An external shell of 181Ta would be irradiated by the intensive high-energy neutron flux from a hypothetical exploding nuclear weapon.
Mr. Shaw, of Purdue, said that he and many of his counterparts had accepted that the external shells of their systems must remain somewhat porous.
The external shells of gastropods and bivalve mollusks (e.g., clams, scallops) are calcareous, stiff, and almost detached from the body.
Thus, it is possible to probe separately the electrical properties of internal and external shells of MWCNT.
Surface-burrowing species may have an external shell sculpture of radial ribs and concentric lines, with projections that strengthen the shell against predators and damage.
The implant core is made of titanium (TiAl6V4) alloy, whereas the external shell is composed of commercially pure titanium.
Both internal and external shell dimensions, patterns of shell growth, shell strength and hinge characteristics, characteristics of oysters meats, and other data are reported.
Furthermore, a recent interesting, if speculative, proposal suggests that, when driven by an external source of energy, matter will rearrange itself to dissipate this energy most efficiently.
The evolution of external shells in the Late Ediacaran is thought to be a defence against predators, marking the start of an evolutionary arms race.
The evolutionary success of the molluscs can in part be attributed to the evolvability of the external shell.
For core shell structure particles, one of the two metals constitutes the core of the structure, and the other one the external shell, the SPR become complex because of the interface between core and shell.
