Welcome to the npl homepage

NPL Researcher, Dr Rajani Vijayaraghavan has recently won the Best Poster award at the 21st International Conference on Advances in Materials & Processing Technologies (AMPT 2018), Dublin, 4-7 Sept.2018.  The poster entitled "Controlled growth of single to few layer graphene films with excellent anticoagulation properties: temperature plays a key role" was authored by Rajani K. Vijayaraghavan, C. Gaman, B. Jose, A. McCoy, P.J. McNally and S. Daniels. More details on http://ampt2018.org/

Commencing January 2018, Prof Patrick McNally has been appointed Deputy Editor-in-Chief of Journal of Materials Science: Materials in Electronics. Published by Springer, with an impact factor ca. 2.0, JMSE is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics covering the ground between the fundamental science, such as semiconductor physics, and work concerned solely with applications. It features not only the growth and preparation of new materials, but also their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterisation related to the whole range of applications in electronics.

announced (May 2017) the funding of four new SFI Research Centres including the "Innovative techniques and processes in Additive Manufacturing" centre, called I-Form.  NPL researchers have been funded under I-Form, and will provide novel non-destructive radio frequency, x-ray and photoacoustic metrologies for additive manufacturing process quality monitoring. Prof Patrick McNally will be working with the I-Form Deputy Director, Prof Dermot Brabazon of APT, on developing and validating these new technologies in a processing environment. More details on www.i-form.ie

Exciting novel nondestructive x-ray diffraction imaging techniques have been pioneered by the Dublin-Durham-Freiburg research team led by Prof Patrick McNally of NPL and has been publicised as a Science Highlight by the Diamond Light Source in Oxfordshire (UK), one of Europe's largest and most advanced research facilities. Using the intense x-ray beams generated at Diamond, the team has developed a suite of techniques capable of accurately, precisely and verifiably measuring the stress and warpage in silicon die inside fully encapsulated advanced chip packages. These packages are under development for next generation integrated circuit deployment and the work points the way to a new industry based quality assurance technique.  Further details are available on


Enterprise Ireland has recently awarded a Commercialisation Fund Award to NPL for the 30 month development of novel technology for radio frequency monitoring of commercial plasma processing systems. The project is entitled "Non-invasive Monitoring Probes for Industrial Plasmas (NiMPIP)" and builds on earlier Enterprise Ireland support via their Commercial Case Feasibility programme.


Dr Stephen Daniels of NPL was awarded a Health Research Board & Science Foundation Ireland research grant under the Translational Research Awards programme. This project is entitled "Improved Methods to Detect and Decontaminate Environmental Sources of Healthcare-Associated Infection" and runs in collaboration with Professor Hilary Humphreys in RCSI/Beaumont Hospital, Dublin.
