Catalytic hydrogen transfer (4 projects)

We are preparing oxazolinylborate-coordinated group 9 compounds for catalytic hydrogen transfer. Our motivation for this work is that manipulation of hydrogen, as part of organic molecules, is extremely important for energy-related applications.  These application include oxidation state control for transformations of oxygen-rich biomass and oxidation/functionalization of petrochemicals.

Heterogeneous catalysis

To control heterogeneous catalysis at atomic and electronic-level represents one of the most challenge research areas. Using metal-organic frameworks (MOFs) as hosts of metal nanoclusters, we could reach an atomic and electronic-level control of heterogeneous catalysts. MOFs, as novel template materials for the synthesis of metal nanoclusters, have great potentials for catalysis due to their structural diversity, flexibility and tailorability, as well as high porosity.

Multifunctional Nanostructured Materials for Processing of Biomass

Students will work on a project aimed to prepare smart nanodevices for catalyzing sequences of chemical reactions to convert biomass into biorenewable fuels and chemical commodities. The nanostructured materials will be composed of organic and inorganic species that will work cooperatively to effectively promote chemical conversions behaving like nanosized assembly lines. The students will be trained in the synthesis and characterization of hybrid mesoporous materials.

Polymer-like Nanowires

Polymers owe much of their utility to their flexibility and morphology. For a long time it was thought that crystals could never replicate those properties because of their relative rigidity. We discovered a class of nanowires that challenges this belief and that shows polymer-like morphology and growth kinetic. It is the first example of a crystal that showcases the unique properties of polymer molecules.

Environments-by-design

Roots are essential to the growth and survival of a plant. They determine its resistance to stresses, droughts, and to soil erosion. Nonetheless, our ability to study them in their natural environment are limited by the complexity and opacity of soil. On the other hand, growing plants in transparent gels is a very poor mimic of the conditions that the plant finds in soil.

Materials-by-design

The properties of crystals are strongly dependent on their microstructure. For example, their strength, their conductivity, and their ability to capture sunlight depend strongly on the size and shape of the crystalline grains within them. Our control of microstructure (and our understanding of its influence on properties) is still far from optimal.

Neuroregenerative and Neurorepair Strategies

This highly interdisciplinary project seeks to develop approaches to facilitate repair and regeneration of the damaged nervous system. We will use a combination of biomaterials in the form of polymer conduits and/or scaffolds, adult stem cells seeded on the biomaterials, and use of physical, chemical, biological and/or electrical cues to orient cell growth, control stem cell differentiation and facilitate neuroregeneration using in vitro models.

Using Aptamers in Environmental Research

Aptamers are small nucleic acids that can be used in medical applications and as means of detecting specific molecules.  This is because these nucleic acids behave like antibodies and recognize specific molecules.  Aptamers can also function in the body either outside or inside cells.  We are developing the use of aptamers to increase the effectiveness of anticancer and other drugs for medical treatment and to image cells like stem cells.  We are also using aptamers to develop new monitoring methods for drugs of abuse and to monitor toxins in the environment.
