text: Hydrothermal carbonization (HTC) is an efficient thermochemical method for
the conversion of organic feedstock to carbonaceous solids. HTC of different saccharides
is known to produce microspheres (MS) with mostly Gaussian size distribution,
which are utilized as functional materials in various applications, both as pristine
MS and as a precursor for hard carbon MS. Although the average size of the MS
can be influenced by adjusting the process parameters, there is no reliable mechanism
to affect their size distribution. Our results demonstrate that HTC of trehalose,
in contrast to other saccharides, results in a distinctly bimodal sphere diameter
distribution consisting of small spheres with diameters of (2.1 ± 0.2) μm and
of large spheres with diameters of (10.4 ± 2.6) μm. Remarkably, after pyrolytic
post-carbonization at 1000 °C the MS develop a multimodal pore size distribution
with abundant macropores > 100 nm, mesopores > 10 nm and micropores < 2 nm, which
were examined by small-angle X-ray scattering and visualized by charge-compensated
helium ion microscopy. The bimodal size distribution and hierarchical porosity
provide an extraordinary set of properties and potential variables for the tailored
synthesis of hierarchical porous carbons, making trehalose-derived hard carbon
MS a highly promising material for applications in catalysis, filtration, and
energy storage devices.

text: Faradaic reactions including charge transfer are often accompanied with diffusion
limitation inside the bulk. Conductive two-dimensional frameworks (2D MOFs) with
a fast ion transport can combine both - charge transfer and fast diffusion inside
their porous structure. To study remaining diffusion limitations caused by particle
morphology, different synthesis routes of Cu-2,3,6,7,10,11-hexahydroxytriphenylene
(Cu3(HHTP)2), a copper-based 2D MOF, are used to obtain flake- and rod-like MOF
particles. Both morphologies are systematically characterized and evaluated for
redox-active Li+ ion storage. The redox mechanism is investigated by means of
X-ray absorption spectroscopy, FTIR spectroscopy and in situ XRD. Both types are
compared regarding kinetic properties for Li+ ion storage via cyclic voltammetry
and impedance spectroscopy. A significant influence of particle morphology for
2D MOFs on kinetic aspects of electrochemical Li+ ion storage can be observed.
This study opens the path for optimization of redox active porous structures to
overcome diffusion limitations of Faradaic processes.

text: The proton conductivity of two coordination networks, [Mg(H2O)2(H3L)]·H2O
and [Pb2(HL)]·H2O (H5L
= (H2O3PCH2)2-NCH2-C6H4-SO3H),
is investigated by AC impedance spectroscopy. Both materials contain the same
phosphonato-sulfonate linker molecule, but have clearly different crystal structures,
which has a strong effect on proton conductivity. In the Mg-based coordination
network, dangling sulfonate groups are part of an extended hydrogen bonding network,
facilitating a “proton hopping” with low activation energy; the material shows
a moderate proton conductivity. In the Pb-based metal-organic framework, in contrast,
no extended hydrogen bonding occurs, as the sulfonate groups coordinate to Pb2+,
without forming hydrogen bonds; the proton conductivity is much lower in this
material.

text: Near ambient pressure XPS in nitrogen atmosphere was utilized to investigate
gas-solid interactions within porous SiO2 films ranging from 30 to 75 nm thickness.
The films were differentiated in terms of porosity and roughness. The XPS N1s
core levels of the N2 gas in presence of the SiO2 samples showed variations in
width, binding energy and line shape. The width correlated with the surface charge
induced in the dielectric films upon X-ray irradiation. The observed different
binding energies observed for the N1s peak can only partly be associated with
intrinsic work function differences between the samples, opening the possibility
that the effect of physisorption at room temperature could be detected by a shift
in the measured binding energy. However, the signals also show an increasing asymmetry
with rising surface charge. This might be associated with the formation of vertical
electrical gradients within the dielectric porous thin films, which complicates
the assignment of binding energy positions to specific surface-related effects.
With the support of Monte Carlo and first principles density functional theory
calculations, the observed shifts were discussed in terms of the possible formation
of transitory dipoles upon N2 physisorption within the porous SiO2 films.

text: In the spatial confinement of cylindrical mesopores with diameters of a few
nanometers, water molecules experience restrictions in hydrogen bonding. This
leads to a different behavior regarding the molecular orientational freedom (‘structure
of water') compared to the bulk liquid state. In addition to the pore size, the
behavior is also strongly affected by the strength of the pore wall-to-water interactions,
that is, the pore wall polarity. In this work, this is studied both experimentally
and theoretically. The surface polarity of mesoporous silica (SiO2) is modified
by functionalization with trimethylsilyl moieties, resulting in a change from
a hydrophilic (pristine) to a hydrophobic pore wall. The mesopore surface is characterized
by N2 and H2O sorption experiments. Those results are combined with IR spectroscopy
to investigate pore wall-to-water interactions leading to different structures
of water in the mesopore. Furthermore, the water's structure is studied theoretically
to gain deeper insight into the interfacial interactions. For this purpose, the
structure of water is analyzed by pairing densities, coordination, and angular
distributions with a novel adaptation of surface-specific sum-frequency generation
calculation for pore environments.

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: With the rapid advances of functional dielectric metasurfaces and their integration
on on-chip nanophotonic devices, the necessity of metasurfaces working in different
environments, especially in biological applications, arose. However, the metasurfaces’
performance is tied to the unit cell’s efficiency and ultimately the surrounding
environment it was designed for, thus reducing its applicability if exposed to
altering refractive index media. Here, we report a method to increase a metasurface’s
versatility by covering the high-index metasurface with a low index porous SiO2
film, protecting the metasurface from environmental changes while keeping the
working efficiency unchanged. We show, that a covered metasurface retains its
functionality even when exposed to fluidic environments.

text: The free exciton transition (near-band-edge emission, NBE) of ZnO at ≈388
nm can be strongly enhanced and even stimulated by an underlying photonic structure.
1D Photonic crystals, so-called distributed Bragg reflectors, are utilized to
suppress the deep-level emission of ZnO (DLE, ≈500–530 nm). The reflector stacks
are fabricated in a layer-by-layer procedure by wet-chemical synthesis. They consist
of low-ε porous SiO2 layers and high-ε TiO2 layers. Varying the thickness of the
SiO2 layers allows tuning the optical bandgap in a wide range between ≈420 and
800 nm. A ZnO layer is deposited on top of the reflector stacks by sol–gel synthesis.
The spontaneous photoluminescence (PL) emission of the ZnO film is modulated by
the photonic structure. When the optical bandgap of the reflector is in resonance
with the deep-level emission of ZnO (DLE, ≈500–530 nm), then this defect-related
emission mode is suppressed. Strong NBE emission is observed even when the ZnO
layer does not show any NBE emission (due to low crystallinity) in the absence
of the photonic structure. With this cost-efficient synthesis method, emitters
for, e.g., luminescent gas sensors can be fabricated.

text: Powder X-ray diffraction (XRD) patterns of ordered mesoporous CMK-8 and CMK-9
carbon materials are simulated by geometric modeling. The materials are amorphous
at the atomic length scale but exhibit highly symmetric gyroidal structures at
the nanometer scale, corresponding to regular, continuous nanopore systems with
cubic symmetry. Their structures lead to characteristic low-angle XRD signatures.
We introduce a model based on geometrical considerations to simulate CMK-8 and
CMK-9 structures with variable volume fraction of carbon (vs. pore volume, i.e.,
variable 'pore wall thickness'). In addition, we also simulate carbon materials
with variable amounts of guest species (e.g., sulfur) residing in their pores.
The corresponding XRD patterns are calculated. The carbon volume fraction turns
out to have a significant impact on the relative diffraction peak intensities,
especially in case of CMK-9 carbon that features a bimodal porosity. Likewise,
the presence of guest species in the pores may also strongly affect the relative
peak intensities. Our study suggests that careful evaluation of experimental low-angle
XRD patterns of (real) CMK-8 or CMK-9 materials offers an opportunity to obtain
detailed information about the nanostructural properties in addition to the mere
identification of the pore systems geometry.

text: A comparison of infrared spectroscopic analytical approaches was made in order
to assess their applicability for internal structure characterization of SiO2
thin films. Markers for porosity and/or disorder based on the analysis of the
asymmetric stretching absorption band of SiO2 between 900−1350 cm−1 were discussed.
The shape of this band, which shows a well-defined LO–TO splitting, depends not
only on the inherent characteristics of the film under analysis but also on the
particular geometry of the IR experiment and the specific surface selection rules
of the substrate. Three types of SiO2 thin films with clearly defined porosity
ranging from dense films to mesoporous films were investigated by transmission
(at different incidence angles), direct specular reflection (at different angles),
and diffuse reflection. Two different types of substrate, metallic and semiconducting,
were used. The combined effect of substrate and specific technique in the final
shape of the band, was discussed, and the efficacy for their applicability to
the determination of porosity in thin SiO2 films was critically evaluated.

text: Tailor-made ordered mesoporous materials bear great potential in numerous
fields of application where large interfaces are required. However, the inherent
surfacechemical properties of conventional materials, such as silica, carbon or
organosilica, poses some limitations with respect to their application. Surface
manipulation by functionalization with chemically more reactive groups is one
way to improve materials for their desired purpose. Another approach is the design
of high surface-area composite materials. The surface manipulation, either by
functionalization or by introducing guest species, can be performed selectively.
This means that when several distinct, i.e. , hierarchical, types of surfaces
or pore systems exist in a material, each of them may be chosen for manipulation.
Several strategies can be identified to achieve this goal. Molecules or molecule
assemblies can be utilized to temporarily protect pores or surfaces (soft protection),
while manipulation occurs at the accessible sites. This approach is a recurring
motive in this review and can also be applied to rigid template matrices (hard
protection). Furthermore, the size of functionalization agents (size protection)
and their reactivity/diffusion (kinetic protection) into the pores can also be
utilized to achieve selectivity. In addition, challenges in the synthesis and
characterization of selectively manipulated ordered mesoporous materials are discussed.

text: In this report, a flame spray pyrolysis setup has been examined with various
in situ extraction methods of particle samples along the flame axis. First, two
precursor formulations leading to the formation of iron oxide nanoparticles were
used in a standardized SpraySyn burner system, and the final particle outcome
was characterized by a broad range of established powder characterization techniques
(TEM/HRTEM, SAXS, XRD, BET). The characterization of the powder products evidenced
that mostly homogeneous gas-to-particle conversion takes place when applying an
acidic precursor solution, whereas the absence of the acid leads to a dominant
droplet-to-particle pathway. Our study indicates that a droplet-to-particle-pathway
could be present even when processing the acidic formulation. However, even if
a secondary pathway might take place in this case as well, it is not dominant
and nearly negligible. Subsequently, the in situ particle structure evolution
was investigated for the dominant gas-to-particle pathway, and particles were
extracted along the flame axis for online SMPS and offline TEM/HRTEM analysis.
Due to the highly reactive conditions within the flame (high temperatures, turbulent
flow field, high particle number concentrations), the extraction of representative
samples from spray flames is challenging. In order to handle the reactive conditions,
two extraction techniques were tailored in this report. To extract an aerosol
sample within the flame for SMPS measurement, a Hole in a Tube probe was adjusted.
Thus, the mobility particle diameter as well as the corresponding distribution
widths were obtained at different heights above the burner along the flame axis.
For TEM/HRTEM image analysis, particle samples were collected thermophoretically
by means of a tailored shutter system. Since all sampling grids were protected
until reaching the flame axis and due to the low sampling time, momentary captures
of local particle structures could be extracted precisely. The particle morphologies
have clearly shown an evolution from spherical and paired particles in the flame
center to fractal and compact agglomerates at later synthesis stages.

text: Photodynamic therapy (PDT) using TiO2 nanoparticles has become an important
alternative treatment for different types of cancer due to their high photocatalytic
activity and high absorption of UV-A light. To potentiate this treatment, we have
coated commercial glass plates with TiO2 nanoparticles prepared by the sol–gel
method (TiO2-m), which exhibit a remarkable selectivity for the irreversible trapping
of cancer cells. The physicochemical properties of the deposited TiO2-m nanoparticle
coatings have been characterized by a number of complementary surface-analytical
techniques and their interaction with leukemia and healthy blood cells were investigated.
Scanning electron and atomic force microscopy verify the formation of a compact
layer of TiO2-m nanoparticles. The particles are predominantly in the anatase
phase and have hydroxyl-terminated surfaces as revealed by Raman, X-ray photoelectron,
and infrared spectroscopy, as well as X-ray diffraction. We find that lymphoblastic
leukemia cells adhere to the TiO2-m coating and undergo amoeboid-like migration,
whereas lymphocytic cells show distinctly weaker interactions with the coating.
This evidences the potential of this nanomaterial coating to selectively trap
cancer cells and renders it a promising candidate for the development of future
prototypes of PDT devices for the treatment of leukemia and other types of cancers
with non-adherent cells.

text: The tetratopic linker 1,1,2,2-tetrakis(4-phosphonophenyl)ethylene (H8TPPE)
was used to synthesize the three new porous metal–organic frameworks of composition
[M2(H2O)2(H2TPPE)]·xH2O (M = Al3+, Ga3+, Fe3+), denoted as M-CAU-53 under hydrothermal
reaction conditions, using the corresponding metal nitrates as starting materials.
The crystal structures of the compounds were determined ab initio from powder
X-ray diffraction data, revealing small structural differences. Proton conductivity
measurements were carried out, indicating different conductivity mechanisms. The
differences in proton conductivity could be linked to the individual structures.
In addition, a thorough characterization via thermogravimetry, elemental analysis,
IR-spectroscopy as well as N2- and H2O-sorption is given.

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: Porous tin dioxide is an important low-cost semiconductor applied in electronics,
gas sensors, and biosensors. Here, we present a versatile template-assisted synthesis
of nanostructured tin dioxide thin films using cellulose nanocrystals (CNCs).
We demonstrate that the structural features of CNC-templated tin dioxide films
strongly depend on the precursor composition. The precursor properties were studied
by using low-temperature nuclear magnetic resonance spectroscopy of tin tetrachloride
in solution. We demonstrate that it is possible to optimize the precursor conditions
to obtain homogeneous precursor mixtures and therefore highly porous thin films
with pore dimensions in the range of 10–20 nm (ABET = 46–64 m2 g–1, measured on
powder). Finally, by exploiting the high surface area of the material, we developed
a resistive gas sensor based on CNC-templated tin dioxide. The sensor shows high
sensitivity to carbon monoxide (CO) in ppm concentrations and low cross-sensitivity
to humidity. Most importantly, the sensing kinetics are remarkably fast; both
the response to the analyte gas and the signal decay after gas exposure occur
within a few seconds, faster than in standard SnO2-based CO sensors. This is attributed
to the high gas accessibility of the very thin porous film.

text: Micropatterned nanoporous aluminum oxide arrays are prepared on silicon wafer
substrates by using photopolymerized poly(dimethylacrylamide) hydrogels as porogenic
matrices. Hydrogel micropatterns are fabricated by spreading the prepolymer mixture
on the substrate, followed by UV photopolymerization through a micropatterned
mask. The hydrogel is covalently bonded to the substrate surface. Al2O3 is produced
by swelling the hydrogel in a saturated aluminum nitrate solution and subsequent
thermal conversion/calcination. As a result, micropatterned porous Al2O3 microdots
with heights in µm range and large specific surface areas up to 274 m2 g−1 are
obtained. Hence, the hydrogel fulfills a dual templating function, namely micropatterning
and nanoporosity generation. The impact of varying the photopolymerization time
on the properties of the products is studied. Samples are characterized by light
and confocal laser scanning microscopy, scanning electron microscopy, energy-dispersive
x-ray spectrometry, and Kr physisorption analysis.

text: Metal oxide inverse opals are interesting for various applications. To achieve
highly ordered inverse opal structures, one important issue during the colloidal
crystal templating procedure is to form a stable precursor network before the
template loses its structural integrity at high temperature. Using poly(methyl
methacrylate), PMMA, colloidal crystal templates, it is essential to consider
the physical and chemical changes of the precursors induced by the changes of
PMMA during the thermal conversion. For a systematic investigation of this matter,
we synthesized a variety of metal oxide inverse opals from the respective metal
nitrates, including Cr2O3, Ga2O3, Fe2O3, In2O3, CuO, CeO2, and ZnO, to compare
the effect of various modifications of precursors on the structural and optical
properties. When the nitrate precursors have a lower thermal stability than the
PMMA template, we have modified the metal nitrates by chelating or by polyacrylamide
gelation to form more stable precursor networks.

text: The proton conduction properties of a phosphonato-sulfonate-based coordination
polymer are studied by impedance spectroscopy using a single crystal specimen.
Two distinct conduction mechanisms are identified. Water-mediated conductance
along the crystal surface occurs by mass transport, as evidenced by a high activation
energy (0.54 eV). In addition, intrinsic conduction by proton ′hopping′ through
the interior of the crystal with a low activation energy (0.31 eV) is observed.
This latter conduction is anisotropic with respect to the crystal structure and
seems to occur through a channel along the c axis of the orthorhombic crystal.
Proton conduction is assumed to be mediated by sulfonate groups and non-coordinating
water molecules that are part of the crystal structure.
