Career overview

Since obtaining his PhD from the School of Chemistry, University of Birmingham (Thesis title: Utilization of nanostructured surfaces for sensing applications and the use of nanoentities for the fabrication of new materials; supervisor: Professor Jon Preece) Dr Hamlett held postdoctoral research positions in the School of Science and Technology between November 2009 and November 2014. He has worked with Professor Glen McHale and Dr Mike Newton on a collaborative project with geographers from Swansea University investigating the role of hydrophobicity and particle size on the enhanced erosion of naturally water repellent soils.

He has also worked on an EPSRC Platform Grant with Professor Glen McHale and Dr Mike Newton on the development and application of superhydrophobic surfaces. During his time on the platform grant, Dr Hamlett organised and led a team to represent Nature's Raincoats at Techfest 2012 in Mumbai and worked on controlling the wettability of standard photolithographic polymers by controlling the surface chemistry of glass inclusions.

Dr Hamlett has also worked as a postdoctoral research fellow, with Dr David Fairhurst and Professor John Wallis, on an industrially funded project investigating new molecules to use to make foams for firefighting. During this role he supervised a summer research student on a project concerned with bubble blowing and visited Laborastoire de Physiques des Solides (Paris, France) to measure the effect of a variety of additives on the rheology of model surfactant and protein solutions.

Dr Hamlett has been responsible for the thin film laboratory in the Erasmus Darwin building and regularly assists with the Nature's Raincoats' exhibit at public science fairs and events and has delivered additional sessions as a STEMNET ambassador. Dr Hamlett has also taught on the undergraduate Physics module entitled Radiations and Non-Invasive Imaging (Module PHYS22211).

Research areas

Dr Hamlett's current research is concerned with the control of the chemistry and topography of solid surfaces and the influence that both factors have on the properties of the solid in terms of its wettability and chemical immobilisation. Such applications include the control of foams generated from surfactant solutions and making stain resistant 3D printed objects.

His previous postdoctoral research positions include an industrially-sponsored project that was concerned with the development of new fluorine-free foams for firefighting. He has also worked on projects concerning superhydrophobicity including the implications of water repellency in soil systems and lichens, the development of new water repellent surfaces for sensor devices and fabrics and new methodologies for the fabrication of superhydrophobic surfaces.

Dr Hamlett also has experience in a range of analytical techniques including:

  • contact angle goniometry
  • surface tension measurements (Du Nouy ring and pendant droplet methods)
  • elipsometry
  • profilometry
  • atomic force microscopy (AFM)
  • scanning electron microscopy (SEM)
  • transmission electron microscopy (TEM)
  • x-ray photoelectron spectroscopy (XPS)
  • high speed videography
  • molarity of ethanol droplet (MED) tests.

He has experience of a number of preparative techniques including chemical modification using liquid and vapour phase techniques, nanoparticle synthesis, photolithography, microcontact printing (soft lithography) and foam generation.

Opportunities to carry out postgraduate research towards an MPhil / PhD exist and further information may be obtained from the NTU Graduate School.
