Confining a smectic liquid crystal between two spherical surfaces results in the formation of a complex defect structure characterized by a set of curvature walls that divide the sphere into crescent domains, causing the undulation of the smectic layers. In this paper, we examine in detail these smectic textures and discuss the various possible origins

Shell-in-Shell (SiS): 3D Shell Resonator with 3D Conformal Shell Electrodes
2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL), 2020This paper reports the design, fabrication technology and initial testing results of an all fused-silica 3D shell (hemispherical) resonator and capacitive drive/sense electrodes made from a second shell, for use in high-performance gyroscopes. A single fused-silica shell is patterned to form multiple electrodes that follow the curvature of the shell ...

Bacterial microcompartments (BMCs) are self-assembling organelles composed entirely of protein. Depending on the enzymes they encapsulate, BMCs function in either inorganic carbon fixation (carboxysomes) or organic carbon utilization (metabolosomes).

In his contributions to the monographic series "Manual of Conchology", Henry Pilsbry reviewed the subgroup Tectibranchiata, comprising those opisthobranch snails that (at least primitively) still possess a shell (Pilsbry, 1894-1896). Exemplified by the Cephalaspidea (bubble shells), others included in this group at Pilsbry's time and since were ...

Core–Shell–Shell and Hollow Double‐Shell Microgels with Advanced Temperature Responsiveness
Macromolecular Rapid Communications, 2014Unique doubly temperature‐responsive hollow microgels are presented. These consist of two concentric thermoresponsive polymer shells made of poly(N‐isopropylacrylamide) (PNIPAM) and poly(N‐isopropylmethacrylamide) (PNIPMAM), respectively. The hollow particles are derived from silica‐PNIPAM‐PNIPMAM core‐shell–shell (CSS) particles by dissolution of the ...

Australian Archaeology, 1992
Distinguishing natural accumulations of shell from Aboriginal shell middens is a problem often faced by archaeologists working in coastal regions (Attenbrow 1984; Ceci 1984; Dortch 1991; McBryde 1973; Statham 1892). I recently investigated two buried layers of shell which their discoverers thought could be Aboriginal shell middens.
