National Chemistry Week

NATIONAL CHEMISTRY WEEK
OCTOBER 18-24
The theme of this year’s National Chemistry Week is Chemistry Under Construction — exploring how chemistry improves the strength, safety, sustainability, and durability of everyday materials like concrete, steel, and glass. Educational resources on construction materials, as well as the Illustrated Poem Contest for students in grades K–12, are available at the NCW website. Outreach coordinator Sherri Rukes of the Chicago Section has written an activity entitled “Using Candy to Learn About Making Fractures” for the current issue of Celebrating Chemistry (downloadable as a PDF).

National Chemistry Week (NCW) is a public awareness campaign that promotes the value of chemistry in everyday life. ACS members and chemistry enthusiasts celebrate NCW by coordinating events and communicating the importance of chemistry. The mission of NCW is to reach the public, particularly elementary and secondary school children, with positive messages about chemistry to make a positive change in the public's impression of chemistry, promote a mechanism for effectively mobilizing ACS local sections, and motivate ACS members through local section activities.

Award Winner

Chad Mirkin Awarded
2027 Priestley Medal
The American Chemical Society has selected Chad A. Mirkin of Northwestern University to receive the 2027 Priestley Medal, the Society’s highest honor, for his “pioneering contributions to nanochemistry and for impacting the chemistry profession globally through innovations in education, service, and policy at the highest levels, and entrepreneurship.” According to Joe Francisco, a past President of ACS, “Professor Mirkin has transformed the landscape of nanostructured materials, redefining how chemists design, build, and deploy them across diverse scientific and technological domains. I can think of no one more deserving of this honor.”

In 2025 the Chicago Section recognized Mirkin with the Willard Gibbs Medal for his world-leading accomplishments. He was also named a Kavli Prize in Nanoscience laureate in 2024. Mirkin is one of the few individuals to hold memberships in all three National Academies—Science, Engineering, and Medicine. Mirkin's life story, "Living Large Studying the Small", can be found at the Kavli Prize website.

Letter from the Chair

Are You a Lifelong Learner?
Were you at the ACS Fall 2026 Meeting in Chicago? Did you learn something new about the chemical history of Chicago? Did you take a picture with Alice Hamilton at our booth? Did you admire the beauty of Lake Michigan?
Thank you to all who attended, presented and volunteered to create a spectacular impression of our Chicago Local Section and city. At a time when ACS seeks to improve its connection with the local sections, your involvement at the Fall ACS meeting—whether speaking at our Sunday symposium about historical chemistry contributions, writing articles for The Chemical Bulletin newsletter, interacting with ACS members, visiting the Chicago booth in the Local Section Row at SciMix, or welcoming people at our section’s booth in the Membership Lounge—demonstrated the strength, creativity, and enthusiasm of a model section. Congratulations! I am particularly impressed with our efforts to reach out to the younger chemists.
Regardless of our age, ACS members are lifelong learners, who voluntarily continue renewing their knowledge of chemistry and the world.
The 150th anniversary theme of this month, lifelong learning presents us with the challenge to participate in discussions of great magnitude, such as the use of AI; the ability to safeguard people and our earth through green chemistry; or the capacity to remain a viable contributor to our knowledge base and its containment. As the world changes at great speed, lifelong learners keep an informed pace with the growing body of science, remain confident that chemistry will continue as the backbone of these incredible changes, and serve as satisfied and profitable members of society. Your participation in the ACS meeting demonstrated that you value lifelong learning. Continue to challenge yourself. You are doing great.
Please consider extending your impact on chemistry and our local chapter by becoming an officer. We need your valuable insight and enthusiasm to grow even stronger.
—AMY BALIJA
Special Feature

Chemistry Quiz Online
Do you enjoy challenging yourself by taking quizzes? In preparation for the Fall 2026 National ACS Meeting, Chair Amy Balija authored questions for use at the Chicago Section’s welcome booth. Milt Levenberg created the software application. As Milt noted, “It would be great if some of our readers enjoyed taking one of the quizzes and the project didn't just disappear once the Chicago Fall National Meeting ended.” The quiz can be found by going to the ACS/State Fair area of our chicagoacs.net archival hosting site and selecting “Chemistry quiz for serious students” on the left sidebar, or by using the QR code, or via the direct link: https://chicagoacs.net/statefair/ACS_Quiz/index.html. There is a large variety of questions, and participants see a different subset of them every time he/she enters the quiz. In addition, quiz-takers have the option of selecting questions from the “Chemistry Student” or “Science in Chicago” categories. Why not give it a try?
Sample question: Argonne National Laboratory researchers developed the widely used NMC battery cathode material. What does NMC stand for?
Awards

Amy Balija named ACS Fellow
Chicago Section Chair Amy Balija was one of 59 newly named ACS Fellows celebrated at a special ceremony hosted by ACS President Rigoberto Hernandez during the Fall 2026 National Meeting in Chicago. Fellows are ACS members who have made outstanding achievements and significant contributions to science, the chemistry profession, and the broader community. A listing of the 2026 Class of ACS Fellows can be found in the July 27 issue of Chemical & Engineering News.

Reflections on the
Activities of August
Welcome to Volume 113, issue number 8 of The Chemical Bulletin as we head into the fall. Regular readers will have noticed that last month's special issue, published to coincide with the Fall ACS National Meeting, was full of historical insights and information as well as chemistry-themed puzzle challenges. If you haven’t already seen the August/September issue, please visit chicagoacs.org and select the News menu at the top of the page.
In the current issue we celebrate awards received by Chicago Section members, namely, Chad Mirkin (Priestley Medal), Amy Balija (ACS Fellow), Ilana Lemberger (Emerging Star Award), and Ana Clara Z. Leal (ACS Leadership in Mentoring Award). Regular columnist Paul Brandt brings into view a battery-themed ChemShorts experiment, Mark Cesa reports on the work of the ACS Council, and new contributor Abdul Motakabber Sarkar reflects on his first-time participation at the national meeting. Also included in these pages are many images from recent events that were taken by Mark Zhen, the Younger Chemists Committee, Abdul Motakabber Sarkar, and Ilana Lemberger. Can you spot the historical figure Alice Hamilton who “attended” the meeting?
August was a busy month, with many members contributing to the success of the Chicago Section Welcome Booth and other events such as the Industry Panel and the table at Section Row. A big thank you to Office Manager Josie Alexander and her family members for going above and beyond the call of duty, and to Chair Amy Balija for spearheading so many creative initiatives that drew crowds seeking information, entertainment, and of course the hundreds of give-aways.
Looking for chemistry swag for yourself or others? Please refer to page 11 for examples of science-themed merchandise created by Professor Dennis Cao (Macalester College). His website features organic chemistry and NMR design motifs, among others. Professor Christian Diercks (Scripps Research) will be giving an online talk as part of the Front Row lecture series (also on page 11). Both Dennis and Christian were formerly members of the Chicago Section as students in the research group of Professor Fraser Stoddart. I hope you enjoy reading this issue.

STUDENT REFLECTION
From Monosol to McCormick Place:
My ACS Fall Experience
This past July, I attended a Chicago Section event for Younger Chemists, which consisted of a Lab Tour and Networking event at MonoSol—a company that focuses on “high-performance materials engineered to work with nature and help reduce environmental impact”, according to their website. At that event, I was thrilled to win a complimentary ACS Fall 2026 National Meeting registration and an ACS membership through the YCC giveaway.
The Fall 2026 National Meeting took place August 23–27 at McCormick Place in Chicago, bringing together chemists and researchers from around the world. The meeting featured technical sessions, keynote events, the Expo, networking opportunities, and career development offerings—something for every stage of a chemistry career.

Abdul at the ACS Fall 2026 meeting display
A major highlight was the ACS150 JACS Symposium Series: Chemistry is Everything, which showcased talks by Nobel Laureates Prof. Carolyn Bertozzi, Prof. Stefan Hell, Prof. Jack W. Szostak, and Prof. M. Stanley Whittingham. Their insights into the power and impact of chemistry were truly inspiring and thought-provoking.

Banners welcoming ACS meeting attendees
Beyond the science, I was grateful for an opportunity to volunteer with the Chicago Local Section during the meeting. It was a meaningful way to give back, support the chemistry community, and connect with professionals who share a passion for advancing our field.

Volunteering at the Chicago Section welcome booth
Winning the meeting registration giveaway was a turning point, allowing me to experience the ACS Fall 2026 meeting, expand my network, and explore cutting-edge chemistry. YCC also paired me with Professor Amartya Chakrabarti (Dominican University), whose guidance throughout the conference was highly valuable. I am grateful to YCC and the Chicago Section for this opportunity.
—Abdul Motakabber Sarkar
Abdul is a Ph.D. candidate in the chemistry program at the University of Illinois Chicago, working on advancing molecular electrochemistry for sustainable catalysis.
“Receiving the YCC giveaway allowed me to fully experience ACS Fall National Meeting, expand my network, and grow as an early-career chemist.”
- Abdul M. Sarkar

Chemistry Humor

A Collection of Colloid quips
This past June, your editor had occasion to give the plenary lecture at the ACS 100th Colloid and Surface Science Symposium at the University of Delaware. In the course of preparing for the event, a number of humorous texts and anecdotes were discovered in books, journals, and archival issues of The Chemical Bulletin and The Catalyst (Philadelphia). A colloid is a type of mixture where microscopic particles of one substance are evenly suspended inside another substance, with particle sizes typically ranging between 1 and 1,000 nm.
Everybody was talking colloids at the Urbana meeting. A glass chemist, a glue chemist, a milk chemist and a rubber chemist lunched together and began to feel they were not strangers. As a border-line science, colloid chemistry offers all the thrills of the most speculative.
How doth the little busy bee
Improve each shining hour?
By physics and by chemistry
We learn to know its power.
How doth the little silkworm win
Its product from the tree?
Because it is proficient in
Its colloid chemistry.
The use of the word ‘“colloid" is at present being made an excuse and a catchword in the chemistry industry and elsewhere, the uninstructed public having heard so much recently of progress in colloidal chemistry that any new project connected or presumably connected with it attracts undue attention.
My 4-year-old son remarked, while eating his cone, “Daddy, this ice cream hasn’t enough gel in it. It is gritty. The man who made it studied the wrong book in college.”
A parody by Jerome Alexander on the Major-General’s song from the operetta Pirates of Penzance by Gilbert & Sullivan. For lyrics see the February 2026 bulletin issue. Here are the last few lines just for fun:
You’ll find in matters vegetable, animal, and mineral,
The colloid chemist proves (s)he is the modern Chemist Gineral.
What this country needs is a good, active Society for the Suppression of Advice. Lots of good advice goes wrong, gets colloided into proverbs and things that make it sound good enough to take three times a day before meals. If you fall for that sort of stuff, there’s no hope for you, so we ought to have a really activated catalytic society to stop it.
Most of us become acquainted with the soap bubble at an early age. Its form and ease of manufacture appeal to our nascent sense of workmanship … The soap film is too often considered merely as a slab of soap solution in two dimensions only and, hence, as a dispensation of Providence for the demonstration of surface tension.
The meetings of the National Puzzlers’ League and those of the American Chemical Society [in Rochester] overlapped for a few hours, and the league posted its greetings in the following anagrams, both of which spell out the words “The American Chemical Society.”
I LAITY CAN CHEER ATOMIC SCHEME
OH SCIENCE MAY IT TEACH MIRACLE
Puzzlers who got into the Division of Colloid Chemistry by mistake soon realized that they were over their depth and returned quickly to the relative simplicity of cryptograms and magic squares. On the other hand, [the] colloid chemists are reported to have felt so at home in the fogs of puzzledom that it was only after the puzzlers adjourned that they learned they were in the wrong meeting. In spite of defections to the puzzlers convention, colloids played to standing room only and had to be moved to larger quarters.
Equally valuable is the focusing of attention on the mesoscale, the traditional regime of colloid science, as a locus of new phenomena made possible by relative liberation from both gravity’s enervating tug and heat’s crazy battering.

Coin Voltaic Pile
Batteries are used for so many applications. The technology has improved immensely but we can do better and many people are working on it. A landmark experiment performed by Alessandro Volta in 1800 achieved the very first battery. This is a fun experiment to reproduce a battery with everyday materials but you will need a multimeter to see the voltage that is achieved.
Materials:
- 3 nickels and an equal amount of pennies
- Paper towel
- Aluminum foil
- Multimeter
- Vinegar
- Salt
- Cup
Experiment:
You need clean coins to start, so mix ¼ cup or so of vinegar with roughly 1 tablespoon of salt in a cup and then add the coins. Stir these around for about a minute. Remove the coins followed by a rinse in tap water and then set them off to the side to dry. Tear off a piece of aluminum foil about two inches wide and fold it in half lengthwise and then in half widthwise and then in half widthwise again so that it is roughly 3 inches long and 1 inch wide. Put a penny on the edge of the foil. Tear off a small piece of paper towel about the size of a quarter and fold it several times so that it will fit on the penny but not go over the side. Add a few drops of the vinegar solution to the towel. Place a nickel on the wet towel. This makes a single voltaic cell.
Using the multimeter, turn it to DC voltage (2 V or 200 mV). Place one of the probes on the foil and the other probe on the nickel. If you get a negative voltage, switch the probes. Apply different pressures with the probe to see what happens to the numbers on the meter. A fairly hard press should give a fairly stable reading. If the reading jumps a lot or gives a 0.0 reading, it may be that you have too much solution on the towel and it is dripping and short-circuiting the cell, or the towel is overlapping onto the surface below.

Photo showing how to use a multimeter to measure voltage in this coil battery experiment
Repeat the process making another cell by sandwiching another penny, wet towel, and nickel. Set this on the aluminum foil and determine it’s voltage. Stack one cell on the other by placing the penny of one cell on the nickel of the other cell (no towel between them). Test the voltage of the two combined cells. Did the two voltages add together to give a combined voltage? Keep repeating until you run out of coins – but always end with a nickel on top.
What’s Happening?
The battery operates by electrons moving and the multimeter detects this as a voltage. A typical AAA, AA, C, or D cell battery is a 1.5 V battery. It would take a lot of pennies and nickels to get that many volts! Because a nickel is actually made from nickel and copper and the penny has an outside coating of copper, electrons move from the nickel (negative anode) to the penny (positive cathode) giving a voltage. By combining multiple cells as in this experiment, you are creating a series of cells which adds the voltages.
Extension:
Do pre-1982 pennies give different voltages than newer pennies due to their copper content? What happens if you use other coinage (dimes and quarters)? Can you get greater voltages using copper and zinc washers? Can you get an LED light bulb to light up?
