Energy conversion, table

Energy conversion table. Values of photon (vacuum) wavelength (nm), wavenumber (1 cm-1), frequency (THz) and energy (eV, J), as well as the energy per mole (J mol-1) of a chemical reaction can be easily converted if a ruler is placed horizontally over the chart. The bandgaps of different semiconductors are also indicated, as well as the wavelength of the intensity peak of a blackbody radiation for different temperatures.

As an example, GulnSe2 is a known low band-gap material (1.0 eV) that shows promise for use in solar energy conversion [106]. We can imagine preparing rare-earth based materials using the formulation shown in Table 14.5. 

C06-0129. Use average bond energies (see Table 6-2) to estimate the net energy change per mole of silicon for the conversion of a silicon chain into an Si—O—Si chain. Repeat this calculation to estimate the net energy change per mole of carbon for the conversion of a carbon chain into a C—O—C chain. 

One of the most important environmental criteria for the production of energy crops is the energy yield per hectare. The energy yield is mainly dependent on the biomass yield and on the conversion technology, and hence on the fraction of crop used as energy source (Table 5.11). 

Of particular practical interest are the general energy conversion factors (Lewis and Randall, 1970) presented in table A1.4.

This is the efficiency of energy conversion between mechanical and electrical forms. For PZTs, it ranges from 0.5 to 0.7, which are the most efficient of all known piezoelectric materials (see Table 9.1). For quartz, the coupling constant is about 0.1.
