Isothermal equation of state for gold with a He-pressure medium

X-Ray Diffraction under Extreme Conditions at the Advanced Light Source

“…Among optical sensors, the two most popular ones are the Raman edge of diamond (at pressures exceeding 20 GPa [108,109]) and the ruby fluorescence scale [110,111]. Diffraction standards include pressure media as mentioned above, materials such as MgO, and several metals [107,[112][113][114][115].…”

A self-consistent thermodynamic model of metallic systems. Application for the description of gold

“…The studies of gold are connected with its many technical applications, for instance, as a protective coating material, in electronics, as well as in metrology and medicine. For instance, gold provides an accurate pressure calibration for experiments conducted at high temperatures and pressures 13,16,17,23,38,40 . In recent years, gold nanoparticles attracted much attention as a class of multifunctional materials for biomedical application [41][42][43] .…”

“…As far as the experimental studies of gold are concerned, they include equation of state as well as the lattice and thermodynamic properties, both in low-temperature regime [3][4][5]8 and in high temperatures and pressures as well 1,2,7,[16][17][18]36 . At the same time, the thermodynamic and vibrational properties have been studied by the theoretical methods, including specific heat calculations 20,26 , phonon dispersion relation 10,35 , interatomic interaction and density of states 25 , Debye temperatures 21,26 , Grüneisen parameter 19 , lattice constants 36,37 and equation of state 14,23,24,[28][29][30][31][32][33] .…”

“…The properties of noble metals and, in particular, of gold have intensively been studied, both experimentally [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] and theoretically . The studies of gold are connected with its many technical applications, for instance, as a protective coating material, in electronics, as well as in metrology and medicine.…”

Effect of nanostructuration on compressibility of cubic BN

“…Neon pressure medium has been used to maintain quasi-hydrostatic conditions. Pressure was determined in situ from the calibrated shift of the ruby R 1 fluorescent line [2] and equations of state of gold [3] and neon [4]. High-brilliance focused synchrotron radiation (8×8 µm 2 ) was set to a wavelength of 0.3738(1) Å. X-ray patterns were collected using on-line large-area Bruker CCD detector (exposure time from 5 to 10 min).…”
