Large quantities of wastewater are generated by the petroleum refining process. Micron-scale emulsion droplets and submicron difficult to remove from oil-refined wastewater, addressing these issues has been a major challenge for researchers. Membrane technology is widely used in water treatment because it very selective effective filtration his research focuses on oil refinery using polysulfone...

This research addresses the extraction and recovery of nickel ions from real electroplating wastewater using SLM process. The process involves three main phase system which are feed, organic and stripping phase. The feed phase containing the nickel electroplating wastewater whereas the organic phase containing the liquid membrane which was immobilized in the membrane support. The liquid membran...

Terms and conditions of current drinking water quality standards, including reducing the maximum arsenic concentration from 50 μgl-1 to 10 μgl-1 and predicted stricter standards in future, reveals the necessity for development of new technologies. This study aimed to prepare and evaluate a new nanocomposite membrane using graphene oxide (GO) thin layer to remove arsenic (v) from water. To fabri...

In this work we investigate how the tactile detection thresholds of air-driven actuators are influenced by design parameters as membrane thickness and diameter, when the finger is in contact with the deformable circular elastic membranes. We report lower thresholds with decreasing membrane thickness and increasing diameters. These results can help in the design of soft actuators for pin-arrays ...

Inkjet printing is a versatile, contactless and accurate material deposition technology. The present work focused on developing innovative strategies for inkjet of Catalyst-Coated Membranes (CCM) by performing Additive Manufacturing (AM) applied to Polymer Electrolyte Membrane Fuel Cells (PEMFC), without resorting intermediate substrates. Three different approaches AM are presented discussed: a...

A mathematical model of amperometric biosensors has been developed. The model is based on non-stationary diffusion equations containing a non-linear term related to Michaelis-Menten kinetics of the enzymatic reaction. Using digital simulation, the influence of the thickness of enzyme membrane on the biosensor response was investigated. The digital simulation of the biosensor operation showed th...

Objective: This first aim of this study was to determine whether there is a relationship between the presence Haller cells and Schneiderian membrane thickness (SMT) by considering factors such as age gender. The second investigate correlation visibility on cone beam computed tomography (CBCT) digital panoramic radiographs. Materials Methods: Seventy-eight edentulous patients were included in st...
