Probing the buckling of pressurized spherical shells

Pedro Miguel Nunes Pereira de Almeida Reis, Dong Yan, Arefeh Abbasi

The prediction of the critical buckling conditions of shell structures is plagued by imperfection sensitivity. Non-destructive testing through point-load probing has been recently proposed to map the stability landscape of cylindrical shells. However, the ...

Seamless integration of design and Kirchhoff-Love shell analysis using analysis-suitable unstructured T-splines

Xiaodong Wei

Analysis-suitable T-splines (ASTS) including both extraordinary points and T-junctions are used to solve Kirchhoff-Love shell problems. Extraordinary points are required to represent surfaces with arbitrary topological genus. T-junctions enable local refin ...

Functional Elements for Quantum-Dot-Based Integrated Quantum Photonics

Antoine Maxime Delgoffe

Quantum Integrated Photonics (QIP) harnesses quantum-states of light on tiny chips, from generation to processing and eventual detection. Within this context, this thesis explores functional QIP elements resulting from the monolithic integration of semicon ...

Search for a Light CP-odd Higgs Boson and Low-Mass Dark Matter at the Belle Experiment

Olivier Schneider, Chao Wang, Yiming Li, Sun Hee Kim, Tara Nanut, Jun Yong Kim, Roberto Gargiani, Chang-Hyun Park, Seyed Sina Mirrazavi Salehian, Ke Huang, Arnaud Michel Gelb, Yong Chan Choi, Gaétan Charles Antoine Giriat, Linlin Cao, Martin Lubej, Wondwossen Wubie Eshetu, Mithilesh Nayak, Johannes Julius Thomas Marinus Swartjes, Jiayun Shen, Hiroyasu Yamamoto

We report on the first Belle search for a light CP-odd Higgs boson, A(0), that decays into low mass dark matter, chi, in final states with a single photon and missing energy. We search for events produced via the dipion transition (sic)(2S) -> (sic)(1S)pi( ...

Microfluidic Fabrication of Capsule Sensor Platform with Double-Shell Structure

Esther Amstad

Metal nanoparticles are frequently employed for the colorimetric detection of specific target molecules using an aggregation-induced shift of the localized surface plasmon resonance. However, metal nanoparticles dispersed in bulk solutions are prone to be ...

Selectively Permeable Double Emulsions

Esther Amstad, Irvine Lian Hao Ong

Natural organisms are made of different types of microcompartments, many of which are enclosed by cell membranes. For these organisms to display a proper function, the microcompartments must be selectively permeable. For example, cell membranes are typical ...

Cross-talk between emulsion drops: how are hydrophilic reagents transported across oil phases?

Bart Deplancke, Esther Amstad, Antoine Claude Jean Vian, Marjan Biocanin, Gianluca Nicolas Etienne

Emulsion drops are frequently used as vessels, for example, to conduct biochemical reactions in small volumes or to perform screening assays at high throughputs while consuming minimal sample volumes. These applications typically require drops that do not ...

Reducing the shell thickness of double emulsions using microfluidics

Esther Amstad, Antoine Claude Jean Vian

Double emulsion drops are well-suited templates to produce capsules whose dimensions can be conveniently tuned by adjusting those of the drops. To closely control the release kinetics of encapsulants, the composition and thickness of the capsule shell must ...

Nitrogen, Phosphorus, and Sulfur Co-Doped Hollow Carbon Shell as Superior Metal-Free Catalyst for Selective Oxidation of Aromatic Alkanes

Shuliang Yang, Li Peng

Metal-free heteroatom-doped carbocatalysts with a high surface area are desirable for catalytic reactions. In this study, we found an efficient strategy to prepare nitrogen, phosphorus, and sulfur co-doped hollow carbon shells (denote as NPS-HCS) with a su ...

Single-top t-channel production with off-shell and non-resonant effects

Valentin Hirschi

This Letter details and discusses the next-to-leading order QCD corrections to t-channel electro-weak W(+)bj production, where finite top-width effects are consistently taken into account. The computation is done within the AMC@NLO framework and includes b ...

Concrete shells – Towards efficient structures: Construction of an ellipsoidal concrete shell in Switzerland

Aurelio Muttoni, Miguel Fernández Ruiz

Concrete shells have been widely used in the past as economical and suitable solutions for a number of structures such as roofs, silos, cooling towers or offshore platforms. Taking advantage of their single or double curvature, bending moments and shear fo ...

Four-lepton production at hadron colliders: aMC@NLO predictions with theoretical uncertainties

Paolo Torrielli, Valentin Hirschi

We use aMC@NLO to study the production of four charged leptons at the LHC, performing parton showers with both HERWIG and PYTHIA6. Our underlying matrix element calculation features the full next-to-leading order O(alpha(S)) result and the O(alpha(2)(S)) c ...

A PSDT shell finite element formulation including structural damping

Thomas Gmür, Joël Cugnoni, Alain Schorderet, Marco Matter

This paper describes efficient C-0-compatible finite elements for modelling structurally damped laminated composite plates and shells under harmonic vibrations. Based upon a shear deformation theory of any order p (PSDT), the elements are well adapted for ...

Inkjet-Printed Multicolor Arrays of Highly Luminescent Nanocrystal-Based Nanocomposites

Jürgen Brugger, Vahid Fakhfouri, Joo Yeon Kim

Inkjet technology is a compelling method for the flexible and cost-effective printing of functional inks. We show that nanocomposite solutions based on polystyrene and differently sized core/shell-type nanocrystals (NCs) formed by a CdSe core coated with a ...
