Abstract: Coating-less nonplanar ring oscillator lasers are disclosed. Such lasers may eliminate the need for thin-film optical coatings from a laser cavity, solving the problem of optical damage to the coatings, and thus, providing a longer useful lifetime for the laser for space or terrestrial applications. Such lasers may be compact, ultra-stable, and highly reliable, enabling a low phase noise, single frequency laser in a compact package. Such lasers may be used in CW and/or in pulse mode.

Abstract: Disclosed herein are methods of forming substantially crystalline, dense silicon carbide fibers from infusible polysilazane fibers by utilizing a single stage pyrolysis. The pyrolysis is performed using a continuous process in a single furnace with a constant atmospheric condition. Also disclosed are substantially crystalline, dense silicon carbide fibers formed by these methods.

Abstract: In a process and apparatus for treating produced water, the produced water flows through a series of treatment units. A portion of the produced water may by-pass one or more of the treatment units but the by-pass portion may be such that the treated water is still acceptable, for example for discharge or reuse. Concentrations of oil and grease, organic carbon, silica, pH or related parameters in the produced water may be monitored and used to control the process or apparatus. Control of the process may involve one or more of altering a by-pass portion, altering the addition of chemicals, and altering the operation of a unit process. The process may be controlled to respond to upset conditions, or such that the concentration of one or more limiting contaminants is near, but not over, a specified maximum for re-use or discharge.

Abstract: Systems and methods for removing organic contaminants from water may be used, for example, to treat produced water from a steam assisted heavy oil recovery operation. The treated produced water may be re-used to create steam. Alternatively, the produced water may be a blowdown stream treated to facilitate further treatment in a thermal crystallizer. The treatments may include pH adjustment or separating de-solubilized organics or both. Other treatments may include one or more of oxidation, sorption and biological treatments. The treatments may be used alone or in various combinations. One exemplary combination includes reducing the pH of produced water, separating de-solubilized organics from the produced water, and oxidizing the produced water or contacting the produced water with activated carbon.

Abstract: Processes for fabricating ceramic membranes include providing a porous substrate having at least one inner channel extending therethrough and having surfaces defined by porous walls, depositing a coating slurry on surfaces of the inner channel(s), and sintering. Sintering temperatures for the processes range from about 400° C. to 800° C. Coating slurries for use in the processes include a boehmite sol and a colloidal suspension of porous alumina particles.

Abstract: A user device transmits a location update message, indicating a location of the user device, to a network server. Responsive to the location update message, the user device receives from the network server a list of radio frequency beacons transmitted by resource devices and associated service identifiers for services available from the resource devices. A radio frequency beacon received from a resource device is identified as being in the list. A message is sent to the resource device requesting access to a service identified by a service identifier in the list associated with the radio frequency beacon and providing credentials for a user of the user device in the message.

Abstract: A method for ammonia synthesis using a water-gas shift membrane reactor (WGSMR) is presented. The method includes carrying out a water-gas shift reaction in the WGSMR to form a first product stream and a carbon dioxide (CO2) stream, wherein the first product stream includes nitrogen (N2) and hydrogen (H2), and a molar ratio of H2 to N2 in the first product stream is about 3. The method further includes separating at least a portion of the residual CO2 in the first product stream in a CO2 separation unit to form a second product stream, and separating at least a portion of the residual CO2 and carbon monoxide (CO) in the second product stream in a methanator unit to form a third product stream. The method further includes generating an ammonia stream from the third product stream in an ammonia synthesis unit. A system for ammonia synthesis is also presented.

Abstract: A hybrid multichannel porous structure for processing between two fluid streams of different compositions includes a housing and one or more structures disposed within the cavity of the housing in a shell and tube configuration. Each structure includes a body made of a porous, inorganic material and a plurality of channels for processing an optional sweep stream. Each channel is coated with a membrane layer. A feed stream introduced into the housing is in direct contact with the structures such that a gas selectively permeates through the body and into the channels. The gas combines with the sweep stream to form a permeate that exits from each channel. The remaining feed stream forms a retentate that exits from the housing. The feed stream may consist of syngas containing hydrogen gas and the sweep stream may contain nitrogen gas. A power plant that incorporates the hybrid structure is disclosed.
