Chemistry is truly the central science and underpins much of the efforts of scientists and engineers to improve life for humankind. TheMIT Department of Chemistryis taking a leading role in discovering new chemical synthesis, catalysis, creating sustainable energy, theoretical and experimental understanding of chemistry, improving the environment, detecting and curing disease, developing materials new properties, and nanoscience.
The Chemistry Education Office staff is responsible for administering the educational programs in the Department of Chemistry. Students can find answers to many questions about the undergraduate and graduate programs on the department website, and they are encouraged to stop by and see the staff in the office located in 6-205.
The student-run outreach programs in the Department of Chemistry aim to bring the excitement of chemical sciences to the community through lively demonstrations designed to illustrate a broad range of chemical principles. Graduate students visit science classes in high schools and middle schools in the Greater Boston area with a view to demystifying chemistry through hands-on experiments. ClubChem, an undergraduate chemistry organization, conducts Chemistry Magic Shows for elementary schools and youth programs in the Greater Boston area.
Chemistry is truly the central science and underpins much of the efforts of scientists and engineers to improve life for humankind. MIT Chemistry is taking a leading role in discovering new chemical synthesis, catalysis, creating sustainable energy, theoretical and experimental understanding of chemistry at its most fundamental level, unraveling the biochemical complexities of natural systems, improving the environment, detecting and curing disease, developing materials new properties, and nanoscience.
Our laboratory focuses on the science and applications of nanocrystals, especially semiconductor nanocrystal (aka quantum dots). Our research ranges from the very fundamental to applications in electro-optics and biology. There is an ongoing synthetic effort underlying all of this to address the challenges of making new compositions and morphologies of nanocrystals and nanocrystal heterostructures, and new ligands so that the nanocrystals can be incorporated into hybrid organic/inorganic devices, or biological systems. The fundamental spectroscopic focus is largely at the single dot level, were we are currently developing methods for probing the dynamical properties of the electronic structure of dots at time scales between 100 psec and 1 msec. We are also investigating the physics of multiexcitons in various quantum dots using both ensemble time resolved methods, as well as single quantum dot correlation spectroscopies. We are studying the charge transport properties of films of dots or dot/organic hybrids, within our group and with collaborators. These fundamental transport properties are critical for designing devices like electrically quantum dot based driven light emittiers, lasers, photodetectors and photovoltaics. We are studying these three classes of devices, also within our group and with collaborators. On the biology and biomedical side, we are collaborating with a number of biology and medical groups to design nanocrystal probes that meet specific challenges. These include nanocrystals that selectively bind to single receptors on cell surfaces for tracking applications, creating “smart” nanocrystals that sense analytes to report back on concentrations of species, including for example pH, which is important for following endocytotic pathways and tumor microenvironments, and systematic characterizations of the effect of size, morphology, charge, and other surface compositions, on the uptake (or clearance) of nanocrystals. This last information is critical for the design of nanocrystal probes as molecular imaging agents in vivo.
