Antibacterial Reactivity of Ag(I) Cyanoximate Complexes

Submitted by Kari Young / Centre College on Sat, 08/22/2015 - 14:09
Description

In this experiment, students will synthesize and characterize one of three Ag(I) cyanoximate complexes as potential antimicrobial agents for use in dental implants. This experiment combines simple ligand synthesis, metalation and characterization, and a biomedical application. The complexes are both air and light stable.

Kayaking to Lake Washington

Submitted by Fabiola BL / The Cooper Union for the Advancement of Science and Art on Fri, 07/03/2015 - 00:51
Description

Leisure activity after days of hard work at the IONiC VIPEr workshop in Seattle, WA.

Participants rented kayaks and paddled around the lake for about 90 minutes.

Pre-requisites: Application of a generous amount of sunscreen.

The original plan was to paddle to Lake Washington, but no directions or map was provided. So given the lack of navigation skills and familiarity with the area it is no surprise that only one kayak made it all the way to lake Washington (Go team FBL & KMH!).

Interpreting XPS and CV data from an Electrocatalysis Publication

Submitted by Karen McFarlane Holman / Willamette University on Thu, 07/02/2015 - 20:32
Description

This is a learning object focused on analyzing a specific figure from a research article that show XPS and CV data on Ni(OH)2/NiOOH thin films that have incorporated Fe.

Peer Review - How does it work?: A literature discussion with a focus on scientific communication

Submitted by Mike Norris / University of Richmond on Thu, 07/02/2015 - 20:21
Description

This learning object is based on discussion of the literature, but it follows a paper through the peer review process.  Students first read the original submitted draft of a paper to ChemComm that looks at photochemical reduction of methyl viologen using CdSe quantum dots.  There are several important themes relating to solar energy storage and the techniques discussed, UV/vis, SEM, TEM, electrochemistry, and catalysis, can be used for students in inorganic chemistry.

Ir(III) Catalyst Regeneration Using Molecular Oxygen: Addressing Key Challenges that Hinder Alkane Dehydrogenation Catalysis. A Literature Discussion

Submitted by Vanessa / Albion College on Thu, 07/02/2015 - 15:56
Description

This Learning Object involves reading a recent scientific journal article, answering questions relating to the content, and participating in a classroom discussion. The paper under review is “Regeneration of an Iridium (III) Complex Active for Alkane Dehydrogenation Using Molecular Oxygen,” Organometallics, 33, 1337-1340. DOI: /10.1021/om401241e).

Analyzing a journal article for basic themes, roles of authors, and the scientific method

Submitted by Darren Achey / Kutztown University on Thu, 07/02/2015 - 15:03
Description

This literature discussion is meant to give students an understanding of both the key concept-driven and more “meta” information of a literature paper.  Students will use Jillian Dempsey’s paper, “Electrochemical hydrogenation of a homogeneous nickel complex to form a surface-adsorbed hydrogen-evolving species,” to investigate paper authorship, how the scientific method is used in research, and how to understand the important findings of a research article.

Exploring the Scientific Method in an Electrocatalysis Publication

Submitted by Sarah K. St. Angelo / Dickinson College on Thu, 07/02/2015 - 00:40
Description

This is a learning object focused on discussing application of the scientific method in the chemical literature. This focuses on the paper “Nickel-Iron Oxyhydroxide Oxygen-Evolution Electrocatalysts: The Role of Intentional and Incidental Iron Incorporation” (J. Am. Chem.

The Messy Chemist: Separating a Solid Mixture

Submitted by Mike Norris / University of Richmond on Tue, 06/30/2015 - 14:42
Description

This lab exercise gives students a problem scenario (a mixture of 4 solids) and asks them to determine a way to separate them from each other utilizing experimentation, previous knowledge, and discussion.  Students are expected to write a standard operating procedure detailing the method they determine for the separation at the end of the lab.  A modified version of this lab was originally performed in an accelerated summer class on chemistry given to 7th, 8th, and 9th graders that were on a track for early entrance into college.  The lab was done over the c

Use of Toulmin’s Argumentation Scheme in Explaining Inorganic Chemistry:

Submitted by Kate Plass / Franklin & Marshall College on Mon, 06/29/2015 - 14:26
Description

This is a presentation to introduce students to Toulmin’s Argumentation Scheme in the context of providing explanations in Inorganic Chemistry. It was inspired by discussions with Rick Moog at Franklin & Marshall College regarding how to encourage students to fully explain the “why” behind chemical behavior, rather than simply cite trends or equations. These slides were used to prompt a discussion about what a complete, logical explanation should include. They also served as a means of defining what is expected on quizzes and exams in response to various prompts.
