Title: Platinum Electrodeposition for Supported ALD Templated Foam Hohlraum Liners

Abstract

Two commercially available platinum plating solutions (Platanex III and Platanex Luna) were evaluated for the electrodeposition of platinum layers on gold hohlraums and cylindrically shaped silver-gold ingots. The successful deposition of thin Pt layers on gold hohlraums as well as thick Pt layers on silver-gold alloys will allow for the integration of atomic layer deposition templated foam inside a hohlraum. We found that when the manufacturer’s recommendations for the Pt plating solutions were used, the coatings obtained were unacceptable because of cracking, poor adhesion, or thin and powdery Pt deposits. Therefore, alternative plating parameters were investigated, and the conditions resulting in acceptable coatings are reported here.

  • Backlighting of low-density SiO[sub 2] aerogel balls (0.3 g/cc) in Nova hohlraums enables direct imaging of the indirectly driven ablative shock trajectory versus time. An immediate application of the technique is a new method for measuring drive temperature and asymmetry in Nova hohlraums. Measured drive asymmetries are exaggerated due to an increased shock speed in low-density foam balls. From the backlighter-imaged distortion of the radially converging shock, a potentially useful time-dependent flux asymmetry diagnostic is obtained. Results from a 3:1 peak-to-foot contrast ratio pulse shape ([ital ps]22) are analyzed and shown to agree with modeling. The current goal of themore » witness-ball effort on Nova is to identify the transition in flux on capsule from waist high (sausaging) to pole high (pancaking), thereby validating the technique as a promising symmetry diagnostic for the proposed National Ignition Facility.« less
  • Supported Pt catalysts were modified by adding a second metal such as Co, Mo, Ni, Re, Ag, and Pd. The effects of a second metal on the sulfur resistance were first investigated by accelerated aging test reactions. The test reactions were hydrogenation of tetralin containing 1,000 ppm sulfur at 280 C, 380 psig, and H{sub 2}/oil (mol) = 2.7. The results indicated that Pd-Pt catalyst had the highest sulfur resistance. Aromatics reduction, hydrodesulfurization, and hydrodenitrogenation of straight run distillate diesel over supported Pt and Pd-Pt catalysts were further examined by long-term stability tests. The operation conditions of these tests aremore » the same as those run in a commercial diesel hydrotreating process. The results again indicated that the Pd-Pt catalyst exhibited much better catalytic performance. These results, together with electronic properties of the metal clusters on the catalysts characterized by FFT-IR spectroscopy, provide a basis to speculate the role of Pd in enhancing sulfur resistance; the Pd-Pt bimetallic interactions decrease the electron density of Pt and thereby inhibit the adsorption of H{sub 2}S.« less

  • We present density-functional-theory calculations of structural, electronic, and magnetic properties of platinum-alloy strings templated on a boron-doped single-wall carbon nanotube (6,6) model, B-SWCNT(6,6). Our calculations show that the alloy strings demonstrate strong molecular recognition, forming well-defined covalent bonds with the substrate and lead to the self-assembly of stable monatomic chains. The electronic and magnetic features of the Pt-alloy string/B-SWCNT(6,6)composite systems are mainly controlled by the presence of a magnetic alloying element (i.e., Fe, Co, and Ru). By changing the composition of the Pt alloy, the easy magnetization axis of the system can oscillate between the directions parallel and perpendicular tomore » the tube axis. Our studies suggest that pure transition-metal (TM) or TM-alloy strings anchored on a substrate via strong molecular interactions can still possess sizable magnetic anisotropy due to spin-orbital coupling effects.« less
