1. Spin Transport Studies of Nanoscaled Ferromagnetic Tunneling Devices
Sammanfattning : This thesis presents spin transport studies of ferromagnetic nano-scaled tunneling devices fabricated by atomic force microscopy (AFM) and electron beam lithography (EBL). The thesis covers three main topics: The first topic is a study of spin accumulation (relaxation) in Au nano-structures using Ni/Au/Ni ferromagnetic single electron transistors (F-SETs). LÄS MER
2. Regulatory Functions of the Juxtaglomerular Apparatus
Sammanfattning : The tubuloglomerular feedback mechanism is an important regulator in the juxtaglomerular apparatus and it detects flow dependent alterations in luminal NaCl concentration ([NaCl]) at the macula densa (MD) cell site via a Na+-K+-2Cl cotransporter. Signals are sent by the MD to adjust the afferent arteriole tone and altering release of renin. LÄS MER
