Jessica Stuart¹, Ruben Lopez², Jason Lau¹, Xuguang Li², Mahesh Waje², Matthew Mullings², Christopher Rhodes², Stuart Licht¹

¹Department of Chemistry, The George Washington University, ²Lynntech

A protocol is presented to study multi-electron metal/air battery systems by using previous technology developed for the zinc/air cell. Electrochemical testing is then performed on fabricated batteries to evaluate performance.

Preparation and Use of Carbonyl-decorated Carbenes in the Activation of White Phosphorus

Antonio J. Torres¹, Christopher L. Dorsey¹, Todd W. Hudnall¹

¹Chemistry and Biochemistry, Texas State University

Here, we present a protocol for the synthesis of two carbonyl-decorated carbenes. The protocol makes these interesting compounds readily available to chemists of all skill levels. In addition to the synthesis of these two carbenes, their use in the activation of white phosphorus is also described.

Non-aqueous Electrode Processing and Construction of Lithium-ion Coin Cells

Malcolm Stein IV¹, Chien-Fan Chen¹, Daniel J. Robles¹, Christopher Rhodes², Partha P. Mukherjee¹

¹Department of Mechanical Engineering, Texas A&M University, ²Department of Chemistry and Biochemistry, Texas State University

Non-aqueous electrode processing is central to the construction of coin cells and the evaluation of new electrode chemistries for lithium-ion batteries. A step-by-step guide to the basic practices needed as an electrochemical engineer working with batteries in an academic experimental setting is furnished.

¹Materials Science, Engineering, and Commercialization Program, Texas State University, ²Department of Chemistry and Biochemistry, Texas State University, ³Department of Biomedical Engineering, The University of Texas at Austin

A protocol is presented for the synthesis and preparation of nanoparticles consisting of electroactive polymers.

Chemistry

Effect of Microwave Synthesis Conditions on the Structure of Nickel Hydroxide Nanosheets

Samuel W. Kimmel¹, Vivian Kuykendall², Cole Mough², Avery Landry³, Christopher P. Rhodes^1,2

¹Materials Science, Engineering, and Commercialization Program, Texas State University, ²Department of Chemistry and Biochemistry, Texas State University, ³Westlake Highschool

Nickel hydroxide nanosheets are synthesized by a microwave-assisted hydrothermal reaction. This protocol demonstrates that the reaction temperature and time used for microwave synthesis affects the reaction yield, crystal structure, and local coordination environment.
