Areas of Research
Our faculty members are highly dedicated, experienced teachers and researchers. Many have established interdisciplinary collaborations with colleagues in other units on campus, such as the Frontier Institute for Research in Sensor Technologies (FIRST), the Forest Bioproducts Research Institute (FBRI), the Institute for Molecular Biophysics, the Maine Center for Research in STEM Education and the Sustainability Solutions Initiative. Teams of UMaine faculty, postdocs, graduate and undergraduate students are researching biomass conversion and sensors for detection of environmental pollutants; teaching with analogies in the chemistry lab; studying new methods to identify biomarkers for cancer, miniature devices for applications from genomics and cell biology to catalyst screening for biofuel production. Specific areas of research and the associated faculty are listed below.
Analytical Chemistry
Analytical chemists examine substances to determine their composition. They also look at how elements in a compound interact with one another. Their skills are also used in the field of environmental chemistry to detect chemical pollutants in the environment.

Inorganic Chemistry
Inorganic chemistry encompasses the entire periodic table with research from catalysis to alternative energy and from medicines to materials. Since inorganics are key today to environmental, energy, and nanomaterial research and the chemical industry, inorganic chemists find themselves at the forefront of research to identify the relationship between electronic structure and function: the fundamental issue of understanding properties at the molecular level.

Organic Chemistry
Organic chemists investigate the structure, properties, and reactions of compounds that contain carbon. Organic compounds are all around us; they are in our DNA, peptides and proteins and they are central to the economic growth of the U.S., in industries such as plastics, fuel, pharmaceutical, coatings, and agrichemicals. Organic chemists are also skilled at selectively modifying molecules to enhance a desired activity and specificity of action, while decreasing undesired side effects.

Physical Chemistry
Physical chemists aim to understand at the sub-atomic, atomic and molecular scale the structure and behavior of materials and the way chemical reactions occur. Computational physical chemists apply math and physics to develop theories and models that unravel mysteries from protein folding to nanoparticle properties. Experimental physical chemists use computers and large instruments, including lasers, mass spectrometers, and microscopes to measure structure and dynamics of chemical processes. Such knowledge is relevant to nearly every area of chemistry, from biological to nano-technology to environmental.

Alternative Energy
Energy consumption is a major global challenge to achieving a sustainable planet. Developing alternative sources of safer, cleaner, renewable energy is a goal of green chemistry. Solar, wind, and biofuels each play a role in providing alternative energy. Chemists are contributing to development of new technologies through improved batteries, new materials for photovoltaics, better fuel cells, and production of energy dense liquid fuels.

Environmental Chemistry
Chemists working in the field of environmental chemistry study the sources, effects, and reactions of chemical species in the air, water or soils. Environmental chemistry relies heavily on the use of quantitative methods for following the fate of chemicals in the environment. Environmental chemists draw on a range of concepts from chemistry and various environmental sciences to assist in their study of what is happening to a chemical species in the environment. Important general concepts from chemistry include understanding chemical reactions and equations, solutions, units, sampling, and analytical techniques.

Nanoscience and Materials
When materials are synthesized on the length scale of nanometers, their properties often behave dramatically different from bulk materials. Research in this area focuses on the relationship between the microstructure and the macroscopic properties of materials used in applications from plastics and coatings, to ceramics and catalysis, to biocompatible materials for prosthetics. The field is very multidisplinary, and uses highly specialized instrumentation for imaging and manipulating matter at the nanoscale.

Photochemistry
Photochemistry is the study of chemical processes that occur due to the absorption of light. Researchers explore interactions with light to cause chemical reactions, to understand the spectroscopic properties of molecules, and to quantify compounds.
 |
Surface Chemistry
Surface chemistry is the study of chemistry that occurs at surfaces, interfaces, and thin film materials. Researchers create new materials and study the interaction and reaction of molecules with surfaces for applications from catalysts to sensors.
|
 |
Synthesis
Research in synthesis aims to generate new methodologies to create new molecules, control molecular transformations, and understand fundamental mechanisms in chemical reactions.

Theoretical and Computational Chemistry
Theoretical chemistry is a branch of chemistry, which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry; for example, the concept of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular orbitals, orbital interactions, molecule activation, etc. Computational Chemistry is a branch of chemistry that uses computer simulation to assist in solving chemical problems. It uses methods of theoretical chemistry, incorporated into efficient computer programs, to calculate the structures and properties of molecules and solids.

Wood Chemistry
Wood chemistry is a broad, interdisciplinary field focusing on the chemical and biochemical aspects of trees and products such as pulp and paper that are derived from trees. Extensive use of analytical instrumentation is required to determine the chemical composition of forest products and processes. The wood chemistry program is the only such program in a chemistry department in the United States. We are developing methods to separate the major components of wood so that it can be used more efficiently for high value products and energy production.

Sustainable and Green Chemistry
Sustainable and green chemistry explores the use of non-petroleum feedstocks to create chemicals and looks to implement the principles of green chemistry in synthesis. Researchers are exploring new synthesis pathways, new catalysis, new materials, and understanding the complex nature of natural sources of molecules and materials.
 |
Polymer Chemistry
Polymer chemistry is the study of the synthesis of new polymeric materials and how molecular structure affects their macroscopic properties for applications from packaging to biomedical materials. Researchers explore new chemistries for polymerization, new sustainable polymers, and how to control polymer molecular architecture.

Chemical Education
Chemical education focuses on understanding how students learn chemistry, how best to teach chemistry and how to improve learning outcomes by changing teaching methods. There is a constant need to update the skills of chemistry teachers so chemical education is also concerned with the appropriate training of chemistry instructors. Chemical education research utilizes both quantitative and qualitative data collection methods.

Biological Chemistry
Biological chemistry is a highly interdisciplinary field linking biology with bioanalytical, bioorganic, bioinorganic, and biophysical chemistry. Chemists working in this area apply chemical techniques and tools to understand the molecular and cellular basis of biological processes. Research in this area includes the design, synthesis and analysis of structure and reactivity of molecules in biological contexts.

Catalysis
Catalysis is the study of mechanistic details of chemical reactions. Researchers use homogeneous and hererogeneous catalysts to control the transformation and creation of molecules as well as understanding the mechanism of activation.
