Nicholas Abbott, a University Professor of Chemistry at Cornell University, who also was not involved in this work, says 'The paper describes a very clever advance in interfacial charge storage, elegantly demonstrating how knowledge of molecular self-assembly at interfaces can be leveraged to address a contemporary technological challenge.'
The Liedl group is interested in molecular self-assembly and nanoengineering, in particular using the DNA origami method, to investigate biomolecular systems at high levels of control.

From the large scale to the micro-scale, from terra-forming to bio-manufacturing, this book presents the emerging discipline of ecological and sustainable design and architecture, touching on areas such as geo-engineering, low-energy fabrication, up-cycling waste, minimally invasive design, biomaterials, and molecular self-assembly. The introduction addresses the need for design for a planet in peril and gives a brief history of sustainable and ecological design.

Although very different in their head group chemistry, many natural as well as synthetic amphiphilic compounds derived from carbohydrates, carbocyanine dyes, or amino acids tend to form twisted fibrous structures by molecular self-assembly in water predominantly [12-15].
That curiosity has led him to make important discoveries on the nature of molecular self-assembly that have promising medical and industrial applications.
Sleiman was at Stanford University in the late 1980s completing her PhD in organic chemistry when she attended a lecture by Lehn on supramolecular chemistry--a discipline that examines the noncovalent interactions between molecules, from molecular self-assembly to molecular recognition.
It can monitor rapid internal materials changes, such as molecular self-assembly. Researchers can gain further information on temperature effects and relative humidity with the use of add-on modules; multiple x-ray source and double beamline options expand the instrument's scope.
Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to investigationg whether we can directly control matter on the atomic scale.
They are also not as near to each other and significantly less precisely shaped as with the "bottom-up" technique based on molecular self-assembly developed by the Empa and Max Planck group.
Nanotechnology is a highly diverse and multidisciplinary field, ranging from novel extensions of conventional device physics to the development of new materials with dimensions on the nanoscale, and completely new approaches based on molecular self-assembly.
