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

EMERGENT PROPERTIES. “Mesocrystals from functional materials are highly attractive due to the emergent properties of mesocrystalline materials, such as single crystal-like behavior, high crystallinity, high porosity and inner connection bridged by organic components and/or inorganic nanocrystals. Such property combinations in a single material are unrivalled compared to amorphous, polycrystalline, and single-crystalline materials.” https://lnkd.in/eNACsghr View in LinkedIn

ARTIFICIAL LINE. “There is no such thing as life! There are interesting chemical reactions, like Stephen Hawking, and less interesting chemical reactions like salt crystals...There is no line, no ‘breath of life’ separating living from nonliving. That is a metaphysical bit of silliness. We should focus on interesting over boring chemical reactions and forget about this line that does not exist except in our own minds.” (The famous quantum physicist, Jonathan P. Dowling (2013), Page 430). https://lnkd.in/eWbBjM7i View in LinkedIn

HYPERBOLAE. “The overall pattern described (not focussing on details near the slits) is one of hyperbolae, since the maxima and/or minima follow lines of constant length difference to the two foci, embodied by either the edges of the one slit, or by the two slits.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

DIFFRACTION GRATING. “In a relative geometry setting, these lines describe how particles on average are guided through space, setting a notion of what straight propagation means on a particle level, in relation to the apertures, which are obstacles to information exchange.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

TOOTH ENAMEL. “HAP is another biomineral, which was recently reported to form mesocrystals in tooth enamel-like structures and dentin remineralization suggesting a role of mesocrystals in calcium phosphate biominerals too.” https://lnkd.in/eNACsghr View in LinkedIn
