in this study, different methods of separating of the microalgae from the culture medium as one of the most important and expensive steps in achieving commercial production of biodiesel from microalgae was investigated. electro coagulation-flotation (ecf) was preferred among these methods due to its process simplicity and capability to scale up. the effect of three parameters, i.e., initial ph,...
A black mask (BM) is a layer used to improve the display quality by suppressing light leakage. In general, the BM is formed by a photolithography process. In this study, a novel technique for the fabrication of a quasi-black mask (q-BM) is proposed; the q-BM was composed of vertical and hybrid orientation areas, patterned by a separation coating technique using an electro-spray deposition metho...
The polymer stabilized liquid crystal (PSLC) film is a relatively novel electro-optical material, which is generally obtained by dissolving a small amount of a bifunctional photoreactive monomer in a low molecular mass liquid crystal. In this paper, the PSLC films were prepared with photoreactive biphenyl methacrylate monomers by photopolymerization induced phase separation. The effects of liqu...
The electro-spraying process can be regular and periodic, consisting of cyclical phases of initiation (meniscus, drop, and/or jet), pulsation, deformation and separation. This paper presents an experimental study on the repetition frequency of drop and/or jet ejection from the capillary end with various spraying modes during an electro-spraying process of deionized (DI) water. The influence of ...
Environmental protection has become the focus of world-wide research in the gold mining industry and favours the development of environmentaly sound processes, such as the Coal Gold Agglomeration (CGA) process, which is an alternative to existing gold processing methods, such as cyanidation and mercury amalgamation. The CGA process was developed and patented by the British Petroleum (BP) resear...
The 20th edition of the International Symposium on Electro- and Liquid-Phase Separation Techniques (ITP2013) took place on October 6-9, 2013, at Puerto de la Cruz in Tenerife, Canary Islands (Spain). This article reviews the highlights of this new edition of the symposia, also including the different activities that took place as well as the awards presented.
Through the use of ambient pressure X-ray photoelectron spectroscopy (APXPS) and a single-sided solid oxide electrochemical cell (SOC), we have studied the mechanism of electrocatalytic splitting of water (H2O + 2e(-) → H2 + O(2-)) and electro-oxidation of hydrogen (H2 + O(2-) → H2O + 2e(-)) at ∼700 °C in 0.5 Torr of H2/H2O on ceria (CeO2-x) electrodes. The experiments reveal a transient build-...
