Engineering Bacterial Microcompartment Shells: Chimeric Shell Proteins and Chimeric Carboxysome Shells

ACS Synthetic Biology, 2014
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).

Open-shell extensions to closed-shell pCCD

Chemical Communications, 2021
The proposed inexpensive open-shell extensions of the closed-shell pCCD model facilitate an accurate description of open-shell molecules.

Shelled opisthobranchs

2002
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, 2014
Unique 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 ...

Shell Bed Or Shell Midden

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.

OFF-SHELL NILPOTENCY FOR ON-SHELL REDUCIBILITY

Modern Physics Letters A, 1992
The direct way of Lagrangian BRS gauge-fixing we proposed recently is applied to reducible gauge theories; antisymmetric tensor gauge theories are considered as definite examples. It enables us to do without ad hoc ghosts for ghosts. It also achieves BRS-exact forms of full gauge-fixing terms by means of off-shell nilpotent BRS transformations.

Closed-Shell and Open-Shell 2D Nanographenes

2012
This chapter describes a series of two-dimensional (2D) expanded arene networks, also known as nanographenes, with either closed-shell or open-shell electronic structure in the ground state. These systems are further categorized into three classes on a basis of different edge structures: those with zigzag edges only, those with armchair edges only, and

Core-Shell-Corona Micelles with a Responsive Shell

Angewandte Chemie International Edition, 2001
A reactor for the synthesis of gold nanoparticles is one of the uses of a poly(styrene)-block-poly(2-vinylpyridine)-block-poly(ethylene oxide) triblock copolymer (PS-b-P2VP-b-PEO) which forms core-shell-corona micelles in water. Very low polydispersity spherical micelles are observed that consist of a PS core surrounded by a pH-sensitive P2VP shell and

Shell Molding and Shell Coremaking

2008
Abstract Shell molding is used for making production quantities of castings that range in weight from a few ounces to approximately 180 kg (400 lb), in both ferrous and nonferrous metals. This article lists the limitations or disadvantages of shell mold casting. It describes the two methods for preparation of resin-sand mixture for shell
