Beckmann rearrangements of oximes to lactams often require harsh conditions and/or the use of large amounts of acid catalyst. To reduce the amount of Bronsted acid required, and to avoid the formation of a large amount of undesirable byproducts under

The Beckmann rearrangement of cyclohexanone oxime was achieved by the combined use of cobalt salt and Lewis acids co-catalysts (each 10 mol%). Various combinations of cobalt salts and Lewis acids gave lactams in a satisfactory yield under mild condit

An efficient transformation of polyamides to ω-hydroxy alkanoic acids was achieved. Treatment of nylon-12 with supercritical MeOH in the presence of glycolic acid gave methyl ω-hydroxydodecanoate in 85% yield and the alcohol/alkene selectivity in t

C-axis oriented ultrathin films with good crystallinity were deposited by laser ablation on both SrTiO3 and NdGaO3 substrates. The full width at the half maximum of the rocking curves of the (005) peak δω of our ultrathin films with thickness d ≤

We have studied the superconducting Bi–Sr–Ca–Cu–O thin films prepared by metalorganic chemical vapor deposition (MOCVD). The thin films fabricated on an MgO(110) single crystal substrate show a preferential (110) orientation. The fabrication

High T c Bi-based superconductors are easily cleaved between the Bi-O layers. Therefore, most tunneling spectra so far were measured through the Bi-O layer. It is also interesting to study spectra for tunneling parallel to the a-b plane. We studied t

a-Axis oriented BiSrCaCuO thin films weere prepared at substrate temperatures of 720−850°C on (100) MgO substrates by MOCVD. The a-axis oriented BiSrCaCuOthin films were found to grow preferentially at lower substrate tempe

Non-resonant microwave absorption (NRMA) studies have been done for Bi-Sr-Ca-Cu-O (BSCCO) films with thicknesses of 30 Å and 15 Å fabricated on MgO substrate by MOCVD. For the latter two kinds of samples have been fabricated: BSCCO/MgO and BiOx/BSC
