text: "Abstract\r\n We demonstrate
the fabrication of micron-wide tungsten silicide superconducting nanowire single-photon
detectors on a silicon substrate using laser lithography. We show saturated internal
detection efficiencies with wire widths ranging from 0.59 µm
to 1.43 µm under illumination at 1550 nm. We demonstrate
both straight wires, as well as meandered structures. Single-photon sensitivity
is shown in devices up to 4 mm in length. Laser-lithographically written devices
allow for fast and easy structuring of large areas while maintaining a saturated
internal efficiency for wire widths around 1 µm."

text: "Abstract\r\n Lithium niobate
is a promising platform for integrated quantum optics. In this platform, we aim
to efficiently manipulate and detect quantum states by combining superconducting
single photon detectors and modulators. The cryogenic operation of a superconducting
single photon detector dictates the optimisation of the electro-optic modulators
under the same operating conditions. To that end, we characterise a phase modulator,
directional coupler, and polarisation converter at both ambient and cryogenic
temperatures. The operation voltage \r\n \r\n \r\n \r\n V\r\n

\ \r\n \r\n of these
modulators increases, due to the decrease in the electro-optic effect, by 74%

converter below 8.5\r\n \r\n \r\n \r\n K\r\n \r\n \r\n

The phase modulator preserves its broadband nature and modulates light in the

text: Superconducting Nanowire Single Photon Detectors (SNSPDs) have become
an integral part of quantum optics in recent years because of their high performance
in single photon detection. We present a method to replace the electrical input
by supplying the required bias current via the photocurrent of a photodiode situated
on the cold stage of the cryostat. Light is guided to the bias photodiode through
an optical fiber, which enables a lower thermal conduction and galvanic isolation
between room temperature and the cold stage. We show that an off-the-shelf InGaAs–InP
photodiode exhibits a responsivity of at least 0.55 A/W at 0.8 K. Using this device
to bias an SNSPD, we characterize the count rate dependent on the optical power
incident on the photodiode. This configuration of the SNSPD and photodiode shows
an expected plateau in the single photon count rate with an optical bias power
on the photodiode above 6.8 µW. Furthermore, we compare the same detector under
both optical and electrical bias, and show there is no significant changes in
performance. This has the advantage of avoiding an electrical input cable, which
reduces the latent heat load by a factor of 100 and, in principle, allows for
low loss RF current supply at the cold stage.

text: Recent analyses by polarization resolved second-harmonic (SH) microscopy have
demonstrated that ferroelectric (FE) domain walls (DWs) can possess non-Ising
wall characteristics and topological nature. These analyses rely on locally analyzing
the properties, directionality, and magnitude of the second-order nonlinear tensor.
However, when inspecting FE DWs with SH microscopy, a manifold of different effects
may contribute to the observed signal difference between domains and DWs, i.e.,
far-field interference, Čerenkov-type phase-matching (CSHG), and changes in the
aforementioned local nonlinear optical properties. They all might be present at
the same time and, therefore, require careful interpretation and separation. In
this work, we demonstrate how the particularly strong Čerenkov-type contrast can
selectively be blocked using dark- and bright-field SH microscopy. Based on this
approach, we show that other contrast mechanisms emerge that were previously overlayed
by CSHG but can now be readily selected through the appropriate experimental geometry.
Using the methods presented, we show that the strength of the CSHG contrast compared
to the other mechanisms is approximately 22 times higher. This work lays the foundation
for the in-depth analysis of FE DW topologies by SH microscopy.

text: Spontaneous Raman spectroscopy (SR) is a versatile method for analysis and
visualization of ferroelectric crystal structures, including domain walls. Nevertheless,
the necessary acquisition time makes SR impractical for in situ analysis and large
scale imaging. In this work, we introduce broadband coherent anti-Stokes Raman
spectroscopy (B-CARS) as a high-speed alternative to conventional Raman techniques
and demonstrate its benefits for ferroelectric domain wall analysis. Using the
example of poled lithium niobate, we compare the spectral output of both techniques
in terms of domain wall signatures and imaging capabilities. We extract the Raman-like
resonant part of the coherent anti-Stokes signal via a Kramers–Kronig-based phase
retrieval algorithm and compare the raw and phase-retrieved signals to SR characteristics.
Finally, we propose a mechanism for the observed domain wall signal strength that
resembles a Čerenkov-like behavior, in close analogy to domain wall signatures
obtained by second-harmonic generation imaging. We, thus, lay here the foundations
for future investigations on other poled ferroelectric crystals using B-CARS.

text: Thin-film materials from μm thickness down to single-atomic-layered 2D materials
play a central role in many novel electronic and optical applications. Coherent,
nonlinear optical (NLO) μ-spectroscopy offers insight into the local thickness,
stacking order, symmetry, or electronic and vibrational properties. Thin films
and 2D materials are usually supported on multi-layered substrates leading to
(multi-)reflections, interference, or phase jumps at interfaces during μ-spectroscopy,
which all can make the interpretation of experiments particularly challenging.
The disentanglement of the influence parameters can be achieved via rigorous theoretical
analysis. In this work, we compare two self-developed modeling approaches, a semi-analytical
and a fully vectorial model, to experiments carried out in thin-film geometry
for two archetypal NLO processes, second-harmonic and third-harmonic generation.
In particular, we demonstrate that thin-film interference and phase matching do
heavily influence the signal strength. Furthermore, we work out key differences
between three and four photon processes, such as the role of the Gouy-phase shift
and the focal position. Last, we can show that a relatively simple semi-analytical
model, despite its limitations, is able to accurately describe experiments at
a significantly lower computational cost as compared to a full vectorial modeling.
This study lays the groundwork for performing quantitative NLO μ-spectroscopy
on thin films and 2D materials, as it identifies and quantifies the impact of
the corresponding sample and setup parameters on the NLO signal, in order to distinguish
them from genuine material properties.<

text: Second harmonic (SH) microscopy represents a powerful tool for the investigation
of crystalline systems, such as ferroelectrics and their domain walls (DWs). Under
the condition of normal dispersion, i.e., the refractive index at the SH wavelength
is larger as compared to the refractive index at the fundamental wavelength, n(2ω)>n(ω),
bulk crystals will generate no SH signal. Should the bulk, however, contain DWs,
an appreciable SH signal will still be detectable at the location of DWs stemming
from the Čerenkov mechanism. In this work, we demonstrate both how SH signals
are generated in bulk media and how the Čerenkov mechanism can be inhibited by
using anomalous dispersion, i.e., n(ω)Journal of Applied

text: Recently, ferroelectric domain walls (DWs) have attracted considerable attention
due to their intrinsic topological effects and their huge potential for optoelectronic
applications. In contrast, many of the underlying physical properties and phenomena
are not well characterized. In this regard, analyzing the vibrational properties,
e.g. by Raman spectroscopy, provides direct access to the various local material
properties, such as strains, defects or electric fields. While the optical phonon
spectra of DWs have been widely investigated in the past, no reports on the acoustic
phonon properties of DWs exist. In this work, we present a joint Raman and Brillouin
visualization of ferroelectric DWs in the model ferroelectric lithium niobate.
This is possible by using a combined Raman and virtually imaged phased array Brillouin
setup. Here, we show that DWs can be visualized via frequency shifts observed
in the acoustic phonons, as well. The observed contrast then is qualitatively
explained by models adapted from Raman spectroscopy. This work, hence, provides
a novel route to study ferroelectric DWs and their intrinsic mechanical properties.

text: AlSi casting alloys combine excellent castability with high strength. Hence,
this group of alloys is often used in the automotive sector. The challenge for
this application is the brittle character of these alloys which leads to cracks
during joint formation when mechanical joining technologies are used. A rise in
ductility can be achieved by a considerable increase in the solidification rate
which results in grain refinement. High solidification rates can be realized in
twin–roll casting (TRC) by water-cooled rolls. Therefore, a hypoeutectic EN AC–AlSi9
(for European Norm - aluminum cast product) is manufactured by the TRC process
and analyzed. Subsequently, joining investigations are performed on castings in
as-cast and heat-treated condition using the self-piercing riveting process considering
the joint formation and the load-bearing capacity. Due to the fine microstructure,
the crack initiation can be avoided during joining, while maintaining the joining
parameters, especially by specimens in heat treatment conditions. Furthermore,
due to the extremely fine microstructure, the load-bearing capacity of the joint
can be significantly increased in terms of the maximum load-bearing force and
the energy absorbed.

text: Quantitative speciation data for alternative fuels is highly desired to assess
their emission potential and to develop and validate chemical kinetic models.
In terms of substitute choices for fossil diesel are oxymethylene ethers (OMEs)
strongly discussed. Due to the absence of carbon-carbon bonds, soot emis-sions
from combustion of OMEs are low, but significant emissions of unregulated pollutants
such as alde-hydes emerge. The combustion behavior of OME fuels with different
chain lengths, OME0-4, was investigated in lam-inar premixed low-pressure flames
using complementary molecular-beam mass spectrometry (MBMS) techniques. MBMS sampling
provides an in-situ access directly into the reaction zone of the flame. Al-most
all chemical species involved in the oxidation process can be detected and quantified
simultane-ously. Neat OME0-3 flames were analyzed by electron ionization (EI)
MBMS with high mass resolution ( R approximate to 3900) providing exact elementary
composition. To obtain isomer-specific information, an OME1- doped hydrogen flame
and a stochiometric OME4 flame were studied by double-imaging photoelectron photoion
coincidence (i2PEPICO) spectroscopy. Both, EI-MBMS detection and i2PEPICO spectroscopy,
en-ables a complete overview of all intermediates. The results show a dominance
of oxygenated intermediates for all measured conditions. Mole fraction profiles
for the most important species are presented (i.e. formaldehyde, methanol, methyl
formate and formic acid) and compared to modeling results. Hydrocarbons with more
than four carbon atoms were not detected under the investigated conditions. Isomers
such as ethanol/dimethyl ether (m/z = 46) and ethenol/acetaldehyde (m/z = 44)
could be separated using threshold photoelectron spectra for clear iden-tification
and photoionization efficiency curves for quantification. This investigation permits
the discus-sion and analysis of systematic trends, including intermediate species,
for the combustion of the studied series of oxymethylene ether fuels. (c) 2022

text: Recent progress in molecular combustion chemistry allows for detailed investigation
of the intermediate species pool even for complex chemical fuel compositions,
as occur for technical fuels. This study pro-vides detailed investigation of a
comprehensive set of complex alternative gasoline fuels obtained from laminar
flow reactors equipped with molecular-beam sampling techniques for observation
of the com-bustion intermediate species pool in homogeneous gas phase reactions.
The combination of ionization techniques including double-imaging photoelectron
photoion coincidence (i2PEPICO) spectroscopy enables deeper mechanistic insights
into the underlying reaction network relevant to technical fuels. The se-lected
fuels focus on contemporary automotive engine application as drop-in fuels compliant
to European EN 228 specification for gasoline. Therefore, potential alternative
gasoline blends containing oxygenated hydrocarbons as octane improvers obtainable
from bio-technological production routes, e.g., ethanol, iso- butanol, methyl
tert -butyl ether (MTBE), and ethyl tert -butyl ether (ETBE), as well as a Fischer-Tropsch
surrogate were investigated. The fuel set is completed by two synthetic naphtha
fractions obtained from Fischer-Tropsch and methanol-to-gasoline processes alongside
with a fossil reference gasoline. In total, speciation data for 11 technical fuels
from two atmospheric flow reactor setups are presented. Detailed main and intermediate
species profiles are provided for slightly rich ( 4) = 1.2) and lean ( 4) = 0.8)
con-ditions for intermediate to high temperatures. Complementary, the isomer distribution
on different mass channels, like m/z = 78 u fulvene/benzene, of four gasolines
was investigated. Experimental findings are analyzed in terms of the detailed
fuel composition and literature findings for molecular combustion chemistry. Influences
of oxygenated fuel components as well as composition of the hydrocarbon frac-tions
are examined with a particular focus on the soot precursor chemistry. This dataset
is available for validation of chemical kinetic mechanisms for realistic gasolines
containing oxygenated hydrocarbons.(c) 2021 The Combustion Institute. Published

text: "AbstractThe thermal decomposition of Zr(acac)4
is studied in a SiC-microreactor on the micro-second time scale. By utilizing
synchrotron radiation and photoelectron photoion coincidence spectroscopy, six
important zirconium intermediates, as for instance Zr(C5H7O2)2(C5H6O2),
and Zr(C5H6O2)2,
are identified in the gas phase for the first time. The adiabatic ionization thresholds
of intermediately formed zirconium species are estimated and the main products
of their thermal decomposition, acetylacetone, acetylallene and acetone are characterized
unambiguously and isomer-selectively. Based on all detected intermediates, we
deduce the predominant pyrolysis pathways of the precursor in the temperature
range from 400 to 900 K. Our findings are complemented by numerical simulations
of the flow field in the microreactor, which show that the choice of dilution
gas significantly influences the temperature profile and residence times in the
microreactor, such that helium provides a more uniform flow field than argon and
should preferentially be used.\r\n Graphical
abstract\r\n Using a soft ionization
method coupled to velocity map imaging (VMI), leads to valuable insights in the
thermal decomposition of Zr(C5H7O2)4,
used in the synthesis of functional nanomaterials and ceramic coatings. Thanks
