text: Metallic nanoparticles co-functionalised with monolayers of UV- and CO2-sensitive
ligands were prepared and shown to respond to these two types of stimuli reversibly
and in an orthogonal fashion. The composition of the coating could be tailored
to yield nanoparticles capable of aggregating exclusively when both UV and CO2
were applied at the same time, analogously to the behaviour of an AND logic gate.

text: 'Photoswitching in densely packed azobenzene self-assembled monolayers (SAMs)
is strongly affected by steric constraints and excitonic coupling between neighboring
chromophores. Therefore, control of the chromophore density is essential for enhancing
and manipulating the photoisomerization yield. We systematically compare two methods
to achieve this goal: First, we assemble monocomponent azobenzene–alkanethiolate
SAMs on gold nanoparticles of varying size. Second, we form mixed SAMs of azobenzene–alkanethiolates
and “dummy” alkanethiolates on planar substrates. Both methods lead to a gradual
decrease of the chromophore density and enable efficient photoswitching with low-power
light sources. X-ray spectroscopy reveals that coadsorption from solution yields
mixtures with tunable composition. The orientation of the chromophores with respect
to the surface normal changes from a tilted to an upright position with increasing
azobenzene density. For both systems, optical spectroscopy reveals a pronounced
excitonic shift that increases with the chromophore density. In spite of exciting
the optical transition of the monomer, the main spectral change in mixed SAMs
occurs in the excitonic band. In addition, the photoisomerization yield decreases
only slightly by increasing the azobenzene–alkanethiolate density, and we observed
photoswitching even with minor dilutions. Unlike in solution, azobenzene in the
planar SAM can be switched back almost completely by optical excitation from the
cis to the original trans state within a short time scale. These observations
indicate cooperativity in the photoswitching process of mixed SAMs.'

text: Self-assembly of inorganic nanoparticles has been studied extensively for
particles having different sizes and compositions. However, relatively little
attention has been devoted to how the shape and surface chemistry of magnetic
nanoparticles affects their self-assembly properties. Here, we undertook a combined
experiment–theory study aimed at better understanding of the self-assembly of
cubic magnetite (Fe3O4) particles. We demonstrated that, depending on the experimental
parameters, such as the direction of the magnetic field and nanoparticle density,
a variety of superstructures can be obtained, including one-dimensional filaments
and helices, as well as C-shaped assemblies described here for the first time.
Furthermore, we functionalized the surfaces of the magnetic nanocubes with light-sensitive
ligands. Using these modified nanoparticles, we were able to achieve orthogonal
control of self-assembly using a magnetic field and light.

text: The detection of electron motion and electronic wave-packet dynamics is one
of the core goals of attosecond science. Recently, choosing the nitric oxide molecule
as an example, we have introduced and demonstrated an experimental approach to
measure coupled valence electronic and rotational wave packets using high-order-harmonic-generation
(HHG) spectroscopy [Kraus et al., Phys. Rev. Lett. 111, 243005 (2013)]. A short
outline of the theory to describe the combination of the pump and HHG probe process
was published together with an extensive discussion of experimental results [Baykusheva
et al., Faraday Discuss. 171, 113 (2014)]. The comparison of theory and experiment
showed good agreement on a quantitative level. Here, we present the theory in
detail, which is based on a generalized density-matrix approach that describes
the pump process and the subsequent probing of the wave packets by a semiclassical
quantitative rescattering approach. An in-depth analysis of the different Raman
scattering contributions to the creation of the coupled rotational and electronic
spin-orbit wave packets is made. We present results for parallel and perpendicular
linear polarizations of the pump and probe laser pulses. Furthermore, an analysis
of the combined rotational-electronic density matrix in terms of irreducible components
is presented that facilitates interpretation of the results.
