    The Novel ''Controlled Intermediate Nuclear Fusion'' and its Possible Industrial Realization as Predicted by Hadronic Mechanics and Chemistry

    Full text link
    In this note, we propose, apparently for the first time, a new type of controlled nuclear fusion called "intermediate" because occurring at energies intermediate between those of the ''cold'' and ''hot'' fusions, and propose a specific industrial realization. For this purpose: 1) We show that known limitations of quantum mechanics, quantum chemistry and special relativity cause excessive departures from the conditions occurring for all controlled fusions; 2) We outline the covering hadronic mechanics, hadronic chemistry and isorelativity specifically conceived, constructed and verified during the past two decades for new cleans energies and fuels; 3) We identify seven physical laws predicted by the latter disciplines that have to be verified by all controlled nuclear fusions to occur; 4) We review the industrial research conducted to date in the selection of the most promising engineering realization as well as optimization of said seven laws; and 5) We propose with construction details a specific {\it hadronic reactor} (patented and international patents pending), consisting of actual equipment specifically intended for the possible industrial production of the clean energy released by representative cases of controlled intermediate fusions for independent scrutiny by interested colleagues.Comment: 32 pages, 5 figures.

    Connecting frontier research with industrial development : Lanthanide and Actinide Chemistry in the European f-Element Network (EUFEN)

    The chemistry of f-elements, even though often not known to the general public, forms part of many industrial processes, manufacturing and medical applications, such as medical imaging (e.g. MRI scans), strong magnets, data storage media, superconducters, LEDs, catalysis, as well as energy, and metal extraction. It plays a crucial role in the scientific and industrial landscape of the European Union (EU) in fields of energy, security, training, sustainability, and society. The use of these elements widens the scope of synthetic possibilities in chemistry, and materials with outstanding electromagnetic properties have already been realised. The synthesis of lanthanide containing supramolecular materials with exceptional materials properties has already been reported, e.g. the ability to bind and release gases, high-temperature superconductivity, and all-white light emitting diodes. The EUFEN (European f-Element Network) COST action provides cooperative mobility mechanisms for nationally funded f-element chemists pursuing fundamental frontier research to initiate collaborations, training, networking, and dissemination among each other. Novel developments and results in terms of f-element crystal engineering carried out at the University of Malta are therefore part of EUFEN.peer-reviewe

    Synthesis and Isolation of Regiospecific Mono Iodo-Cyclodextrin as a Fragile Intermediate to Amino-Cyclodextrin

    lodo-CD (II) was prepared from toluenesulfonyl-CD (I) and purified by preparative HPLC. Iodo-CD (II) was easily converted to the amino-CD (III). Examination of the structure of the hydrolyzate from amino-CD (III) showed that indination and amination proceeded with inversion of configuration in both reactions

    Hydrographic observations in Elkhorn Slough and Moss Landing Harbor, California, October 1970 to November 1971. Annual report, Part 3, July 1972

    In October 1970, Moss Landing Marine Laboratories began an observational program to determine/the seasonal changes in the water chemistry of Elkhorn Slough and Moss Landing Harbor. This data report contains the first year of data (October 1970 - November 1971). These data are of immediate interest in determining the flushing and mixing mechanisms of the slough and in establishing the effect that local domestic and industrial effluents have on the distribution of these chemical parameters.

    A negative feedback between anthropogenic ozone pollution and enhanced ocean emissions of iodine

    Get PDF
    Naturally emitted from the oceans, iodine compounds efficiently destroy atmospheric ozone and reduce its positive radiative forcing effects in the troposphere. Emissions of inorganic iodine have been experimentally shown to depend on the deposition to the oceans of tropospheric ozone, whose concentrations have significantly increased since 1850 as a result of human activities. A chemistry-climate model is used herein to quantify the current ocean emissions of inorganic iodine and assess the impact that the anthropogenic increase in tropospheric ozone has had on the natural cycle of iodine in the marine environment since pre-industrial times. Our results indicate that the human-driven enhancement of tropospheric ozone has doubled the oceanic inorganic iodine emissions following the reaction of ozone with iodide at the sea surface. The consequent build-up of atmospheric iodine, with maximum enhancements of up to 70% with respect to pre-industrial times in continental pollution outflow regions, has in turn accelerated the ozone chemical loss over the oceans with strong spatial patterns. We suggest that this ocean-atmosphere interaction represents a negative geochemical feedback loop by which current ocean emissions of iodine act as a natural buffer for ozone pollution and its radiative forcing in the global marine environment.Fil: Prados Roman, C..

    The application of inelastic neutron scattering to investigate the interaction of methyl propanoate with silica

    Get PDF
    A modern industrial route for the manufacture of methyl methacrylate involves the reaction of methyl propanoate and formaldehyde over a silica-supported Cs catalyst. Although the process has been successfully commercialised, little is known about the surface interactions responsible for the forward chemistry. This work concentrates upon the interaction of methyl propanoate over a representative silica. A combination of infrared spectroscopy, inelastic neutron scattering, DFT calculations, X-ray diffraction and temperature-programmed desorption is used to deduce how the ester interacts with the silica surface

    Global Health and Economic Impacts of Future Ozone Pollution

    Abstract and PDF report are also available on the MIT Joint Program on the Science and Policy of Global Change website (http://globalchange.mit.edu/).We assess the human health and economic impacts of projected 2000-2050 changes in ozone pollution using the MIT Emissions Prediction and Policy Analysis-Health Effects (EPPA-HE) model, in combination with results from the GEOS-Chem global tropospheric chemistry model that simulated climate and chemistry effects of IPCC SRES emissions. We use EPPA to assess the human health damages (including acute mortality and morbidity outcomes) caused by ozone pollution and quantify their economic impacts in sixteen world regions. We compare the costs of ozone pollution under scenarios with 2000 and 2050 ozone precursor and greenhouse gas emissions (SRES A1B scenario). We estimate that health costs due to global ozone pollution above pre-industrial levels by 2050 will be 580billion(year2000580 billion (year 2000) and that acute mortalities will exceed 2 million. We find that previous methodologies underestimate costs of air pollution by more than a third because they do not take into account the long-term, compounding effects of health costs. The economic effects of emissions changes far exceed the influence of climate alone.United States Department of Energy, Office of Science (BER) grants DE-FG02-94ER61937 and DE-FG02-93ER61677, the United States Environmental Protection Agency grant EPA-XA-83344601-0, and the industrial and foundation sponsors of the MIT Joint Program on the Science and Policy of Global Change
