1. Ge/high-k Gates for Monolithic 3D Integration
Sammanfattning : Continuous scaling of transistor dimensions has been in the heart of semiconductorindustry for many years. Recently the scaling has been enabled by various performance boosters which resulted in increased processing complexity and cost, forcing the chip manufacturers to look for some alternative solutions.

2. Microstructure and mechanical properties of low-temperature hot isostatic pressed Ti-6Al-4V manufactured by electron beam melting
Sammanfattning : Ti-6Al-4V manufactured by electron beam melting Keywords: Additive manufacturing, high-temperature tensile properties, low cycle fatigue, neutron diffraction, fatigue crack growth ISBN: 978-91-89325-27-2 (Printed) 978-91-89325-26-5 (Electronic) Ti-6Al-4V is the most widely used α+β titanium alloy in aerospace engine applications due to its high specific strength. Typically, the alloy is manufactured as castings or forgings and then machined to final geometry. LÄS MER
3. RF-microwave sensor development for cell and human in vitro and ex vivo monitoring
Sammanfattning : In this research new RF/microwave-based sensor solutions were developed for the monitoring of biological cells and human beings to obtain a better understanding of their activity or state in a quick, cheap, easy and continuous way. The effect of different substances on cell behaviour can be monitored by measuring the electrical environment where changes are observed as cells react to a stimulus. LÄS MER
4. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation
Sammanfattning : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. LÄS MER
5. Acclimation of plants to combinations of abiotic factors : connecting the lab to the field
Sammanfattning : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. LÄS MER
