Journal Article
Al-Jarwany, Q. A., Mohammed, A. F., Hamza, A. O., Bouillard, J. S., Adawi, A. M., Pamme, N., & Walton, C. D. (2020). Realisation of a sub-wavelength dimple using a 193 nm wavelength photonic nano jet. Chemical Physics Letters, 750, Article 137400. https://doi.org/10.1016/j.cplett.2020.137400

There are many areas of research that benefit from tight focussing of light. We report experimental and computational results of a laser irradiated silica microsphere, 1 μm diameter localised on an SU-8 substrate. A single pulse from an ArF excimer l...

Photothermal colloid antibodies for shape-selective recognition and killing of microorganisms (2013)
Journal Article
Borovička, J., Metheringham, W. J., Madden, L. A., Walton, C. D., Stoyanov, S. D., & Paunov, V. N. (2013). Photothermal colloid antibodies for shape-selective recognition and killing of microorganisms. Journal of the American Chemical Society, 135(14), 5282-5285. https://doi.org/10.1021/ja400781f

We have developed a class of selective antimicrobial agents based on the recognition of the shape and size of the bacterial cells. These agents are anisotropic colloid particles fabricated as negative replicas of the target cells which involve templa...

Inscription of fibre Bragg gratings in non-sensitised fibres using VUV F2 laser radiation (2008)
Journal Article
Dyer, P. E., Johnson, A. M., & Walton, C. D. (2008). Inscription of fibre Bragg gratings in non-sensitised fibres using VUV F2 laser radiation. Optics express, 16(23), 19297-19303. https://doi.org/10.1364/OE.16.019297

We report the inscription of fibre Bragg gratings in non-sensitised SMF 28 and HI 980 fibre by exposure to VUV F2 laser radiation at 157nm. The modulated effective refractive index change Δneff deduced from the shift in the grating reflection peaks w...

Ionization in vacuum ultraviolet F2 laser ablated polymer plumes (2007)
Journal Article
Dyer, P. E., Pervolaraki, M., Walton, C. D., Lippert, T., Kuhnke, M., & Wokaun, A. (2008). Ionization in vacuum ultraviolet F2 laser ablated polymer plumes. Applied physics. A, Materials science & processing, 90(3), 403-409. https://doi.org/10.1007/s00339-007-4341-x

An experimental investigation of ion generation in the 157-nm vacuum ultraviolet (VUV) F-2 laser ablation of three selected polymers - glycidyl azide polymer (GAP), a triazene polymer (TP6) and polyimide - is described. An ion collector probe is used... Read More about Ionization in vacuum ultraviolet F2 laser ablated polymer plumes.
