text: 'A complex random vector is called improper (noncircular) if it is correlated
with its complex conjugate. We consider measures for the degree of impropriety
that are invariant under linear transformation. These measures are functions of
the canonical correlations between the vector and its complex conjugate, which
have been termed the circularity coefficients. However, we show that these circularity
coefficients do not tell the whole story: Two random vectors with identical covariance
matrix and identical circularity coefficients can still behave differently in
second-order estimation and detection.'

text: Mesoporous SBA-15 (space group p6mm), KIT-6 (Ia3d) and KIT-5 (Fm3m) silicas,
exhibiting different 2-D and 3-D channel- or cage-like pore structure and pore
dimensions have been used as supports for iron oxide nanoparticles. The iron modification
of the silica was performed according to a frequently used impregnation technique
from aqueous iron nitrate solution. The materials were characterized by nitrogen
physisorption, X-ray diffraction, TEM–EDX, Moessbauer spectroscopy, and temperature-programmed
reduction (TPR) and tested in the catalytic decomposition of methanol. It is established
that the location and dispersion of iron oxide nanoparticles are affected by the
pore topology of the support. The most homogeneously dispersed iron oxide nanoparticles
are observed using silica host matrix exhibiting a 3-D channel-like structure
and pore diameters about 7 nm, and the thus-obtained composites exhibit high catalytic
activity and selectivity in methanol decomposition to CO and hydrogen. For all
the samples, characterized with a low mesopore volume and small pore diameters/pore
entrances, the formation of larger iron oxide particles, mainly located on the
outer surface, is observed. Inhomogeneously dispersed iron oxide particles with
a large fraction of isolated, strongly interacting with the support, iron species,
and possessing low catalytic activity and usually high selectivity to methane,
are found for the silicas with relatively larger pores/pore entrances.

text: Various measures to optimise the impregnation of mesoporous CMK-3 carbon and
SBA-15 silica matrices with metal nitrates for the synthesis of mesoporous metal
oxides by structure replication are investigated. The effect of surface modification
of the matrix pores, the choice of a solvent with suitable polarity, and the concentration
of the metal nitrate solution are studied in detail. The efficiency of pore loading
is monitored by nitrogen physisorption measurements. The creation of polar functions
at the pore surface of CMK-3 carbon is shown to increase the impregnation efficiency
substantially while maximizing the pore wall polarity of SBA-15 silica by increasing
the amount of free silanol groups does not have any significant impact. The choice
of a less polar solvent (THF instead of water) has a positive effect on the wettability
of CMK-3 carbon in the first impregnation cycle but turns out to be disadvantageous
in the second cycle; a similar trend is observed for variation of the metal salt
concentration.

text: Nanoporous semiconducting metal oxide materials (In2O3, WO3) with uniform
pore systems, large specific surface areas (80 m2 g−1), and pore-wall crystallinity
were prepared by structure replication, using KIT-6 silica as a template. The
products show improved properties as gas sensors (for methane or butanone) as
compared to non-porous samples. In addition, porous WO3 samples with comparable
porosity (prepared by conventional ‘soft templating’, using pluronic P123), which
are amorphous on the atomic length scale show poorer gas sensitivity, indicating
that crystallinity is a crucial factor in the sensing process.

text: Mesoporous ceria was synthesized by using both CMK-3 carbon and SBA-15 silica
as structure matrices. All products exhibit uniform mesopores with diameters of
5-6 nm in a two-dimensional periodic arrangement in addition to varying amounts
of interparticle porosity. The gas sensing properties (methane detection) of ordered
mesoporous ceria was compared to a non-porous sample.

text: The ultrafast dynamics of optical excitations in semiconductors and semiconductor
nanostructures can be computed on a microscopic theoretical basis using the semiconductor
Bloch equations. This set of equations allows one to nonperturbatively evaluate
light-field-induced intraband and interband excitations and is also well suited
for the analysis of many-body effects such as excitonic resonances and carrier-carrier
and carrier-phonon scattering processes. In this article we start with a description
of an experimental observation of coherent spin photocurrents, then we briefly
introduce the theoretical approach and review some results of our theory concerning
the microscopic description of the ultrafast coherent optical generation and the
temporal decay of charge and spin currents in semiconductor nanostructures. The
computed transients show an enhanced damping of the spin current relative to the
charge current as a consequence of Coulomb scattering between carriers with opposite
spin. The influence of quantum kinetic memory effects on the dynamics of the photocurrents
is analyzed by evaluating the scattering terms beyond the Markov approximation.
