Journal Article
Pieris, D., Stratoudaki, T., Javadi, Y., Lukacs, P., Catchpole-Smith, S., Wilcox, P. D., …Clark, M. (2020). Laser Induced Phased Arrays (LIPA) to detect nested features in additively manufactured components. Materials and Design, 187, Article 108412. https://doi.org/10.1016/j.matdes.2019.108412

© 2019 The Authors. Additive manufacturing (AM) has the capability to build complex parts with internal features, which have many advantages over conventionally manufactured parts. This makes AM an alternative for advanced manufacturing sectors. AM c... Read More about Laser Induced Phased Arrays (LIPA) to detect nested features in additively manufactured components.

This report introduces a novel time resolved Brillouin spectrometer, consisting of an opto-acoustic transducer which resides on the tip of a single-mode optical fiber of arbitrary length with 125 µm outer diameter and 5 µm sensing diameter. Demonstra... Read More about Time resolved Brillouin fiber-spectrometer.

Spatially resolved acoustic spectroscopy (SRAS) microstructural imaging (2019)
Presentation / Conference Contribution
Clark, M., Clare, A., Dryburgh, P., Li, W., Patel, R., Pieris, D., …Smith, R. (2019). Spatially resolved acoustic spectroscopy (SRAS) microstructural imaging. AIP Conference Proceedings, 2102, Article 020001. https://doi.org/10.1063/1.5099705

© 2019 Author(s). Spatially resolved acoustic spectroscopy (SRAS) is an acoustic microscopy technique that can image the microstructure and measure the crystallographic orientation of grains or crystals in the material. It works by measuring the velo... Read More about Spatially resolved acoustic spectroscopy (SRAS) microstructural imaging.

Thickness measurement of polymer thin films with high frequency ultrasonic transducers (2019)
Presentation / Conference Contribution

New insights into the mechanical properties of Acanthamoeba castellanii cysts as revealed by phonon microscopy (2019)
Journal Article
Pérez-Cota, F., Smith, R. J., Elsheikha, H. M., & Clark, M. (2019). New insights into the mechanical properties of Acanthamoeba castellanii cysts as revealed by phonon microscopy. Biomedical Optics Express, 10(5), 2399-2408. https://doi.org/10.1364/BOE.10.002399

The single cell eukaryotic protozoan Acanthamoeba castellanii exhibits a remarkable ability to switch from a vegetative trophozoite stage to a cystic form, in response to stressors. This phenotypic switch involves changes in gene expression and synth... Read More about New insights into the mechanical properties of Acanthamoeba castellanii cysts as revealed by phonon microscopy.
