Methylammonium Lead Iodide for Efficient X-ray Energy Conversion

László Forró, Endre Horvath, Bálint Náfrádi

We report on photocurrent generation by X-ray irradiation in methylammonium lead iodide CH3NH3PbI3 single crystals. We observed 75% of charge collection efficiency in millimeter sized samples. This efficiency is partially due to the high photon absorption ...

KEu(MoO4)(2): Polymorphism, Structures, and Luminescent Properties

Alla Arakcheeva, Philip Pattison

In this paper, with the example of two different polymorphs of KEu(MoO4)(2), the influence of the ordering of the A-cations on the luminescent properties in scheelite related compounds (A',A '') (B',B '')O-4 is investigated. The polymorphs were synthe ...

Combined Optical Coherence and Fluorescence Microscopy to assess dynamics and specificity of pancreatic beta-cell tracers

Theo Lasser, Christophe Pache, Anne Grapin-Botton, Arno Pino Bouwens, Daniel Pawel Szlag, Corinne Berclaz, Antonio Lopez

The identification of a beta-cell tracer is a major quest in diabetes research. However, since MRI, PET and SPECT cannot resolve individual islets, optical techniques are required to assess the specificity of these tracers. We propose to combine Optical Co ...

Structural and Functional Imaging of Pancreatic Islets using Optical Coherence Microscopy

Corinne Berclaz

In diabetes, pancreatic beta-cells play a key role. These cells are organized within structures called islets of Langerhans inside the pancreas and produce insulin. Insulin is one of the main hormones contributing to glucose homeostasis, which is the hallm ...

Search for B+ -> e(+)nu(e) and B+ -> mu(+)nu(mu) decays using hadronic tagging

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Jun Yong Kim, Ji Hyun Kim, Donghyun Kim, Dipanwita Dutta, Xiao Wang

We present a search for the rare leptonic decays B+ -> e(+)nu(e) and B+ -> mu(+) nu(mu) using the full Upsilon(4S) data sample of 772 x 10(6) B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. One of the ...

The negative triangularity tokamak: stability limits and prospects as a fusion energy system

Olivier Sauter, Ambrogio Fasoli, Laurent Villard, Andrei Martynov

The paper discusses edge stability, beta limits and power handling issues for negative triangularity tokamaks. The edge magnetohydrodynamic stability is the most crucial item for power handling. For the case of negative triangularity the edge stability pic ...

How non-adiabatic passing electron layers of linear microinstabilities affect turbulent transport

Laurent Villard, Stephan Brunner, Julien Stanislas Pierre Dominski

The response of passing electrons in ion temperature gradient and trapped electron mode microturbulence regimes is investigated in tokamak geometry making use of the flux-tube version of the gyrokinetic code GENE. Results are obtained using two different e ...
