    "Where New Elements Come From, and How They Get Their Names"

    Friday, September 27
    at Loyola University, Chicago

    Register Now


    2019 is the International Year of the Periodic Table. Laboratories around the world work together to discover new elements, and several elements have been discovered and added to the periodic table in recent years. People love to learn about new elements and even to suggest names and symbols for them. But how are new elements named, and how are their new atomic symbols chosen? The International Union of Pure and Applied Chemistry, IUPAC, and the International Union of Pure and Applied Physics, IUPAP, collaborate with discoverers to verify claims for new elements and to recommend names and atomic symbols for them. In this talk the processes of research, discovery, verification and naming of new elements will be described.

    Safety First Minute


    The start of a new school year instantly evokes a sense of anticipation. Science teachers and chemistry instructors at all levels are busy preparing their classrooms and labs to fulfill the promise of that anticipation for students. Adopting a safety mindset is essential to guaranteeing that all students experience the wonder and excitement of learning chemistry. This month’s “Safety First” Minute reminds us that in order to maintain a safe lab and learning environment, teachers must first recognize the inherent hazards and analyze the risks for any lab activity.

    On Monday, July 1, 2019, a jury in New York City awarded $59 million in damages to a former Beacon High School student who was severely burned during a classroom demonstration involving methyl alcohol. Both the teacher and the school were found liable for this tragic accident that occurred in January 2014. News reports stated that the accident occurred when the demonstration “went awry.” However, the accident  was in fact entirely predictable. In an apparent attempt to “restart” the flame test demonstration, the teacher poured additional alcohol into a glass vessel that was still hot (and possibly even still alight) from a previous run.

    Alcohol vapor ignited upon reaching the heat or flame source, and the resulting flame “flashed back” following the stream of vapor and liquid into the large bottle of methyl alcohol. This phenomenon, known as “flame jetting,” has been documented for gasoline and other flammable liquids in a special video warning produced by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).

    The methyl alcohol classroom demonstration and similar ones involving combustion of flammable liquids have been the subject of numerous warnings from the American Chemical Society, the National Science Teaching Association, the US Chemical Safety Board, and the ATF over the past five years. Despite continued and repeated warnings from all of these agencies, accidents of this type persist with tragic regularity. Indeed, in the 12-month period immediately following the Beacon High School accident, when the safety alert warnings should still have been very “fresh” in people’s minds, six more combustion-related accidents took place across the country.

    The ACS offers numerous resources to increase the safety awareness of chemistry educators. If you will be teaching chemistry or any laboratory science course this year, please check out “Safety Guidelines for Chemical Demonstrations,” a one-page document prepared by the Safety Committee for the Division of Chemical Education. Follow these guidelines AT ALL TIMES to ensure that students will always be safe! The most dangerous thing you can do is rely on past experience to protect yourself from harm. After all, one of the things both the school and the teacher said in their defense in the courtroom in the Beacon HS case was that the teacher had done this experiment multiple times in the past without incident!

    I am grateful to the chair of the Chicago Section and its Board of Directors, including the editor of The Chemical Bulletin, for enthusiastically adopting the inclusion of “Safety First” Minutes as a best practice for our meetings and publications throughout the year. Want to suggest a topic for a “Safety First” Minute that will help support and promote our commitment to safety as a core value of the American Chemical Society? We welcome your comments, ideas, and suggestions!

    Respectfully submitted,
 Irene Cesa

    From the Editor's Desk

    As the summer comes to a close it is time for the Chicago Section to launch a new year of chemistry-themed programs and outreach activities. The section’s monthly publication, The Chemical Bulletin, is also getting a fresh start for fall.

    Let me first thank out-going editor Paul Brandt for his outstanding service to the section these past four-plus years, since March 2015, as acting editor and then as editor of the bulletin. He was also a regular contributor of articles ranging from “CHEM SHORTS” for Kids to essays of historical interest to members. Prolific is a word that comes to mind! Although Paul will be stepping into his new role as Section Chair in January, I expect to see his byline in coming issues.

    Prior to 2015 the bulletin was in the capable hands of Cherlynvaughn Bradley and Fran Kravitz, who followed a long line of editors. The first issue of this publication—which has gone by a few different names over the years—was published as Volume 1, Number 1 in March 1914. The January 2014 issue features “A Brief History of The Chemical Bulletin” (See 

    What will remain the same in the bulletin?

    Information about upcoming program-based monthly meetings will be featured prominently. We will also continue to run advertisements and to seek new ones. Josh Kurutz plans to continue his historical series, “Who Is This?” In the spirit of crowd-sourcing, readers are invited to identify individuals appearing in archival photographs in order to more fully document our section’s history. The “My Favorite Element” column will continue as articles become available, so be sure to send in your ideas. The Sidney Harris cartoons with accompanying commentary, an initiative begun last year, will continue until we have published all 12 cartoons made available to local ACS sections. The bulletin will continue to feature Irene Cesa’s relatively new column called “Safety First” Minute with a different topic each month.

    What is new in the bulletin?

    Beginning with this month’s issue, the bulletin is undergoing some changes with an eye to updating the format and sharpening some of the visuals. These cosmetic changes will soon be accompanied by new content, such as the re-running of articles from the treasure trove which is our historical archive. Josh Kurutz has been working with the science and engineering library staff at Northwestern University to make these archival bulletin issues available online. (See

    Margy Levenberg and Rebecca Weiner have been working to re-enliven the Women’s Chemistry Committee, and we will have an occasional look back at “womanpower problem” in our history and current efforts to promote women in science.

    And why not have a wee bit of humor alongside more edifying columns? Readers can look forward to an occasional chemistry crossword puzzle, to solve for fun and to share with others. I invite readers to think about other ways to introduce a spirit of collective effervescence by sending in, or creating your own, humorous entries.

    I see my role as shepherding articles, information and other contributions into an appealing and readable format that highlights the multi-faceted work of the section and invites participation. The bulletin also serves as a record of our section’s initiatives, insights and integration into the wider community at this time in our history.

    This issue of the bulletin focuses on education. Perhaps you will find something to share with a friend, family member, or scientifically minded young person considering a career in chemistry. Naturally, the contents of any organization’s newsletter represents the work of many talented individuals . . . and committees. I am grateful to those who have provided material for this issue.

    Koehler and Stoddart Named ACS Fellows

    Two out of the seventy newly named ACS Fellows are members of the Chicago Section. Dr. Michael (Mike) Koehler and Sir Fraser Stoddart are being recognized for their contributions both to the chemistry profession and to the ACS community. It seems fitting that, in the case of the Chicago Section, individuals from both industry/consulting and academia are being recognized.

    The purpose of the Fellows program, according to the ACS website (1), is to recognize and honor members of the American Chemical Society for their outstanding achievements and contributions to the science and the profession and for their equally exemplary service to the Society.

    New Fellows were inducted on Monday, August 26, 2019 during the National ACS Meeting in San Diego. They may now use the honorific designation ACSF after their names, for life.

    In making the announcement, the ACS Fellows selection committee highlighted the contributions of Koehler and Stoddart with a pair of citations for each inductee.


    Koehler obtained a BS Degree in Chemistry, Mathematics and Computer Sciences at Loyola University in Chicago and a PhD in Medicinal Chemistry at the University of Illinois Medical Center. He has been active in the Chicago Section for many years, including serving as Chair. Upon formally receiving this recognition, Mike remarked that, “It is an overwhelming honor to be recognized by my peers with the esteemed title of Fellow of the American Chemical Society. For me, it’s comparable to getting another academic degree. You walk across the stage with your family and closest friends cheering you on. You get a new title and huge expectations that you will use it to transform the world. So, as a newly minted Fellow, I’m re-energized in our mission to improve lives with the transforming power of chemistry.”

    ACS recognizes Michael Koehler “For corporate leadership as Director of Advanced Materials at Honeywell Aerospace and development of the Koehler-Hopfinger molecular modeling theories for predictions of materials properties” and “For service to the ACS Committee on Chemical Safety, the Chicago Section as Chair, Councilor and Director, and leadership in Illinois Public Policy advocacy."



    Stoddart, who is a Board of Trustees Professor of Chemistry at Northwestern University, obtained all his degrees (BSc, PhD) at Edinburgh University in Scotland. In addition to being knighted by the Queen of England in 2007, he won the Nobel Prize in Chemistry in 2016 for “the design and synthesis of molecular machines.” During 2018 Stoddart served ACS as “Champion” of Project SEED’s 50Forward campaign. Stoddart said, upon learning he had be selected, “After being a member of ACS for close on 50 years, I am chuffed beyond belief at becoming a Fellow.”

    ACS recognizes Fraser Stoddart ... “For pioneering contributions to the establishment of the mechanical bond in chemistry” and “For sharing his scientific and professional activities to inspire established and budding scientists, in novel, contemporary ways, such as though his writings, film and social media, and popular lectures around the globe.”


    Needless to say, the Chicago Section is proud of its newest ACS Fellows. Congratulations, Mike and Fraser!

    My Favorite Element


    Silicon is a chemical element with symbol Si and atomic number 14. It is in the same group as carbon, group 14. Crystalline silicon has the same atomic structure as diamond (which is made of carbon), with each silicon atom connecting to four other silicon atoms in a tetrahedral geometry. As the seventh most abundant element in the universe and the second most abundant element in the earth’s crust, silicon plays a very important role in our modern life.

    Silicon is the basis for today’s electronics, from radios and smart phones to supercomputers. This utility is a consequence, not only of its abundance, but also because of a very important property: its semiconducting behavior. When a material is a semiconductor it can conduct electricity under some conditions and yet act as an insulator under other conditions. Scientists and engineers can change the electrical property of silicon by substituting some of the atoms in its chemical structure to other atoms, a process called “doping”. This tunability makes silicon an ideal material for fabricating transistors that amplify electrical signals.

    Silicon is also a “rising star” in the field of lithium-ion batteries because it promises a significant improvement in energy density, enabling our phones and laptops—as well as electric cars—to go longer between charges. Graphite is the current state-of-the art material for the negative electrode in lithium-ion batteries. Compared to graphite, silicon offers 10 times the gravimetric capacity and 3 times the volumetric capacity. This higher capacity, however, also comes with a price. Silicon has a much larger volume change than graphite during charging and discharging, and this behavior leads to significantly shortened battery life. Scientists and engineers are currently working on improving the cycle life of silicon-containing lithium-ion batteries via innovations both on the material level and on the battery system level.

    Compounds of silicon also play an important role in daily life. Silicon dioxide, or SiO2, is the most common one. For example, beach sand is made of amorphous silicon dioxide, where the silicon atoms and oxygen atoms are arranged with short-range ordering but no long-range ordering. Silicon dioxide can also exist in the crystalline form known as “quartz”. Quartz has both short-range and long-range atom ordering in its structure. Because of the very different long-range atom ordering in the crystalline and amorphous forms of silicon dioxide, quartz has very different properties from beach sand. In fact, quartz has excellent optical properties and is widely used in the optics field. Furthermore, silicon dioxide is also used extensively for fabricating glass and bricks. Silicon dioxide gel, or silica gel, is used as a desiccant thanks to its excellent capacity for absorbing moisture. Silicon forms other useful compounds as well. Silicon carbide (SiC, or carborundum, shown) is almost as hard as diamond and is used as an abrasive. Sodium silicate (Na2SiO3), also known as water glass, is used in the formulation of cements and the manufacture of adhesives. Silicone, a class of silicon-containing polymer materials, is used in waterproofing treatments, molding compounds, mechanical seals, and high-temperature greases and waxes.

    Who Is This?

    50-year Members of 1997

    At our meeting in June, we continued our tradition of presenting awards to members for being with ACS for 50-, 60-, and 70-years. In our archives, we came across a collection of photos apparently from one of the analogous occasions from 1997. The photos are in a paper envelope labeled only with a post-it note reading “1997 50-year?” with no other annotations. We need your help deciphering who most of the people are in these pictures.

    Several of the faces in these photos are familiar, belonging to people who have served Chicago ACS into recent years. (Barb Moriarty, Margy Levenberg, Cherlyn Bradley, for instance, are shown.) It appears that, at the time, Moriarty was Section Chair, and Levenberg was Chair-Elect.

    Do you know any of the people in these photos? We have high-resolution copies in this collection (see: If you know any of the people identified with a code, such as 9706-A or 9706-5, please write to [email protected].

    Thanks for your help! And thanks to those who have helped solve previous photo mysteries, including Dolores Kenney, Steve Cohen, Margaret Schott, Milt Levenberg, and others.

    Chemistry Olympiad


    Allen Ding is no stranger to science competitions. A rising senior at Adlai E. Stevenson High School in Lincolnshire, Illinois, Mr. Ding has had a remarkable run of success during the past several years, including his time at Daniel Wright Junior High. From the fifth grade up to the present, he has applied his growing knowledge and laboratory skills in quite a number of local, regional, state and national examinations in forensic science and chemistry. Allen’s mentor is Stevenson chemistry teacher Kevin Crowe.

    As reported by Russ Kohnken in the June 2019 issue, Ding, along with fellow Stevenson student Richard Yin, was named to the High Honors list (top 50) based on their National Chemistry Olympiad Test scores. Since Allen was also one of the top 20 scorers, he was invited to attend the National Chemistry Olympiad study camp, held at the University of Maryland in College Park this past June. At the end of two weeks of intensive instruction, study and laboratory practice, four students and two alternates were selected for the U.S. team. Since Allen placed fifth, he was named first alternate, a high honor indeed.

    Allen Ding is third from the right in this photo of the U.S. national team (1).
    Peter Cutts Photography.

    According to an ACS press release (1), “The competition for the U.S. team was fierce, beginning with a multiple-choice exam taken by nearly 16,000 high school students across the country. The top 1,000 then advanced to take the National Chemistry Olympiad test.” ACS has been a major sponsor of the American team annually since the U.S. joined the Olympiad in 1984.

    Remarkably, Allen was also one of two students invited by his school to compete in the National Chemistry Olympiad Test as a freshman in 2017. When he again took the national exam as a sophomore, in 2018, he not only made the High Honors list but also the top 20. He and fellow Stevenson student Zachary Chin attended the study camp, which was held at the U.S. Air Force Academy in Colorado Springs that year.

    Mr. Ding has now participated in three high school national exams and two national study camps. He believes that, while putting in hours of studying is certainly important, the quality of believing in oneself is what leads a young person to success.

    What drew him to chemistry? Allen says it was during middle school when he began to discover that “science was more than just experiments but rather finding approaches to explain how the universe works the way it does. I zoomed in on chemistry since I often questioned the occurrences around me, from simple chemistry to the reactions in stars, and was able to find the answers through this science.”

    The Chicago Section administers and grades the local exam for students in our section, according to Kohnken. “We administer the national exam”, he said, “to the qualifiers from our section. The number of qualifiers is determined by the national office and is based on the number of members in our section.  We usually have 19 or 20 students to take the national exam from our section.” A total of 144 local ACS Sections took responsibility for administering the examination in the United States this year.

    All together, three hundred chemistry students from 80 countries and five continents earned a chance to compete in Paris this past July ( In future years the international competition will take place in Istanbul (2020) and Osaka (2021).

    Mr. Ding is set to graduate from Stevenson in the spring of 2020. It will be interesting to see where his scientific acumen and competitive skills take him in the future: perhaps he will be heading for Istanbul next summer. About that possibility he says, “It is a once in a lifetime opportunity that I don’t want to miss.”

    Sidney Harris Cartoon with Connelly Commentary

    "It is impossible to imagine what the world around us would look like without chemistry. Whether producing high-performance athletic apparel or commercializing paint with less environmental impact, chemistry is central to everything! For me, having spent much of my career at DuPont, I continue to be personally and professionally committed to DuPont’s onetime vision of making “Better Things, for Better Living, through Chemistry.” Now, leading the American Chemical Society whose mission is “Improving people’s lives through the transforming power of chemistry,” I’m inspired to see the power of innovative chemistry harnessed worldwide. I challenge those in the chemistry enterprise to follow the lead of this cartoon and clearly communicate the wonders and benefits of this central science to everyone around them."

    ~Thomas M. Connelly, Ph.D., ACS Executive Director and Chief Executive Officer

    Funded by the ACS Innovative Grant Program and hosted by the Division of History of Chemistry, eminent cartoonist Sidney Harris has agreed to provide 12 previously unpublished cartoons to ACS Local Sections for use in their news-letters and web pages beginning in January 2019. Many of his cartoons are available in the book “EUREKA! DETAILS TO FOLLOW – Cartoons on Chemistry” (2018), Sidney Harris Publisher.
