Group Research

The goal of our research is to generate new knowledge that will deliver environmental protection, human sustainability, and fundamental insights via materials chemistry, physics, and engineering. We seek to educate researchers that will go on to become leaders in industry, academia, and government. We are experimentalists that use many different tools for our research, yet retain special expertise and interest in magnetic resonance (MR) spectroscopy and imaging. At the present time we are focusing our efforts in the follow areas: 

Metal Organic Frameworks

The Reimer group is part of the Department of Energy "Center for Gas Separations Relevant to Clean Energy Technologies," a center devoted to fundamental studies of materials tailored for gas separations. The Center focuses on solving these grand challenges in nanoporous frameworks such as MOFs:

1. discerning the distribution of local bonding environments, then use that knowledge for synthetic control of function

2. ascertaining what controls the creation of these elegant crystalline solids from molecules in solution

3. measuring how confinement direct transport of liquids, gases

4. development of new metrologies for interactions between walls and adsorbates to inform theory and simulation

5. de novo creation of a structured geometric and dynamic environment for a specific purpose

6. development of analytical methods that span multiple length and time scales

7. quantitate defects and their relation to synthesis condition and final properties and end use.

Artificial atoms and nuclear hyperpolarization

The intrinsic angular momentum of nuclei form the basis for such disparate fields as quantum information processing, spintronics, and analytical NMR spectroscopy and clinical MR Imaging. All of these fields are constrained by the limits place upon the population of energy states when nuclei are placed in an external magnetic field. Is it possible to transcend those limits and populate the energy levels of nuclear spins with something simpler than a huge laboratory magnet? We think so, and the answer is to use the known photophysics of artificial atoms in solids, then couple these “angular momentum engines” to nuclei.

In collaboration with Professor Carlos Meriles

at CCNY and Professor Alex Pines at Berkeley,

Professor Reimer’s group designs and

implements schemes to generate and control

nuclear spin information in diamond and other semiconductors. Our goal is to further the fundamental understanding of electron-nuclear interactions in semiconductors and deliver true control of the nuclear spin bath to those that seek to build quantum devices and high sensitivity NMR and MRI.

Applied Magnetic Resonance

The Reimer group has considerable expertise in developing and designing new magnetic resonance methods and equipment for materials chemistry. In operando catalysis, electrocatalysis, gas sorption are just a few of the examples of this work.  These studies involve multi-dimensional solid-state NMR, as well as pulsed-field gradient diffusion and multidimensional relaxometry measurements.
