A new sustainable hydrogen clean energy paradigm
International Journal of Hydrogen Energy, 2018 Abstract We analyze the feasibility of a novel, hydrogen fuel cell electric generator to provide power with zero noise and emissions for myriad ground based applications. The hydrogen fuel cell electric generator utilizes a novel, scalable apparatus that safely generates hydrogen (H2) on demand according to a novel method, using a controlled chemical

New paradigms in sustainable energy systems with hydrogen
Energy Conversion and Management, 2023Climate change, disturbance of the energy security resulting from increasing fuel prices due to conflicts, and disruptions to production and supply chains caused by COVID-19 have highlighted the need for the world to be prepared for future challenges. The environmental and climate change impacts of heavy use of fossil fuels for energy production have ...

The Green Hydrogen Paradigm Shift
Cogeneration and Distributed Generation Journal, 2007The change from a global economy dependent upon fossil fuels torenewable fuels for an hydrogen economy is occurring now. Not in 50 to60 years, but the hydrogen economy is underway today. This “paradigmshift” is one as signi ficant and dramatic as the Industrial Revolutionitself.

The Fractional Hydrogen Atom: A Paradigm for Astrophysical Phenomena
Journal of Modern Physics, 2012 We have found that fractional principal quantum numbers are permitted in hydrogen atom which yield the conditions for neutron and white dwarf stars evolution. The number densities of neutron and white dwarf stars reveal that these systems have the maximal conductivity of 1.37×1010Ω-1m-1.

Hydrogen Exchange Kinetics of RNase A and the Urea:TMAO Paradigm
Biochemistry, 2003A key paradigm in the biology of adaptation holds that urea affects protein function by increasing the fluctuations of the native state, while trimethylamine N-oxide (TMAO) affects function in the opposite direction by decreasing the normal fluctuations of the native ensemble.

The green hydrogen paradigm shift: Energy generation for stations to vehicles
Utilities Policy, 2008Abstract The change from a global economy dependent upon fossil fuels to renewable fuels for the hydrogen economy is occurring now. Not in 50–60 years, but the hydrogen economy exists today. This is a “paradigm shift” of such significance and so dramatic as to underlie the making of the Third Industrial Revolution.

Proton and hydrogen atom transfer in hydrogen bonded clusters: Ammonia as a paradigm
The Journal of Chemical Physics, 1997The competition between proton and hydrogen atom transfer in ammonia clusters is studied in the excited C̃′ state using femtosecond pump-probe spectroscopy. Little effect of solvation is seen for the case of proton transfer, while the hydrogen transfer processes display significant dependence on the degree of clustering.

Investigating the "mixoplankton" paradigm using hydrogen isotope ratios
2023Since micro-organisms were first visualised by Robert Hooke and Antoni van Leeuwenhoek, bacteria and protists were quickly categorised as either primary producers or consumers and thus forming the base of the marine food web. New conceptual understanding sees this traditional dichotomy between autotrophs and heterotrophs in the marine food web replaced

Alkyne hydrogenation over Pd catalysts: A new paradigm
Journal of Catalysis, 2006The hydrogenation of 1-pentyne over various palladium catalysts was studied under various conditions. In the regime of selective hydrogenation, as observed by in situ X-ray photoelectron spectroscopy, significant amounts of subsurface carbon and a Pd-C surface phase built up in the early stage of the reaction.
