From Graphene to Carbon Fibres: Mechanical Deformation and Development of a Universal Stress Sensor
Otakar Frank, Georgia Tsoukleri, Ibtsam Riaz +6
Carbon fibres (CF) represent a significant volume fraction of modern structural airframes. Embedded into polymer matrices, they provide significant strength and stiffness gains ove…
Compression Behavior of Single-layer Graphene
Otakar Frank, Georgia Tsoukleri, John Parthenios +5
Central to most applications involving monolayer graphene is its mechanical response under various stress states. To date most of the work reported is of theoretical nature and ref…
Colossal photostructural changes in chalcogenide glasses. Athermal photoinduced polymerization in AsxS100-x bulk glasses revealed by near-bandgap Raman scattering
F. Kyriazis, S. N. Yannopoulos
Near-bandgap Raman scattering was used to induce and study photostructural changes in AsxS100-x bulk glasses revealing a new photoinduced polymerization effect. Raman spectra were…
Uniaxial Strain in Graphene by Raman Spectroscopy: G peak splitting, Gruneisen Parameters and Sample Orientation
T. M. G. Mohiuddin, A. Lombardo, R. R. Nair +10
Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality. Since its experimental discovery, graphene continues to attract enormous interes…
Effect of cluster size of chalcogenide glass nanocolloidal solutions on the surface morphology of spin-coated amorphous films
T. Kohoutek, T. Wagner, M. Frumar +3
Amorphous chalcogenide thin film deposition can be achieved by a spin-coating technique from proper solutions of the corresponding glass. Films produced in this way exhibit certain…
Role of defects and disorder in the half-metallic full-Heusler compounds
I. Galanakis, K. Ozdogan, E. Sasioglu
Half-metallic ferromagnets and especially the full-Heusler alloys containing Co are at the center of scientific research due to their potential applications in spintronics. For rea…
