A study of the relative rates of the alkyl hydrogen abstraction
from a series of meta and para substituted t-butylbenzenes by the
chlorine atom at 70°C has been carried out. Application of the
Hammett equation yielded a ρ value of -0.44 for the para compounds.
Possible explanations for the non-linearity...
This paper describes the synthesis of t-butyl bicyclo[7.1.0]
decane-2-percarboxylate and its photolytic decomposition. The title
compound was found to undergo simple homolytic cleavage when exposed
to light of 2537 A; producing the cyclodecyl radical, carbon dioxide,
and t-butoxy radical. The largest percentage of products arose from
an intimate radical pair...
The photoelectron spectra of a series of ketone
compounds have been investigated in the gas phase. Core
ionization energies were measured to probe the effects of
molecular size and connectivity number on core ionization
energies.
It was found that core ionization energies roughly
decrease with increasing connectivity number as expected....
The development of microfluidic devices for heavy metal extraction is presented in this dissertation. Various research areas, covering subjects from photochromic compound syntheses to microchip fabrication techniques are explored to develop microfluidic devices capable of extracting heavy metal ions from drinking water. Through integration of the beneficial characteristics of both...

The development of microfluidic devices for heavy metal extraction is
There has been a tremendous growth in interest in carbon nanodots (C-dots) in the past several years. As a nascent nanomaterial, C-dots have shown great promise in applications that benefit from their superior water dispersibility, low toxicity, non-blinking fluorescent output, chemical and biological compatibility, ease of functionalization and resistance to...
Analytical chemistry is an area of chemistry primarily focused on the study and use of instruments for separation, identification, and quantification of an analyte of interest. Specifically, separation science within analytical chemistry often refers to the process of dividing mixtures into their small component parts based on differences in their...
The relative rates of hydrogen atom abstraction from a series of
13 homoaryl and heteroarylmethanes by t-butoxy radical were determined at 70°C. The attacking radical was photochemically generated
from di-t-butyl peroxide. A relatively small range of relative rates
(factor of seven) has been found among the compounds studied. The
relative...
Novel synthetic strategies are developed to prepare new intercalation compounds and nanocomposites with several layered hosts (NiPS₃, Na-montmorillonite, MoS₂ and MoO₃). In these products, alkali metals are ionic intercalates and linear polymers, dendrimers or amines act as co-intercalates. In addition to new synthetic approaches, new structures are identified and characterized....
