Plant air purification enclosure apparatus and method

A plant air purifying enclosure, or “PAPE,” contained within an unconditioned space, either within or outside a building, containing therein a plant air purifier, which is used to purify air using plants and microbes growing therein. The PAPE enclosure itself receives poor indoor quality air from within structure where the PAPE is located or from a structure close by along with thermal energy which keeps the plant air purifier enclosure at a suitable temperature for the plants and air cleaning microbes within the air purifier. Poor air enters the enclosure, is purified by the plants and microbes, and returns in purified form back to the habitable space from which it was taken. This lowers the amount of outside air needed for ventilation purposes and so lessens a building's overall energy consumption while providing efficiently for naturally purified air. Fundamentally, the object of this invention is to specify devices, systems and methods to house/enclose plant purifiers in such a way that they can readily be deployed on a wide scale.

Purification of carbon nanotubes using agarose column and density gradient ultracentrifugation

A method of processing bundles of carbon nanotubes (CNTs). Bundles of CNTs are put into a solution and unbundled using sonication and one or more surfactants that break apart and disperse at least some of the bundles into the solution such that it contains individual semiconducting CNTs, individual metallic CNTs, and remaining CNT bundles. The individual CNTs are separated from each other using agarose bead column separation using sodium dodecyl sulfate as a surfactant. Remaining CNT bundles are then separated out by performing density-gradient ultracentrifugation.

Method and apparatus for sequencing-batch purification of potassium nitrate from solid waste produced by glass-strengthening process

Provided is a method and an apparatus for purifying potassium nitrate from the solid waste produced by a chemical glass-strengthening process. In the method, the solid waste is melted into a liquid waste at first. Potassium nitrate of various purity grades can be obtained by batch processing the liquid waste through stepwise cooling processes of cooling the liquid waste to a first temperature facilitating the potassium nitrate contained in the liquid waste to be crystallized at a first rate and then cooling the liquid waste to a second temperature close to the freezing point of the potassium nitrate at a second rate that is slower than the first rate. The recovered potassium nitrate from the solid waste can be recycled and reused.

Interconnected system and method for the purification and recovery of potash

The present invention provides a kiln for the combustion of agricultural waste. The kiln includes a central cylindrical combustion chamber. The central cylindrical combustion chamber includes a system for the control of combustion air to the combustion chamber. The kiln includes a second concentric cylinder surrounding the central cylindrical combustion chamber. The second concentric cylinder includes a system for the flow of cooling water through the first annulus between the central cylindrical combustion chamber and the second concentric cylinder. The kiln includes a system for the feeding of the agricultural waste into the central combustion chamber. The kiln includes a temperature sensing device to measure and display the temperature within the central combustion chamber during the combustion of the agricultural waste. The kiln includes a system for the recovery of ash from the kiln. In operation, the temperature of combustion is controlled to between 550° C. and 650° C. by a combination of increasing the supply of combustion air when the temperature in the central combustion chamber falls to near 550° C. and the introduction of cooling flowing water when the temperature in the central combustion chamber approaches 600° C.

BLOOD PURIFICATION APPARATUS

A blood purification apparatus capable of achieving a simplified configuration and switching between hemodialysis treatment (HD), hemofiltration treatment (HF), and hemodiafiltration treatment (HDF) as well as selecting from pre-dilution, post-dilution and pre and post-dilution easily and smoothly. The blood purification apparatus includes: a valve means 3 that is capable of closing and opening a dialysate introduction line and a dialysate supply line L3 in any manner, and a control unit 5 that operates the valve means 3 to allow any treatment to be performed selected from hemodialysis treatment in which the dialysate supply line L3 is closed while the dialysate introduction line L1 is opened, hemofiltration treatment in which the dialysate supply line L3 is opened while the dialysate introduction line L1 is closed, and hemodiafiltration treatment in which hemodialysis and hemofiltration are performed concurrently by alternately closing and opening the dialysate introduction line L1 and the dialysate supply line L3.

SYSTEM AND METHOD FOR PURIFICATION OF AN EXHAUST STREAM BY USE OF TWO REDUCTION CATALYSTS

An exhaust treatment system comprising a first oxidation catalyst to oxidise nitrogen and/or carbon compounds in an exhaust stream and a first dosage device downstream of said first oxidation catalyst to supply a first additive. A first reduction catalyst device is arranged downstream of said first dosage device for reduction of nitrogen oxides using said first additive, and for the generation of heat, through at least one exothermal reaction with said exhaust stream. A particulate filter arranged downstream of said first reduction catalyst device to catch soot particles and a second dosage device, arranged downstream of said particulate filter to supply a second additive. A second reduction catalyst device is arranged downstream of said second dosage device for reduction of nitrogen oxides in said exhaust stream, through the use of at least one of said first and said second additive.

Separation of postprandial lipoproteins: improved purification of chylomicrons using an ApoB100 immunoaffinity method [Methods]

Elevated levels of triglyceride-rich lipoproteins (TRLs), both fasting and postprandial, are associated with increased risk for atherosclerosis. However, guidelines for treatment are defined solely by fasting lipid levels, even though postprandial lipids may be more informative. In the postprandial state, circulating lipids consist of dietary fat transported from the intestine in chylomicrons (CMs; containing ApoB48) and fat transported from the liver in VLDL (containing ApoB100). Research into the roles of endogenous versus dietary fat has been hindered because of the difficulty in separating these particles by ultracentrifugation. CM fractions have considerable contamination from VLDL (purity, 10%). To separate CMs from VLDL, we produced polyclonal antibodies against ApoB100 and generated immunoaffinity columns. TRLs isolated by ultracentrifugation of plasma were applied to these columns, and highly purified CMs were collected (purity, 90–94%). Overall eight healthy unmedicated adult volunteers (BMI, 27.2 ± 1.4 kg/m2; fasting triacylglycerol, 102.6 ± 19.5 mg/dl) participated in a feeding study, which contained an oral stable-isotope tracer (1-13C acetate). We then used this technique on plasma samples freshly collected during an 8 h human feeding study from a subset of four subjects. We analyzed fractionated lipoproteins by Western blot, isolated and derivatized triacylglycerols, and calculated fractional de novo lipogenesis. The results demonstrated effective separation of postprandial lipoproteins and substantially improved purity compared with ultracentrifugation protocols, using the immunoaffinity method. This method can be used to better delineate the role of dietary sugar and fat on postprandial lipids in cardiovascular risk and explore the potential role of CM remnants in atherosclerosis.
