text: Modern traffic control systems are key to cope with current and future traffic
challenges. In this paper information obtained from a microscopic traffic estimation
using various data sources is used to feed a new developed traffic control approach.
The presented method can control a traffic area with multiple traffic light systems
(TLS) reacting to individual road users and pedestrians. In contrast to widespread
green time extension techniques, this control selects the best phase sequence
by analyzing the current traffic state reconstructed in SUMO and its predicted
progress. To achieve this, the key aspect of the control strategy is to use Model
Predictive Control (MPC). In order to maintain realism for real world applications,
among other things, the traffic phase transitions are modelled in detail and integrated
within the prediction. For the efficiency, the approach incorporates a fuzzy logic
preselection of all phases reducing the computational effort. The evaluation itself
is able to be easily adjusted to focus on various objectives like low occupancies,
reducing waiting times and emissions, few number of phase transitions etc. determining
the best switching times for the selected phases. Exemplary traffic simulations
demonstrate the functionality of the MPC-based control and, in addition, some
aspects under development like the real-world communication network are also discussed.

text: Abstract Polymer-derived silicon carbonitride ceramic (SiCN) is used as an
electrode material to prepare cylindrical sodium/sodium ion cells for solid-state
NMR investigations. During galvanostatic cycling structural changes of the environment
of sodium/sodium ions are investigated by applying 23Na in-situ solid-state NMR.
Changes of the signals assigned to sodium metal, intercalated sodium cation and
sodium cation originating from the electrolyte are monitored as well as the occurrence
of an additional signal in the region of metallic sodium. The intensity of this
additional signal changes periodically with the cycling process indicating the
reversibility of structures formed and deformed during the galvanostatic cycling.
To identify interactions of sodium/sodium ions with the SiCN electrode materials,
the cycled SiCN material is studied by 23Na ex-situ MAS NMR at high spinning rates
of 20 and 50 kHz to obtain appropriate spectral resolution.

text: A novel, efficient approach for the functionalization of microcrystalline
cellulose (MCC) is presented. The as-obtained material allows the immobilization
of chiral dirhodium catalysts preserving their enantioselectivity in asymmetric
cyclopropanation reactions. As model, microcrystalline cellulose is modified with
a polyethylene glycol derived linker, and Rh-2(S-DOSP)(4) is grafted on the material
to produce a heterogeneous catalyst. SEM images at different stages of the immobilization
show an unchanging uniform morphology, providing constantly good separation characteristics.
The modification of the cellulose material with the polyethylene derived linker
and the immobilization process are monitored using DNP enhanced H-1 -{\textgreater}
C-13 CP MAS NMR, quantitative F-19 MAS NMR, TGA and ICP-OES analysis, confirming
the success of the immobilization as well as the stability of bonds between the
used linker molecule and the cellulose material. Finally, the evaluation of the
produced catalyst is demonstrated in the asymmetric cyclopropanation reaction
between styrene and methyl(E)-2-diazo-4-phenylbut-3-enoate showing excellent enantioselectivity
with an ee of nearly 90% over a wide temperature range as well as good recyclability
characteristics in four consecutive catalysis cycles.

text: Six cluster salts which consist of hexanuclear cluster anions [Nb6Cl12iX6a]2–
(X = Cl or Br) and protonated crown ether molecules (15-crown-5 (15cr5) and 12-crown-4
(12cr4)) or crown ether-stabilized oxonium cations as well as one compound consisting
of neutral cluster units, [Nb6Cl16(H2O)2]·4 dioxane, were synthesized in good
to high yields. The single-crystal X-ray structures of six of these compounds
were determined. The cation/anion ratios and the bond distances confirm in all
cases oxidized cluster cores with 14 cluster-based electrons. The cations of the
cluster salts are either sandwich-type dimers of the formula [(15cr5)H]22+ or
[(15cr5)(H3O)]22+ with the protons or oxonium ions embedded in between the crown
ether rings or monomeric units in the case of [(12cr4)H]+. 1H NMR investigations
show that the cluster salts are strong Brønsted acids. The fact that the cluster
core of [Nb6Cl16(H2O)2]·4 dioxane is oxidized but still carries water ligands
indicates that within the multi-step reaction sequence of the formation of the
cluster-supported acids, the oxidation step happens much faster than the ligand
exchange steps. Temperature-dependent 2H MAS NMR spectra of deuterium-exchanged
[(15cr5)H]2[Nb6Cl18]·2 CHCl3 are indicative of dynamic processes of the hydrogen-bonded
protons within the crown ether molecule. Six cluster salts which consist of hexanuclear
cluster anions [Nb6Cl12iX6a]2– (X = Cl or Br) and protonated crown ether molecules
(15-crown-5 (15cr5) and 12-crown-4 (12cr4)) or crown ether-stabilized oxonium
cations as well as one compound consisting of neutral cluster units, [Nb6Cl16(H2O)2]·4
dioxane, were synthesized in good to high yields. The single-crystal X-ray structures
of six of these compounds were determined. The cation/anion ratios and the bond
distances confirm in all cases oxidized cluster cores with 14 cluster-based electrons.
The cations of the cluster salts are either sandwich-type dimers of the formula
[(15cr5)H]22+ or [(15cr5)(H3O)]22+ with the protons or oxonium ions embedded in
between the crown ether rings or monomeric units in the case of [(12cr4)H]+. 1H
NMR investigations show that the cluster salts are strong Brønsted acids. The
fact that the cluster core of [Nb6Cl16(H2O)2]·4 dioxane is oxidized but still
carries water ligands indicates that within the multi-step reaction sequence of
the formation of the cluster-supported acids, the oxidation step happens much
faster than the ligand exchange steps. Temperature-dependent 2H MAS NMR spectra
of deuterium-exchanged [(15cr5)H]2[Nb6Cl18]·2 CHCl3 are indicative of dynamic
processes of the hydrogen-bonded protons within the crown ether molecule.

text: Abstract Herein we report the mechanochemical Friedel-Crafts alkylation of
1,3,5-triphenylbenzene (TPB) with two organochloride cross-linking agents, dichloromethane
(DCM) and chloroform (CHCl3), respectively. During a thorough milling parameter
evaluation, the DCM-linked polymers were found to be flexible and extremely sensitive
toward parameter changes, which even enables the synthesis of a polymer with a
SSABET of 1670 m2/g, on par with the solution-based reference. Contrary, CHCl3-linked
polymers are exhibiting a rigid structure, with a high porosity that is widely
unaffected by parameter changes. As a result, a polymer with a SSABET of 1280
m2/g could be generated in as little as 30 minutes, outperforming the reported
literature analogue in terms of synthesis time and SSABET. To underline the environmental
benefits of our fast and solvent-free synthesis approach, the green metrics are
discussed, revealing an enhancement of the mass intensity, mass productivity and
the E-factor, as well as of synthesis time and the work-up in comparison to the
classical synthesis. Therefore, the mechanochemical polymerization is presented
as a versatile tool, enabling the generation of highly porous polymers within
short reaction times, with a minimal use of chlorinated cross-linker and with
the possibility of a post polymerization modification.

text: Polyethylene glycol (PEG) is increasingly used as an alternative green chemical
solvent. New experimental measurements on density, viscosity, and self-diffusion
coefficient are presented for PEG200, PEG400, and several binary mixtures of tri-
and hexaethylene glycol covering a temperature range from 298.15 to 358.15 K.
Because PEGs are polydisperse, the exact compositions of PEG200 from six different
vendors are analytically determined and found to be comparable. Thus, only two
of the most differing PEG200 samples are further examined. The effects of water
as the most common impurity on densities, viscosities, and self-diffusion coefficients
are inspected as well as the results of the “dry” samples obtained by extrapolation
to zero water content. The obtained results are carefully compared to the available
literature data. The temperature dependence of these physical properties is investigated
and found to be linear for density, while viscosity and self-diffusion coefficients
follow the Arrhenius law. Attempts to calculate the properties of the binary mixtures
and PEG200 samples from the mole fraction weighted average of the physical properties
of the mixture components result in reasonable agreement. Agreement between calculated
and measured molar volumes is within measurement uncertainty. Agreement of calculated
and measured viscosities is mostly within a few percent but increases with decreasing
temperature (largest viscosities) reaching values of up to 15%. Similarly, calculated
and measured self-diffusion coefficients mostly agree within 20%, which is near
the measurement uncertainty, but overestimates increase to 30% for the highest
temperatures (largest self-diffusion coefficients).

text: In this work, the behavior of four different commercially available polarizing
agents is investigated employing the non-ionic model surfactant 1-octanol as analyte.
A relative method for the comparison of the proportion of the direct and indirect
polarization transfer pathways is established, allowing a direct comparison of
the polarization efficacy for different radicals and different parts of the 1-octanol
molecule despite differences in radical concentration or sample amount. With this
approach, it could be demonstrated that the hydrophilicity is a key factor in
the way polarization is transferred from the polarizing agent to the analyte.
These findings are confirmed by the determination of buildup times Tb, illustrating
that the choice of polarizing agent plays an essential role in ensuring an optimal
polarization transfer and therefore the maximum amount of enhancement possible
for DNP enhanced NMR measurements.

text: Abstract The donor properties of a set of bulky ferrocene based bisphosphanes
(Fe(C5H4PMes2)2 and (C5H4PMes2)Fe(C5H4PtBu2 with Mes= mesityl and tBu=tert-butyl)
were probed by exploring the NMR parameters of the corresponding selenophosphoranes
amended by cyclovoltammetry. The ligand properties were explored in the complexation
of copper phenylacetylide which is relevant as intermediate in the Cu(I) catalyzed
CO2 addition to phenylacetylene. Owing to the poor solubility of the resulting
complexes their characterization was performed with solid state NMR spectroscopy
amended by IR spectroscopy, mass spectrometry and elemental analysis. Remarkably,
these complexes feature luminescent properties, albeit with limited quantum yield.

text: A lithium halide exchange reaction at low-temperature, via the treatment of
2,6-di(isopropyl)phenyllithium on 1,1′-bis-(dichlorophosphino)ferrocene, resulted
in the first isolated example of an aryl-substituted diphospha [2]ferrocenophane
(diphospha [2]FCP) 2. Although compound 2 did not show any recognizable thermal
reaction at higher temperature (up to 350 °C), its tert-butyl-substituted counterpart
1 underwent a clean selective heat-mediated P–C cleavage reaction, followed
by an inter-molecular rearrangement, to produce a P–P fused bis [3]ferrocenophane
3 with all-trans oriented P-chain, which upon further heating gave a polyferrocenylphosphane
tBu-[Fc’P2]n-tBu (4). Since polymer 4 is insoluble in common organic solvents,
it has been characterized with solid-state techniques, including solid-state NMR.
Density functional theory (DFT) has further been employed to identify possible
pathways for P–C bond cleavage on 1 and 2, as well as to evaluate accessible
pathways for further polymerization toward 4.
