text: AbstractComposite materials, such as fiber
reinforced polymers, become increasingly important due to their excellent mechanical
and lightweight properties. In this respect, this paper reports the characterization
of a unidirectional carbon fiber reinforced polymer composite material. Particularly,
the mechanical behavior of the overall composite and of the individual constituents
of the composite is investigated. To this end, tensile and shear tests are performed
for the composite. As a result, statistics for five transversely isotropic material
parameters can be established for the composite. For the description of the mechanical
properties of the constituents, tensile tests for the carbon fiber as well as
for the polymer matrix are carried out. In addition, the volume fraction of fibers
in the matrix is determined experimentally using an ashing technique and Archimedes’
principle. For the Young’s modulus of the fiber, the Young’s modulus and transverse
contraction of the matrix, as well as the volume fraction of the constituents,
statistics can be concluded. The resulting mechanical properties on both scales
are useful for the application and validation of different material models and
homogenization methods. Finally, in order to validate the obtained properties
in the future, inhomogeneous tests were performed, once a flat plate with a hole
and a flat plate with semicircular notches.

text: The achievement of a flat metasurface has realized extraordinary control over
light–matter interaction at the nanoscale, enabling widespread use in imaging,
holography, and biophotonics. However, three-dimensional metasurfaces with the
potential to provide additional light–matter manipulation flexibility attract
only little interest. Here, we demonstrate a three-dimensional metasurface scheme
capable of providing dual phase control through out-of-plane plasmonic resonance
of L-shape antennas. Under circularly polarized excitation at a specific wavelength,
the L-shape antennas with rotating orientation angle act as spatially variant
three-dimensional tilted dipoles and are able to generate desire phase delay for
different polarization components. Generalized Snell's law is achieved for both
in-plane and out-of-plane dipole components through arranging such L-shape antennas
into arrays. These three-dimensional metasurfaces suggest a route for wavefront
modulation and a variety of nanophotonic applications.

text: Lightweight design is a common approach to reduce energy demand in
the use stage of vehicles. The production of lightweight materials is usually
associated with an increase in energy demand, so the environmental impacts of
lightweight structures need to be assessed holistically using a life cycle assessment.
To estimate the life cycle environmental impacts of a product in its developmental
stage, for example, by life cycle engineering, future changes in relevant influencing
factors must be considered. Prospective life cycle assessment provides methods
for integrating future scenarios into life cycle assessment studies. However,
approaches for integrating prospective life cycle assessment into product development
are limited. The objective of this work is to provide the methodological foundation
for integrating future scenarios of relevant influencing factors in the development
of lightweight structures. The applicability of the novel methodology is demonstrated
by a case study of a structural component in a steel, aluminium, and hybrid design.
The results show that appropriate decarbonisation measures can reduce the life
cycle greenhouse gas emissions by up to 95 percent until 2050. We also found that
shifts in the environmentally optimal design are possible in future scenarios.
Therefore, the methodology and data provided contribute to improved decision-making
in product development.

text: Laser structuring to improve the adhesion properties of steel substrates in
fiber-metal laminates offers many advantages that are highly suitable for modern
industrial requirements. Maintenance and energy costs are relatively low, it is
easy to automate, and there are no by-products such as chemicals or abrasives
to dispose of or recycle. This makes laser structuring a particularly environmentally
friendly process, which is nowadays more important than ever. On the other hand,
the process time for laser structuring is much higher than for chemical pre-treatment,
for example. In past studies, the time and cost efficiency of the laser structuring
process has tended to play a minor role. However, there are approaches in which
laser structured surfaces are adapted to the shear stress peaks occurring within
the adhesive layer, thus requiring only partial structuring of the area to be
bonded, potentially saving process time. In this experimental study, electrolytically
galvanized steel substrates were partially laser structured to match the shear
stress distribution and then bonded to a carbon fiber-reinforced plastic. The
adhesion properties achieved were characterized using shear tensile tests and
compared with the properties of the fully structured ones. With the partial laser
structuring, a saving of 66 % of the conventional process time was achieved while
maintaining 95 % of the same shear strength.

text: The nonlinear optical response of quantum well excitons is investigated experimentally
using polarization resolved four wave mixing, optical-pump optical-probe, and
optical-pump Terahertz-probe spectroscopy. The four-wave mixing data reveal clear
signatures of coherent biexcitons which concur with straight-forward polarization
selection rules at the Γ point. The type-I samples show the well-established time-domain
beating signatures in the transients as well as the corresponding spectral signatures
clearly. The latter are also present in type-II samples; however, the smaller
exciton and biexciton binding energies in these structures infer longer beating
times which, in turn, are accompanied by faster dephasing of the type-II exciton
coherences. Furthermore, the THz absorption following spectrally narrow, picosecond
excitation at energies in the vicinity of the 1s exciton resonance are discussed.
Here, the optical signatures yield the well-established redshifts and blueshifts
for the appropriate polarization geometries in type-I quantum well samples also
termed “AC Stark Effect”. The THz probe reveals intriguing spectral features which
can be ascribed to coherent negative absorption following an excitation into a
virtual state for an excitation below the 1s exciton resonance. Furthermore, the
scattering and ionization of excitons is discussed for several excitation geometries
yielding control rules for elastic and inelastic quasiparticle collisions.

text: Anomalous currents refer to electronic currents that flow perpendicularly
to the direction of the accelerating electric field. Such anomalous currents can
be generated when Terahertz fields are applied after an optical interband excitation
of GaAs quantum wells. The underlying processes are investigated by numerical
solutions of the semiconductor Bloch equations in the length gauge. Excitonic
effects are included by treating the manybody Coulomb interaction in time-dependent
Hartree-Fock approximation and additionally also carrier-phonon scattering processes
are considered. The band structure and matrix elements are obtained from a 14-band
k · p model within the envelope function approximation. The random phase factors
of the matrix elements that appear due to the separate numerical diagonalization
at each k-point are treated by applying a smooth gauge transformation. We present
the macroscopic Berry curvature and anomalous current transients with and without
excitonic effects. It is demonstrated that the resonant optical excitation of
excitonic resonances can significantly enhance the Berry curvature and the anomalous
currents.

text: The nonlinear optical response of quantum well excitons excited by optical
fields is analyzed by numerical solutions of the semiconductor Bloch equations.
Differential absorption spectra are computed for resonant pumping at the exciton
resonance and the dependence of the absorption changes on the polarization directions
of the pump and probe pulses is investigated. Coherent biexcitonic many-body correlations
are included in our approach up to third-order in the optical fields. Results
are presented for spatially-direct type-I and spatiallyindirect type-II quantum
well systems. Due to the spatial inhomogeneity, in type-II structures a finite
coupling between excitons of opposite spins exists already on the Hartree-Fock
level and contributes to the absorption changes for the case of opposite circularly
polarized pump and probe pulses.

abstract:
- lang: eng
text: We present strong enhancement of third harmonic generation in an amorphous
silicon metasurface consisting of elliptical nano resonators. We show that this
enhancement originates from a new type of multi-mode Fano mechanism. These ‘Super-Fano’
resonances are investigated numerically in great detail using full-wave simulations.
The theoretically predicted behavior of the metasurface is experimentally verified
by linear and nonlinear transmission spectroscopy. Moreover, quantitative nonlinear
measurements are performed, in which an absolute conversion efficiency as high
as ηmax ≈ 2.8 × 10−7 a peak power intensity of 1.2 GW cm−2 is found. Compared
to an unpatterned silicon film of the same thickness amplification factors of
up to ~900 are demonstrated. Our results pave the way to exploiting a strong Fano-type
multi-mode coupling in metasurfaces for high THG in potential applications.

text: Microcellular wood fiber reinforced polymers offer the possibility
to reduce the use of fossil raw materials. In particular, thick-walled structures
with thicknesses greater than 6 mm offer a high potential for weight savings.
This study investigates the cell structures and mechanical properties of injection-molded
test specimens. The influence of different thicknesses (6–10 mm) along with different
chemical blowing agents (endothermic, exothermic) with varying dosages (0–2 wt%)
is analyzed. The investigations reveal that exothermic chemical blowing agents
form finer cells consistently to thin-walled structures than endothermic ones.
Higher foaming agent content leads to higher pore fractions, with many small cells
coalescing into a large open-pore cell network. The mechanical properties depend
mainly on the pore content of the sample. The specific tensile properties deteriorate
with the use of chemical blowing agents (CFA), whereas the sandwich structure
produced with compact edge layers has a positive influence on the specific flexural
properties.

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.
