Use of asymmetric dual-cavity filters to track small H and L variations as a tool to increase yield of DWDM filters
Autor: Arthur T. Howe, Mervyn Davis, David Ian Charles Pearson, Paul Luff
Publikováno v: SPIE Proceedings.
We show that asymmetric dual cavity filters, comprising one cavity of Ta 2 O 5 (H) and the other of SiO 2 (L), can be designed so that the asymmetry in the transmission intensity between the two peaks is sensitive enough to detect H/L ratio changes d

Photoelectrochemical Cells of the Electrolyte‐Metal‐Insulator‐Semiconductor (EMIS) Configuration: II . Use of Non‐native Oxides in Pt/oxide/n‐Si Systems
Autor: Theo H. Fleisch, Arthur T. Howe
Publikováno v: Journal of The Electrochemical Society. 134:72-76
The authors studied photoelectrodes of the type Pt/oxide/n-Si in both aqueous iodine and bromine solutions, in which the tunnel oxide layer, of about 10A thickness, comprised of such non-native oxides as MgO, CaO, Al/sub 2/O/sub 3/,ZrO/sub 2/, TiO/su

Studies of layered uranium (VI) compounds. V. Mechanisms of densification of hydrogen uranyl phosphate tetrahydrate (HUP): Pressure-induced planar glide and solution phase sintering
Autor: Arthur T. Howe, Mark G. Shilton, Peter E. Childs
Publikováno v: Journal of Solid State Chemistry. 34:341-346
The good proton conductor HUO 2 PO 4 ·4H 2 O (HUP) can be easily fabricated into disks or films suitable for use in electrochromic displays, fuel cells, or batteries. Kinetic studies of the room-temperature densification reveal the presence of two m

Proton conducting membranes composed of hydronium alunite
Autor: Arthur T. Howe, Misri Lal, Yakesun Wing
Publikováno v: Materials Research Bulletin. 15:1649-1654
High proton conductivity, of 3 × 10−4 ohm−1 cm−1 at 20°C, has been found in hydrated pressed discs of hydronium alunite, of formula (H3O)Al3(SO4)2(OH)6. The conduction occurs within the hydrated interparticle regions into which protons have b

Studies of layered uranium(VI) compounds. IV. Proton conductivity in single-crystal hydrogen uranyl phosphate tetrahydrate (HUP) and in polycrystalline hydrogen uranyl arsenate tetrahydrate (HUAs)
Autor: Mark G. Shilton, Arthur T. Howe
Publikováno v: Journal of Solid State Chemistry. 34:149-155
Single-crystal measurements on hydrogen uranyl phosphate tetrahydrate, HUO 2 PO 4 ·4H 2 O (HUP), have confirmed that the high proton conductivity is a bulk characteristic. The conductivity values were in substantial agreement with those previously r

N.M.R. study of hydrogen motion in hydrogen uranyl phosphate (HUP) and hydrogen uranyl arsenate (HUAs)
Autor: Peter E. Childs, Arthur T. Howe, Thomas K. Halstead, Mark G. Shilton
Publikováno v: Materials Research Bulletin. 13:609-619
Pulsed /sup 1/H n.m.r. measurements were made of relaxation times in hydrogen uranyl phosphate and arsenate, which are fast proton conductors. Both compounds were found to undergo a phase transition resulting in discontinuities in T/sub 1/ and T/sub
