On the Snow Line in Dusty Protoplanetary Disks [PDF]

open access: yes, 1999
The snow line, in Hayashi's (1981) model, is where the temperature of a black body that absorbed direct sunlight and re-radiated as much as it absorbed, would be 170~K. It is usually assumed that the cores of the giant planets, e.g., Jupiter, form beyond

All-day passive radiative cooling using common salts

open access: yesMaterials Horizons, 2023
Radiative cooling materials continue to underperform compared to their theoretical potential due to parasitic heating from contact with ambient air. Solutions to this problem are expensive or complex to fabricate. Here, a potentially inexpensive, simply fabricated material that improves cooling performance by reducing parasitic heating was created ...

Disordered metamaterial coating for daytime passive radiative cooling [PDF]

open access: yesAIP Advances, 2021
In this theoretical study, a disordered metamaterial coating with randomly embedded TiO2 dielectric microspheres in a polydimethylsiloxane matrix has been designed for the purpose of daytime passive radiative cooling. While retaining the necessary optical properties of high reflectivity (≈94%) in the solar spectrum and high emissivity (≈96%) in the ...

Entropy Injection as a Global Feedback Mechanism [PDF]

open access: yes, 2002
Both preheating of the intergalactic medium and radiative cooling of low entropy gas have been proposed to explain the deviation from self-similarity in the cluster L_x-T_x relation and the observed entropy floor in these systems.

Research on the performance of radiative cooling and solar heating coupling module to direct control indoor temperature [PDF]

open access: yes, 2020
The energy crisis and environmental pollution pose great challenges to human development. Traditional vapor-compression cooling consumes abundant energy and leads to a series of environmental problems.

Passive radiative "thermostat" enabled by phase-change photonic nanostructures

open access: yes, 2018
A thermostat senses the temperature of a physical system and switches heating or cooling devices on or off, regulating the flow of heat to maintain the system's temperature near a desired setpoint.

Generalized bioinspired approach to a daytime radiative cooling "skin"

open access: yes, 2020
Energy-saving cooling materials with strong operability are desirable towards sustainable thermal management. Inspired by the cooperative thermo-optical effect in fur of polar bear, we develop a flexible and reusable cooling skin via laminating a ...

Simulating Electron Transport and Synchrotron Emission in Radio Galaxies: Shock Acceleration and Synchrotron Aging in Three-Dimensional Flows [PDF]

open access: yes, 2001
We present the first three-dimensional MHD radio galaxy simulations that explicitly model transport of relativistic electrons, including diffusive acceleration at shocks as well as radiative and adiabatic cooling in smooth flows.

Spiral waves triggered by shadows in transition disks [PDF]

open access: yes, 2016
Circumstellar asymmetries such as central warps have recently been shown to cast shadows on outer disks. We investigate the hydrodynamical consequences of such variable illumination on the outer regions of a transition disk, and the development of spiral
