QuickCut Waterjet Cutter

The QuickCut Waterjet Cutter was created in 2019 as a senior design project. This is the third iteration of the waterjet cutter. The goal of this project was to create an operable CNC waterjet cutter that is able to cut 1/16” tensile specimens consisting of nonferrous metal or plastic. This machine will be utilized in the Manufacturing Laboratory at the University of Akron to provide education to interested students on the waterjet cutting process, how it operates, and industrial application of the technology. Waterjet cutting is a subtractive manufacturing process which is recognized for its specialized applications such as cutting dangerous materials or preserving heat treatment. Waterjet cutting utilizes high pressurized water with entrained garnet to cut through materials with precision and accuracy. The QuickCut Waterjet Cutter aims to bring the applications of industrial waterjet cutting operations to the smaller, tabletop scale to cut softer materials with precision. This report goes in depth on what defines an abrasive waterjet cutter, important components and the benefits of the waterjet cutting process. Detailed steps on how the newest rendition of the Quickcut Waterjet Cutter was created are covered. This includes brainstorming, design of components, design of controls, manufacturing process, as well as testing and future work to be completed

Shape-, size-, and functional group-selective binding of small organic guests in a paramagnetic coordination cage

A cubic coordination cage acts in MeCN as a host for neutral organic guests which contain an H-bond-accepting group that interacts with the internal surface of the cage. The different thermodynamic contributions to guest recognition and the kinetics of both guest binding and reorganization inside the cavity have been analyzed in detail by 1H NMR spectroscopy, which is facilitated by the paramagnetism of the host cage
