- Description:
- Individual plasmonic nanoparticles have the potential to revolutionize all areas of energy science, catalysis, organic electronics, and solar technology. Owing to their light trapping and focusing ability, single nanoparticles can be utilized to efficiently drive chemical reactions at the sub-nanometer scale. Much of the fundamental science regarding how plasmons can...

- Description:
- Systems of colloids coated with high-information polymers are powerful tools for designing crystal lattice with tailorable properties or studying the fundamentals of crystallization. By changing the colloid-colloid interaction strength or colloid shape, different types of lattices can be assembled. In this thesis, I present novel coarse-grained models to describe high-information...

- Description:
- Biopolymers are polymers synthesized by living organisms. Depending on the monomeric units, biopolymers can be classified as polynucleotides (e.g., DNA and RNA), polypeptides (e.g., protein), polysaccharides (e.g., cellulose) and so on. Biopolymers not only play an essential role in nature, but also have wide applications in various fields of industry...

- Description:
- In his Nobel lecture Herbert Kroemer famously stated that “The interface is the device”. While he made this statement in the context of semiconducting heterostructures, it has proven to be just as relevant for more complex materials, such as the transition metal oxides. In particular, the 2-D conducting gas that...

- Description:
- Optical quantum communication (QC) has the potential to address the demands of high-speed and maximally-secure communication. In optical QC, information is encoded onto the state of photons. By using entangled photonic states, QC protocols can support fundamentally secure communication for applications which cannot use classical information. To increase the information...
