National Chemistry Week 2022, “Fabulous Fibers: The Chemistry of Fabrics,” saw LVACS participate in the Migrant Education Program's Annual 'Lights On Afterschool' Educational Activities & Health Fair October 18th, host a special Mole Day (well, it was actually the 20th!) pizza party at Lehigh University featuring speaker Crystal Chu presenting "Bioinspired Fibrous Materials for Medicine" and sponsor an outreach event on Saturday, 22nd, with Spring Township Parks and Recreation, Sinking Spring, PA. Rayon rhymes? Take a look at what our LVACS poets did with the NCW theme! See the summary as published in the November Octagon Newsletter.

Our October 5th meeting at Albright College brought speaker Kathryn Riley of Swarthmore College to address the members on the topic of "Advances in Nanometrology: From Engineered to Incidental Nanomaterials." The unique properties of engineered nanomaterials (ENMs) have enabled their increased use for a range of environmental, medicinal, and commercial applications. However, the uncontrolled release of ENMs into the environment (e.g., through human waste repositories) can have detrimental impacts. Her talk explored the development and application of several in situ analytical techniques, including capillary electrophoresis and electrochemistry, for the analysis of engineered and incidental NMs and their physicochemical transformations.

Kudos all around! Here's the story as it appeared in the October Octagon Newsletter.

The Lehigh Valley Local Section won FOUR (4) Chemluminary Awards at the ACS Fall 2022 Meeting! This was a clean sweep of the categories for which LVACS was a finalist as summarized in a Summer 2022 Octagon article. No cakewalk this - we were up against some stiff competition from larger sections (Midland, Silicon Valley, et al). The activities/events awarded are representative of the breadth of media/formats LVACS uses to engage its members and the community. JOIN US! All it takes is a love of Chemistry and a few hours of your time. CONTACT Nigel Sanders, LVACS Secretary 

A small but vibrant LVACS group sampled the wines of Sorrenti Family Estates in Saylorsburg, PA on July 16th to celebrate summer and the 95th Anniversary of the Women Chemists Committee. Hopefully, we'll all feel more like socializing when we put nagging viruses to rest. Thanks to LVACS WCC Chair Lorena Tribe for organizing!

LVACS had a VERY PRODUCTIVE Strategic Planning Retreat that was hosted at Cedar Crest College June 11-12. The planning group dedicated a day and a half to the creation of goals and strategies to engage, educate, and provide value to our Lehigh Valley local section's members. However, their work does not stop here! The Champions who have been identified for each of our projects should in the very near future be creating timelines for their approach. Then, the fun begins! ALL LVACS members will be asked to join in to view the plans, make suggestions and participate on the action teams. Chair Lindsey Welch and chair-elect Steve Boyer will be ushering this strategic plan forward. We were fortunate, once again, to have the capable guidance of Carol Duane and Amber Hinkle of ACS to help us develop strategies to move our section forward with strategic goals and projects to be implemented over the next 3-5 years. See the Strategic Planning page for all the details of the new plan!

The 95th Anniversary of the Women Chemists Committee (WCC) was celebrated at Reading Science Center (RSC) on Wednesday, May 25th with a special exhibit and talk on the Sisters-in-STEM program. Sarah Troy, aka Solar System Sarah, introduced a workshop on the program for 4th and 5th graders in the greater Reading area. With the vision to "Empower young women & they will change the world," Sisters-in-STEM aims to excite, encourage, educate and foster a love for science in young girls. Building this foundation of love for science will inspire each girl to want to continue their education in STEM related courses, eventually leading to more women in STEM jobs. CONTACT our LVACS WCC Chair, Lorena Tribe, for more info.

LVACS celebrated Earth Week in many ways including a special event at Da Vinci Science Center in Allentown on Saturday, April 23rd. "THE BUZZ ABOUT BUGS: insect chemistry" was the theme as about 50 kids and their parents did hands-on demonstrations of cochineal scale insect (carmine) dye extraction, insect spectral/faceted vision, aroma matching and more! Many thanks to Jennifer Pors of Da Vinci and all of our volunteers: Nigel Sanders, Jane Bedell, Philip Elias, Jade Marshall, Zoe Monogan, Faith Candelora, Erica Nemitz, Savannah Labukas and Maximus Garganta. Super job team!

Nearly 60 members attended the April 11th meeting featuring our annual undergraduate research poster session, our graduating seniors who have shown exceptional chemistry aptitude over their academic careers and a great talk by Dr. Joe Bennett of UM/BC. Here's the Program with the Poster Abstracts and the story as reported in the May 2022 Octagon Newsletter. 

Our March 10th meeting at Muhlenberg was our first truly face-to-face meeting in 2 years! A small but cheerful bunch gathered in Muhlenberg's Seegers Union to enjoy the evening with dinner and a fascinating talk by Dr. Lauren Zarzar of Penn State, "Color from Colorless Materials," which was also offered remotely via Zoom. In this lecture, Lauren explained why interference (structural) color can arise from even microscale structures (~ 100 microns) by Total Internal Reflection, such as when water droplets of different sizes form by condensation on a clean, low energy surface. Join the lecture on our YouTube channel, LVACS

On Friday, February 18th the LVACS section co-sponsored a PRIDE in STEM panel discussion held at East Stroudsburg University and online.

During our November 18th Virtual Meeting, Chip Nataro of Lafayette College, spotlighted the recent work of the The Interactive Online Network of Inorganic Chemists (IONiC), a community of transformation dedicated to improving the teaching and learning of inorganic chemistry. From how to Zoom to developing remote laboratory experiences, IONiC has been helping countless members get through the Pandemic offering students the best experience possible given the circumstances. As shutdowns remained, the leadership of IONiC developed a way to keep the community engaged via a biweekly series of presentations/discussions: Supporting Learning with Interactive Teaching: A Hosted, Engaging Roundtable or SLiThEr. Chip's presentation covered some background on the IONiC community, the development of the SLiThEr series and provided a sneak peek into some of the interesting things learned along the way. View the recording here.

Lee Silverberg, LVACS member and associate professor of chemistry at Penn State Schuylkill, has recently published a peer-reviewed paper on a novel method he has devised to create organic compounds that have demonstrated antiparasitic properties. Until this research was conducted, the structure of the starting material used to synthesize the chemical compounds was unknown. Read the full article.

Volunteers from the Lehigh Valley Section celebrated Mole Day 2021 with visitors to the Da Vinci Science Center on October 23^rd (when else?) with exhibits and demonstrations illustrating this year’s National Chemistry Week theme, “FAST/OR SLOW…Chemistry Makes It GO!” The group, consisting of representatives from across the section area, presented the importance of chemical kinetics and catalysis to approximately 100 parents and kids by showing how heat, concentration and catalysts/inhibitors affect chemical reaction rates. Read the report here. LVACS thanks Jennifer Pors and the Education staff of DSC for generous support of this event!

Lehigh Valley Section extends its congratulations to Prof. Chip Nataro of Lafayette College on winning the 2022 ACS Award for Research at an Undergraduate Institution.

The year 2020 was an exceptional one for so many reasons. Planning and running events to offer members some sense of continuity in local section activities was a challenge to say the least. The ACS ChemLuminary Awards Committee has recognized our section as finalists for two events which ‘bridged the COVID-19 gap’ in bringing chemistry content to members and the community during pandemic. See the Summer 2021 edition of the Octagon Newsletter for more details. The date and format of the ChemLuminary Awards Ceremony has not yet been set but be sure to root for us to win ChemLuminary Au once again this year!

Lehigh Valley Section is incredibly pleased to be able to congratulate Dr. Marsha Baar of Muhlenberg College as the 2021 E. Emmet Reid Small College Teaching Award winner for the Mid-Atlantic Region! Already honored with this year's LVACS Small College teaching award, this regional ACS award places Marsha in the company of an elite group of undergraduate educators. The award was presented at the virtual #MARM2021 on Thursday evening, June 10th. 

Our May 18th Section Meeting took a virtual approach to our traditional May Social with a fun and informative look at the Chemistry of Cheese and cheesemaking provided expertly by Jeanne Berk of Cedar Crest College. As we separately nibbled on a selection of cheeses (and accompaniments in some cases!), Jeanne explained how those products are made from milk (cow, sheep, goat, whatever...) and why they have the unique combination of textures and flavors which they do. The video recording may be found on our YouTube channel. Also, don't miss the May 2021 edition of the Octagon Newsletter! Stay tuned for announcements of future events as we finally put COVID-19 behind us!

On Monday, May 3rd we were informed that our pilot virtual SEED Project has been approved by ACS! Congratulations to mentor Lorena Tribe, PSU/Berks for an awesome proposal and to Jeremy Heyman, LVACS SEED Coordinator, for guiding the application. The program will support two SEED students over this coming summer. Other students have applied for the virtual camp program: more to come. See our Diversity page for more on Project SEED.

In this second year of the COVID-19 pandemic, LVACS presented a CCEW virtual panel discussion on Tuesday, April 20^th focusing on how our members are “reducing their footprint through chemistry” by making individual choices that contribute to a more sustainable world.

NEWSFLASH! LVACS has won another ACS ChemLuminary Award! These annual awards recognize special achievements by the local sections, divisions, international chapters and regional meetings. Once again, Lehigh Valley Section has received such an honor with ACS recognizing us for “Most Creative & Innovative Use of the CCEW Theme” in its 22^nd Awards Event December 9^th 2020. As you may recall, 2019 Chemists Celebrate Earth Week had the theme: ‘Take Note: The Chemistry of Paper’ which LVACS interpreted for the local community via a multi-media event at Da Vinci Science Center, co-sponsored by Minerals Technologies Inc., a worldwide supplier to the paper manufacturing industry. The Octagon reported on the event in its January 2020 issue (www.lvacs.org/Octagon-Newsletters). We illustrated the chemistry of paper through hands-on papermaking, exhibits of the wide variety of paper grades and testing equipment used to qualify them, video feeds of the papermaking process and presentations on the history of paper - a material that has changed human communication over two thousand years! Thanks to Sherman Cox of Minerals Technologies Inc., Lindsey Welch, our CCEW Coordinator and Nigel Sanders for running this award-winning event!

It was a beautiful, if chilly, day outside of Da Vinci Science Center on Saturday, October 17th as we kicked off National Chemistry Week 2020 with a few sticky reminders about the chemistry of adhesion! Jeanne Berk and Nigel Sanders demonstrated tack and adhesive strength of several common types of tape while a somewhat familiar punny bovine advocated "Use Mor Casein" (for glue) instead of synthetic variants. Berks Chapter sponsored a resume workshop, Halloween Chemistry for kids and Slime Time Online [in cooperation with the Reading Science Center, the Cape Cod Science Cafe and STEM Journey]  ...so what did U do for NCW this year? Let us know!

25 members tuned in for our Thursday, October 15th meeting with speaker Lorena Tribe of Penn State/Berks, providing some answers to: “Where will all of the CO₂ go?”. Employing computer modeling techniques, Lorena discussed simulations of the thermodynamic of interactions between CO2 and the clay minerals kaolinite and montmorillonite. So where did the CO2 prefer to go? Read all about it in the upcoming November issue of the Octagon Newsletter.

It's Fall already, the leaves are turning and LVACS has just issued a newsy October edition of the Octagon including upcoming section events, plans for celebrating NCW and our newest feature which highlights prominent chemists in LVACS history, penned by Dr. Roger Egolf of PSU/LV.

Our first meeting of the 2020-2021 year at the Da Vinci Science Center September 17th was a socially-distanced success! 35 members gathered for a tour of the BRICKLive-Ocean outdoor exhibit, brief talks by Da Vinci staff about our community outreach partnership, presentation to LVACS of Da Vinci's Grand Maestro Award and future expansion plans for the Center, followed by our LVACS awards presentation, delayed from the spring.
