5 Minutes With...Juliane Benedet, MechEng PhD Student, Imperial College London
I employed a multi-technique approach, i.e. MTM-SLIM, MTM-Reciprocating, AFM, FIB-SIMS, FIB-TEM, ToF-SIMS and XANES, in order to determine which classes of lubricant additive types are able to form protective boundary films that reduce wear and friction in rubbing contacts. This study benefits designers of the next generation of engine lubricants and also helps us understand at a more fundamental level the various ways that lubricants can control wear in boundary lubrication conditions.
What recommendations would you give to other students and researchers in the field? Although very rewarding, research can also be quite lonesome sometimes, so try to have perseverance, keep a close eye on the details and ask for help or a second opinion.
Tribologists and tribologists-to-be: don’t mind if most people have no idea what Tribology is. There are endless examples of “tribology-at-work” from cars and machines to joint replacements, food and hair products. No matter how much you try to explain, some people will still look puzzled and either say you are brainy or make a few lubrication-related jokes, don’t worry you can always count on your fellow tribologists.
What are some of your favorites?
Tribology/Mechanical Engineering book: Engineering Tribology by Gwidon Stachowiak and Andrew Batchelor
Professor: Professor Hugh Spikes, for his invaluable support, insights and encouragement throughout my PhD.

Interests: Because I am of Italian-Brazilian descent I have inherited a passion for food and cooking so I spend my free time trying new recipes and entertaining my good friends and family.
Juliane has received her Bachelor degree in Chemical Engineering in 2005, from the University of Southern Santa Catarina in Brazil, where she worked for the National Service for Industrial Training (SENAI, 1998-2005) in the investigation, optimization and knowledge transfer of rheological aspects of ceramic suspensions.
She began working in the R&D of additives in 2006 at Infineum UK, where she investigated lubricity and detergency improvers for diesel fuels, afterwards joining Castrol Ltd in 2007 to investigate the thermal stability of lubricating oils. She briefly re-joined Infineum in 2011 as a Power Transmission Fluid Technologist, responsible for proposing technical solutions to fluid related hardware issues.
Currently, she is a PhD student in the Tribology Group of the Mechanical Engineering Department at Imperial College London, where she has investigated the film-forming, friction and wear-reducing properties of a very wide range of alternative low and zero sulphated ash, phosphorus and sulphur (SAPS) antiwear additives of different chemical types to improve the next generation of engine oils and extend the life of vehicle exhaust aftertreatment systems.
