Hydrogen Production from Renewable Bio-Based Sources
(2014-05-02)
Efficient means of power generation is the key to coping with increasing energy demands due to population expansion. Non-renewable sources like fossil fuels, coal, and methane contribute to the carbon footprint, resulting ...
Hydrogen Production in Supercritical Water
(2011-04-15)
Hydrogen has been considered as an environmentally friendly energy carrier for the future. It is not found freely in nature but must be obtained by processing hydrogen containing compounds. Current industrial-scale ...
Hydrogen Production Via Thermocatalytic Decomposition of Methane Using Carbon Supported Materials
(2018-01-09)
Convectional hydrogen (H2) production process such as steam methane reforming process (SMR) produces massive amounts of CO2 (i.e., 13.7 kg CO2 per kg H2 production). Because of the large amount of CO2 production during the ...
Hydrogeology and Geochemistry of Arsenic Contaminated Shallow Alluvial Aquifers in Florida and Alabama
(2016-06-13)
This study integrates groundwater geochemical data and modeling with hydrogeological modeling to study the geochemistry and hydrogeology of arsenic contaminated shallow alluvial aquifers in Florida and Macon County, Alabama. ...
Hydrological and geochemical analyses of the karstic Bobcat Cave watershed: A case study at Redstone Arsenal, northern Alabama
(2017-06-29)
Hydrologic, geochemical, and stable isotope methods were applied to study karstic carbonate watersheds of Redstone Arsenical (RSA) in north-central Alabama near Huntsville. Delineation of flow paths in RSA watersheds near ...
Hydrological link between the Amazon River Basin and the eastern Guiana Shield on the Neotropical ichthyofauna
(2011-11-30)
The seasonal inundation of the Rupununi savannas in south central Guyana allows for
potential faunal exchange between the Takutu and Rupununi Rivers and ultimately between the
Essequibo and Amazon Rivers. This hydrological ...
Hydrology and Water Chemistry in Weeks Bay, Alabama: Implications for Mercury Bioaccumulation
(2007-08-15)
Recent studies within Weeks Bay, an estuary of Mobile Bay, have revealed that both water and fish are contaminated by mercury (Hg), an element known to be extremely toxic to wildlife and humans. Seasonal variations of ...
Hydrology, Water Quality, and Channel Morphology Across an Urban-rural Land Use Gradient in the Georgia Piedmont, USA
(2005-12-15)
The southeastern United States is experiencing rapid urban development. Consequently, Georgia’s streams have been threatened by hydrologic alteration, nutrient and bacteriological impairment, and channel morphometry changes ...
Hydromorphology and Plinthite Characterization of Some Alabama Coastal Plain Soils
(2007-12-15)
Estimating seasonal high water tables (SHWTs) within soils by the evaluation of redoximorphic features is critical for soil interpretations. Certain redoximorphic features indicate contemporary moisture regimes, while ...
Hydrothermal Liquefaction of Algae for Bio-oil Production
(2014-12-09)
Increased demand of energy, depletion of fossil fuel resources, global warming and energy security issues have led to extensive research in renewable energy source. Among the different renewable energy sources, biomass is ...
Hydrothermal Liquefaction of Municipal Sludge and Biocrude Upgrading Using Carinata Oil
(2020-07-17)
Crude oil is a finite resource. Due to an advancement in technology, it is now possible to produce petroleum from very tight and hard reservoir formations. However, the global outcry towards the adoption of sustainable and ...
Hydrothermal Syntheses, Structures, and Properties of New Iodate and Selenite Compounds of Transition Metals, Lanthanides, and Actinides
(2007-12-15)
Iodate and selenite anions possessing a nonbonding, but stereochemically active lone pairs of electrons, were selected as building blocks to produce new compounds with noncentrosymmetric structures, a prerequisite for ...
Hydrothermal Synthesis and Characterization of Novel Thorium, Uranium, and Neptunium Solids
