The combination multi-effect distillation and multi-stage flash evaporation system integrates a multi-stage flash (MSF) evaporation system with a multi-effect distillation (MED) system such that the flashing temperature range of the MSF process is shifted upward on the temperature scale, while the MED distillation process operates in the lower temperature range. The multi-stage flash evaporation system includes a plurality of flash evaporation/condensation stages, such that the multi-stage flash evaporation system receives a volume of seawater or brine from an external source and produces distilled water. The multi-effect distillation system includes a plurality of condensation/evaporation effects, such that the multi-effect distillation system receives concentrated brine from the multi-stage flash desalination system and produces distilled water.

Because of its low density, storage of hydrogen in the gaseous and liquids states possess technical and economic challenges. One practical solution for utilizing hydrogen in vehicles with proton-exchange fuel cells membranes is storing hydrogen in metal hydrides. Magnesium hydride (MgH2) remains the best hydrogen storage material due to its high hydrogen capacity and low cost of production. Due to its high activation energy and poor hydrogen sorption/desorption kinetics at moderate temperatures, the pure form of MgH2 is usually mechanically treated by high-energy ball mills and catalyzed with different types of catalysts. These steps are necessary for destabilizing MgH 2 to enhance its kinetics behaviors. In the present work, we used a small mole fractions (5 wt.%) of metallic glassy of Zr70Ni20Pd10 powders as a new enhancement agent to improve its hydrogenation/dehydrogenation behaviors of MgH2. This short-range ordered material led to lower the decomposition temperature of MgH 2 and its activation energy by about 121 °C and 51 kJ/mol, respectively. Complete hydrogenation/dehydrogenation processes were successfully achieved to charge/discharge about 6 wt.%H2 at 100 °C/200 °C within 1.18 min/3.8 min, respectively. In addition, this new nanocomposite system shows high performance of achieving continuous 100 hydrogen charging/discharging cycles without degradation.

The gelling agent for water shut-off in oil and gas wells is a composition that forms a gel to reduce or eliminate the flow of water in a gas or oil well. The composition is formed by mixing polyvinyl alcohol, a polyvinyl alcohol copolymer, or mixtures thereof with an amino-aldehyde oligomer, such as urea formaldehyde or melamine formaldehyde, with or without a cross-linker. The polymer composition can be used to minimize or completely shut off excess water production with insignificant reduction in hydrocarbon productivity.

The floating breakwater includes various different embodiments, as can have an anchored or moored float. The float is desirably in the geometric form of a generally rectangular solid configuration, but can include other forms. One or more baffles or skirt walls extend from the bottom surface of the float, thereby attenuating subsurface wave action to a greater depth than the bottom of the float. Each of the baffles or skirt walls desirably includes a thin, flat, monolithic plate member for enhancing hydrodynamic resistance. The one or more baffles or skirt walls can be continuous and unbroken, or can have a plurality of apertures therethrough. When three or more baffles or skirt walls are provided they can be evenly spaced, or the spacing therebetween can vary. When two or more baffles or skirt walls are provided they can have equal depths, or their depths can differ from one another.

The process using multiple waste streams to manufacture synthetic lightweight aggregate includes providing a mixture of aggregate wash and at least one of another waste stream, such as waste lube oil or sewage sludge. The mixture is formed into pellets and subjected to various firing stages and temperatures in which the calcination and subsequent bloating occurs. The mixture can also be added to natural clays to form corresponding pellets. The bloating promotes formation of porous cavities, and once cooled, the pellets form lightweight, low density synthetic aggregates suitable for use as building materials, thermal insulators, and the like.

The planchet holder for electrodeposition of materials includes a container cover configured to securely fit over the mouth of a beaker. An elongate suspension post passes through a through-hole in the cover a predetermined distance, and a holder assembly is coupled to the suspension post to be suspended within the beaker at a select height from the bottom of the beaker. A planchet receptacle extends axially from a body of the holder assembly, and a substrate recess is formed at a distal end of the planchet receptacle for selective placement of a planchet. An endcap is secured onto the planchet receptacle to securely capture the planchet, and a port in the endcap exposes one face of the planchet for electrodeposition of a material. The planchet holder holds the planchet stationary within the beaker and exposes only one face for electrodeposition and subsequent analysis, thereby reducing time and costs.

The nanocomposite mixed-matrix membrane is a nanocomposite made from a nanofiller of Halloysite nanotubes or polypropylene-grafted maleic anhydride nano-layered silica dispersed or embedded in a hydrophobic polymer matrix. The Halloysite nanotubes are a 1:1 layered alumino-silicate clay having the chemical formula Al_(2)O_(3)Si_(2)O_(4)4(H_(2)O)) formed into multi-layered hollow cylinders having walls that are formed from alternating layers of alumina and silica. The membrane is formed by extrusion of the nanocomposite with stretching over rollers during the extrusion, followed by annealing, cold stretching at room temperature, and hot stretching. The resulting membrane is macroporous and can be used as a membrane distillation (MD) membrane for seawater and brackish water desalination.

The bore hole tracer injection apparatus is a mechanical device for inserting a tracer agent into a bore hole at a predetermined depth. Outer and inner cylinders have side ports, with the side ports of the cylinders misaligned to prevent fluid escape from the inner cylinder until desired. The bottom of the inner cylinder includes a filler passage. A line passes through the top of the outer cylinder and attaches to a rod across the top of the inner cylinder, above the closed top thereof. The inner cylinder is filled with a tracer agent, and the apparatus is lowered into the bore hole to the desired depth. A weight is then dropped down the line, and jars the outer cylinder down around the inner cylinder when it contacts the top of the outer cylinder. This aligns the side ports of the cylinders to allow escape of the tracer agent therefrom.
