Reductive Alkylation Reactions Using Tetramethyldisiloxane and Potassium Tert-Butoxide Via Reductive-Radical Polar Crossover
… proving the system undergoes the process of reductive-radical polar crossover (RRPC) Ultimately, the TMDSO and KOtBu reagent pair is thought to be synthetically useful in performing reactions in transition-metal-, photoredox-, and electrochemistry-free conditions, with a potentially larger …

Reductive Dehalogenation by Aqueous Biochars
… targets the reactivity of a�"BCs toward the reductive degradation of organohalogens. This Ph.D. project aims to: 1) study the degradation of organohalogen (with triclosan (TCS) as a model compound) by reduced a�"BCs; 2) investigate the impact of the chemical nature of quinones (QNs) as …

Intermetallic compounds by reductive annealing
The majority of the work described in this thesis focuses on the development of a new synthetic route to binary and ternary intermetallic compounds, which avoids the need for reaction at very high temperatures, multi-step reactions, reaction under vacuum and/or the synthesis of precursors. The …

Reductive Aspects of Thermal Physics
This thesis examines various reductive case studies in thermal physics. In particular, I argue that according to my account of reduction-as-construction, there are two suc- cessful examples of reduction. Thermodynamics reduces to statistical mechanics, and statistical mechanics reduces to the …

Unipotent representations of real reductive groups
Let G be a real reductive group and let Ĝ be the set of irreducible unitary representations of G. The determination of Ĝ (for arbitrary G) is one of the fundamental unsolved problems in representation theory. In the early 1980s, Arthur introduced a finite set Unip(G) of (conjecturally unitary) …

Dual Pairs and Disconnected Reductive Groups
… of a Lie algebra dual pair (a pair (g₁, g₂) of reductive Lie subalgebras of a Lie algebra g such that g₁ and g₂ equal each other’s centralizers in g) and the notion of a Lie group dual pair (a pair (G₁, G₂) of reductive subgroups of a reductive Lie group G such that G₁ and G₂ are each other’s …

On affine embeddings of reductive groups
… the case of affine normal embeddings of reductive groups. We might guess that as in the case of toric varieties, some specific subset of one-parameter subgroups may contribute to the classification of affine embeddings of general reductive group. To check this, we review the theory of …

The Taylor-Wiles method for reductive groups
… Galois representations ρ valued in an arbitrary reductive group Ĝ which we use to develop a variant of the Taylor–Wiles method. Our generalization allows Taylor–Wiles places for which the image of Frobenius is semisimple, a weakening of the regular semisimple constraint imposed previously in the …

The Effect of Cyclodextrin on Reductive Dechlorination
… how the addition of cyclodextrin (CD) affects reductive dechlorination of chlorinated ethenes. After chlorinated solvent degradation rates were established in anaerobic and aerobic microcosms, 100 mg/L of CD solution was added for a period of 21 days. CD was then removed after 26 days to …

Reductive metabolism of aliphatic tertiary amine n-oxides.
This study is based on a proposal concerning the feasibility of using aliphatic tertiary amine N-oxides as antiarrhythmic agent prodrugs. Lignocaine was selected as a candidate for prodrug development, because the N-oxide is a non-active, polar derivative of lignocaine and the drug of choice for …

Alkylation of Boron Nitride Nanomaterials using Reductive Conditions
Boron nitride nanomaterials possess an unparalleled combination of properties: their mechanic properties are superior to that of steel, their thermal conductivity is comparable to that of copper, their band gap is that of an insulating material, and their chemical and thermal stability is …

Consciousness and reductive explanation : has materialism been refuted?
… has it that because consciousness is not open to reductive explanation (consciousness is not logically supervenient on the physical), materialism, which is committed to a priori conceptual analysis, must be false. In this thesis, an attempt will be made to discredit this viewpoint. While Ned Block …

Toward the photo-induced reductive elimination of halogens
… metal dimers as potential platforms for the reductive elimination of halogen. Early transition metals were explored with bis(alkylamido)phenylborane ligands. These systems did not demonstrate halogen elimination, but an interesting transition metal chemistry was developed for this ligand set. …

Reductive Alkylation of Proteins Towards Structural and Biological Applications
… nuclear magnetic resonance spectroscopy (NMR). Reductive 13C-methylation is an alternative labeling method for proteins not amenable to bacterial host overexpression. Because reductive 13C-methylation adds sparse, isotopic labels, traditional methods of assigning the NMR signals are not …

The reductive animation of ethanol using supported metal catalysts
