Deciphering the Mechanisms of Bacterial Inactivation on HiPIMS Sputtered CuxO-FeOx-PET Surfaces: From Light Absorption to Catalytic Bacterial Death

The production of nontoxic, affordable, and efficient antibacterial surfaces is key to the well-being of our societies. In this aim, antibacterial thin films have been prepared using earth-abundant metals deposited using high-power impulse magnetron sputte ...

Large impact of strain on the electro-optic effect in (Ba, Sr)TiO3 thin films: Experiment and theoretical comparison

Alexander Tagantsev

(001)-epitaxial (Ba0.5Sr0.5)TiO3 (BST) thin films with different magnitudes of compressive strain were fabricated on SrRuO3/SrTiO3 substrates by pulsed laser deposition, and their electro-optic (EO) properties were characterized by modulation ellipsometry ...

Crystal Phase Tuning in Planar Films of III-V Semiconductors

Anna Fontcuberta i Morral, Kirsten Emilie Moselund, Nicolas Tappy

We report on the control of the crystal phase of micron-sized planar III-V semiconductor films grown on top of standard (001) oriented substrates. We achieve this by confining the MOCVD process using SiO2 templates and selecting specific growth planes. We ...

Novel daylighting system based on advanced embedded optical microstructures for various facade orientation and climates

Jing Gong

The design of highly glazed building has become a worldwide trend in modern architecture. However, glazing may induce large thermal loss in winter while increase cooling load in summer, and it may also cause glare. In order to solve the problems, a novel m ...

GaN Quantum Dots for Room Temperature Excitonic Physics

Sebastian Pascal Tamariz Kaufmann

Quantum dots (QDs) are the result of quantum confinement in the three spatial directions, as such they exhibit remarkable properties, of which the most important is perhaps the absence of a continuum of states. The allowed energetic levels are discrete, si ...

Optimized Electrolyte Loading and Active Film Thickness for Sandwich Polymer Light-Emitting Electrochemical Cells

Frank Nüesch, Roland Hany, Matthias Diethelm

Effects of ion concentration and active layer thickness play a critical role on the performance of light-emitting electrochemical cells. Expanding on a pioneering materials system comprising the super yellow (SY) polymer and the electrolyte trimethylolprop ...

Optimizing Mesostructured Silver Catalysts for Selective Carbon Dioxide Conversion into Fuels

Sophia Haussener, Silvan Suter

Mesostructured silver catalysts have shown a substantial rise in reaction selectivity for the conversion of CO2 into fuels with increasing thickness of ordered, inverse-opal films. The challenge lies in the optimization of the morphology to maximize the CO ...

Controlling topology, dynamics and function of polymer brushes via post-polymerization modification

Piotr Mocny

Polymer brushes are a class of thin coatings, where each of chains is tethered to the underlying substrate via one chain end. Densely grafted polymer brushes feature a stretched chain conformation, which in a unique way enhances their lubrication and non-b ...
