Fall Semester, 2014 Research Symposium

 

Trainees were grouped based upon areas of expertise, advisors and time in the IGERT-MNM program.  Group 1 worked under the direction of Drs. Noginova and Pradhan from NSU and Dr. Liddell-Watson from Cornell, with Senior Trainees Sonny Penterman from Cornell and Rabia Hussain from NSU and Junior Trainees Irving Cashwell and Kevin Tanyi from NSU.  Their project, entitled “Assembly and Characterization of Fullerene Microcrystal Structures”, involves fabrication of anisotropic colloidal fullerene microcrystals to serve as the building blocks for a self-assembling monolayer of photonic crystal arrays.  Potential applications:  Solar cells and photosensors.

Group 2 embraced a biomedically-based project with assistance from Drs. Yoon and Pradhan from NSU and Dr. Shepherd from Cornell.  Senior Trainee T. J. Wallin from Cornell led the student team which included Junior Trainees Monique Farrell, Min Hyuck Kim and Donovan Thomas from NSU.  The title of this project, “Development of a Bladder Control System Using a Closed-Loop Feedback”, aims to address the bladder problems of individuals who experience spinal cord injury.  The proposed mechanisms include development of a sensor using fNIR spectroscopy, a control unit for creation of a magnetic field intended to act upon synthesized magnetic nanoparticles incorporated into an implantable, soft robotic actuator, together potentially offering a level of control.

“Synthesis and Optical Characterization of Silver Gyroids” describes Group 3’s research project.  Drs. Bonner and Noginov from NSU and Dr. Wiesner from Cornell directed Senior Trainee Thej Tumkur from NSU and Junior Trainees Kasia Oleske from Cornell and Srujana Prayakarao and Andre Taylor from NSU.  The objective of this group is to fabricate a 3D, bulk, self-assembled metamaterial demonstrating typical negative refraction, high transmission and low reflection, also showing low loss characteristics. Silver was chosen for creating the gyroidal unit.  Applications in the realm of optics include subwavelength imaging and invisibility cloaking.

Group 4 presented research entitled, “High Media Gain Project”, directed by Dr. Wiesner from Cornell and Drs. Noginov and Bonner from NSU.  Vanessa Peters and Thej Tumkur from NSU and Teresa Kao from Cornell offered input as Senior Trainees, and Andre Taylor from NSU contributed as a Junior Trainee.  Attempting to address the problems of high losses and lack of tunability characteristic of currently available metallic/dielectric metamaterials, the goal of this team was to design a non-metallic material with high optical gain.  Hypothesizing that organic dye molecules loaded into silica nanoparticles will exhibit novel optical properties, including this high optical gain, the group proposed to use mC Dots: uniformly-sized, sub-10 nm, single pore silica nanoparticles that may be tuned, as a platform for synthesizing ultra-high dye-loaded nanoparticles for potential use in plasmonic and photonic devices.

The focus of Group 5’s research reflects in the expertise of Dr. Monica Cox from Purdue University’s Engineering Education program, Dr. Suely Black from CMR at NSU, and Senior Trainees Catherine Berdanier and Tasha Zephirin from Purdue.  Entitled “Studying Multi-Institutional Interdisciplinary Research:  Toward a Model for Planning and Evaluating Research Collaborations”, this exploratory study aims to provide insights into ways to plan and evaluate multi-institutional, interdisciplinary science and engineering teams as they establish a research collaboration and begin a research project. Elements of communication and design will be the primary focus, using theoretical frameworks for observing and analyzing data derived from prior literature in a variety of fields.
