Functionalization of Graphene for Efficient Energy Conversion and Storage [PDF]

open access: possibleAccounts of Chemical Research, 2012
As global energy consumption accelerates at an alarming rate, the development of clean and renewable energy conversion and storage systems has become more important than ever. Although the efficiency of energy conversion and storage devices depends on a variety of factors, their overall performance strongly relies on the structure and properties of the

The Efficiency of Energy Conversion by Swimming Muscles of Fish

1993
The efficiency of energy conversion by fish myotomal muscle undergoing sinusoidal length changes with brief periods of stimulation in each cycle has been found to be greater than the efficiency of the same type of muscle when tetanically stimulated.

Photovoltaic cell: efficiency of energy conversion

European Journal of Physics, 2000
Two additions to student experiments with a photovoltaic cell are described. The power of the incident radiation is determined experimentally and the efficiency of the energy conversion is presented as a function of the temperature of the source of irradiation, an incandescent lamp.

The maximum efficiency of the conversion of solar energy into wind energy

American Journal of Physics, 1991
In the present paper, the Gordon and Zarmi model is applied for the conversion of solar energy into wind energy, in such a way that simple calculations lead to a universal result: The upper bound for the conversion efficiency of solar energy into wind energy equals 8.3%.

A high-efficiency energy conversion system

IECEC 96. Proceedings of the 31st Intersociety Energy Conversion Engineering Conference, 2002
Introduces a fundamentally new method for converting pressure into rotative motion. An historical background is given. An idealized nonturbine Brayton cycle manometric engine and associated equations are described. Salient features are explained, together with suggested applications.

High Energy Conversion Efficiency in Nanofluidic Channels

Nano Letters, 2012
It is proposed that the layering of large ions at the wall/liquid interface of nanofluidic channels can be used to achieve high efficiency (possibly >50%) in the conversion of hydrostatic energy into electrical power. Large ions tend to produce peaks and troughs in their concentration profiles at charged walls, producing high concentrations far from ...
