The role of quartz during deformation of polyphase rocks [PDF]

open access: yes, 2013
In this thesis, deformation mechanisms, rheology and the related microstructural evolution of quartz during deformation of polyphase rocks are investigated in natural, high temperature, small scale shear zones in granitoids. Selected shear zones are from

Absolute Measurement of the Refractive Index of Water by a Mode-Locked Laser at 518 nm

open access: yesSensors, 2018
In this paper, we demonstrate a method using a frequency comb, which can precisely measure the refractive index of water. We have developed a simple system, in which a Michelson interferometer is placed into a quartz-glass container with a low expansion ...
