9 PhD or postdoc* positions (early stage researchers) in Lubricant Impregnated Slippery Surfaces - LubISS
* At the time of recruitment by the host organization the applicant needs to be in the first four years
of their research careers. Applicants may be on a PhD program but cannot be PhD holders at the day of
signing their employment contract.
We are currently looking for 9 Early Stage Researchers to embark on our three-year program (benefits and
eligibility criteria are listed below). For further details about the PhD positions and the involved scientists,
Textured substrates which are infiltrated with a lubricant form a new class of functional surfaces, referred to as
Lubricant Impregnated Slippery Surfaces (LubISS). Texture is decisive for capillary forces to retain
the lubricant in place a distinctive feature of LubISS is that (water) droplets, ice crystals and microorganisms
slide off these surfaces very easily. Capillary forces also bring about a so-called annular wetting ridge which
surrounds liquid droplets and solid particles. However the latter influences the properties of resting and moving
droplets and can drag lubricant along. Depending on the dominant interactions and forces, droplets can even be
cloaked by a thin layer of lubricant. In order to design durable and environmentally friendly LubISS,
our network strives to understand the interplay between the physical- and chemical interactions, the surface topography,
the lubricating film and the droplet under both static and flow conditions.
LubISS is the first European Training Network with the main objectives of designing, characterizing, and modelling low
adhesive easy-to-clean slippery surfaces for anti-icing and anti-fouling. In a coordinated effort among 9 world-class
academic institutions and industrial partners from 6 European countries (Finland, France, Germany, Great Britain,
Netherlands, Switzerland), advanced lubricant impregnated surfaces will be developed.
In order to design durable and environmentally friendly LubISS, our network strives to understand the interplay between the
physical- and chemical interactions, the surface topography, the lubricating film and the droplet under both static and flow
conditions. We will characterize the dynamics of single droplets but also of two liquids moving over each other. The understanding
of two-phase flow will help to design lubricant impregnated surfaces that don’t suffer from lubricant depletion. If depletion
cannot be avoided, approaches to replenish drained lubricant will be developed. Promising methods to design high end surfaces
include nanoparticle based techniques, nanofibers or thermal spraying. We will investigate the wear resistance of the surfaces
and their performance as icephobic coatings for aerospace applications. Ice and wind tunnels are available. Furthermore, we
will quantify the adhesion of bacteria and other microorganisms on impregnated surfaces, making use of the combination well
adapted surface functionalization and microstructuring.

ESR (early stage researcher) shall at the time of recruitment by the host organization be in the first four years of their research careers.
Applicants may be on a PhD program but cannot be PhD holders at the day of signing their employment contract.
The position is open to applicants of all nationalities provided that the European Commission's Mobility Rule is
satisfied: "At the time of recruitment by the host organization, researchers must not have resided or carried out their
main activity (work, studies, etc.) in the country of their host organization for more than 12 months in the 3 years
immediately prior to the reference date. Short stays such as holidays and/or compulsory national service are not taken
Maximum and preferred period of employment: 36 months
The project provides full funding for tuitions fees and salary.
The successful candidate will receive:
Living allowance (multiplied by the country correction factor which varies between 0.98 and 1.2): 3110 euros per month.
Mobility allowance: 600 euros per month.
Family allowance (if applicable): 500 euros per month.
What we expect
Potential candidates must have an excellent Master (or equivalent) in physics, chemistry, or engineering. Beyond the passion for and
experience in research, we expect good language and communication skills in English, flexibility as well as focused research.
What we offer
Our program aims to provide young researchers with excellent cross-disciplinary education in
fundamental and practical concepts in physical and chemical surface science
management, communication and mentorship skills required to become future leaders in academics or industry.
The training program of the LubISS network comprises five elements:
(i) Individual Training and Supervision Plan
(ii) Local training activities at the host institutes
(iii) Inter-sectorial secondments and ESRs exchange
(iv) Network-wide training events
(v) Overarching workshops on soft, technical and methodical training.
