LiTi2O4 is a unique compound in that it is the only known spinel oxide superconductor. The lack of high quality single crystals has thus far prevented systematic investigations of its transport properties. Here we report a careful study of transport and tunnelling spectroscopy in epitaxial LiTi2O4 thin films. An unusual magnetoresistance is observed which(More)
Alpha-tocopherol is one of four tocopherol isoforms and has the highest vitamin E activity in humans. Most cultivated soybean seeds contain γ-tocopherol as the predominant form, and the ratio of α-tocopherol content to total tocopherol content (α-tocopherol ratio) is <10%. Three soybean accessions from Eastern Europe have α-tocopherol ratios of >20%. This(More)
