1. Paraffin Actuators in Microfluidic Systems
Sammanfattning : There is a need for reliable valves and pumps in microfluidics. A good microactuator is the key for low cost and high performance of these components.Paraffin wax is a promising material to be used as actuator material as is can produce large forces and large strokes. LÄS MER
2. Microactuators for Powerful Pumps
Sammanfattning : When paraffin wax melts it exhibits a large, relatively incompressible volume expansion. This can be used in microactuators for strong and large displacements, a rare combination among actuators. Furthermore, paraffin is inexpensive, inert and environmentally friendly, as well as easily processed and actuated. LÄS MER
3. Integrated Communications and Thermal Management Systems for Microsystem-based Spacecraft : A Multifunctional Microsystem Approach
Sammanfattning : This thesis explores the potential of multifunctional silicon-based microsystems for advanced integrated nanospacecraft (AIN). Especially, multifunctional microsystems with the coexistant functions of communications and thermal management implemented in multilayer silicon stacks are approached with systems study. LÄS MER
4. Studies of Colloidal Stability Using Diffusion NMr and Optical Scanning
