Abstract: A boiler system having a series of boilers. Each boiler includes a shell having an upstream end, a downstream end, and a hollow interior. The boilers also have an oxidizer inlet entering the hollow interior adjacent the upstream end of the shell and a fuel nozzle positioned adjacent the upstream end of the shell for introducing fuel into the hollow interior of the shell. Each boiler includes a flue duct connected to the shell adjacent the downstream end for transporting flue gas from the hollow interior. Oxygen is delivered to the oxidizer inlet of the first boiler in the series. Flue gas from the immediately preceding boiler in the series is delivered through the oxidizer inlet of each boiler subsequent to the first boiler in the series.

Abstract: The present disclosure is generally directed to a burner and boiler/furnace for pressurized oxy-combustion boilers and furnaces. The disclosure includes a design of a burner and boiler for a staged, pressurized oxy-combustion (SPOC) technology process and designs that affect wall heat flux. The disclosure further includes the introduction of wall rings to increase, for example, advection.

Abstract: A layered composite composition having a general chemical formula of Li?-xADx(Mn?-y-?AlyNi?-?Co?-zAEDz)O2, wherein AD is an alkaline dopant for Li, AED is an alkaline earth dopant for Co or Ni, and Al is a dopant for Mn or Ni, and at least two of AD, AED, and Al are present in the composition, and the dopants, if present, are at an amount that does not result in the formation of new phase.

Abstract: A lithium metal oxide positive electrode material useful in making lithium-ion batteries that is produced using spray pyrolysis. The material comprises a plurality of metal oxide secondary particles that comprise metal oxide primary particles, wherein the primary particles have a size that is in the range of about 1 nm to about 10 ?m, and the secondary particles have a size that is in the range of about 10 nm to about 100 ?m and are uniformly mesoporous.

Abstract: A non-oxide powder of which at least about 40% by mass is comprised of a plurality of tightly agglomerated compositions, each of the tightly agglomerated compositions comprising a plurality of primary particles agglomerated together. Suitable materials for the primary particles include metals, intermetallics, ceramics, MMCs, and non-metals. An encapsulation and scavenging process is used to create the agglomerated compositions wherein at least some of the agglomerated compositions are encapsulated in a secondary material such as a salt or a polymer.

Abstract: A method and apparatus for reacting sodium vapor with gaseous chlorides in a flame to produce nanoscale particles of un-oxidized metals, composites and ceramics. The flame is operated under conditions which lead to condensation of a NaCl by-product onto the particles. The condensate encapsulates the particles and aids in controlling desired particle size and preventing undesirable agglomeration among the particles during synthesis. Following synthesis, oxidation of the particles is inhibited by the encapsulation and handling character of the products is greatly enhanced. Electron microscopy has revealed that synthesized products are composed of discrete nanoparticles in a NaCl matrix. The NaCl encapsulate has been effectively removed from the particles by both washing and known sublimation technique at 800.degree. C. under low pressure.

Abstract: An optical device provides a unitary, functional eyewear device that enables the viewer to simultaneously receive both primary (on-axis) and secondary (off-axis) images. The optical device includes a primary lens, of a shape and size to be mounted in a frame and worn as traditional eyewear. This primary lens has some inherent reflectivity, transmitting some portion of the light reaching it, and reflecting the remainder. A secondary image mirror portion is preferably mounted along one edge of the primary lens so as to capture at least some desired portion of the light reflected from the primary lens. This secondary image mirror acts more as a true (opaque) mirror, reflecting some significant portion of the light impinging upon it. By proper alignment of this secondry image mirror adjacent the primary lens, some of the light initially reflected by the primary lens is re-reflected back towards the primary lens, where a portion of such light will be transmitted through the primary lens to the viewer's eye.
