Speciation of Lanthanide Metal Ion Dopants in Microcrystalline All-Inorganic Halide Perovskite CsPbCl3

David Lyndon Emsley, Dominik Józef Kubicki, Daniel Prochowicz, Amita Ummadisingu, Albert Hofstetter

Lanthanides are versatile modulators of optoelectronic properties owing to their narrow optical emission spectra across the visible and near-infrared range. Their use in metal halide perovskites (MHPs) has recently gained prominence, although their fate in ...

Ionic wind amplifier for energy-efficient air propulsion: Prototype design, development, and evaluation

Julien Reymond, Amirmohammad Rajabi, Lei Xie, Donato Rubinetti

Ionic wind, produced by electrohydrodynamic (EHD) processes, holds promise for efficient airflow generation using minimal power. However, practical applications have been limited by relatively low flow rates. This study introduces a novel prototype device ...

Alpha-Nickel Hydroxide Coating of Metallic Nickel for Enhanced Alkaline Hydrogen Evolution

Yunchang Liang

In this work, alkaline hydrogen evolution reaction (HER) processes of three typical nickel-based electrocatalysts [i.e., Ni, alpha-Ni(OH)(2), and beta-Ni(OH)(2)] were investigated to probe critical factors that determine the activity and durability. The HE ...

Revealing the Surface Chemistry for CO2 Hydrogenation on Cu/CeO2–x Using Near-Ambient-Pressure X-ray Photoelectron Spectroscopy

Andreas Züttel, Emad Oveisi, Thi Ha My Pham, Wen Luo, Mo Li, Young Jun Ko

Catalytic reduction of CO2 to valuable products is an attractive route for CO2 recycling. CeO2-supported Cu catalysts have shown high activity and selectivity for the hydrogenation of CO2 to CO. To uncover the origin of their high performance, we prepared ...

Carbon dioxide activation and hydrogenation over copper-based catalysts studied by near-ambient pressure X-ray photoelectron spectroscopy

Mo Li

Carbon neutrality has been proposed as a commitment by the international communities for the well-being of human. To achieve carbon neutrality, one practical approach is to synthesize fuels and chemicals through CO2 hydrogenation to replace fossil fuels. C ...

Accessing the plus IV Oxidation State in Molecular Complexes of Praseodymium

Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic

Out of the 14 lanthanide (Ln) ions, molecular complexes of Ln(IV) were known only for cerium and more recently terbium. Here we demonstrate that the +IV oxidation state is also accessible for the large praseodymium (Pr) cation. The oxidation of the tetraki ...

Taking lanthanides out of isolation: tuning the optical properties of metal-organic frameworks

Berend Smit, Kevin Sivula, Nestor Guijarro Carratala, Kyriakos Stylianou, Gloria Capano, Andrzej Gladysiak, Christopher Patrick Ireland, Maria Fumanal Quintana, Stavroula Kampouri, Davide Tiana, Samantha Lynn Anderson

Metal organic frameworks (MOFs) are increasingly used in applications that rely on the optical and electronic properties of these materials. These applications require a fundamental understanding on how the structure of these materials, and in particular t ...

Design of Ductile Rare-Earth-Free Magnesium Alloys

William Curtin, Binglun Yin, Zhaoxuan Wu, Rasool Ahmad

Pure Mg has low ductility due to a transition of < c+a > pyramidal dislocations to a sessile basal-oriented structure. Dilute alloying generally improves ductility. Enhancement of pyramidal cross-slip from the lower-energy pyramidal II plane to the higher- ...

Characterizing crystalline defects in single Xe nanoparticles from angular correlations of single-shot diffracted X-rays

Yiming Li, Christoph Bostedt

We performed a wide-angle X-ray scattering experiment of single Xe nanoparticles using an X-ray free electron laser. We developed a novel analysis method that focuses on the angular correlation between plural Bragg spots in single-shot diffraction patterns ...

Crystal electric field excitations in the quantum spin liquid candidate NaErS2

Christian Rüegg, Daniel Biner, Shang Gao

The delafossite family of compounds with a triangular lattice of rare earth ions has been recently proposed as a candidate host for quantum spin liquid (QSL) states. To realize QSLs, the crystal electric field (CEF) ground state of the rare earth ions shou ...
