Nano and Molecular Systems Research Unit (NANOMO)

Faculty of Science 

NANOMO research unit is an international research environment and active collective of researchers with wide range of experimental, theoretical and computational interests in nanomaterials, functional materials, atmospheric research, quantum simulations and computing, materials characteri-zation methods, biomedical physics and physics didactics. A major part of the experimental research focuses on activities at international synchrotron radiation facilities. 

Research topics:

  • Localization and dissipation in arrays of superconducting qubits. We are interested in the condensed matter aspects of large arrays of superconducting qubits. Specifically, how does disorder, dissipation or measurements affect different quantum phase transitions realized with these so-called superconducting quantum simulators. We combine analytical, computational and through collaborations also experimental methods.
  • Physics of ultrahigh strength alloys. The needs of modern alloys are everywhere. Despite engineering efforts, physical driving force of alloy for-mations and microstructural evolution mechanisms remains elusive. Engaged with high brilliance synchrotron and in situ characterizations, we grasp the first hand spectromicroscopic signatures of alloying and phase transformation, elucidate them with help from density functional calculations, and deduce their physical mechanisms. In turn, knowledge obtained will promote alloy realizations for tailored applications.
  • Probing charge transfers in semiconductor photocatalysis. Redox happening in photocatalysis is originated from charge transfers among reagents and catalysts. Directing charge transfers offer a unique shortcut in catalyst design and catalytic ability promotion. Here, we apply various synthesis, in house and synchrotron characterizations, and first-principles calculations to probe and direct charge transfers in semiconductor photocatalysts for hydrogen evolution and water purification.   
  • Surface structure and composition of nanoparticles. Soft X-ray photoelectron spectroscopy is a powerful technique to study the surface properties of nanoparticles. Owing to the very short escape depth of the photoelectrons, they carry information only from the first monolayers. In this work, we focus on surface structure of free-flying nanoparticles, mostly studied using synchrotron radiation excited photoelectron and –ion spectroscopies, but complementary techniques like electron microscopy can be used as well. The samples can vary from metal nanoparticles to in situ generated aerosols, and they can be exposed to different environmental parameters (heat, oxidants, humidity…). We are looking for a candidate with experience in X-ray spectroscopy and/or high vacuum instrumentation to carry out experiments and participate to sample delivery system development.
  • X-ray spectromicroscopy. We have a new emerging line of research in the NANOMO research unit, spectromicroscopy and tomographic imaging of biological samples and inorganic materials in collaboration with research groups from medical and technical fields. We are looking for a candidate with experience in X-ray imaging and/or spectroscopy to carry out spectromicroscopic experiments, sample environment development and related data analysis.
