GEOMETRY. “Lastly, the present analysis is of static relative geometries for simplicity, and generic relative geometries must include time dependence. With changes in geometry consistent with approximately flat space-time, causality should limit the propagation of the subsequent effects (classical or quantum).” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

KICKING IT DOWN THE ROAD. “Therefore polarization concerns, relating to characteristics of information without impact on most particles, are not among the most pressing matters at hand, and are deferred until a later point.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

COMPLEX CONCEPT. “With a scenario building on information exchange, however, properties directly connected to information propagation (such as light) turn into defining qualities (in this case of space-time) rather than limitations on what is physical.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

THE NUMBERS. “The 3000-fold fracture toughness of nacre was explained by energy dissipation by the polymeric layers.” https://lnkd.in/eNACsghr View in LinkedIn

GREATER THAN THE SUM. “The brittle crystals can add mechanical strength and hardness to the system while the soft polymeric or amorphous phase is deformable and adds elasticity.” https://lnkd.in/eNACsghr View in LinkedIn

GREATER STRENGTH BIOMINERALS. “Compared to a single crystal with cleavage planes, which makes it very brittle, the polycrystal-line mesocrystal structure with soft regions between the singe crystalline nanoparticle building units can make the hybrid material superiour to its constituents.” https://lnkd.in/eNACsghr View in LinkedIn

BIOMINERAL MESOCRYSTALS. “An important recent finding is that several Biominerals turned out to be mesocrystals like sea urchin spines, sponge spicules, foraminifera, nacre, calcite prisms in mussel shells,corals, or egg shells, as summarized by Oaki et al. and for calcareous sponge spicules.” https://lnkd.in/eNACsghr View in LinkedIn

ALCHEMY. “Once a mesocrystal is formed, it can be transformed to a mesocrystal of another mineral system by topotactic conversion under favorable conditions. The term topotaxy (Greek; "topos" = "space" and "taxis" = "in ordered manner") describes all solid state reactions that lead to a material with crystal orientations, which are correlated with crystal orientations in the initial product.” https://lnkd.in/eNACsghr View in LinkedIn

MINIMAL ENERGY STATES. “The driving force for the geometrical alignment is the minimization of the interface mismatch energy by forming a coherent interface and reducing the exposed surface area while edge sharing is promoted by reduction of the amount of dangling unsaturated bonds along the edge, which have an inherently high chemical energy.” https://lnkd.in/eNACsghr View in LinkedIn
