Intercellular lipids comprise mainly ceramides, known to enhance the barrier function of the stratum corneum. However, the activities of ceramides inside the skin have not yet been fully elucidated. Here we examined how the human ceramide mixture (HC

We successfully observed intrinsic Josephson effects of Tl 2 Ba 2 CaCu 2 O x (Tl-2212) thin films by structuring step-edges or mesas and measuring the electrical transport properties along the c -axis. For a step-edge with the height of 350 nm, a hys

SIS-type (Superconductor-Insulator-Superconductor) intrinsic stacked Josephson junctions (ISJJs) and SNS-type (Superconductor-Normal conductor-Superconductor) step-edge Josephson junctions (SEJJs) have been successfully fabricated using anisotropic T

High-quality c-axis oriented Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub /spl delta// thin films have been prepared on MgO, which is more suitable for high frequency applications than LaAlO/sub 3/ because of its lower dielectric constant (/spl epsi/) and smal

Tl 2 Ba 2 CaCu 2 O x (Tl-2212) step-edge Josephson junctions (SEJJs) on MgO substrates have been frabricated and tested for millimeter wave applications. Although the single SEJJs exhibited clear Shapiro steps under Ka-band (27 to 40 GHz) irradiation

Starch, agarose, κ-carrageenan and porphyran were sulfated by sulfuric acid with dicyclohexylcarbodiimide as a condensation reagent. In all the cases, the sulfation at O-6 appeared to be predominant on the basis of results from methylation analyses.

We researched the microstructure and I–V characteristics of step-edge Josephson junctions in YBa2Cu3O7 (YBCO) films grown on shallow steps with angles of 19° in MgO(100) substrates. The CuO planes of the YBCO grow parallel to the MgO surface even

The authors have developed a high-impedance Josephson-type microwave detector and a practical microwave video detection system using a small Stirling refrigerator. The detector was fabricated from a newly developed YBCO-BiO composite superconductor p
