Materials Science & Engineering Research

Advances in materials result in advances in technology and in our daily lives. Materials science and engineering (MSE) research at Dartmouth supports discovery in fundamental applied engineering as well as translational science in areas such as ice physics, nano- and bio-materials, energy harvesting and storage, and materials modeling.

A diversity of concentrations is offered with collaborative synergies between the biological and chemical, biomedical, electrical and computer, energy, and mechanical, operations and systems engineering research areas. Graduate engineering students are expected to propose a plan of study that supports their interests, potentially including distinctive intellectual paths unconstrained by disciplinary boundaries and enriched by interdisciplinary synergies.

MSE research addresses key challenges in the following sub-areas supported by leading faculty in their fields.

Mechanical Behavior of Structural Materials

Increasing our fundamental understanding of structural materials leads to advances in manufacuring, construction, energy systems, medicine, and environmental science, to name just a few. Research focused on ice- and polar-related phenomena can not only facilitate planning for a more resilient future but also be applicable to metals, ceramics and other crystalline materials. Improving the durability of mechanical components and developing advanced composite materials—as well as better understanding the role of mechanical forces and shape engineering—can have significant economic ramifications throughout industry, particularly in the energy, manufacturing, medical and transportation sectors.

Properties of Functional Materials

Functional materials—classified on the basis of the functions they can perform—represent a fast growing set of advanced materials and composites, some properties of which (shape, electrical conductivity, mechanical properties, color etc.) are responsive to external stimuli. Because of their unique properties, these materials are advancing innovation in the areas of energy conversion and storage, sensing, electronics, photonics, and biomedicine.

Biomaterials

Advances in biomaterials facilitate biomedical research and inspire novel designs for implantable and bio-inspired devices. Research focused on orthopedic implants strives to optimize materials for weight, strength, formability, customization, and cost. Material-specific testing of implant retrievals is done to assess and understand changes that occur in vivo as part of the ultimate goal of improving patient outcomes. Work toward better synthetic tissue substitutes is also ongoing with the challenge of developing materials that mimic both the structure and mechanical performance of natural tissue and permit strong tissue-implant interfaces.

Energy Materials

Materials play a critical role in achieving a sustainable energy future. High-temperature materials enable power plants to increase their operating temperature which increases their efficiency. Demand for high-performance permanent magnets is growing for applications such as wind turbines and electric and hybrid cars. New materials for power electronics can help increase efficiency and reduce both size and cost and are also key for development of low-power sensors and energy harvesting for hybrid electronics. In the case of solar cells, it is highly desirable to use naturally abundant, environmentally-friendly materials which can also pave the way for novel cost-effective battery systems as well as sustainable lighting technology for the 21st century.
