46th Midwest
39th Great Lakes
Joint Regional ACS Meeting
Technical Program

What’s an ACS meeting for? Foremost, it has to be the technical program, around which all the other features and attractions are built. We are fortunate this year to be able to call on members and institutions from both the Midwest and the Great Lakes Regions to organize symposia and contribute oral and poster presentations.

If you can’t find enough interesting and pertinent content in the special symposia, don’t forget that there will also be general oral sessions and poster sessions with more to pique your scientific interest.

Instructions to presenters

Some helpful hints to oral and poster presenters can be found at the bottom of this page.

Full program now available

The complete final program of technical presentations, oral and poster, is now available. Check carefully for the many different formats available:

  1. to build your itinerary for the meeting (ACS login required), use the online searchable database with itinerary builder
  2. if you don’t have an ACS login or don’t need the Itinerary Builder, use the online searchable database without itinerary builder
  3. overview of the symposium sessions and special events as a one-page grid (pdf, 87 kB). The special events are not included in any of the other program formats, so don’t miss this.
  4. schedule of talks and posters, titles/authors/times/locations for each session (58-page pdf, 260 kB). In rare cases, there will be discrepancies between this document and online versions of the schedule due to last-minute requests for changes; in such cases, this document is definitive.
  5. compilation of all full-text abstracts, but no schedule (384-page pdf, 5.8 MB)
  6. the author index, just author name and abstract number (16-page pdf, 280 kB)
  7. complete program booklet (132-page pdf, 5 MB), includes #3, 5, and 6 above, plus sponsor acknowledgments, welcome letters, special event participant bios, award citations, exhibitors with brief company descriptions, Expo floorplan, Local Sections within the Midwest and Great Lakes regions, venue map, and Westport Plaza map.

ACS Leadership Development courses

The ACS Leadership Development staff will offer two courses during MWRM/GLRM 2011. These courses offer leadership training appropriate for use in ACS governance, but teach skills that are also widely applicable in the workplace. The courses are offered at greatly reduced prices to ACS members and non-members, but enrollment is limited so sign up early. Fees for each class are $15 for ACS members, $30 for non-members, and $5 for unemployed ACS members, students, and teachers.

  • Collaborating Across Boundaries, Friday, October 21st, 8 am–12 noon, in the Skylight Room, facilitated by Jason Ritchie
    Leaders in many roles (especially at more senior levels) need to be able to work effectively with leaders and members in other roles and units to accomplish their objectives. This course provides leaders with strategies and tools to make collaboration more productive, including developing common goals, ensuring equity between what parties bring and what they gain from the effort, gaining members’ commitment, and establishing trust and resolving conflict.
  • Communication Strategies, Friday, October 21st, 1–5 pm, in the Skylight Room, facilitated by Frankie Wood-Black
    As a senior leader, you will encounter an increasing number of opportunities to represent your organization to outside parties, stakeholders, and media, often under pressure and in highly visible situations. This level of communication requires a higher understanding of communications to ensure the best representation possible. This interactive course introduces you to executive-level communications; you will learn how to skillfully communicate new insights, keep others informed, report on new endeavors, and communicate in an interesting and compelling manner.

To register, please log into the ACS Center for Professional Development, www.acs.org/professionaldevelopment. For additional information, contact Alexa Serfis, barnoski@slu.edu

PLTL Workshop

Saturday, October 22nd, 9–11 am in the Alpine II Room
If you haven’t already implemented Peer-Led Team Learning in your curriculum, it could be the next big thing for you. Dr Gina Frey will guide workshop attendees through the process of successfully implementing PLTL and will present data from the program in General Chemistry at Washington University.

Eat, socialize, network...and more...

Instructions to presenters

Giving a talk or presenting a poster at the meeting? Here’s what you can expect and how you can best prepare.

Oral presentation

We will provide a computer, an LCD projector and a screen for your presentation. A PowerPoint file (saved as a .ppt file, not pptx) is the preferred format.

Plan to arrive at least 20 minutes prior to the start of your session to meet your session chair. Be sure to inform your session chair of any important title or name pronunciations.

For easier transitions between talks, we ask that you upload your presentation onto the session chair’s computer. Submit your presentation to your session chair at least 20 minutes prior to the start of your session. It is preferred that presenters bring their presentation on a flash drive (memory stick), as compatibility problems may occur with CDs. You may want to bring a backup or second stick with the talk in case there are problems with the first one. If you are using a different format than PowerPoint or PDF, you should bring your own laptop computer (and any adapter cable you may need to connect to the projector).

Pay attention to the time that you have been allotted for your presentation. Be sure to leave at least 3 minutes for questions/discussion. Due to a tight schedule, we can not allow presentations to run over their allotted time. You are encouraged to continue discussions at coffee breaks, lunch, or outside the session room.

Poster presentations

The poster boards can hold posters that are a maximum size of 72 inches wide × 48 inches high (1.83 m wide × 1.22 m high).

Please arrive 20 minutes prior to the start of the poster session to mount your poster on the display boards. Check in with staff to find the exact location for your poster. Push pins will be provided.

It is an excellent idea to practice a 2–3-minute overview of your poster to present to interested attendees. You may also want to have reprints or business cards available to hand out.

Poster sessions are 1½ hours long (2 hours for the SciMix poster session). Presenters should be available in the poster/exhibit venue throughout their poster session.

Posters will need to be removed from the display boards promptly—within 10 minutes of the conclusion of the session—to accommodate the presenters in the next session.

If you need more information or have problems with this site, please contact the WebMaster.
