  • Method for plastic deformation of polymers by electromagnetic radiation
    Patent number: 7901612
    Abstract: According to the invention, a method for the plastic deformation of a polymer is provided, which is characterized in that the polymer is treated with electromagnetic radiation having a wavelength in the range from 0.8 to 100 ?m with simultaneous action of pressure and shearing and thermal energy. By means of the method according to the invention, it is also possible to plastically deform polymers which have to date not been accessible to plastic deformation, such as chitin and in particular cellulose.

  • Method for protecting objects from destruction by laser beams using solid or gaseous protective elements
    Patent number: 4855605
    Abstract: Solid protective elements such as cesium, thallium or luletium are dispersed in or layered on an object so that when a high energy laser beam strikes the object a highly ionized plasma is provided that absorbs or reflects the laser beam. Alternately, the object to be protected is surrounded with a gaseous protective element such as krypton or xenon.
