Coupled Ferroelectricity and Optical Activity in Optically Active Ferroelectrics
The Journal of Physical Chemistry LettersFerroelectricity was initially discovered in 1921 in Rochelle salt (potassium sodium tartrate tetrahydrate), a chiral compound containing a chiral unit. However, the inherent relationship between coupled ferroelectricity and optical activity in chiral ferroelectrics derived from achiral units, as well as in polar ferroelectrics, remains insufficiently ...

Simple pictorial arguments can demonstrate that the natural and Faraday rotation experiments conserve parity and time-reversal invariance. The method can be used to predict possible new effects without recourse to mathematical theories.

Immersion-Triggered Active Switch for Spin-Decoupled Meta-Optics Multi-Display.
Small, 2022Meta-optics exhibits many promising applications in various fields of optical displays, imaging, and information encryption. However, heading towards next-generation intelligent displays, its broad implementation is critically restricted by the lack of ...

HYPATIA and STOIC: an active optics system for a large space telescope
Astronomical Telescopes + Instrumentation, 2016The next generation of UVOIR space telescopes will be required to provide excellent wavefront control despite perturbations due to thermal changes, gravity release and vibrations.

Active optics system for the 4m telescope of the Eastern Anatolia Observatory (DAG)
Astronomical Telescopes + Instrumentation, 2016An active optics system is being developed by AMOS for the new 4m-class telescope for the Turkish Eastern Anatolia Observatory (DAG). It consists in (a) an adjustable support for the primary mirror and (b) two hexapods supporting M2 and M3.

The GMT active optics control strategies
Astronomical Telescopes + Instrumentation, 2016The Giant Magellan Telescope (GMT) has a Gregorian 25.4-meter diameter primary mirror composed of seven 8.4-meter diameter segments. The secondary mirror consists of seven 1.1-meter diameter segments. In the active and adaptive operation modes of the GMT,

Experiments on the Origins of Optical Activity
Origins of Life, 1974Two recent reports claim that (1) aqueous L-aspartic acid polymerizes faster than D-Asp in the presence of kaolin at 90 degrees, and (2) L-phenylalanine is adsorbed by kaolin more extensively than D-Phe at pH 4(the reverse being true at pH2). The novelty of these observations and their potential significance for the origin of optical activity has ...

Optical control of antibacterial activity
Nature Chemistry, 2013Bacterial resistance is a major problem in the modern world, stemming in part from the build-up of antibiotics in the environment. Novel molecular approaches that enable an externally triggered increase in antibiotic activity with high spatiotemporal resolution and auto-inactivation are highly desirable.
