  • Patent number: 11052599
    Abstract: Stereolithography using solid thermoplastic photopolymer plates/sheets/films provides a new technique to make 3D printed objects. In this new additive manufacturing process, objects are built layer-wise using thermoplastic photopolymers and actinic radiation. The thermoplastic photopolymer compositions consist of a thermoplastic photopolymer layer sandwiched between a transparent flexible base without an anchoring layer and a release film. Un-crosslinked portions of the 3D printed object are removed by heat.
    Type: Grant

    Abstract: Dry stereolithography using solid thermoplastic photopolymer plates/sheets/films provides a new technique to make 3D printed objects. In this new additive manufacturing process, objects are built layer-wise using thermoplastic photopolymers and actinic radiation. The thermoplastic photopolymer compositions consist of a thermoplastic photopolymer layer sandwiched between a transparent flexible base without an anchoring layer and a release film. Uncrosslinked portions of the 3D printed object are removed by heat. Preferred method of radiation exposure is digital light processing (DLP).

  • Patent number: 8720677
    Abstract: Stimuli-responsive highly absorbent superabsorbent polymers (SAPs) are used to harness water to augment water supply and solve water crisis. Rain water, dew or sea water is harnessed in fabric-based sachets or bags partially filled with the polymers. The hydrated polymers are used to store water in warehouses for an extended period of time and the invention may obviate the need to construct controversial huge dams and canals or drill wells. The stored water in superabsorbent polymers is released at the point of use by any stimulus which may be light-induced, electrical, thermal or chemical treatment. SAPs with 2000 g/g of absorbency can yield 99.95% pure water in solid/gel form. An ultra SAP with absorbency of 10,000 g/g of the polymer could hold 10 billion cu·m. of water in one million tonnes of the polymer. This is more than the capacity of a typical large dam over a river.

  • Publication number: 20120071609
    Abstract: A method for harnessing rain and dew water with superabsorbent polymers. Highly absorbent superabsorbent polymers which are stimuli-responsive are used to absorb rain/dew water to augment water supply and solve water crisis. The polymers may be recycled and rehydrated number of times. They may be an additional source for drinking water. The polymers are used for storage of water in warehouses and the invention may obviate the need to construct controversial huge dams and canals or drill wells. The stored water in superabsorbent polymers is released at the point of use by any stimulus which may be mechanical, light-induced, electrical, thermal treatment or chemical treatment. Superabsorbent polymers with absorbing power of at least 1000 times their own weight are preferred. With 2000 g/g of swelling capacity, we can have 99.95% pure water in solid/gel form. In solid form, water can be transported anywhere without leakage.

  • Publication number: 20100072297
    Abstract: A method for controlling hurricanes by raising temperature in the eye and/or in the outflow. Air temperature within the eye and in the outflow of a hurricane is raised by flying scores of jet planes with afterburners in the structure. Small changes in temperature on a large scale bring in large changes in other variables on the smaller scale to change the direction and intensity of the hurricane.
