PpEPFL, the Swiss Federal Institute of Technology in Lausanne, is one of the most dynamic university campuses in Europe and ranks among the top 20 universities worldwide. The EPFL employs more than 6,500 people supporting the three main missions of the institutions: education, research and innovation. The EPFL campus offers an exceptional working environment at the heart of a community of more than 18,500 people, including over 14,000 students and 4,000 researchers from more than 120 different countries. /p h3PhD student position - Long- and short- range structure in electrolyte solutions /h3 h3Mission /h3 pWe are offering a challenging position as a full-time (100%) PhD Student at School of Engineering - STI at EPFL. At the Laboratory for fundamental BioPhotonics - LBP we are developing nonlinear imaging techniques to study, characterize and image water in different configuration. /p h3Introduction /h3 pElectrolyte solutions in water are an essential ingredient of many aspects of life and technology: the bodily fluids (blood and cellular fluid are prime examples), but also are the key contents of batteries. The electrolyte in batteries determines the power output, life span and efficient energy storage. Electrolyte solutions are commonly described as homogeneous mixtures in which ions are statistically distributed. However, it is well known from theoretical considerations in the 1930’s that this simple description is incomplete for the relevant concentration range and that the structure of electrolyte solutions is far more complex. Experiments to understand this need to cover time scales ranging from femto- to milliseconds, and length scales from atomistic dimensions to microns, a huge challenge. /p h3The Project at EPFL /h3 pWe will use various novel home‑built technologies based on nonlinear optical scattering and imaging methods to achieve this: second harmonic imaging, angle‑resolved‑second harmonic scattering, and correlated vibrational spectroscopy, all ultrafast optical methods, supplemented by standard linear spectroscopy and light scattering methods. These methods will be applied to simple 3D electrolytes in water, and 2D electrolyte regions at aqueous interfaces. Linking all datasets will allow to map both short – and long‑range interactions and collective effects pertaining to all molecular actors. This allows to solve the puzzle surrounding concentrated electrolyte solutions and how they work, for example in their charge transmitting/storing functions and lead to a better understanding, and ultimately new technology. /p h3Main duties and responsibilities /h3 ul liHave full responsibility for your own dissertation /li liResearch in close collaboration with industry partners /li liExperiment design and execution /li liAnalyze and interpret experimental results /li liWrite scientific articles for publication in peer‑reviewed journals /li liPresent at international conferences /li liParticipate in education and supervise student project /li /ul pThis research has many interdisciplinary aspects that demand a highly motivated candidate with strong analytical abilities that can think out of the box.
