About the position

It is well known that small particles can get trapped at the interface between two fluids. This effect can be used to coat droplets with micro or nano-scale particles, and thereby stabilize emulsions without the use of surfactant molecules, known as Pickering emulsions.

Would you like to start your career in a European training network of leading research universities and professionals from the industry? Then you might be interested in this PhD position, which will enable you to join the PICKFOOD project. PICKFOOD is a top-level interdisciplinary training and research programme involving 15 PhD positions across physics, physical chemistry and food science. PICKFOOD aims to create at European level a network of next generation young scientists trained in novel methodologies within Pickering emulsions research enabling the development of safe, healthy and functional foods and at the same time minimizing food waste due to lipid oxidation.

This network is detailed on the site www.pickfood.eu

In the PICKFOOD project NTNU has three PhD vacancies working in the area of experimental soft matter science in the Soft and Complex Matter Lab located at the Department of Physics, Faculty of Natural Sciences, Norwegian University of Science and Technology – NTNU in Trondheim Norway. The 13 other Pickfood positions are advertised through the EURAXESS portal.

About Pickfood position #6 located at NTNU:

Title: Structural development of Pickering emulsions during electric field manipulation and spraying

The current project is to form and characterize Pickering emulsions - particularly food grade Pickering emulsions- under electric fields and upon spraying and other methods to form Pickering emulsion films. This project will use various X-ray and neutron based methods and other methods to characterize structural development of Pickering emulsions under electric field and when sprayed. Particular attention is based X-ray based characterization in situ. The PhD project will elaborate phase behaviour and film formation of Pickering emulsions under electric fields and upon spraying. The project will also screen associated safety and food safety aspects. This project will train the candidate on Pickering emulsions and how they behave in external fields. It will also train the candidate in neutron and X-ray scattering and other methods.

The NTNU workplace of the PhD candidate will be in the Soft and Complex Matter Lab (http://www.softcomlab.com) in certain cases supported by the NTNU Nanolab (https://www.ntnu.edu/nano).

Experimental methods that may be utilized in the project are microscopy (optical, atomic force - AFM, electron (SEM, TEM)) and microfluidic methods. Custom made experiments, such as special purpose sample cells will be designed and built with the help of the laboratory’s technical staff, the NTNU mechanical workshop or by own 3D printing.  The methods also include X-ray scattering characterization both in the Soft and Complex Matter Lab at NTNU and at international synchrotron X-ray facilities. Neutron scattering experiments (SANS or spectroscopy) may be performed by the team at international neutron facilities, such as ISIS UK.

The position has duration of 3 years.

Staring date for employment in the position is January 1 2022.

You will report to Head of Department of Physics Professor Erik Wahlstrøm.

Dr. Matti Knaapila from the Department of Physics will be the main supervisor of the PhD candidate, and Professor Jon Otto Fossum and Professor Paul Dommersnes (Department of Physics) will be co-supervisors at NTNU. Supervision at IFE will be conducted by Geir Helgesen and Kenneth Knudsen; at ETH Zürich by Lucio Isa (Department of Materials) and at FVST by Hanne Boskov Hansen

Duties of the position

Sample preparation that involves physical chemistry for nano-/micro-particle functionalization in the Soft and Complex Matter Lab at NTNU. Some sample preparation in situ will be conducted at international synchrotron facilities.

Characterization of so prepared samples - particularly food grade Pickering emulsions- under electric fields and upon spraying.This should be done by using various X-ray and neutron based methods and other methods and advanced AFM methods focusing on structural development under electric field and when sprayed. Particular attention should be placed on X-ray based characterization in situ. 

Screening of associated safety and food safety aspects. 

Altogether up to 4 months of the employment period will be spent on secondments at scientific partner institutions Institute for Energy Technology (Kjeller, Norway) for advanced analysis of Pickering emulsions using combinations of neutrons and X-rays and Eidgenössische Technische Hochschole (ETH) Zúrich (Zürich, Switzerland) to combine neutron and X-ray scattering to atomic force based techniques to measure the contact angles of individual solid particles at oil-water interface. Up to 3 months will be spend at Danish Veterinary and Food Administration (FVST) involving training in the EU regulations regarding Novel Food and nano materials. This part will look into risk management and whether Pickering particles can be categorized as nano materials or not.

Information about eligibility

The applicant shall, at the time of recruitment by NTNU, be in the first four years (full-time equivalent research experience) of their research careers and not yet have been awarded a doctoral degree. Full-time equivalent research experience is measured from the date when a researcher obtained the degree which would formally entitle him or her to embark on a doctorate, either in the country in which the degree was obtained or in the country in which the researcher is recruited.

The applicant is required to undertake transnational mobility (i.e. move from one country to another) when taking up his/her appointment. At the time of recruitment by NTNU, the applicant must not have resided or carried out his/her main activity (work, studies, etc.) in the country of their host beneficiary for more than 12 months in the 3 years immediately prior to the reference date. Note that the mobility rule applies to Norway, where the researcher is recruited, and not to co-hosting research groups to which the researcher is sent or seconded.

Required selection criteria

  • The PhD candidate position's main objective is to qualify for work in research positions. The qualification requirement is that you at the start of your appointment have completed a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in physics, nanotechnology, materials science, or another relevant field with sufficient physics contents or equivalent education with a grade of B or better in terms of NTNU’s grading scale. If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you are unable to meet these criteria you may be considered only if you can document that you are particularly suitable for education leading to a PhD degree.
  • You must meet the requirements for admission to the faculty's doctoral program (https://www.ntnu.no/fysikk/phd)

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant  

Preferred selection criteria

  • The position requires a strong interest in developing experimental skills.
  • The position requires skills in scientific programming by Matlab / Python.
  • Experience with, or courses in materials physics, experimental physics or physical chemistry, such as in using some of the methods listed above, may be considered an advantage.
  • Good written and oral English.

Personal characteristics

  • Creative, with a strong ability to work goal-oriented.
  • Good skills to deliver oral and written presentations of research results.
  • He/she should also enjoy interdisciplinary research and take keen interest in learning and working in teams, which is of particular importance in this collaborative project.
