In situ monitoring of the NaCl + HNO3 surface reaction: the observation of mobile surface strings
Article Abstract:
Atomic force microscopy (AFM) in contact mode was used in studying the reaction of single-crystal NaCl(100) with dry HNO3. The focus of the research is clarifying crystal growth in NaNO3. It has been previously reported that contact AFM is not destructive to NaCl or NaNO3 surfaces. Results show that exposures of NaCl(100) to large amounts of HNO3 with subsequent exposure to H2O leads to a surface containing rhombohedral NaNO3 crystals with the remaining surface as unreacted NaCl. The newly-exposed NaCl surface reacts further with HNO3 to form additional NaNO3.

Ultrafast shock compression of self-assembled monolayers: A molecular picture
Article Abstract:
Simulations of self-assembled monolayers are performed to interpret experimental measurements of ultrafast approximately 1GPa planar shock compression dynamics probed by vibrational sum-frequency generation (SFG) spectroscopy. Isothermal compressions help explain the time dependence of shock spectra but generally underestimate the magnitude of SFG signal loss because they do not include effects of high strain-rate dynamics and shock front and surface irregularities.

Surface phonos of D:C(001)-(2*1)
Article Abstract:
A report on the surface phonon spectrum of the deuterium-terminated D:C(001)-(2*1) surface calculated using a semiempirical total energy approach is presented. The calculated mode energies are found to be in gratifying agreement with recent electron energy loss data and allow identifying the physical origin of the measured features.
