Research Focus
1) Basic Late Metal Complexes in Catalysis
Anionic heteroatom ligands on electron-rich late metal centers may serve both basic and nucleophilic functions, but are frequently too high in relative energy to be regenerated cleanly in catalytic systems. We are interested in exploring, from a mechanistic inorganic perspective, scenarios that might overcome that problem to enable new bond activation and formation reactivity. Specifically, we aim to use chelating nitrogen ligands to produce strongly basic catalysts that can heterolytically activate H-X substrates to yield nucleophilic M-X species. We explore this idea through the preparation and study of new transition metal complexes.
2) Microwave Heating in Organometallic Chemistry
Microwave heating has proved to be a powerful tool in the synthesis of ligands, and we are currently exploring the potential and origins of the apparent acceleration associated with the technique. This work includes both practical application of microwaves to the syntheses of ligands and their complexes, and investigation of the kinetic changes (or lack thereof) induced by microwave heating.
3) New Approaches to Inorganic Materials Synthesis
The synthesis of inorganic materials has historically been approached largely from an entirely empirical perspective, but rational synthesis using well-defined solution phase techniques and molecular precursors has shown promise as an approach to targeting specific surface structures, particle sizes, and other properties. We are currently exploring the preparation of novel molecular precursors for nanoparticles with photovoltaic applications.

Research Focus
In 1979 a method for breaking water into hydrogen and oxygen using sunlight was reported in the literature. The water-splitting scheme is shown below:
The above scheme shows the potential for generating water through electron transfer processes driven by sunlight. The process shown above does in fact generate hydrogen and oxygen using sunlight. However, the process is so slow that it is not useful. The limiting factor is the lifetime of the initially formed excited state termed the Metal to Ligand Charge Transfer state (MLCT). The shorter the lifetime of this state the less likely the process becomes. Hence, to successfully utilize this approach for solar energy conversion new compounds must be discovered that generate longer MLCT lifetimes.
The research in my laboratory focuses on the synthesis of new heterocyclic compounds containing the 1,10-phenanthrolin moiety for chelation with d-block metals with potential application as photosensitizers for solar energy conversion devices. The aim is to prepare the ligands, their metal complexes and to then measure the wavelength and lifetimes of their MLCT's. Once a variety of such compounds have been prepared and their MLCT's measured the long-term aim would be to begin to develop structure activity relationships where MLCT lifetimes would correlate with specific structural features.
The synthetic scheme currently in place in my laboratory utilizes the photocyclization reaction to construct the 1,10-phenanthroline moiety. The basic synthetic strategy is shown below:
Using this approach, we have synthesized the heterocyclic compounds shown below as well as
their metal complexes: Ru(bpy)2btp+2, Ru(bpy)2ntph+2 and Ru(bpy)2ntpl+2 where bpy refers to
bipyridine.
We are currently in the process of synthesizing these related structures through a modification
of the synthetic scheme shown above.
Finally, all the synthesized compounds will be used to prepare metal complexes for
measurement of their MLCT's.

Research Focus
My research program focuses on the effects of extreme conditions on microbes, proteins and nucleic acids. In particular, my lab studies the structural adaptations in proteins and the genome, that microbes need to have to survive under these conditions. My lab studies these adaptations through a combination of experimental and computational biochemistry and microbiology, structural biology, and bioinformatics.
Proteins and nucleic acids are very sensitive to their chemical and physical surroundings. Like the organisms from which they are isolated, these molecules tend to function and remain stable over a relatively narrow range of environmental conditions such as temperature, pH, salinity, and pressure.
What those narrow conditions are, however, can vary widely. Most organisms grow best at about 37 oC, under one atmosphere of pressure, with less than 0.1 M salt. But many extremophile microbes do not; some grow in hot springs where the temperatures range from 40 oC to ~100 oC, or in hypersaline environments, such as the Great Salt Lake, where the salinity is over saturation at +250 grams/L total salts. These organisms must have evolved adaptations to maintain the structural integrity of their proteins, nucleic acids, and membranes under these conditions, because non-extremophile proteins rapidly denature and/or lose activity when subjected to them. My lab focuses on adaptations for the extreme halophiles and related organisms, to determine how they survive and thrive in their extreme environment.

Research Areas: Medical isotopes and radiochemistry, high resolution vibrational spectroscopy and atmospheric chemistry, pedagogy of physical chemistry
Student experience required for research: CHEM 111, CHEM 112, enrolled in CHEM 232 for project 1, enrolled in CHEM 351 for projects 2 & 3, completion of CHEM 112 and programming or SME experience for project 4
Student experience gained from research: Ion exchange separations and radiochemistry for project 1, rotational and vibrational spectroscopy, quantum mechanics for projects 2 & 3, programming for project 4
Ideal preparation for: Graduate school in chemistry, employment in analytical labs, teaching chemistry
Research Focus
1) Ion exchange separations for the preparation of medical isotopes
Project 1 is part of a collaboration with the Idaho Accelerator Center to develop electron linear accelerator sources of medical isotopes. Medical imaging frequently uses technetium-99m which is produced by the decay of molybdenum-99:
99Mo → 99mTc + γ
Molybdenum-99 is currently produced by separation from a mixture of nuclear fission products. The reactors which are used for this process are aging which puts future supply in jeopardy. New methods of producing molybdenum-99 or alternative radionuclides are therefore needed.
The current focus of the product is the production of copper-67 via a photonuclear reaction in zinc:
68Zn + γ → 67Cu + 1p
This isotope decays by β emission with an average particle energy of 141 keV and also emits γ photons of energies 93 keV and 184 keV. These two characteristics make copper-67 suitable for simultaneous imaging and radioimmunotherapy which is a very desirable combination.
Our part of this project is the chemical separation of the copper-67 from the zinc target material. This is accomplished using an anion exchange resin under hydrochloric acid conditions where it is very selective for zinc and a chelating ion exchange resin under conditions where it is selective for copper.
The key criteria for a successful separation are specific activity, purity, and total yield. Specific activity is the ratio of the activity of the target isotope to the total mass of all isotopes of that element, usually in kCi/g. The purity refers to the absence of other elements, in this case primarily zinc. Total yield is the amount of the target isotope produced.
Future work will include developing other separations for radionuclei which are suitable for medical imaging, radioimmunotherapy, or both.
2) Rotationally resolved vibrational spectroscopy of atmospheric pollutants containing methyl rotors
Methyl nitrite is a gas phase molecule formed in the atmosphere by the reaction of methoxy radicals with nitric oxide:
CH3O• + NO• → CH3ONO (1)
In equation (1), the dots indicate that those molecules are radicals with unpaired electrons. This makes these radicals particularly reactive. In daylight, methyl nitrite rapidly photolyzes to reform these radicals:
CH3ONO + hν (λ≤440 nm) → CH3O• + NO• (2)
Since the methoxy radical (CH3O•) and nitric oxide (NO•) are both key intermediates in photochemical air pollution, methyl nitrite serves as a night-time reservoir, or storage molecule, that contributes to the "aged smog" phenomenon. This is where a pollution episode is worse on a second day due to pollutants that have not been removed from the atmosphere overnight.
High resolution Fourier Transform infrared spectrometry has been used on a variety of reactive molecules to measure their abundance in the atmosphere. This measurement technique uses the Beer-Lambert law which says that the absorbance is proportional to the concentration of the absorbing molecule and the path length over which this absorption occurs:
A(λ) = - Ln ( I(λ) / Io(λ) ) = (α(λ))x(concentration)x(pathlength) (3)
Here I(λ) and Io(λ) are light (as a function of wavelength) with and without absorber. The absorption coefficient is a characteristic of the particular molecule being studied. In the atmosphere, the concentrations are typically so low that a long pathlength (100's of meters) is typically required. The absorption coefficient is measured in a separate experiment, the pathlength is determined by the geometry of the experiment, and the absorbance is calculated from measurements of I(λ) and Io(λ) so that the concentration can then be determined. The role of laboratory studies such as in this project is to measure the absorption coefficient as a function of wavelength (λ), understand how it changes with pressure and temperature, and, most importantly, to understand why the absorption coefficient (or the "spectrum") of the molecule looks the way it does. This understanding is particularly crucial when the spectrum of the molecule being measured overlaps with the spectrum of other molecules that are present in the atmosphere and therefore might interfere with determining the concentration of methyl nitrite. Figuring out which lines (features in the spectrum) belong to which molecules can be a challenging task.
In a simple linear molecule like CO2, the spacing between the lines is directly proportional to the moment of inertia. Using the masses of the atoms and the moment of inertia, the bond lengths can be determined. For a large, asymmetric molecule like methyl nitrite, the pattern of lines is more complex and figuring out which lines correspond to which transitions between energy levels ("assigning the spectrum") is an involved process. The amount of information that can be obtained is also larger as well. The methyl group in methyl nitrite can rotate and this internal rotation can be investigated. Methyl nitrite also possesses two isomers. These two isomers only differ by rotation about the O-N bond. Both of these isomers are present in a sample of methyl nitrite and are observed in the spectrum.
The objective of this project is to measure and analyze the vibrational bands of methyl nitrite. The measurements will be made in the William R. Wiley Environmental Molecular Sciences Laboratory (EMSL) which is operated by Pacific Northwest National Lab (PNNL) for the Department of Energy. The High Resolution Infrared Spectroscopy Laboratory within EMSL has a Bruker IFS120 spectrometer that is capable of measuring infrared spectra at 0.0015 cm-1 resolution. Once the spectra have been measured at high resolution, they will be assigned and a nonlinear least squares fit will be performed to extract the constants characterizing the structure, cis-trans isomerism, and internal rotation of the molecule. Additional methyl rotor containing molecules to be investigated include methyl glyoxal, CH3COCHO.
3) Rotationally resolved vibrational spectroscopy of CFC replacement molecules
CFC's have been implicated in polar ozone depletion ("the ozone hole") as the source of chlorine atoms. Replacements for CFC's have focused on molecules which are inert enough to be used for the same purposes as CFC's but reactive enough to break down in the troposphere rather than reaching the stratosphere before breaking down like CFC's. Release of Cl in the decomposition of CFC's in the lower stratosphere results in catalytic destruction of ozone:
Cl + O3 → ClO + O2 (1)
ClO + O → Cl + O2 (2)
sum: O3 + O → 2 O2 (3)
This project will measure and analyze the rotationally resolved spectrum of replacement molecules such as HFC-125 (C2F5H) for reasons similar to those in project 2. CFC replacements could potentially be used in large amounts and are more stable than many pollutants and therefore reach concentrations in the atmosphere greater than that of a pollutant like methyl nitrite. An additional concern with these CFC replacements beyond pollutants like methyl nitrite is their absorption of IR radiation in the atmosphere. Changes in the absorption of IR radiation in the atmosphere (the greenhouse effect) can affect global climate.
4) Development of chemistry pedagogy materials using Mathematica
Project 4 focuses on the development of pedagogical materials for chemistry in general and physical chemistry in particular. The symbolic math engine Mathematica has a built-in command, "Manipulate[ ]", which makes it very straight-forward to turn a static visual into an interactive simulation. The Wolfram Demonstrations Project is a free online resource that publishes these "demos". For examples, see the following:
Lever Rule Applied To Phase Diagram For Partially Miscible Liquids
Rovibronic Infrared Spectrum Of A Rigid Diatomic Rotor
Future work on this project will involve design and production of more of these demos for physical chemistry and other areas of chemistry.

Research Focus
Elemental sulfur (S8) is produced in abundance during petroleum refinement, generating millions of tons of waste. The Jenkins group uses a technique called inverse vulcanization to make new polymeric materials from elemental sulfur. Sulfur becomes the backbone and acts as the solvent in this reaction eliminating the need for volatile organic solvents. Natural monomers including those from garlic have been incorporated into these materials further promoting aspects of green chemistry.
In the lab, students examine fundamental aspects of polymer synthesis and characterization. These polysulfides contain dynamic bonds, which offers an opportunity to create modifiable polymer frameworks. These materials have applications in heavy metal remediation and adhesives among others. The ultimate goal in the lab is to utilize petroleum waste products for the development of functional materials.
Students will learn polymer synthesis and a variety of instrumentation techniques including NMR, ATR-IR, UV-Vis spectroscopy, gel permeation chromatography (GPC), and differential scanning calorimetry (DSC) as well as common chemistry software. Additionally, regular group meetings will provide both written and verbal communication skills.

Research Focus
Our analytical chemistry research focus is in an area termed chemometrics concerned with “how to obtain chemically relevant information out of measured chemical data, how to represent and display this information, and how to get such information into data.”1 While this area of research was well established in the early 1970’s, the area is now popularized as data science, machine learning (ML), and artificial intelligence (AI).
We concentrate on developing computer algorithms to determine mathematical relationships between chemical data and analyte properties desired such as the concentration estimate of a substance in a sample. Algorithms are trained to recognize data patterns and predict properties for new situations. For example, training an algorithm to distinguish noninvasively measured spectra of cancer cells from non-cancer cells. Our mission is creating new algorithms to solve difficult analytical chemistry problems by leveraging sample and measurement matrix effects (hidden physicochemical properties) as information to work with. Our current emphasis is using the immersive analytics tool virtual reality (VR) allowing the human to see, touch, and hear the data in order to improve on data decisions compared to autonomous algorithms including our own. Some research projects follow.
Multivariate Calibration (Modeling): Central to many disciplines is multivariate calibration including food analysis, food adulteration detection and authentication of product origin, environmental monitoring, industrial process control, medical diagnosis
such as disease detection, pharmaceutical analysis, forensic analysis, detection of hidden radioactive material, and the list goes on. Work in our laboratory consists of developing new mathematical processes and the corresponding computer algorithm implementations in order to improve calibration quality in conjunction with eliminating user decisions making calibration and subsequent analyte predictions automatic. A persistent multidisciplinary problem is developing a calibration model in one set of environmental, instrumental, physicochemical conditions (the primary source conditions) to now work in new target conditions, i.e., the calibration maintenance (transfer) problem. In ML language, calibration is called training and unknown samples to be predicted are named the target samples.
Our laboratory developed two approaches to solve this problem that now allow on-site analyses with handheld devices including consumer applications. One solution is local modeling.
With the ever-growing availability of spectral data, e.g., near infrared (NIR), Raman, fluorescence, and other spectral processes, there is a high need for computer algorithms to mine through such data libraries and identify those spectra similar to a spectrum just measured for a new target sample. The user is interested in using the new spectrum for quantitative analysis of an analyte, perhaps glucose content for diabetic, and a model must first be formed using calibration spectra matrix matched to the new target sample spectrum. Because the analyte amount in the new sample is not known, identifying fully matched calibration samples from a library is not a simple task. However, we have developed an algorithm to accomplish this objective that we call local adaptive fusion regression (LAFR). Key takeaways for LAFR are: (1) models are formed by an understandable process based on physicochemical properties and principles with a linear Beer’s law-like relationship, (2) final calibration sets bracket target sample analyte values, and (3) all adjustable parameters are self-optimized. Ongoing work involves providing a reliability measure based on the probability of a correct prediction as well as using VR to further refine the LAFR calibration set to those samples best matched to the target sample.
The second approach is model updating by the transfer learning approach domain adaptation. In collaboration with Erik Andries at Central New Mexico Community College, we now have a null augmented regression (NAR) algorithm that correctly predicts new target samples. Models are formed using the new unlabeled target samples for which is prediction is desired.
We have just developed NAR constant analyte (NARCA) as a ne local modeling approach where the multiple spectra are measured from a single sample and eventually transformed to the analyte amount present in the target sample. The sample can be homogeneous or slightly heterogeneous.
VR and Vision Impaired: As noted above, we have various ongoing VR projects. The goal is to develop hybrid systems relying on the computer for the intense chemometric calculations and VR for the final data analysis decisions. By using VR, samples have spatial relationships as with any flat screen graphic but with PRISM rendered in VR, we are able to provide a shape to each sample data point. Shapes are relative to the sample-wise matrix effects determined by PRISM.
Ultimately, we are going to use our VR data analysis for the vision impaired where the user will be able to hear where data clouds are and then using haptic gloves feel the difference between the samples for deciding if a sample is an outlier, or a class member, or which calibration samples are matrix matched to the target sample for local modeling.

Research in the Nickerson lab is focused on adapting traditional organic transformations that use metal-halide based Lewis acids to more sustainable processes using Lewis acidic heterogeneous materials such as clays and zeolites. This adjustment makes methods safer and more sustainable because the heterogeneous materials are easily recycled and reused and the waste production is far less than when using traditional Lewis acids. Current projects are focused on modifying the Friedel-Crafts acylation and the Prins-pinacol rearrangement.
The proposed research will provide student researchers valuable skills in organic synthesis, method development and materials chemistry.

Research Focus
1) Plasma Enhanced Chemical Vapor Deposition of Thin Films of Semiconductors
We are developing PECVD methodology to deposit amorphous chalcogenide materials, like GexSy, GexSey, as possible phase memory or ion-conductive memory materials. Germanium sulfide is also known to have a large difference in conductivity between it amorphous phase and its crystalline phase. This is essential for phase memory devices. It is also known to have a high ionic conductivity toward Ag and lithium ions. This property is essential for ion conductive or bridge-conductive memory (also known as resistive RAM) and in Li battery applications. GexSey is likely to have higher ion conductivity and we are investigating the ion-conductivity as a function of the relative ratio of the Ge to Se in the PECVD films. We are also doping more metallic elements like Sn into the films and are studying how this affects the conductivity. This work is being performed in conjunction with Prof. Kris Campbell at Boise State University.
It is apparent at this point in time that we have reached a junction in the path we will take to power the world of the future. If we intend to have sufficient non polluting energy for the growing and maturing world it is apparent that solar energy conversion will likely represent a large component of the total energy sources available for humankind. Thin films of germanium and tin sulfides and selenides also have potential application in this area.
2) Investigation of Intermolecular Interactions in Ionic Liquids by Density Functional Theory Computations, Physical Measurements, and Spectroscopic Investigation
Ionic Liquids are ionic compounds that are liquids at room temperature. Many of these liquids consist of cation with long organic groups and a central positively charged atom, and an anion like dicyanamide or bistriflimide. We are working with Dr. Donna Baek’s group at the INL performing fundamental studies of several of these liquids, which potentially could be used as electrochemical media for rare-earth metal recovery. The viscosity and conductivity of these ionic liquids are important factors that must be considered. We are making conductivity and viscosity measurements on these liquids, at several temperatures, to help gauge strength of the intermolecular interactions present in these liquids. Additionally, 2d NMR studies we are performing suggest that ordering on a nano-sized scale may exist in these liquids. We are also using the computational chemistry program Gaussian 16, to perform Density Functional Theory calculations of the interaction energies to correlate with the physical and spectroscopic measurements. These are being performed via the HPC (High Performance Computing) center at the Idaho National Lab.
3)Thermal Imaging for Serial Number Recovery
We are working on a way to recover defaced serial numbers with a nondestructive method. Currently serial numbers on products like firearms or automobile parts which have been partially or completely filed off are recovered using a wet chemical method. The wet chemical method often recovers the serial numbers piecemeal while etching away the remnant memory of the number that exists in the plastic deformation zone. The plastic deformation zone is an area where the properties of the material have been altered due to the large force needed to imprint the numbers in the material. With the wet chemical method, one may get only one chance at recovering the number, since the remnant of the number is often destroyed as the metal is etched away, and so other non-destructive methods are sought that leave the evidence in a state that is available for further testing or verification at a later time.
We plan to make use of the difference in heat flow in the plastic deformation zone to recover the serial numbers. This will be accomplished through the use of real-time infrared thermography and image processing techniques. Since this technique does not etch away more of the material, it is nondestructive and leaves the sample available for further testing at a later time.

Research Focus
1) Archaeological evaluation of prehistoric stone-tools:
Understanding the specific use and purpose of archaeological specimens such as stone axes and grinding stones continues to be a perplexing problem. Traditional form-function relationships provide strong clues to the specific use of these implements. Yet, chemical analysis of residues preserved on these tools may provide key information in identifying how the tool was implemented. Our research goal is to provide chemical analysis capable of identify trace components associated with plant and animal materials. Since different plants and animals produce different types and quantities of organic compounds we can associate these to the toolUs actual use.
2) Geo-thermometry in the Yellowstone Basin:
Underlying the beauty of the Yellowstone plateau and its unique geothermal features is a somewhat restless volcanic caldera. There is much interest in monitoring the activity of this underlying heat source. One measurement of the magma activity is obtained by water chemistry of the geothermal springs located in the greater Yellowstone ecosystem. While it is difficult or impossible to monitor the many individual features, our research proposes a survey measurement be obtained by monitoring chemical indicators from hot springs as they exit the drainage basin in the surface water of three rivers. Research studies include both field and laboratory studies.
3) Solar Remediation of Environmental Contaminants:
A) Photo-Oxidation of inorganic cyanides by solar irradiation.
Cyanide is used in the mining of precious metals, especially gold extraction. The use of solar irradiation is being investigated as a source of decomposition and eventual oxidization of cyanide compounds. The use of semi-conductor oxides as photosensitizers has increased the quantum efficiencies of these processes.
B) Photo-Chemical remediation of TCE using ceramic micro spheres.
Industrialization has lead to the wide use and abuse of toxic organic solvents. The use of TiO2 as a photo-oxidation catalyst for these compounds is well recognized. In an effort to remediate contaminated surface waters in situ, photo-sensitizers are being placed on ceramic micro sphere. These hollow micro spheres allow catalysts to be easily delivered and retrieved from natural waters. The feasibility and effectiveness of using these remediation technologies are being evaluated.
