Oxygen vacancies in strained SrTiO$_{3}$ thin films: formation enthalpy and manipulation [PDF]
, 2017 We report the enthalpy of oxygen vacancy formation in thin films of electron-doped SrTiO$_{3}$, under different degrees of epitaxial stress. We demonstrate that both compressive and tensile strain decrease this energy at a very similar rate, and promote ...

De novo active sites for resurrected Precambrian enzymes
Nature Communications, 2017 The emergence of novel catalytic functions in ancient proteins likely played a role in the evolution of modern enzymes. Here, the authors use protein sequences from Precambrian beta-lactamases and demonstrate that a single hydrophobic-to-ionizable amino ...
