Fundamental Structure-Property Relationships Governing the Electrochemical Activity of Epitaxial Heterostructures

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Scott Chambers

Complex oxides have the widest range of properties of any class of materials explored to date. However, with many degrees of freedom come many possible outcomes. Consequently, controlled synthesis of…

Structural investigation of transcription reprogramming by E. coli stringent starvation protein A

Lead Institution

Duke University

Principal Investigator

Maria Schumacher

Stringent starvation protein A (SspA) is a global transcriptional regulator that associates with RNA polymerase (RNAP) and plays roles in the activation of the stringent response and pathogenesis in…

Protemic Analysis of Naturally Ocurring Methane Oxidizing Archaeal Communities
