αpolymorph. It is a great pleasure to remind of these remarkable phenomena in a special issue honoring professors Meir Lahav and Leslie Leiserowitz, who pioneered the study of the behavior of this unique molecule in many respects, and showed how complex and non-trivial phenomena can be at interfaces: between phases and between research fields.

“…The peak shi was attributed to the incorporation of the amino acid, His, which caused slight lattice distortion in the crystal according to reported literature. [35][36][37] Moreover, the XRD peaks of His@ZIF-8/Tb 3+ remained unchanged when compared with those of His@ZIF-8. This may be due to the coordination of Tb 3+ with only the exposed carboxyl and amino groups of His@ZIF-8 without being incorporated into its framework.…”

“…The final lattice constants do not display any significant dependency on pyrophosphate concentration indicating that only slight macrostrain is inflicted upon the crystals even though very specific interactions take place. This is in contrast to the impact of organic additives on CaCO 3 biominerals [33][34][35][36][37], ZnO [38,39], and apatite [25].…”

Abstract:The pathways to crystals are still under debate, especially for materials relevant to biomineralization, such as calcium phosphate apatite known from bone and teeth. Pyrophosphate is widely used in biology to control apatite formation since it is a potent inhibitor of apatite crystallization. The impacts of pyrophosphate on apatite formation and crystallization kinetics are, however, not fully understood. Therefore, we studied apatite crystallization in water by synchrotron in situ X-ray diffraction. Crystallization was conducted from calcium chloride (0.2 M) and sodium phosphate (0.12 M) at pH 12 where hydrogen phosphate is the dominant phosphate species and at 60 • C to allow the synchrotron measurements to be conducted in a timely fashion. Following the formation of an initial amorphous phase, needle shaped crystals formed that had an octacalcium phosphate-like composition, but were too small to display the full 3D periodic structure of octacalcium phosphate. At later growth stages the crystals became apatitic, as revealed by changes in the lattice constant and calcium content. Pyrophosphate strongly inhibited nucleation of apatite and increased the onset of crystallization from minute to hour time scales. Pyrophosphate also reduced the rate of growth. Furthermore, when the pyrophosphate concentration exceeded~1% of the calcium concentration, the resultant crystals had reduced size anisotropy suggesting that pyrophosphate interacts in a site-specific manner with the formation of apatite crystals.

Bio-inspired engineering of a zinc oxide/amino acid composite: synchrotron microstructure study

Abstract: The presence of intracrystalline molecules has been shown to produce strains in synthetic ZnO crystals and alter the microstructure. These structural distinctions are accompanied by alteration of the band-gap of the semiconductor host.
