text: AbstractUnderstanding how water interacts
with nanopores of carbonaceous electrodes is crucial for energy storage and conversion
applications. A high surface area of carbonaceous materials does not necessarily
need to translate to a high electrolyte‐solid interface area. Herein, we study
the interaction of water with nanoporous C1N1
materials to explain their very low specific capacitance in aqueous electrolytes
despite their high surface area. Water was used to probe chemical environments,
provided by pores of different sizes, in 1H MAS NMR experiments.
We observe that regardless of their high hydrophilicity, only a negligible portion
of water can enter the nanopores of C1N1,
in contrast to a reference pure carbon material with a similar pore structure.
The common paradigm that water easily enters hydrophilic pores does not apply
to C1N1 nanopores below a few nanometers.
Calorimetric and sorption experiments demonstrated strong water adsorption on
the C1N1 surface, which restricts water
mobility across the interface and impedes its penetration into the nanopores.

text: The electrochemical properties of carbonaceous materials produced by hydrothermal
carbonization, referred to as hydrochar, can be substantially improved by post-carbonization
via pyrolysis. Although these materials have been widely studied for a variety
of applications, the mechanisms underlying the pyrolysis are yet poorly understood.
This study provides a comprehensive temperature-resolved characterization of the
chemical composition, morphology and crystallinity of sucrose-derived hydrochar
during pyrolysis. Thermogravimetric analysis, differential scanning calorimetry,
and elemental analysis have shown that the dry hydrochar loses about 41% of its
dry mass due to the exothermic disintegration of oxygen-containing groups until
the carbonization is completed at about 850 °C with a total carbon yield of 93%.
The carbonization and aromatization of the initially furanic and keto-aliphatic
structure were analyzed by 13C solid-state nuclear magnetic resonance spectroscopy,
X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy.
The transition from an amorphous to a nanocrystalline graphitic structure was
analyzed using X-ray diffraction and Raman spectroscopy. The pore formation mechanism
was examined by helium ion microscopy, transmission electron microscopy, and nitrogen
adsorption measurements. The results indicate the formation of oxygen-rich nanoclusters
up to 700 °C, which decompose up to 750 °C leaving behind equally sized pores,
resulting in a surface area of up to 480 m2/g.

text: Thermally stabilized and subsequently carbonized nanofibers are a promising
material for many technical applications in fields such as tissue engineering
or energy storage. They can be obtained from a variety of different polymer precursors
via electrospinning. While some methods have been tested for post-carbonization
doping of nanofibers with the desired ingredients, very little is known about
carbonization of blend nanofibers from two or more polymeric precursors. In this
paper, we report on the preparation, thermal treatment and resulting properties
of poly(acrylonitrile) (PAN)/poly(vinylidene fluoride) (PVDF) blend nanofibers
produced by wire-based electrospinning of binary polymer solutions. Using a wide
variety of spectroscopic, microscopic and thermal characterization methods, the
chemical and morphological transition during oxidative stabilization (280 °C)
and incipient carbonization (500 °C) was thoroughly investigated. Both PAN and
PVDF precursor polymers were detected and analyzed qualitatively and quantitatively
during all stages of thermal treatment. Compared to pure PAN nanofibers, the blend
nanofibers showed increased fiber diameters, strong reduction of undesired morphological
changes during oxidative stabilization and increased conductivity after carbonization.

text: The Haller relationship was applied to estimate the nematic order parameter
S from 1H NMR spectra of fully protonated liquid crystals aligned in the magnetic
field. The NMR line shapes were approximated as doublets of very broad peaks.
Both the temperature-dependent doublet Splitting and the full width at half maximum
of the whole spectra were used for Haller extrapolation. The order parameters
obtained with the proposed approach for 4-cyano-4'-pentylbiphenyl (5CB) and the
nematic mixture E7 were found to be in good agreement with previously reports.

text: The combined benefits of moisture-stable phosphonic acids and mesoporous
silica materials (SBA-15 and MCM-41) as large-surface-area solid supports offer
new opportunities for several applications, such as catalysis or drug delivery.
We present a comprehensive study of a straightforward synthesis method via direct
immobilization of several phosphonic acids and phosphoric acid esters on various
mesoporous silicas in a Dean–Stark apparatus with toluene as the solvent. Due
to the utilization of azeotropic distillation, there was no need to dry phosphonic
acids, phosphoric acid esters, solvents, or silicas prior to synthesis. In addition
to modeling phosphonic acids, immobilization of the important biomolecule adenosine
monophosphate (AMP) on the porous supports was also investigated. Due to the high
surface area of the mesoporous silicas, a possible catalytic application based
on immobilization of an organocatalyst for an asymmetric aldol reaction is discussed.

text: Gelled lyotropic liquid crystals can be formed by adding a gelator
to a mixture of surfactant and solvent. If the gel network and the liquid-crystalline
phase coexist without influencing each other, the self-assembly is called orthogonal.
In this study, the influence of the organogelator 12-hydroxyoctadecanoic acid
(12-HOA) on the lamellar and hexagonal liquid crystalline phases of the binary
system H2O–C12E7 (heptaethylene glycol monododecyl ether) is investigated. More
precisely, we added 12-HOA at mass fractions from 0.015 to 0.05 and studied the
resulting phase diagram of the system H2O–C12E7 by visual observation of birefringence
and by 2H NMR spectroscopy. In addition, the dynamic shear moduli of the samples
were measured in order to examine their gel character. The results show that 12-HOA
is partly acting as co-surfactant, manifested by the destabilization of the hexagonal
phase and the stabilization of the lamellar phase. The higher the total surfactant
concentration, the more 12-HOA is incorporated in the surfactant layer. Accordingly,
its gelation capacity is substantially reduced in the surfactant solution compared
to the system 12-HOA–n-decane, and large amounts of gelator are required for gels
to form, especially in the lamellar phase.

text: "Abstract\r\n Flow fields and
shear-induced structures in the lamellar (L\r\n α\r\n
\ ) phase of the system triethylene glycol mono n-decyl
ether (C10E3)/water were investigated
by NMR velocimetry, diffusometry, and \r\n 2\r\n
\ H NMR spectroscopy. The transformation from multilamellar
vesicles (MLVs) to aligned planar lamellae is accompanied by a transient gradient
shear banding. A high-shear-rate band of aligned lamellae forms next to the moving
inner wall of the cylindrical Couette shear cell while a low-shear-rate band of
the initial MLV structure remains close to the outer stationary wall. The band
of layers grows at the expense of the band of MLVs until the transformation is
completed. This process scales with the applied strain. Wall slip is a characteristic
of the MLV state, while aligned layers show no deviation from Newtonian flow.
The homogeneous nature of the opposite transformation from well aligned layers
to MLVs via an intermediate structure resembling undulated
multilamellar cylinders is confirmed. The strain dependence of this transformation
appears to be independent of temperature. The shear diagram, which represents
the shear-induced structures as a function of temperature and shear rate, contains
a transition region between stable layers and stable MLVs. The steady-state structures
in the transition region show a continuous change from layer-like at high temperature
to MLV-like at lower temperature. These structures are homogeneous on a length
scale above a few micrometers."
