The Marie Curie Innovative Training Network nanoPaInt offers multiple Early-Stage Researchers (ESRs) interdisciplinary, intersectoral and international training in the frame of PhD positions. The research topics of the projects are related to the behaviour of dense nanosuspensions. The main objectives of the individual research projects include theoretical modeling, experimental characterization, rheological measurements, design of new materials.
The nanoPaInt training programme is in line with the European Charter for Researchers, the Code of Conduct for the Recruitment of Researchers and the EU Principles for Innovative Doctoral Training. Fellows can choose their position among the offers from the academic and non-academic Beneficiaries. ESRs working within industry will be enrolled in a doctoral programme of one of the partaking universities. All fellows will be offered a 3-year employment contract and will start (with some flexibility) in January 2021 or later.
Due to the mobility requirement of the European Commission for ITN projects, we can only accept candidates that have not been working/living in the country of host institution for more than a total of 12 months within the 3 years prior to recruitment date.
Applicants must at the time of recruitment be in the first four years (full-time equivalent) of their research careers. The four years start to count from the date when a researcher obtained the degree (e.g. Master’s degree) which would formally entitle him/her to embark on a doctorate. The applicants must at the time of recruitment have not been awarded a doctoral degree.
Equal opportunities are ensured to all candidates throughout the evaluation process.

Bulk and surface rheology of nanosuspensions under strong mechanical perturbation
Main supervisor: Prof. Ramon G. Rubio, Universidad Complutense de Madrid, Spain
This vacancy is closed!
The overall aim of the project will be to characterize experimentally the bulk and interfacial properties of micro- and nanosuspensions and correlate them with the particle-particle interactions. Rheology, light scattering, frequency-dependent conductimetry, zeta potential and neutron scattering will be the main bulk techniques to be used. Several types of tensiometers, home-made capillary wave techniques, and surface microwire shear equipment will be used for characterizing the interfacial rheology. Part of the work of the Ph.D. student will be to modify the design of the available capillary wave equipments to extend their frequency ranges. Since at high concentrations, typical of commercial products, the dynamics of particles is strongly hindered by the close presence of other particles, the effects of crowding will be studied by combining microfluidics, optical tweezers, particle tracking, and fluorescence correlation microscopy. The outputs of the project, together with those of other groups of the Network, will provide the necessary experimental and theoretical basis to understand the behavior of suspensions and foams of industrial interest. The Ph.D. candidate will do secondments in other laboratories of the Network, and participate in its periodic workshops.

Wetting-dewetting flow in vibrating sessile drop and nanoparticle self-assembly
Main supervisor: Prof. Miguel A. Cabrerizo-Vilchez, University of Granada, Spain
This vacancy is closed!
The ESR will experimentally investigate colloidal self-assembly on solid substrates triggered by mechanical vibration. By vibrating sessile drops of aqueous nanoparticle suspensions, different colloidal patterning on substrates will be found. The ESR will explore the impact of the wetting properties of the substrates (contact angle hysteresis), nanoparticle properties (size, electric charge) and concentration (viscosity) and vibration signal (fast/slow). The interplay between the collective diffusion of nanoparticles, the contact line pinning and the oscillating convective flow driven by vibration will rule the structured nanoparticle arrangement on the substrates. The ESR will use high speed imaging and advanced instrumentation for surface and nanoparticle characterization. The ESR will develop a theoretical background on liquid drop resonance, contact line dynamics and nanoparticle diffusion.
Deposition of nanoparticles during spreading and evaporation of nanofluid drops in the presence of superspreading and non-superspreading trisiloxane surfactants on hydrophobic substrates
Main supervisors: Dr. Joachim Venzmer, Evonik Operations GmbH, Germany, Prof. Tatiana Gambaryan-Roisman, Technische Universität Darmstadt, Germany
This vacancy is closed!
The Early Stage Researcher (ESR) working on the subproject given in the title should use hydrophilic nanoparticles to gain insight into the spreading behavior of different surfactant solutions on hydrophobic substrates. The motivation to these studies is twofold: On the one hand, from the deposition pattern of the nanoparticles after drying one could draw conclusions on the flow pattern within the droplet during the spreading process, and hence gain insight into its mode of action. On the other hand, the results should allow to design formulations which lead to a desired deposition pattern, which is relevant for applications e.g. in agrochemicals. The ESR will be recruited for the first 12 months by Evonik in Essen and for the next 24 months by Technische Unversität Darmstadt.
The position is available starting from January 1, 2021. Applications are invited from candidates with Master degree in Chemical Engineering, Mechanical Engineering, Physical Chemistry, Physics or related fields and having interest in both experimental as well as theoretical work.

Formation of porous supraparticles by evaporation of two coalescing drops on a superamphiphobic substrate
This vacancy is closed!
Main supervisor: Prof. Hans-Jürgen Butt, Max Planck Group, Institute for Polymer Research, Germany
The vision of the project is to fabricate porous supraparticles of precisely defined size (typically 0.1 -1 mm diameter) and morphology by drying drops of a suspensions. To obtain spherical supraparticles the drops are dried on superamphiphobic surfaces. To achieve complex morphologies and thus higher functions we plan to merge two drops of different size and composition prior to full evaporation. A prerequisite is to understand the underlying physical processes. Therefore, the task is to (1) image the drops with high-speed video microscopy, (2) image their dynamic contact line by confocal microscopy, (3) characterize the final supraparticles by electron microscopy and (4) mechanical tests.
We are looking for a physicist, engineer or material scientist with technical skills, who is able to design and modify experimental setups, keen to learn the underlying soft matter physics, interested in designing innovative materials, able to use standard programming, and wishes to work in an international team. We offer excellent equipment, knowhow and supervision.

Development and optimization of inks and 3D printing process of functional nanomaterials and parts
Main supervisors: Prof. Shlomo Magdassi, Dr. Alexander Kamyshny, Hebrew University of Jerusalem, Israel
This vacancy is closed!
The research of ESR (HUJI) will be focused on development and optimization of inks for 2D and 3D printing, for fabrication of objects based on functional nanomaterials.
Several research activities will be performed, among them:
- Inks based on a mixture of ceramic nanoparticles (silica, alumina, and zirconia) and organic medium containing photosensitive polymer or polymerizable monomer, for 3D printing of ceramic objects. The main method, which will be used for 3D fabrication of ceramic objects is stereolithography (SLA). The main field of application is fabrication of 3D objects with enhanced mechanical properties.
- Ink composed of photopolymerizable oligomers and a photoinitiator, the synthesis of the oligomers will be performed by a sol-gel process. Various functional nanoparticles (magnetic, dielectric, etc.) will be added to the ink. 3D printing of sol-gels inks will be mainly performed by laser writing based on two photon polymerization (TPP), to obtain objects with sub-micron resolutions.
- Ink based on hydrogels, which are 3D crosslinked network of hydrophilic polymers which can absorb large amount of water or biological fluids by swelling and can respond to chemical and physical stimuli such as temperature, pressure, pH, ionic strength and magnetic or electric field. The formed hydrogels will be responsive for external stimuli, thus opening possibilities for 4D printing.
