Producing absorption mode Fourier transform ion cyclotron resonance mass spectra with non-quadratic phase correction functions

Yury Tsybin, Anton Kozhinov, Konstantin Nagornov, Konstantin Zhurov

RATIONALE: Previously described methods for producing absorption mode Fourier transform ion cyclotron resonance (FTICR) mass spectra have all relied on the phase correction function being quadratic. This assumption has been found to be invalid for some ins ...

Chemical Modification of Graphene via Hyperthermal Molecular Reaction

Klaus Kern, Marko Burghard, Stephan Rauschenbach, Sabine Abb, Gordon Rinke

Chemical functionalization of graphene is achieved by hyperthermal reaction with azopyridine molecular ions. The one-step, room temperature process takes place in high vacuum (10(7) mbar) using an electrospray ion beam deposition (ES-IBD) setup. For ion su ...
