Piezoelectric and elastic properties of Al0.60Sc0.40N thin films deposited on patterned metal electrodes

Luis Guillermo Villanueva Torrijo, Silvan Stettler, Marco Liffredo, Nan Xu, Federico Peretti

Sc-doped aluminum nitride (AlScN) allows for piezoelectric devices with large electromechanical coupling and the benefits increase with larger Sc doping in the film. However, with a larger Sc concentration, the process window narrows, and it is necessary t ...

Stress effects on the impedance and ferroelectricity of PVDF-BiFeO3-MWCNT films using xanthan gum as dispersant

Frank Nüesch, Francis Owusu

Composite films based on dispersions of bismuth ferrite (BiFeO3) in polyvinylidene fluoride (PVDF) matrixes were prepared in the presence of multiwalled-carbon-nanotubes (MWCNT), using xanthan gum (XG) as dispersant. Films were prepared by spin coating and ...

Drops on the Underside of a Slightly Inclined Wet Substrate Move Too Fast to Grow

François Gallaire, Pierre-Thomas Paul Brun, Pier Giuseppe Ledda

Pendant drops suspended on the underside of a wet substrate are known to accumulate fluid from the surrounding thin liquid film, a process that often results in dripping. The growth of such drops is hastened by their ability to translate over an otherwise ...

Video Prediction Recalling Long-term Motion Context via Memory Alignment Learning

Hakgu Kim

Our work addresses long-term motion context issues for predicting future frames. To predict the future precisely, it is required to capture which long-term motion context (e.g., walking or running) the input motion (e.g., leg movement) belongs to. The bott ...

AcinoSet: A 3D Pose Estimation Dataset and Baseline Models for Cheetahs in the Wild

Alexander Mathis, Mackenzie Mathis

Animals are capable of extreme agility, yet understanding their complex dynamics, which have ecological, biomechanical and evolutionary implications, remains challenging. Being able to study this incredible agility will be critical for the development of n ...

High dynamic range image sharing with privacy protection

Touradj Ebrahimi, Evgeniy Upenik

Sharing pictures has become a very popular practice among consumers. Most recent cameras, displays, and smartphones can capture and display images in high dynamic range and wide colour gamut, contributing to an increase of this type of content. It is a wel ...

Quantification of Synthetic Polyesters from Biodegradable Mulch Films in Soils

Stephanie Christa Remke

Soil biodegradable mulch films composed of the polyester polybutylene adipate-co-terephthalate (PBAT) are being increasingly used in agriculture. Analytical methods to quantify PBAT in field soils are needed to assess its soil occurrence and fate. Here, we ...

Bretherton's buoyant bubble

John Martin Kolinski, Wassim Dhaouadi

When a buoyant bubble is inserted into a closed capillary that is slightly smaller than the capillary length, it appears stuck; exactly why this is so is a puzzle that has remained unanswered over the past 50 years. Recent calculations suggest that the bub ...

Covalent polymer network semiconducting thin-films and method for producing thereof

Kevin Sivula, Liang Yao

A method for manufacturing a semiconducting, organic, covalent polymer network thin film is disclosed, said method comprising the steps of deposing a solution comprising azide- containing monomers and electron-deficient alkyne-containing monomers onto a re ...

RF bias to suppress post-oxidation of mu c-Si:H films deposited by inductively-coupled plasma using a planar RF resonant antenna

Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne, Rémy Jacquier

One challenge for microcrystalline silicon (mu c-Si:H) deposition is to achieve high deposition rates while maintaining high quality films. In this work, an inductively-coupled plasma (ICP) is used to deposit mu c-Si:H on glass substrates by means of a nov ...

Engineering reversible elasticity in ductile and brittle thin films supported by a plastic foil

Stéphanie Lacour, Nicolas Vachicouras, Christina Myra Tringides

Reversible deformation is a unique property of elastic materials. Here, we design and fabricate highly stretchable multilayered films by patterning Y-shaped motifs through films of non- elastic materials, e.g. plastics, metals, ceramics. By adjusting the g ...

Digital transformation and open innovation ecosystems in the tilm industry: the case of the Movieday platform

Christopher Tucci, Gianluigi Viscusi

Digital technologies are transforming the film industry. Up until roughly a decade ago, the business model for film exhibition was based on theatrical release in combination with television sales and home cinema releases (video and DVD). Recently, many que ...

Three-dimensional Rayleigh–Taylor instability under a unidirectional curved substrate

François Gallaire, Pierre-Thomas Paul Brun, Gioele Mariano Nicolò Balestra, Nicolas Igor Jacques Kofman

We investigate the Rayleigh–Taylor instability of a thin liquid film coated on the inside of a cylinder whose axis is orthogonal to gravity. We are interested in the effects of geometry on the instability, and contrast our results with the classical case o ...

Zinc blende-wurtzite polytypism in nanocrystalline ZnO films

Christophe Ballif, Cécile Hébert, Aïcha Hessler-Wyser, Duncan Thomas Lindsay Alexander, Sylvain Nicolay, Arthur Brian Aebersold, Lorenzo Fanni

ZnO is commonly observed and assumed to crystallize fully in a wurtzite structure. Indeed, While polytypism between a wurtzite and a zinc blende phase is often seen in some II-VI compounds, it has only rarely been observed in ZnO. Here, by means of automat ...
