Ion Separations: Achieving Selectivity Through Rational Design In Solvent Extraction And Crystallization Systems, Neil Justin Williams
Ion Separations: Achieving Selectivity Through Rational Design In Solvent Extraction And Crystallization Systems, Neil Justin Williams
Doctoral Dissertations
The selective separation of ions from aqueous solutions has been a difficult challenge to address in the separation sciences. The difficulties associated with selective separations of ions are due to a multitude of chemical and physical differences between them. Additionally, the term ions encompass both positively charged cations and their counter parts the negatively charge anions. The work covered in this dissertation discusses the difficulties encountered during the selective separation of both oxoanions and cations. Apart from the Introduction Chapter 1 and Conclusion Chapter 10, the selective separations oxoanions and cations will be discussed separately with the dissertation being …
Structure-Property Relationships At The Nano-Bio Interface: Engineering The Nanoparticle Surface For Immunomodulation, Daniel Fernando Moyano Marino
Structure-Property Relationships At The Nano-Bio Interface: Engineering The Nanoparticle Surface For Immunomodulation, Daniel Fernando Moyano Marino
Doctoral Dissertations
Each year, a variety of novel nanomaterials are being developed with the objective of treating different diseases. However, since nanomaterials are foreign to the human body, one of the principal factors that limit their use is the encounter with the first line of defense from the body: the immune system. If this interaction is not taken into account, an undesired recognition takes place and the efficiency of nanoparticle based therapies is dramatically reduced. As such, understanding the rules that govern this recognition is of prime importance in the field of nanomedicine. Following this line of thoughts (the driving force), the …

Boron And Metal Catalyzed C-C And C-H Bond Formation, Adam Barret Pippin
Doctoral Dissertations
Research efforts focused on the use of boron and metals to form new carbon-carbon and carbon-hydrogen bonds are summarized in this dissertation. Several novel reactions have been developed. These include: the deoxygenation of benzylic alcohols using chloroboranes; alkenylation of benzylic alcohols using boron trichloride; and dialkynlation of aryl aldehydes using dialkynylboron chloride. Numerous applications of these novel reactions have been developed. These include alternate routes to diphenylmethanes and 1,4-diynes from easily prepared dialkynylboron chlorides. In addition, E and Z alkenyl halides can now be prepared using boron trichloride without the use of butyllithium. The stereochemistry of the alkenyl halide can …
