Abstract:
Colloidal assembly into chiral superstructures is usually accomplished with templating or lithographic patterning methods that are only applicable to materials with specific compositions and morphologies over narrow size ranges. Here, chiral superstructures can be rapidly formed by magnetically assembling materials of any chemical compositions at all scales, from molecules to nano- and microstructures. We show that a quadrupole field chirality is generated by permanent magnets caused by consistent field rotation in space. Applying the chiral field to magnetic nanoparticles produces long-range

Abstract:
By means of coarse-grained molecular dynamics simulations, we explore chiral sensitivity of confining spaces modelled as helical channels to chiral superstructures represented by polymer knots. The simulations show that helical channels exhibit stereosensitivity to chiral knots localized on linear chains by effect of external pulling force and also to knots embedded on circular chains. The magnitude of the stereoselective effect is stronger for torus knots, the effect is weaker in the case of twist knots, and amphichiral knots do exhibit no chiral effects. The magnitude of the effect can be tu

Abstract:
Biomolecular hydration is fundamental to biological functions. Using phase-resolved chiral sum-frequency generation spectroscopy (SFG), we probe molecular architectures and interactions of water molecules around a self-assembling antiparallel β-sheet protein. We find that the phase of the chiroptical response from the O-H stretching vibrational modes of water flips with the absolute chirality of the (l-) or (d-) antiparallel β-sheet. Therefore, we can conclude that the (d-) antiparallel β-sheet organizes water solvent into a chiral supermolecular structure with opposite handedness relative to

Global Radio: From Shortwave to Streaming chronicles the development of radio as a global medium. In this book, Shaheed Nick Mohammed examines the evolution of radio from its early uses as little more than a novelty into a set of powerful systems for international exchanges of news, culture, and political influence. In doing so, the book follows the development of radio as a wireless form of the telegraph, its evolution into a medium for sound transmission across the air, and its adaptation to digital networked audio and transmissions technologies.

<p>During the urban development process in China, there is a growing demand for the construction of rail transit, leading to an increase in the number and size of depots allocated to corresponding lines. To enhance the efficiency of land resources, the strategic secondary use of depot-occupied land can help maximize economic and social benefits, as well as forming over-track buildings in metro depots. A typical feature of over-track buildings in metro depots is phased construction, where the superstructure development lags behind the substructure, requiring conditions adaptive for future

The longitudinal thermal movement of the superstructure is usually considered as the key parameter for designing jointless bridges. The average temperature of cross‐sections can be considered as the effective temperature of the superstructure. In order to accurately estimate the longitudinal thermal movement of the superstructure, the average temperature of cross‐sections should be obtained.

It has been proven that the seismic isolation technology is a very promising tool to lessen damage caused by earthquakes. In order to provide a cheap and efficient base isolator for engineering practice, a new isolator named the trench friction pendulum system (TFPS), which is easy to design and manufacture, is proposed in this study. A series of shaking table tests of a scaled steel structure equipped with TFPS isolators were performed in the Department of Civil Engineering, Feng Chia University, Taichung, Taiwan. Experimental results demonstrate that the TFPS isolator can isolate most of ear
