Many different aspects of the determination of dissolved oxygen
by controlled potential coulometry were investigated to find a means
of measuring the oxygen content of natural waters. Rapid
sampling techniques, simplicity of operation, and rugged structural
features were stressed. Cells were designed to operate by either
internal electrolysis or external...
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...
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...
The (±) 8,9:13,14-diseco-norestradiol, a large ring hormone
analog, and its related derivatives, were prepared by a ring expansion
approach. The key step of this approach is the establishment of the
benzocyclododecenone system via the Caubere reaction. This step
not only provides a favorable ring size, it also sets the necessary...
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...
