Abstract: An amorphous polylactic acid polymer having a weight average molecular weight in the range of about 35,000 to 180,000 is described. The polylactic acid polymer composition can be hammer milled without cryogenics result in the form of particles wherein 90% of the particles have particle size of about 250 ?m or less and the material has a glass transition temperature of between about 55° C. to about 58° C. and a relative viscosity of about 1.45 to about 1.95 centipoise. The polymer composition can be used to form an aqueous suspension. The material is ideally suited for use in preparing particleboard. A method is disclosed for preparing such polylactic acid polymers. The method involves obtaining an amorphous polylactic acid polymer having a weight average molecular weight of between about 115,000 to about 180,000. Treating the polylactic acid polymer to reduce the molecular weight to between about 35,000 to 45,000 such that it has a glass transition temperature of between about 55° C. and 58° C.

Abstract: Methods and systems that utilize centrifugally tensioned metastable fluid detector (CTMFD) sensors and an external probing source to detect the presence of fissile and fissionable materials, including but not limited to special nuclear materials (SNMs), in containers. Such a method includes subjecting a container to probing with a fission-inducing radiation species that induces fission in an fissile or fissionable material, detecting fission neutrons emitted from the fissile or fissionable material with CTMFD sensors that each contain a detection fluid in which the fission neutrons induce cavitation in a centrifugally tensioned portion of the detection fluid. A threshold energy neutron analysis mode is then utilized to reject the radiation species and detect a fraction of the fission neutrons that have energies above a predetermined energy threshold determined by centrifugally-induced tension in the centrifugally tensioned portion of the detection fluid within each of the CTMFD sensors.
