Intermediate Phase Enhances Inorganic Perovskite and Metal Oxide Interface for Efficient Photovoltaics

Michael Graetzel, David Lyndon Emsley, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Dominik Józef Kubicki, Yuhang Liu, Jiahuan Zhang, Zaiwei Wang, Aditya Mishra, Claudia Esther Avalos

Interfacial modification is crucial to fully develop the potential of semiconductor devices, including the revolutionary halide perovskite-based optoelectronics, such as photovoltaics, light-emitting diodes, and photodetectors. The all-inorganic halide per ...

Gas-sieving zeolitic membranes fabricated by condensation of precursor nanosheets

Michele Ceriotti, Kumar Varoon Agrawal, Pascal Alexander Schouwink, Luis Francisco Villalobos Vazquez de la Parra, Mostapha Dakhchoune, Claudia Esther Avalos, Yu Han, Rocio Semino Barbaresi

The synthesis of molecular-sieving zeolitic membranes by the assembly of building blocks, avoiding the hydrothermal treatment, is highly desired to improve reproducibility and scalability. Here we report exfoliation of the sodalite precursor RUB-15 into cr ...

Fast and Sensitive Detection of Paramagnetic Species Using Coupled Charge and Spin Dynamics in Strongly Fluorescent Nanodiamonds

Claudia Esther Avalos

Sensing of a few unpaired electron spins, such as in metal ions and radicals, is a useful but difficult task in nanoscale physics, biology, and chemistry. Single negatively charged nitrogen-vacancy (NV-) centers in diamond offer high sensitivity and spatia ...

Chemical exchange at the ferroelectric phase transition of lead germanate revealed by solid state Pb-207 nuclear magnetic resonance

David Lyndon Emsley, Arnaud Magrez, Brennan James Walder, Jasmine Viger-Gravel, Claudia Esther Avalos

The nature of the dynamics and structural changes that take place at the ferroelectric phase transition in lead oxides is a rich field of study. Solid-state nuclear magnetic resonance (NMR) of Pb-207 is well suited to study the local structure and disorder ...

Lead-Oxygen Bond Length Distributions of the Relaxor Ferroelectric 0.67PbMg(1/3)Nb(2/3)O(3)-0.33PbTiO(3) from Pb-207 Nuclear Magnetic Resonance

David Lyndon Emsley, Brennan James Walder, Claudia Esther Avalos

We investigate changes in the local environment of Pb-207 sites in the relaxor ferroelectric 0.67PbMg(1/3)Nb(2/3)O(3)-0.33PbTiO(3) using variable temperature magic angle spinning nuclear magnetic resonance. We observe a Gaussian distribution of Pb-207 chem ...

F-19 Magic Angle Spinning Dynamic Nuclear Polarization Enhanced NMR Spectroscopy

David Lyndon Emsley, Dominik Józef Kubicki, Jasmine Viger-Gravel, Moreno Lelli, Claudia Esther Avalos, David Benjamin Roger Antoine Gajan

The introduction of high-frequency, high-power microwave sources, tailored biradicals, and low-temperature magic angle spinning (MAS) probes has led to a rapid development of hyperpolarization strategies for solids and frozen solutions, leading to large ga ...
