  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.

  text: <jats:p>We devise a method to certify nonclassical features via correlations
    of phase-space distributions by unifying the notions of quasiprobabilities and
    matrices of correlation functions. Our approach complements and extends recent
    results that were based on Chebyshev's integral inequality \cite{BA19}. The method
    developed here correlates arbitrary phase-space functions at arbitrary points
    in phase space, including multimode scenarios and higher-order correlations. Furthermore,
    our approach provides necessary and sufficient nonclassicality criteria, applies
    to phase-space functions beyond <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>s</mml:mi></mml:math>-parametrized
    ones, and is accessible in experiments. To demonstrate the power of our technique,
    the quantum characteristics of discrete- and continuous-variable, single- and
    multimode, as well as pure and mixed states are certified only employing second-order
    correlations and Husimi functions, which always resemble a classical probability
    distribution. Moreover, nonlinear generalizations of our approach are studied.
    Therefore, a versatile and broadly applicable framework is devised to uncover
    quantum properties in terms of matrices of phase-space distributions.</jats:p>

  text: <jats:p>Semiconductor microcavities are frequently studied in the context
    of semiconductor lasers and in application-oriented fundamental research on topics
    such as linear and nonlinear polariton systems, polariton lasers, polariton pattern
    formation, and polaritonic Bose–Einstein condensates. A commonly used approach
    to describe theoretical properties includes a phenomenological single-mode equation
    that complements the equation for the nonlinear optical response (interband polarization)
    of the semiconductor. Here, we show how to replace the single-mode equation by
    a fully predictive transfer function method that, in contrast to the single-mode
    equation, accounts for propagation, retardation, and pulse-filtering effects of
    the incident light field traversing the distributed Bragg reflector (DBR) mirrors,
    without substantially increasing the numerical complexity of the solution. As
    examples, we use cavities containing GaAs quantum wells and transition-metal dichalcogenides
    (TMDs).</jats:p>

  text: Density-functional theory calculations of (TiO2)n clusters (n = 1–5) in the
    gas phase and adsorbed on pristine graphene as well as graphene quantum dots are
    presented. The cluster adsorption is found to be dominated by van der Waals forces.
    The electronic structure and in particular the excitation energies of the bare
    clusters and the TiO2/graphene composites are found to vary largely in dependence
    on the size of the respective constituents. This holds in particular for the energy
    and the spatial localization of the highest occupied and lowest unoccupied molecular
    orbitals. In addition to a substantial gap narrowing, a pronounced separation
    of photoexcited electrons and holes is predicted in some instances. This is expected
    to prolong the lifetime of photoexcited carriers. Altogether, TiO2/graphene composites
    are predicted to be promising photocatalysts with improved electronic and photocatalytic
    properties compared to bulk TiO2.

  text: <jats:title>Abstract</jats:title><jats:p>Semiconductor quantum dots are excellent
    candidates for ultrafast coherent manipulation of qubits by laser pulses on picosecond
    timescales or even faster. In inhomogeneous ensembles a macroscopic optical polarization
    decays rapidly due to dephasing, which, however, is reversible in photon echoes
    carrying complete information about the coherent ensemble dynamics. Control of
    the echo emission time is mandatory for applications. Here, we propose a concept
    to reach this goal. In a two-pulse photon echo sequence, we apply an additional
    resonant control pulse with multiple of 2<jats:italic>π</jats:italic> area. Depending
    on its arrival time, the control slows down dephasing or rephasing of the exciton
    ensemble during its action. We demonstrate for self-assembled (In,Ga)As quantum
    dots that the photon echo emission time can be retarded or advanced by up to 5
    ps relative to its nominal appearance time without control. This versatile protocol
    may be used to obtain significantly longer temporal shifts for suitably tailored
    control pulses.</jats:p>

  text: Vortices are topological objects representing the circular motion of a fluid.
    With their additional degree of freedom, the vorticity, they have been widely
    investigated in many physical systems and different materials for fundamental
    interest and for applications in data storage and information processing. Vortices
    have also been observed in non-equilibrium exciton-polariton condensates in planar
    semiconductor microcavities. There they appear spontaneously or can be created
    and pinned in space using ring-shaped optical excitation profiles. However, using
    the vortex state for information processing not only requires creation of a vortex
    but also efficient control over the vortex after its creation. Here we demonstrate
    a simple approach to control and switch a localized polariton vortex between opposite
    states. In our scheme, both the optical control of vorticity and its detection
    through the orbital angular momentum of the emitted light are implemented in a
    robust and practical manner.
