Popular Abstract in Swedish Nanoteknik och nanotrådar omnämns ofta media idag, men vad är egentligen en nanotråd, och vad kan den användas till? Dagens datorer, lysdioder och solceller är till stor del beroende av halvledare. En halvledare är ett kristallint material där man enkelt kan ändra ledningsförmågan. Man kan dels bestämma ledningsförmågan när materialet tillverkas genom att tillföra ytterThis thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. The first part of the thesis describes the development of Hall effect measurements, an entirely new characterization tool for nanowires. It is shown that Hall effect me

Throughout history packages are used to contain, store and transport goods and products. In early days it was a matter of gathering and storing locally, whereas in today’s global enterprises packaging is an important issue in the operational management in networks of functions and/or divisions, often separated geographically around the world. Packaging has become a part of the process of efficient

A new mechanical scanner design for a high-speed atomic force microscope (AFM) is presented and discussed in terms of modeling and control. The positioning range of this scanner is 13 mum in the X- and Y-directions and 4.3 mum in the vertical direction. The lowest resonance frequency of this scanner is above 22 kHz. This paper is focused on the vertical direction of the scanner, being the crucial

Popular Abstract in Swedish Vatten är inte bara en oumbärlig resurs varav allt liv är beroende. Det är också en grundläggande ekonomisk resurs för samhällsutvecklingen. Av allt vatten på jorden är bara 0,34% tillgängligt för människan. Övriga vattenresurser föreligger som saltvatten, is eller djupt liggande grundvatten. Vattenkrisen på jorden är stor och över 780 miljoner människor saknar rimlig tFresh water scarcity, pollution and an uneven distribution have caused an increasingly serious global water crisis. One of the most widely adopted response strategies is the exploitation and use of non-conventional water sources. Water reuse and desalination were in focus in the study which was aimed to develop the strategies to promote the sustainable and safe use of reclaimed water and desalinat

The focus of the current paper: the patient perspective and the patients’ experienced values versus costs for medication. These values (in plural) and also the costs (in all its meanings) may differ considerably from those that could be gained from ordin
