PhD in Laser-based nano-texturing of graphene coated membranes

Project Description

As partner on a H2020 project, DCU has secured funding for a four-year project to advance the nano-structuring of surfaces for and membranes and their application to offer material solutions to address Sustainable Development Goals resulting in a positive manner for the society and industrial partners.Specifically, this
project involves the development, implementation, and characterisation of laser machining
techniques for nano-machining and nano-patterning of surfaces and membranes of different
material types. Wear in engineering systems is one of the largest costs in the maintenance of
engineered systems. The application of laser surface texturing can reduced friction and wear
within engineering equipment including within bearings, pistons, gears, and rock drills
Building on an advanced laser system already implemented at DCU, the PhD student will input
into the design and implementation of the advanced laser processing techniques of Laser
Induced Periodic Surface Structuring (LIPSS) and Optical Wavefront Shaping (OWS). The
system will be developed, commissioned and characterised without this project and applied
for various industrial partner applications. One focus of this project will be the nano-structuring
of membrane surfaces which have been coated in graphene / graphene oxide or other 2Dmaterials.
A roll to roll system will be integrated within the laser texturing facility to allow for
the upscaling of laser surface texturing. Industrial applications include sectors such as water
purification, cavitation control, increased efficiency and lifetime of engineering motion

Funding Notes

Applicants should have a Bachelor’s or Masters of Engineering/Science in mechanical
engineering, physics or a cognate field. Experience of mechatronic engineering equipment
systems building and control. A strong background in optics and / or laser machining will be
The team is looking for high performance aspiring applicants with a desire to discovering new
knowledge and to drive advances in the field of materials processing. Applicants are invited
from high achieving graduates with the specific related backgrounds noted above.
