Abstract:

Soy protein isolate (SPI) were obtained through ultrafiltration using 10 kDa hollow fibre cartridge, 117.21 kPa trans-membrane pressure and 3.5 volume concentration ratio. SPI prepared by ultrafiltration possessed highest protein content (88±0.3 %) and 91.09±0.84 % nitrogen solubility index (NSI) as compared to 84±0.5 % protein content and 19.29±0.74 % NSI for acid precipitated and 85±0.5 % protein contentfor commercially availableSPI. Ultra filtered SPI also possessed highest value of emulsion stability (ES) of 51.96±1.42 %, whereas commercially available SPI exhibited the least value of 48.3

Abstract:

The purity evaluation of deionized (DI) water is highly desirable for VLSI or ULSI industry, as the traditional "reverse osmosis filter" cannot always meet the requirement towards the DI water. The filtered DI water may still contain many contaminations which are not up to the standard for the wet cleaning of wafer surface. A novel method is presented by analyzing the residues of a water droplet after the low-temperature evaporation. The contamination contained in the water will remain during the gasification. By analyzing the residual contamination's morphology, the purity of the DI water can

Abstract:

Lake water from a Shanghai theme park faces restrictive phosphorus discharge limits (≤0.02 mg/L) that are technically challenging. Laboratory bench top and pilot plant testing were conducted. The results show that a coagulation–ultrafiltration (UF) hybrid process is able to reliably achieve the objective, while a coagulation–sand filter process cannot meet the requirement. Therefore, mature technologies such as Veolia Actiflo® and GE Zeeweed® are preferred for full-scale design. In addition, alum performs better than poly alum chloride on phosphorus removal.

Abstract:

Sample pretreatment is one of the most important steps in guaranteeing the success of a chromatographic analysis. The selected methodology must ensure simultaneously that a sample is “clean” enough for analysis and that the target analytes are not removed in the process.

Abstract:

Microcontamination control is a key parameter for enhancing yield in terms of density of voids within the interface of a bonded wafer. One important cause of void density is time-dependent haze (TDH) or surface-particulate defect density. TDH on silicon surfaces is generated by the interaction of organic volatiles with moisture on the silicon surfaces. Sub-micrometer particle defect density, or haze level, is mainly affected by contamination arising from five factors: people, process, equipment, environment, and processing chemicals and gases. Direct wafer bonding (DWB) is a three-step sequenc

It is a well-established fact that 14C dates from lake sediments are usually too old because of contamination with allochthonous material and/or due to discrete reservoir effects. The latter can occur in soft water lakes and may be examined by the 14C measurement of aqueous plants or the carbon dissolved and suspended in the water column.Some plants assimilate CO2 from the sediment. Their 14C activity is then dependent on the sediment accumulation rate and nutrients stored in the root system may also contribute misleading results.

Abstract:

An experimental study on drainage of different composite filter material in Wenzhou ultra-soft soils was carried out, to investigate the effects of anti-clogging for these composite material. A new instrument was designed to simulate draining process of the ultra-soft soils under vacuum loadings. Based on the experimental results in the form of pump quantity of water, the average settlement of the sludge, the pumping rate and the water content, a comparison was made among six composite filter material (e.g., PVA-1, PVA-2, SAP, superfine fiber, coral cashmere fiber and bamboo fiber) and a tradi

Abstract:

An ultra- thin Ti film with a thickness of less than 30 nm was deposited on the surface of a silicon wafer by the filtered arc deposition system. A novel technique was adopted to create a height step between the coated area and non-coated area (silicon wafer) during deposition. The surface morphology and thickness of the film was detected by atomic force microscopy (AFM). The AFM results showed that the deposited film formed a smooth structure on the silicon wafer and the height step between the coating and silicon wafer was clear enough to give the thickness of the deposited film.

In previous studies [1,2] we showed that treatment of mice with Antimonium crudum (Ant-c) 30cH was able to significantly reduce monocyte migration to the infection site after injection of Leishmania (L) amazonensis into the subcutaneous tissue, resulting in clinical improvement. Follow up was performed with an in vitro model, which showed that treatment of co-cultures of RAW 264.7 macrophages and parasites with Ant-c 30cH inhibited two parasite-induced CCL2 peaks 48 and 120 hours after infection together with early inhibition of lysosome activity. These findings explained the results previousl

To mitigate the damage of oil spills, a filter modified with a hydrophilic and oleophobic coating is proposed for affordable and efficient oil separation and recovery from water. The sol–gel method was chosen to produce a colloidal suspension of titanium dioxide particles for its ease of production and its versatility in application for many different substrates, including paper and cloth fabric. After immersing the substrates into a titanium-containing solution, three techniques were applied to increase the production of titanium dioxide—microwave-assisted, refrigeration, and ultra-sonication

Therefore, the introduction into the practice of designing water treatment methods that ensure the use of compact, high-performance, automatically controlled structures acquires national economic importance.

Abstract:

Traditional water-repellent filter media for water separation in diesel fail to meet requirements due to the high content of surfactants in low sulfur diesel and ULSD (ultra low sulfur diesel). To improve the water separation performance of filter media, a novel dual-layer filter medium was prepared by hydrophilic fibers (glass microfibers) and hydrophobic fibers (kapok fibers and bi-component PET fibers). The results showed that the separation efficiency of a filter medium (sample #2) with the upstream layer containing 20 wt% kapok fibers was 89.5%, which was higher than that of filter sample

To mitigate the environmental effects of oil spills, a novel hydrophilic–oleophobic mixed-coated filter was developed for efficient oil–water separation and surface oil recovery. The coating consisted of titanium dioxide nanoparticles (TiO2) and ultra-fine carbon black powder, deposited onto a 304 stainless-steel mesh substrate via spray deposition, followed by high-temperature sintering. This process induced a phase transition in TiO2 from anatase to rutile, and formed a TiC khamrabaevite.
