Molecular Ionization from Carbon Nanotube Paper
TL;DR: Ambient ionization is achieved by spraying from a carbon nanotube (CNT)-impregnated paper surface under the influence of small voltages (≥3 V), and organic molecules give simple high-quality mass spectra without fragmentation in the positive or negative ion modes.

Zero Volt Paper Spray Ionization and Its Mechanism.
Michael Wleklinski,Yafeng Li,Soumabha Bag,Depanjan Sarkar,Rahul Narayanan,Thalappil Pradeep,R. Graham Cooks +6 more
TL;DR: A Monte Carlo simulation based on statistical fluctuation of positive and negative ions in solution has been implemented and predicts detection limits similar to those observed experimentally and explains the effects of binary mixture components on relative ionization efficiencies.

Anisotropic Molecular Ionization at 1 V from Tellurium Nanowires (Te NWs).
Rahul Narayanan,Depanjan Sarkar,Anirban Som,Michael Wleklinski,R. Graham Cooks,R. Graham Cooks,Thalappil Pradeep +6 more
TL;DR: Analysis of a variety of analytes, including amino acids, pesticides, and drugs, in pure form and in complex mixtures, is reported, suggesting that 1D nanostructure in general could be excellent ionization sources.
Probing Coordination Complexes by Carbon Nanotube-Assisted Low-Voltage Paper Spray Ionization Mass Spectrometry
TL;DR: Fragile transition metal complex ions such as [Cr(H2O)4Cl2]+, difficult to be observed by gas-phase spectroscopy, are detected easily with carbon nanotube (CNT)-assisted low-voltage ambient ionization mass spectrometry.

Studying Reaction Intermediates Formed at Graphenic Surfaces
TL;DR: In-situ production and detection of intermediates at graphenic surfaces, especially during alcohol oxidation, are reported, opening up a new pathway for different industrially and energetically important reactions using different metal catalysts and modified substrate.
