We first describe the history and methods of membrane protein crystallization, and show how the structure of the photosynthetic reaction centre from the purple bacterium Rhodopseudomonas viridis was solved. The structure of this membrane protein complex is correlated with its function as a light-driven electron pump across the photosynthetic membrane.(More)
Detailed studies of the subpicosecond kinetics in the primary electron transfer of reaction centers of Rhodopseudomonas viridis The primary, light-induced charge separation in reaction centers of Rhodopseudomonas widis is investigated with femtosecond time resolution. The absorption changes after direct excitation of the primary donor P at 955 nm are(More)
[11] is tricky, since the spin-coating solution does not wet the substrate and flies off the rotating surface. Since the OTS pattern after the lift-off technique is the inverse of the originally stamped ODT pattern, the sample in Figure 1d features macroscopically an oxide surface with printed OTS stripes on a micrometer lateral scale. Beyond the specific(More)
The Boréon area in the Mercantour Massif, S.E. France, was contaminated by radionuclides after the Chernobyl accident in the first days of May 1986. Sediments from a small mountain lake in this area were collected, as well as forest soils in its vicinity, in order to obtain 137Cs and 210Pb profiles. Calculated from the 210Pb inventory in a soil of a(More)
We present a thermoreflectance imaging system using a focused laser sweeping the device under test with a scanner made of galvanometric mirrors. We first show that the spatial resolution of this setup is submicrometric, which makes it adapted to microelectronic thermal measurements. Then, we studied qualitative temperature variations on two dissipative(More)
After this the polymer was rigid and could be peeled off carefully from the silicon master. The suspensions were prepared by adding powder to distilled water under constant stirring. The pH was always kept between 4 and 5 by dropwise adding a 2 M solution of hydrochloric acid (Titrisol, Merck, Darmstadt, Germany). Thereafter the suspensions were ball milled(More)
The objective of this paper is to report on the results of a study of 238Pu, 239 + 240Pu and 241Am inventories onto Blelham Tarn in Cumbria (UK). The atmospheric fallout inventory was obtained by analysing soil cores and the results are in good agreement with the literature: 101 Bq m(-2) for 239 + 240Pu; 4.5 Bq m(-2) for 238Pu and 37 Bq m(-2) for 241Am.
