[Au4(dppb)3]2+ – A Planar Gold Cluster with Bright Excitation Wavelength Dependent Emission

Small, EarlyView.
The first planar [Au4]2+ cluster with a deltoid geometry displays red to near‐infrared emission tunable from 700 to 918 nm. A quantum yield of 17% is observed at 770 nm upon 375 nm excitation. Excitation‐wavelength‐dependent shifts in emission reveal the involvement of multiple excited states, highlighting unprecedented photophysical versatility in ...

Two-dimensional cylindrical magnetosonic shock waves in a relativistic degenerated plasma

New Journal of Physics
In this paper, the characteristics of two-dimensional magnetosonic (MS) shock waves have been studied in a nonplanar relativistic degenerate collisional magnetoplasma whose constituents are non-degenerate warm ions and relativistic degenerated electrons.

Bi[IrBi6I12], Ag3[IrBi6I12], and BixCu3–3x[IrBi6I12]: Rock‐Salt Superstructures Based on Heavy‐Atom Clusters

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.

Ultra-relativistic Electron Acceleration during High-intensity Long-duration Continuous Auroral Electrojet Activity Events

The Astrophysical Journal
Magnetospheric relativistic electrons are accelerated during substorms and strong convection events that occur during high-intensity long-duration continuous auroral electrojet activity (HILDCAA) events, associated with solar wind high-speed streams ...

Teaching about the relativistic background of synchrotron radiation: some intriguing aspects with strong didactic implications

Journal of Synchrotron Radiation, EarlyView.
Explaining synchrotron radiation properties often requires using the speed of light with respect to a moving object like a detector, which may not be the invariant c. This surprising fact also leads to a rarely explored link between relativity and quantum mechanics.Not fully grasping the concepts of relativity can lead to misunderstandings about the ...

A Bayesian approach to spectroscopic depth sectioning for locating dopant atoms

Journal of Microscopy, EarlyView.
Abstract Locating dopants in 3D is of great interest as advanced materials and devices increasingly rely on control at atomic dimensions, and microscopy tools are constantly in development for this purpose. One potential tool is electron energy loss spectroscopy (EELS) depth sectioning, where a core‐loss signal is collected as a function of electron ...

Powers That Be: An Adventure in Metaphysics

Philosophical Investigations, EarlyView.
ABSTRACT This paper is an investigation into the increasingly popular trend amongst philosophers on the metaphysics of powers, exemplified by the statement: ‘To be real is to possess a power to affect (or to be affected by) other things’. First, I briefly trace the history of this idea (from the Eleatic dialectic of ancient times to present day quantum
