- A prospective, randomized study comparing the compression hip screw with the Gamma nail in the treatment of 426 intertrochanteric fractures is reported. The median patient age was 80 years, and 71 % were women The compression hip screw operation took less time except in Evans Type 5 fractures. Blood loss generally was less in the compression hip screw group except in patients with Type 5 fractures. The most frequent surgical problem for patients in the Gamma group was problems with distal locking. Cephalic position of the femoral head screw and cut-out were seen more often in the Gamma nail group. The Gamma nail more frequently preserved the fracture position obtained perioperatively. Whether there was distal locking of the Gamma nail in unstable fractures did not seem to affect the healing rate. Additional fissures or fractures in the proximal femur occurred during five Gamma nail operations and two compression hip screw operations. Postoperative walking ability did not differ between the groups. At 6 months 88% of the fractures were healed. In less comminuted fractures, the compression hip screw method is the preferred method of treatment whereas the Gamma nail is an alternative treatment for more comminuted Evans Type 5 fractures.

Journal article (peer-reviewed)abstract
- In a laboratory investigation using tunable picosecond lasers in a pump-probe configuration, lifetimes of the E 1u, v = 0 and v = 1 states of CO are experimentally determined. For E 'D, v = 1, the lifetime is found to vary significantly for the isotopomers. Combining the data with existing oscillator strengths, predissociation probabilities within the range of 93.6%-98.6% result for 12C16O, 13C16O, and 13C18O in the case of the E 1u, v = I state, which is the state that predominantly influences the isotopic fractionation of CO in interstellar clouds.

Iron-mediated growth of epitaxial graphene on SiC and diamond
- 2012

In: Carbon. - : Elsevier BV. - 0008-6223. ; 50:14, s. 5099-5105

Journal article (peer-reviewed)abstract
- Ordered graphene films have been fabricated on Fe-treated SiC and diamond surfaces using the catalytic conversion of sp(3) to sp(2) carbon. In comparison with the bare SiC(0 0 0 1) surface, the graphitization temperature is reduced from over 1000 degrees C to 600 degrees C and for diamond (111), this new approach enables epitaxial graphene to be grown on this surface for the first time. For both substrates, a key development is the in situ monitoring of the entire fabrication process using real-time electron spectroscopy that provides the necessary precision for the production of films of controlled thickness. The quality of the graphene/graphite layers has been verified using angle-resolved photoelectron spectroscopy, scanning tunneling microscopy and low energy electron diffraction. Graphene is only formed on treated regions of the surface and so this offers a method for fabricating and patterning graphene structures on SiC and diamond in the solid-state at industrially realistic temperatures.
