text: In order to follow the 1.5 degree path of the Paris Climate Agreement, drastic
greenhouse gas reduction measures are needed in the transport sector. The potential
of public transport and new mobility services to reduce transport-related greenhouse
gas emissions cannot yet be fully exploited, especially in rural regions. This
paper presents the concept of an innovative mobility system, called NeMo.bil,
that intends to fill the gap between individual and public transport to create
a demand-oriented and sustainable mobility offer. The concept is based on convoy
formation of autonomously driving lightweight vehicles serving the first and last
mile and a larger towing vehicle carrying enough power and energy to move the
convoy over longer distances at higher speeds. This combination of two different
vehicles, intelligently controlled by a digital ecosystem, aims to significantly
increasing energy, resource and cost efficiency. Based on an analysis of previous
approaches for innovative mobility solutions, the concept is derived from a technical
and sociological perspective and its potential for reducing energy demand is calculated.

text: Laser additive manufacturing processes are used for the production
of highly complex geometric structures due to their high geometric freedom. Additive
manufacturing processes, in particular powder-based selective laser melting, are
used to produce metallic additive manufactured components for the automotive and
aerospace industries. Different materials are often joined together to realize
sustainable lightweight construction. The production of such mixed construction
joints is often realized using mechanical joining technology (e.g. self-piercing
riveting). However, there is currently very little experience with the mechanical
joining of metallic additive manufacturing components. Furthermore, there is insufficient
knowledge about the effects that occur during the mechanical joining of additive
manufacturing components. In this article, a method is presented to investigate
the joinability of additively manufactured components with conventionally manufactured
components using a numerical simulation of the self-piercing riveting process.
For this purpose, the additive manufacturing materials are characterized experimentally,
the simulation model is configured, and the joining process with additive manufacturing
materials is represented in the numerical simulation. Furthermore, the influence
of the building direction on the mechanical properties is shown using miniature
tensile specimens. Besides the configuration of the simulation model, the influence
of heat treatment on the self-piercing riveting process is presented.

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: Abstract. In order to reduce global energy consumption in production
and industry along with the associated CO2 emissions, existing resources must
be used more efficiently. This includes the energy-efficient and comprehensive
recycling of a wide range of metals. Especially for the production of aluminium,
there is a large potential for saving energy using efficient recycling processes.
With regard to the recycling of aluminium studies have shown that solid-state
recycling processes are significantly more efficient considering the used energy
and resources compared to the conventional, smelting-metallurgical recycling process.
In this paper, the direct and energy-efficient friction-induced recycling process
(FIRP) based on the conform process is further described and analysed in terms
of the temperature-property relationships. For this purpose, the influence of
the processing temperature on the microstructure and properties of the recycled
semi-finished products is investigated using the toll system that enables an ECAP
forming. Specific sections of the (in theory) infinite, recycled semi-finished
product are taken and analysed at different process temperatures of the solid
state recycling process. Based on these sections, the properties in terms of mechanical
hardness, strength, ductility and grain size are analysed and a degressive relationship
between process temperature and mechanical hardness up to a temperature of 270
°C can be shown. Applying the Hall-Petch relationship, it is analysed whether
there is a correlation between the strength and the microstructure in the form
of the grain size.

text: Die Wirtschaftlichkeit von Wärmemotoren wird maßgeblich durch die Rückführung
von Wärme in Rekuperatoren beeinflusst. Beim isobaren Expansionsmotor vom Bush-Typ,
einem Wärmemotor, welcher bereits mit Wärmequellen ab 60°C betrieben werden kann,
steigt der thermische Wirkungsgrad durch den Einsatz von Rekuperatoren signifikant.
Gleichzeitig wirken sich das Fluidvolumen des Wärmeübertragers sowie der beim
Betrieb auftretende Druckverlust negativ auf den thermischen Wirkungsrad aus.
In dieser Arbeit wird der Zusammenhang von Totvolumen, Druckverlust und Wärmerückgewinnung
untersucht und Empfehlungen für den Betrieb von Rekuperatoren am isobaren Expansionsmotor
gegeben.

text: "AbstractThe use of structured measuring
systems to prevent wall slip is a common approach to obtain absolute rheological
values. Typically, only the minimum distance between the measuring surfaces is
used for further calculation, implying that no flow occurs between the structural
elements. But this assumption is misleading, and a gap correction is necessary.
To determine the radius correction $$\\Delta
r$$\r\n
\ \r\n Δ\r\n r\r\n
\ \r\n
for specific geometries, we conducted investigations on three Newtonian fluids
(two silicon oils and one suspension considered to be Newtonian in the relevant
shear rate range). The results show that $$\\Delta
r$$\r\n
\ \r\n Δ\r\n r\r\n
\ \r\n
is not only shear- and material-independent, but geometry-dependent, providing
a Newtonian flow behaviour in a similar viscosity range. Therefore, a correction
value can be determined with only minute deviations in different Newtonian fluids.
As the conducted laboratory measurements are very time-consuming and expensive,
a CFD-approach with only very small deviations was additionally developed and
compared for validation purposes. Therefore, simulation is an effective and resource-efficient
alternative to the presented laboratory measurements to determine $$\\Delta
r$$\r\n
\ \r\n Δ\r\n r\r\n
\ \r\n
for the correction of structured coaxial geometries even for non-Newtonian fluids
in the future."

text: "We study how competition between physicians affects the provision of medical
care. In\r\nour theoretical model, physicians are faced with a heterogeneous patient
population, in which patients\r\nsystematically vary with regard to both their
responsiveness to the provided quality of care and their\r\nstate of health. We
test the behavioral predictions derived from this model in a controlled laboratory\r\nexperiment.
In line with the model, we observe that competition significantly improves patient
benefits\r\nas long as patients are able to respond to the quality provided. For
those patients, who are not able\r\nto choose a physician, competition even decreases
the patient benefit compared to a situation without\r\ncompetition. This decrease
is in contrast to our theoretical prediction implying no change in benefits for\r\npassive
patients. Deviations from patient-optimal treatment are highest for passive patients
in need of\r\na low quantity of medical services. With repetition, both, the positive
effects of competition for active\r\npatients as well as the negative effects
of competition for passive patients become more pronounced. Our\r\nresults imply
that competition can not only improve but also worsen patient outcome and that
patients’\r\nresponsiveness to quality is decisive."

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: Abstract. Friction-spinning as an innovative incremental forming process
enables large degrees of deformation in tube and sheet metal-forming due to a
self-induced heat generation in the forming zone. This paper presents new process
designs for energy and resource-efficient forming of gas cylinders by friction-spinning
without the use of an external heat supply. The self-generated heat enables friction-spinning
process to reduce the energy demand in the manufacture of gas cylinders, which
are usually manufactured with external heat (mostly fossil fuels), by 95 %. Typical
gas cylinder contours, such as flattened and spherical bottom ends and cylinder
necks, are manufactured by friction-spinning of AW 6060 tubular profiles with
specifically designed tool path strategies. It is shown that friction-spinning
enables the manufacture of typical gas cylinder contours with sufficient wall
thickness and the required gas tightness without the input of external heat. Thus,
this process can contribute to an increase in the energy and resource efficiency
of forming processes.

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: "Die für die Berechnung des Energieeffizienzindex von Haushaltskältegeräten
benötigten Parameter werden durch Norm-Messungen im Neuzustand der Geräte bestimmt.
Aus früheren Untersuchungen ist bekannt, dass durch verschiedene technische Alterungsmechanismen
der Energieverbrauch über eine Produktlebensdauer von 18 Jahren um bis zu 33 %
zunehmen kann. Ziel des vom BMWi geförderten Projekts ALGE war es, die verschie-denen
Ursachen und Einflussgrößen für die Alterung von Haushaltskältegeräten zu ermitteln
und eine Alterungs-funktion zu bestimmen, die den zeitlichen Verlauf des zunehmenden
Energieverbrauchs beschreibt.\r\nIn diesem Projekt wurde das Alterungsverhalten
von Haushaltskältegeräten durch 100 Normenergieverbrauchs-messungen an 32 real
gealterten Geräten untersucht. Aus den gewonnenen Ergebnissen konnte eine Alterungs-funktion
bestimmt werden, die den Anstieg des Energieverbrauchs beschreibt. Alle untersuchten
Geräte wurden an der Universität Paderborn im Neuzustand vermessen und nach einer
Laufzeit von bis zu 21 Jahren erneut geprüft. Bereits nach einem zweijährigen
Betrieb konnte ein Mehrverbrauch von bis zu 11 % festgestellt werden. Über die
durchschnittliche Produktlebensdauer von Haushaltskältegeräten von ca. 16 Jahren
steigert sich der Energieverbrauch um durchschnittlich 27 %.\r\nIm Rahmen des
Projekts wurden verschiedene Systemkomponenten, wie Isolierung und Verdichter,
hinsichtlich ihres Alterungsverhaltens untersucht. Bei dem im Gehäuse als Isolierung
verwendeten PUR-Schaum konnte über einen Zeitraum von 31 Monaten ein Anstieg der
Wärmeleitfähigkeit von 19,5 W/(m⋅K) auf 24,5 W/(m⋅K) festge-stellt werden. Zur
Untersuchung der Alterung der Verdichter wurden zuvor auf einem Kalorimeterteststand
ver-messene Verdichter in Geräte eingebaut. Nach einem zweijährigen Betrieb wurden
diese Verdichter wieder aus-gebaut und erneut vermessen. Hierbei konnte keine
Änderung des COP festgestellt werden. Zusätzlich zu den technischen Parametern
wurde der Einfluss des Verbraucherverhaltens analysiert. Hier zeigte sich, dass
bis zu 33 % des Gesamtenergieverbrauchs nach einer mehrjährigen Nutzungsdauer
verbraucherinduziert sein können."

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."
