Formation of microspheres from simple molecules under simulated primitive earth conditions; ultrasound and light radiation

  • S. Valladas-Dubois

We have synthesized microspheres from aqueous solutions of simple molecules submitted to sonolysis at 20 kHz and 800 kHz in an argon atmosphere. Photochemical reaction under room light or UV-irradiation yielded the same microstructures, whose formation has been studied with optical and electronic microscopes.
