Ab initio studies of strained wurtzite GaN surfaces (2004)
Journal Article
Timon, V., Brand, S., Clark, S., & Abram, R. (2004). Ab initio studies of strained wurtzite GaN surfaces. Journal of Physics: Condensed Matter, 16(4), 531-542. https://doi.org/10.1088/0953-8984/16/4/002

In GaN and other group III nitrides the considerable lattice mismatch with the substrates normally employed during growth, such as sapphire, 6H-SiC and ZnO, can lead to the presence of strain which may affect the surface properties. Here we have stud... Read More about Ab initio studies of strained wurtzite GaN surfaces.

The use of calcium silicate bricks for retrospective dosimetry (2004)
Journal Article
Bailiff, I., & Mikhailik, V. (2004). The use of calcium silicate bricks for retrospective dosimetry. Radiation Measurements, 38(1), 91-99. https://doi.org/10.1016/j.radmeas.2003.07.004

The suitability of calcium silicate bricks (CSBs) for the retrospective measurement of gamma dose using luminescence techniques has been investigated. Bricks of this type are distinguished from fired clay bricks by containing negligible clay and requ... Read More about The use of calcium silicate bricks for retrospective dosimetry.

Effect of axial strain cycling on the critical current density andn-value of ITER niobium-tin wires (2004)
Journal Article
Taylor, D., & Hampshire, D. (2004). Effect of axial strain cycling on the critical current density andn-value of ITER niobium-tin wires. Physica C: Superconductivity and its Applications, 401(1-4), 40-46. https://doi.org/10.1016/j.physc.2003.09.009

Measurements have been made of the effect of axial strain cycling on the critical current density and n-value of two ITER candidate niobium-tin wires (Europa Metalli-LMI (EM-LMI) and Vacuumschmelze). The wires were subjected to similar to1300 strain... Read More about Effect of axial strain cycling on the critical current density andn-value of ITER niobium-tin wires.

Crystal, Molecular and Electronic Structure of N,N'-diphenyl-N,N'-bis(2,4-dimethylphenyl)-(1,1'-biphenyl)-4,4'-diamine and the Corresponding Radical Cation. Chemistry - A European Journal, 10(1), 83-91. https://doi.org/10.1002/chem.200305200

Oxidation of N,N'-diphenyl-N,N'-bis(3-methylphenyl)-(1,1'-biphenyl)-4,4'-diamine (TPD, 1a) and N,N'-diphenyl-N,N'-bis(2,4-dimethylphenyl)- (1,1'-biphenyl)-4,4'-diamine (1b) with SbCl5 affords the corresponding radical cations quantitatively. The crys... Read More about Crystal, Molecular and Electronic Structure of N,N'-diphenyl-N,N'-bis(2,4-dimethylphenyl)-(1,1'-biphenyl)-4,4'-diamine and the Corresponding Radical Cation.

Two-photon excitation and luminescence of a CaWO4 scintillator (2004)
Journal Article
Mikhailik, V., Bailiff, I., Kraus, H., Rodnyi, P., & Ninkovic, J. (2004). Two-photon excitation and luminescence of a CaWO4 scintillator. Radiation Measurements, 38(4-6), 585-588. https://doi.org/10.1016/j.radmeas.2004.02.015

Luminescence of a CaWO4 scintillator was studied in the temperature range 77–500 K using intense laser excitation in the 450–600 nm spectral region. Characteristics of the observed blue emission are similar to those of the intrinsic luminescence of c... Read More about Two-photon excitation and luminescence of a CaWO4 scintillator.
