text: Photosurfactants have shown considerable promise for enabling stimuli-responsive
control of the properties and motion of fluid interfaces. Recently, a number of
photoswitch chemistries have emerged to tailor the photoresponsive properties
of photosurfactants. However, systematic studies investigating how photoresponsive
surfactant behavior depends on the photochemical and photophysical properties
of the switch remain scarce. In this work, we develop synthetic schemes and surfactant
designs to produce a well-controlled library of photosurfactants to comparatively
assess the behavior of photoswitch chemistry on interfacial behavior. We employ
photoinduced spreading of droplets at fluid interfaces as a model for such studies.
We show that although photosurfactant response is largely guided by expected trends
with changes in polarity of the photoswitch, interfacial behavior also depends
nontrivially and sometimes counter-intuitively on the kinetics and mechanisms
of photoswitching, particularly at the interface of two solvents, as well as on
complex interactions with other surfactants. Understanding these complexities
enables the design of new photosurfactant systems and their optimization toward
responsive functions including triggered spreading, dewetting, and destabilization
of droplets on solid and fluid surfaces.

text: Surface roughness plays an important role in determining the mechanical properties,
wettability, and self-assembly in colloidal systems. In this work, we develop
a simple and fast method to produce rough colloidal SU-8 rods, bananas, and spheres,
via the nanoprecipitation of SU-8 in water. During this process, SU-8 nanospheres
are absorbed onto the surface of the colloidal SU-8 particles and then cross-linked
using UV-light. The size of the spherical asperities and the asperity density
are controlled by the concentration of SU-8 used during the nanoprecipitation
reaction. Fluorescent labeling of the rough SU-8 colloidal particles allows for
their confocal imaging, which demonstrates their stability at high packing fractions.
With these newly developed rough particles, we provide a colloidal model system
that allows for studies addressing the impact of surface roughness on materials
composed of anisotropic particles.

text: Azobenzenealkanethiols in self-assembled monolayers (SAMs) on Au(111) exhibit
reversible trans–cis photoisomerization when diluted with alkanethiol spacers.
Using these mixed SAMs, we show switching of the linear optical and second-harmonic
response. The effective switching of these surface optical properties relies on
a reasonably large cross section and a high photoisomerization yield as well as
a long lifetime of the metastable cis isomer. We quantified the switching process
by X-ray absorption spectroscopy. The cross sections for the trans–cis and cis–trans
photoisomerization with 365 and 455 nm light, respectively, are 1 order of magnitude
smaller than in solution. In vacuum, the 365 nm photostationary state comprises
50–74% of the molecules in the cis form, limited by their rapid thermal isomerization
back to the trans state. In contrast, the 455 nm photostationary state contains
nearly 100% trans-azobenzene. We determined time constants for the thermal cis–trans
isomerization of only a few minutes in vacuum and in a dry nitrogen atmosphere
but of more than 1 day in ambient air. Our results suggest that adventitious water
adsorbed on the surface of the SAM stabilizes the polar cis configuration of azobenzene
under ambient conditions. The back reaction rate constants differing by 2 orders
of magnitude underline the huge influence of the environment and, accordingly,
its importance when comparing various experiments.

text: The control of the phase distribution in multicomponent nanomaterials is critical
to optimize their catalytic performance. In this direction, while impressive advances
have been achieved in the past decade in the synthesis of multicomponent nanoparticles
and nanocomposites, element rearrangement during catalyst activation has been
frequently overseen. Here, we present a facile galvanic replacement-based procedure
to synthesize Co@Cu nanoparticles with narrow size and composition distributions.
We further characterize their phase arrangement before and after catalytic activation.
When oxidized at 350 °C in air to remove organics, Co@Cu core-shell nanostructures
oxidize to polycrystalline CuO-Co3O4 nanoparticles with randomly distributed CuO
and Co3O4 crystallites. During a posterior reduction treatment in H2 atmosphere,
Cu precipitates in a metallic core and Co migrates to the nanoparticle surface
to form Cu@Co core-shell nanostructures. The catalytic behavior of such Cu@Co
nanoparticles supported on mesoporous silica was further analyzed toward CO2 hydrogenation
in real working conditions.

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: 'Monodisperse Pd2Sn nanorods with tuned size and aspect ratio were prepared
by co-reduction of metal salts in the presence of trioctylphosphine, amine, and
chloride ions. Asymmetric Pd2Sn nanostructures were achieved by the selective
desorption of a surfactant mediated by chlorine ions. A preliminary evaluation
of the geometry influence on catalytic properties evidenced Pd2Sn nanorods to
have improved catalytic performance. In view of these results, Pd2Sn nanorods
were also evaluated for water denitration. '

text: Photoswelling of thin films of dichromated gelatin provides a basis for fabrication
of multilevel surface reliefs via sequential UV illumination through different
photomasks. The remarkable feature of this simple, benchtop technique is that
by adjusting irradiation times, film thickness, or its hydration state the heights
of the developed features can be varied from few nanometers to tens of microns.
After UV exposure, the surface structures can be replicated faithfully into either
soft or hard PDMS stamps.

text: A new experimental technique is described that uses reaction−diffusion phenomena
as a means of one-step microfabrication of complex, multilevel surface reliefs.
Thin films of dry gelatin doped with potassium hexacyanoferrate are chemically
micropatterned with a solution of silver nitrate delivered from an agarose stamp.
Precipitation reaction between the two salts causes the surface to deform. The
mechanism of surface deformation is shown to involve a sequence of reactions,
diffusion, and gel swelling/contraction. This mechanism is established experimentally
and provides a basis of a theoretical lattice-gas model that allows prediction
surface topographies emerging from arbitrary geometries of the stamped features.
The usefulness of the technique is demonstrated by using it to rapidly prepare
two types of mold for passive microfluidic mixers.
