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.

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.

Title: Photoredox Catalysis: An Inorganic Chemist’s View of Organic Synthesis

Register: https://zoom.us/meeting/register/tJMpfu2hpzojHdCc6A5pCxPLdpmVN0xTQzFz

Abstract: Photoredox Catalysis uses photoactive coordination complexes of transition metals to catalyze organic reactions. This strategy has enabled previously elusive transformations, opening the door to new bond disconnections and functionalizations. In the past decade or so, photoredox catalysis has been extensively studied by organic chemists around the world; the majority of these efforts is focused on the development of new synthetic methods. In-depth mechanistic studies, however, have somewhat lagged behind. This talk includes part of my work in photoredox catalysis (from the point of view of an inorganic chemist). I will also summarize some projects that go beyond method development, highlighting collaborative work by groups that integrate other branches of chemistry.
