Advanced Materials, EarlyView.A novel one‐shot integration electropolymerization (OSIEP) method is developed as a breakthrough on the intricate photolithographic steps, enabling to compress all processes from synthesis to channel integration in one‐shot manufacturing. The specially designed dual bipolar electrodes provide the targeted depositions of poly(3,4‐ethylenedioxythiophene)

Contemporary Physics, 2007
The radiation emitted by a heated body is generally quoted as a typical example of incoherent radiation, in distinction to laser radiation. One is nearly isotropic, the other highly directional; one is spectrally broad, the other quasi-monochromatic. It may come as a surprise that the thermal radiation of a large number of substances is coherent, both ...

A Thermal Diode Based on Nanoscale Thermal Radiation
ACS Nano, 2018In this work we demonstrate thermal rectification at the nanoscale between doped Si and VO2 surfaces. Specifically, we show that the metal-insulator transition of VO2 makes it possible to achieve large differences in the heat flow between Si and VO2 when the direction of the temperature gradient is reversed.

Paradoxes of thermal radiation
European Journal of Physics, 2009This paper presents an analysis of the thermal behaviour of objects exposed to a solar-type flux of thermal radiation. It aims to clarify certain apparent inconsistencies between theory and observation, and to give a detailed exposition of some critical points that physics textbooks usually treat in an insufficient or incorrect way.

Publisher Summary This chapter explores the phenomena of thermal radiation. Radiation is a mechanism that may take place in the absence of matter. At high temperatures, radiation is often the dominant mechanism of heat transfer and thus, it is important that one is able to accurately calculate radiant energy transport rates if he/she is to design high

Fundamentals of Thermal Radiation [PDF]
, 2020 This chapter contains an introduction to the electromagnetic wave theory, blackbody radiation, plane wave reflection, and refraction at the boundary between two semi-infinite media, evanescent waves and total internal reflection, and various models used to study the optical properties of different materials.

This chapter introduces the basic physics of thermal (IR) radiation as it relates to the analysis of IR thermography and solving the challenging emissivity problem. The possible use of dual-band IR thermography is discussed. The influence of atmosphere absorption and spurious reflected radiation on the results of TNDT is discussed.

Abstract It is possible to describe thermal radiation environment at a point in space using the concept of the radiation field. This paper derives the fundamental parameters of the field, and describes how they may be measured. The use of the radiation vector, or its equivalent the vector radiant temperature, is recommended as a measure of the ...

All bodies emit radiation to their surroundings through electromagnetic waves due to the conversion of the internal energy of the body into radiation. Reflectivity, absorptivity, and transmissivity of bodies are defined. Planck’s law for spectral distribution of emissive power of a blackbody is presented in Sect.

Responses of the Rat to Thermal Radiation
American Journal of Physiology-Legacy Content, 1957Using the method of rapid measurement of skin temperature during exposure to known amounts of thermal radiation, the ‘thermal inertia’ or kpc product ( k = thermal conductivity, p = density, c = specific heat) was measured for the rat skin. An average kpc value of 84 ± 18 x 10–5 cal2/cm4/sec/°C2 was obtained for the lightly anesthetized animal.
