Microscopic Origin of Temperature‐Dependent Anisotropic Heat Transport in Ultrawide‐Bandgap Rutile GeO2

open access: yesAdvanced Functional Materials, EarlyView.
Rutile GeO2${\rm GeO}_{2}$ exhibits orientation‐dependent heat transport with temperature‐dependent anisotropy, showing higher cross‐plane thermal conductivity along [001] than along the equivalent in‐plane [100] and [010] directions. Temperature‐dependent TDTR measurements and first‐principles phonon calculations identify the microscopic phonon ...

Caloric theory: beginning of its end

2020
Abstract The early 1800s provided new evidence challenging the caloric theory when Rumford bored a cannon and boiled water, Davy melted ice by using friction, and Young made the connection between light and radiant heat. Mayer and Joule then succeeded in killing caloric by simply ignoring it and instead embracing work–heat equivalence.

Phenomenological approach to the caloric theory of heat

Thermochimica Acta, 2008
Abstract This contribution presents an alternative approach to thermal physics and to its affiliated thermodynamics aiming to initiate a discussion concerning the related problems of its fundamental nature. We reason that the classical thermodynamics suffers considerably from a misinterpretation of experimental facts known as the Principle of ...

Theory of giant-caloric effects in multiferroic materials

Journal Physics D: Applied Physics, 2013
A generalized thermodynamic theory of giant-caloric effects in coupled multiferroic solids is introduced. The generalized theory allows analytical derivation of any caloric effect in solids displaying any type of cross coupling. In the particular cases of the non-coupled ferroic materials, the theory reproduces the well-known formulae describing ...

CAN EXPERIMENTS ON CALORIC RESTRICTION BE RECONCILED WITH THE DISPOSABLE SOMA THEORY FOR THE EVOLUTION OF SENESCENCE?

Evolution; International Journal of Organic Evolution, 2001
A publication by Shanley and Kirkwood (2000) attempts to explain data on caloric restriction (CR) and life extension in the context of the Disposable Soma (DS) theory for the evolution of senescence. As the authors concede, this juxtaposition appears at first to offend intuition: According to the DS theory, senescence is the result of a tight budget ...

Lavoisier and the Caloric Theory

The British Journal for the History of Science, 1972
Professional historians of science generally recognize the importance of Lavoisier's theory of heat. However, it commonly receives scant attention in the historical treatment of his chemical theories except perhaps as an example illustrating his conservatism and giving the impression that the caloric theory, although perhaps important in the ...

An Atomic Theory of the Magneto-Caloric Effect

Nature, 1936
As a result of an investigation on the change of temperature with magnetisation, Mr. T. Okamura has succeeded in separating the reversible and irreversible thermal effects. He has shown that the irreversible temperature variation agrees satisfactorily with the Honda-Okubo theory of ferromagnetism1.
