1. 16. Detailed simulation of heterogeneous wireless sensor networks

   Författare :Joakim Eriksson; Thiemo Voigt; Per Gunningberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Sammanfattning : Wireless sensor networks consist of many small nodes. Each node has a small microprocessor, a radio chip, some sensors, and is usually battery powered which limits network lifetime. Applications of wireless sensor networks range from environmental monitoring and health-care to industrial automation and military surveillance. LÄS MER

3. 17. Tethered Lipid Vesicles as Nanoscale Sensor Elements

   Författare :Seyed Tabaei; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aquaglyceroporin; lipid vesicles; total internal reflection fluorescence TIRF microscopy; cell membrane; aquaporin; pore formation; surface plasmon resonance SPR ; phospholipase A2; antiviral peptide; lipid bilayer; biosensing; microfluidics;

   Sammanfattning : The primary aim of this thesis work has been to explore and advance the potential of surface tethered lipid vesicles as a platform for studying in particular the following three biomembrane-related processes: trans-membrane transport, membrane-peptide interactions and the activity of membrane active enzymes. First, a method based on surface plasmon resonance (SPR) spectroscopy was developed for studying passive diffusion processes as well as the membrane-protein mediated transport of small non electrolyte molecules across lipid bilayers.

4. 18. Photopatternable Electrolytes for Conducting Polymer Actuators

   Författare :Yong Zhong; Edwin Jager; Anthony Turner; Jose Gabriel Martinez; Aleksandar Matic; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Electroactive polymers (EAPs) are materials that can change their dimensions or shape in response to electric stimulation. They have attracted considerable interests for their applications as soft, lightweight and silently operating polymer actuators. One significant group of EAPs is conducting polymers. LÄS MER

5. 19. Tailoring Conducting Polymer Interface for Sensing and Biosensing

   Författare :Lingyin Meng; Wing Cheung Mak; Anthony Turner; Daniel Filippini; Mikhail Vagin; Man Bock Gu; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conducting polymer; Interface; Sensing; Biosensing; Bioelectronics;

   Sammanfattning : The routine measurement of significant physiological and biochemical parameters has become increasingly important for health monitoring especially in the cases of elderly people, infants, patients with chronic diseases, athletes and soldiers etc. Monitoring is used to assess both physical fitness level and for disease diagnosis and treatment.
