Comparison of microanalytical methods for estimating H20 contents of silicic volcanic glasses [PDF]

open access: yes, 1995
Three methods of estimating H20 contents of geologic glasses are compared: (1) ion microprobe analysis (secondary ion mass spectrometry), (2) Fourier-transform infrared spectroscopy (FTIR), and (3) electron microprobe analysis using the Na decay-curve ...

The generation of latent-ion-transport capacity [PDF]

open access: yes, 1959
Of the various hypotheses designed to explain the movement of ions from the environment into the plant cell, the most attractive suggests that ions traverse cell membranes in combination with an endogenously produced carrier substance.(1,2) The ...

Quantum correction for electron transfer rates. Comparison of polarizable versus nonpolarizable descriptions of solvent [PDF]

open access: yes, 1993
The electron transfer rate constant is treated using the spin-boson Hamiltonian model. The spectral density is related to the experimentally accessible data on the dielectric dispersion of the solvent, using a dielectric continuum approximation.
