text: Proton exchange membranes (PEMs) are essential for fuel cells, yet conventional
materials like Nafion suffer from humidity dependence and limited thermal stability.
This study introduces sulfonated phenylene-bridged periodic mesoporous organosilicas
(PMOs) as promising inorganic–organic hybrid PEMs, synthesized via surfactant-templating
with varying alkyl chain lengths for different mesopore sizes. Post-synthetic
functionalization involves nitration of phenylene moieties, reduction to amines,
and ring-opening of propane or butane sultones to graft sulfonic acid groups via
flexible spacers, achieving homogeneous distribution along pore walls. Post-functionalization
is confirmed by powder X-ray diffraction (PXRD), revealing preserved 2D hexagonal
p6mm ordering and phenylene stacking. N2 physisorption shows type IV isotherms
with reduced pore volumes and pore sizes. 1H NMR is used to quantify functionalization
degrees. Impedance spectroscopy on pressed pellets demonstrates proton conductivities
up to 2 × 10−3 S cm−1 at 30 °C and 90% RH, depending on the functionalization
degree, confirming sulfonic acid-mediated conduction.

text: The presence of a polymer network and/or the addition of ferroelectric
nanoparticles to a nematic liquid crystal are found to lower transition temperatures
and birefringence, which indicates reduced orientational order. In addition, the
electro-optic switching voltage is considerably increased when a polymer network
is formed by in situ polymerization in the nematic state. However, the resulting
polymer network liquid crystal switches at similar voltages as the neat liquid
crystal when polymerization is performed at an elevated temperature in the isotropic
state. When nanoparticle dispersions are polymerized at an applied DC voltage,
the transition temperatures and switching voltages are reduced, yet they are larger
than those observed for polymer network liquid crystals without nanoparticles
polymerized in the isotropic phase.

text: Pore engineering is commonly used to alter the properties of metal–organic
frameworks. This is achieved by incorporating different linker molecules (L) into
the structure, generating isoreticular frameworks. CPO-27, also named MOF-74,
is a prototypical material for this approach, offering the potential to modify
the size of its one-dimensional pore channels and the hydrophobicity of pore walls
using various linker ligands during synthesis. Thermal activation of these materials
yields accessible open metal sites (i.e., under-coordinated metal centers) at
the pore walls, thus acting as strong primary binding sites for guest molecules,
including water. We study the effect of the pore size and linker hydrophobicity
within a series of Ni2+-based isoreticular frameworks (i.e., Ni2L, L = dhtp, dhip,
dondc, bpp, bpm, tpp), analyzing their water sorption behavior and the water interactions
in the confined pore space. For this purpose, we apply water vapor sorption analysis
and Fourier transform infrared spectroscopy. In addition, defect degrees of all
compounds are determined by thermogravimetric analysis and solution 1H nuclear
magnetic resonance spectroscopy. We find that larger defect degrees affect the
preferential sorption sites in Ni2dhtp, while no such indication is found for
the other materials in our study. Instead, strong evidence is found for the formation
of water bridges/chains between coordinating water molecules, as previously observed
for hydrophobic porous carbons and mesoporous silica. This suggests similar sorption
energies for additional water molecules in materials with larger pore sizes after
saturation of the primary binding sites, resulting in more bulk-like water arrangements.
Consequently, the sorption mechanism is driven by classical pore condensation
through H-bonding anchor sites instead of sorption at discrete sites.

text: 'Site-controlled Ga droplets on AlGaAs substrates are fabricated using
area-selective deposition of Ga through apertures in a mask during molecular beam
epitaxy (MBE). The Ga droplets can be crystallized into GaAs quantum dots using
a crystallization step under As flux. In order to model the complex process, including
the masked deposition of the droplets and a reduction of their number during a
thermal annealing step, a multiscale kinetic Monte Carlo (mkMC) simulation of
self-assembled Ga droplet formation on AlGaAs is expanded for area-selective deposition.
The simulation has only two free model parameters: the activation energy for surface
diffusion and the activation energy for thermal escape of adatoms from a droplet.
Simulated droplet numbers within the opening of the aperture agree quantitatively
with the experimental results down to the perfect site-control, with one droplet
per aperture. However, the model parameters are different compared to those of
the self-assembled droplet growth. We attribute this to the presence of the mask
in close proximity to the surface, which modifies the local process temperature
and the As background. This approach also explains the dependence of the model
parameters on the size of the aperture.'

text: In this work, the electrografting of Al-7075 aluminium alloy substrates
with 4-nitrobenzenediazonium salt (4-NBD) films was studied on a complex aluminium
alloy surface. Prior to the electrografting reaction, the substrates were submitted
to different surface treatments to modify the native aluminium oxide layer and
unveil intermetallic particles (IMPs). The formation of the 4-NBD films could
be correlated with the passive film state and the distribution of IMPs. The corresponding
electrografting reaction was performed by cyclic voltammetry which allowed the
simultaneous analysis of the redox reaction by a number of complementary surface-analytical
techniques. Spatially resolved thin film analysis was performed by means of SEM-EDX,
AFM, PM-IRRAS, Raman spectroscopy, XPS, and SKPFM. The collected data show that
the 4-NBD film is preferentially formed either on the Al oxide layer or the IMP
surface depending on the applied potential range. Potentials between −0.1 and
−1.0 VAg/AgCl mostly generated nitrophenylene films on the oxide covered aluminium,
while grafting between −0.1 and −0.4 VAg/AgCl favours the growth of these films
on IMPs.

text: 'Zinc oxide nanoparticles (ZnO NP) used for the channel region in
inverted coplanar setup in Thin Film Transistors (TFT) were the focus of this
study. The regions between the source electrode and the ZnO NP and the drain electrode
were under investigation as they produce a Schottky barrier in metal-semiconductor
interfaces. A more general Thermionic emission theory must be evaluated: one that
considers both metal/semiconductor interfaces (MSM structures). Aluminum, gold,
and nickel were used as metallization layers for source and drain electrodes.
An organic-inorganic nanocomposite was used as a gate dielectric. The TFTs transfer
and output characteristics curves were extracted, and a numerical computational
program was used for fitting the data; hence information about Schottky Barrier
Height (SBH) and ideality factors for each TFT could be estimated. The nickel
metallization appears with the lowest SBH among the metals investigated. For this
metal and for higher drain-to-source voltages, the SBH tended to converge to some
value around 0.3 eV. The developed fitting method showed good fitting accuracy
even when the metallization produced different SBH in each metal-semiconductor
interface, as was the case for gold metallization. The Schottky effect is also
present and was studied when the drain-to-source voltages and/or the gate voltage
were increased.'

text: Block copolymer (BCP) self-assembly is a promising tool for next generation
lithography as microphase separated polymer domains in thin films can act as templates
for surface nanopatterning with sub-20 nm features. The replicated patterns can,
however, only be as precise as their templates. Thus, the investigation of the
morphology of polymer domains is of great importance. Commonly used analytical
techniques (neutron scattering, scanning force microscopy) either lack spatial
information or nanoscale resolution. Using advanced analytical (scanning) transmission
electron microscopy ((S)TEM), we provide real space information on polymer domain
morphology and interfaces between polystyrene (PS) and polymethylmethacrylate
(PMMA) in cylinder- and lamellae-forming BCPs at highest resolution. This allows
us to correlate the internal structure of polymer domains with line edge roughnesses,
interface widths and domain sizes. STEM is employed for high-resolution imaging,
electron energy loss spectroscopy and energy filtered TEM (EFTEM) spectroscopic
imaging for material identification and EFTEM thickness mapping for visualisation
of material densities at defects. The volume fraction of non-phase separated polymer
species can be analysed by EFTEM. These methods give new insights into the morphology
of polymer domains the exact knowledge of which will allow to improve pattern
quality for nanolithography.

text: The aggregation of human islet amyloid polypeptide (hIAPP) plays a
major role in the pathogenesis of type 2 diabetes mellitus (T2DM), and numerous
strategies for controlling hIAPP aggregation have been investigated so far. In
particular, several organic and inorganic nanoparticles (NPs) have shown the potential
to influence the aggregation of hIAPP and other amyloidogenic proteins and peptides.
In addition to conventional NPs, DNA nanostructures are receiving more and more
attention from the biomedical field. Therefore, in this work, we investigated
the effects of two different DNA origami nanostructures on hIAPP aggregation.
To this end, we employed in situ turbidity measurements and ex situ atomic force
microscopy (AFM). The turbidity measurements revealed a retarding effect of the
DNA nanostructures on hIAPP aggregation, while the AFM results showed the co-aggregation
of hIAPP with the DNA origami nanostructures into hybrid peptide–DNA aggregates.
We assume that this was caused by strong electrostatic interactions between the
negatively charged DNA origami nanostructures and the positively charged peptide.
Most intriguingly, the influence of the DNA origami nanostructures on hIAPP aggregation
differed from that of genomic double-stranded DNA (dsDNA) and appeared to depend
on DNA origami superstructure. DNA origami nanostructures may thus represent a
novel route for modulating amyloid aggregation in vivo.

text: Rod-like and sheet-like nano-particles made of desoxyribonucleic acid
(DNA) fabricated by the DNA origami method (base sequence-controlled self-organized
folding of DNA) are dispersed in a lyotropic chromonic liquid crystal made of
an aqueous solution of disodium cromoglycate. The respective liquid crystalline
nanodispersions are doped with a dichroic fluorescent dye and their orientational
order parameter is studied by means of polarized fluorescence spectroscopy. The
presence of the nano-particles is found to slightly reduce the orientational order
parameter of the nematic mesophase. Nano-rods with a large length/width ratio
tend to preserve the orientational order, while more compact stiff nano-rods and
especially nano-sheets reduce the order parameter to a larger extent. In spite
of the difference between the sizes of the DNA nano-particles and the rod-like
columnar aggregates forming the liquid crystal, a similarity between the shapes
of the former and the latter seems to be better compatible with the orientational
order of the liquid crystal.

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: Large Co-MOF-74 crystals of a few hundred micrometers were prepared by solvothermal
synthesis, and their structure and morphology were characterized by scanning electron
microscopy (SEM), IR, and Raman spectroscopy. The hydrothermal stability of the
material up to 60 °C at 93% relative humidity was verified by temperature-dependent
XRD. Proton conductivity was studied by impedance spectroscopy, using a single
crystal. By varying the relative humidity (70–95%), temperature (21–60 °C), and
orientation of the crystal relative to the electrical potential, it was found
that proton conduction occurs predominantly through the linear, unidirectional
(1D) micropore channels of Co-MOF-74, and that water molecules inside the channels
are responsible for the proton mobility by a Grotthuss-type mechanism.

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: We describe the synthesis of mesoporous Al2O3 and MgO layers on silicon wafer
substrates by using poly(dimethylacrylamide) hydrogels as porogenic matrices.
Hydrogel films are prepared by spreading the polymer through spin-coating, followed
by photo-cross-linking and anchoring to the substrate surface. The metal oxides
are obtained by swelling the hydrogels in the respective metal nitrate solutions
and subsequent thermal conversion. Combustion of the hydrogel results in mesoporous
metal oxide layers with thicknesses in the μm range and high specific surface
areas up to 558 m2∙g−1. Materials are characterized by SEM, FIB ablation, EDX,
and Kr physisorption porosimetry.

text: The utilization and preparation of functional hybrid films for optical sensing
applications and membranes is of utmost importance. In this work, we report the
convenient and scalable preparation of self-crosslinking particle-based films
derived by directed self-assembly of alkoxysilane-based cross-linkers as part
of a core-shell particle architecture. The synthesis of well-designed monodisperse
core-shell particles by emulsion polymerization is the basic prerequisite for
subsequent particle processing via the melt-shear organization technique. In more
detail, the core particles consist of polystyrene (PS) or poly(methyl methacrylate)
(PMMA), while the comparably soft particle shell consists of poly(ethyl acrylate)
(PEA) and different alkoxysilane-based poly(methacrylate)s. For hybrid film formation
and convenient self-cross-linking, different alkyl groups at the siloxane moieties
were investigated in detail by solid-state Magic-Angle Spinning Nuclear Magnetic
Resonance (MAS, NMR) spectroscopy revealing different crosslinking capabilities,
which strongly influence the properties of the core or shell particle films with
respect to transparency and iridescent reflection colors. Furthermore, solid-state
NMR spectroscopy and investigation of the thermal properties by differential scanning
calorimetry (DSC) measurements allow for insights into the cross-linking capabilities
prior to and after synthesis, as well as after the thermally and pressure-induced
processing steps. Subsequently, free-standing and self-crosslinked particle-based
films featuring excellent particle order are obtained by application of the melt-shear
organization technique, as shown by microscopy (TEM, SEM).

CMK-3 carbon matrix by solution-based impregnation. Thermal conversion of the
metal nitrates into the respective metal oxides, and subsequent removal of the
carbon matrix by thermal combustion, provides a versatile means to prepare mesoporous
metal oxides (so-called nanocasting). This study aims to monitor the thermally
induced processes by thermogravimetric analysis (TGA), coupled with mass ion detection
(MS). The highly dispersed metal nitrates in the pores of the carbon matrix tend
to react to the respective metal oxides at lower temperature than reported in
the literature for pure, i.e., carbon-free, metal nitrates. The subsequent thermal
combustion of the CMK-3 carbon matrix also occurs at lower temperature, which
is explained by a catalytic effect of the metal oxides present in the pores. This
catalytic effect is particularly strong for oxides of redox active metals, such
as transition group VII and VIII metals (Mn, Fe, Co, Ni), Cu, and Ce.
