Controlled deposition of titanium oxide overcoats by non-hydrolytic sol gel for improved catalyst selectivity and stability

Jeremy Luterbacher, Florent Emmanuel Héroguel, Yuan-Peng Du, Luca Silvioli

Advances in the synthetic control of surface nanostructures could improve the activity, selectivity and stability of heterogeneous catalysts. Here, we present a technique for the controlled deposition of TiO2 overcoats based on non-hydrolytic sol-gel chemi ...

Elastic strain engineering for ultralow mechanical dissipation

Tobias Kippenberg, Dalziel Joseph Wilson, Nils Johan Engelsen, Sergey Fedorov, Ryan Daniel Schilling, Amir Hossein Ghadimi

Extreme stresses can be produced in nanoscale structures, a feature which has been used to realize enhanced materials properties, such as the high mobility of silicon in modern transistors. Here we show how nanoscale stress can be used to realize exception ...

Long-lived Photo-Charges in 1D Helical Organic Semiconductor Nanostructures

Regina Judith Hafner

The formation of photoexcited states in organic semiconductors, their separation into long-lived or stable charge carriers, as well as the charge transport are critical processes relevant to several important research fields and emerging technologies. Whil ...

A bimetallic nanocoral Au decorated with Pt nanoflowers (bio)sensor for H2O2 detection at low potential

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Francesca Puppo

In this work, we have developed for the first time a method to make novel gold and platinum hybrid bimetallic nanostructures differing in shape and size. Au-Pt nanostructures were prepared by electrodeposition in two simple steps. The first step consists o ...

Nanoporous silicon tubes: the role of geometry in nanostructure formation and application to light emitting diodes

Anna Fontcuberta i Morral, Heidi Andrea Potts, Luca Francaviglia, Jelena Vukajlovic Plestina, Francesca Amaduzzi

Obtaining light emission from silicon has been the holy grail of optoelectronics over the last few decades. One of the most common methods for obtaining light emission from silicon is to reduce it to a nanoscale structure, for example by producing porous s ...

Where Does Energy Go in Electron Energy Loss Spectroscopy of Nanostructures?

Jürgen Brugger, Olivier Martin, Duncan Thomas Lindsay Alexander, Jérémy Butet, Valentin Flauraud, Gabriel David Bernasconi

Electron energy loss spectroscopy is a method of choice for the characterization of both the spatial and spectral properties of localized surface plasmon resonances. The energy lost by the impinging electrons is commonly explained by the Lorentz force acti ...
