Materials and Nanoscience is a very strong program at UCLA, and it spans a wide range of research areas, including nanomaterials, materials, inorganic materials, and biomaterials.

We produce and study nanoscale architectures for applications in nanoelectronics, nanophotonics, nanomagnitics, and even as novel mechanical materials.

Our work in nanostructured materials takes advantage of strong collaborations with the California NanoSystems Institute (CNSI). Our sample work includes:

  • self-organized nanoscale materials (Tolbert)
  • control of surfaces and interfaces (Gimzewski)
  • sol-gel derived materials (Zink)
  • lithographically produced nano-materials (Baugh)

Work in the area of Materials and polymeric materials is also quite varied and spans the field from electronic polymers to polymer emulsions. Some specific areas of expertise include:

Finally, the materials effort interfaces with our strength in bio-physical chemistry in the use of nanoscale materials as optical probes (Weiss).

The materials emphasis in physical chemistry is complemented by the strength in synthetic materials throughout the department. This includes expertise in:

These research groups are highly collaborative and offer a diverse range of opportunities to combine materials physical chemistry, materials processing, materials physics, and materials synthesis.

 

At UCLA, our Materials chemistry research can lead to practical applications such as:

  • Superhard Materials
  • Thermoelectric materials
  • Chemical Sensors
  • Creation of new synthetic polymers
  • Memory Devices and High Density Electronics
  • Actuators
  • Transparent Conductors
