The long term goals of the Triangle MRSEC REU program are to maximize opportunities for undergraduate involvement MRSEC research, recruit diverse undergraduate students from across the country, and encourage and support future careers in materials science and engineering.
Lasing from an electromagnetic hot spot supported by coupled metal nanoparticles (NPs) has been demonstrated for the first time. This new nanolaser architecture is based on three dimensional (3D) Au bowtie NPs supported by an organic gain material.
From drug delivery to catalysis to optoelectronics, the need for efficient fabrication pathways for particles over a wide range of sizes, from a variety of materials, and in many different structures is
Teacher Workshop: Eighteen elementary school teachers participated in summer workshop. Student impact of approximately 200 students.
Discovery: A class of 2D covalent organic framework made of triphenyl- metal compounds are found to be topological insulators exhibiting robust nontrivial topological edge states.
Approach: Predictive First-principles band structure and band topology calculations.
In our system, a colloidal particle (upper left (a), red) is trapped by optical tweezers (upper left (b)) as a surrounding colloidal suspension flows past. Surprisingly, long range order develops in the particle density (lower left, dark bands are regions with over-representation of particles, sigma is the particle diameter).
