Stabilization versus competing de-metalation, trans-metalation and (cyclo)-dehydrogenation of Pd porphyrins at a copper surface

Francesco Armillotta

Metal-porphyrins are studied intensively due their potential applications, deriving from the variety of electronic and chemical properties, tunable by selecting metal centers and functional groups. Metalation, de- and trans-metalation processes are fundame ...

Role of intercalated cobalt in the electronic structure of Co1/3NbS2

László Forró, Helmuth Berger

Co1/3NbS2 is the magnetic intercalate of 2H-NbS2 where electronic itinerant and magnetic properties strongly influence each other throughout the phase diagram. Here we report the angle-resolved photoelectron spectroscopy (ARPES) study in Co1/3NbS2. In agre ...

A Kirchhoff-like theory for hard magnetic rods under geometrically nonlinear deformation in three dimensions

Pedro Miguel Nunes Pereira de Almeida Reis, Matteo Pezzulla

Magneto-rheological elastomers (MREs) are functional materials that can be actuated by applying an external magnetic field. MREs comprise a composite of hard magnetic particles dispersed into a nonmagnetic elastomeric (soft) matrix. Hard MREs have been rec ...

High resolution CryoEM structure of the ring-shaped virulence factor EspB from Mycobacterium tuberculosis

Stewart Cole, Florence Pojer, Jérémie Piton

The EspB protein of Mycobacterium tuberculosis is a 60 kDa virulence factor, implicated in conjugation and exported by the ESX-1 system of which it may also be a component. Previous attempts to obtain high-resolution maps of EspB by cryo-electron microscop ...
