Fundamental aspects to localize self-catalyzed III-V nanowires on silicon

Anna Fontcuberta i Morral, Martin George Friedl, Heidi Andrea Potts, Wonjong Kim, Jelena Vukajlovic Plestina, Lea Ghisalberti, Vladimir Dubrovskii, William Craig Carter

III-V semiconductor nanowires deterministically placed on top of silicon electronic platform would open many avenues in silicon-based photonics, quantum technologies and energy harvesting. For this to become a reality, gold-free site-selected growth is nec ...

Are Photonic Nanojets Achromatic?

Toralf Scharf, Myun Sik Kim, Michail Symeonidis

In this work we study the evolution of the photonic nanojet (PNJ) phenomenon as the ratio of the sphere's diameter over the illumination wavelength changes, for microspheres with diameters from 2 mu m to 100 mu m. We measure the focal point position by usi ...

Propagation of a planar hydraulic fracture perpendicular to the isotropy plane of a transversely isotropic material

Brice Tanguy Alphonse Lecampion, Haseeb Zia, Fatima-Ezzahra Moukhtari

We investigate the case of a hydraulic fracture (HF) propagating perpendicular to the isotropy plane of a transversely isotropic material: a relevant configuration for the growth of HFs in sedimentary rocks where fractures are propagating vertically across ...

Financial Ratios as Indicators of Economic Sustainability: A Quantitative Analysis for Swiss Dairy Farms

Ivo Philippe Baur

In agriculture, a rising number of sustainability assessments are available that also comprise financial ratios. In a literature review of farm management textbooks, taking account of the differences between European and North American practices and consid ...

The effective stiffness of modern unreinforced masonry walls

Katrin Beyer, Bastian Valentin Wilding

Code design of unreinforced masonry (URM) buildings is based on elastic anal-ysis, which requires as input parameter the effective stiffness of URM walls. Eurocode estimates the effective stiffness as 50% of the gross sectional elastic stiffness, but compa ...

Multimodal microstructure imaging: joint T2-relaxometry and diffusometry to estimate myelin, intracellular, extracellular, and cerebrospinal fluid properties

Jean-Philippe Thiran, Alessandro Daducci, Erick Jorge Canales Rodriguez, Marco Pizzolato

We propose a multimodal joint estimation that aims at exploiting the complementary information of diffusion and multi-echo spin echo data to disentangle the contributions and properties of the main tissue microstructure compartments. We recovered T2, diffu ...

Pore Size Manipulation in 3D Printed Cryogels Enables Selective Cell Seeding

Philippe Renaud, Ludovic Serex, Arnaud Bertsch, Thomas Michael Braschler, Ariane Rochat, Amélie Barbara Hildegarde Béduer, Aleksandra Filippova

Cryogels are macroporous materials that display remarkable properties, such as high pore interconnection, large surface to volume ratio, and high mechanical stability, making them good candidates for 3D cell culture. However, shaping cryogels remains chall ...

Stiffness, force and drift capacity of in-plane loaded modern unreinforced brick masonry walls

Bastian Valentin Wilding

In countries of low to moderate seismicity, such as Switzerland, unreinforced masonry (URM) is mainly used in residential buildings due to its good insulation capacity and fire resistance along with a fair compressive strength. URM walls however show a lim ...

Anomalous Vp/Vs ratios at seismic frequencies might evidence highly damaged rocks in subduction zones

Marie Estelle Solange Violay, Lucas Xan Pimienta

Unusually high compressional (P) to shear (S) wave velocity ratios (V-p/V-s) were measured at different subduction zones and interpreted as fluid-pressurized regions. Because no laboratory data reported such high values in isotropic rocks, mineralogical or ...

Effects of Pore and Cage Topology on the Thermodynamics of n-Alkane Adsorption at Bronsted Protons in Zeolites at High Temperature

Berend Smit

Monte Carlo simulations are used to systematically investigate the effects of structural topology on the thermodynamics of n-alkanes adsorbed at Bronsted protons in zeolites having one-dimensional channel systems. In zeolites without cages, the enthalpy an ...

We report measurements of charm-mixing parameters based on the decay-time-dependent ratio of D-0 -> K+pi(-) to D-0 -> K-pi(+) rates. The analysis uses a data sample of proton-proton collisions corresponding to an integrated luminosity of 5.0 fb(-1) recorde ...
