Scalable fabrication of functional nanostructures on stretchable substrates by capillary-assisted particle assembly and adhesion lithography

Henry Shao-Chi Yu

The fabrication of metallic nanostructures on stretchable substrates enables specific applications that exploit the combination of the nano-scale phenomena and the mechanical tunability of the physical dimensions of the nanostructures. Due to the large dif ...

Microstructure observations in compacted clays subjected to thermal loading

Lyesse Laloui, Melis Sütman, Roba Houhou

The response of clayey materials to thermal variation has been the subject of extensive studies, given the wide range of engineering applications which involve subjecting soils to substantial temperature fluctuations. A number of hypotheses have been propo ...

Quantifying Photoinduced Polaronic Distortions in Inorganic Lead Halide Perovskite Nanocrystals

Majed Chergui, Nicola Colonna, Michele Puppin, Giulia Fulvia Mancini, Thomas Charles Henry Rossi, Andre Al Haddad, Dominik Kinschel, Oliviero Cannelli, James Michael Budarz, Ludmila Maria Diniz Leroy

The development of next-generation perovskite-based optoelectronic devices relies critically on the understanding of the interaction between charge carriers and the polar lattice in out-of-equilibrium conditions. While it has become increasingly evident fo ...

Evaluation of secondary electron intensities for dopant profiling in ion implanted semiconductors: a correlative study combining SE, SIMS and ECV methods

Franz-Josef Haug, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Audrey Marie Isabelle Morisset, Philippe Wyss, Mario Joe Lehmann

This study evaluates the secondary electron (SE) dopant contrast in scanning electron microscopy (SEM) and helium ion microscopy (HIM) on boron implanted silicon sample. Complementary techniques like secondary ion mass spectrometry and electrochemical capa ...

Variations of intracellular density during the cell cycle arise from tip-growth regulation in fission yeast

Emrah Bostan, Pascal Damian Odermatt

Intracellular density impacts the physical nature of the cytoplasm and can globally affect cellular processes, yet density regulation remains poorly understood. Here, using a new quantitative phase imaging method, we determined that dry-mass density in fis ...

Experimental and numerical investigation of the thermo-mechanical behaviour of an energy sheet pile wall

Lyesse Laloui, Alessandro Francesco Rotta Loria, Marianna Adinolfi

One-of-a-kind experimental and numerical investigation is provided in this paper about energy sheet pile walls: earth retaining structures that embed heat exchanger probes within piles for the exploitation of shallow geothermal energy. The study resorts to ...

Coupled hydro-mechanical analysis of compacted bentonite behaviour during hydration

Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu

This study analyses the response of compacted bentonites upon hydration based on a coupled hydro-mechanical elasto-plastic framework. As an alternative to multi-porosity interpretation, the framework was selected based on the experimental evidence of adsor ...

On the numerical simulation of a confined cavitating tip leakage vortex under geometrical and operational uncertainties

Mohamed Farhat

The effects of operational and geometrical uncertainties on Tip Leakage Vortex (TLV) characteristics are investigated in the current research. Geometrical uncertainties are comprised of manufacturing tolerances or gradual geometry degradation over the time ...
