Ppcdt / Qui / 58985 / 2004 Pi

I became PI for this project in August 2006, following the sad loss of Professor António Xavier. At the time, Pedro Quintas was employed by this project as a BI and he had been given extensive training in biophysical methods. Our first priority was the production of a series of mutants of cytochrome c” from Methylophilus methylotrophus designed to probe the mechanism of ligand exchange. Despite...

L'arbre qui cache la forêt

Le lupus est une pathologie chronique, qui évolue par poussées. Son expression clinique est très polymorphe et chaque symptôme peut être inaugural. Il peut débuter dès l'enfance, ces formes sont rares et de pronostic sévère. Le déficit en fractions du complément constitue l'un des principaux facteurs génétiques prédisposant au lupus érythémateux systémique. Nous rapportons un cas de lupus éryth...

Nioboaeschynite-(Ce), Ce(NbTi)O6

Nioboaeschynite-(Ce), ideally Ce(NbTi)O(6) [cerium(III) niobium(V) titanium(IV) hexa-oxide; refined formula of the natural sample is Ca(0.25)Ce(0.79)(Nb(1.14)Ti(0.86))O(6)], belongs to the aeschynite mineral group which is characterized by the general formula AB(2)(O,OH)(6), where eight-coordinated A is a rare earth element, Ca, Th or Fe, and six-coordinated B is Ti, Nb, Ta or W. The general st...

Photoionization of Ce 3+ -ce

Photoionization of the Ce Ce process has been studied using the random phase approximation with exchange method in the energy region 100-150 eV. Comparison of our results with the recent measurement [Müller et al, Phys. Rev. Lett. 101, 133001 (2008)] confirms the suppression effect of the carbon cage in the endohedral fullerene Ce@C+82 photoionization. The reasons for the cause of the confineme...
