Shell thickness refers to the measurement or amount of material that forms the outer layer of an object, like a shell. It indicates how thick or thin that layer is.
Full definition
The gene that
controls shell thickness, creatively named SHELL, was identified in 2013 by researchers at Orion, Cold Spring Harbor Laboratory in New York and the Malaysian Palm Oil Board (MPOB), a government research institute based near Kuala Lumpur.
Varying
the shell thickness changed the spacing of the particles when they aggregated into supraballs.
For different applications, it is important to be able to control
the shell thicknesses.
To observe this growth phenomenon, the NRL team grew alumina on nano - and micron - sized particles of tungsten and measured
the shell thickness in a transmission electron microscope.
