Radio bursts of very short duration: Fine structure of solar flare emissions [PDF]

Geofísica Internacional, 2006
The fine time structure of sub-second radio events of solar flare emissions is described on the multichannel polarimeter of Station Basovizza at 237, 327, and 408 MHz frequencies.

A new approach to the maser emission in the solar corona [PDF]

, 2015
Aims. The electron plasma frequency ωpe and electron gyrofrequency Ωe are two parameters that allow us to describe the properties of a plasma and to constrain the physical phenomena at play, for instance, whether a maser instability develops.

Initial results of Husafell solar radio spectrograph [PDF]

, 2006
P(論文)Observing the moon surface and subsurface materials using various radio frequencies is very important for investigating the physical properties of the moon. In particular, the frequency dependence of the dielectric constant of surface and subsurface

Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots

Advanced Functional Materials, EarlyView.
CsPbX3${\rm CsPbX}_3$ lead halide perovskite quantum dots (QDs) are synthesized in a room‐temperature, five‐minute synthesis, yielding size‐controlled QDs with bright, tunable emission governed by reaction conditions and halide composition. A strongly binding ligand, OD‐PEA, ensures months‐long stability under ambient conditions and facilitates their ...

Detection of Radio Emission from Superflaring Solar-type Stars in the VLA Sky Survey

The Astrophysical Journal
Solar-type stars have been observed to flare at optical wavelengths with energies much higher than is observed for the Sun. To date, no counterparts have been observed at longer wavelengths.

Periodicities in Solar Radio Noise Emission [PDF]

Australian Journal of Physics, 1959
In a recent article, Roberts (1958) described solar radio wave emissions in the range 40-80 Mc/s. The investigations were a continuation of work initiated earlier by Wild and McCready (1950) on the dynamic radio-frequency spectrum, and by Wild, Murray, and Rowe (1954) employing a 40-240 Mc/s spectrograph.

Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
Indene‐C60 bisadduct (ICBA) accumulates at the buried interface of inverted tin‐lead perovskite solar cells, limiting undesired electron extraction while maintaining efficient hole transport. ICBA simultaneously scavenges molecular iodine, mitigating Sn2+ oxidation and interfacial recombination. This coupled electronic‐chemical regulation delivers 22.7%

Constraining Solar Emission Radius at 42 MHz During the 2024 Total Solar Eclipse Using a Student-commissioned Radio Telescope

The Astrophysical Journal
Low-frequency solar radio emission is sourced in the solar corona, with sub-100 MHz radio emission largely originating from the ∼10 ^5 K plasma around 2 optical radii.
