Abstract: New adhesives and methods for preparing them are disclosed that include polylactic acid irradiated with gamma radiation, such as by a Co60 source. Irradiation times are used that improve the characteristics of the adhesive materials. Generally, the dose of radiation is from about 5 kGy to about 200 kGy of gamma irradiation. The adhesives generally have melting temperatures in the range of at least about 140 to about 148° C. such that they can be conveniently used in conventional glue guns and other glue equipment. The disclosed adhesives can provide bond strengths in the range of about 1,600 psi or more to about 2,500 psi or more. The disclosed adhesives can include a crosslinking agents. They can be used to join a wide range of substrates including wood, metal, plastic, ceramic, glass or combinations of substrates. They can be conveniently prepared by heating a polylactic acid (polylactic acid) preparation and mixing the molten polylactic acid with one or more crosslinkers when present.

Abstract: A method for generating cavitation resistance in a liquid, a portion of which can be in contact with a surface is disclosed. The disclosed method can be carried out by pressure-treating the liquid, the liquid portion in contact with the surface, and/or the surface for a sufficient time to develop resistance to cavitation. The disclosed method can be carried out when the surface is made of a material having a surface roughness that is greater than the rc of the liquid. Suitable surfaces include borosilicate glass, drawn glass, copper, lead, steel, cast iron, metal alloys and concrete. The surfaces can be ship and boat propeller surfaces, the interior of fuel lines and fuel storage containers or any other surface where cavitation can occur.

Abstract: A system to detect ionizing particles includes an enclosure which holds a fluid in a tensioned metastable state. The interaction of a particle with the liquid creates a respective vapor pocket that can be seen and recorded, and also results in a shock wave that can be heard and recorded. The level of tension metastability in combination with agents, such as Be and B atoms, and surfactants that minimize evaporation losses is associated with a particular type of particle.

Abstract: A nuclear fusion reactor including a structure for placing at least a portion of a liquid into a tension state, the tension state being below a cavitation threshold of the liquid. The tension state imparts stored energy into the liquid portion. A cavitation initiation source provides energy to the liquid portion sufficient to nucleate at least one bubble having a bubble radius greater than a critical bubble radius of the liquid. A structure for imploding the bubbles produces imploded cavities. The temperature generated by the implosion process can be sufficient to induce a nuclear fusion reaction involving the liquid. A method of providing nuclear fusion tensions a liquid, cavitates the tensioned to form at least one bubble, then implodes the bubble, wherein a resulting temperature is generated that is sufficient to induce a nuclear fusion reaction involving the liquid.

A structure for analyzing gamma ray data is communicably connected to the gamma ray detector, the structure for analyzing gamma ray data adapted. The identity and concentration of contaminants in a bulk material can also be determined. By scanning the neutron beam, discrete locations within the bulk material having contaminants can be identified.
