Phase stabilization of all-inorganic perovskite materials for photovoltaics

Ulf Anders Hagfeldt, Wanchun Xiang

Cubic phase stabilization is extremely important for the application of cesium lead halide inorganic perovskite materials into fabrication of perovskite solar cells. Methods on how to stabilize inorganic perovskite phase have been discussed in this review. ...

Cubic zirconia in >2370◦C impact melt records Earth’s hottest crust

Cyril Cayron

Bolide impacts influence primordial evolution of planetary bodies because they can cause instantaneous melting and vaporization of both crust and impactors. Temperatures reached by impact-generated silicate melts are unknown because meteorite impacts are e ...

Structure of a model TiO2 photocatalytic interface

Gabriele Tocci

The interaction of water with TiO2 is crucial to many of its practical applications, including photocatalytic water splitting. Following the first demonstration of this phenomenon 40 years ago there have been numerous studies of the rutile single-crystal T ...

Computational Characterization of the Dependence of Halide Perovskite Effective Masses on Chemical Composition and Structure

Michael Graetzel, Ursula Röthlisberger, Simone Meloni, Amir Hesam Salavati, Giulia Palermo, Negar Ashari Astani

Effective masses are calculated for a large variety of perovskites of the form ABX(3) differing in chemical composition (A= Na, Li, Cs; B = Pb, Sn; X= Cl, Br, I) and crystal structure. In addition, the effects of some defects and dopants are assessed. We s ...

Selecting the best AOP for isoxazolyl penicillins degradation as a function of water characteristics: Effects of pH, chemical nature of additives and pollutant concentration

César Pulgarin, Paola Villegas Guzman

To provide new insights toward the selection of the most suitable AOP for isoxazolyl penicillins elimination, the degradation of dicloxacillin, a isoxazolyl penicillin model, was studied using different advanced oxidation processes (AOPs): ultrasound (US), ...

Nanoionics Phenomena and Devices with Oxide Thin Films

Mahmoud Hadad

The number of studies on solid state ionic thin films (Nanoionics) has increased dramatically over last decades due to their high potential in micro and nanoscale technologies. Micro solid oxide fuel cells (micro-SOFC), and resistive switching memories (Re ...

Thermal spin torques in magnetic insulators

Jean-Philippe Ansermet, Sylvain Bréchet, Ping Che, Haiming Yu, Yi Zhang, Sa Tu, Cheng Zhao, Francesco Antonio Vetrò, Yao Zhang

The damping of spin waves transmitted through a two-port magnonic device implemented on a yttrium iron garnet thin film is shown to be proportional to the temperature gradient imposed on the device. The sign of the damping depends on the relative orientati ...

Applications Of Mechanical Spectroscopy To Industrial Materials

Robert Schaller

The paper is a review of original results, which were obtained by mechanical spectroscopy in the development of industrial materials, such as grey cast iron (damping capacity), aluminum alloys (recrystallization), nickel alloys (grain boundary embrittlemen ...

Determination of Thermal Expansion Coefficients and Locating the Temperature-Induced Phase Transition in Methylammonium Lead Perovskites Using X-ray Diffraction

Ulf Anders Hagfeldt, Tor Jesper Jacobsson

Lead halogen perovskites, and particularly methylammonium lead iodine, CH3NH3PbI3, have recently attracted considerable interest as alternative solar cell materials, and record solar cell efficiencies have now surpassed 20%. Concerns have, however, been ra ...

A new class of chiral materials hosting magnetic skyrmions beyond room temperature

Henrik Moodysson Rønnow, Jonathan White

Skyrmions, topologically protected vortex-like nanometric spin textures in magnets, have been attracting increasing attention for emergent electromagnetic responses and possible technological applications for spintronics. In particular, metallic magnets wi ...

Characterization of Cracks and their Effects on the Effective Transport Pathways in Ni-YSZ Anodes after Reoxidation Using X-Ray Nanotomography

Jan Van Herle, Jian Wang, Siyuan Wang, Arata Nakajo, Fabio Greco

Reduction-oxidation cycling of Ni-based electrodes for solid oxide fuel/electrolysis cells irreversibly alters their microstructure and can cause the fracture of the electrolyte. Non-destructive 3-D imaging enables tracking of microstructural changes that ...
