A power plant includes a closed loop, supercritical carbon dioxide system (CLS-COsystem). The CLS-COsystem includes a turbine-generator and a high temperature recuperator (HTR) that is arranged to receive expanded carbon dioxide from the turbine-generator. The HTR includes a plurality of heat exchangers that define respective heat exchange areas. At least two of the heat exchangers have different heat exchange areas.

A solar receiver device includes a metal conduit and a glass container disposed around the metal conduit such that there is a space between the glass container and the conduit. A coating is disposed on the metal conduit and has a composition that includes at least one element from silicon, titanium, aluminum, barium, and samarium.

A nuclear fuel composition includes a nuclear fissile material and a neutron-absorption material that adjoins the nuclear fissile material. The nuclear fuel composition may be used in a nuclear reactor, such as a thermal reactor.

An apparatus for rapidly cooling beer flowing from a keg to a tap to be dispensed includes an insulated ice chest containing an open topped swirl pot in which is nested a cooling coil having an inlet connected to a keg and an outlet connected to a tap on a hollow upright structure fixed to the outside of an ice chest lid. A pump is connected to a stand pipe within the coil directing a flow of ice water under pressure to generally tangentially directed nozzles within the coil creating a swirl flow of ice water over the coil turns and overflowing back into the ice chest interior space holding ice to create a circulation therein maximizing the rate of cooling of the dispensed beer to minimize foaming when dispensed from the tap. A COtank is also held in the ice chest interior space, connected to the keg via fluid lines and simplified hook ups to the keg are located on the lid mounted hollow structure.

A heat transfer tube includes a container, a cavity within the container, and a heat transfer medium located within the cavity. The heat transfer medium consists essentially of a solid-gas suspension of a gas and a substantially homogeneous nanoparticle powder located within the cavity. The cavity is in a partial vacuum state. The nanoparticle powder comprises Ca(OH), LiH, ZrH, or Mg(OH)in a solid state and is capable of substantially freely emitted and reabsorbing the gas as a function of temperature.

A homemade explosives (HME) detection system provides a coded-source, x-ray computed laminography imaging system which detects material composition by the ratio of the transmitted characteristic X-rays within a coded x-ray beam. Motion-free 3-Dimensional geometrical details are obtained through computed laminography imaging techniques.

A neutron-gamma ray tomography system comprises a source, a detector array, and an image processor. The source illuminates an object with a dual neutron-gamma ray beam. The detector array characterizes neutron and gamma ray attenuation in the object. The image processor generates tomography as a function of the neutron and gamma ray attenuation.

Neutron-gamma ray tomography

A variable-ratio neutron-gamma ray source comprises a neutron generator, a shield, a collimator, and an external gamma target. The neutron generator generates neutrons and the shield reduces external radiation exposure. The collimator collimates the neutrons into a neutron beam that traverses the shield. The external gamma target generates a dual neutron-gamma ray beam from the neutron beam, wherein the dual neutron-gamma ray beam has a variable neutron-gamma ratio as a function of a thickness of the external gamma target.

Variable-ratio neutron-gamma ray source

A system for detecting a compound in a sample includes a neutron source, at least one gamma ray detector positioned proximate the sample, and a signal processor. The neutron source directs a neutron beam toward the sample. The gamma ray detector collects gamma rays emitted from the sample and the signal processor determines the compounds in the sample based on the gamma rays collected by the gamma ray detector. The compound is selected from the group consisting of peroxides and superoxides.
