PhD Candidate in Advanced Synthesis of Lubricant Additives


We have a vacancy for a PhD Candidate at Department of Mechanical and Industrial Engineering (MTP) in synthesis of lubricant additives based on ionic liquids. We are looking for candidates with a background in one or ideally more of these areas: organic chemistry, tribology, experimental physics, chemical engineering, materials science.

Lubrication is a complex problem with many different physical and chemical processes occurring on different length scales. Lubricants are used for achieving the required level of friction and wear rates in moving systems, keeping low wear, controlling friction, minimizing energy losses, etc. A lubricant consists of base fluid and additive package (AP), which is the component in the lowest proportion (1-30%) providing the functionalities to the base fluid. The AP is a complex mixture of chemical compounds having a direct impact on the environment due to leakages and poor recycling methods. Additives radically change the properties of lubricants. Additives are a mixture of many different chemicals covering several functional categories such as friction modifiers, anti-wear and/or extreme-pressure additives, antioxidants, dispersants, viscosity modifiers, anti-corrosion, anti-foaming, pourpoint depressants, etc. Every function of an additive is fulfilled by single chemicals carefully designed to avoid competition with each other.

This PhD position has the goal of developing new multifunctional additives to reduce the number of chemicals simplifying lubricant formulations and production methods making the recycling processes easier and affordable for producers, users and policy makers. Achieving this goal will bring forward the green and sustainable goals Europe has set for the future of our economy and our environment. We are looking for a PhD candidate able to synthetize and test the new substances we have in mind for this project.

About the Materials Group

The Materials Group deals with applications of materials science: engineering materials and surfaces with desirable properties for specific applications. The group consists of an interdisciplinary mixture of engineers, physicists, and chemists. We have many industrial and international academic collaborations and aim to provide a stimulating environment for young scientists.


You will report to Professor Nuria Espallargas

Duties of the position

Synthetise complex ionic liquid molecules.

Formulate lubricants assuring proper dispersibility of the ingredients.

Test the functionality of the ionic liquids in a tribology context.

Test the functionality of the ionic liquids in a nano-context (surface adsorption).

Conduct independent research and publish the results in recognised scientific journals.

Required selection criteria

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is that you have completed a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in chemistry, chemical engineering, mechanical engineering, materials engineering, experimental physics or equivalent education with a grade of B or better in terms of NTNU’s grading scale.

The period of employment is 3 years.

Appointment to a PhD position requires that you are admitted to the PhD programme in Engineering,,  within three months of employment, and that you participate in an organized PhD programme during the employment period.

The engagement is to be made in accordance with the regulations in force concerning State Employees and Civil Servants, and the acts relating to Control of the Export of Strategic Goods, Services and Technology. Candidates who by assessment of the application and attachment are seen to conflict with the criteria in the latter law will be prohibited from recruitment to NTNU. After the appointment you must assume that there may be changes in the area of work.

The position is subject to external funding. 

It is a prerequisite you can be present at and accessible to the institution daily.

About the application

The application and supporting documentation to be used as the basis for the assessment must be in English.

Publications and other scientific work must follow the application. Please note that applications are only evaluated based on the information available on the application deadline. You should ensure that your application shows clearly how your skills and experience meet the criteria which are set out above. 

The application must include:

Motivation letter explaining why you think you are the perfect match for the position

CV, certificates and diplomas

Name and address of three referees

Joint works will be considered. If it is difficult to identify your contribution to joint works, you must attach a brief description of your participation.

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability.

NTNU is committed to following evaluation criteria for research quality according to The San Francisco Declaration on Research Assessment - DORA.

General information

Working at NTNU

A good work environment is characterized by diversity. We encourage qualified candidates to apply, regardless of their gender, functional capacity or cultural background. 

The city of Trondheim is a modern European city with a rich cultural scene. Trondheim is the innovation capital of Norway with a population of 200,000. The Norwegian welfare state, including healthcare, schools, kindergartens and overall equality, is probably the best of its kind in the world. Professional subsidized day-care for children is easily available. Furthermore, Trondheim offers great opportunities for education (including international schools) and possibilities to enjoy nature, culture and family life and has low crime rates and clean air quality.

As an employee at NTNU, you must at all times adhere to the changes that the development in the subject entails and the organizational changes that are adopted.

In accordance with The Public Information Act (Offentleglova), your name, age, position and municipality may be made public even if you have requested not to have your name entered on the list of applicants.

If you have any questions about the position, please contact Professor Nuria Espallargas, email:

Please submit your application electronically via with your CV, diplomas and certificates. Applications submitted elsewhere will not be considered. Diploma Supplement is required to attach for European Master Diplomas outside Norway. Chinese applicants are required to provide confirmation of Master Diploma from China Credentials Verification (CHSI).

If you are invited for interview you must include certified copies of transcripts and reference letters. Please refer to the application number IV-120/21 when applying.
