In this work, we demonstrate for the first time the combination of conventional pressure-driven microfluidics with electrically-programmable digital microfluidics. The use of continuous microfluidics in channels of fixed geometry is widespread and has been used for numerous applications. Digital microfluidics is an emerging area based on programmable electrowetting droplet movement. Merging the...

Critical Infrastructures, such as energy, banking, and transport, are an essential pillar to the well-being of the national and international economy, security and quality of life. These infrastructures are dependent on a spectrum of highly-interconnected information infrastructures for their smooth, reliable and continuous operation. The field of protecting such Critical Information Infrastruc...

The bubble effectiveness in liquid phase cylohexane non-catalytic oxidation process is discussed in this paper. Then the bubble effectiveness and a new proposed kinetic model are used in the mathematical model of the industrial reactor for the cyclohexane non-catalytic oxidation process. Furthermore, simulation and optimization based on this reactor model are carried out. The results of sim...

Nano sulfated titania was tested as solid acid heterogeneous catalyst for the synthesis of 4-(Trifluoromethyl) coumarin and coumarin derivatives under solvent-free condition. Factorial design evidenced a positive effect of reaction temperature, amount of catalyst, and solvents.  This nano-sized sulfated titania has been prepared by a sol-gel hydrothermal process. The prepared sulfated titania s...

The oxidation of o-xylene to phthalic anhydride is one of the important industrial processes based on selective oxidation reactions. For the last 50 years vanadia titania catalysts have been used in this process. The reaction parameters like temperature range of operation, reactor inlet pressure, contact time, etc. slightly changed during this continuous process optimization. However, the funda...

The catalytic transfer hydrogenation (CTH) of glucose to sorbitol has been studied using a wide collection different biomass-derived alcohols and diols as hydrogen donors. Catalytic activity results reflect the feasibility conduct this transformation in presence conventional, commercially available Raney Ni-type sponges catalysts. Sacrificial displayed superior performance donors compared short...
