Investigation of the Cs(Mo,Te)O Solid Solution and Implications on the Joint Oxyde-Gaine System in Fast Neutron Reactors.

The formation of a thin layer, the so-called Joint Oxyde-Gaine (JOG), between the (U,Pu)O fuel pellets and the cladding has been observed in fast neutron reactors, due to the accumulation of volatile fission products. CsMoO is known to be one of the major components of the JOG, but other elements are also present, in particular tellurium and palladium. In this work, an investigation of the structural and thermodynamic properties of CsTeO and CsMoTeO solid solution is reported.

Stability and function of the Sec61 translocation complex depends on the Sss1p tail-anchor sequence.

Sss1p, an essential component of the heterotrimeric Sec61 complex in the ER (endoplasmic reticulum), is a tail-anchored protein whose precise mechanism of action is largely unknown. Tail-anchored proteins are involved in many cellular processes and are characterized by a single transmembrane sequence at or near the C-terminus. The Sec61 complex is the molecular machine through which secretory and membrane proteins translocate into and across the ER membrane.
