We report on a nuclear magnetic resonance (NMR) study of ultrananocrystalline diamond (UNCD) materials produced by detonation technique. Analysis of the <Superscript>13</Superscript>C and <Superscript>1</Superscript>H NMR spectra, spin-spin and spin-lattice relaxation times in purified UNCD samples is presented. Our measurements show that UNCD...</superscript></superscript>

Sub-seabed disposal is the safest disposal option for CO2. Water pressure and dilution into oceanic water prevent direct emission of CO2 into the air. Sediments under the deep sea floor are usually cool because the deep oceanic water is very cool. CO2 hydrate forms in the sediments in areas of...
