text: A two-step seeded-growth method was refined to synthesize Au@Pd core@shell
nanoparticles with thin Pd shells, which were then deposited onto alumina to obtain
a supported Au@Pd/Al2O3 catalyst active for prototypical CO oxidation. By the
strict control of temperature and Pd/Au molar ratio and the use of l-ascorbic
acid for making both Au cores and Pd shells, a 1.5 nm Pd layer is formed around
the Au core, as evidenced by transmission electron microscopy and energy-dispersive
spectroscopy. The core@shell structure and the Pd shell remain intact upon deposition
onto alumina and after being used for CO oxidation, as revealed by additional
X-ray diffraction and X-ray photoemission spectroscopy before and after the reaction.
The Pd shell surface was characterized with in situ infrared (IR) spectroscopy
using CO as a chemical probe during CO adsorption–desorption. The IR bands for
CO ad-species on the Pd shell suggest that the shell exposes mostly low-index
surfaces, likely Pd(111) as the majority facet. Generally, the IR bands are blue-shifted
as compared to conventional Pd/alumina catalysts, which may be due to the different
support materials for Pd, Au versus Al2O3, and/or less strain of the Pd shell.
Frequencies obtained from density functional calculations suggest the latter to
be significant. Further, the catalytic CO oxidation ignition-extinction processes
were followed by in situ IR, which shows the common CO poisoning and kinetic behavior
associated with competitive adsorption of CO and O2 that is typically observed
for noble metal catalysts.

text: The proton conductivity of two coordination networks, [Mg(H2O)2(H3L)]·H2O
and [Pb2(HL)]·H2O (H5L
= (H2O3PCH2)2-NCH2-C6H4-SO3H),
is investigated by AC impedance spectroscopy. Both materials contain the same
phosphonato-sulfonate linker molecule, but have clearly different crystal structures,
which has a strong effect on proton conductivity. In the Mg-based coordination
network, dangling sulfonate groups are part of an extended hydrogen bonding network,
facilitating a “proton hopping” with low activation energy; the material shows
a moderate proton conductivity. In the Pb-based metal-organic framework, in contrast,
no extended hydrogen bonding occurs, as the sulfonate groups coordinate to Pb2+,
without forming hydrogen bonds; the proton conductivity is much lower in this
material.

text: In view of economic and ecological trends, the concepts for lightweight construction
in transport systems are becoming increasingly important. These are frequently
applied in the form of multi-material systems, which are characterized by the
selective use of materials and geometries. One major challenge in the manufacturing
of multi-material systems is the joining of the individual components to form
a complete system. Mechanical joining processes such as semi-tubular self-piercing
riveting are frequently used for this application but reach their limits concerning
the number of combinations of geometry and material. In order to react to the
requirements and to increase the versatility of semi-tubular self-pierce riveting,
a process combination consisting of a tumbling process and a self-pierce riveting
process has been presented previously. This process combination is used in this
work to investigate the versatility and to identify the influencing parameters
on it. For this purpose, experiments are conducted to identify process-side influence
possibilities. The tests are performed with a dual-phase steel aluminum alloy
to represent the varying mechanical characteristics of multi-material systems.
Furthermore, the initial sheet thicknesses of the joining partners are varied
in several steps. In addition to the geometric joint formation used to describe
the undercut, the rivet head end position and the residual sheet thickness, the
joining process, is also analyzed during the investigations. Further, the innovative
joining process is evaluated by comparing it with a conventional self-piercing
riveting process. The knowledge obtained represents a basis for the identification
and evaluation of the versatility of the process combination.

text: AbstractPolarons influence decisively the
performance of lithium niobate for optical applications. In this work, the formation
of (defect) bound polarons in lithium niobate is studied by ab initio molecular
dynamics. The calculations show a broad scatter of polaron formation times. Rising
temperature increases the share of trajectories with long formation times, which
leads to an overall increase of the average formation time with temperature. However,
even at elevated temperatures, the average formation time does not exceed the
value of 100 femtoseconds, i.e., a value close to the time measured for free,
i.e., self-trapped polarons. Analyzing individual trajectories, it is found that
the time required for the structural relaxation of the polarons depends sensitively
on the excitation of the lithium niobate high-frequency phonon modes and their
phase relation.

joining process, is also analyzed during the investigations. Further, the innovative
joining process is evaluated by comparing it with a conventional self-piercing
riveting process. The knowledge obtained represents a basis for the identification
and evaluation of the versatility of the process combination.

text: The adaptive joining process employing friction-spun joint connectors
(FSJC) is a promising method for the realization of adaptable joints and thus
for lightweight construction. In addition to experimental investigations, numerical
studies are indispensable tools for its development. Therefore, this paper includes
an analysis of boundary conditions for the spatial discretization and mesh modeling
techniques, the material modeling, the contact and friction modeling, and the
thermal boundary conditions for the finite element (FE) modeling of this joining
process. For these investigations, two FE models corresponding to the two process
steps were set up and compared with the two related processes of friction stir
welding and friction drilling. Regarding the spatial discretization, the Lagrangian
approach is not sufficient to represent the deformation that occurs. The Johnson-Cook
model is well suited as a material model. The modeling of the contact detection
and friction are important research subjects. Coulomb’s law of friction is not
adequate to account for the complex friction phenomena of the adaptive joining
process. The thermal boundary conditions play a decisive role in heat generation
and thus in the material flow of the process. It is advisable to use temperature-dependent
parameters and to investigate in detail the influence of radiation in the entire
process.

text: Mechanical joining processes are an essential part of modern lightweight construction.
They permit materials of different types to be joined in a way that is suitable
for the loads involved. These processes reach their limits, however, as soon as
the boundary conditions change. In most cases, these elements are specially adapted
to the joining point and cannot be used universally. Changes require cost-intensive
adaptation of both the element and the process control, thus making production
more complex. This results in high costs due to the increased number of auxiliary
joining element variants required and reduces the economic efficiency of mechanical
joining. One approach to overcoming this issue is the use of adaptive auxiliary
joining elements formed by friction spinning. This article presents the current
state of research on pre-hole-free joining with adaptive joining elements. The
overall process chain is illustrated, explained and analyzed. Special attention
is paid to demonstrating the feasibility of pre-hole-free joining with adaptive
joining elements. The chosen mechanical parameters are subsequently listed. Finally,
a comprehensive outlook of the future development potential is derived.

text: Crack growth in structures depends on the cyclic loads applied on it, such
as mechanical, thermal and contact, as well as residual stresses, etc. To provide
an accurate simulation of crack growth in structures, it is of high importance
to integrate all kinds of loading situations in the simulations. Adapcrack3D is
a simulation program that can accurately predict the propagation of cracks in
real structures. However, until now, this three-dimensional program has only considered
mechanical loads and static thermal loads. Therefore, the features of Adapcrack3D
have been extended by including contact loading in crack growth simulations. The
numerical simulation of crack propagation with Adapcrack3D is generally carried
out using FE models of structures provided by the user. For simulating models
with contact loading situations, Adapcrack3D has been updated to work with FE
models containing multiple parts and necessary features such as coupling and surface
interactions. Because Adapcrack3D uses the submodel technique for fracture mechanical
evaluations, the architecture of the submodel is also modified to simulate models
with contact definitions between the crack surfaces. This paper discusses the
newly implemented attribute of the program with the help of illustrative examples.
The results confirm that the contact simulation in Adapcrack3D is a major step
in improving the functionality of the program.

text: Friction-spinning as an innovative incremental forming process enables
large degrees of deformation in the field of tube and sheet metal forming due
to a self-induced heat generation in the forming zone. This paper presents a new
tool and process design with a driven tool for the targeted adjustment of residual
stress distributions in the friction-spinning process. Locally adapted residual
stress depth distributions are intended to improve the functionality of the friction-spinning
workpieces, e.g. by delaying failure or triggering it in a defined way. The new
process designs with the driven tool and a subsequent flow-forming operation are
investigated regarding the influence on the residual stress depth distributions
compared to those of standard friction-spinning process. Residual stress depth
distributions are measured with the incremental hole-drilling method. The workpieces
(tubular part with a flange) are manufactured using heat-treatable 3.3206 (EN-AW
6060 T6) tubular profiles. It is shown that the residual stress depth distributions
change significantly due to the new process designs, which offers new potentials
for the targeted adjustment of residual stresses that serve to improve the workpiece
properties.

text: Friction-spinning as an innovative incremental forming process enables
high degrees of deformation in the field of tube and sheet metal forming due to
self-induced heat generation in the forming area. The complex thermomechanical
conditions generate non-uniform residual stress distributions. In order to specifically
adjust these residual stress distributions, the influence of different process
parameters on residual stress distributions in flanges formed by the friction-spinning
of tubes is investigated using the design of experiments (DoE) method. The feed
rate with an effect of −156 MPa/mm is the dominating control parameter for residual
stress depth distribution in steel flange forming, whereas the rotation speed
of the workpiece with an effect of 18 MPa/mm dominates the gradient of residual
stress generation in the aluminium flange-forming process. A run-to-run predictive
control system for the specific adjustment of residual stress distributions is
proposed and validated. The predictive model provides an initial solution in the
form of a parameter set, and the controlled feedback iteratively approaches the
target value with new parameter sets recalculated on the basis of the deviation
of the previous run. Residual stress measurements are carried out using the hole-drilling
method and X-ray diffraction by the cosα-method.
