1. High-Pressure Microfluidics
Sammanfattning : In this thesis, some fundamentals and possible applications of high-pressure microfluidics have been explored. Furthermore, handling fluids at high pressures has been addressed, specifically by creating and characterizing strong microvalves and pumps.A variety of microstructuring techniques was used to realize these microfluidic devices, e.g. LÄS MER
2. High pressure vulcanization : crosslinking of diene rubbers without vulcanization agents
Sammanfattning : High pressure vulcanization (HPV) is defined in this thesisas crosslinking of rubber materialsat elevated pressure andtemperature, without the use of any vulcanization agents. Thisis atotally new vulcanization technique, not used in theindustry today. LÄS MER
3. Miniaturized fluid system for high-pressure analytics
Sammanfattning : High-pressure chemistry can be used to determine the contents of blood or water samples and to discover new chemistries. However, working with chemistry at pressures of many tens, or even hundreds, of bars often requires expensive and stationary equipment, such as autoclaves or chromatographic systems like high-performance liquid chromatography (HPLC).

4. Synthesis and Tuning of Multifunctional Materials at High Pressure
Sammanfattning : At the present stage, human society is developing at an unprecedented speed, facing an emergence of highly pressing challenges, e.g., information explosion, energy production problems, environmental pollution, climate problems. Functional materials with tailored properties are considered as holding a key to solving these problems. LÄS MER
5. Bonding veneers using only heat and pressure : focus on bending and shear strength
Sammanfattning : A compact laminated board can be obtained by pressing layers of veneers with no other material or substance placed between them. The process does not require the use of steam pretreatment, surface activation methods, a gastight press, friction or adhesives. It strictly involves the heat and the pressure induced by the press in the veneers. LÄS MER
