 Title    Temperature Induced S p ectral C h an ges o f Chlorophyll in M ic e lle s and S o lu tio n  
 Abstract    Effects of temperature on the spectral properties o f chlorophyll in solution and in m icelles are reported. After correcting for the volum e expansion coefficient o f the solvent, it is observed that temperature has no detectable effects on the spectral properties o f chlorophyll (between 14 °C to 35 °C). Solutions exam ined include acetone, chloroform and ethyl alcohol. It is concluded that the temperature induced change in refractive index, o f the solvent, has no significant affect on the chlorophyll sp ec­ trum. In micelles containing chlorophyll there are significant temperature induced spectral changes. Heating and cooling results in an irreversible redistribution o f m onom eric and oligomeric forms o f chlorophyll.

 Title    Spontaneous Formation of Giant Phospholipid Vesicles  
 Abstract    The spontaneous formation of giant (diameter > 10 pm) vesicles from a number of phospholi-pids in excess aqueous solution has been studied by light-microscopy. Electrically neutral as well as charged phospholipids swell to form giant vesicles only if the lipids are in the fluid phase. This shows that electrostatic repulsion alone cannot explain the spontaneous formation of giant vesi-cles. The results confirm the suggestion that steric forces between extended membranes play a significant part in this process.
