Synthesis of Arborescent Amphiphilic Copolymers
(University of Waterloo, 2013-01-25)Living anionic polymerization techniques were applied to the synthesis of arborescent (dendritic) well-defined graft polymers having core-shell morphologies, with a hydrophobic core and a hydrophilic shell. Cycles of ... -
Synthesis of Arborescent Copolymers Based on Poly(γ-benzyl L-glutamate)
(University of Waterloo, 2013-04-26)The synthesis of arborescent poly(gamma-benzyl L-glutamate) (PBG) molecules was achieved through successive grafting reactions of linear PBG chains. These linear PBG building blocks were obtained by the ring-opening ... -
Synthesis of Arborescent Polybutadiene
(University of Waterloo, 2012-08-10)Arborescent polymers are characterized by a tree-like architecture and a high branching functionality. This type of polymer can be synthesized by different techniques, but the ‘grafting onto’ method is attractive because ... -
Synthesis of carboxylated derivatives of poly(isobutylene-co-isoprene) by azide–alkyne “click” chemistry
(Springer, 2018-09-28)The synthesis of carboxylated derivatives of poly(isobutylene-co-isoprene) (isobutylene–isoprene rubber, IIR) with substitution levels ranging from 1 to 4 mol% and different spacer lengths was accomplished through azide–alkyne ... -
Synthesis of Cyclodextrin-Complexed Metal Carbonyl Polymers
(University of Waterloo, 2016-08-10)The synthesis of metal carbonyl (MC) polymers has been explored for decades, but well-defined and well-characterized MC polymers are rarely reported mainly due to the chemical instability of MC complexes. To address this ... -
Synthesis of Deuterated Benzene for a Circular Deuterium Economy
(University of Waterloo, 2024-04-30)Deuterium is an important natural isotope; its unique properties can impart significant effects on molecules with emerging applications across electronics and medicinal industries. Aromatic hydrocarbons or arenes are one ... -
Synthesis of Inhibitors of Steroid Sulfatase and Towards the Synthesis of a Chiral Electrophilic Fluorinating Reagent
(University of Waterloo, 2007-02-02)Steroid sulfatase (STS) catalyzes the desulfation of sulfated steroids such as estrone sulfate to the corresponding steroid such as estrone. Inhibitors of STS are believed to have potential for treating estrogen-dependent ... -
Synthesis of Molecularly Defined Conjugated Oligomers and Polymers through Dehydrative Coupling
(University of Waterloo, 2019-08-21)The development of scalable methods for the synthesis of conjugated materials remains among the most important aspects for their integration into devices at a commercial level. Drawing inspiration from nature as well as ... -
Synthesis of Multiply Deuterated Cephalosporins
(University of Waterloo, 2014-12-12)Antibiotics are one of the greatest accomplishments in the field of science. They have been extensively used since the time of their discovery. Amongst all the antibiotics, the -lactam class of antibiotics have been the ... -
Synthesis of New Magnetic Nanocomposite Materials for Data Storage
(University of Waterloo, 2012-08-09)The confinement of magnetic nanoparticles (Prussian blue analogues (PBAs) has been achieved using mesostructured silica as a matrix. The PBAs have the general formula AxMy[M'(CN)n]z, where A is an alkali metal cation; M: ... -
Synthesis of Nucleoside Polyphosphates and their Conjugates
(University of Waterloo, 2014-01-02)Nucleoside polyphosphates and their conjugates, such as nucleoside triphosphates, nucleoside tetraphosphates, sugar nucleotides, dinucleoside pyro- and higher order polyphosphates, 2’,3’-cyclic nucleoside monophosphates, ... -
Synthesis of Phosphate-Crosslinked Starch Nanoparticles for Drug Delivery
(University of Waterloo, 2017-04-25)Drug delivery agents for chemotherapy drugs have gained significant interest over past few decades due to the need to localize the treatment to cancer cells. So far, polymeric micelles, liposomes, and carbon-based ... -
Synthesis of Polylactide-block-Poly(L-Lysine) Block Copolymers
(University of Waterloo, 2018-03-06)Polylactide (PLA) is an important biodegradable, biocompatible and renewable material that has been studied for many years for biomedical applications such as tissue scaffolding and surgical sutures. The research project ... -
Synthesis of Polyynes by Femtosecond and Nanosecond Laser Interaction with Matter
(University of Waterloo, 2018-10-24)A review of literature including some history and previous work done in the field is done showing the importance of polyynes themselves and as an important precursor in the formation of other interesting carbon nanoparticles ... -
The Synthesis of Sulfated Carbohydrates Using a Sulfate Protecting Group Strategy
(University of Waterloo, 2010-08-31)Sulfated carbohydrates play key roles in a wide range of biological processes such as blood clotting, viral entry into cells, amyloidogenesis, neurite outgrowth, tumor growth and metastasis. However, their synthesis still ... -
