text: Frequency-stable lasers form the back bone of precision measurements in science
and technology. Such lasers typically attain their stability through frequency
locking to reference cavities. State-of-the-art locking performances to date had
been achieved using frequency modulation based methods, complemented with active
drift cancellation systems. We demonstrate an all passive, modulation-free laser-cavity
locking technique (squash locking) that utilizes changes in spatial beam ellipticity
for error signal generation, and a coherent polarization post-selection for noise
resilience. By comparing two identically built proof-of-principle systems, we
show a frequency locking instability of 5×10−7 relative to
the cavity linewidth at 10 s averaging. The results surpass the demonstrated performances
of methods engineered over the last five decades, potentially enabling an advancement
in the precision control of lasers, while creating avenues for bridging the performance
gaps between industrial grade lasers with scientific ones due to the afforded
simplicity and scalability.

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 prediction and realization of topological insulators have sparked great
interest in experimental approaches to the classification of materials1,2,3. The
phase transition between non-trivial and trivial topological states is important,
not only for basic materials science but also for next-generation technology,
such as dissipation-free electronics4. It is therefore crucial to develop advanced
probes that are suitable for a wide range of samples and environments. Here we
demonstrate that circularly polarized laser-field-driven high-harmonic generation
is distinctly sensitive to the non-trivial and trivial topological phases in the
prototypical three-dimensional topological insulator bismuth selenide5. The phase
transition is chemically initiated by reducing the spin–orbit interaction strength
through the substitution of bismuth with indium atoms6,7. We find strikingly different
high-harmonic responses of trivial and non-trivial topological surface states
that manifest themselves as a conversion efficiency and elliptical dichroism that
depend both on the driving laser ellipticity and the crystal orientation. The
origins of the anomalous high-harmonic response are corroborated by calculations
using the semiconductor optical Bloch equations with pairs of surface and bulk
bands. As a purely optical approach, this method offers sensitivity to the electronic
structure of the material, including its nonlinear response, and is compatible
with a wide range of samples and sample environments.

text: 'Motivated by properties-controlling potential of the strain, we investigate
strain dependence of structure, electronic, and magnetic properties of Sr2IrO4
using complementary theoretical tools: ab-initio calculations, analytical approaches
(rigid octahedra picture, Slater-Koster integrals), and extended t−J model. We
find that strain affects both Ir-Ir distance and Ir-O-Ir angle, and the rigid
octahedra picture is not relevant. Second, we find fundamentally different behavior
for compressive and tensile strain. One remarkable feature is the formation of
two subsets of bond- and orbital-dependent carriers, a compass-like model, under
compression. This originates from the strain-induced renormalization of the Ir-O-Ir
superexchange and O on-site energy. We also show that under compressive (tensile)
strain, Fermi surface becomes highly dispersive (relatively flat). Already at
a tensile strain of 1.5%, we observe spectral weight redistribution, with the
low-energy band acquiring almost purely singlet character. These results can be
directly compared with future experiments.'

text: 'Lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) based water-in-salt electrolytes
(WiSEs) has recently emerged as a new promising class of electrolytes, primarily
owing to their wide electrochemical stability windows (~3–4 V), that by far exceed
the thermodynamic stability window of water (1.23 V). Upon increasing the salt
concentration towards superconcentration the onset of the oxygen evolution reaction
(OER) shifts more significantly than the hydrogen evolution reaction (HER) does.
The OER shift has been explained by the accumulation of hydrophobic anions blocking
water access to the electrode surface, hence by double layer theory. Here we demonstrate
that the processes during oxidation are much more complex, involving OER, carbon
and salt decomposition by OER intermediates, and salt precipitation upon local
oversaturation. The positive shift in the onset potential of oxidation currents
was elucidated by combining several advanced analysis techniques: rotating ring-disk
electrode voltammetry, online electrochemical mass spectrometry, and X-ray photoelectron
spectroscopy, using both dilute and superconcentrated electrolytes. The results
demonstrate the importance of reactive OER intermediates and surface films for
electrolyte and electrode stability and motivate further studies of the nature
of the electrode.'

text: In the quest for alternate and efficient electrode materials, ternary metal
electrocatalysts (TMEs), part of the perovskite family, were synthesized and tested
for methanol electro-oxidation in alkaline media. La0.5Ca0.5MO3 (M = Ni, Co, or
Mn) was synthesized via sol-gel method. X-ray diffraction analysis revealed that
the perovskite crystal structure possesses characteristic sharp and crystalline
peaks for all synthesized ternary electrocatalysts. The average particle size
calculated using Debye–Scherrer equation was in the order of La0.5Ca0.5NiO3 (LCNO)
> La0.5Ca0.5CoO3 (LCCO)> La0.5Ca0.5MnO3 (LCMO). The elemental composition of as
prepared sample, LCCO was investigated via x-ray fluorescence spectroscopy. The
qualitative and quantitative analysis revealed the presence of La, Ca and Co in
parent crystal structure with percentage compositions of 9.0, 3.12 and 87.82%
respectively. The particle size distribution was homogenous, as determined by
scanning electron and transmission electron microscopes. The electrocatalytic
activity of the synthesized ternary electrocatalysts was studied electrochemically
by cyclic voltammetry. The calculated diffusion coefficient values showed that
electrode surface of LCNO and LCCO have limited efficiency for diffusion related
phenomenon. The heterogeneous rate constants inferred better electrode kinetics
of LCCO and LCNO which exhibited good electrocatalytic behavior; sharp anodic
peaks were observed in the potential range of +0.3 to 0.6 V and +0.6 to 0.8 V,
respectively. Methanol electro-oxidation was found minimal in case of LCMO sample.
We have observed that Co substitution at B-site of perovskite electrode materials
attains better electrochemical properties, thus in relation with reported literature.

text: Solid-state NMR spectroscopy allows the characterization of the structure,
interactions and dynamics of insoluble and/or very large proteins. Sensitivity
and resolution are often major challenges for obtaining atomic-resolution information,
in particular for very large protein complexes. Here we show that the use of deuterated,
specifically CH3-labelled proteins result in significant sensitivity gains compared
to previously employed CHD2 labelling, while line widths increase only marginally.
We apply this labelling strategy to a 468 kDa-large dodecameric aminopeptidase,
TET2, and the 1.6 MDa-large 50S ribosome subunit of Thermus thermophilus.

text: Come on in, the water's fine! Non-photoresponsive nanoparticles can be reversibly
assembled using light by placing them in an aqueous solution of a photoacid.
Upon exposure to visible light, the photoacid reduces the pH of the solution,
which induces attractive interactions between the nanoparticles. In the dark,
the resulting nanoparticle aggregates spontaneously disassemble. The process can
be repeated many times.

text: Monochromatization of high-harmonic sources has opened fascinating perspectives
regarding time-resolved photoemission from all phases of matter. Such studies
have invariably involved the use of spectral filters or spectrally dispersive
optical components that are inherently lossy and technically complex. Here we
present a new technique for the spectral selection of near-threshold harmonics
and their spatial separation from the driving beams without any optical elements.
We discover the existence of a narrow phase-matching gate resulting from the combination
of the non-collinear generation geometry in an extended medium, atomic resonances
and absorption. Our technique offers a filter contrast of up to 104 for the selected
harmonics against the adjacent ones and offers multiple temporally synchronized
beamlets in a single unified scheme. We demonstrate the selective generation of
133, 80 or 56 nm femtosecond pulses from a 400-nm driver, which is specific to
the target gas. These results open new pathways towards phase-sensitive multi-pulse
spectroscopy in the vacuum- and extreme-ultraviolet, and frequency-selective output
coupling from enhancement cavities.

text: Metallic nanoparticles co-functionalised with monolayers of UV- and CO2-sensitive
ligands were prepared and shown to respond to these two types of stimuli reversibly
and in an orthogonal fashion. The composition of the coating could be tailored
to yield nanoparticles capable of aggregating exclusively when both UV and CO2
were applied at the same time, analogously to the behaviour of an AND logic gate.

text: Supraspheres (SS) composed of hundreds to thousands of metal nanoparticles
(NPs) and crosslinked by dithiol linkers are assembled into larger structures,
which are subsequently converted into nanoporous metals (NMs). Conversion is achieved
by heating which removes organic molecules stabilizing the NPs and allows for
NP fusion. Heating of SS solutions leads to NMs of overall macroscopic dimensions;
localized radiation using collimated electron beam is used to prepare metallized
surface micropatterns. Depending on the composition of supraspherical precursors,
nanoporous materials composed of up to three metals can be obtained. Strategies
for controlling pore size and nanoscale surface roughness of these materials are
discussed.
