Review on Azomethine-Compounds with Their Applications
Abstract: Azomethine derivatives are very important and the initiating compound for most synthetic chemistrycompounds in all their fields. Since R, R1 is an alkyl or aryl group, the first to prepare and isolate itwas the German scientist Hugo Schiff in 1864 from the condensation of the carbonyl group (aldehyde,ketone) with a primary amine compound (aliphatic, aromatic). During the past few decades there hasbeen great interest in Schiff base compounds. The rules …

Experimental Demonstration on Microfluidic-Leakage in SU-8 based Glass Devices for Applications towards the Polymer Microfluidics
Abstract: Classical mechanics and quantum mechanics belong to the first quantisation in physics. Quantummechanics is dependent on quantum theory. Quantum field theory is the second quantisation inphysics. Fluid mechanics is a branch of classical mechanics (non-quantum). Therefore, fluidmechanics is present at the first quantisation in physics. Bulk-fluidics (microfluidics), microfluidicsand nanofluidics are the three levels of fluid mechanics towards miniaturisation. In this experimentalwork, the microfluidic-leakage is prominently demonstrated by fabrication of 12 …
