text: The short history of research on Li-O2 batteries has seen a remarkable number
of mechanistic U-turns over the years. From the initial use of carbonate electrolytes,
that were then found to be entirely unsuitable, to the belief that (su)peroxide
was solely responsible for degradation, before the more reactive singlet oxygen
was found to form, to the hypothesis that capacity depends on a competing surface/solution
mechanism before a practically exclusive solution mechanism was identified. Herein,
we argue for an ever-fresh look at the reported data without bias towards supposedly
established explanations. We explain how the latest findings on rate and capacity
limits, as well as the origin of side reactions, are connected via the disproportionation
(DISP) step in the (dis)charge mechanism. Therefrom, directions emerge for the
design of electrolytes and mediators on how to suppress side reactions and to
enable high rate and high reversible capacity.

text: The power factor of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)
(PEDOT:PSS) film can be significantly improved by optimizing the oxidation level
of the film in oxidation and reduction processes. However, precise control over
the oxidation and reduction effects in PEDOT:PSS remains a challenge, which greatly
sacrifices both S and σ. Here, we propose a two-step post-treatment using a mixture
of ethylene glycol (EG) and Arginine (Arg) and sulfuric acid (H2SO4) in sequence
to engineer high-performance PEDOT:PSS thermoelectric films. The high-polarity
EG dopant removes the excess non-ionized PSS and induces benzenoid-to-quinoid
conformational change in the PEDOT:PSS films. In particular, basic amino acid
Arg tunes the oxidation level of PEDOT:PSS and prevents the films from over-oxidation
during H2SO4 post-treatment, leading to increased S. The following H2SO4 post-treatment
further induces highly orientated lamellar stacking microstructures to increase
σ, yielding a maximum power factor of 170.6 μW m−1 K−2 at 460 K. Moreover, a novel
trigonal-shape thermoelectric device is designed and assembled by the as-prepared
PEDOT:PSS films in order to harvest heat via a vertical temperature gradient.
An output power density of 33 μW cm−2 is generated at a temperature difference
of 40 K, showing the potential application for low-grade wearable electronic devices.

text: Characterizing and controlling entanglement in quantum materials is crucial
for the development of next-generation quantum technologies. However, defining
a quantifiable figure of merit for entanglement in macroscopic solids is theoretically
and experimentally challenging. At equilibrium the presence of entanglement can
be diagnosed by extracting entanglement witnesses from spectroscopic observables
and a nonequilibrium extension of this method could lead to the discovery of novel
dynamical phenomena. Here, we propose a systematic approach to quantify the time-dependent
quantum Fisher information and entanglement depth of transient states of quantum
materials with time-resolved resonant inelastic x-ray scattering. Using a quarter-filled
extended Hubbard model as an example, we benchmark the efficiency of this approach
and predict a light-enhanced many-body entanglement due to the proximity to a
phase boundary. Our work sets the stage for experimentally witnessing and controlling
entanglement in light-driven quantum materials via ultrafast spectroscopic measurements.

text: Aromatic side chains are important reporters of the plasticity of proteins,
and often form important contacts in protein--protein interactions. By studying
a pair of structurally homologous cross-β amyloid fibrils, HET-s and HELLF, with
a specific isotope-labeling approach and magic-angle-spinning (MAS) NMR, we have
characterized the dynamic behavior of Phe and Tyr aromatic rings to show that
the hydrophobic amyloid core is rigid, without any sign of "breathing motions"
over hundreds of milliseconds at least. Aromatic residues exposed at the fibril
surface have a rigid ring axis but undergo ring flips, on a variety of time scales
from ns to µs. Our approach provides direct insight into hydrophobic-core motions,
enabling a better evaluation of the conformational heterogeneity generated from
a NMR structural ensemble of such amyloid cross-β architecture.

text: The multicomponent approach allows to incorporate several functionalities
into a single covalent organic framework (COF) and consequently allows the construction
of bifunctional materials for cooperative catalysis. The well-defined structure
of such multicomponent COFs is furthermore ideally suited for structure-activity
relationship studies. We report a series of multicomponent COFs that contain acridine-
and 2,2’-bipyridine linkers connected through 1,3,5-benzenetrialdehyde derivatives.
The acridine motif is responsible for broad light absorption, while the bipyridine
unit enables complexation of nickel catalysts. These features enable the usage
of the framework materials as catalysts for light-mediated carbon−heteroatom cross-couplings.
Variation of the node units shows that the catalytic activity correlates to the
keto-enamine tautomer isomerism. This allows switching between high charge-carrier
mobility and persistent, localized charge-separated species depending on the nodes,
a tool to tailor the materials for specific reactions. Moreover, nickel-loaded
COFs are recyclable and catalyze cross-couplings even using red light irradiation.

text: The influence of structural modifications on the catalytic activity of carbon
materials is poorly understood. A collection of carbonaceous materials with different
pore networks and high nitrogen content was characterized and used to catalyze
four reactions to deduce structure–activity relationships. The CO2 cycloaddition
and Knoevenagel reaction depend on Lewis basic sites (electron-rich nitrogen species).
The absence of large conjugated carbon domains resulting from the introduction
of large amounts of nitrogen in the carbon network is responsible for poor redox
activity, as observed through the catalytic reduction of nitrobenzene with hydrazine
and the catalytic oxidation of 3,3′,5,5′-tetramethylbenzidine using hydroperoxide.
The material with the highest activity towards Lewis acid catalysis (in the hydrolysis
of (dimethoxymethyl)benzene to benzaldehyde) is the most effective for small molecule
activation and presents the highest concentration of electron-poor nitrogen species.

text: Physical catalysts often have multiple sites where reactions can take place.
One prominent example is single-atom alloys, where the reactive dopant atoms can
preferentially locate in the bulk or at different sites on the surface of the
nanoparticle. However, ab initio modeling of catalysts usually only considers
one site of the catalyst, neglecting the effects of multiple sites. Here, nanoparticles
of copper doped with single-atom rhodium or palladium are modeled for the dehydrogenation
of propane. Single-atom alloy nanoparticles are simulated at 400–600 K, using
machine learning potentials trained on density functional theory calculations,
and then the occupation of different single-atom active sites is identified using
a similarity kernel. Further, the turnover frequency for all possible sites is
calculated for propane dehydrogenation to propene through microkinetic modeling
using density functional theory calculations. The total turnover frequencies of
the whole nanoparticle are then described from both the population and the individual
turnover frequency of each site. Under operating conditions, rhodium as a dopant
is found to almost exclusively occupy (111) surface sites while palladium as a
dopant occupies a greater variety of facets. Undercoordinated dopant surface sites
are found to tend to be more reactive for propane dehydrogenation compared to
the (111) surface. It is found that considering the dynamics of the single-atom
alloy nanoparticle has a profound effect on the calculated catalytic activity
of single-atom alloys by several orders of magnitude.

text: 'Integrating light-sensitive molecules within nanoparticle (NP) assemblies
is an attractive approach to fabricate new photoresponsive nanomaterials. Here,
we describe the concept of photocleavable anionic glue (PAG): small trianions
capable of mediating interactions between (and inducing the aggregation of) cationic
NPs by means of electrostatic interactions. Exposure to light converts PAGs into
dianionic products incapable of maintaining the NPs in an assembled state, resulting
in light-triggered disassembly of NP aggregates. To demonstrate the proof-of-concept,
we work with an organic PAG incorporating the UV-cleavable o-nitrobenzyl moiety
and an inorganic PAG, the photosensitive trioxalatocobaltate(III) complex, which
absorbs light across the entire visible spectrum. Both PAGs were used to prepare
either amorphous NP assemblies or regular superlattices with a long-range NP order.
These NP aggregates disassembled rapidly upon light exposure for a specific time,
which could be tuned by the incident light wavelength or the amount of PAG used.
Selective excitation of the inorganic PAG in a system combining the two PAGs results
in a photodecomposition product that deactivates the organic PAG, enabling nontrivial
disassembly profiles under a single type of external stimulus.'

text: The mammalian hippocampal formation (HF) plays a key role in several higher
brain functions, such as spatial coding, learning and memory. Its simple circuit
architecture is often viewed as a trisynaptic loop, processing input originating
from the superficial layers of the entorhinal cortex (EC) and sending it back
to its deeper layers. Here, we show that excitatory neurons in layer 6b of the
mouse EC project to all sub-regions comprising the HF and receive input from the
CA1, thalamus and claustrum. Furthermore, their output is characterized by unique
slow-decaying excitatory postsynaptic currents capable of driving plateau-like
potentials in their postsynaptic targets. Optogenetic inhibition of the EC-6b
pathway affects spatial coding in CA1 pyramidal neurons, while cell ablation impairs
not only acquisition of new spatial memories, but also degradation of previously
acquired ones. Our results provide evidence of a functional role for cortical
layer 6b neurons in the adult brain.

text: Germline determination is essential for species survival and evolution in
multicellular organisms. In most flowering plants, formation of the female germline
is initiated with specification of one megaspore mother cell (MMC) in each ovule;
however, the molecular mechanism underlying this key event remains unclear. Here
we report that spatially restricted auxin signaling promotes MMC fate in Arabidopsis.
Our results show that the microRNA160 (miR160) targeted gene ARF17 (AUXIN RESPONSE
FACTOR17) is required for promoting MMC specification by genetically interacting
with the SPL/NZZ (SPOROCYTELESS/NOZZLE) gene. Alterations of auxin signaling cause
formation of supernumerary MMCs in an ARF17- and SPL/NZZ-dependent manner. Furthermore,
miR160 and ARF17 are indispensable for attaining a normal auxin maximum at the
ovule apex via modulating the expression domain of PIN1 (PIN-FORMED1) auxin transporter.
Our findings elucidate the mechanism by which auxin signaling promotes the acquisition
of female germline cell fate in plants.

text: The inadequate understanding of the mechanisms that reversibly convert molecular
sulfur (S) into lithium sulfide (Li2S) via soluble polysulfides
(PSs) formation impedes the development of high-performance lithium-sulfur (Li-S)
batteries with non-aqueous electrolyte solutions. Here, we use operando small
and wide angle X-ray scattering and operando small angle neutron scattering (SANS)
measurements to track the nucleation, growth and dissolution of solid deposits
from atomic to sub-micron scales during real-time Li-S cell operation. In particular,
stochastic modelling based on the SANS data allows quantifying the nanoscale phase
evolution during battery cycling. We show that next to nano-crystalline Li2S
the deposit comprises solid short-chain PSs particles. The analysis of the experimental
data suggests that initially, Li2S2
precipitates from the solution and then is partially converted via solid-state
electroreduction to Li2S. We further demonstrate that mass
transport, rather than electron transport through a thin passivating film, limits
the discharge capacity and rate performance in Li-S cells.

text: The development dynamics and self-organization of glandular branched epithelia
is of utmost importance for our understanding of diverse processes ranging from
normal tissue growth to the growth of cancerous tissues. Using single primary
murine pancreatic ductal adenocarcinoma (PDAC) cells embedded in a collagen matrix
and adapted media supplementation, we generate organoids that self-organize into
highly branched structures displaying a seamless lumen connecting terminal end
buds, replicating in vivo PDAC architecture. We identify distinct morphogenesis
phases, each characterized by a unique pattern of cell invasion, matrix deformation,
protein expression, and respective molecular dependencies. We propose a minimal
theoretical model of a branching and proliferating tissue, capturing the dynamics
of the first phases. Observing the interaction of morphogenesis, mechanical environment
and gene expression in vitro sets a benchmark for the understanding of self-organization
processes governing complex organoid structure formation processes and branching
morphogenesis.

text: The question of how RNA, as the principal carrier of genetic information evolved
is fundamentally important for our understanding of the origin of life. The RNA
molecule is far too complex to have formed in one evolutionary step, suggesting
that ancestral proto-RNAs (first ancestor of RNA) may have existed, which evolved
over time into the RNA of today. Here we show that isoxazole nucleosides, which
are quickly formed from hydroxylamine, cyanoacetylene, urea and ribose, are plausible
precursors for RNA. The isoxazole nucleoside can rearrange within an RNA-strand
to give cytidine, which leads to an increase of pairing stability. If the proto-RNA
contains a canonical seed-nucleoside with defined stereochemistry, the seed-nucleoside
can control the configuration of the anomeric center that forms during the in-RNA
transformation. The results demonstrate that RNA could have emerged from evolutionarily
primitive precursor isoxazole ribosides after strand formation.

text: Photoionization is a process taking place on attosecond time scales. How its
properties evolve from isolated particles to the condensed phase is an open question
of both fundamental and practical relevance. Here, we review recent work that
has advanced the study of photoionization dynamics from atoms to molecules, clusters
and the liquid phase. The first measurements of molecular photoionization delays
have revealed the attosecond dynamics of electron emission from a molecular shape
resonance and their sensitivity to the molecular potential. Using electron-ion
coincidence spectroscopy these measurements have been extended from isolated molecules
to clusters. A continuous increase of the delays with the water-cluster size has
been observed up to a size of 4-5 molecules, followed by a saturation towards
larger clusters. Comparison with calculations has revealed a correlation of the
time delay with the spatial extension of the created electron hole. Using cylindrical
liquid-microjet techniques, these measurements have also been extended to liquid
water, revealing a delay relative to isolated water molecules that was very similar
to the largest water clusters studied. Detailed modeling based on Monte-Carlo
simulations confirmed that these delays are dominated by the contributions of
the first two solvation shells, which agrees with the results of the cluster measurements.
These combined results open the perspective of experimentally characterizing the
delocalization of electronic wave functions in complex systems and studying their
evolution on attosecond time scales.

text: Photoredox-mediated Ni-catalyzed cross-couplings are powerful transformations
to form carbon–heteroatom bonds and are generally photocatalyzed by noble metal
complexes. Low-cost and easy-to-prepare carbon dots (CDs) are attractive quasi-homogeneous
photocatalyst alternatives, but their applicability is limited by their short
photoluminescence (PL) lifetimes. By tuning the surface and PL properties of CDs,
we designed colloidal CD nano-photocatalysts for a broad range of Ni-mediated
cross-couplings between aryl halides and nucleophiles. In particular, a CD decorated
with amino groups permitted coupling to a wide range of aryl halides and thiols
under mild, base-free conditions. Mechanistic studies suggested dynamic quenching
of the CD excited state by the Ni co-catalyst and identified that pyridinium iodide
(pyHI), a previously used additive in metallaphotocatalyzed cross-couplings, can
also act as a photocatalyst in such transformations.

text: We demonstrate that several visible-light-mediated carbon−heteroatom cross-coupling
reactions can be carried out using a photoactive NiII precatalyst that forms in
situ from a nickel salt and a bipyridine ligand decorated with two carbazole groups
(Ni(Czbpy)Cl2). The activation of this precatalyst towards cross-coupling reactions
follows a hitherto undisclosed mechanism that is different from previously reported
light-responsive nickel complexes that undergo metal-to-ligand charge transfer.
Theoretical and spectroscopic investigations revealed that irradiation of Ni(Czbpy)Cl2
with visible light causes an initial intraligand charge transfer event that triggers
productive catalysis. Ligand polymerization affords a porous, recyclable organic
polymer for heterogeneous nickel catalysis of cross-coupling reactions. The heterogeneous
catalyst shows stable performance in a packed-bed flow reactor during a week of
continuous operation.

text: Confining molecules within well-defined nanosized spaces can profoundly alter
their physicochemical characteristics. For example, the controlled aggregation
of chromophores into discrete oligomers has been shown to tune their optical properties
whereas encapsulation of reactive species within molecular hosts can increase
their stability. The resazurin/resorufin pair has been widely used for detecting
redox processes in biological settings; yet, how tight confinement affects the
properties of these two dyes remains to be explored. Here, we show that a flexible
PdII6L4 coordination
cage can efficiently encapsulate both resorufin and resazurin in the form of dimers,
dramatically modulating their optical properties. Furthermore, binding within
the cage significantly decreases the reduction rate of resazurin to resorufin,
and the rate of the subsequent reduction of resorufin to dihydroresorufin. During
our studies, we also found that upon dilution, the PdII6L4
cage disassembles to afford PdII2L2
species, which lacks the ability to form inclusion complexes – a process that
can be reversed upon the addition of the strongly binding resorufin/resazurin
guests. We expect that the herein disclosed ability of a water-soluble cage to
reversibly modulate the optical and chemical properties of a molecular redox probe
will expand the versatility of synthetic fluorescent probes in biologically relevant
environments.

text: Molecular confinement effects can profoundly alter the physicochemical properties
of the confined species. A plethora of organic molecules were encapsulated within
the cavities of supramolecular hosts, and the impact of the cavity size and polarity
was widely investigated. However, the extent to which the properties of the confined
guests can be affected by the symmetry of the cage─which dictates the shape of
the cavity─remains to be understood. Here we show that cage symmetry has a dramatic
effect on the equilibrium between two isomers of the encapsulated spiropyran guests.
Working with two Pd-based coordination cages featuring similarly sized but differently
shaped hydrophobic cavities, we found a highly selective stabilization of the
isomer whose shape matches that of the cavity of the cage. A Td-symmetric cage
stabilized the spiropyrans’ colorless form and rendered them photochemically inert.
In contrast, a D2h-symmetric cage favored the colored isomer, while maintaining
reversible photoswitching between the two states of the encapsulated spiropyrans.
We also show that the switching kinetics strongly depend on the substitution pattern
on the spiropyran scaffold. This finding was used to fabricate a time-sensitive
information storage medium with tunable lifetimes of the encoded messages.

text: Confinement within molecular cages can dramatically modify the physicochemical
properties of the encapsulated guest molecules, but such host-guest complexes
have mainly been studied in a static context. Combining confinement effects with
fast guest exchange kinetics could pave the way toward stimuli-responsive supramolecular
systems—and ultimately materials—whose desired properties could be tailored “on
demand” rapidly and reversibly. Here, we demonstrate rapid guest exchange between
inclusion complexes of an open-window coordination cage that can simultaneously
accommodate two guest molecules. Working with two types of guests, anthracene
derivatives and BODIPY dyes, we show that the former can substantially modify
the optical properties of the latter upon noncovalent heterodimer formation. We
also studied the light-induced covalent dimerization of encapsulated anthracenes
and found large effects of confinement on reaction rates. By coupling the photodimerization
with the rapid guest exchange, we developed a new way to modulate fluorescence
using external irradiation.
