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: Soluble chaperones residing in the endoplasmic reticulum (ER) play vitally
important roles in folding and quality control of newly synthesized proteins that
transiently pass through the ER en route to their final destinations. These soluble
residents of the ER are themselves endowed with an ER retrieval signal that enables
the cell to bring the escaped residents back from the Golgi. Here, by using purified
proteins, we showed that Nicotiana tabacum phytaspase, a plant aspartate-specific
protease, introduces two breaks at the C-terminus of the N. tabacum ER resident
calreticulin-3. These cleavages resulted in removal of either a dipeptide or a
hexapeptide from the C-terminus of calreticulin-3 encompassing part or all of
the ER retrieval signal. Consistently, expression of the calreticulin-3 derivative
mimicking the phytaspase cleavage product in Nicotiana benthamiana cells demonstrated
loss of the ER accumulation of the protein. Notably, upon its escape from the
ER, calreticulin-3 was further processed by an unknown protease(s) to generate
the free N-terminal (N) domain of calreticulin-3, which was ultimately secreted
into the apoplast. Our study thus identified a specific proteolytic enzyme capable
of precise detachment of the ER retrieval signal from a plant ER resident protein,
with implications for the further fate of the escaped resident.

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: 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: We report the visible light photocatalytic cleavage of trityl thioethers or
ethers under pH-neutral conditions. The method results in the formation of the
respective symmetrical disulfides and alcohols in moderate to excellent yield.
The protocol only requires the addition of a suitable photocatalyst and light
rendering it orthogonal to several functionalities, including acid labile protective
groups. The same conditions can be used to directly convert trityl-protected thiols
into unsymmetrical disulfides or selenosulfides, and to cleave trityl resins in
solid phase organic synthesis.

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: Visible-light photocatalysis provides numerous useful methodologies for synthetic
organic chemistry. However, the mechanisms of these reactions are often not fully
understood. Common mechanistic experiments mainly aim to characterize excited
state properties of photocatalysts and their interaction with other species. Recently,
in situ reaction monitoring using dedicated techniques was shown to be well-suited
for the identification of intermediates and to obtain kinetic insights, thereby
providing more holistic pictures of the reactions of interest. This minireview
surveys these technologies and discusses selected examples where reaction monitoring
was used to elucidate the mechanism of photocatalytic reactions.

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: 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: 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: We show that the optical properties of indigo carmine can be modulated by
encapsulation within a coordination cage. Depending on the host/guest molar ratio,
the cage can predominantly encapsulate either one or two dye molecules. The 1 : 1
complex is fluorescent, unique for an indigo dye in an aqueous solution. We have
also found that binding two dye molecules stabilizes a previously unknown conformation
of the cage.

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: 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: DNA nanotechnology offers a versatile toolbox for precise spatial and temporal
manipulation of matter on the nanoscale. However, rendering DNA-based systems
responsive to light has remained challenging. Herein, we describe the remote manipulation
of native (non-photoresponsive) chiral plasmonic molecules (CPMs) using light.
Our strategy is based on the use of a photoresponsive medium comprising a merocyanine-based
photoacid. Upon exposure to visible light, the medium decreases its pH, inducing
the formation of DNA triplex links, leading to a spatial reconfiguration of the
CPMs. The process can be reversed simply by turning the light off and it can be
repeated for multiple cycles. The degree of the overall chirality change in an
ensemble of CPMs depends on the CPM fraction undergoing reconfiguration, which,
remarkably, depends on and can be tuned by the intensity of incident light. Such
a dynamic, remotely controlled system could aid in further advancing DNA-based
devices and nanomaterials.

text: Redox mediators could catalyse otherwise slow and energy-inefficient cycling
of Li-S and Li-O 2 batteries by shuttling electrons/holes between the electrode
and the solid insulating storage materials. For mediators to work efficiently
they need to oxidize the solid with fast kinetics yet the lowest possible overpotential.
Here, we found that when the redox potentials of mediators are tuned via, e.g.,
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 mediators 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 requires therefore carefully considering
the surface conditions of the storage materials and electrolyte-dependent redox
potentials, which may be tuned by salt concentrations or solvents.

text: Aggregation of organic molecules can drastically affect their physicochemical
properties. For instance, the optical properties of BODIPY dyes are inherently
related to the degree of aggregation and the mutual orientation of BODIPY units
within these aggregates. Whereas the noncovalent aggregation of various BODIPY
dyes has been studied in diverse media, the ill-defined nature of these aggregates
has made it difficult to elucidate the structure–property relationships. Here,
we studied the encapsulation of three structurally simple BODIPY derivatives within
the hydrophobic cavity of a water-soluble, flexible PdII6L4 coordination cage.
The cavity size allowed for the selective encapsulation of two dye molecules,
irrespective of the substitution pattern on the BODIPY core. Working with a model,
a pentamethyl-substituted derivative, we found that the mutual orientation of
two BODIPY units in the cage’s cavity was remarkably similar to that in the crystalline
state of the free dye, allowing us to isolate and characterize the smallest possible
noncovalent H-type BODIPY aggregate, namely, an H-dimer. Interestingly, a CF3-substituted
BODIPY, known for forming J-type aggregates, was also encapsulated as an H-dimer.
Taking advantage of the dynamic nature of encapsulation, we developed a system
in which reversible switching between H- and J-aggregates can be induced for multiple
cycles simply by addition and subsequent destruction of the cage. We expect that
the ability to rapidly and reversibly manipulate the optical properties of supramolecular
inclusion complexes in aqueous media will open up avenues for developing detection
systems that operate within biological environments.

text: Photochromic molecules undergo reversible isomerization upon irradiation with
light at different wavelengths, a process that can alter their physical and chemical
properties. For instance, dihydropyrene (DHP) is a deep-colored compound that
isomerizes to light-brown cyclophanediene (CPD) upon irradiation with visible
light. CPD can then isomerize back to DHP upon irradiation with UV light or thermally
in the dark. Conversion between DHP and CPD is thought to proceed via a biradical
intermediate; bimolecular events involving this unstable intermediate thus result
in rapid decomposition and poor cycling performance. Here, we show that the reversible
isomerization of DHP can be stabilized upon confinement within a PdII6L4 coordination
cage. By protecting this reactive intermediate using the cage, each isomerization
reaction proceeds to higher yield, which significantly decreases the fatigue experienced
by the system upon repeated photocycling. Although molecular confinement is known
to help stabilize reactive species, this effect is not typically employed to protect
reactive intermediates and thus improve reaction yields. We envisage that performing
reactions under confinement will not only improve the cyclic performance of photochromic
molecules, but may also increase the amount of product obtainable from traditionally
low-yielding organic reactions.
