摘要： The high water recovery hybrid membrane system for desalination and brine concentration combines nanofiltration, reverse osmosis and forward osmosis to produce pure water from seawater. The reject side of a nanofiltration unit receives a stream of seawater and outputs a brine stream. A permeate side of the nanofiltration unit outputs a permeate stream. A feed side of a reverse osmosis desalination unit receives a first portion of the permeate stream and outputs a reject stream. A permeate side of the reverse osmosis desalination unit outputs pure water. A draw side of at least one forward osmosis desalination unit receives the reject stream and outputs concentrated saline solution. A feed side of the at least one forward osmosis desalination unit receives a second portion of the permeate stream and outputs a dilute saline stream, which mixes with the first portion of the permeate stream fed to the reverse osmosis desalination unit.

摘要： The apparatus for measuring performance of a suspension for cooling a computer processing unit is a measurement and testing tool allowing for the fabrication of new suspensions, and measuring and testing their short-term and long-term thermal performance in real time on any liquid-cooled computer processing unit. The suspension is prepared in a sample receiving reservoir and pumped across the unit, and then input to an air-cooled heat exchanger for recirculation back to the sample receiving reservoir. Temperatures of the working fluid are measured between the sample receiving reservoir and the computer processing unit, between the unit and the heat exchanger, and after output from the heat exchanger. Pressure differentials of the working fluid is measured across the computer processing unit and across the heat exchanger.

摘要： The device and method for measuring the effect of soiling on a photovoltaic device includes a device in which a photovoltaic device (reference solar cell, solar cells, PV module, etc.) may be shifted between partially and fully enclosed compartments in quick succession for measurements of the same device (1) when directly exposed to illumination or solar radiation; (2) when placed under a glass or transparent cover maintained cleared or cleaned of soil; and (3) when placed under glass or transparent cover left exposed to natural outdoor soiling, or attenuated using simulated soil that is not periodically cleaned. The measurements may be of short circuit current (Isc), maximum power (Pmax), or other electrical parameter conventionally used to evaluate performance of the photovoltaic device. A soiling ratio calculated as: SR Pmax = 1 - P max 2 - P max 3 P max 1 or calculated as: SR Isc = 1 - I sc 2 - I sc 3 I sc 1 may be used to compare or monitor performance of the photovoltaic device between measurement cycles.

摘要： The nanocomposite system for hydrogen storage is a composite of MgH2 powder with ZrNi5 powder and a combination of Nb2O5, TiC and VC. Preferably, the MgH2 is in nanocrystalline form and the ZrNi5 is significantly in a Friauf-Laves phase. The nanocomposite system is formed by combining the MgH2 powder with the ZrNi5, Nb2O5, TiC and VC, preferably in amounts of 4 wt. % ZrNi5+1 wt. % Nb2O5+0.5 wt. % TiC+0.5 wt. % VC, to form a mixture, and then performing reactive ball milling on the mixture. Preferably, the reactive ball milling is performed for a period of 50 hours.

摘要： The desalination system with mineral recovery is a system for desalinating water using spray drying, which allows for both the production of purified water and the recovery of mineral salts. The desalination system with mineral recovery is a two-stage system for zero-liquid discharge (ZLD) desalination of feed water. The feed water may be, for example, seawater, reverse osmosis (RO) brine (i.e., the waste brine from a RO process), nano-filtration (NF) reject, multistage flash (MSF) brine, or the like. The first stage receives the feed water and uses a spray drying process to produce concentrated brine and a first volume of purified water. The concentrated brine is fed to the second stage, which also uses a spray drying process to produce a second volume of purified water and a volume of recovered mineral salts.

摘要： A system for measuring glass transition temperature of a polymer can include a cell having a closed bottom and a peripheral wall extending from the bottom, a sample holder having a first supporting pin and a second supporting pin spaced apart from the first supporting pin, a loading probe in the cell for selectively contacting a polymer sample disposed on the sample holder, a temperature probe in the cell, a heater in the cell, a temperature sensor, a source of pressure, a source of gas in communication with the cell, and a data acquisition system operably connected to the loading probe, the temperature probe and the source of pressure. The first and second supporting pins and the loading probe in the cell provide a three-point flexural bending assembly for measuring bending of the polymer sample under varied conditions of temperature and pressure in the presence of a gas.

摘要： 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.

摘要： The system for processing waste includes both a fixed bed reactor and a fluidized bed reactor. The fixed bed reactor receives a first waste material and produces a first set of reaction products. The fluidized bed reactor is adapted for receiving a second waste material and producing a second set of reaction products. The first and second sets of reaction products may be selectively and adjustably mixed to produce a mixed set of reaction products. At least one cyclone separator receives the reaction products and separates and collects solids (waxes) from the product stream. At least one condenser receives the product stream and removes a condensable liquids from the product stream. The condensable liquids are collected, and a gas-liquid separator removes any remaining liquid from the gas stream. The remaining gas is then output as gaseous product.

摘要： A method for synthesizing thin film stainless steel coating can include using an e-beam PVD technique for depositing elements of stainless steel, i.e., Fe, Cr, Ni, Mo, and Mn, on a target surface, e.g., a surface of metallic origin. The method can include thermal evaporation of a source stainless steel material at a given percentage of electron beam power and a given vacuum pressure to provide a stainless steel coating layer on the target surface. The stainless steel coating layer can have a uniform thickness of about 150 nm, for example. The method can provide uniform stainless steel elemental distribution on the target surface. The stainless steel of the coating layer on the target surface can be of a grade that is different from the source stainless steel.
