Magnetotransport Studies of Mn Ion-Implanted Nanowires

Popular Abstract in Swedish Den pågående trenden att alltmer digital information skapas och lagras av ett ständigt ökande antal människor över hela världen driver på den formidabla utveckling vi idag ser av elektroniska apparater som t.ex. läsplattor, bärbara datorer och smartphones. För att möjliggöra en fortsatt utveckling i samma takt, krävs tillgång till nya typer av halvledarkomponenter och kThis thesis focuses on the magnetotransport properties of highly Mn-doped crystalline GaAs nanowires. The GaAs nanowires were first grown by metal-organic vapor phase epitaxy from gold seed particles, and subsequently implanted with Mn ions under varying conditions, e.g., ion fluence and acceleration voltage. The implantation process was carefully analyzed and optimized within the research project

Natural Radiative Lifetimes of Some Excited Bi I Levels Belonging to the 6p^(2)7s and the 6p^(2)6d Configurations Measured by the Hanle Method

The natural radiative lifetimes of some excited Bi I levels belonging to the 6 p 2 7 s and the 6 p 2 6 d configurations have been determined by analyzing Hanle depolarization curves obtained in an atomic beam experiment on the 100% abundant isotope Bi 209 ( I =9/2). Taking the exciting light spectral distribution into account the following values for the lifetimes have been obtained: ##IMG## [http

Pyridine Nucleotides in Plant Mitochondria. Amounts, metabolism and contribution to electron transport

Popular Abstract in Swedish Mitokondrier är små stavformade eller runda organeller (0.5-2 µm). De producerar huvuddelen av den energi som krävs för cellens livsuppehållande processer. Antalet mitokondrier per cell kan variera med vävnadens energibehov. Ett exempel är människans spermie som innehåller ett stort antal mitokondrier vilka behövs för producera den energi som åtgår när spermien simmar tHPLC analysis was used for direct quantification of amounts and redox levels of pyridine nucleotides in plant mitochondria. The amount of NAD(H) and NADP+ varied, 1.0-3.7 and 0-0.5 nmol (mg protein)-1, respectively, depending on the species from which nucleotides were extracted. NADPH was never detected. Submitochondrial localisation of NAD+-degrading enzymes indicated that matrix NAD+ diffuses i

Technical results from Manus user trials

Eight users have tried the Manus arm at the Department of Rehabilitation at Lund University Hospital. The user trials were carried out in close co-operation with Certec at Lund University. After the trials one of the users, Ms Eva Gerdé, decided to buy a Manus arm, and she received her Manus arm in November 1998. The main objective of the user trials was to find out how robot technology could
