36. Supersonic Nanocrystal Deposition for Nanostructured Materials

Abstract

We experimentally demonstrate the large scale production and controlled collection of metal and semiconductor nanocrystals by laser ablation of microparticles entrained at high density in a flowing aerosol. For silver, produced nanocrystals exhibit bimodal, log-normal size distributions. Mean particle sizes are controlled from 3-16 run by varying the type and pressure of carrier gas as well as laser fluence. For collection, a micronozzle orifice (d = 200 micrometers) accelerates nanocrystals through a sonic jet into a vacuum chamber for deposition onto a room temperature substrate. We describe two regimes of deposition that depend on the nanocrystal's energy per atom on impact. Soft landings (E < < 1 eV/atom) preserve the individual particle properties such as size and shape. Low energy impaction is demonstrated for CdSe in an argon carrier gas. The CdSe nanoclusters remain crystalline upon deposition and display visible photoluminescence. At higher particle impaction velocities (E ^ 0.3 eV/atom) nanocrystals exhibit the onset of self sintering upon impact. At high number densities, adherent, conductive lines are formed from deposited silver nanocrystals. Line widths of 33 micrometers FWHM are directly written onto substrates using a 200 micrometers diameter nozzle., Pub in: Materials Research Society Symposium Proceedings, Volume 703.

Abstract

Analyses were conducted to evaluate the ability of the USDA yield grade equation to detect differences in subprimal yield of beef–type steers and calf–fed Holstein steers that had been fed zilpaterol hydrochloride (ZH; Intervet Inc., Millsboro, DE) as well as those that had not been fed ZH. Beef–type steer (n = 801) and calf–fed Holstein steer (n = 235) carcasses were fabricated into subprimal cuts and trim. Simple correlations between calculated yield grades and total red meat yields ranged from –0.56 to –0.62 for beeftype steers. Reliable correlations from calf–fed Holstein steers were unobtainable; the probability of a type I error met or exceeded 0.39. Linear models were developed for the beef–type steers to predict total red meat yield based on calculated USDA yield grade within each ZH duration. At an average calculated USDA yield grade of 2.9, beef–type steer carcasses that had not been fed ZH had an estimated 69.4% red meat yield, whereas those fed ZH had an estimated 70.7% red meat yield. These results indicate that feeding ZH increased red meat yield by 1.3% at a constant calculated yield grade. However, these data also suggest that the calculated USDA yield grade score is a poor and variable estimator (adjusted R2 of 0.31 to 0.38) of total red meat yield of beef–type steer carcasses, regardless of ZH feeding. Moreover, no relationship existed (adjusted R2 of 0,00 to 0.01) for calf–fed Holstein steer carcasses, suggesting the USDA yield grade is not a valid estimate of calf–fed Holstein red meat yield.

Abstract

Laser morphological manipulation has been performed on gold nanoparticles periodically arranged on solid supports by nanosphere lithography. It is shown that third harmonic Nd:YAG pulse laser irradiation (15 mJ/cm2 per pulse) leads to an evolution from the initial polycrystalline, triangular shaped particles to spherical single crystalline particles. These morphological changes are accompanied by a significant change in the optical absorption properties of the array. This study demonstrates that laser irradiation is an excellent technique to control the properties of nanostructured materials on solid supports. Further, it is suggested that the selected area treatment possible with the laser is a valuable new technique for designing functional nanomaterials for applications such as high-density data storage devices.

Abstract

Nanoparticles of TiO2 and SnO2 were obtained by laser ablation of Ti and Sn targets in both deionized water and sodium dodecyl sulfate (SDS) solutions. The crystallinity of the nanoparticles strongly depended on the SDS concentration in the solution. Well-crystallized oxide nanoparticles were most abundantly fabricated in SDS solution with around the critical micelle concentration. An inorganic/organic layered nanocomposite consisting of a zinc hydroxide layer and a SDS lamellar interlayer was obtained by the ablation of Zn in SDS solutions. The oxide and/or hydroxide can be formed by the rapid reactive quenching with water in the liquid–plasma interface, where ablated species can be oxidized by aqueous oxidation. The surfactant in the liquid medium could affect the aggregation and growth of nuclei after the oxidation. The preparation of Pt/TiO2 nanocomposite particles by PLA of the bi-combinant target of Pt and TiO2 is also reported. [ABSTRACT FROM AUTHOR]
