On Chemical Structure [PDF]

Proceedings of the Royal Society of Edinburgh
In this paper the author drew attention to the nature of the process of Chemical Exchange (including substitution, double decomposition, and some cases of direct addition and subtraction), as a process by which the number of relations in which any given atom stands is unaffected.

A combined AFM and Fourier Transform analysis approach for quantifying surface microstructure evolution in PAN-based carbon fiber processing

Giant
Surface defects, particularly longitudinal grooves, significantly limit the mechanical performance of carbon fibers (CFs). While these defects are often inherited from precursor fibers, quantitatively tracing their multi-scale evolution throughout the ...

The Chemical Structure of Bisteroids

THE JOURNAL OF VITAMINOLOGY, 1968
It was found that the “bisteroid” previously reported is a mixture of two components (compounds A and B) and that compound A is a substance having the molecular formula C54H84 and compound B is a monoacetate having the molecular formula C56H88O2. The molecules of compounds A and B seem to contain at least two double bonds.
