Visualizing the impact of chloride addition on the microscopic carrier dynamics of MAPbI3 thin films using femtosecond transient absorption microscopy

Journal article The Journal of Chemical Physics · December 21, 2019 Featured Publication The spatial heterogeneity of carrier dynamics in mixed halide perovskite CH3NH3PbI3−xClx thin films with a range of different chloride additions is mapped using femtosecond transient absorption microscopy (TAM). The comparison of TAM images of fibr ... Full text Cite

Decoupled LIGHT-SABRE variants allow hyperpolarization of asymmetric SABRE systems at an arbitrary field.

Journal article Journal of magnetic resonance (San Diego, Calif. : 1997) · October 2019 Featured Publication Signal Amplification By Reversible Exchange, or SABRE, uses the singlet-order of parahydrogen to generate hyperpolarized signals on target nuclei, bypassing the limitations of traditional magnetic resonance. Experiments performed directly in the magnet pro ... Full text Cite

Selective hyperpolarization of heteronuclear singlet states via pulsed microtesla SABRE.

Journal article The Journal of chemical physics · July 2019 Featured Publication Signal Amplification By Reversible Exchange (SABRE) and its heteronuclear variant SABRE in SHield Enables Alignment Transfer to Heteronuclei create large nuclear magnetization in target ligands, exploiting level crossings in an iridium catalyst that transi ...
