Estimating the performance of remote phosphor SSL devices by simulations

Autor: J. Muschaweck, C.-H. Wiesmann, A. Linkov

Publikováno v: SPIE Proceedings.

For Solid State Lighting devices thermal management has a great impact on the performance. Therefore, it is necessary to analyze thermal and optical behavior simultaneously due to the mutual interaction between the two. For a remote phosphor configur

KCa chronology of lunar granites

Autor: H Wiesmann, C.-Y. Shih, L.E Nyquist

Publikováno v: Geochimica et Cosmochimica Acta. 57:4827-4841

K-Ca age determinations were undertaken for three lunar granitic samples (14321, 1062, 14303,206, and 12013,141). KCa isotopic analyses of bulk samples of seven pristine lunar igneous rocks including four mare basalts (10017, 15555, 14321, 1394, a

Rb-Sr and Sm-Nd chronology of an Apollo 17 KREEP basalt

Autor: L. E. Nyquist, B. M. Bansal, C.-Y. Shih, H. Wiesmann

Publikováno v: Earth and Planetary Science Letters. 108:203-215

The paper determines Sm-Nd and Rb-Sr mineral isochrons for an Apollo 17 KREEP (pigeonite) basalt clast from breccia 72275 collected from Boulder 1, Station 2 in the Valley of Taurus-Littrow. Sm-Nd analyses of the basalt yield a precise mineral isochr

X-ray-absorption fine-structure studies of superconductingTl2CaBa2Cu2Oxthin films

Autor: H. Wiesmann, D. Dimarzio, S. M. Heald, D. H. Chen

Publikováno v: Physical Review B. 42:294-300

Superconducting Tl-Ca-Ba-Cu-O thin films have been prepared by the technique of reactive magnetron sputtering using targets of Tl, Ca-Ba, and Cu. Three films with different quality superconducting transitions were fabricated and analyzed. X-ray-absor

Repositioning of a Domain in a Modular Polyketide Synthase to Promote Specific Chain Cleavage

Autor: Gareth A. Roberts, Jesus Cortes, Murray J. B. Brown, Peter F. Leadlay, Kirsten E. H. Wiesmann, James Staunton

Publikováno v: Science. 268:1487-1489

Macrocyclic polyketides exhibit an impressive range of medically useful activities, and there is great interest in manipulating the genes that govern their synthesis. The 6-deoxyerythronolide B synthase (DEBS) of Saccharopolyspora erythraea, which sy
