text: "Lead-containing piezoelectric ceramics are still the base for today’s ultrasonic
transducers used in broad applications. This is partly due to missing powerful
lead-free piezoelectric ceramic parts in the commercial market. There has been
much research on lead-free materials but developing them into marketable parts
seems to be an ongoing process. The actual exemption of ROHS has expired, but
as the new exemption has already been requested, ceramic suppliers keep on selling
lead containing products. Nevertheless, these should be replaced by lead-free
alternatives for environmental and health issues. \r\nThis contribution focuses
on exploring the technological readiness level of lead-free hard piezoceramics
for prestressed ultrasonic transducers. A small series of bolted Langevin transducers
was set up with standard PZT material and three commercial lead-free variants.
Results of the building process from individual ring ceramic characteristics to
transducer load tests are presented. The main finding of this study is that the
lead-free materials technically can compete with the standard PZT for medium-power
applications. Some adaptations in the ultrasonic system must be done: the geometry
must be altered to fit resonance frequency, and higher voltages or thinner ceramics
are needed to achieve the same vibration level at low load. For reaching same
power, the volume of lead-free ceramics must be 1.5 to 3 times larger. As already
promoted in literature, mechanical losses at high vibration levels are smaller
for the lead-free materials. This might help to argument lead-free piezoelectric
materials in some applications.\r\n\r\nReferences\r\n1.\tDirective 2011/65/EU

text: Abstract Polymer-derived silicon oxycarbide ceramics (SiCO) have been considered
as potential anode materials for lithium- and sodium-ion batteries. To understand
their electrochemical storage behavior, detailed insights into structural sites
present in SiCO are required. In this work, the study of local structures in SiCO
ceramics containing different amounts of carbon is presented. 13C and 29Si solid-state
MAS?NMR spectroscopy combined with DFT calculations, atomistic modeling, and EPR
investigations, suggest significant changes in the local structures of SiCO ceramics
even by small changes in the material composition. The provided findings on SiCO
structures will contribute to the research field of polymer-derived ceramics,
especially to understand electrochemical storage processes of alkali metal/ions
such as Na/Na+ inside such networks in the future.

text: AbstractPure iron is very attractive as a
biodegradable implant material due to its high biocompatibility. In combination
with additive manufacturing, which facilitates great flexibility of the implant
design, it is possible to selectively adjust the microstructure of the material
in the process, thereby control the corrosion and fatigue behavior. In the present
study, conventional hot-rolled (HR) pure iron is compared to pure iron manufactured
by electron beam melting (EBM). The microstructure, the corrosion behavior and
the fatigue properties were studied comprehensively. The investigated sample conditions
showed significant differences in the microstructures that led to changes in corrosion
and fatigue properties. The EBM iron showed significantly lower fatigue strength
compared to the HR iron. These different fatigue responses were observed under
purely mechanical loading as well as with superimposed corrosion influence and
are summarized in a model that describes the underlying failure mechanisms.

text: 'The 3D shear deformation and failure behaviour of a glass fibre reinforced
polypropylene in a shear strain rate range of γ˙=2.2×10−4 to 3.4 1s is investigated.
An Iosipescu testing setup on a servo-hydraulic high speed testing unit is used
to experimentally characterise the in-plane and out-of-plane behaviour utilising
three specimen configurations (12-, 13- and 31-direction). The experimental procedure
as well as the testing results are presented and discussed. The measured shear
stress–shear strain relations indicate a highly nonlinear behaviour and a distinct
rate dependency. Two methods are investigated to derive according material characteristics:
a classical engineering approach based on moduli and strengths and a data driven
approach based on the curve progression. In all cases a Johnson–Cook based formulation
is used to describe rate dependency. The analysis methodologies as well as the
derived model parameters are described and discussed in detail. It is shown that
a phenomenologically enhanced regression can be used to obtain material characteristics
for a generalising constitutive model based on the data driven approach.'

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: Wood–plastic composites (WPC) are enjoying a steady increase in popularity.
In addition to the extrusion of decking boards, the material is also used increasingly
in injection molding. Depending on the formulation, geometry and process parameters,
WPC tends to exhibit irregular filling behavior, similar to the processing of
thermosets. In this work, the influence of matrix material and wood fiber content
on the flow, mold filling and segregation behavior of WPC is analyzed. For this
purpose, investigations were carried out on a flow spiral and a sheet cavity.
WPC based on thermoplastic polyurethane (TPU) achieves significantly higher flow
path lengths at a wood mass content of 30% than polypropylene (PP)-based WPC.
The opposite behavior occurs at higher wood contents due to the different shear
thinning behavior. Slightly decreased wood contents could be observed at the beginning
of the flow path and greatly increased wood contents at the end of the flow path,
compared to the starting material. When using the plate cavity, flow anomalies
in the form of free jets occur as a function of the wood content, with TPU exhibiting
the more critical behavior. The flow front is frayed, but in contrast to the flow
spiral, no significant wood accumulation could be detected due to the shorter
flow path lengths.

text: Carbon fiber reinforced plastics (CFRPs) gained high interest in industrial
applications because of their excellent strength and low specific weight. The
stacking sequence of the unidirectional plies forming a CFRP laminate, and their
thicknesses, primarily determine the mechanical performance. However, during manufacturing,
defects, e.g., pores and residual stresses, are induced, both affecting the mechanical
properties. The objective of the present work is to accurately measure residual
stresses in CFRPs as well as to investigate the effects of stacking sequence,
overall laminate thickness, and the presence of pores on the residual stress state.
Residual stresses were measured through the incremental hole-drilling method (HDM).
Adequate procedures have been applied to evaluate the residual stresses for orthotropic
materials, including calculating the calibration coefficients through finite element
analysis (FEA) based on stacking sequence, laminate thickness and mechanical properties.
Using optical microscopy (OM) and computed tomography (CT), profound insights
into the cross-sectional and three-dimensional microstructure, e.g., location
and shape of process-induced pores, were obtained. This microstructural information
allowed for a comprehensive understanding of the experimentally determined strain
and stress results, particularly at the transition zone between the individual
plies. The effect of pores on residual stresses was investigated by considering
pores to calculate the calibration coefficients at a depth of 0.06 mm to 0.12
mm in the model and utilizing these results for residual stress evaluation. A
maximum difference of 46% in stress between defect-free and porous material sample
conditions was observed at a hole depth of 0.65 mm. The significance of employing
correctly calculated coefficients for the residual stress evaluation is highlighted
by mechanical validation tests.

text: The corrosion behavior of a hybrid material consisting of intrinsically bonded
carbon fiber-reinforced epoxy resin with laser-structured EN AW 6082 metal was
investigated. Particular attention was paid to the effects of the laser-structuring,
surface topography and the contacting. Pristine and hybridized specimens were
corroded in aqueous NaCl electrolyte (0.1 mol/l) using a potentiodynamic polarization
technique and subsequently analyzed using computed tomography, scanning electron-,
light- and laser scanning microscopy. The results show that the corrosive reaction
arises mainly from the aluminum component. Surface pretreatment of the aluminum
resulted in increasing corrosion rates, but showed no influence on the hybrids
corrosion properties. Optical micrographs suggest that the epoxy resin acts as
a sealant preventing galvanic corrosion between the aluminum and carbon fibers
by hindering the diffusion of the electrolyte into the joints. While corrosion
effects were observed locally at the aluminum surface, they were, contrary to
expectations, not enhanced on the hybrid interfaces.

text: Wood fiber reinforcement of plastics is almost limited to polypropylene,
polyethylene, polyvinyl chloride and polystyrene. Wood fiber reinforcement of
thermoplastic polyurethanes (TPU) is a new research field and paltry studied scientifically.
Wood fiber reinforcement can carry out synergistic effects between sustainability,
material or product price reduction, improved mechanical properties at high elongation,
and brilliant appearance and haptics. In order to evaluate to what extent the
improvement of mechanical properties depend on material-specific parameters (fiber
type, fiber content) and on process-specific parameters (holding pressure, temperature
control and injection speed), differently filled compounds were injection molded
according to a partial factorial test plan and subjected to characterizing test
procedures (tensile test, Shore hardness and notched impact test). Tensile strength
showed significant dependence on barrel temperature, fiber type and interaction
between holding pressure and barrel temperature in the region of interest. Young’s
modulus can be influenced by fiber content but not by fiber type. Notched impact
strength showed a significant influence of cylinder temperature, fiber content,
fiber type and the interaction between cylinder temperature and fiber content
in the region of interest. Shore hardness is related to fiber content and the
interaction between mold temperature and injection flow rate. Our results show
not only that wood-filled TPU can be processed very well by injection molding,
but also that the mechanical properties depend significantly on temperature control
in the injection-molding process. Moreover, considering the significant reinforcing
effect of the wood fibers, a good fiber-matrix adhesion can be assumed.
