Spontaneous ordering of self‐assembled‐Ge island

Crystal Research and Technology, 2005
AbstractSelf‐assembled quantum dots can be the building blocks of a variety of mesoscopic devices. However, in order to use these structures in large‐scale integrated devices, accurate control over their spatial positioning is required. We show here that, by a suitable engineering of the deposition process, it is possible to obtain self‐organization ...

Spontaneous assembly of viruses on multilayered polymer surfaces

Nature Materials, 2006
The idea that randomly arranged supermolecular species incorporated in a network medium can ultimately create ordered structures at the surface may be counterintuitive. However, such order can be accommodated by regulating dynamic and equilibrium driving forces.

Spontaneous Chiral Self-Assembly of CdSe@CdS Nanorods

SSRN Electronic Journal, 2021
Summary The enantiomeric excess phenomenon in spontaneous chiral symmetry breaking (SCSB) is a crucial issue in the origin of homochirality in nature, whereas chiral inorganic compounds have long been reckoned as racemates. Here, we report the SCSB in the self-assembly of cadmium chalcogenide nanorods, leading to chiral biases away from the racemate.

Spontaneous assembly of ordered nanoclusters and nanowires

Surface and Interface Analysis, 2004
Abstract A novel strategy for the spontaneous formation of spatially ordered nanoclusters and nanowires by taking advantage of templates is reported. With this method, a large‐scale perfectly ordered identical‐size indium nanocluster array and ordered indium nanowire array are obtained on Si(111)‐(7 × 7) and Si ...

Spontaneous Assembly of Magnetic LEGO Bricks

The Chemical Educator, 2001
This paper describes simple methods of demonstrating macroscale spontaneous assembly. These demonstrations can illustrate topics in college or high school chemistry courses, such as the thermodynamics of crystallization and the chelate effect. The assembling units are built from a combination of magnetic and conventional LEGO building blocks.

Spontaneous template-free assembly of ordered macroporous titania

Chemical Communications, 2004
Spontaneous formation of ordered macroporous titania is achieved by dropwise addition of titanium alkoxides to aqueous ammonia in the absence of auxiliary organic templates.

Spontaneous symmetry breaking of semiconductor nanorods and assemblies

Chem, 2021
In this issue of Chem, Che and co-workers assessed the formation of the helical structure of CdS@CdSe nanorods without the use of chiral reagents. Spontaneous chiral symmetry breaking occurred in the chiral CdSe@CdS nanorod assemblies, which was probably caused by the majority rule.

Peptide spontaneously assembles into membrane

Chemical & Engineering News Archive, 1993
A 16-residue peptide has been found to spontaneously assemble into a visible, insoluble membrane—a phenomenon that could have implications for neurological, biomaterials, and origin-of-life studies. The discovery was made by biologists Shuguang Zhang, Todd Holmes, Curtis Lockshin, and Alexander Rich at Massachusetts Institute of Technology [ Proc. Natl.

A Card Trick Using Spontaneous Assembly

The Chemical Educator, 2007
A demonstration of spontaneous organization (or “self-assembly”) of wetted flat plates is described. The organization process itself involves the plates rotating over each other to achieve the same orientation and varies with the size, shape, and composition of the plates, and the properties of the liquid wetting the surface of the plates.
