Quartz crystal microbalance with dissipation monitoring (QCMD) is a simple and versatile sensing technique with applications in a wide variety of academic and industrial fields, most notably electrochemistry, biophysics, quality control, and environmental monitoring. QCMD is limited by a relatively poor time resolution, which is of the order of seconds

Phase Noise Transfer in High-Q Quartz Phononic Frequency Combs
2020 IEEE International Ultrasonics Symposium (IUS), 2020We report on observing significant reduction of injected phase noise (more than 20 dB over two decades with a peak reduction of 29 dB) on particular comb teeth in high-Q, phononic frequency combs in AT-cut 100-MHz shear-mode quartz resonators. A frequency comb with teeth spacing of 135 kHz was observed on the fundamental mode resonance when driven off ...

Abstract The origin of zonal mineralization in porphyry copper deposit is important for understanding the mineralization processes. We propose a new, modified “orthomagmatic” genetic model for mineralization zoning in hypogene porphyry copper deposits.

Feasible Coupling Design for Compact Optical Frequency Comb based on A Fused-quartz Micro-resonator
Asia Communications and Photonics Conference 2015, 2015Optical comb spacing of 2.5 nm was generated from fused-quartz micro-resonator with Q ~ 107. An electromagnet is utilized to connect between a translation stage and the micro-resonator holder temporally for performing a portable design.

ABSTRACT:Comb-layered quartz is a type of unidirectional solidification texture found at the roofs of shallow silicic intrusions that are often associated spatially with Mo and W mineralisation. The texture consists of multiple layers of euhedral, prismatic quartz crystals (Type I) that have grown on subplanar aplite substrates.

Crystals that are simultaneously ?(2)- and ?(3)-active offer a wide range of possibilities for the generation of new coherent wavelengths of light. Frequency conversion processes such as stimulated Raman scattering, second and third harmonic generation, or parametric sum and difference frequency mixing can be combined effectively in the same ...

An Averaging Method for Phase Noise Studies of Quartz Phononic Frequency Combs
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2023A fast and accurate averaging method was derived and developed for the analysis and design of quartz phononic frequency combs. The phononic frequency combs were obtained from a pair of coupled nonlinear Duffing equations for quartz resonators by solving the equations in the time domain and performing a fast Fourier transformation (FFT) of the steady ...
