text: Redox mediators could catalyse otherwise slow and energy-inefficient cycling
of Li–S and Li–O2 batteries by shuttling electrons or holes between the electrode
and the solid insulating storage materials. For mediators to work efficiently
they need to oxidize the solid with fast kinetics but with the lowest possible
overpotential. However, the dependence of kinetics and overpotential is unclear,
which hinders informed improvement. Here, we find that when the redox potentials
of mediators are tuned via, for example, Li+ concentration in the electrolyte,
they exhibit distinct threshold potentials, where the kinetics accelerate several-fold
within a range as small as 10 mV. This phenomenon is independent of types of mediator
and electrolyte. The acceleration originates from the overpotentials required
to activate fast Li+/e− extraction and the following chemical step at specific
abundant surface facets. Efficient redox catalysis at insulating solids therefore
requires careful consideration of the surface conditions of the storage materials
and electrolyte-dependent redox potentials, which may be tuned by salt concentrations
or solvents.

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: We report the observation of an anomalous nonlinear optical response of the
prototypical three-dimensional topological insulator bismuth selenide through
the process of high-order harmonic generation. We find that the generation efficiency
increases as the laser polarization is changed from linear to elliptical, and
it becomes maximum for circular polarization. With the aid of a microscopic theory
and a detailed analysis of the measured spectra, we reveal that such anomalous
enhancement encodes the characteristic topology of the band structure that originates
from the interplay of strong spin–orbit coupling and time-reversal symmetry protection.
The implications are in ultrafast probing of topological phase transitions, light-field
driven dissipationless electronics, and quantum computation.

text: Recent discoveries have shown that, when two layers of van der Waals (vdW)
materials are superimposed with a relative twist angle between them, the electronic
properties of the coupled system can be dramatically altered. Here, we demonstrate
that a similar concept can be extended to the optics realm, particularly to propagating
phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks
composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic
phonon polaritons (PhPs), and image the propagation of the latter when launched
by localized sources. Our images reveal that, under a critical angle, the PhPs
isofrequency curve undergoes a topological transition, in which the propagation
of PhPs is strongly guided (canalization regime) along predetermined directions
without geometric spreading. These results demonstrate a new degree of freedom
(twist angle) for controlling the propagation of polaritons at the nanoscale with
potential for nanoimaging, (bio)-sensing, or heat management.

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: Efficient isomerization of photochromic molecules often requires conformational
freedom and is typically not available under solvent-free conditions. Here, we
report a general methodology allowing for reversible switching of such molecules
on the surfaces of solid materials. Our method is based on dispersing photochromic
compounds within polysilsesquioxane nanowire networks (PNNs), which can be fabricated
as transparent, highly porous, micrometer-thick layers on various substrates.
We found that azobenzene switching within the PNNs proceeded unusually fast compared
with the same molecules in liquid solvents. Efficient isomerization of another
photochromic system, spiropyran, from a colorless to a colored form was used to
create reversible images in PNN-coated glass. The coloration reaction could be
induced with sunlight and is of interest for developing “smart” windows.

text: We demonstrate a method for manipulating small ensembles of vortices in multiply
connected superconducting structures. A micron-size magnetic particle attached
to the tip of a silicon cantilever is used to locally apply magnetic flux through
the superconducting structure. By scanning the tip over the surface of the device
and by utilizing the dynamical coupling between the vortices and the cantilever,
a high-resolution spatial map of the different vortex configurations is obtained.
Moving the tip to a particular location in the map stabilizes a distinct multivortex
configuration. Thus, the scanning of the tip over a particular trajectory in space
permits nontrivial operations to be performed, such as braiding of individual
vortices within a larger vortex ensemble—a key capability required by many proposals
for topological quantum computing.

text: 'The bacteriophage M13 has found frequent applications in nanobiotechnology
due to its chemically and genetically tunable protein surface and its ability
to self-assemble into colloidal membranes. Additionally, its single-stranded (ss)
genome is commonly used as scaffold for DNA origami. Despite the manifold uses
of M13, upstream production methods for phage and scaffold ssDNA are underexamined
with respect to future industrial usage. Here, the high-cell-density phage production
with Escherichia coli as host organism was studied in respect of medium composition,
infection time, multiplicity of infection, and specific growth rate. The specific
growth rate and the multiplicity of infection were identified as the crucial state
variables that influence phage amplification rate on one hand and the concentration
of produced ssDNA on the other hand. Using a growth rate of 0.15 h−1 and a multiplicity
of infection of 0.05 pfu cfu−1 in the fed-batch production process, the concentration
of pure isolated M13 ssDNA usable for scaffolded DNA origami could be enhanced
by 54% to 590 mg L−1. Thus, our results help enabling M13 production for industrial
uses in nanobiotechnology. Biotechnol. Bioeng. 2017;114: 777–784.'

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.

text: The reversible molecular template-directed self-assembly of gold nanoparticles
(AuNPs), a process which relies solely on noncovalent bonding interactions, has
been demonstrated by high-resolution transmission electron microscopy (HR-TEM).
By employing a well-known host−guest binding motif, the AuNPs have been systemized
into discrete dimers, trimers, and tetramers. These nanoparticulate twins, triplets,
and quadruplets, which can be disassembled and reassembled either chemically or
electrochemically, can be coalesced into larger, permanent polygonal structures
by thermal treatment using a focused HR-TEM electron beam.
