Energy, conversion factors

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

Other workers have employed different sensitiser systems, e.g. duel sensitisation by a zinc porphyrin and copper phthalocyanine on TiOj, Eosin Y or tetrabro-mophenol blue on ZnO, and a ZnO/SnOj mixture with a ruthenium bipyridyl complex, to produce good energy conversion factors. 

Whilst producing energy conversion factors comparable with semi-conducting photovoltaics, the original Gratzel type DSSCs do suffer from some problems around the use of liquid electrolytes. These problems include the need for highly efficient...

More accurate values for the constants and energy conversion factors are given inside the back cover of this book. 

The present third edition has been substantially revised and extended with new sections (e.g. on uncertainty) compared to the second edition. The most accurate recent fundamental physical constants and atomic masses are tabulated. The symbol as well as the subject index has been extended considerably to facilitate the usage of the Green Book. A table of numerical energy conversion factors is given and the most recent lUPAC periodic table of the elements is given on the inside back cover. 

In this text, the symbols H+ and e generally used by chemists are adopted as symbols for the proton and electron, rather than p and e, respectively, as recommended by IUPAC. The symbol e represents the elementary charge the charge of the electron is c, that of the proton is e. In chemical schemes these charges will be represented by and 0, respectively. Some fundamental physical quantities and energy conversion factors are given in Tables 8.1 and 8.2.

In summary, if you can do all your work in SI, you need never be concerned about force-mass conversions (N = kg m/s ) or energy conversions (J = N-m=W s). If you are confronted with problems (or literature, or current U.S. legal definitions) involving the kgf, Ibf, cal, kcal, or Btu, you must follow the rules outlined above Always write down the dimensions, treat the dimensions as algebraic quantities, and multiply by 1 as often as needed to get the quantities into the desired set of units, using the appropriate values of the force-mass conversion factor and the thermal-mechanical energy conversion factor. Even in SI, if you stray from the basic units (m, kg, s, A, K, mol, and cd), you will need conversion factors such as...
