Dr. Gellert Mezei, Removal of anionic contaminants from water using nanojars

Zoom Event – Email edwardwthomas@gmail.com for an invite to event

Selective binding and transport of highly hydrophilic anions is ubiquitous innature, as anion binding proteins can differentiate between similar anions withover a million-fold efficiency. While comparable selectivity has occasionally beenachieved for certain anions using small, artificial receptors, the selective bindingof certain anions, such as sulfate in the presence of carbonate, remains a verychallenging task. Nanojars have emerged as a new class of anion binding andextraction agents of unparalleled efficiency. Nanojars are neutral, nano-sizedtoroidal copper(II)-hydroxide/pyrazolate assemblies comprised of a series ofhomologous oligomerization isomers of the formula [anion{Cu(OH)(pz)} n ] (Cu n ; n= 26−36; pz = pyrazolate, C 3 H 3 N 2 – ), which strongly bind hydrophilic anions such ascarbonate, sulfate and phosphate, as well as the toxic anions arsenate andchromate. By using a combination of single-crystal X-ray crystallography,electrospray-ionization mass spectrometry (ESI-MS) and 1 H-NMR spectroscopy, ithas been determined that the various Cu n nanojars are based on a combination ofthree or four [Cu(OH)(pz)] m metallamacrocycles (m = 6−14, except 11), tightly heldtogether by a network of hydrogen bonding and Cu-O interactions.Two challenging problems in the field of anion binding and extraction havebeen successfully addressed by using nanojars as extraction agents. First, nanojarsare able to extract even the most hydrophilic anions, such as carbonate andsulfate, from water into aliphatic hydrocarbons. Second, nanojars are able toselectively extract strongly hydrophilic anions in the presence of less hydrophilicanions. Moreover, rigidification of the nanojar outer shell by tethering pairs ofpyrazole ligands together leads to further increase of selectivity. Nanojarsprepared with tethered pyrazole ligands of the formula pz(CH 2 ) x pz selectively bindeither carbonate (when x = 2) or sulfate anions (when x = 3). Anion extractionstudies have shown that by using nanojars, the concentration of arsenate andchromate ions in aqueous media can be lowered below EPA-permitted levels indrinking water. Furthermore, nanojars can be used for the selective sequesteringof CO 2 from the air in the presence of other atmospheric gases by conversion tocarbonate.

Portage Green-a-Thon
2021-04-25 11:00 - 15:00
11 a.m.—3 p.m.

Environmental Awareness & Citizen Opportunities

The Green-A-Thon event is a way to raise awareness of environmental issues that affect the citizens of Portage and to provide opportunities to become more ecologically friendly. Providing a forum for such opportunities is a critical step to ensuring a sense of social responsibility in participating and encouraging “green” behavior.

Earth Day Oriented Exhibits & Games

This family-friendly Earth Day festival is open to all and includes exhibits, games and giveaways such as tree seedlings. Numerous local vendors and organizations will be present.

Exhibitor Booths & Tables

Organizations and businesses are invited to participate in this event as a way to promote themselves as environmentally conscious, provide Portage residents with an opportunity to be friendlier to the environment and educate people on the importance of “going green.” There is no charge to participate or attend. A limited number of tables and chairs are available for use, though exhibitors are encouraged to bring their own.

Contact Information & Sign-Up Form

For further information or questions, please contact Erica Eklov, staff liaison, at 269-329-4511 or at cityclerk@portagemi.gov.

Please complete the online sign-up form if you are interested in setting up a booth.

Sustainability and Green Chemistry

Abstract

With increasing public awareness of climate change, environmental pollution, and earth’s declining resources, sustainability and green chemistry have become hot topics these days. In 2015, the United Nations adopted 17 sustainable development goals (SDGs) to be achieved in 2030. As polymers are being used all around us, they play a major role in the achievement of these goals. In this talk, the speaker will provide an overview of the sustainability initiatives at American Chemical Society (ACS) and his platform as ACS President in 2021. He will also cover selected polymer research and development (R&D) areas that are related to sustainability and green polymer chemistry. The following examples will be shown: 1) to use natural renewable raw materials (e.g., polysaccharides, proteins, and triglycerides) as source materials for new chemistry and products; 2) to exploit biocatalysts (e.g., enzymes and micro-organisms) for chemical and polymer conversions; 3) to apply green chemistry concepts to conversion and processing; and 4) to develop green methodologies to promote the development of green products. In view of the relevance of sustainability and green polymer chemistry to our society, we can expect to see continued R&D and commercial activities relating to this field in the future.

KACS and Latitude 42 Supporting Project SEED
2021-02-08 18:00 | Latitude 42 – Oshtemo, Oshtemo Location 6101 W Main St, Kalamazoo, MI, 49009, United States
We are still a little hung over from last year’s celebration of the International Year of the Periodic Table (IYPT) but that won’t stop us from continuing our partnership with breweries to benefit Project SEED, which provides summer research internships for disadvantaged high school students. On March 10, we will feature a discussion by local master brewer Mike Babb of some locally produced beer styles and the brewing methods used to prepare them. We will also say a few words (short, we promise) about Project SEED and ways that you can help us support and grow our local section program. Food and beer samples (for the discussion) from the Latitude 42 menu will be provided. There is no cost to KACS members (and one guest) to attend but space is limited and an accurate headcount is important for our preparation. RSVP your name and guest’s name, if applicable, by March 1 to Doug Williams. We even have some leftover prizes from the IYPT celebrations to give away or raffle off.
