Next generation nanocomposites based on 2D polymers and 2D inorganic materials
Graphene, boron nitride, dichalcogenides and other inorganic 2D layered materials (2DLM) have atomically thin structure with unique electrical, mechanical, thermal, and optical properties, and have already been extensively explored for electronics, sensing, catalysis and biomedical applications. On the other hand, in the polymer world, there is an emerging class of 2D polymers with analog structure to 2D layered materials.
Electrochemical sensors for microbial activities in benthic sediments: a sentry for lacustrine P biogeochemistry
Release of phosphate-P immobilized in benthic sediments poses a remnant threat to induce harmful algal blooms (HAB) despite adequate management of external loads of phosphate. This process, referred to as internal loading of P, is induced by microbially mediated alternations of sediment and porewater chemistry and bacteria that “breath” iron are mostly responsible for controlling the release of P from sediments. We have developed an electrochemical split-chamber zero resistance ammetry (SC-ZRA) technique that we can use to detect microbiological activities.
Sedimentation of heavy particles in sheared soft particle glasses
Soft particle glasses (SPGs) are composed of elastic non-Brownian particles that are jammed beyond the packing fraction of equivalent hard spheres. SPGs show solid-like behavior at rest, and they flow when subjected to external stimuli such as shear deformation. Considering this tunable rheological property, they have been used as additives in many products such as cosmetic creams, hair gels, food products, paper coating industries, and recently it has been suggested that these suspensions can be used in the drilling muds.

Rheological Dynamics of Liquid Crystals under Thermal Gradients
Our group has developed a rheological apparatus capable of sustaining spatial thermal gradients in shear rheometry. It is hypothesized that orthogonally superimposed thermal fields will produce linear, field-averaged rheological responses up to a threshold where anomalous, thermo-rheological dissipative phenomena will occur. The molecular influence of heat flow, especially at reduced dimensions, is from entropy production.
Synthesis and Characterization of (Potentially Novel) Elastomeric Compounds
Our group has recently discovered a material system that potentially may have elastomeric properties. The Internation Union of Pure and Applied Chemistry (IUPAC) defines an elastomer as a polymer that displays rubber-like elasticity, i.e. high viscoelasticity with weak intermolecular forces. We are seeking a highly motivated and ambitious student to assist us in exploring this material system for its potential elastomeric properties and to help us elucidate the rational design of such a material system through characterization of the material properties of various molecular constructs.
Productive Uncertainty in a Laboratory Setting (PULSe): Engaging Students with Autism Spectrum Disorders (ASD) in Scientific Research
Peer mentors/research assistants are sought for the PULSe program. Those with ASD have particular modes of thinking and learning that is outside the realm of standard pedagogical practices. In the proper environment, these modes may help those with ASD to flourish. However, they are normally disadvantaged in basic learning environments. Academia is not wholly equipped to instill and help develop the necessary tools for ASD students to effectively function in society. Our aim is to bridge the learning gap.
Rheological Dynamics of Cellulose Nanocrystal Suspensions under Thermal Gradients
Our group has developed a rheological apparatus capable of sustaining spatial thermal gradients in shear rheometry. It is hypothesized that orthogonally superimposed thermal fields will produce linear, field-averaged rheological responses up to a threshold where anomalous, thermo-rheological dissipative phenomena will occur. The molecular influence of heat flow, especially at reduced dimensions, is from entropy production. Translational and orientational motions evolve as a molecular compensation mechanism.
Microfluidic Reactor Design for Helicene Synthesis
Helicenes are polycyclic aromatic compounds which are formed by ortho-fused aromatic rings that generate a non-planar, screw-shaped, three-dimensional structure that is inherently chiral and spring-like. The helical topology significantly contributes to the emergent properties of helicenes and has been garnering interest in the fields of nanotechnology, macromolecular and materials science.
Effect of nano-confinement on the thermodynamics of ionic liquids
Ionic liquids (ILs) are defined as salts that melt at or below 373 K. A typical IL is composed of a bulky organic cation and an inorganic or organic anion. As a group, many ILs tend to be miscible with many organic solvents. They show low vapor pressure, high viscosity and low degree of toxicity. At low temperatures ILs do not crystallize; instead, they form a glassy phase, while at high temperatures they flow with high viscosity, which is due to the strong electrostatic interactions between cations and anions.
Recycling, Regeneration, and Reusing Energy Materials
Manufacturing new energy systems such as fuel cells, batteries, wind turbines, photovoltaic cells, and catalytic reactors require materials that may be (1) precious, (2) rare on the earth, (3) not available or easily accessible in the United States, and/or (4) harmful for environment. Therefore, recycling (separation and reusing) energy materials is important.

Effect of Nanofiber layer patterned stripes on filter performance
Nanofibers have different wetting properties than glass fibers used in common filter media. Recent works with modifying surface properties of filter media shows non-wetting chemical coatings applied in striped patterns can improve performance of coalescing filters. The hypothesis for this work is the nanofibers which enhance wetting properties and droplet capture will similary improve filter performance if applied in striped patterns.

Tuning intermolecular distance to achieve tunable fluorescence
Controlling and measuring the intermolecular distance in supramolecular structures are important as well as challenaging. To achive both at the same time, we are chemically incorporating an aggregation-induced emission (AIE) luminophore into a charged macromoleculre, which can self-assemble into stable supramolecular structures of different intermolecular distances through the careful regulation of the physical interactions between the building blocks.
Photolytically degradable, hydrolytically degradable, and chemically recyclable commodity plastics
“White pollution” is a problem of massive scale. To replace the current nondegradable commodity plastics with degradable plastics, a key challenge is that the new raw materials must be readily available at costs comparable to current monomers such as ethylene and propylene. Low-carbon footprint is highly desirable for these raw materials in order to achieve overall environmental sustainability.
“Smart” degradable polymers: polymers with locked degradability that can be unlocked on demand
Synthetic degradable polymers are of pivotal importance for recycling and sustainability. While the degradability allows polymers to be recycled, it can also cause stability issue, which impairs the storage and functioning of materials.
