Presentation requirement

Chem. 524, Spring 2013

(Modified from Syllabus) PRESENTATION: Each team of two students will present a "sales pitch", both presented orally with power point slides to the class and handed in as a written summary with an attached copy of the powerpoint presentation, to justify the purchase of a currently available commercial instrument to solve a research or analytical problem. They will detail its components and argue why those components are the best possible (including cost-benefit trade-off) choices for some particular experiment that will solve the problem chosen. Presentations will include results of comparison shopping to show why competing instruments are not as good for the particular application. This is the kind of presentation you will be required to make to your supervisors to gain funds for new instrumentation in the "real world".

NOTE: This is decidedly not a seminar or lecture or lesson. Your presentation must be designed to convince the listener about a specific targeted application, not educate in general. The goal is to convince your boss to get you the money to buy an instrument. It needs to be focused and to the point, argue your point about how to solve just the problem you have chosen, no peripheral pedagogy. The evaluation depends on the appropriateness of the solution to the problem, and its cost effectiveness. But it is not the best or fanciest instrument or even the cheapest solution that wins; it is the most appropriate one for solving the problem.

DO NOT try to teach a lesson about a certain kind of spectroscopy

propose to solve the problem -- this is selling not teaching.

Selection of a problem. Students in pairs must decide on a problem they wish to solve or attack with a spectroscopic tool. You should choose something of intrinsic interest to you since working on that will make the research easier and the presentation more compelling. For example this might be a topic you have read about that catches interest, e.g. pollution monitoring of Lake Michigan or improvements in energy efficiency of fuel or impurities in fast food or imported food. Alternatively something close to your research may be chosen, as long as it involves both optical spectra and analysis. Once a problem (global) is decided upon, a specific target analyte should become the focus of the project. This is critical and will make selection of a technique and discrimination between instruments easier. It may sound narrow, but it is a real world situation to analyze for one thing (or a few related things) at a time. Remember: This is a problem in analysis. Starting your talk or titling your presentation with: "To study . . ." is a recipe for failure!! On the contrary taking the approach: "To determine the concentration of. . . " and then tell me why I need to know that quantity, is a much stronger approach and will be strongly reflected by higher grades.

Select a Technique. Choosing a technique will depend on the analyte, time scale, sensitivity level needed etc. You need to think this through before settling on a problem and method. Any of the techniques that we cover in class will be appropriate--see later chapters of the book or the syllabus. However, your argument must establish that your technique will be the best choice within some working constraints--e.g. there might be better ways to analyze for a specific species but perhaps you might only need a certain level of sensitivity or accuracy due to some realistic conditions, you must justify it. For example, perhaps you want to monitor a process, so speed of sample throughput could be a more important issue than sensitivity or perhaps sensitivity is more important than selectivity, you must decide what is important and sell it to us, i.e.convince us. You may propose simple or complex approaches, the point is to defend your choice.

Select an instrument. Choose a vendor and specific instrument that can solve the problem at hand. The important issue is fit to the problem, not quality in some absolute sense. The choice could be cheap or expensive, it depends on the problem and what is needed to solve it--you must defend the choice. I can give you leads for vendors, and many are already linked on the various notes pages of our course Web Site, but Analytical Chemistry publishes instrumentation issue each year, as does Physics Today, Spectroscopy, and several other magazines. Previous students have found that Web sites of companies often offer the best detailed information, if available. If all else fails, direct contact via e-mail or telephone can get you answers. In the end you need the answers, must get them and communicate them to us.

Get competing vendors. You must have at least two alternate instruments (3 total, minimum, more are useful), preferably from other vendors that you show are not as good as your choice--for the problem you propose.

Make a summary of the strengths of your choice and the weaknesses of the competition. Charts or tables work well for this. Remember to include specifications. Price is an important variable--after all you are asking for part of your group or division budget to be spent on your idea, you must defend it! (However, getting approximate prices is fine, do not harass sales people.)

Prepare presentation, (aim for ~20 min., brief but directly on target will be rewarded) using an organized selection of PowerPoint slides that are useful for communication and for keeping you on track. These must succinctly convey your idea, your main points, not just lift items from web sites or present long tables. All members of the team must share in the oral presentation (divide up your time by topic/section/instrument, whatever works) and contribute to the written one. Use of Power Point to prepare professional looking slides is an important skill for a scientist, and you will eventually need to master this since it reflects approaches you will take in the outside world. (The Department has a projector if you need practice.) Keep it interesting and on target -- succinct justifications get a reward.

Write up a summary (4-6 pages) of your problem, the solution technique, justification for the best instrument and detailed comparison to its competition. Data from companies can copied from brochures or the Web and be submitted as an appendix (no need to retype them), but in addition a compact/tabular summary of the main points of comparison on these data sheets is required. Above all, a carefully written but succinct discussion is required for a top grade.

Due: hand in written summary plus a copy of your presentation at the next lecture after your presentation.

Timing: Presentations start in mid April, depending on volunteers. We may need extra sessions. E-mail (tak@uic.edu) me a list of partners and your topic by Feb.18, 2013, in the morning.

Bottom line: Focus on something specific and tell us how to solve it efficiently and economically for the situation you have chosen.
