text: Self-propelled particles can exhibit surprising non-equilibrium behaviors,
and how they interact with obstacles or boundaries remains an important open problem.
Here we show that chemically propelled micro-rods can be captured, with little
change in their speed, into close orbits around solid spheres resting on or near
a horizontal plane. We show that this interaction between sphere and particle
is short-range, occurring even for spheres smaller than the particle length, and
for a variety of sphere materials. We consider a simple model, based on lubrication
theory, of a force- and torque-free swimmer driven by a surface slip (the phoretic
propulsion mechanism) and moving near a solid surface. The model demonstrates
capture, or movement towards the surface, and yields speeds independent of distance.
This study reveals the crucial aspects of activity–driven interactions of self-propelled
particles with passive objects, and brings into question the use of colloidal
tracers as probes of active matter.

text: Light-activated self-propelled colloids are synthesized and their active motion
is studied using optical microscopy. We propose a versatile route using different
photoactive materials, and demonstrate a multiwavelength activation and propulsion.
Thanks to the photoelectrochemical properties of two semiconductor materials (α-Fe2O3
and TiO2), a light with an energy higher than the bandgap triggers the reaction
of decomposition of hydrogen peroxide and produces a chemical cloud around the
particle. It induces a phoretic attraction with neighbouring colloids as well
as an osmotic self-propulsion of the particle on the substrate. We use these mechanisms
to form colloidal cargos as well as self-propelled particles where the light-activated
component is embedded into a dielectric sphere. The particles are self-propelled
along a direction otherwise randomized by thermal fluctuations, and exhibit a
persistent random walk. For sufficient surface density, the particles spontaneously
form ‘living crystals’ which are mobile, break apart and reform. Steering the
particle with an external magnetic field, we show that the formation of the dense
phase results from the collisions heads-on of the particles. This effect is intrinsically
non-equilibrium and a novel principle of organization for systems without detailed
balance. Engineering families of particles self-propelled by different wavelength
demonstrate a good understanding of both the physics and the chemistry behind
the system and points to a general route for designing new families of self-propelled
particles.

text: The morphological stability of biological tubes is crucial for the efficient
circulation of fluids and gases. Failure of this stability causes irregularly
shaped tubes found in multiple pathological conditions. Here, we report that Drosophila
mutants of the ESCRT III component Shrub/Vps32 exhibit a strikingly elongated
sinusoidal tube phenotype. This is caused by excessive apical membrane synthesis
accompanied by the ectopic accumulation and overactivation of Crumbs in swollen
endosomes. Furthermore, we demonstrate that the apical extracellular matrix (aECM)
of the tracheal tube is a viscoelastic material coupled with the apical membrane.
We present a simple mechanical model in which aECM elasticity, apical membrane
growth, and their interaction are three vital parameters determining the stability
of biological tubes. Our findings demonstrate a mechanical role for the extracellular
matrix and suggest that the interaction of the apical membrane and an elastic
aECM determines the final morphology of biological tubes independent of cell shape.

text: 'The regulation of cell growth in animal tissues is a question of critical
importance: most tissues contain different types of cells in interconversion and
the fraction of each type has to be controlled in a precise way, by mechanisms
that remain unclear. Here, we provide a theoretical framework for the homeostasis
of stem-cell-containing epithelial tissues using mechanical equations, which describe
the size of the tissue and kinetic equations, which describe the interconversions
of the cell populations. We show that several features, such as the evolution
of stem cell fractions during intestinal development, the shape of a developing
intestinal wall, as well as the increase in the proliferative compartment in cancer
initiation, can be studied and understood from generic modelling which does not
rely on a particular regulatory mechanism. Finally, inspired by recent experiments,
we propose a model where cell division rates are regulated by the mechanical stresses
in the epithelial sheet. We show that pressure-controlled growth can, in addition
to the previous features, also explain with few parameters the formation of stem
cell compartments as well as the morphologies observed when a colonic crypt becomes
cancerous. We also discuss optimal strategies of wound healing, in connection
with experiments on the cornea.'

text: Morphogenesis during embryo development requires the coordination of mechanical
forces to generate the macroscopic shapes of organs. We propose a minimal theoretical
model, based on cell adhesion and actomyosin contractility, which describes the
various shapes of epithelial cells and the bending and buckling of epithelial
sheets, as well as the relative stability of cellular tubes and spheres. We show
that, to understand these processes, a full 3D description of the cells is needed,
but that simple scaling laws can still be derived. The morphologies observed in
vivo can be understood as stable points of mechanical equations and the transitions
between them are either continuous or discontinuous. We then focus on epithelial
sheet bending, a ubiquitous morphogenetic process. We calculate the curvature
of an epithelium as a function of actin belt tension as well as of cell-cell and
and cell-substrate tension. The model allows for a comparison of the relative
stabilities of spherical or cylindrical cellular structures (acini or tubes).
Finally, we propose a unique type of buckling instability of epithelia, driven
by a flattening of individual cell shapes, and discuss experimental tests to verify
our predictions.

text: Spin and orbital quantum numbers play a key role in the physics of Mott insulators,
but in most systems they are connected only indirectly—via the Pauli exclusion
principle and the Coulomb interaction. Iridium-based oxides (iridates) introduce
strong spin–orbit coupling directly, such that these numbers become entwined together
and the Mott physics attains a strong orbital character. In the layered honeycomb
iridates this is thought to generate highly spin–anisotropic magnetic interactions,
coupling the spin to a given spatial direction of exchange and leading to strongly
frustrated magnetism. Here we report a new iridate structure that has the same
local connectivity as the layered honeycomb and exhibits striking evidence for
highly spin–anisotropic exchange. The basic structural units of this material
suggest that a new family of three-dimensional structures could exist, the ‘harmonic
honeycomb’ iridates, of which the present compound is the first example.

text: We investigate the structural and magnetic properties of two molecule-based
magnets synthesized from the same starting components. Their different structural
motifs promote contrasting exchange pathways and consequently lead to markedly
different magnetic ground states. Through examination of their structural and
magnetic properties we show that [Cu(pyz)(H2O)(gly)2](ClO4)2 may be considered
a quasi-one-dimensional quantum Heisenberg antiferromagnet whereas the related
compound [Cu(pyz)(gly)](ClO4), which is formed from dimers of antiferromagnetically
interacting Cu2+ spins, remains disordered down to at least 0.03 K in zero field
but shows a field-temperature phase diagram reminiscent of that seen in materials
showing a Bose-Einstein condensation of magnons.

text: Photoinduced electron transfer (PET), which causes pH-dependent quenching
of fluorescent dyes, is more effectively introduced by phenolic groups than by
amino groups which have been much more commonly used so far. That is demonstrated
by fluorescence measurements involving several classes of fluorophores. Electrochemical
measurements show that PET in several amino-modified dyes is thermodynamically
favorable, even though it was not experimentally found, underlining the importance
of kinetic aspects to the process. Consequently, the attachment of phenolic groups
allows for fast and simple preparation of a wide selection of fluorescent pH-probes
with tailor-made spectral properties, sensitive ranges, and individual advantages,
so that a large number of applications can be realized. Fluorophores carrying
phenolic groups may also be used for sensing analytes other than pH or molecular
switching and signaling.

text: Several problems arise at the O2 (positive) electrode in the Li-air battery,
including solvent/electrode decomposition and electrode passivation by insulating
Li2O2. Progress partially depends on exploring the basic electrochemistry of O2
reduction. Here we describe the effect of complexing-cations on the electrochemical
reduction of O2 in DMSO in the presence and absence of a Li salt. The solubility
of alkaline peroxides in DMSO is enhanced by the complexing-cations, consistent
with their strong interaction with reduced O2. The complexing-cations also increase
the rate of the 1-electron O2 reduction to O2•– by up to six-fold (k° = 2.4 ×10–3
to 1.5 × 10–2 cm s–1) whether or not Li+ ions are present. In the absence of Li+,
the complexing-cations also promote the reduction of O2•– to O22–. In the presence
of Li+ and complexing-cations, and despite the interaction of the reduced O2 with
the latter, SERS confirms that the product is still Li2O2.

text: Understanding charge carrier transport in Li2O2, the storage material in the
non-aqueous Li-O2 battery, is key to the development of this high-energy battery.
Here, we studied ionic transport properties and Li self-diffusion in nanocrystalline
Li2O2 by conductivity and temperature variable 7Li NMR spectroscopy. Nanostructured
Li2O2, characterized by a mean crystallite size of less than 50 nm as estimated
from X-ray diffraction peak broadening, was prepared by high-energy ball milling
of microcrystalline lithium peroxide with μm sized crystallites. At room temperature
the overall conductivity σ of the microcrystalline reference sample turned out
to be very low (3.4 × 10−13 S cm−1) which is in agreement with results from temperature-variable
7Li NMR line shape measurements. Ball-milling, however, leads to an increase of
σ by approximately two orders of magnitude (1.1 × 10−10 S cm−1); correspondingly,
the activation energy decreases from 0.89 eV to 0.82 eV. The electronic contribution
σeon, however, is in the order of 9 × 10−12 S cm−1 which makes less than 10% of
the total value. Interestingly, 7Li NMR lines of nano-Li2O2 undergo pronounced
heterogeneous motional narrowing which manifests in a two-component line shape
emerging with increasing temperatures. Most likely, the enhancement in σ can be
traced back to the generation of a spin reservoir with highly mobile Li ions;
these are expected to reside in the nearest neighbourhood of defects generated
or near the structurally disordered and defect-rich interfacial regions formed
during mechanical treatment.

text: The electrolyte in the non-aqueous (aprotic) lithium air battery has a profound
influence on the reactions that occur at the anode and cathode, and hence its
overall operation on discharge/charge. It must possess a wide range of attributes,
exceeding the requirements of electrolytes for Lithium ion batteries by far. The
most important additional issues are stability at both anode and cathode in the
presence of O2. The known problems with cycling the Li metal/non-aqueous electrolyte
interface are further complicated by O2. New and much less understood are the
reactions at the O2 cathode/electrolyte interface where the highly reversible
formation/decomposition of Li2O2 on discharge/charge is critical for the operation
of the non-aqueous lithium air battery. Many aprotic electrolytes exhibit decomposition
at the cathode during discharge and charge due to the presence of reactive reduced
O2 species affecting potential, capacity and kinetics on discharge and charge,
cyclability and calendar life. Identifying suitable electrolytes is one of the
key challenges for the non-aqueous lithium air battery at the present time. Following
the realisation that cyclability of such cells in the initially used organic carbonate
electrolytes is due to back-to-back irreversible reactions the stability of the
non-aqueous electrolytes became a major focus of research on rechargeable lithium
air batteries. This realisation led to the establishment of a suite of experimental
and computational methods capable of screening the stability of electrolytes.
These allow for greater mechanistic understanding of the reactivity and guide
the way towards designing more stable systems. A range of electrolytes based on
ethers, amides, sulfones, ionic liquids and dimethyl sulfoxide have been investigated.
All are more stable than the organic carbonates, but not all are equally stable.
Even though it was soon realised, by a number of groups, that ethers exhibit side
reactions on discharge and charge, they still remain the choice in many studies.
To date dimethyl sulfoxide and dimethylacetamide were identified as the most stable
electrolytes. In conjunction with the investigation of electrolyte stability the
importance of electrode stability became more prominent. The stability of the
electrolyte cannot be considered in isolation. Its stability depends on the synergy
between electrolyte and electrode. Carbon based electrodes promote electrolyte
decomposition and decompose on their own. Although great progress has been made
in only a few years, future work on aprotic electrolytes for Li-O2 batteries will
need to explore other electrolytes in the quest for yet lower cost, higher safety,
stability and low volatility.

text: Lithium-air batteries have received extraordinary attention recently owing
to their theoretical gravimetric energies being considerably higher than those
of Li-ion batteries. There are, however, significant challenges to practical implementation,
including low energy efficiency, cycle life, and power capability. These are due
primarily to the lack of fundamental understanding of oxygen reduction and evolution
reaction kinetics and parasitic reactions between oxygen redox intermediate species
and nominally inactive battery components such as carbon in the oxygen electrode
and electrolytes. In this article, we discuss recent advances in the mechanistic
understanding of oxygen redox reactions in nonaqueous electrolytes and the search
for electrolytes and electrode materials that are chemically stable in the oxygen
electrode. In addition, methods to protect lithium metal against corrosion by
water and dendrite formation in aqueous lithium-air batteries are discussed. Further
materials innovations lie at the heart of research and development efforts that
are needed to enable the development of lithium-oxygen batteries with enhanced
round-trip efficiency and cycle life.

text: When lithium–oxygen batteries discharge, O2 is reduced at the cathode to form
solid Li2O2. Understanding the fundamental mechanism of O2 reduction in aprotic
solvents is therefore essential to realizing their technological potential. Two
different models have been proposed for Li2O2 formation, involving either solution
or electrode surface routes. Here, we describe a single unified mechanism, which,
unlike previous models, can explain O2 reduction across the whole range of solvents
and for which the two previous models are limiting cases. We observe that the
solvent influences O2 reduction through its effect on the solubility of LiO2,
or, more precisely, the free energy of the reaction LiO2* ⇌ Li(sol)+ + O2−(sol) + ion
pairs + higher aggregates (clusters). The unified mechanism shows that low-donor-number
solvents are likely to lead to premature cell death, and that the future direction
of research for lithium–oxygen batteries should focus on the search for new, stable,
high-donor-number electrolytes, because they can support higher capacities and
can better sustain discharge.

text: Bistable switches are fundamental regulatory elements of complex systems,
ranging from electronics to living cells. Designed genetic toggle switches have
been constructed from pairs of natural transcriptional repressors wired to inhibit
one another. The complexity of the engineered regulatory circuits can be increased
using orthogonal transcriptional regulators based on designed DNA-binding domains.
However, a mutual repressor-based toggle switch comprising DNA-binding domains
of transcription-activator-like effectors (TALEs) did not support bistability
in mammalian cells. Here, the challenge of engineering a bistable switch based
on monomeric DNA-binding domains is solved via the introduction of a positive
feedback loop composed of activators based on the same TALE domains as their opposing
repressors and competition for the same DNA operator site. This design introduces
nonlinearity and results in epigenetic bistability. This principle could be used
to employ other monomeric DNA-binding domains such as CRISPR for applications
ranging from reprogramming cells to building digital biological memory.

text: 'The reaction between NiO and (0001)- and ([1\bar102])-oriented Al2O3 single
crystals has been investigated on model experimental systems by using the ReflEXAFS
technique. Depth-sensitive information is obtained by collecting data above and
below the critical angle for total reflection. A systematic protocol for data
analysis, based on the recently developed CARD code, was implemented, and a detailed
description of the reactive systems was obtained. In particular, for ([1\bar102])-oriented
Al2O3, the reaction with NiO is almost complete after heating for 6 h at 1273 K,
and an almost uniform layer of spinel is found below a mixed (NiO + spinel) layer
at the very upmost part of the sample. In the case of the (0001)-oriented Al2O3,
for the same temperature and heating time, the reaction shows a lower advancement
degree and a residual fraction of at least 30% NiO is detected in the ReflEXAFS
spectra. '

text: 'Task allocation is a classic distributed problem in which a set of p potentially
faulty processes must cooperate to perform a set of tasks. This paper considers
a new dynamic version of the problem, in which tasks are injected adversarially
during an asynchronous execution. We give the first asynchronous shared-memory
algorithm for dynamic task allocation, and we prove that our solution is optimal
within logarithmic factors. The main algorithmic idea is a randomized concurrent
data structure called a dynamic to-do tree, which allows processes to pick new
tasks to perform at random from the set of available tasks, and to insert tasks
at random empty locations in the data structure. Our analysis shows that these
properties avoid duplicating work unnecessarily. On the other hand, since the
adversary controls the input as well the scheduling, it can induce executions
where lots of processes contend for a few available tasks, which is inefficient.
However, we prove that every algorithm has the same problem: given an arbitrary
input, if OPT is the worst-case complexity of the optimal algorithm on that input,
then the expected work complexity of our algorithm on the same input is O(OPT
log3 m), where m is an upper bound on the number of tasks that are present in
the system at any given time.'

text: 'This article presents the first tight bounds on the time complexity of shared-memory
renaming, a fundamental problem in distributed computing in which a set of processes
need to pick distinct identifiers from a small namespace. We first prove an individual
lower bound of ω(k) process steps for deterministic renaming into any namespace
of size subexponential in k, where k is the number of participants. The bound
is tight: it draws an exponential separation between deterministic and randomized
solutions, and implies new tight bounds for deterministic concurrent fetch-and-increment
counters, queues, and stacks. The proof is based on a new reduction from renaming
to another fundamental problem in distributed computing: mutual exclusion. We
complement this individual bound with a global lower bound of ω(klog(k/c)) on
the total step complexity of renaming into a namespace of size ck, for any c =
1. This result applies to randomized algorithms against a strong adversary, and
helps derive new global lower bounds for randomized approximate counter implementations,
that are tight within logarithmic factors. On the algorithmic side, we give a
protocol that transforms any sorting network into a randomized strong adaptive
renaming algorithm, with expected cost equal to the depth of the sorting network.
This gives a tight adaptive renaming algorithm with expected step complexity O(log
k), where k is the contention in the current execution. This algorithm is the
first to achieve sublinear time, and it is time-optimal as per our randomized
lower bound. Finally, we use this renaming protocol to build monotone-consistent
counters with logarithmic step complexity and linearizable fetch-and-increment
registers with polylogarithmic cost.'
