A cobalt(II) ion-selective membrane sensor has been fabricated from a poly vinyl chloride (PVC) matrix membrane containing a new oxime compound (oxime of 1-(2-oxocyclohexyl)-1,2-cyclohexanediol, OXCCD) as a neutral carrier, sodium tetraphenyl borate (NaTPB) as an anionic excluder and o-nitrophenyloctylether (o-NPOE) as a plasticizing solvent mediator. The membrane sensor exhibits a linear poten...

Among the various existing metals, zinc and copper are predominant metals in several effluents from industries such as electroplating, plastics production mining. Technical methods have been applied treatment of containing including chemical removal, adsorption, ion exchange, membrane technologies electrochemistry. However, it is necessary to develop that minimize costs increase quality while r...

Nickel thin films have been electrodeposited without the use of an additional seed layer, on highly doped silicon wafers. These substrates conduct sufficiently well to allow deposition using a peripherical electrical contact on the wafer. Films 2 μm thick have been deposited using a nickel sulfamate bath on both n+and p+-type silicon wafers, where a series of trenches with different widths had ...

This paper reported the pollutant removal performances of a hybrid wetland system for the treatment of aquaculture wastewater. The system consisted of two treatment stages: a subsurface vertical flow (VF) wetland, followed by a horizontal flow (HF). The aquaculture wastewater with the different concentrations such as eutrophy and mesotrophy was treated using hybrid constructed wetland. The expe...

In many regions of the world, urban water systems will need to transition into fundamentally different forms to address current stressors and meet impending challenges-faster innovation will need to be part of these transitions. To assess the innovation deficit in urban water organizations and to identify means for supporting innovation, we surveyed wastewater utility managers in California. Ou...

Electroplating remains an attractive deposition approach for fabricating metal microspherical targets inertial confinement fusion because of its relatively fast rates and ability to produce full-density small grain coatings. Here, we discuss recent advances that allow coating thick (>60 µm) leak-free gold capsules with gradients silver. We present a new apparatus used electroplating hollow (typ...
