Universal Casimir attraction between filaments at the cell scale

The electromagnetic Casimir interaction between dielectric objects immersed in salted water includes a universal contribution that is not screened by the solvent and therefore long-ranged. Here, we study the geometry of two parallel dielectric cylinders. W ...

Recent Advances in Piezoelectric Materials for Electromechanical Transducer Applications

Dragan Damjanovic

Ferroelectricity has made a huge impact on science and technology since Joseph Valasek (then a Ph.D. student at the University of Minnesota) discovered it in 1920, a little longer than 100 years ago. Whereas Dr. Valasek's original research was motivated by ...

Energy hub-based optimal planning framework for user-level integrated energy systems: Considering synergistic effects under multiple uncertainties

Chengzhou Li, François Maréchal

The design of user-level integrated energy systems is challenged by a variety of combinations of energy converters, complex cascade utilization of multiple energy flows, as well as sequential matching between stochastic energy resources and periodic energy ...

Mapping the local dielectric constant of a biological nanostructured system

Juan Pablo Vasco Cano

The aim of this work is to determine the varying dielectric constant of a biological nanostructured system via electrostatic force microscopy (EFM) and to show how this method is useful to study natural photonic crystals. We mapped the dielectric constant ...

Integration of solar energy with industrial processes

Anna Sophia Wallerand

Solar energy offers a great potential for integration with industrial processes, which conventionally rely on fossil fuels to provide energy. The seasonal, daily, and regional dependence of solar energy alongside the scarcity of space or financial resource ...

Concurrent Voltage Control and Dispatch of Active Distribution Networks by means of Smart Transformer and Storage

Mario Paolone, Fabrizio Sossan, Konstantina Christakou

Dispatching active distribution networks is expected to play an important role in the smart grid technologies. Voltage control is also starting to be widely proposed to avoid voltage violations in the electrical grid. The integration of the storage in the ...

Thermally induced voltage shift in capacitance-voltage characteristics and its relation to oxide/semiconductor interface states in Ni/Al2O3/InAlN/GaN heterostructures

Nicolas Grandjean, Jean-François Carlin

The Ni/Al2O3/InAlN/AlN/GaN metal-oxide-semiconductor heterostructure (MOS-H) is investigated using capacitance-voltage and capacitance-time characteristics in the temperature range of 25-300 degrees C. An anomalous positive voltage shift of the capacitance ...

Evidence for dielectric aging due to progressive 180 degrees domain wall pinning in polydomain Pb(Zr0.45Ti0.55)O-3 thin films

Alexander Tagantsev, Nava Setter, Dragan Damjanovic, Igor Stolichnov

An evidence that the dielectric aging in the polydomain Pb(Zr0.45Ti0.55)O-3 thin films is controlled by progressive pinning of 180 degrees domain walls is presented. To provide such a conclusion, we use a general method, which is based on the study of the ...

Trap-limited transport in rubrene transistors

Libero Zuppiroli, Marie-Noëlle Bussac

The charge carrier mobility in the transport channel of an organic transistor is estimated within the framework of a trap-and-release model. The model accounts for the observed dependence of the mobility on the dielectric constant "epsilon" of the gate ins ...
