text: Periodate oxidation reaction occurring directly on chitin has been neglected
in polysaccharide chemistry so far. Herein, we present the first direct alkaline
periodate oxidation of chitin, which demonstrates at the same time a novel approach
for the preparation of chitin nanocrystals (ChNCs). This oxidation is based on
an unprecedented selective reaction of non-ordered domains of chitin by the dimeric
orthoperiodate ions (H2I2O104−) as the major species in alkaline surroundings.
Nearly 50 wt% of non-ordered regions are dissolved after sequential accelerated
partial deacetylation, periodate oxidation and β-alkoxy fragmentation, which allows
the isolation of up to 50 wt% of uniform anisotropic zwitterionic ChNCs.

text: Three chiral dirhodium coordination polymers Rh2–Ln (n = 1–3) have been synthesized
via ligand exchange between dirhodium trifluoroacetate Rh2(TFA)4 and differently
sized chiral dicarboxylic acids derived from l-tert-leucine. SEM images indicate
that the Rh2–Ln (n = 1–3) polymers have a lamellar structure. XPS data demonstrate
that the oxidation state of rhodium in the dirhodium nodes is maintained during
the synthesis of the polymers. The coordination polymers have been further characterized
by FTIR, 1H → 13C CP MAS NMR and 19F MAS NMR spectroscopy to prove the formation
of polymers via ligand exchange. Although the quantitative 19F MAS NMR spectra
reveal incomplete ligand substitution in the coordination polymers, these catalysts
show excellent activity and selectivity in the asymmetric cyclopropanation reaction
between styrene and diazooxindole. In particular, the enantioselectivity has been
significantly improved compared with previously designed dirhodium coordination
polymers, which were synthesized from aromatic dicarboxylic acids derived from
l-phenylalanine. Meanwhile, the dirhodium polymers can be easily recycled five
times without significant reduction in their catalytic efficiency.

text: A novel immobilized chiral dirhodium catalyst, Rh2(S-PTTL)3(S-PTTL-linker)∼SBA-15
(8), has been prepared via click reaction of azide-groups on functionalized SBA-15
with the dirhodium complex Rh2(S-PTTL)3(S-PTTL-alkyne) (6) containing an alkyne
moiety. During the synthesis of this complex, one chiral ligand of the parent
Rh2(S-PTTL)4 catalyst is exchanged with an analogous chiral ligand system containing
an alkyne moiety, which to a great extent maintains the intrinsic catalytic performance
of the catalyst. The heterogeneous dirhodium catalyst is characterized by FT-IR
and 13C solid-state NMR to validate the successful immobilization. The catalytic
performance of the heterogeneous catalyst 8 is investigated in the asymmetric
cyclopropanation of 3-diazooxindole with different aryl alkenes that form spiro-cyclopropyloxindoles
which serve as precursors for pharmaceuticals. The resulting heterogeneous catalyst
shows high catalytic activity and significant enantioselectivity. Importantly,
it can be readily recovered and reused at least four times without significant
loss of its catalytic performance.

text: A synthetic strategy to β-silylphospholes with three methoxy, ethoxy, chloro,
hydrido, or phenyl substituents at silicon has been developed, starting from trimethoxy,
triethoxy, or triphenyl silyl substituted phenyl phosphanides and 1,4-diphenyl-1,3-butadiyne.
These trifunctional silylphospholes were attached to the surface of uniform spheric
silica particles (15 μm) and, for comparison, to a polyhedral silsesquioxane (POSS)–trisilanol
as a molecular model to explore their luminescent properties in comparison with
the free phospholes. Density functional theory calculations were performed to
investigate any electronic perturbation of the phosphole system by the trifunctional
silyl anchoring unit. For the immobilized phospholes, cross-polarization magic-angle-spinning
NMR measurements (13C, 29Si, and 31P) were carried out to explore the bonding
situation to the silica surface. Thermogravimetric analysis and X-ray photoelectron
spectroscopy measurements were performed to approximate the amount of phospholes
covering the silica surface. Identity and purity of all novel phospholes have
been established with standard techniques (multinuclear NMR, mass spectrometry,
and elemental analysis) and X-ray diffraction for the POSS derivative.

text: Solid-state NMR combined with dynamic nuclear polarization (DNP NMR) is used
to study hydration processes in tricalcium silicate (Ca3SiO5, abbreviated as C3S)
samples. The studied C3S samples have experienced early stage hydration (1–30
h) and slow aging (9 years) processes. The appearance of Q3 and Q4 lines in the
29Si MAS and 1H → 29Si CP MAS NMR spectra obtained for partly hydrated C3S samples
indicated the formation of amorphous silica which corresponds to their carbonation,
which was corroborated by complementary FTIR data. Significant DNP signal enhancements
obtained for the studied samples allowed to further investigate the C3S carbonation
process in detail employing the 1H → 29Si CP MAS FSLG HETCOR technique. Finally,
DNP enhanced 1H → 13C CP MAS and 1H → 13C CP MAS FSLG HETCOR techniques enabled
to directly observe the formation of carbonate moieties in partly hydrated C3S
samples.

text: Polyethylene glycol (PEG) is gaining interest as an alternative green solvent
in chemical synthesis and processing. This report presents density and viscosity
data from 293.15 K to 358.15 K as well as self-diffusion coefficient data from
298.15 K to 358.15 K for oligomers of PEG from di- to nonaethylene glycol. The
results were obtained by extrapolation from measurement series where water, the
most common impurity in PEGs, was intentionally added in several increments. The
obtained results are carefully compared to literature data, which are widely available
only for density and viscosity, and only for the lower oligomers. Densities are
found to be linearly dependent on temperatures for all studied oligomers. The
temperature dependence of viscosity and self-diffusion coefficients show only
slight deviations from the Arrhenius equation over the investigated temperature
range. The activation energies obtained from the viscosity data agree well with
the activation energies from the self-diffusion coefficient data and appear to
be linearly dependent with respect to the number of ethylene oxide repeat units
in the PEG oligomer. This linearity combined with the observation that the pre-exponential
factor appears to be the same for all studied oligomers may serve as a tool to
estimate viscosities and self-diffusion coefficients for higher oligomers within
the investigated temperature range. The densities of the oligomers all fall within
a rather narrow range without a clear trend in homologous series.

text: 13C and 15N solid-state nuclear magnetic resonance (NMR) combined with dynamic
nuclear polarization (DNP) is used to investigate the structure of dye-doped biopolymer-based
materials that can be used in amplified spontaneous emission (ASE) experiments.
By comparing calligraphic paper prepared from cellulose and scaffolds prepared
from chitosan as substrates, differences in the interactions of the carrier material
with the dye molecule Calcofluor White are obtained. These are most probably induced
by structural changes of the carrier material due to its interaction with water
forming hydrogen bonds. Such structural differences may explain the obtained variation
of the emission wavelength of Calcofluor White doped on these substrates in ASE
experiments.

text: A novel specific spin-labeling strategy for bioactive molecules is presented
for eptifibatide (integrilin) an antiplatelet aggregation inhibitor, which derives
from the venom of certain rattlesnakes. By specifically labeling the disulfide
bridge this molecule becomes accessible for analytical techniques such as Electron
Paramagnetic Resonance (EPR) and solid state Dynamic Nuclear Polarization (DNP).
The necessary spin-label was synthesized and inserted into the disulfide bridge
of eptifibatide via reductive followed by insertion by a double Michael addition
under physiological conditions. This procedure is universally applicable for disulfide
containing biomolecules and is expected to preserve their tertiary structure with
minimal change due to the small size of the label and restoring of the previous
disulfide connection. HPLC and MS analysis show the successful introduction of
the spin label and EPR spectroscopy confirms its activity. DNP-enhanced solid
state NMR experiments show signal enhancement factors of up to 19 in 13C CP MAS
experiments which corresponds to time saving factors of up to 361. This clearly
shows the high potential of our new spin labeling strategy for the introduction
of site selective radical spin labels into biomolecules and biosolids without
compromising its conformational integrity for structural investigations employing
solid-state DNP or advanced EPR techniques.

text: The interactions of molecules such as surfactants with solid interfaces are
not sufficiently understood since their study is challenging with standard spectroscopic
methods. In this work, octanol-d17 as a model system confined in the mesopores
of SBA-15 is studied by variable temperature deuterium solid-state NMR, and the
findings are compared to those of bulk octanol-d17. The magic angle spinning (MAS)
as well as the static, nonspinning case, are investigated, showing that the described
observations are independent of the applied NMR method. The 2H NMR spectra of
both the bulk and the confined octanol-d17 show a large and a small quadrupolar
Pake pattern below the melting point, suggesting a rigid conformation of the observed
molecules with a 3-fold jump motion of the terminal CD3-group. Apart from the
melting of the solid, no other phase transition is observed for either sample.
The confined octanol-d17 forms a pore solid, exhibiting a melting point 38 K lower
than bulk octanol-d17. The interactions of the molecule with the mesoporous SBA-15
bring about a distribution of activation energies for the melting process, resulting
in a gradual melting process.

text: "When engaging in argumentative discourse, skilled human debaters tailor\r\nclaims
to the beliefs of the audience, to construct effective arguments.\r\nRecently,
the field of computational argumentation witnessed extensive effort\r\nto address
the automatic generation of arguments. However, existing approaches\r\ndo not
perform any audience-specific adaptation. In this work, we aim to bridge\r\nthis
gap by studying the task of belief-based claim generation: Given a\r\ncontroversial
topic and a set of beliefs, generate an argumentative claim\r\ntailored to the
beliefs. To tackle this task, we model the people's prior\r\nbeliefs through their
stances on controversial topics and extend\r\nstate-of-the-art text generation
models to generate claims conditioned on the\r\nbeliefs. Our automatic evaluation
confirms the ability of our approach to adapt\r\nclaims to a set of given beliefs.
In a manual study, we additionally evaluate\r\nthe generated claims in terms of
informativeness and their likelihood to be\r\nuttered by someone with a respective
belief. Our results reveal the limitations\r\nof modeling users' beliefs based
on their stances, but demonstrate the\r\npotential of encoding beliefs into argumentative
texts, laying the ground for\r\nfuture exploration of audience reach."
