text: Eine Forderung nach evidenzbasierter Praxis (EBP) im Bildungswesen kann sowohl
vor dem Hintergrund der Bedeutung wissenschaftlicher Evidenzen innerhalb gesellschaftlicher
Diskurse als auch der Evidenzbasierung in anderen Bereichen formuliert werden.
Der Umgang mit und die Bewertung von Evidenzen stellen somit vor dem Hintergrund
epistemologischer Überzeugungen relevante Aufgaben für den Chemieunterricht dar.
Dabei ist unklar, inwiefern (angehende) Lehrkräfte über Kompetenzen in EBP verfügen.
Bestehende Studien weisen auf einen Bedarf der fachdidaktischen Analyse und Förderung
von Kompetenzen in EBP bei angehenden Lehrkräften hin.Im Rahmen dieser Dissertation
wurde die Domänenspezifität der Kompetenzen in EBP sowie deren Förderung in einem
fachdidaktischen Kontext untersucht. Dabei wurde ein weiterer Schwerpunkt auf
den Umgang mit anomalen Beobachtungen im Sinne widersprüchlicher Evidenzen gelegt.
Innerhalb von drei Teilstudien wurden unterschiedliche methodische Zugänge zur
Kompetenz in EBP auf Grundlage epistemologischer Überzeugungen gewählt.Die Ergebnisse
weisen auf einen Förderbedarf der Kompetenz in EBP für angehende Lehrkräfte aller
Unterrichtsfächer hin. Eine entwickelte Intervention für angehende Chemielehrkräfte
weist eine Wirksamkeit zur Förderung von Kompetenzen in EBP auf. Im Rahmen einer
Modellierungsstudie kann der Einfluss von Fachwissen sowie Indizien für einen
Einfluss epistemologischer Überzeugungen auf den Umgang mit anomalen Beobachtungen
gezeigt werden.

text: The role of evidence based practice (EBP) in educational contexts can be argued
from the necessity ofevidence for societal debates, as well as evidence based
practice in other research fields, such asmedicine. Therefore, using evidence
based on epistemological beliefs is a relevant task for scienceeducation. However,
i t is unclear whether pre service teachers hold necessary competences in EBP.Existing
research indicates a need for the analysis and promotion of competences in EBP
for pre serviceteachers from a scien ce education perspective.This project aims
at investigating the domainspecificity and promotion of competences in EBP of
preservice teachers. An additional emphasis is put on the reaction to anomalous
observations ascontradictory evidence. Within three sub studies, different methodological
approaches were used togather insights into the competence in EBP from the base
of epistemological beliefs.As results show, there is a need for promotion in competences
in EBP for preservice teachers in allsubjects. Therefore, the developed intervention
for the promotion of pre service chemistry teacherscompetence in EBP shows to
be effective. Moreover, the impact of content knowledge and the role ofepistemological
beliefs on the interpretation of anomalous observations could be demonstrated.

text: This article presents the potential-dependent adsorption of two proteins,
bovine serum albumin (BSA) and lysozyme (LYZ), on Ti6Al4V alloy at pH 7.4 and
37 °C. The adsorption process was studied on an electropolished alloy under cathodic
and anodic overpotentials, compared to the open circuit potential (OCP). To analyze
the adsorption process, various complementary interface analytical techniques
were employed, including PM-IRRAS (polarization-modulation infrared reflection-absorption
spectroscopy), AFM (atomic force microscopy), XPS (X-ray photoelectron spectroscopy),
and E-QCM (electrochemical quartz crystal microbalance) measurements. The polarization
experiments were conducted within a potential range where charging of the electric
double layer dominates, and Faradaic currents can be disregarded. The findings
highlight the significant influence of the interfacial charge distribution on
the adsorption of BSA and LYZ onto the alloy surface. Furthermore, electrochemical
analysis of the protein layers formed under applied overpotentials demonstrated
improved corrosion protection properties. These studies provide valuable insights
into protein adsorption on titanium alloys under physiological conditions, characterized
by varying potentials of the passive alloy.

text: Photoactive chromium(III) complexes saw a conceptual breakthrough with the
discovery of the prototypical molecular ruby mer-[Cr(ddpd)2]3+ (ddpd = N,N′-dimethyl-N,N′-dipyridin-2-ylpyridine-2,6-diamine),
which shows intense long-lived near-infrared (NIR) phosphorescence from metal-centered
spin-flip states. In contrast to the numerous studies on chromium(III) photophysics,
only 10 luminescent molybdenum(III) complexes have been reported so far. Here,
we present the synthesis and characterization of mer-MoX3(ddpd) (1, X = Cl; 2,
X = Br) and cisfac-[Mo(ddpd)2]3+ (cisfac-[3]3+), an isomeric heavy homologue of
the prototypical molecular ruby. For cisfac-[3]3+, we found strong zero-field
splitting using magnetic susceptibility measurements and electron paramagnetic
resonance spectroscopy. Electronic spectra covering the spin-forbidden transitions
show that the spin-flip states in mer-1, mer-2, and cisfac-[3]3+ are much lower
in energy than those in comparable chromium(III) compounds. While all three complexes
show weak spin-flip phosphorescence in NIR-II, the emission of cisfac-[3]3+ peaking
at 1550 nm is particularly low in energy. Femtosecond transient absorption spectroscopy
reveals a short excited-state lifetime of 1.4 ns, 6 orders of magnitude shorter
than that of mer-[Cr(ddpd)2]3+. Using density functional theory and ab initio
multireference calculations, we break down the reasons for this disparity and
derive principles for the design of future stable photoactive molybdenum(III)
complexes.

text: AbstractCoating medical implants with antibacterial
polymers may prevent postoperative infections which are a common issue for conventional
titanium implants and can even lead to implant failure. Easily applicable diblock
copolymers are presented that form polymer brushes via “grafting to” mechanism
on titanium and equip the modified material with antibacterial properties. The
polymers carry quaternized pyridinium units to combat bacteria and phosphonic
acid groups which allow the linear chains to be anchored to metal surfaces in
a convenient coating process. The polymers are synthesized via reversible‐addition‐fragmentation‐chain‐transfer
(RAFT) polymerization and postmodifications and are characterized using NMR spectroscopy
and SEC. Low grafting densities are a major drawback of the “grafting to” approach
compared to “grafting from”. Thus, the number of phosphonic acid groups in the
anchor block are varied to investigate and optimize the surface binding. Modified
titanium surfaces are examined regarding their composition, wetting behavior,
streaming potential, and coating stability. Evaluation of the antimicrobial properties
revealed reduced bacterial adhesion and biofilm formation for certain polymers,
albeit the cell biocompatibility against human gingival fibroblasts is also impaired.
The presented findings show the potential of easy‐to‐apply polymer coatings and
aid in designing next‐generation implant surface modifications.

text: The Knoevenagel reaction is a classic reaction in organic chemistry
for the formation of C-C bonds. In this study, various catalytic monomers for
Knoevenagel reactions were synthesized and polymerized via photolithography to
form polymeric gel dots with a composition of 90% catalyst, 9% gelling agent and
1% crosslinker. Furthermore, these gel dots were inserted into a microfluidic
reactor (MFR) and the conversion of the reaction using gel dots as catalysts in
the MFR for 8 h at room temperature was studied. The gel dots containing primary
amines showed a better conversion of about 83–90% with aliphatic aldehyde and
86–100% with aromatic aldehyde, compared to the tertiary amines (52–59% with aliphatic
aldehyde and 77–93% with aromatic aldehydes) which resembles the reactivity of
the amines. Moreover, the addition of polar solvent (water) in the reaction mixture
and the swelling properties of the gel dots by altering the polymer backbone showed
a significant enhancement in the conversion of the reaction, due to the increased
accessibility of the catalytic sites in the polymeric network. These results suggested
the primary-amine-based catalysts facilitate better conversion compared to tertiary
amines and the reaction solvent had a significant influence on organocatalysis
to improve the efficiency of MFR.

text: Im Rahmen dieser Dissertation wurden Katalysatoren, welche auf der thermischen
Zersetzung von metallorganischen Gerüstverbindungen basieren, mittels Röntgenabsorptionsspektroskopie
(XAS) und Röntgenemissionsspektroskopie (XES) untersucht. Durch diesen synthetischen
Ansatz können hochdisperse Ni-basierte Katalysatoren eingebettet in einer Kohlenstoffmatrix
gewonnen werden, welche für die Methanisierung von CO2 Einsatz finden. Diese sollen
eine hohe Stabilität gegenüber Wasserstoffausfällen aufweisen, welche bedingt
durch Wetterfluktuationen in der Gewinnung von grünem Wasserstoff auftreten. Um
ein derartiges System gezielt gestalten zu können, ist ein detailliertes Verständnis
zugrundeliegender chemischer Mechanismen und damit einhergehend elektronischer
Strukturen der Katalysatorsysteme notwendig. Durch die detaillierte Analyse der
Katalysator-Vorstufen mittels XAS konnte gezeigt werden, dass auch unter reduktiven
Bedingungen in der thermischen Zersetzung Spuren von Ni(II) vorliegen und keine
reine Nifcc-Struktur erreicht werden konnte. Eine detaillierte Auswertung der
gleichen Präkatalysatoren mittels XES konnte durch eine neuartige Kombination
von HERFD-XANES, theoretischer Berechnungen und VtC-XES einen eindeutigen Beweis
für das Vorhandensein der gewünschten Kohlenstoffmatrix sowie Spuren von NiO im
Präkatalysator liefern, welche sich vorteilhaft auf die spätere Aktivität im finalen
Katalysator auswirken. Abschließend konnte mittels einer in-situ Untersuchung
der Temperaturbereich, in dem sich die aktive Katalysatorspezies ausbildet, auf
80 bis 200 C eingegrenzt werden. Schließlich konnte ein eindeutiger Zusammenhang
zwischen dem Verlust einer stabilisierenden Kohlenstoffschicht und einem Rückgang
der Aktivität belegt werden.

text: This work aimed to establish methods based on X-ray absorption (XAS) and emission
spectroscopy (XES) to study Ni-based catalysts obtained by the thermal decomposition
of metal-organic framework compounds. Through the chosen synthetic approach, highly
dispersed Ni-based catalysts embedded in a carbon matrix were obtained, suitable
for the methanation of CO2. These catalysts are targeted to be highly stable against
hydrogen dropouts that can occur due to weather fluctuations during the production
of green hydrogen using water electrolysis. However, a detailed understanding
of the underlying chemical mechanisms and the associated electronic structures
of the catalyst systems is necessary to design such a system in a targeted manner.
Detailed analysis of the catalyst precursor by XAS showed that although a suitable
pre-catalyst can be prepared even under mildly reducing conditions, traces of
Ni(II) are still present under reducing conditions during thermal decomposition,
and a pure Nifcc structure was not achieved. Detailed XES analysis of the same
pre-catalysts, using a novel combination of HERFD-XANES, theoretical calculations,
and VtC-XES, provided clear evidence for the presence of the desired carbon matrix,
as well as traces of NiO in the pre-catalyst, which has a beneficial effect on
the subsequent activity in the final catalyst. Finally, by in-situ investigation,
the temperature range in which the active catalyst species is formed could be
narrowed down to 80 to 200 C. Furthermore, a clear correlation was proven between
the loss of a stabilizing carbon layer and decreased activity.

text: Macrocyclization reactions are still challenging due to competing oligomerization,
which requires the use of small substrate concentrations. Here, the cationic tungsten
imido and tungsten oxo alkylidene N-heterocyclic carbene complexes [[W(N-2,6-Cl2-C6H3)(CHCMe2Ph(OC6F5)(pivalonitrile)(IMes)+
B(ArF)4−] (W1) and [W(O)(CHCMe2Ph(OCMe(CF3)2)(IMes)(CH3CN)+ B(ArF)4−] (W2) (IMes=1,3-dimesitylimidazol-2-ylidene;
B(ArF)4−=tetrakis(3,5-bis(trifluoromethyl)phenyl borate) have been immobilized
inside the pores of ordered mesoporous silica (OMS) with pore diameters of 3.3
and 6.8 nm, respectively, using a pore-selective immobilization protocol. X-ray
absorption spectroscopy of W1@OMS showed that even though the catalyst structure
is contracted due to confinement by the mesopores, both the oxidation state and
structure of the catalyst stayed intact upon immobilization. Catalytic testing
with four differently sized α,ω-dienes revealed a dramatically increased macrocyclization
(MC) and Z-selectivity of the supported catalysts compared to the homogenous progenitors,
allowing high substrate concentrations of 25 mM. With the supported complexes,
a maximum increase in MC-selectivity from 27 to 81 % and in Z-selectivity from
17 to 34 % was achieved. In general, smaller mesopores exhibited a stronger confinement
effect. A comparison of the two supported tungsten-based catalysts showed that
W1@OMS possesses a higher MC-selectivity, while W2@OMS exhibits a higher Z-selectivity
which can be rationalized by the structures of the catalysts.

text: The Saharan desert ant Cataglyphis bombycina is densely covered with shiny
silver setae (hair-like structures). Their appearance was explained by geometric
optics and total internal reflection. The setae also increase the emissivity of
the ant, as they form an effective medium. This work provides additional data
on microstructural details of the setae that are used to simulate the scattering
of an individual seta to explain their influence on the optical properties. This
is achieved by characterization of their structure using light microscopy and
scanning/transmission electron microscopy. How the microstructural features influence
scattering is investigated wave-optically within the limits of finite-difference
time-domain simulations from the ultraviolet to the mid-infrared spectral range
to elucidate the optical effects beyond ray optics and effective medium theory.
The results show that Mie scattering plays an important role in protecting the
ant from solar radiation and could be relevant for its thermal tolerance.

text: AbstractAlthough iron is a dream candidate
to substitute noble metals in photoactive complexes, realization of emissive and
photoactive iron compounds is demanding due to the fast deactivation of their
charge-transfer states. Emissive iron compounds are scarce and dual emission has
not been observed before. Here we report the FeIII complex
[Fe(ImP)2][PF6] (HImP = 1,1′-(1,3-phenylene)bis(3-methyl-1-imidazol-2-ylidene)),
showing a Janus-type dual emission from ligand-to-metal charge transfer (LMCT)-
and metal-to-ligand charge transfer (MLCT)-dominated states. This behaviour is
achieved by a ligand design that combines four N-heterocyclic
carbenes with two cyclometalating aryl units. The low-lying π*
levels of the cyclometalating units lead to energetically accessible MLCT states
that cannot evolve into LMCT states. With a lifetime of 4.6 ns, the strongly reducing
and oxidizing MLCT-dominated state can initiate electron transfer reactions, which
could constitute a basis for future applications of iron in photoredox catalysis.

text: The production of hydrogen and the utilization of biomass for sustainable
concepts of energy conversion and storage require gas sensors that discriminate
between hydrogen (H2) and carbon monoxide (CO). Mesoporous copper–ceria (Cu–CeO2)
materials with large specific surface areas and uniform porosity are prepared
by nanocasting, and their textural properties are characterized by N2 physisorption,
powder XRD, scanning electron microscopy, transmission electron microscopy, and
energy-dispersive X-ray spectroscopy. The oxidation states of copper (Cu+, Cu2+)
and cerium (Ce3+, Ce4+) are investigated by XPS. The materials are used as resistive
gas sensors for H2 and CO. The sensors show a stronger response to CO than to
H2 and low cross-sensitivity to humidity. Copper turns out to be a necessary component;
copper-free ceria materials prepared by the same method show only poor sensing
performance. By measuring both gases (CO and H2) simultaneously, it is shown that
this behavior can be utilized for selective sensing of CO in the presence of H2.

text: Room temperature sodium-sulfur (RT Na-S) batteries are considered potential
candidates for stationary power storage applications due to their low cost, broad
active material availability and low toxicity. Challenges, such as high volume
expansion of the S-cathode upon discharge, low electronic conductivity of S as
active material and herewith limited rate capability as well as the shuttling
of polysulfides (PSs) as intermediates often impede the cycle stability and practical
application of Na-S batteries. Sulfurized poly(acrylonitrile) (SPAN) inherently
inhibits the shuttling of PSs and shows compatibility with carbonate-based electrolytes,
however, its exact redox mechanism remained unclear to date. Herein, we implement
a commercially available and simple electrolyte into the Na-SPAN cell chemistry
and demonstrate its high rate and cycle stability. Through the application of
in situ techniques utilizing electronic impedance spectroscopy (EIS) and X-ray
absorption spectroscopy (XAS) at different depths of charge and discharge, an
insight into SPAN’s redox chemistry is obtained.
