These widely spaced levels inhibit equal partition of heat energy into rotational motion in hydrogen at low temperatures. The was a notorious example of hydrogen combustion and the cause is still debated. A detailed study showed that the Web of Science has strong coverage of journal publications, but poor coverage of high impact conferences. Many physical and chemical properties of hydrogen depend on the ratio it often takes days or weeks at a given temperature to reach the equilibrium ratio, for which the data is usually given. In the for the , hydrogen is generated from natural gas.

Principles of Modern Chemistry 5th ed. Hydrogen-lifted airships were used as observation platforms and bombers during the war. German count promoted the idea of rigid airships lifted by hydrogen that later were called ; the first of which had its maiden flight in 1900. Scientists with high h 2 upper percentages are perfectionists, whereas scientists with high h 2 lower percentages are mass producers. Safety and precautions Hydrogen poses a number of hazards to human safety, from potential and fires when mixed with air to being an in its pure, -free form.

Additional hydrogen can be recovered from the steam by use of carbon monoxide through the , especially with an catalyst. In more recent applications, hydrogen is used pure or mixed with nitrogen sometimes called as a for minute leak detection. It has been suggested that in order to deal with the sometimes wide variation in h for a single academic measured across the possible citation databases, one should assume false negatives in the databases are more problematic than false positives and take the maximum h measured for an academic. It is possible to try the predictions using an online tool. Archived from on 16 July 2011. He produced the next year.

Therefore, H 2 was used in the airship, which was destroyed in a midair fire over on 6 May 1937. Applications Consumption in processes Large quantities of H 2 are needed in the petroleum and chemical industries. When compared with a video creator's total view count, the h-index and g-index better capture both productivity and impact in a single metric. The study of their properties is known as and their study in the context of living is known as. Boca Raton, Florida: Chemical Rubber Company Publishing. Hirsch has demonstrated that h has high predictive value for whether a scientist has won honors like membership or the.

Binary hydride has not yet been identified, although larger complexes exist. Safety and precautions Hydrogen poses a number of hazards to human safety, from potential and fires when mixed with air to being an in its pure, -free form. It has been stated that citation behavior in general is affected by field-dependent factors, which may invalidate comparisons not only across disciplines but even within different fields of research of one discipline. Hydrogen can form compounds with elements that are more , such as e. Journal of the American Chemical Society. According to quantum theory, this behavior arises from the spacing of the quantized rotational energy levels, which are particularly wide-spaced in H 2 because of its low mass.

Typically the cathode is made from platinum or another inert metal when producing hydrogen for storage. Biochemical and Biophysical Research Communications. At very low temperatures, the equilibrium state is composed almost exclusively of the para form. Protons and acids Further information: Oxidation of hydrogen removes its electron and gives , which contains no electrons and a which is usually composed of one proton. The first non-stop transatlantic crossing was made by the British airship in 1919. The most common of hydrogen, termed protium name rarely used, symbol 1H , has one and no.

Not available with lease and some other offers. The index can also be applied to the productivity and impact of a as well as a group of scientists, such as a department or university or country. The exclusion of conference proceedings papers is a particular problem for scholars in , where conference proceedings are considered an important part of the literature. Maxwell observed that the of H 2 unaccountably departs from that of a gas below room temperature and begins to increasingly resemble that of a monatomic gas at cryogenic temperatures. Hydrogen gas was first artificially produced in the early 16th century by the reaction of acids on metals. H + 3 is one of the most abundant ions in the Universe, and it plays a notable role in the chemistry of the interstellar medium. H 2 reacts with every oxidizing element.

Among 36 new inductees in the National Academy of Sciences in biological and biomedical sciences in 2005, the median h-index was 57.

A molecular form called H + 3 is found in the interstellar medium, where it is generated by ionization of molecular hydrogen from. This method has not been readily adopted, perhaps because of its complexity. Hydrogen plays a particularly important role in because most acid-base reactions involve the exchange of protons between soluble molecules. For hydrides other than group 1 and 2 metals, the term is quite misleading, considering the low electronegativity of hydrogen. Hydrogen used in transportation would burn relatively cleanly, with some emissions, but without carbon emissions. If, however, the gas is to be burnt on site, oxygen is desirable to assist the combustion, and so both electrodes would be made from inert metals. Thermochemical There are more than 200 thermochemical cycles which can be used for , around a dozen of these cycles such as the , , , , and are under research and in testing phase to produce hydrogen and oxygen from water and heat without using electricity.
