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

open access: yesGeofísica 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.

Structure of the Solar Atmosphere: A Radio Perspective

open access: yesFrontiers in Astronomy and Space Sciences, 2020
Solar radio emission has been providing information about the Sun for over half a century. In order to fully exploit this information, one needs to have a broader view of the solar atmosphere, which cannot be provided by radio observations alone.

Multiwave Siberian Radioheliograph

open access: yesSolar-Terrestrial Physics, 2020
The article discusses characteristics, fundamental and applied tasks of the Siberian Radioheliograph that is developed at the ISTP SB RAS Radio Astrophysical Observatory and spectropolarimetric complex that measures the total flux of solar radio emission.

Latest results on Jovian disk X-rays from XMM-Newton [PDF]

open access: yes, 2007
We present the results of a spectral study of the soft X-ray emission (0.2–2.5 keV) from low-latitude (‘disk’) regions of Jupiter. The data were obtained during two observing campaigns with XMM-Newton in April and November 2003.

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

open access: yesAdvanced Functional Materials, EarlyView.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Periodicities in Solar Radio Noise Emission [PDF]

open access: yesAustralian 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.

Halide Composition Controls Phase Morphology and Device Specific Performance in Perovskite Photovoltaics and Light Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

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

open access: yesThe 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.

High‐Performance, Air‐Stable and Eco‐Friendly Terpene‐Processed Organic Solar Cells via Solvent‐Composition‐Controlled Film Formation Kinetics

open access: yesAdvanced Functional Materials, EarlyView.
Solvent‐composition‐controlled film formation enables high‐performance (efficiency = 18.66%) and air‐stable terpene‐processed organic solar cells. An optimized eucalyptol/tetralin ratio of 50:50 (v/v) balances molecular solvation and aggregation kinetics, producing favorable nanoscale phase separation and vertical composition gradients.
