text: Resistance spot‐welded joints containing press‐hardened steels are
seen to exhibit a fracture mode called total dome failure, where the weld nugget
completely separates from one steel sheet along the weld nugget edge. The effect
of weld nugget shape and material property gradients is studied based on damage
mechanics modeling and experimental validation to shed light on the underlying
influencing factors. For a three‐steel‐sheet spot‐welded joint combining DP600
(1.5 mm)–CR1900T (1.0 mm)–CR1900T (1.0 mm), experiments under shear loading reveal
that fracture occurs in the DP600 sheet along the weld nugget edge. In subsequent
numerical simulation studies with damage mechanics models whose parameters are
independently calibrated for every involved material configuration, three variations
of the geometrical joint configuration are considered—an approximation of the
real joint, one variation with a steeper weld nugget shape, and one variation
with a less pronounced gradient between weld nugget material and heat‐affected
zone material properties. The results of the finite‐element simulations show that
a shallower weld nugget and a more pronounced material gradient lead to a faster
increase of plastic strain at the edge of the weld nugget and promote the occurrence
of total dome failure.

text: Through tailoring the geometry and design of biomaterials, additive
manufacturing is revolutionizing the production of metallic patient-specific implants,
e.g., the Ti-6Al-7Nb alloy. Unfortunately, studies investigating this alloy showed
that additively produced samples exhibit anisotropic microstructures. This anisotropy
compromises the mechanical properties and complicates the loading state in the
implant. Moreover, the minimum requirements as specified per designated standards
such as ISO 5832-11 are not met. The remedy to this problem is performing a conventional
heat treatment. As this route requires energy, infrastructure, labor, and expertise,
which in turn mean time and money, many of the additive manufacturing benefits
are negated. Thus, the goal of this work was to achieve better isotropy by applying
only adapted additive manufacturing process parameters, specifically focusing
on the build orientations. In this work, samples orientated in 90°, 45°, and 0°
directions relative to the building platform were manufactured and tested. These
tests included mechanical (tensile and fatigue tests) as well as microstructural
analyses (SEM and EBSD). Subsequently, the results of these tests such as fractography
were correlated with the acquired mechanical properties. These showed that 90°-aligned
samples performed best under fatigue load and that all requirements specified
by the standard regarding monotonic load were met.

text: Due to the hydrolytic instability of LiPF6 in carbonate-based solvents, HF
is a typical impurity in Li-ion battery electrolytes. HF significantly influences
the performance of Li-ion batteries, for example by impacting the formation of
the solid electrolyte interphase at the anode and by affecting transition metal
dissolution at the cathode. Additionally, HF complicates studying fundamental
interfacial electrochemistry of Li-ion battery electrolytes, such as direct anion
reduction, because it is electrocatalytically relatively unstable, resulting in
LiF passivation layers. Methods to selectively remove ppm levels of HF from LiPF6-containing
carbonate-based electrolytes are limited. We introduce and benchmark a simple
yet efficient electrochemical in situ method to selectively remove ppm amounts
of HF from LiPF6-containing carbonate-based electrolytes. The basic idea is the
application of a suitable potential to a high surface-area metallic electrode
upon which only HF reacts (electrocatalytically) while all other electrolyte components
are unaffected under the respective conditions.

text: The technical importance of paraffins as phase change materials (PCM) in heat
storage systems increases. Knowledge on the thermal conductivity of paraffins
is necessary for the design and optimization of heat storage systems. However,
for most paraffins solely the thermal conductivity of the liquid state has been
sufficiently investigated. For the solid state, precise thermal conductivity data
are only known for a few paraffins, while only generalized values are available
for the remainder, some of which contradict each other. In this study, a measurement
setup based on the modified guarded hot plate method is developed. It is used
to investigate the thermal conductivity of several paraffines in the solid state,
including pure n-docosane and its compounds with different types and concentrations
of graphite. For n-docosane in the solid state, the thermal conductivity is determined
to be 0.49 W/(m K). A particle size of 200 μm with a spherical shape turns out
to be optimal to increase the thermal conductivity. This allows the thermal conductivity
of a compound with 10% graphite to increase by a factor of three compared to the
pure paraffin. Furthermore, significant differences to thermal conductivity data
from the literature are found.

text: "Abstract\r\n The accessibility
to rheological parameters for concrete is becoming more and more relevant. This
is mainly related to the constantly emerging challenges, such as not only the
development of high-strength concretes is progressing very fast but also the simulation
of the flow behaviour is of high importance. The main problem, however, is that
the rheological characterisation of fresh concrete is not possible via commercial
rheometers. The so-called concrete rheometers provide valuable relative values
for comparing different concretes, but they cannot measure absolute values. Therefore,
we developed an adaptive coaxial concrete rheometer (ACCR) that allows the measurement
of fresh concrete with particles up to \r\n \r\n
\ \r\n \r\n \r\n
\ \r\n d\r\n
\ \r\n \r\n
\ max\r\n \r\n
\ \r\n =\r\n
\ 5.5\r\n \r\n mm\r\n
\ \r\n {d}_{{\\rm{\\max
}}}=5.5\\hspace{.5em}{\\rm{mm}}\r\n \r\n
\ . The comparison of the ACCR with a commercial
rheometer showed very good agreement for selected test materials (Newtonian fluid,
shear thinning fluid, suspension, and yield stress fluid), so that self-compacting
concrete was subsequently measured. Since these measurements showed a very high
reproducibility, the rheological properties of the fresh concrete could be determined
with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified
Bingham (MB) models) were also tested for their applicability, with the Bingham
and the modified Bingham model proving to be the best suitable ones."

text: Room temperature sodium-sulfur (RT Na-S) batteries are considered potential
candidates for stationary power storage applications due to their low cost, broad
active material availability and low toxicity. Challenges, such as high volume
expansion of the S-cathode upon discharge, low electronic conductivity of S as
active material and herewith limited rate capability as well as the shuttling
of polysulfides (PSs) as intermediates often impede the cycle stability and practical
application of Na-S batteries. Sulfurized poly(acrylonitrile) (SPAN) inherently
inhibits the shuttling of PSs and shows compatibility with carbonate-based electrolytes,
however, its exact redox mechanism remained unclear to date. Herein, we implement
a commercially available and simple electrolyte into the Na-SPAN cell chemistry
and demonstrate its high rate and cycle stability. Through the application of
in situ techniques utilizing electronic impedance spectroscopy (EIS) and X-ray
absorption spectroscopy (XAS) at different depths of charge and discharge, an
insight into SPAN’s redox chemistry is obtained.

text: "Dispersion is present in every optical setup and is often an undesired effect,
especially in nonlinear-optical experiments where ultrashort laser pulses are
needed. Typically, bulky pulse compressors consisting of gratings or prisms are
used\r\nto address this issue by precompensating the dispersion of the optical
components. However, these devices are only able to compensate for a part of the
dispersion (second-order dispersion). Here, we present a compact pulse-shaping
device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral
phase delay allowing for a full dispersion control. Furthermore, with specific
phase encodings, this device can be used to temporally reshape the incident laser
pulses into more complex pulse forms such as a double pulse. We verify the performance
of our device by using an SHG-FROG measurement setup together with a retrieval
algorithm to extract the dispersion that our device applies to an incident laser
pulse."

text: (1) This work answers the question of whether and to what extent there
is a significant difference in mechanical properties when different additive manufacturing
processes are applied to the material 1.2709. The Laser-Powder-Bed-Fusion (L-PBF)
and Laser-Metal-Deposition (LMD) processes are considered, as they differ fundamentally
in the way a part is manufactured. (2) Known process parameters for low-porosity
parts were used to fabricate tensile strength specimens. Half of the specimens
were heat-treated, and all specimens were tested for mechanical properties in
a quasi-static tensile test. In addition, the material hardness was determined.
(3) It was found that, firstly, heat treatment resulted in a sharp increase in
mechanical properties such as hardness, elastic modulus, yield strength and ultimate
strength. In addition to the increase in these properties, the elongation at break
also decreases significantly after heat treatment. The choice of process, on the
other hand, does not give either process a clear advantage in terms of mechanical
properties but shows that it is necessary to consider the essential mechanical
properties for a desired application.

text: "AbstractFeCo alloys are important materials
used in pumps and motors in the offshore oil and gas drilling industry. These
alloys are subjected to marine environments with a high NaCl concentration, therefore,
corrosion and catastrophic failure are anticipated. So, the surface dissolution
of additively manufactured FeCo samples is investigated in a quasi-in
situ manner, in particular, the pitting corrosion in 5.0 wt pct
NaCl solution. The local dissolution of the same sample region is monitored after
24, 72, and 168 hours. Here, the formation of rectangular and circular pits of
ultra-fine dimensions (less than 0.5 µm) is observed
with increasing immersion time. In addition, the formation of a corrosion-inhibiting
surface layer is detected on the sample surface. Surface dissolution leads to
a change in the surface structure, however, no change in grain shape or grain
size is noticed. The surface topography after local dissolution is correlated
to the grain orientation. Quasi-in situ analysis shows
the preferential dissolution of high-angle grain boundaries (HAGBs) leading to
a change in the fraction of HAGBs and low-angle grain boundaries fraction (LAGBs).
For the FeCo sample, a potentiodynamic polarisation test reveals a corrosion potential
(Ecorr) of − 0.475 V referred to the standard hydrogen electrode
(SHE) and a corrosion exchange current density (icorr) of
0.0848 A/m2. Furthermore, quasi-in situ
experiments showed that grains oriented along certain crystallographic directions
are corroding more compared to other grains leading to a significant decrease
in the local surface height. Grains with a plane normal close to the $$\\langle
{1}00\\rangle$$\r\n
\ \r\n ⟨\r\n 100\r\n
\ ⟩\r\n \r\n
direction reveal lower surface dissolution and higher corrosion resistance, whereas
planes normal close to the $$\\langle
{11}0\\rangle$$\r\n
\ \r\n ⟨\r\n 110\r\n
\ ⟩\r\n \r\n
direction and the $$\\langle
{111}\\rangle$$\r\n
\ \r\n ⟨\r\n 111\r\n
\ ⟩\r\n \r\n
direction exhibit a higher surface dissolution."

text: Ferroelectric domain boundaries are quasi-two-dimensional functional interfaces
with high prospects for nanoelectronic applications. Despite their reduced dimensionality,
they can exhibit complex non-Ising polarization configurations and unexpected
physical properties. Here, the impact of the three-dimensional (3D) curvature
on the polarization profile of nominally uncharged 180° domain walls in LiNbO3
is studied using second-harmonic generation microscopy and 3D polarimetry analysis.
Correlations between the domain-wall curvature and the variation of its internal
polarization unfold in the form of modulations of the Néel-like character, which
we attribute to the flexoelectric effect. While the Néel-like character originates
mainly from the tilting of the domain wall, the internal polarization adjusts
its orientation due to the synergetic upshot of dipolar and monopolar bound charges
and their variation with the 3D curvature. Our results show that curved interfaces
in solid crystals may offer a rich playground for tailoring nanoscale polar states.

text: The crystal family of potassium titanyl phosphate (KTiOPO4) is a promising
material group for applications in quantum and nonlinear optics. The fabrication
of low-loss optical waveguides, as well as high-grade periodically poled ferroelectric
domain structures, requires a profound understanding of the material properties
and crystal structure. In this regard, Raman spectroscopy offers the possibility
to study and visualize domain structures, strain, defects, and the local stoichiometry,
which are all factors impacting device performance. However, the accurate interpretation
of Raman spectra and their changes with respect to extrinsic and intrinsic defects
requires a thorough assignment of the Raman modes to their respective crystal
features, which to date is only partly conducted based on phenomenological modelling.
To address this issue, we calculated the phonon spectra of potassium titanyl phosphate
and the related compounds rubidium titanyl phosphate (RbTiOPO4) and potassium
titanyl arsenate (KTiOAsO4) based on density functional theory and compared them
with experimental data. Overall, this allows us to assign various spectral features
to eigenmodes of lattice substructures with improved detail compared to previous
assignments. Nevertheless, the analysis also shows that not all features of the
spectra can unambigiously be explained yet. A possible explanation might be that
defects or long range fields not included in the modeling play a crucial rule
for the resulting Raman spectrum. In conclusion, this work provides an improved
foundation into the vibrational properties in the KTiOPO4 material family.

text: Specific heat capacity measurements by differential scanning calorimetry (DSC)
of single crystals of solid solutions of LiNbO3 and LiTaO3 are reported and compared
with corresponding ab initio calculations, with the aim to investigate the variation
of the ferroelectric Curie temperature as a function of composition. For this
purpose, single crystals of these solid solutions were grown with Czochralski
pulling along the c-axis. Elemental composition of Nb and Ta was investigated
using XRF analysis, and small samples with homogeneous and well known composition
were used for the DSC measurements. We observed that the ferroelectric Curie temperature
decreases linearly with increasing Ta concentration in the LiNb1−x Tax O3 solid
solution crystals. Furthermore, the ferroelectric transition width of a mixed
crystal appears to be smaller, as compared to pure LiTaO3.

text: The effect of plaque deposition (atherosclerosis) on blood flow behaviour
is investigated via computational fluid dynamics and structural mechanics simulations.
To mitigate the narrowing of coronary artery atherosclerosis (stenosis), the computational
modelling of auxetic and non-auxetic stents was performed in this study to minimise
or even avoid these deposition agents in the future. Computational modelling was
performed in unrestricted (open) conditions and restricted (in an artery) conditions.
Finally, stent designs were produced by additive manufacturing, and mechanical
testing of the stents was undertaken. Auxetic stent 1 and auxetic stent 2 exhibit
very little foreshortening and radial recoil in unrestricted deployment conditions
compared to non-auxetic stent 3. However, stent 2 shows structural instability
(strut failure) during unrestricted deployment conditions. For the restricted
deployment condition, stent 1 shows a higher radial recoil compared to stent 3.
In the tensile test simulations, short elongation for stent 1 due to strut failure
is demonstrated, whereas no structural instability is noticed for stent 2 and
stent 3 until 0.5 (mm/mm) strain. The as-built samples show a significant thickening
of the struts of the stents resulting in short elongations during tensile testing
compared to the simulations (stent 2 and stent 3). A modelling framework for the
stent deployment system that enables the selection of appropriate stent designs
before in vivo testing is required. This leads to the acceleration of the development
process and a reduction in time, resulting in less material wastage. The modelling
framework shall be useful for doctors designing patient-specific stents.

text: AbstractCurrently, the fused deposition modeling
(FDM) process is the most common additive manufacturing technology. The principle
of the FDM process is the strand wise deposition of molten thermoplastic polymers,
by feeding a filament trough a heated nozzle. Due to the strand and layer wise
deposition the cooling of the manufactured component is not uniform. This leads
to dimensional deviations which may cause the component to be unusable for the
desired application. In this paper, a method is described which is based on the
shrinkage compensation through the adaption of every single raster line in components
manufactured with the FDM process. The shrinkage compensation is based on a model
resulting from a DOE which considers the main influencing factors on the shrinkage
behavior of raster lines in the FDM process. An in‐house developed software analyzes
the component and locally applies the shrinkage compensation with consideration
of the boundary conditions, e.g., the position of the raster line in the component
and the process parameters. Following, a validation using a simple geometry is
conducted to show the effect of the presented adaptive scaling method.
