IS⊙IS Solar γ-Ray Measurements: Initial Observations and Calibrations

The Astrophysical Journal
High-energy neutral solar radiation in the form of γ -rays and neutrons is produced as secondary products in solar flares. The characteristics of this emission can provide key information regarding the energization of charged particles, particularly when

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

Advanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Instabilities, Wave Emission, and Energy Transport along Bursty Bulk Flows and Supra-arcade Downflows: Differences, Similarities, and Effects on the Surrounding Regions

The Astrophysical Journal
We examine the stability conditions for two posteruptive phenomena in the solar–terrestrial environment, namely, bursty bulk flows (BBFs) in the Earth’s magnetotail and supra-arcade downflows (SADs) in the solar corona.

Soft X-ray emissions, meter-wavelength radio bursts, and particle acceleration in solar flares

The Astrophysical Journal, 1988
A detailed study of the relationship between metric radio bursts and soft X-ray flares has been made using an extensive data set covering 15 yr. It is found that type IV emission is mainly associated with long-duration 1-8 A events that are known to be well associated with coronal mass ejections.

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

Advanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

Spectral Evolution of Mildly Relativistic Electrons in Solar Flares

The Astrophysical Journal
Solar flares are a powerful engine capable of accelerating ambient plasma particles to high nonthermal energies. A key characteristic of these particles is their energy spectrum.
