The electrical and structural characteristics of thin p + layers have been measured by FPP (four point probe), SRP (spreading resistance probe), RBS/channelling. Optimizing the implantation and annealing processes, especially using the thermal cycle of RTA followed by FA, shallow p +n junctions can be fabricated, which shows excellent I V characteristics with revers bias leakage current densities of 1.8?nA/cm 2 at -1.4?V.展开更多

The commonest etiology is intervention for localized prostate cancer and/or radical cystoprostatectomy for muscle invasive bladder cancer. Despite advances in surgical technology with robotic assisted laparoscopic prostatectomy and nerve sparing techniques, the rates of ED and SUI remain relatively unchanged. They both impact greatly on quality of life domains and have been associated with poor performance outcomes. Both the artificial urinary sphincter and penile prosthesis are gold standard treatments with proven efficacy, satisfaction and durability for end-stage SUI and ED respectively. Simultaneous prosthesis implantation for concurrent conditions has been well described, mostly in small retrospective series. The uptake of combination surgery has been slow due in part to technical demands of the surgery and to an extent, a heightened anxiety over potential complications. This paper aims to discuss the technical aspect of concurrent surgery for both disease entity and the current published outcomes of the various surgical techniques with this approach.展开更多

The phase formation conditions for corrosion resistance and its effects were researched. The super-saturation solid station solution of Mo+ and C+ atoms was formed in Mo+C dual implanted steel. Precipitate phase with nanometer size Fe2Mo, FeMo, MoC, Fe5C3 and Fe7C3 were formed in dual implanted layer. The passivation layer consisted of these nanometer phases. The corrosion resistance of the dual implanted layer was better than that of single Mo implantation. Jp of the Mo implanted sample is 0.55 times that of H13 steel. The corrosion resistance of the dual implantation was enhanced when ion dose increased. When the Mo+ ion dose was 6×1017/cm2 in the dual implantation, Jp of the dual implanted sample was only 0.11 times that in H13 steel. What is important is that pitting corrosion properties of dual implanted steel were improved obviously.展开更多

The property of corrosion resistance dual-implanted (C+Ti) H13 steel is studied using multi-sweep cyclic voltammetry. TEM images of the cross section of an implanted sample reveal plenty of circular nanometer structures with diameters of 10–30 nm. The phases are densely embedded in the implanted layer. The embedded structure improves the surface corrosion resistance, as can be observed with a scanning electron microscope (SEM). The phases with the shape of a tiny wire in nanometer size are formed. The nanometer phases, consisting of TiC, FeTi and FeTi2, are formed in dual implanted layer. The corrosion current peak density decreases to 1/16–1/10 that of the unimplanted H13 steel. The formation conditions of the nanometer phases and their effects are investigated. The passivation layer consists of nanometer phases. The corrosion resistance of the dual implantation can be further enhanced with an increase in ion dose.展开更多
