MINERAL BRIDGES. “An assembly of mineral bridge connected crystals is in fact also a single crystal. Thus, this concept is the most straightforward one among the mesocrystal formation mechanisms to explain the mutual crystallographic orientation of the nanocrystal.” https://lnkd.in/eNACsghr View in LinkedIn

SOLVENT ACTIONS. “Release of surface hydration water or attached surfactant molecules can yield an additional entropic driving force besides the energy gain through elimination of two high energy surfaces. This would transform the mesocrystal into a single crystal.” https://lnkd.in/eNACsghr View in LinkedIn

INTRAMOLECULAR FORCES. “Beside physical fields with longer range, there are also forces upon particle contact. Already two identical crystal faces can orient each other when brought in close contact, as was observed in the process of oriented aggregation. The principal attractive force between two objects is the van der Waals attraction, which can lead to aggregation of particles.” https://lnkd.in/eNACsghr View in LinkedIn

FRAGMENT FROM NATURE this weekend continues from last weekend and concludes on Sunday on the theme of mesocrystals in biomaterials. Both mesocrystals and biominerals are outliers in their unusual physical properties, and chemists have been trying to understand biomineralization in order to advance biomimicry chemistry to create advanced materials with enhanced properties. https://lnkd.in/eNACsghr View in LinkedIn

LIGHT ANALOGY. “The conclusion from this merely is that it likely is possible to fashion a structure within flat space-time and endow particle interactions with overall properties in relation to it, with an end result in rough agreement with light diffraction.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

STRIKING ANALOGIES. “It is remarkable that the structural levels found for biopolymers such as proteins or polysaccharides have similar features as the structural levels found in a mesocrystal. Both structures rely on self organization/structuration processes in a solvent and it is useful to consider analogies.” https://lnkd.in/eNACsghr View in LinkedIn

BUCKMINSTER. “The upshot of the above is that through the symmetry, it is possible to identify a flat geometry where hyperbolae are geodesics.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

SCALAR ASSUMPTION. “However, we will assume a decent separation of scales between the various effects, so that the different structures can be considered to be nested within each other and dealt with separately.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

NESTED PROPERTIES. “The full symmetry picture is quite intricate, since the configuration of the obstacles have nested geometrical qualities. For a double-slit, there are single slits at the foci, and for a single slit, there are edges at the foci. In addition, an elliptic transformation does not give a diffeomorphism for the line between the foci.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

THE JOINT. “A large part of the appropriate geometry hence is elliptic, and we will illustrate that the elliptic geometry is compatible with a flat space-time metric that seamlessly connects to the vacuum flat metric far away from the apertures.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn
