Empirical Gibbs functions estimate free energies of non-covalent reactions (deltaG) from atomic coordinates of reaction products (e.g. antibody-antigen complexes). The function previously developed by us has four terms that quantify the effects of hydrophobic, electrostatic and entropy changes (conformational, association) upon complexation. The function(More)
Direct measurements of longitudinal (d/sub 33/) and transverse (d/sub 31/) coefficients have been made on single crystal 0.68Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-0.32PbTiO/sub 3/ (PMN-32PT) and 0.955Pb(Zn/sub 1/3/Nb/sub 2/3/)O/sub 3/-0.045PbTiO/sub 3/ (PZN-4.5PT), poled along the [001]/sub C/ direction (C: pseudocubic). The measurements were made in a(More)
[1] Morainal banks are primary features at the margins of advancing and stable to quasi-stable temperate tidewater glaciers, yet their roles in glacier dynamics and terminus stability are poorly defined by submarine observations. Analysis of new and archival multibeam data and Landsat images of the advancing Hubbard Glacier, southeast Alaska, reveal that(More)
The pyroelectric coefficients of 0.72Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-0.28PbTiO/sub 3/ (PMN-28PT), 0.67Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-0.33PbTiO/sub 3/ (PMN-33PT) and 0.92Pb(Zn/sub 1/3/Nb/sub 2/3/)O/sub 3/-0.08PbTiO/sub 3/ (PZN-8PT) single crystals, oriented and poled along the [001]/sub c/, [101]/sub c/ and [111]/sub c/ directions (C: pseudocubic)(More)
The importance of a high shear coefficient d<sub>15</sub> to the piezoelectric properties of domain-engineered perovskite crystals is discussed. The terms "rotator" and "extender" are introduced to differentiate the contrasting behaviors of 4mm BaTiO<sub>3</sub> and PbTiO<sub>3</sub>. In "rotator" ferroelectrics, where d<sub>15</sub> is high, polarization(More)
