Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

The local conservation law for energy in classical general relativity is subtle and has been extensively discussed. We propose a new physical interpretation for this law which naturally brings out a thermodynamic flavor of general relativity theory. Given a reference system, we are able to rewrite the local conservation law so that it separates into ...

The problem of temperature regulation is most acute for the astronaut when he is outside his vehicle and therefore disconnected from the relatively bulky machinery which normally attends to his thermal needs. It is necessary to arrange that metabolic heat is transported from the skin surface to some device which will absorb it.

The Demand for Space Heating Energy
The Review of Economics and Statistics, 1975PREVIOUS studies of residential and commercial energy use, exclusive of electricity, have generally found that price is not a significant determinant of demand.' This paper analyzes the demand for space heating energy using cross-sectional data by state for 1971.

The heat equation on a matrix space
Journal of Mathematical Sciences, 2007One of examples of a parametric family of continuous on the \(n\)-dimensional Euclidean space functions (the Dirac family) is a so-called heat source (in other words, a kernel of thermal conductivity), which satisfies a nonlinear heat equation of a special structure.

Thermoelectric Heat Pumps for Space Heating
1984The reported work on thermoelectrical heat pumps has been conducted on extracted air/water pumps for space heating. It includes: the analysis of fabrication conditions of large thermoelectric pellets, the dimensioning of heat pumps with a computer program, design, fabrication and test of a vertical column with 34 pellets, design ...

Absorption Heat Pumps for Space Heating
1984Absorption resorption cycles with non toxic, inexpensive and non flamable fluids are investigated to be used in heat pumps for space heating. CO2 is a good fluid because of its properties. An exhaustive list of solvents has been drawn up. A test loop has been built and experiments are running.
