A product includes a transparent scintillator material, a beta emitter material having an end-point energy of greater than 225 kiloelectron volts (keV), and a photovoltaic portion configured to convert light emitted by the scintillator material to electricity. A thickness the scintillator material is sufficient to protect the photovoltaic portion from significant radiation damage.

Indirect conversion nuclear battery using transparent scintillator material

According to one embodiment, a device includes a first electrode, a second electrode spaced from the first electrode, a well extending between the first electrode and the second electrode, one or more chalcogens in the well, and at least one halogen mixed with the one or more chalcogens in the well. In addition, the chalcogens are selected from the group consisting of sulfur, selenium, tellurium, and polonium.

Liquid semiconductor-halogen based electronics

A product includes a transparent scintillator material, a beta emitter material having an end-point energy of greater than 225 kiloelectron volts (keV), and a photovoltaic portion configured to convert light emitted by the scintillator material to electricity.

According to one embodiment, a product includes an array of three dimensional structures, a cavity region between each of the three dimensional structures, and a first material in contact with at least one surface of each of the three dimensional structures. In addition, each of the three dimensional structures includes a semiconductor material, where at least one dimension of each of the three dimensional structures is in a range of about 0.5 microns to about 10 microns. Moreover, the first material is configured to provide high energy particle and/or ray emissions.

Radiation tolerant microstructured three dimensional semiconductor structure

A black powder firearm (10) is easily disassembled and has interchangeable barrels (12) . Barrels (12) attach to a receiver (24) at a bore (86) in the receiver (24). A lug (50) attaches to the barrel (12) and bolts to the receiver (24) through a hollow lug bolt (46). A bore (98) in the lug bolt (46) holds a ramrod (20) and allows the ramrod (20) to extend into the receiver (24). A breech plug (54) screws into a breech end (16) of the barrel (12). A nipple (58) of the breech plug (54) extends through a hole (88) to engage a hammer (30). A base section (56) of the breech plug (54) abuts a steel portion of the receiver (24). A trigger mechanism (28) has a linear, coil compression hammer spring (102) that is pivotally anchored to a trigger housing (62). This anchor point is displaced from a pivot point for the hammer (30). An anti-blow-back lever (124) engages the hammer (30) when the hammer is in its fired position and a trigger (32) is pulled. The entire trigger mechanism (28) is mounted in the trigger housing 62 so that the entire trigger mechanism (28) may be removed and cleaned as a unit.
