We demonstrate the fabrication of hexagonal pyramid shaped light-emitting diodes (LEDs), “mega-cone” LEDs based on ZnO/GaN wafer bonding. Compared with a conventional type LEDs with thin Ni/Au p-type electrode, external quantum efficiency was 3.1

Some recent finds from two working pits in the outwash sands of the Cheshire Plain are recorded. The opportunity is taken to discuss the dating and ecology of the fauna in relation to past and present theories of environment in the late Pleistocene,

This magnalithofacies, which forms the bulk of two formations, the Bunter Pebble Beds and the Lower Keuper Sandstone, is described and interpreted as the deposits of former low-sinuosity, largely braided, streams which flowed across a regional palaeo

Three homologous ω-mercaptosulfones have been prepared and their crystal structures refined. When a single methylene (compound 3) was interposed between the p-toluenesulfonyl and thiol moieties, neither intramolecular nor intermolecular H-bonding wa

Leptin regulates body weight by its receptor-mediated anorectic, thermogenic and antisteatotic effects. Recently, lower leptin binding to the soluble form of the leptin receptor (LEPR) was shown in carriers of the Arg223-encoding allele of the Gln223

Photoelectron angular distributions have been measured in the energy regions between the 2 P 3/2 and 2 P 1/2 states of Kr + and Xe + containing the ( 2 P 1/2 )nd′ and ( 2 P 1/2 )(n+2)s′ autoionising resonances. A new magnetic angle-changing techn

The threshold photoelectron (TPE) spectrum of SF6 has been recorded over the photon energy range 25-140 eV using synchrotron radiation and a penetrating-field electron spectrometer. In addition, the photo-double ionization spectrum of SF6 has been ob

Monochromatic synchrotron radiation was used to selectively excite core electrons of the carbon and oxygen atoms in acetaldehyde, propionaldehyde and acetone, creating neutral core-excited resonance states. Electron energy spectra associated with aut

We have measured the photon energy dependence of electric-dipole{endash}quadrupole interference in cadmium between the odd parity 4d{sup 9}5s{sup 2}5p J=1 and even parity 5p6p {sup 3} P{sub 2} autoionizing levels. The resonant interference structure
