Also known as bivalves (two valves), the clam family contributes a lot
of shell material to the sea floor and beaches.
Acidifying the ocean is particularly detrimental to organisms that
secrete shell material made of CaCO3, such as coral reefs and a type of phytoplankton called coccolithophorids [Kleypas et al., 1999].
Neivandt and his team suggest that the
ground shell material can be used in other products such as biodegradable flower pots.
One possibility is that it minimises
the shell material needed for the same volume.
In most cases, a large lattice mismatch between core and
shell materials would prevent the formation of high - quality core - shell structures, but the technique overcomes that limitation.
For the numerical simulation, the researchers constructed a «phase - field» model, which mathematically defined the phase transitions of
the shell material.
«Our work is important because shell - thickness is most often a crucial parameter in applications where core -
shell materials can be used to enhance performance of future materials.»
The core is dissolved using a solvent, demonstrating the technology's capability to fully separate core and
shell materials (scale 25 microns).
I would have preferred a more substantial weight for
the shell material, the finish is great, but a bit more «heft» seems appropriate given the appearance.
The shell material is water resistant machine washable and it comes with a convenient hideaway storage bag so owners can simply fold and go when done.
Re: inside vs outside of the shell: your analysis is only true if
the shell material is thermally saturated.
