Aphasia is an impairment that affects many different aspects of language and makes it more difficult for a person to communicate with those around them. Treatment for aphasia is often administered by a speech-language pathologist in a clinical setting, but researchers have recently begun exploring the potential of virtual reality (VR) interventions. VR provides an immersive environment and can allow multiple users to interact with digitized content. This exploratory paper proposes the design of a VR rehabilitation game –called Pact– for adults with aphasia that aims to improve the word-finding and picture-naming abilities of users to improve communication skills. Additionally, a study is proposed that will assess how well Pact improves the word-finding and picture-naming abilities of users when it is used in conjunction with speech therapy. If the results of the study show an increase in word-finding and picture-naming scores compared to the control group (patients receiving traditional speech therapy alone), the results would indicate that Pact can achieve its goal of promoting improvement in these domains. There is a further need to examine VR interventions for aphasia, particularly with larger sample sizes that explore the gains associated with or design issues associated with multi-user VR programs.

This thesis is about how Fe catalysts can be degraded using photocatalysis and how Fe catalysts can degrade small molecules in conjunction with light. The goal of this paper is to look further into more sustainable methods of organic chemistry. Many current organic chemistry practices involve the use of precious metals. Iron is a more sustainable catalyst because it is abundant and inexpensive which is important for preserving the earth and making the organic chemistry more accessible. Along the same lines, light is a renewable energy source and has demonstrated its ability to aid in reactions. Overall, the goal of this paper is to explore the more sustainable alternatives to harsh and toxic organic chemistry practices through the use of Iron and light.

Augmented Reality (AR) especially when used with mobile devices enables the creation of applications that can help students in chemistry learn anything from basic to more advanced concepts. In Chemistry specifically, the 3D representation of molecules and chemical structures is of vital importance to students and yet when printed in 2D as on textbooks and lecture notes it can be quite hard to understand those vital 3D concepts. ARsome Chemistry is an app that aims to utilize AR to display complex and simple molecules in 3D to actively teach students these concepts through quizzes and other features. The ARsome chemistry app uses image target recognition to allow students to hand-draw or print line angle structures or chemical formulas of molecules and then scan those targets to get 3D representation of molecules. Students can use their fingers and the touch screen to zoom, rotate, and highlight different portions of the molecule to gain a better understanding of the molecule's 3D structure. The ARsome chemistry app also features the ability to utilize image recognition to allow students to quiz themselves on drawing line-angle structures and show it to the camera for the app to check their work. The ARsome chemistry app is an accessible and cost-effective study aid platform for students for on demand, interactive, 3D representations of complex molecules.

Amidinates and guanidinates are promising supporting ligands in organometallic and coordination chemistry, highly valued for their accessibility, tunability, and comparability with other popular anionic N-chelating hard donor ligands like β-diketiminates. By far the most powerful way to access these ligands involves direct metal-nucleophile insertion into N,N’- substituted carbodiimides. However, the majority of reported examples require the use of commercially accessible carbodiimide peptide coupling reagents with simple alkyl substituents leading to low variation in potential substituents. Presented here is the design, synthesis, and isolation of a novel N,N’-bis[3-(diphenylphosphino)propyl]carbodiimide via an Aza-Wittig reaction between two previously described air stable substrates. At room temperature, 3-(diphenylphosphanyl-borane)-propylisocyanate was added to N-(3-(diphenylphospino)propyl)-triphenylphosphinimine, leading to product formation in minutes. One-pot phosphine-borane deprotection, followed by simple filtration of the crude mixture through a small, basic silica plug using pentane and diethyl ether granted the corresponding carbodiimide in high purity and yield (over 70%), confirmed by 1H, 13C, and 31P NMR spectroscopy. In addition to accessing different central carbon substituents, modification of phosphine substituents should be easily accessible through minor variations in the synthesis. With these precursors, anionic amidinates and guanidinates capable of κ4 -N,N,P,P-coordination may be accessed. The ability of the labile phosphine arms to associate and dissociate may facilitate catalysis. Thus, this carbodiimide provides a tunable, reliable one step precursor to novel substituted amidinates and guanidinates for homogeneous transition metal catalysis.

Chemistry has always played a foundational role in the synthesis of pharmaceuticals. With the rapid growth of the global population, the health and medical needs have also rapidly increased. In order to provide drugs capable of mediating symptoms and curing diseases, organic chemistry provides drug derivatives utilizing a limited number of chemical building blocks and privileged structures. Of these limited building blocks, this project explores Late–stage C–H functionalization of (iso)quinolines using abundant metal catalysis in order to achieve site-selective molecular modification.
