Klaus-D. Hüllemannitions in the coal react with hydrogen during liquefaction. A hydrogenation index (HI) and exchange index (EI) were formulated to measure the amount of deuterium incorporated due to hydrogenation and exchange reactions, respectively. In the coal-deuterium system, deuterium incorporation was found to

Klaus-D. Hüllemann it is converted into heat, a form of energy. Energy must therefore have arrived from the sun across this immense distance. In fact almost all the energy known to man has been derived from the sun either now or in past ages. Thus the sun’s energy, which millions of years ago was responsible for the

Klaus-D. Hüllemannh can be applied to all kinds of supporting substrates independent of their conductivity. First, we find that due to the Smoluchowski effect a localized electrostatic dipole moment is present at the end of metallic tips. Since its positive pole points towards the surface, we are able to identify the
