We studied flow rate, electrolytes effects, titanium dioxide separation and reuse and sunlight application on photocatalysis in a tubular photoreactor integrated with the titanium dioxide separation/reuse. The circulative flow treatment was preferred over the single pass treatment. Phenol and TOC removals in tap and deionized waters were a maximum at the circulative flow rate of 600 ml min and ...

In order to synthesize Bi2Se3 nanopowders by a solvothermal synthesis method, ethylenediamine, dimethylformamide, acetone, absolute ethanol, and deionized water were respectively used as a solvent, using BiCl3 and elemental Se powders as starting materials and KBH4 as a reductant at 180 C for different times. X-ray diffraction was used for examining the phase composition of the products. The re...

Anion exchange membrane water electrolyzers (AEMELs) have recently received significant attention due to their potential advantages over proton (PEMELs). However, some AEMELs feed an aqueous salt solution the cell where PEMELs typically deionized (DI) water. DI is preferred keep system and maintenance costs low. Because of this, many AEMEL researchers report performance both in (typically KOH) ...

The spreading of small hydrocarbon droplets (pentane, heptane, dodecane, hexadecane) on the water surface was recorded using a Kodak high-speed video system with a speed of 1000 frames per second. The results showed that the spreading of low-viscosity hydrocarbons on a water surface is a very spontaneous process and is usually completed in 10-15 ms for drops with a diameter of 3-4 mm. It was fo...

This study was conducted to evaluate the effect of aerosol generation, methods of sampling, storage conditions, and relative humidity on the culturability of the mycobacteriophage D29. The lytic phage D29 can kill Mycobacterium tuberculosis, and the phage aerosol can be treated as a potential tool for tuberculosis treatment. The culturability of D29 was tested using a test chamber designed for ...

A point-of-use 0.2-microm filter was evaluated for elimination of nontuberculosis mycobacteria in laboratory water to reduce false-positive acid-fast bacillus staining results. Use of the point-of-use filter can significantly reduce the false-positive rate to 1.2% compared to samples treated with tap water (10.7%) and deionized water (8.7%).

The neutral ultraviolet and visible (UV/vis) spectra were measured in a 2:1 2-methoxyethanol/water (v/v) solvent and according to standard literature procedures. The UV/vis data was acquired using a Lambda 900 UV spectrometer. Briefly, the absorption spectra were recorded from 200 to 800 nm using a pathlength of 10 mm, a bandwidth of 1.0 nm and a scan speed of 250 nm/min. Only matched cuvettes ...

Novel complexation hydrogel nanospheres of poly(methacrylic acid-grafted-poly(ethylene glycol)) (P(MAA-gEG)) were prepared by dispersion polymerization to be used for protein delivery applications. Polymerization was conducted in solvents such as deionized water, ethanol/water, sodium hydroxide, hydrochloric acid, and acetic acid solutions. When polymerizing in deionized water we produced nanos...

As one of the most promising processing methods, microelectrical discharge machining (micro-EDM) process is widely used in industrial production; however, material removal mechanism micro-EDM deionized water has not been clarified due to scale effect. In this paper, influence parameters on crater size was studied by means a single-pulse experiment using resistor–capacitor circuit (RC circuit). ...
