We study the radiative heat flux between two nanoparticles in close vicinity to natural hyperbolic material hBN with its optical axis oriented parallel interface. show that can be efficiently modulated when rotating due coupling highly directional surface modes hBN. Finally, we discuss thickness and distance dependence of this effect.

Passive radiative cooling is currently the frontier technology in renewable-energy research. In terms of extraterrestrial applications, a critical component to thermal management system spacecraft, where extreme environment space can cause large temperature variations that break and damage equipment. For terrestrial nocturnal or daytime expected lead cost-effective passive heat without need ine...

Using recently calculated analytic and numerical models for the thermal structure of ultramagnetized neutron stars, we estimate the effects that ultrastrong magnetic fields B ≥ 10 G have on the thermal evolution of a neutron star. Understanding this evolution is necessary to interpret models that invoke “magnetars” to account for soft γ-ray emission from some repeating sources. Subject headings...

In this paper, we explore the far-field radiative thermal rectification potential of common materials such as metals,ceramics and doped semi-conductors using thermo-radiative properties extracted from literature. Seventeen different are considered. The coefficient is then calculated for 136 pairs materials; each pair can be used two terminals a diode. A bias 200 K choice value only bound by dat...

During the past two decades, there have been tremendous developments in near-field imaging and local probing techniques. Examples are the Scanning Tunneling Microscope (STM), Atomic Force Microscope (AFM), Near-field Scanning Optical Microscope (NSOM), Photon Scanning Tunneling Microscope (PSTM), and Scanning Thermal Microscope (SThM).Results showed that the average reflectance for a dopant con...

The present paper focuses on numerical study for an inclined magneto-hydrodynamic effect on free convection flow of a tangent hyperbolic nanofluid embedded with Carbon nanotubes (CNTs) over a stretching surface taking velocity and thermal slip into account. Two types of nanoparticles are considered for the study; they are single and multi-walled nanotubes. The presentation of single-parameter g...
