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: "Abstract\r\n \r\n Objective\r\n
\ External focus (EF) of attention leads to improved balance
performance. Consideration of the neuromodulatory effects of EF may inform its
clinical utility in addressing neuroplastic impairments after musculoskeletal
injuries. We aimed to determine whether electrocortical activity and balance performance
changed with attentional foci that prioritized differing sensory feedback and
whether changes in electrocortical activity and balance were associated.\r\n
\ \r\n \r\n Methods\r\n
\ Individuals who were healthy (n = 15) performed a single-limb
balance task under 3 conditions: internal focus (IF), somatosensory focus [EF
with a baton (EF-baton)], and visual focus [EF with a laser (EF-laser)]. Electrocortical
activity and postural sway were recorded concurrently using electroencephalography
and a triaxial force plate. Electroencephalographic signals were decomposed, localized,
and clustered to generate power spectral density in θ and α-2 frequency bands.
Postural sway signals were analyzed with center-of-pressure sway metrics (eg,
area, distance, velocity) and knee angle. The relationship between percent change
in clustered brain activity and task performance metrics was assessed.\r\n
\ \r\n \r\n Results\r\n
\ Both EF conditions resulted in increased cortical activity
and improved balance performance compared to IF. EF-laser had the largest effect,
demonstrating increased frontal θ power (d = 0.64), decreased central θ power
(d = −0.30), and decreased bilateral motor, bilateral parietal, and occipital
α-2 power (d = −1.38 to −4.27) as well as a shorter path distance (d = −0.94)
and a deeper (d = 0.70) and less variable (d = −1.15) knee angle than IF. Weak
to moderate associations exist between increases in cortical activity and improved
balance performance (ρ = 0.405–0.584).\r\n \r\n
\ \r\n Conclusions\r\n
\ EF resulted in increased cortical activity associated
with cognitive, motor, somatosensory, and visual processing. EF-laser, which prioritized
visual feedback, had the largest and broadest effects. Changes in cortical activity
resulting from EF were independently associated with improved balance performance.\r\n
\ \r\n \r\n Impact\r\n
\ This study demonstrates that goal-oriented attention
results in functional increases in brain activity compared to internally directed
self-focus. These results suggest EF may target neurophysiologic impairments and
improve balance in clinical populations.\r\n "

text: Whereas initial findings have already identified cortical patterns
accompanying proprioceptive deficiencies in patients after anterior cruciate ligament
reconstruction (ACLR), little is known about compensatory sensorimotor mechanisms
for re-establishing postural control. Therefore, the aim of the present study
was to explore leg dependent patterns of cortical contributions to postural control
in patients 6 weeks following ACLR. A total of 12 patients after ACLR (25.1 ±
3.2 years, 178.1 ± 9.7 cm, 77.5 ± 14.4 kg) and another 12 gender, age, and activity
matched healthy controls participated in this study. All subjects performed 10
× 30 s. single leg stances on each leg, equipped with 64-channel mobile electroencephalography
(EEG). Postural stability was quantified by area of sway and sway velocity. Estimations
of the weighted phase lag index were conducted as a cortical measure of functional
connectivity. The findings showed significant group × leg interactions for increased
functional connectivity in the anterior cruciate ligament (ACL) injured leg, predominantly
including fronto−parietal [F(1, 22)
= 8.41, p ≤ 0.008, η2 = 0.28],
fronto−occipital [F(1, 22) = 4.43,
p ≤ 0.047, η2 = 0.17], parieto−motor
[F(1, 22) = 10.30, p
≤ 0.004, η2 = 0.32], occipito−motor [F(1,
22) = 5.21, p ≤ 0.032, η2
= 0.19], and occipito−parietal [F(1, 22)
= 4.60, p ≤ 0.043, η2 = 0.17]
intra−hemispherical connections in the contralateral hemisphere and occipito−motor
[F(1, 22) = 7.33, p
≤ 0.013, η2 = 0.25] on the ipsilateral hemisphere to the
injured leg. Higher functional connectivity in patients after ACLR, attained by
increased emphasis of functional connections incorporating the somatosensory and
visual areas, may serve as a compensatory mechanism to control postural stability
of the injured leg in the early phase of rehabilitation. These preliminary results
may help to develop new neurophysiological assessments for detecting functional
deficiencies after ACLR in the future.

text: Abstract Mobile Electroencephalography (EEG)
provides insights into cortical contributions to postural control. Although changes
in theta (4–8 Hz) and alpha frequency power (8–12 Hz) were shown to reflect attentional
and sensorimotor processing during balance tasks, information about the effect
of stance leg on cortical processing related to postural control is lacking. Therefore,
the aim was to examine patterns of cortical activity during single-leg stance
with varying surface stability. EEG and force plate data from 21 healthy males
(22.43 ± 2.23 years) was recorded during unipedal stance (left/right) on a stable
and unstable surface. Using source-space analysis, power spectral density was
analyzed in the theta, alpha-1 (8–10 Hz) and alpha-2 (10–12 Hz) frequency bands.
Repeated measures ANOVA with the factors leg and surface stability revealed significant
interaction effects in the left (p = 0.045, ηp2
= 0.13) and right motor clusters (F = 16.156; p
= 0.001, ηp2
= 0.41). Furthermore, significant main effects for surface stability were observed
for the fronto-central cluster (theta), left and right motor (alpha-1), as well
as for the right parieto-occipital cluster (alpha-1/alpha-2). Leg dependent changes
in alpha-2 power may indicate lateralized patterns of cortical processing in motor
areas during single-leg stance. Future studies may therefore consider lateralized
patterns of cortical activity for the interpretation of postural deficiencies
in unilateral lower limb injuries.

text: We perform a theoretical analysis of the structural and electronic properties
of sodium potassium niobate K1-xNaxNbO3 in the orthorhombic room-temperature phase,
based on density-functional theory in combination with the supercell approach.
Our results for x=0 and x=0.5 are in very good agreement with experimental measurements
and establish that the lattice parameters decrease linearly with increasing Na
contents, disproving earlier theoretical studies based on the virtual-crystal
approximation that claimed a highly nonlinear behavior with a significant structural
distortion and volume reduction in K0.5Na0.5NbO3 compared to both end members
of the solid solution. Furthermore, we find that the electronic band gap varies
very little between x=0 and x=0.5, reflecting the small changes in the lattice
parameters.

text: Uniaxial anisotropy in nonlinear birefringent crystals limits the
efficiency of nonlinear optical interactions and breaks the spatial symmetry of
light generated in the parametric down-conversion (PDC) process. Therefore, this
effect is usually undesirable and must be compensated for. However, high gain
may be used to overcome the destructive role of anisotropy in order to generate
bright two-mode correlated twin-beams. In this work, we provide a rigorous theoretical
description of the spatial properties of bright squeezed light in the presence
of strong anisotropy. We investigate a single crystal and a system of two crystals
with an air gap (corresponding to a nonlinear SU(1,1) interferometer) and demonstrate
the generation of bright correlated twin-beams in such configurations at high
gain due to anisotropy. We explore the mode structure of the generated light and
show how anisotropy, together with crystal spacing, can be used for radiation
shaping.
