The interaction of hemin with chloroquine, quinine and quini-dine wasinvestigated in 50% water-propylene glycol mixture at pH = 9, 8.1, 7.4 and 6.8 using aspectrophotometric method. The data could be well fitted into a model consistent with the formationof a 1:1 complex between the reacting partners. In addition, the results indicated that hemincomplexed more strongly with quinidine than with chloroquine and quinine, and the binding constantswere pH-dependent. Moreover, it was proved that the water-propylene glycol mixture is well suitableto the study of the systems containing hemin and quinoline-based drugs.

Coal catalytic agents (CCS type) have been prepared to improve coal combustion and reduce air pollution. The energy and pollution reductions resulting from the catalysts have been examined with thermal analysis and chromatography. The CCS agents lower the ignition temperature by 3080℃ and improve the coal combustion efficiency by 10%25%. The agents also reduce the release of carbon monoxide, sulfur dioxide, and coal particles to environment. The working mechanisms of the catalysts are discussed in terms of their participation in various physico-chemical processes during combustion.

<正>We are interested in understanding the role electrostatics play in the self-assembly of protein complexes. Specifically,under what conditions and at which strength do the electrostatics affect the protein-protein interactions? To this end,we selected a small globular protein,lysozyme,to study how it unfolds and refolds in the presence of micelles composed of the unstructuredβ-casein proteins by using
