“…Since both crystals in the doublet grow independently in opposite directions from the central intravesicular band, this is most likely the site of the initial nucleation of the nanoscopic granules from the disordered precursor. As crystallization proceeds, welldefined platelets form, presumably from oriented attachment of these granules [39,41,45,46] (Figure 5(II)). At this stage, periodicity within the H-bonded bc plane emerges, but there is significant disorder arising from stacking faults and twinning.…”

Spectacular colors and visual phenomena in animals are produced by light interference from highly reflective guanine crystals. Little is known about how organisms regulate crystal morphology to tune the optics of these systems. By following guanine crystal formation in developing spiders, a crystallization mechanism is elucidated. Guanine crystallization is a “non‐classical,” multistep process involving a progressive ordering of states. Crystallization begins with nucleation of partially ordered nanogranules from a disordered precursor phase. Growth proceeds by orientated attachment of the nanogranules into platelets which coalesce into single crystals, via progressive relaxation of structural defects. Despite their prismatic morphology, the platelet texture is retained in the final crystals, which are composites of crystal lamellae and interlamellar sheets. Interactions between the macromolecular sheets and the planar face of guanine appear to direct nucleation, favoring platelet formation. These findings provide insights on how organisms control the morphology and optical properties of molecular crystals.

“…OA and, more generally, particle-mediated growth of single crystals, has now been widely observed in semiconductors, ,,, metals, ,, silicates, , oxides, ,,,,,− carbonates, , fluorides, organic compounds, peptides, and proteins . Many styles of particle-mediated growth that result in single crystal products have been observed since the first report of OA, including: (1) attachment with crystallographic coalignment prior to coalescence, ,, (2) attachment with some degree of misalignment, followed by relaxation through atomistic processes into a coaligned state, , (3) attachment of metastable particles of a nanoscopic phase onto crystals of the bulk phase, followed by transformation, ,,, and (4) a special class of no. 3 in which the nanoscopic phase is amorphous. ,, …”

Interfacial reactions drive all elemental cycling on Earth and play pivotal roles in human activities such as agriculture, water purification, energy production and storage, environmental contaminant remediation, and nuclear waste repository management. The onset of the 21st century marked the beginning of a more detailed understanding of mineral aqueous interfaces enabled by advances in techniques that use tunable high-flux focused ultrafast laser and X-ray sources to provide near-atomic measurement resolution, as well as by nanofabrication approaches that enable transmission electron microscopy in a liquid cell. This leap into atomic-and nanometer-scale measurements has uncovered scale-dependent phenomena whose reaction thermodynamics, kinetics, and pathways deviate from previous observations made on larger systems. A second key advance is new experimental evidence for what scientists hypothesized but could not test previously, namely, interfacial chemical reactions are frequently driven by "anomalies" or "non-idealities" such as defects, nanoconfinement, and other nontypical chemical structures. Third, progress in computational chemistry has yielded new insights that allow a move beyond simple schematics, leading to a molecular model of these complex interfaces. In combination with surfacesensitive measurements, we have gained knowledge of the interfacial structure and dynamics, including the underlying solid surface and the immediately adjacent water and aqueous ions, enabling a better definition of what constitutes the oxide− and silicate−water interfaces. This critical review discusses how science progresses from understanding ideal solid−water interfaces to more realistic systems, focusing on accomplishments in the last 20 years and identifying challenges and future opportunities for the community to address. We anticipate that the next 20 years will focus on understanding and predicting dynamic transient and reactive structures over greater spatial and temporal ranges as well as systems of greater structural and chemical complexity. Closer collaborations of theoretical and experimental experts across disciplines will continue to be critical to achieving this great aspiration.

“…In the early development stage (stage I) (Figure a–c), the middle part of the vesicle can be observed with a clear and definite intravesicular band (Figure a, dashed blue line), the two sides of which are partially ordered noncrystalline guanine granules. In the intermediate development stage (stage II) (Figure d–f), the guanine crystal platelets gradually form from both ends of the intravesicular band toward the center in the direction of hydrogen bonds, probably because of the directed attachment of nanoscopic granules. , In the late development stage (stage III) (Figure g–i), stacked crystal platelets that are slightly misaligned are formed along the π-stacking direction (between hydrogen bonding layers). The remainder is filled with guanine particles, the number of which decreases with increasing proximity to the central intravesicular band.…”
