The Effect of Composition on the Role of Evaporation During Oil Recovery by Combustion
One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. The ... En savoir plus
High Curvature Bending of Ultra-Thin Chips and Chip-on-Foil Assemblies
Ultra-thin chips of less than 20µm become flexible, allowing integration of silicon IC technology with highly flexible electronics. This combination allows for highly intelligent products of unprecedented thinness, flexibility and cost. Examples include sensor systems integrated into ... En savoir plus
Theoretical Study of Phase and Amplitude Characteristics of Microwave Coplanar Delay Line Containing Thin Ferroelectric Layer
