Pseudo-two-girdles c-axis fabric patterns in a quartz-feldspar mylonite (Costabona granodiorite, Canigo massif) [PDF]

open access: yes, 2012
An example of the relationship that exist between the preferred crystaliografic orientation of quartz grains and the attitude of the mylonite foliation of quartz-feldspar mylonites is described. These rocks are the result of the inhomogeneous deformation

Preliminary results for the extraction and measurement of cosmogenic in situ C-14 from quartz [PDF]

open access: yes, 2004
Radiocarbon is produced within minerals at the earth's surface (in situ production) by a number of spallation reactions. Its relatively short half-life of 5730 yr provides us with a unique cosmogenic nuclide tool for the measurement of rapid erosion ...

Plaid-Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe<sub>2</sub>. [PDF]

open access: yesAdv Sci (Weinh)
Helicity‐ and angle‐resolved Raman spectroscopy reveals chiral magnons in the non‐coplanar antiferromagnet MnTe 2. Combined with first‐principles calculations and spin‐wave theory, the results establish its altermagnetic character through circular Raman dichroism, reduced rotational symmetry, and a distinctive plaid‐like momentum‐space magnon spin ...

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

The Quartz Crystal Microbalance as a Microviscometer for Improved Rehabilitation Therapy of Dysphagic Patients. [PDF]

open access: yes, 2005
The viscosity of non-solid foods, and the stability of their viscosity over time, temperature change and shearing is critical in managing dysphagia.

The problem of dating quartz 1 : Spectroscopic ionoluminescence of dose dependence [PDF]

open access: yes, 2010
This work is partially supported by NERC studentship F008589/1.A suite of quartz samples of different provenances, irradiation, thermal and depositional histories were analysed using spectroscopic ionoluminescence (IL) to investigate variations in ...

ST Quartz Acoustic Wave Sensors with Sectional Guiding Layers [PDF]

open access: yes, 2008
We report the effect of removing a section of guiding layer from the propagation paths of ST-quartz Love wave sensors; this offers the ease of fabrication of a polymer guiding layer whilst retaining the native surface of the quartz which may then be used

Thermodynamic analysis of two-step solar water splitting with mixed iron oxides [PDF]

open access: yes, 2009
A two-step thermochemical cycle for solar production of hydrogen from water has been developed and investigated. It is based on metal oxide redox pair systems, which can split water molecules by abstracting oxygen atoms and reversibly incorporating ...

The effect of SU-8 patterned surfaces on the response of the quartz crystal microbalance [PDF]

open access: yes, 2005
In this work we present data showing the effect of patterning layers of SU-8 photoresist on a quartz crystal microbalance (QCM) and subsequent chemical treatment to increase their hydrophobicity. Patterns with 5 mu m diameter pillars spaced every 10 mu m
