A Comparison between the GPM Dual-Frequency Precipitation Radar and Ground-Based Radar Precipitation Rate Estimates in the Swiss Alps and Plateau

Alexis Berne, Peter James Speirs, Marco Gabella

The Global Precipitation Measurement (GPM) mission Dual-Frequency Precipitation Radar (DPR) provides a unique set of three-dimensional radar precipitation estimates across much of the globe. Both terrain and climatic conditions can have a strong influence ...

Structure of precipitates and orientation relationships in Al, Ge, Mo-doped higher manganese silicide crystals

Philippe Buffat, Marco Cantoni, Elena Suvorova Buffat

The structure of Al, Ge, Mo-doped Higher Manganese Silicide (HMS) crystals with the general formulas Mn(Si0.99Ge0.01)(1.75), Mn(Si0.995Ge0.005)(1.75) and (Mn0.98Mo0.02)(Si0.98Ge0.02)(1.75)Al-0.01 was investigated by scanning and transmission electr ...

Ab initio Modelling of the Early Stages of Precipitation in Al-6000 Alloys

William Curtin, Michele Ceriotti, Till Junge, Daniele Giofré

Age hardening induced by the formation of (semi)-coherent precipitate phases is crucial for the processing and final properties of the widely used Al-6000 alloys. Early stages of precipitation are particularly important from the fundamental and technologic ...

Solute strengthening in random alloys

William Curtin, Céline Varvenne, Maryam Ghazisaeidi

Random solid solution alloys are a broad class of materials that are used across the entire spectrum of engineering metals, whether as stand-alone materials (e.g. Al-57xxx alloys) or as the matrix in precipitate strengthening materials (e.g. Ni-based super ...

Phase Segregation in Cs-, Rb- and K-Doped Mixed-Cation (MA)(x)(FA)(1-x)Pbl(3) Hybrid Perovskites from Solid-State NMR

Michael Graetzel, Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Daniel Prochowicz, Dominik Józef Kubicki, Albert Hofstetter

Hybrid (organic-inorganic) multication lead halide perovskites hold promise for a new generation of easily processable solar cells. Best performing compositions to date are multiple-cation solid alloys of formamidinium (FA), methylammonium (MA), cesium, an ...

Microalloying for the controllable delay of precipitate formation in metal alloys

William Curtin, Michael Frederick Francis

A model is presented to predict the effectiveness of dilute solutes in delaying precipitate formation, with application to natural and artificial aging in metal alloys. Control of aging is achieved via the binding, at natural aging temperatures, and releas ...
