Interpretation of solar type III radio emission

open access: yesThe Astrophysical Journal, 1983
It is proposed that the induced bremsstrahlung can account for the type III solar radio emission. Our theory can successfully explain the recent astrophysical observations.

Unveiling Aggregation‐Induced Singlet Fission in Push–Pull Diketopyrrolopyrrole Water Dispersed Nanoaggregates and Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Aggregates of diketopyrrolopyrrole dipolar and quadrupolar systems exhibit panchromatic absorption spectra extending in the entire visible range. Upon aggregation in water and in the solid state, their fluorescence is almost completely quenched and their singlet excited state lifetime is significantly shortened.

Thermoplasmonic Nanorings for Passive Solar‐Responsive Smart Windows in Energy‐Efficient Building Applications

open access: yesAdvanced Functional Materials, EarlyView.
This work presents scalable silver nanorings with tunable thermoplasmonic properties for smart window applications. By responding to sunlight and environmental changes, the nanorings modulate near‐infrared light and reduce heat transmission. Their unique geometry enables dynamic optical control, offering a promising route toward energy‐efficient ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Direct evidence for solar wind control of Jupiter's hectometer-wavelength radio emission [PDF]

open access: yes
Observations of the solar wind close to Jupiter, by the Voyager 1 and Voyager 2 spacecraft in 1978 and 1979, are compared with the hectometer wavelength radio emission from the planet. A significant positive correlation is found between variations in the

Velocity profiles of interplanetary shocks [PDF]

open access: yes, 1983
The type 2 radio burst was identified as a shock propagating through solar corona. Radio emission from shocks travelling through the interplanetary (IP) medium was observed.

Integrative Approaches for DNA Sequence‐Controlled Functional Materials

open access: yesAdvanced Functional Materials, EarlyView.
DNA is emerging as a programmable building block for functional materials with applications in biomimicry, biochemical, and mechanical information processing. The integration of simulations, experiments, and machine learning is explored as a means to bridge DNA sequences with macroscopic material properties, highlighting current advances and providing ...

ON VARIABILITY OF OBSERVED POLARIZATION PARAMETERS OF GALACTIC RADIO EMISSION AT METER WAVES

open access: yesOdessa Astronomical Publications, 2017
The polarization temperature Tp variations, which exceeded errors of measurements were observed already during the initial (1958-1962) and then the following measurements of linear polarization of galactic radio emission at meter waves.

Warm Dust and Spatially Variable PAH Emission in the Dwarf Starburst Galaxy NGC 1705

open access: yes, 2006
We present Spitzer observations of the dwarf starburst galaxy NGC 1705 obtained as part of SINGS. The galaxy morphology is very different shortward and longward of ~5 microns: short-wavelength imaging shows an underlying red stellar population, with the ...
