Thermal fluctuations in the conical state of monoaxial helimagnets [PDF]

, 2018
The effect of thermal fluctuations on the phase structure of monoaxial helimagnets with external magnetic field parallel to the chiral axis is analyzed by means of a saddle point expansion of the free energy.

Phototunable Polarization Volume Gratings Driven by Chiral Hydrazone Switches

Advanced Optical Materials, EarlyView.
Chiral hydrazone photoswitches incorporated into polarization volume gratings enable light‐driven, reversible modulation of optical properties. UV and blue light irradiation reversibly alter the hydrazone isomer ratio, leading to tunable diffraction efficiency and spectral response across the visible spectrum.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Preparation of Poly-(GMA-EDA-β-CD-co-TMPTMA) Monolith as High Performance Liquid Chromatography Chiral Stationary Phase Column

Indonesian Journal of Chemistry, 2019
An enantiomer molecule consisted of the chiral atom has different structure conformations, which exhibit different activities as well. Yet, its separation considerably difficult since ordinary separation could not separate both molecules.

Monolithic UV‐Laser Programming of Photothermally Meta‐Morphing SMA Structures: Dual‐Encoded Kirigami Mechanics and Photonic Absorbance

Advanced Science, EarlyView.
A monolithic manufacturing strategy is presented for photothermal shape memory alloy (SMA) meta‐morphing structures. Using a single‐step UV‐laser process, the mechanical compliance is programmed via kirigami patterning while optical absorbance is simultaneously tuned through surface oxidation.
