Description:: Plasmonic nanostructures are capable of trapping and confining light at the nanoscale, leading to interesting optical phenomena involving enhanced light-matter interactions. These responses arise in two forms: surface plasmon polaritons propagating on the surface of metal films and localized surface plasmons confined to the surface of metal nanoparticles. Plasmonic modes...

Description:: Two-dimensional materials’ “all-surface” architecture presents a new paradigm for investigations into electron confinement effects and surface phenomena. However, synthesizing, characterizing, and ultimately engineering the properties of 2D materials represents a formidable challenge. This thesis presents several cases of isolating novel 2D materials via vapor-based syntheses. Vapor-based syntheses allow for reproducible...

Description:: Porous metal structures exhibit numerous advantages over dense materials due to their high specific stiffness, strength, damping, energy absorption, and surface areas, making them suitable for applications ranging from actuators to medical implants. However, traditional foam manufacturing methods do not provide sufficient control of the foam micro-architectures, and the creation...

Description:: Gels are three-dimensional polymer networks capable of absorbing a large amount of solvent molecules subject to various external stimuli (pH, temperature, light, etc.). They exhibit a rich mechanical behavior and prominent nonlinearity owing to their high flexibility, stimuli-responsiveness and superabsorbency. More compelling are the intriguing morphologies and novel functionalities achieved...
