Arthritis Care &Research, EarlyView.Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

Surface Chemistry at the Nanometer Scale [PDF]
, 2011 This thesis describes research towards understanding surface chemical and physical processes, as well as their effects on the underlying substrate properties, at the nanometer and atomic scales. We demonstrate a method to tune the density of etch pits on

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Zero-bias anomaly in one-dimensional ultrathin metallic nanowires
AIP Advances, 2012 The electronic properties of ultrathin bimetallic Au/Ag nanowires with 2-3 nm in diameter were explored by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) at liquid-nitrogen temperature.

Mechanistic insights into the oxidation of catalytically relevant AgCu near‐surface alloy interfaces
Aggregate, 2022 Recent heterogeneous catalysis studies have demonstrated that synergy between Ag and Cu can lead to more selective partial oxidation chemistries. We performed a series of scanning tunneling microscope experiments to gain a better understanding of the ...

Electrochemical Scanning Tunneling Microscopy
Analytical Sciences, 1994 An ECSTM apparatus with an ideal tip using a homemade SSX-1A STM instrument has been constructed. STM and ECSTM tips were made by electrochemical etching and insulating with paraffin, silicon rubber or epoxy resin under an optical microscope. In situ imaging of highly oriented pyrolytic graphite (HOPG) shows that the leakage current passing through the

Introduction to Scanning Tunneling Microscopy [PDF]
, 1993 AbstractThe scanning tunneling microscope (STM) and the atomic force microscope (AFM), both capable of visualizing and manipulating individual atoms, are the cornerstones of nanoscience and nanotechnology today. The inventors of STM, Gerd Binnig and Heinrich Rohrer, were awarded with the Nobel Prize of physics in 1986.
