Surface Science – Surfaces and Interfaces in Environmental Nanotechnology (SIeN)

Dr. Espinosa-Marzal’s lab aims to understand  the fundamentals of soft matter interfaces required to design novel materials and interfaces for a wide range of applications in technology and medicine and motivated by the grand challenges in engineering, specifically those related to engineering better medicine, clean water access and energy storage technologies for sustainable energy sources. Soft matter includes liquids, colloids, polymers, gels, granular materials, and biological materials. For example, soft matter interfaces play an important role in life as it affects the functionality of cell membranes, they are essential for nanomedicine, and they play a significant role in global climate change through precipitation of CO2-binding carbonates in pores and cracks, geomorphological processes of the Earth’s crust, and earthquakes, and even in mineralization within organisms and in man-made enhanced oil recovery. Furthermore, future resources for the water and energy needs of our society, such as supercapacitors for energy storage and water desalination by nanofiltration membranes, rely significantly on the behavior of liquids in nanopores. Motivated by the global challenges of water, energy and health, Dr. Espinosa-Marzal’s research group aims to determine how the properties of soft matter change at interfaces and under nanoconfinement and to elucidate the physical, chemical and mechanical principles that dictate such modified behavior. Understanding the response of these systems is essential in many areas of research including design of biomaterials, fluid engineering, tribology and lubrication, energy storage, water nanofiltration, environmental chemistry, and other separation techniques, as well as for the optimized design of nanomaterials and in geophysics and geochemistry.

The fundamental areas of  research are following:

  • Surface forces
  • Electrical double layer (e.g. on graphene, in ionic liquids, in nanofiltration membranes)
  • Structural and dynamic properties of nanoconfined fluids
  • Biomineralization pathways
  • Lubrication mechanisms of soft matter, friction and adhesion
  • Mechano- and tribochemical processes at mineral-solution interfaces
  • Surface functionalization

The ultimate goal is to understand how to exploit intermolecular interactions to tailor macroscopic properties. The current research targets both to answer fundamental and scientifically relevant questions and to solve problems that are relevant to applications.
