Maclachlan named 2018 Outreach Volunteer of the Year by the Northeastern Section of the American Chemical Society

In an effort to recognize the immeasurable outreach efforts made by local section volunteers, the American Chemical Society's Committee of Community Activities (CCA) has established the Local Section Outreach Volunteer of the Year award program. Each local section has an opportunity to recognize one individual annually for demonstrating extraordinary outreach volunteer service within the section. Volunteers are only eligible to be recognized once every five years.

In recognition of their exemplary outreach efforts, ACS provides each participating local section with a certificate and gift to present to the awardee during a local section meeting or another event. The program and some awardees will also be recognized in an issue of Chemical & Engineering News (C&EN) later this year.
Jennifer Maclachlan is the 2018 Northeastern Local Section ACS (NESACS) Volunteer of the Year. Maclachlan has been involved in numerous public relations and outreach activities in 2017, which includes Chair of the ACS Committee of Public Relations (2016-2018); member of the NESACS Public Relations Committee (2010-present); Public Relations Chair for the Small Chemical Business Division (2010-present); co-founder of the Cape Cod Science Cafes in 2011 during the International Year of Chemistry, the most recent Cape Cod Science Café event included a “Science in Your Swimsuit” Café (50 children) in 2017 and again, in 2018, and the annual Wicked Cool STEM Science Café with the Cape & Islands Council of the Boy Scouts of America (600+ attendees-Jennifer been coordinating NESACS participation at this event since 2013); organizer of the NESACS outreach tables at the AAAS Family Science Days at the Hynes Convention Center (2013 and 2017); and co-founder and co-organizer of the STEM Journey Event on Cape Cod (800+ attendees annually) since 2014.

An Improved Method for the Analysis of ppt Levels of Mercury in Ambient Air

Assignment Status:AssignedSession Title:ACS (American Chemical Society) Poster Session
Session Date03/17/2019Starting Time:( Slot # 25 )
SUNDAY POSTERS: 3:30pm-7:30pm Author(s) present 5:30pm-7:30pm Location: Pub Pittcon, Pennsylvania Convention Center, Philadelphia, PA

Authors: Driscoll and Maclachlan
A method for the analysis of ppb levels of mercury using a photoionization detector (PID) with a 10.6 eV lamp was described several years ago. The ionization potential for Hg is 10.43 eV, so it responds to the PID. A new gold film in the preconcentrator was used to collect and concentrate the Hg vapor from the air.

The system is purged at 200 degrees C to remove any water vapor and/ or VOC’s from the gold film. This also improves the selectivity of the PID since all VOC’s which would respond are removed. Then the gold film is rapidly heated to 550 degrees C to remove the Hg.
We have decreased the volume of the preconcentrator by more than an order of magnitude and changed the heating method. Instead of a cartridge heater we are using an RF heater. We are now able to heat the low mass concentrator at ten times the speed. This gives us a much sharper peak and a much faster cool down time. We have improved the detection limit for Hg from about 10 ppb to < 1 ppb and with a reasonable sampling time, we can achieve < 1 ng/m3 which is a typical number for ambient air.

Fast GC PID & FUV Detectors for Measurement of Greenhouse Gases in Livestock Barns

Assignment Status:AssignedSession Title:Analytical Agricultural Applications (Half Session)
Session Date03/17/2019Starting Time:03:05 PM ( Slot # 1 ) 

Authors: Driscoll and Maclachlan
Carbon dioxide, methane, and nitrous oxide are important greenhouse gases. In fact, methane is the second largest anthropogenic greenhouse gas (GHG), that contributes 14% of total anthropogenic GHG emissions estimated in 2004. Agricultural emissions of methane account for about 60% of the total methane from anthropogenic sources, of which 25% arises from fermentation in livestock. A considerable effort is underway to modify the diets of livestock to reduce methane emissions. A rapid analysis of these components is necessary to accurately measure these components. A considerable amount of ammonia is present and that should be measured.

One potential solution to this dilemma is to utilize fast GC columns with a low mass in a portable GC like the PID Analyzers Model GC312. What is a FAST GC column? There are several types: One approach involves using a 25m x 0.32 mm ID, 0.25µm film thickness that is resistively heated and can be programmed at a much higher rate than conventional ovens. It can also be cooled faster since it has a very small thermal mass. This is the approach that we have taken. The detectors used would be a Far UV Absorbance detector (FUV) for carbon dioxide, methane and nitrous oxide and a PID for measuring ammonia. A complete analysis of these gases can be done in about 3 minutes. This method will provide better detection limits and more accurate results than conventional spectroscopic methods.

Accepted as a Career Development Workshop: AAAS 2019 Washington, DC
21368: Exceptional Presentations In Spite of PowerPoint: How to Communicate Your Science in the Digital Age

Session Description:
“Death by PowerPoint” is in the lexicon for good reason. Giving a great presentation is about engaging an audience, which requires understanding who that audience is and what they hope to gain by listening to you. In order to deliver a great presentation, you have to create outstanding presentation materials. How do you do this? Workshop presenters will illustrate best practices on how to communicate your science during formal presentations including webinars using storytelling and anecdotes, digital tools such as simple DIY graphics which can also be applied to science communication via social media, for informal verbal presentations and time management skills both for presentation preparation and for execution of the presentation.
Workshop Audience:

Graduate Student
Postdoctoral Scholars
High-School Teacher
College and University Faculty
Early-Career Scientist
Mid-Career Scientist
Late-Career Scientist

Audience Interest Statement:

It is essential for scientists to possess strong written and verbal communication skills in the workplace with co-workers, when communicating with other researchers for knowledge mobilization, the public using broader impacts and to an audience of other scientists. This workshop will teach scientists how to communicate their science by creating engaging, impactful and interesting presentations for use in front a live audience and for presentation planning for webinars. There will be a graphics content creation tutorial with emphasis on digital and social tools and shortcuts, various what to do/what not to do scenarios, as well as interactive group activities that will require the audience to work together in teams to compete for the title of "The exceptional Powerpoint slide" accompanied by a timed short verbal presentation.
