Data-Driven Predictive Models: Calculational Bias in Characterization of Spent Nuclear Fuel

Ahmed Salaheldin Ahmed Shama

Characteristics of the spent nuclear fuel (SNF) are typically calculated, requiring validation a priori. The validation process relies on the difference between calculations and measurements, namely the bias. Usually, predicting the bias based on benchmark ...

Competitive Dehydrogenation and Backbone Fragmentation of Superhydrogenated PAHs: A Laboratory Study

Eduardo Carrascosa Casado

Superhydrogenated polycyclic aromatic hydrocarbons (PAHs) have been suggested to catalyze the formation of H-2 in certain regions of space, but it remains unclear under which circumstances this mechanism is viable given the reduced carbon backbone stabilit ...

Treatment of the implicit effect in Shark-X

Mathieu Hursin, Hakim Ferroukhi

Shark-X is a set of Perl-based tools build around the deterministic neutron transport code CASMO-5, used to perform uncertainty quantification for lattice calculations at the Paul Scherrer Institut (PSI). While perturbing an input parameter, e.g. a cross s ...

Role of JETPEAK database in validation of synthetic neutron camera diagnostics and ASCOT- AFSI fast particle and fusion product calculation chain in JET

Henri Weisen

JETPEAK is a comprehensive stationary-state database and a work environment for JET diagnostics data, processed data and simulations suitable for a wide variety of analytical tasks. It enables systematic modelling and efficient interpretation of synthetic ...

Tuning electronic correlations in transition metal pnictides: Chemistry beyond the valence count

Joël Mesot, Thorsten Schmitt

The effects of electron-electron correlations on the low-energy electronic structure and their relationship with unconventional superconductivity are central aspects in the research on iron-based pnictide superconductors. Here we use soft x-ray angle-resol ...

Broadband extreme ultraviolet probing of transient gratings in vanadium dioxide

Jakob Grilj

Nonlinear spectroscopy in the extreme ultraviolet (EUV) and soft x-ray spectral range offers the opportunity for element selective probing of ultrafast dynamics using core-valence transitions (Mukamel et al., Acc. Chem. Res. 42, 553 (2009)). We demonstrate ...

Quantitative separation of monomeric U(IV) from UO2 in products of U(VI) reduction

Rizlan Bernier-Latmani, Daniel Scott Alessi, Elena Suvorova Buffat, Harish Veeramani, Benjamin Uster

The reduction of soluble hexavalent uranium to tetravalent uranium can be catalyzed by bacteria and minerals. The end-product of this reduction is often the mineral uraninite, which was long assumed to be the only product of U(VI) reduction. However, recen ...

Exploring the potential of europium(III) luminescence for the detection of phase transitions in ionic liquid crystals

Jean-Claude Bünzli, Anne-Sophie Chauvin, Frédéric Gumy

The ionic liquid crystal [C12-mim]Cl has been doped with 5 mol% europium nitrate and the photophysical properties of both the ionic liquid and the trivalent europium ion have been monitored with respect to temperature in the range of 248 to +120 uC. The re ...
