Open Access research shaping international environmental governance...

Strathprints makes available scholarly Open Access content exploring environmental law and governance, in particular the work of the Strathclyde Centre for Environmental Law & Governance (SCELG) based within the School of Law.

SCELG aims to improve understanding of the trends, challenges and potential solutions across different interconnected areas of environmental law, including capacity-building for sustainable management of biodiversity, oceans, lands and freshwater, as well as for the fight against climate change. The intersection of international, regional, national and local levels of environmental governance, including the customary laws of indigenous peoples and local communities, and legal developments by private actors, is also a signifcant research specialism.

Abstract

A set of five coals have been electrochemically hydrogenated and changes to the chemical structure were monitored by elemental analysis and NMR. It was thought that the elemental analysis gave spurious results due to possible hydrogen trapping. The NMR clearly showed a decrease in aromatic material and the creation of aliphatics. Changes to the macromolecular structure following hydrogenation were monitored by measuring changes in: the amount of pyridine soluble material; the amount of volatile material; decrease in glass transition temperatures; and in solvent swelling. The increase in the amount of aliphatic material correlated well with the change in the amount of soluble material and decrease in glass transition temperature. A less perfect correlation was noted between the amount of aliphatic material and the amount of volatile material and no correlation was noted between increase in aliphatics and solvent swelling.
