We investigated the self-assembly of cyclodextrin (CD) molecules at the tetradecane–aqueous solution interface through formation of inclusion complexes (ICs). We studied the surface activity of CDs at both the air–water and the oil–water interface. Although a-CD and b-CD are not surface active at the air–water interface, they form pseudo-surfactants as inclusion complexes with linear oil molecu...

To reduce the size of exit burrs induced by broaching, it is possible to use a low value martyred part clamped functional one on tool side. Thence, this research work deals with an in-situ analysis burr formation at bi-specimens interface in orthogonal cutting configuration. New mechanisms formed Inconel 718 and cast iron specimens are identified. In addition, post-machining study carried out q...

A simple model of the formation of Au0.1Ni0.1Sn0.8 in Pb-Sn solder/Ni interconnects is examined by numerical simulation. Previous experimental observation has shown that after reflow the interface consists of the Ni3Sn4 alloy between Pb-Sn solder and Ni, with Au distributed through the PbSn solder ball. Au0.1Ni0.1Sn0.8 was observed to form at the Pb-Sn solder/Ni3Sn4 interface during annealing a...

In this study, polyphenylsulfone (PPSU) hollow fiber membrane was fabricated via a wet spinning method with the addition of ethylene glycol (EG) in the range of 0-10 wt% as the additive. The EG was added to improve the membrane pore formation and interconnectivity for better membrane contactor performance in extracting and removing the free fatty acid (FFA) from crude palm oil (CPO). Four diffe...
