text: 'ZusammenfassungEine zentrale Aufgabe fachdidaktischer
Forschung stellt die Verbesserung schulischen Unterrichts dar. Die freie Bereitstellung
wirksamer Unterrichtskonzeptionen zur Unterstützung des Selbststudiums von Lehrkräften
bildet eine Strategie für eine flächendeckende Implementierung fachdidaktischer
Innovationen. Allerdings etablieren sich zahlreiche, empirisch erfolgreich evaluierte
Unterrichtskonzeptionen nicht nachhaltig an Schulen. Daher untersucht das vorliegende
Forschungsvorhaben den Implementationsprozess solcher Materialien unter authentischen
Bedingungen. Dazu wurde kriteriengeleitet eine evidenzbasierte, fachdidaktisch
innovative Unterrichtskonzeption ausgewählt: das Münchener Unterrichtskonzept
zur Quantenmechanik (MILQ). Diese wurde den teilnehmenden Lehrkräften fakultativ
zur Verfügung gestellt. Mittels Fallstudien wurde die Implementierung von MILQ
von elf Lehrkräften durch halbstandardisierte Interviews zu Beginn und am Ende
einer Unterrichtsreihe zur Quantenmechanik sowie zwei Unterrichtsbeobachtungen
mit je einem anschließenden stimulated recall explorativ
erfasst. Die Probanden setzten sich überwiegend heuristisch mit MILQ auseinander
und implementierten vor allem Elemente auf Sichtstrukturebene im Unterricht, die
konform zu ihren bisherigen Vorstellungen waren. Dadurch wurde das fachdidaktische
Innovationspotential nicht ausgeschöpft. Bezeichnend ist, dass der empirische
Wirksamkeitsnachweis von MILQ für die Beurteilung der Lehrkräfte nicht relevant
war, was aus theoretischer Sicht bislang als ein zentrales Argument der Bereitstellungsstrategie
zur Implementierung fachdidaktischer Innovation angenommen wurde.'

text: The three-dimensional (3D) distribution of individual atoms on the surface
of catalyst nanoparticles plays a vital role in their activity and stability.
Optimising the performance of electrocatalysts requires atomic-scale information,
but it is difficult to obtain. Here, we use atom probe tomography to elucidate
the 3D structure of 10 nm sized Co2FeO4 and CoFe2O4 nanoparticles during oxygen
evolution reaction (OER). We reveal nanoscale spinodal decomposition in pristine
Co2FeO4. The interfaces of Co-rich and Fe-rich nanodomains of Co2FeO4 become trapping
sites for hydroxyl groups, contributing to a higher OER activity compared to that
of CoFe2O4. However, the activity of Co2FeO4 drops considerably due to concurrent
irreversible transformation towards CoIVO2 and pronounced Fe dissolution. In contrast,
there is negligible elemental redistribution for CoFe2O4 after OER, except for
surface structural transformation towards (FeIII, CoIII)2O3. Overall, our study
provides a unique 3D compositional distribution of mixed Co-Fe spinel oxides,
which gives atomic-scale insights into active sites and the deactivation of electrocatalysts
during OER.

text: Nanostructured manganese oxides have a rich variety of morphologies and crystal
phases which can undergo transformations during synthesis and application. Although
these structural features are crucial for their performance, the mechanisms behind
such transitions are not well understood. Herein, we describe the mechanism of
transformation from layered 2D δ-MnO2 nanosheets to the scarcely reported γ-MnO2
nanocone morphology. Despite the common purpose of introducing Fe dopants to enhance
the conductivity of layered manganese oxides, the Fe galvanic exchange reaction
was found responsible for such coupled phase/morphology transition. Electrochemical
characterization confirmed a distinct electrochemical behaviour of the nanocones,
emphasizing the need to unravel the mechanism of 2D MnO2 transformation. Such
mechanistic insights were gained by systematic and rigorous electron microscopy
studies. The effect of the local chemical composition was determined by energy
dispersive X-ray spectroscopy while electron energy loss spectroscopy unravelled
the key influence of the oxidation state of Mn ions within nanosheets and nanocones.
We propose and demonstrate a Mn2+-mediated oxidative mechanism of coupled morphology/phase
transformation subjected to the equilibrium of Fe and Mn ions during galvanic
exchange reaction. These findings contribute to the understanding of the growth
and morphology/phase transformations of manganese oxide nanostructures, providing
insights for the rational design of nanomaterials.

text: AbstractMany critical codebases are written
in C, and most of them use preprocessor directives to encode variability, effectively
encoding software product lines. These preprocessor directives, however, challenge
any static code analysis. SPLlift, a previously presented approach for analyzing
software product lines, is limited to Java programs that use a rather simple feature
encoding and to analysis problems with a finite and ideally small domain. Other
approaches that allow the analysis of real-world C software product lines use
special-purpose analyses, preventing the reuse of existing analysis infrastructures
and ignoring the progress made by the static analysis community. This work presents
VarAlyzer, a novel static analysis approach for software product
lines. VarAlyzer first transforms preprocessor constructs to
plain C while preserving their variability and semantics. It then solves any given
distributive analysis problem on transformed product lines in a variability-aware
manner. VarAlyzer ’s analysis results are annotated with feature
constraints that encode in which configurations each result holds. Our experiments
with 95 compilation units of OpenSSL show that applying VarAlyzer
enables one to conduct inter-procedural, flow-, field- and context-sensitive data-flow
analyses on entire product lines for the first time, outperforming the product-based
approach for highly-configurable systems.

text: Lithium niobate (LiNbO3), a material frequently used in optical applications,
hosts different kinds of polarons that significantly affect many of its physical
properties. In this study, a variety of electron polarons, namely free, bound,
and bipolarons, are analyzed using first-principles calculations. We perform a
full structural optimization based on density-functional theory for selected intrinsic
defects with special attention to the role of symmetry-breaking distortions that
lower the total energy. The cations hosting the various polarons relax to a different
degree, with a larger relaxation corresponding to a larger gap between the defect
level and the conduction-band edge. The projected density of states reveals that
the polaron states are formerly empty Nb 4d states lowered into the band gap.
Optical absorption spectra are derived within the independent-particle approximation,
corrected by the GW approximation that yields a wider band gap and by including
excitonic effects within the Bethe-Salpeter equation. Comparing the calculated
spectra with the density of states, we find that the defect peak observed in the
optical absorption stems from transitions between the defect level and a continuum
of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity
and other experimentally measurable optical coefficients.

text: In Germany, dual learning programmes are increasingly offered by higher education
institutions. These programmes’ main characteristic and greatest challenge is
their integration of academic and vocational learning. So far, this challenge
has frequently been stated without specifying its exact nature and consequences
for learners. The present study addresses this pedagogical research gap and examines
the extent of variation in the degree of integration among dual study programmes.
With reference to curriculum theory, the study develops an empirical typology
of curricular integration in dual programmes. The data sample consists of 152
programmes at (dual) universities and universities of applied sciences. Data is
analysed using hierarchical cluster analysis. Results indicate that the currently
prevailing forms of curricular integration should best be differentiated according
to five types. The five overlapping types of integration are located on a continuum
ranging from parallelism through organisational linking to full curricular integration
targeted immediately at students’ personal integration. The analysis confirms
that there are problems with complying with integration standards set on the policy
level. Above all, the study offers new insights on what marks the diverse integration
landscape of dual study programmes. It proves that approaches to integration are
more differentiated than previous research has shown.
