text: Optoelectronic effects differentiating absorption of right and left circularly
polarized photons in thin films of chiral materials are typically prohibitively
small for their direct photocurrent observation. Chiral metasurfaces increase
the electronic sensitivity to circular polarization, but their out-of-plane architecture
entails manufacturing and performance trade-offs. Here, we show that nanoporous
thin films of chiral nanoparticles enable high sensitivity to circular polarization
due to light-induced polarization-dependent ion accumulation at nanoparticle interfaces.
Self-assembled multilayers of gold nanoparticles modified with L-phenylalanine
generate a photocurrent under right-handed circularly polarized light as high
as 2.41 times higher than under left-handed circularly polarized light. The strong
plasmonic coupling between the multiple nanoparticles producing planar chiroplasmonic
modes facilitates the ejection of electrons, whose entrapment at the membrane–electrolyte
interface is promoted by a thick layer of enantiopure phenylalanine. Demonstrated
detection of light ellipticity with equal sensitivity at all incident angles mimics
phenomenological aspects of polarization vision in marine animals. The simplicity
of self-assembly and sensitivity of polarization detection found in optoionic
membranes opens the door to a family of miniaturized fluidic devices for chiral
photonics.

text: Confining molecules can fundamentally change their chemical and physical properties.
Confinement effects are considered instrumental at various stages of the origins
of life, and life continues to rely on layers of compartmentalization to maintain
an out-of-equilibrium state and efficiently synthesize complex biomolecules under
mild conditions. As interest in synthetic confined systems grows, we are realizing
that the principles governing reactivity under confinement are the same in abiological
systems as they are in nature. In this Review, we categorize the ways in which
nanoconfinement effects impact chemical reactivity in synthetic systems. Under
nanoconfinement, chemical properties can be modulated to increase reaction rates,
enhance selectivity and stabilize reactive species. Confinement effects also lead
to changes in physical properties. The fluorescence of light emitters, the colours
of dyes and electronic communication between electroactive species can all be
tuned under confinement. Within each of these categories, we elucidate design
principles and strategies that are widely applicable across a range of confined
systems, specifically highlighting examples of different nanocompartments that
influence reactivity in similar ways.

text: Recent technical developments in the fields of quantum electromechanics and
optomechanics have spawned nanoscale mechanical transducers with the sensitivity
to measure mechanical displacements at the femtometre scale and the ability to
convert electromagnetic signals at the single photon level. A key challenge in
this field is obtaining strong coupling between motion and electromagnetic fields
without adding additional decoherence. Here we present an electromechanical transducer
that integrates a high-frequency (0.42 GHz) hypersonic phononic crystal with a
superconducting microwave circuit. The use of a phononic bandgap crystal enables
quantum-level transduction of hypersonic mechanical motion and concurrently eliminates
decoherence caused by acoustic radiation. Devices with hypersonic mechanical frequencies
provide a natural pathway for integration with Josephson junction quantum circuits,
a leading quantum computing technology, and nanophotonic systems capable of optical
networking and distributing quantum information.

text: The chemical behaviour of molecules can be significantly modified by confinement
to volumes comparable to the dimensions of the molecules. Although such confined
spaces can be found in various nanostructured materials, such as zeolites, nanoporous
organic frameworks and colloidal nanocrystal assemblies, the slow diffusion of
molecules in and out of these materials has greatly hampered studying the effect
of confinement on their physicochemical properties. Here, we show that this diffusion
limitation can be overcome by reversibly creating and destroying confined environments
by means of ultraviolet and visible light irradiation. We use colloidal nanocrystals
functionalized with light-responsive ligands that readily self-assemble and trap
various molecules from the surrounding bulk solution. Once trapped, these molecules
can undergo chemical reactions with increased rates and with stereoselectivities
significantly different from those in bulk solution. Illumination with visible
light disassembles these nanoflasks, releasing the product in solution and thereby
establishes a catalytic cycle. These dynamic nanoflasks can be useful for studying
chemical reactivities in confined environments and for synthesizing molecules
that are otherwise hard to achieve in bulk solution.
