Background & Aims of the Study: Azo dyes utilized in industrial processes, such as the textile manufacturing, lead to the creation of huge amounts of colored wastewaters that contain non-organic and organic constituents. Therefore, it is necessary to search for remedies in this regard. This study investigated the degradation and mineralization of Acid red 14 (AR14), which is a mono Azo dye gene...

In this work, a method is presented for controlling on-chip droplet dispensing by electro-wetting actuation in conjunction with capacitance feedback. The method exploits the built-in capacitance of an electro-wetting device to meter the droplet volume and control the dispensing process. A self-contained system is built to provide continuous-flow loading, capacitance measurement, and electro-wet...

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

We have developed a process for the three-dimensional (3D) machining of p-type silicon on a microand nano-scale using high-energy ion beam irradiation with one or more energies and fluences, followed by electrochemical anodization in hydrofluoric acid. We present a study of the dependence of our fabricated structures on irradiating ion energies, fluences, geometries and wafer resistivity. All t...

An automated fraction collection interface has been developed for coupling capillary electrophoresis (CE) with matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS). This fraction collection approach is based on electromigration and diffusion and does not rely on the presence of a liquid junction, sheath-liquid, electro-osmotic flow, or a superimposed hydrodynamic flow. Neutr...
