We report on ZnO nanorods grown by catalyst-free metal-organic chemical vapour deposition (MOCVD) in a commercial Epigress reactor using diethylzinc and N2O as precursors. Well-aligned ZnO nanorods with uniform diameter, length and density have been grown perpendicularly to the sapphire (0 0 01) surface. Scanning electron microscopy (SEM) has been used to(More)
Thirty patients with lower extremity ulcers of different aetiologies, although mainly of venous origin, were treated with an occlusive hydrocolloid dressing twice a week for a maximum period of 12 weeks. No antibacterial chemotherapy was utilized. A culture was taken of the exudate of the ulcer before commencement of treatment and weekly or bi-weekly(More)
We report on the collective integration technology of vertically aligned nanowires (NWs). Si and ZnO NWs have been used in order to develop a generic technological process. Both mineral and organic planarizations of the as-grown nanowires have been achieved. Chemical vapour deposition (CVD) oxides, spin on glass (SOG), and polymer have been investigated as(More)
We show that the molecule-like configuration of DD∗ enables weak binding even in the case of the Bhaduri or Grenoble AL1 interaction. Three-body forces may increase the binding and strengthen the cc diquark configuration. As a signature we propose the branching ratio between radiative and pionic decay.
Since 1981 we monitored all the bacteria strains isolated from patients bearing a surgical infection and hospitalized in our department. We also tested the susceptibility of the isolated strains to different antibiotics. The observed results at three different intervals (1981, 1984, 1987-1988) reveal an increase in Gram+strains. Among the tested antibiotics(More)
