36 Citations | This study demonstrates that Ti-in- quartz thermometry can yield details of rock evolution if the textural setting and reaction history of the quartz is clear, and can yield near-peak metamorphic temperatures in some cases, if care is taken to test for post-peak diffusional resetting. |
| It is also consistent with the experimental finding that the quartz recrystallized grainsize paleopiezometer is independent of temperature. | |
51 Citations | It is concluded that the incorporation of trace elements into hydrothermal quartz from Alpine veins is influenced by growth mechanisms and surface-structures of the growing quartz crystals, the influence of which may change as a function of temperature, pH, as well as the chemical composition of the fluid. |
| It is shown that a thermally activated conduction mode is realized in such structures. | |

32 Citations | Both, the electrical conductivity and relaxation appear to be thermally activated. |
43 Citations | This is consistent with observations made in studies of synthetic quartz [Bejina and Jaoul, Phys. |
| The Vogel-Tamman-Fulcher (VTF) plots suggest that the temperature dependence of conductivity is a thermally activated process. | |
| It has a larger electromechanical coupling factor compared to quartz and also nearly the same temperature stability as quartz. | |
| Based on the most reliable of these data, the least squares method is used to derive an equation which approximates the temperature dependence of the thermal conductivity coefficient in the range of 600–1500 K. The possibility of application of optical quartz glass as a reference substance for determining the thermal conductivity coefficient of partially transparent materials under conditions of simultaneous radiative-conductive transfer of energy is substantiated. | |
161 Citations | The annealed quartz ( 450 ∘ C , 45 min) has an α -value of 0.030 ± 0.001 which is similar to the α -value of 0.029 ± 0.001 for the non-annealed quartz extracts, suggesting that the α -value is independent of the quartz's thermal history for this sample. |
| (3) Replacement of quartz by calcite and calcite by quartz may be caused by transport of CaCO 3 and SiO 2 along thermal gradients. | |
71 Citations | The steady-state temperature rise of an individual nanodisk has comparable contributions from the thermal conductance of the Au/quartz interface and heat spreading in the quartz substrate. |
19 Jun 1978 | Since the existing temperature derivatives are not with respect to the fundamental elastic constants, they cannot conveniently be employed in calculations of thermally induced frequency changes in electroded quartz resonators. |
05 Jun 1996 | However, the latter can be neglected for a quartz substrate. |
51 Citations | Analysis of these data by reverse Monte Carlo modeling indicates that between 200 and 400 °C, the local disorder in the instantaneous structure of α-quartz becomes comparable to that of β-quartz. |

How does copper have more thermal conductivity than brass?4 answersCopper has higher thermal conductivity than brass due to its crystal structure and composition. Copper samples prepared using metal-filled polymers and thermal treatment processes showed significantly improved thermal conductivity, achieving values of approximately 30 W/mK. On the other hand, the thermal conductivity of brass was measured to be 110.2 Wm-1 K-1. The difference in thermal conductivity can be attributed to the presence of other elements in brass, such as zinc, which can disrupt the crystal structure and impede the flow of heat. Additionally, the presence of a three-dimensionally interconnected graphene network in copper composites can act as a barrier to heat transfer, resulting in enhanced thermal conductivity. Therefore, the combination of copper's crystal structure, composition, and the presence of impurities or reinforcements in brass can explain why copper exhibits higher thermal conductivity than brass.
