text: 'This study presents an appealing approach to sustainable catalysis using
cellulose filter paper as a support for copper-catalyzed reactions. The paper
was functionalized with thiol groups through a reaction with thioglycolic acid,
which served a dual purpose: partially reducing Cu(II) to Cu(I) and stabilizing
active copper species via Cu–S interactions. Spectroscopic analysis confirmed
the formation of highly dispersed multi-valent Cu2O/CuO on the thiol-functionalized
cellulose, resulting in a highly efficient copper catalyst. This catalyst demonstrated
excellent performance in the oxidative coupling of various amines to imines, achieving
yields of 39–99% within 10–30 min. A key advantage of this system is its reusability;
the catalyst maintained remarkable stability and activity over ten reaction cycles
with straightforward recovery. This paper-based catalyst offers a promising strategy
for eco-friendly and cost-effective synthetic processes, with significant implications
for green chemistry and industrial applications.'

materials and provide a versatile design strategy for porous macroligands. Based
on the prototypical triphenylphosphine (PPh3) monomer, we investigate the role
of the involved cross-linking reagents in the formation of polyphosphines and
evaluate structure–activity relations for application in the catalytic CO2 hydrogenation:
namely by varying the Friedel–Crafts catalyst, the cross-linker unit and the degree
of cross-linking. The study of monomeric reactivities shows that phosphines are
insufficiently activated by iron chloride catalyzed cross-linking and that the
stronger aluminum chloride is required to ensure PPh3 incorporation. Applying
aromatic cross-linker units introduces porosity and promotes the accessibility
of ligating centers for the immobilized ruthenium species. The thus formed solid
catalysts exhibit excellent performances in the hydrogenation of CO2 to formic
acid in the aqueous phase and are studied in successive recycling runs. The partial
structural degradation of the frameworks during catalysis is addressed by adjusting
higher degrees of cross-linking, leading to an improved stabilization of the catalyst.

text: The understanding of the interactions between cellulose and ionic liquids
are the foundation for the development of new processes, to explore new reactions
and to establish a circular bioeconomy. The main problem is that direct measurement,
from both quantitative and qualitative point of view is challenging. While there
are methods to assess solution strength and wettability of ionic liquids with
cellulose materials, the main challenge lies in the combination of a solid substrate
and an applied liquid, limiting the number of accessible methods. We demonstrate
in this paper that an in-situ solid-state NMR spectroscopical approach is capable
of monitoring in real-time the mobility of ionic liquids in cellulose-based substrates.
Specifically, we employ 1H → 13C cross polarization magic angle spinning (CP MAS)
NMR spectroscopy to examine mobility changes over varying exposure times in paper
samples treated with ionic liquids. Through this approach, we capture the temporal
evolution of IL signals, which in turn provide insights into mobility changes
of ILs and also allow for identifying changes in cellulose crystallinity. The
approach allows for a simple, semiquantitative assessment of cellulose solubility
in ionic liquids and is in principle applicable to other biomass materials as
well.

text: Herein, we report a solid-state polycyclotrimerization of 1,4-diethynylbenzene
using mechanochemical activation in a ball mill, yielding a highly porous and
hydrophobic hyperbranched polymer (HBP) with a specific surface area of up to
570 m2 g−1. The reaction, catalyzed by Fe(hmds)2 and conducted under solvent-free
conditions, was optimized by varying milling time and frequency. This method enables
the efficient synthesis of insoluble, porous organic polymers with high yields
(up to 95%) and offers an environmentally friendly alternative to traditional
solution-based polymerizations.

text: The thermal behavior of n-octanol and related ether alcohols has been studied
by differential scanning calorimetry (DSC). The melting point, heat of fusion,
and isobaric heat capacities of n-octanol obtained from the DSC measurements are
in good agreement with literature values. The ether alcohols display kinetic barriers
for forming a solid phase during cooldown. These barriers are least for 6-methoxyhexanol
that forms a solid upon cooling except for the highest measured temperature change
rate of 40 K·min–1, followed by 4-propoxybutanol that forms a solid during cooldown
only at low cooling rates. 2-Pentoxyethanol and 5-ethoxypentanol form a solid
during the heating cycle that then melts again upon further heating. 3-Butoxypropanol
does not display any exo- and endothermic features for all measured temperature
change rates. Consequently, new data on melting point and heats of fusion are
reported for the ether alcohols except for 3-butoxypropanol. New isobaric heat
capacities are presented as well for the liquid phase of these ether alcohols.

text: Sodium-ion batteries are at the forefront of new, sustainable energy systems
required for the global energy transition. 23Na in situ solid-state nuclear magnetic
resonance spectroscopy is capable of unraveling structures in working electrochemical
cells during the charging and discharging processes. To evaluate its suitability
for long-term studies, local sodium environments in sodium/sodium ion cells based
on silicon carbonitride and hard carbon materials are tracked for up to 49 cycles
(228.5?h). The formation of dendrites as well as the decay of a secondary metallic
sodium species is observed, and local structures are analyzed up to the point
of capacity degradation and cell failure. Initial points of cell breakdown are
reflected in the NMR data by characteristic changes in signal intensities, whereas
the degradation of the cells is reflected by a cease to periodic signal intensity
fluctuations. Meanwhile, ex situ 23Na NMR spectra of the deactivated cells reveal
a complex range of environments for sodium ions.

text: para-Hydrogen induced polarisation (PHIP) is an excellent tool for extracting
mechanistic information in catalysis since it circumvents the intrinsic low sensitivity
of nuclear magnetic resonance (NMR) spectroscopy. We report a class of iron complexes
that are highly active in olefin hydrogenation catalysis and act as PHIP catalysts
at 1.4 Tesla. Moreover, hyperpolarisation transfer to 19F is observed.

text: Redox flow batteries (RFBs) are promising solutions for large-scale stationary
energy storage due to their scalability and long cycle life. The efficient operation
of RFBs requires a thorough understanding of the complex electrochemical processes
occurring during charging and discharging. This review provides an overview and
perspective of in situ and in operando analytical techniques to monitor RFBs.
In more detail, these advanced techniques allow for real-time observation of redox
reactions, ion transport, and electrode–electrolyte interactions under working
conditions, offering insights into formation of intermediate species and mechanisms
of electrolyte degradation, State-of-Charge (SoC), and ion crossover. By discussing
the principles, capabilities, and limitations of techniques such as nuclear magnetic
resonance (NMR), electron paramagnetic resonance (EPR), ultraviolet-visible (UV-vis)
spectroscopy, Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR),
X-ray absorption spectroscopy (XAS), electrochemical impedance spectroscopy (EIS),
tomography and radiography, mass spectrometry (MS), and fluorescence microscopy
this review highlights the essential role of in situ and in operando approaches
in advancing RFB technology.

text: Sodium batteries are an attractive alternative for future energy storage as
they can be produced with abundant and low-cost materials. Nonetheless, sodium-ion
batteries (SIBs) are often composed of flammable and volatile carbonate-based
liquid electrolytes. Polymer electrolytes have attracted significant attention
as safer alternatives. Among polymer electrolytes, single-ion conductive polymer
electrolytes (SIPEs) are considered particularly interesting because they can
suppress dendrite growth, enabling high-performance (quasi)-solid-state sodium–(metal)
batteries. In this work, a self-standing, flexible, quasi-solid-state SIPE is
investigated, which is composed of sodium 4-styrene sulfonyl (trifluoromethanesulfonyl)
imide (NaSTFSI), pentaerythritol tetrakis(3-mercaptopropionate) (PETMP) and pentaerythritol
tetraacrylate (PET4A) blended with poly(vinylidene fluoride-co-hexafluoropropylene)
(PVDF-HFP). The SIPE membrane, including 50 wt% of molecular transporter, exhibits
ionic conductivity of 1.4 × 10−5 S cm−1 and 1.3 × 10−4 S cm−1 at 20 °C and 90
°C, respectively, thermal stability up to 280 °C, electrochemical stability window
up to 4.5 V vs. Na/Na+, and Na plating/stripping reversibility in symmetric Na‖Na
cells. The manufactured SIPE implemented in Prussian White (PW)‖Na cells enables
the delivery of 147 mA h g−1 of PW at 15 mA g−1 with a Coulombic efficiency of
over 99%, which is comparable with the PW‖Na cells using liquid carbonate electrolyte,
confirming the suitability of the designed SIPE for sodium–(metal) batteries.

text: Abstract Novel SBA-15-supported heterogeneous catalysts are synthesized and
applied in the Mizoroki?Heck and the Suzuki?Miyaura cross-coupling reactions in
green solvents like PEG or water. The structural properties of the products after
each synthesis step are monitored by different analytics. The amount of amine/carboxyl
groups and vanillin/histidine methyl ester and thermal stability are determined
by TGA and elemental analysis, while ICP-OES delivered the amount of palladium
of the catalysts. The morphology is investigated by SEM and XPS and confirms the
presence of coordinated palladium in the zero-oxidation state. Gas adsorption
analysis is conducted, which indicates the presence of palladium clusters in one
of the two catalysts, which is underlined by BSE images combined with EDX. A detailed
13C ssNMR and DNP-enhanced 15N ssNMR spectral analysis is presented, which provides
ultimate proof of the successful syntheses of the catalysts. The coordination
of the palladium onto the carrier material is shown by combining the NMR spectral
results with the results of the other analytics. First catalytic tests show for
the Mizoroki?Heck reaction yields up to nearly 100% and for the Suzuki-Miyaura
up to 88% in the presence of PEG and water, respectively.

text: In this study, electrochemical processes in a Li{\textbar}LiPF6{\textbar}LFP
cell have been explored applying advanced solid-state NMR technologies. In situ
solid-state NMR allows to monitor structural changes in local environments in
commercially available cell components during galvanostatic cycling. In collaboration
with Dragonfly Energy, ePROBE GmbH and Bruker BioSpin GmbH & Co. KG, we have demonstrated
an experimental procedure for routine application of in situ solid-state NMR for
battery research. This points out the high potential of this approach for use
in the energy storage industry.

text: Abstract Donor stabilization of Sn(II) and Pb(II) halides with 1,1?-ferrocenylene
bridged bisphosphanes has been explored for Fe(C5H4P(C6H5)2)2 (dppf), and Fe(C5H4PH(C4H9))2.
These bisphosphanes are reacted with SnBr2 and PbCl2 with and without additional
Lewis acid (AlCl3) forming acyclic and cyclic donor adducts from which the latter
represent bisphosphoniotetrylenes. Since dynamic exchange in solution is observed,
characterization includes solution and solid-state NMR in addition to SC-XRD,
amended by DFT calculations.

text: Porous organic polymers enable a novel approach to incorporate xantphos into
a solid macroligand. Immobilizing a ruthenium complex on the xantphos framework
results in an excellent catalyst for the hydrogenation of CO2 to formic acid.
Recycling experiments indicate a minor partial degradation of the heterogenous
catalyst after a certain induction period, which is referred to its structural
changes.

text: The production of formaldehyde on industrial scale requires huge amounts of
energy due to the involvement of reforming processes in combination with the demand
in the megaton scale. Hence, a direct route for the transformation of (bio)methane
to formaldehyde would decrease costs and puts less pressure on the environment.
Herein, we report on the use of zinc modified silicas as possible support materials
for vanadium catalysts and the resulting consequences for the performance in the
selective oxidation of methane to formaldehyde. After optimization of the Zn content
and reaction conditions, a remarkably high space-time yield of 12.4 kgCH2O·kgcat−1·h−1
was achieved. As a result of the extensive characterization by means of UV–vis,
Raman, XANES and NMR spectroscopy it was found that vanadium is in the vicinity
of highly dispersed zinc atoms which promote the formation of active vanadium
species as supposed by theoretical calculations. This work presents a further
step of catalyst development towards direct industrial methane conversion which
may help to overcome current limitations in the future.

text: We introduce the first mechanochemical cyclotrimerization of nitriles, a facile
strategy for synthesizing triazine-containing molecules and materials, overcoming
challenges related to carbonization and solubility. Conducting this solid-state
approach in a mixer ball mill with 4-Methylbenzonitrile, we synthesize Tris(4-methylphenyl)-1,3,5-triazine
quantitatively in as little as 90 minutes. Just as fast, this mechanochemical
method facilitates the synthesis of the covalent triazine framework CTF-1 using
1,4 Dicyanobenzene. Material characterization confirms its porous (650 m2 g-1)
and crystalline nature. Adjusting the induced mechanical energy allows control
over the obtained stacking conformation of the resulting CTFs - from a staggered
AB arrangement to an eclipsed AA stacking conformation. Finally, a substrate scope
demonstrates the versatility of this approach, successfully yielding various CTFs.
This work presents, for the first time, the mechanochemical cyclotrimerization
of nitriles. Utilizing Trifluoromethanesulfonic acid and a ball mill, both small
molecules and large organic frameworks could be obtained. Screening the reaction
of 1,4-Dicyanobenzene by various parameters, such as reaction time, frequency,
or temperature, significant impacts on the porosity of the polymer and its crystallinity
were revealed. image

text: Density, viscosity, and self-diffusion coefficients are reported for octan-1-ol
and the related ether-alcohols 2-pentoxy-ethan-1-ol, 3-butoxypropan-1-ol, 4-propoxybutan-1-ol,
5-ethoxypentan-1-ol, and 6-methoxyhexan-1-ol covering temperature ranges from
298.15 to 359.15 K. These new data reveal structure–property relationships affected
by the presence and the position of the ether moiety in the molecular structure
of the ether-alcohols. Compared to octan-1-ol, the presence of the ether moiety
causes an increase in intermolecular hydrogen bonding interactions, resulting
in higher densities. The increase in density is less pronounced for those ether-octanols
that engage in intramolecular hydrogen bonding. As for the effects of the ether
moiety on the dynamics, these are generally faster for the ether-alcohols compared
to octan-1-ol, suggesting that hydrogen bonding between ether oxygen and hydroxy
hydrogen is weaker compared to hydrogen bonding between two hydroxy groups. The
activation energies obtained from an Arrhenius analysis are higher for translational
motion than for momentum transfer for all alcohols. There are additional finer
details across the ether alcohols for these activation barriers. These differences
cancel out for the mathematical product of self-diffusion coefficient and viscosity
(Dη). The effect of water impurities on the studied properties was also investigated
and found to lead to small increases in densities for all alcohols. Viscosities
decrease for octan-1-ol and 2-pentoxyethan-1-ol but increase for the other ether-alcohols
that can engage in intramolecular hydrogen bonding. Density, viscosity, and self-diffusion
coefficients are reported for octan-1-ol and the related ether-alcohols 2-pentoxy-ethan-1-ol,

text: This concept summarizes recent advances in development and application of
DNP enhanced multinuclear solid-state NMR to study the molecular structure and
surface functionalization of cellulose and paper-based materials. Moreover, a
novel application is presented where DNP enhanced 13C and 15N solid-state NMR
is used to identify structure moieties formed by cross-linking of hydroxypropyl
cellulose. Given these two aspects of this concept-type of article, we thus combine
both, a review on recent findings already published and unpublished recent data
that complement the existing knowledge in the field of characterization of functional
lignocellulosic materials by DNP enhanced solid-state NMR.
