Renovation Inspires Technology Innovation in Undergrad Organic Lab

March 16th, 2012 in Alumni, Front Page, PFF, Schaus, Scott, Snyder, John, Students, Teaching, Undergraduate

Undergraduate Organic Lab

BU Chemistry has dramatically improved the undergraduate organic chemistry laboratory by giving students access to major research instrumentation and state-of-the-art technology. By enabling more modern experimentation, these resources foster critical thinking and problem solving skills that prepare undergraduates for  graduate and pre-professional schools or for careers in industry. Advanced experimentation also enables more sophisticated student-designed research-type projects.

Renovations and instrumentation

Renovations in the Metcalf Center for Science and Engineering (Summer 2011) have transformed our organic chemistry instructional laboratories into an 6,350 sq. ft. suite with fume hoods and bench areas for each student, auxiliary support space, and a chemical stockroom. Space has been dedicated for an undergraduate instrumentation center for with fully automated high field nuclear magnetic resonance (NMR), ultra-performance liquid chromatography–mass spectrometry (UPLC-MS), Fourier transform infrared spectroscopy (FT-IR), and gas chromatography-mass spectrometry (GC-MS). Microwave reactors allow for rapid reaction rates, enabling multistep syntheses to be undertaken in a single day.

Advanced Technology in the Laboratory Curriculum

The entire laboratory curriculum of our sophomore-level organic chemistry sequence has been transformed with the adoption of the “paperless laboratory” through the use of electronic laboratory notebooks. Spearheaded by Professor John Snyder and Professor Scott Schaus and Postdoctoral Faculty Fellow, Seann Mulcahy, integration of these technology resources have enabled the creation of an open-access repository of laboratory protocols, design of laboratory experiments that facilitate sharing of data between students and between disciplines, exposure to automated NMR, GC-MS, and UPLC-MS, and remote download and manipulation of spectroscopic data.

  • Undergraduate Organic LabFast Forward to the 21st Century -The new instrumentation advances undergraduate capabilities well beyond those in traditional sophomore organic textbooks that repeat traditional experiments. Instead, we have designed novel, research-oriented, exploratory experiments that have applicability to modern organic chemistry. These include cross-coupling experiments, olefin metathesis, and many others. Experiment protocols are available on BU’s Digital Common site (DCommon), an open-access online repository that is accessible not only by our students, but by outside instructors as well. Users can be granted upload privileges to deposit modified or new protocols thereby creating a rich resource to the worldwide research community. In addition, a DCommon collection of NMR and UPLC-MS spectra is being compiled as a teaching tool for organic chemistry courses.

Undergraduate Organic Lab

  • Major Instrumentation – BU is unique in using the latest instrumentation for routine, hands-on training at the sophomore level. The laboratory’s state-of-the-art instrumentation also allows comprehensive characterization of synthetic material prepared in each experiment. Students now routinely run 1H and 13C NMR (and 2D COSY), UPLC/MS, GC/MS, and FT-IR on their own samples and to obtain a set of data which approaches the quality needed for publication.

 

Undergraduate Organic Lab

  • Into the Cloud – Our students are now using fully electronic laboratory notebooks, which they populate  on their laptops with reaction details, procedural notes, and safety protocols. Analytic data and spectra (manipulated and interpreted remotely) are uploaded into the notebook and serve as part of their final laboratory reports.

Teaching Lab Protocols Now Freely Shared

Prof. John Snyder

Boston University Chemistry has launched a new Digital Common site for organic chemistry teaching lab protocols.  According to Prof. John Snyder, “developing a freely accessible, dynamic data base of sophomore organic lab experiments was driven by the reality that we were creating most of our sophomore course labs rather than relying on  a lab textbook. In fact, many colleges and universities are doing the same.   As PFFs from our department have gone on to faculty positions, the potential for having a large number of talented contributors to the database became rather obvious.” Early users / contributors include PFF alumna Prof.  Amy Bradley (Wilkes University) and Prof. Lauren Rossi (Roger Williams University).  Instrumental in developing the free access database is current PFF, Dr. Seann Mulcahy.

The BU Digital Common is an open access repository, which means that the full text of the work deposited here is freely accessible to the world via the web. BU Chemistry organic lab instructors have placed protocols developed over the years to be freely and easily accessible to other instructors. Users can download and modify these protocols to use in their own courses as they see fit. Users may also be granted upload privileges to deposit modified or new protocols that will be of use to the world-wide teaching community.

Dr. Rosemary White demonstrating the ideal gas law at Chemistry Day 2010

On April 30, high school students from Boston Community Leadership Academy (BCLA) visited the BU Chemistry Department for our second annual Chemistry Day. The forty-five BCLA students learned about acids and bases, gas laws, and chemical reactions at a jaw-dropping demonstration show. They also explored rates of reactions and electrochemistry in two hands-on laboratories run by BU graduate student, Daniele Ramella, and Postdoctoral Faculty Fellow, Rosemary White. Then the students toured chemistry research labs where graduate students and postdocs taught them about their current research. The event concluded with a picnic lunch, sponsored by Cynthia Brossman of LERNET. Chemistry Day was organized by Anais Gervais (BUWIC), Riya Luhar (Chemia), Rosemary White, and Susan DeSensi. The BCLA students are in Arielle Saavedra’s 10th-grade chemistry class. Throughout the semester, BU undergrads Jennifer Kole, Ariana Sherman, and Mike Zimmerman visited Arielle’s classes as part of the Chemistry Outreach Program. The Chemistry Outreach Program, organized by Dr. Susan DeSensi and Dr. Rosemary White, both of the BU Chemistry Department, sends BU undergrads to BCLA, English High School, and Fenway High School to work with the chemistry classes, perform demos and labs, and share their excitement for chemistry. Please check out some Photos from this wonderful event.

Snyder Recognized for Excellence in Student Advising

Professor John Synder

For the second year in a row, a member of the Chemistry faculty  has received the Templeton Prize for Excellence in Student Advising, the top undergraduate advising award given by the College of Arts and Sciences.

The 2009 recipient is Prof. John Snyder. Despite his busy schedule which involves teaching, research, and management of two NSF summer undergraduate research programs, this dedicated advisor and mentor is always available to meet with undergraduates. One student related that “Anytime I have a problem, personal or academic, Dr. Snyder was right there and took the time to give me advice and help. He even went out of his way to find me a scholarship for the summer so I could take two classes that I wouldn’t have been able to afford otherwise.”

Among many enthusiastic accolades, another student stated: “Being a freshman and ignorant of many aspects of college life, I had trouble adjusting. It was always my dream to enter graduate school one day. However, I really had no clue what to do to get there. I sought the advice of my professors, but Dr. Snyder really helped me the most. He would spend time to get to know me, understand what type of person I am, help me to learn where my strengths and abilities are, and to help me to discover which aspect of chemistry I was most passionate about. In doing so, I personally felt that Professor Snyder went the extra mile to be a part of my academic journey. It is professors like Dr. Snyder that make Boston University such a great school.”
