Overview of Reverse Osmosis for Chemical Engineers Part 1, Fundamentals of Membrane Mass Transfer

Reverse osmosis (RO). has become a standard unit operation in Chemical Engineering. This separation process can be used for a wide variety of applications including: desalination of sea water, treatment of industrial wastes, concentration of food products, and recovery of value materials from solution mixtures. In order to best utilize RO it is necessary to have a fundamental understanding of t...

Glucose-Sensitive Holographic (Bio)Sensors: Fundamentals and Applications

Nowadays sensors and especially biosensors play an important role in medical diagnosis and detection of food and environment contaminations. Biosensors’ facilities have been improved significantly by using technologies such as surface plasmon resonance, microfluidics, laser, and electrochemistry. These technologies are now available on chips in micro- and nano-scale and are capable of mea...

Cytotoxic Effect of Some 1, 4-Dihydropyridine Derivatives Containing Nitroimidazole Moiety

The 1,4-dihydropyridine (DHP) derivatives are a known class of calcium channel blockers. Some derivatives of DHP showed significant cytotoxicity. It was shown that this effect may not be the result of interaction with Ca2+ channels. In this study, we performed an investigation about the intrinsic cytotoxicity of some derivatives of DHP containing nitroimidazole moiety on their C4 position on fo...
