Study of backward Brillouin scattering in gas-filled anti-resonant fibers

Luc Thévenaz, Malak Mohamed Hossameldeen Omar Mohamed Galal, Li Zhang

Brillouin scattering in gas shows unmatched gain properties in hollow-core optical fibers filled at high pressure. Here, the gain characteristics are studied for two common gases, namely, N2 and CO2, which show distinct features and are compared to expecte ...

A novel interfacial polymerization assisted phase inversion process for the facile fabrication of ion-selective nanofiltration membranes

Zongyao Zhou, Tao Liu, Shijie Hu

Interfacial polymerization (IP) and non-solvent induced phase inversion (NIPS) are the two most commonly used mainstream technologies to fabricate separation membranes. Taking their advantages, we developed a simple, facile and scalable method to integrate ...

From Automated Bootstrapping to Collaborative Editing: A Framework for 4D City Reconstruction

Rémi Guillaume Petitpierre, Paul Robert Guhennec, Beatrice Vaienti, Didier Louis Dupertuis

We propose a framework for the construction of 4D scientific models for cities of the past. It leverages both the use of computational methods for bootstrapping, and a collaborative interface for visualisation and edition. This permits to continuously enri ...

Two-dimensional Material Membranes for Gas Separation

Mostapha Dakhchoune

Two-dimensional (2D) materials with atom- or few-atoms-thick layers have emerged as building-blocks in the synthesis of the next-generation membrane-based separations. Generally, 2D material-based membranes display high permeation and high selectivity due ...

High Influence of Potassium Bromide on Thermal Decomposition of Ammonia Borane

Andreas Züttel

The present paper presents a thorough experimental investigation of mechanistic pathways of thermal decomposition of ammonia borane (AB) and its mixture with KBr. A comparative detection and temperature-dependent in situ monitoring of the decomposition pro ...

Correction factors to apply to fission rates measured by miniature fission chambers in various neutron spectra

Vincent Pierre Lamirand

CEA develops and makes use of miniature fission chambers (MFCs, with radius down to 1.5 mm) for reactor physics conducted in experimental reactors such as EOLE and MINERVE zero power reactors (CEA Cadarache). When measuring fission rate, it is known that t ...

Influence of Mass-Transfer Limitations on Carbon Isotope Fractionation during Microbial Dechlorination of Trichloroethene

Christof Holliger

Mass transfer of organic contaminants from nonaqueous phase liquids to the aqueous phase can significantly modulate the observable carbon isotope fractionation behavior associated with contaminant transformation. We evaluated the effects of kinetic interph ...

The Light at the End of the Tunnel Junction - Improving the Energy Resolution of UV Single-Photon Spectrometers using Diffusion Engineering

Andreea Veronica Savu

We present experimental results which test whether diffusion engineering can increase the energy resolution of a single-photon superconducting tunnel-junction spectrometer. When a UV photon is absorbed in superconducting Al, it creates an excess number of ...

Validation of axial pin power distributions in a 1010 BWR assembly across an enrichment boundary under full-density water moderation conditions

Rakesh Chawla, Fabian Jatuff, Flavio Dante Giust

Critical experiments involving fuel pin gamma-scans have been performed to characterise total fission reaction rate axial distributions in a Westinghouse SVEA-96+ assembly under full-density water moderation [these investigations are part of the co-operati ...

Neutronics investigations for the lower part of a westinghouse SVEA-96+ assembly

Rakesh Chawla, Fabian Jatuff, André Meister

Accurate critical experiments have been performed for the validation of total fission (Ftot) and 238U-capture (C8) reaction rate distributions obtained with CASMO-4, HELIOS, BOXER, and MCNP4B for the lower axial region of a real Westinghouse SVEA-96 + fuel ...
