    Title: Ordering of self-assembled 5-nm-diameter poly(dimethylsiloxane) nanodots with sub-10 nm pitch using ultra-narrow electron-beam-drawn guide lines and three-dimensional control
    Author: Zhang, Hui; Hosaka, Sumio; Yin, You
    Subject: Nanoscience And Nanotechnology ; Control ; Electron Beams ; Masking ; Polystyrene ; Quantum Dots ; Thickness ; Thin Films ; Engineering ; Physics
    Description: We demonstrate the possibility of forming long-range ordered self-assembled arrays of 5-nm-diameter nanodots with pitch of 10 × 7.5 nm{sup 2} using guide line templates and low molecular weight (MW) (4700–1200 g/mol) poly(styrene)-poly(dimethylsiloxane) (PS-PDMS) for application in ultrahigh density patterned magnetic recording media. We propose a three-dimensional control which involves control of the height of the guide lines, the thickness of the PS-PDMS films, and the gap between the guide lines in order to produce 5-nm-diameter, sub-10 nm pitched nanodots with long-range order along the guide lines. Adopting a 13-nm-thick PS-PDMS film and 14-nm-high resist guide lines, the 5-nm-diameter and 10 × 7.5 nm{sup 2}-pitched self-assembled nanodots were ordered in 4–7 dot arrays with long-range order. The experimental results demonstrate that the method is suitable for the production of patterned media with magnetic recording densities of 8.6 Tbit/in.{sup 2} using low MW PS-PDMS and slim guide lines.

    Description: The precipitation kinetics and its effect on hot working behavior of an Al–Zn–Mg–Cu alloy were studied under non-isothermal conditions and over a wide range of temperatures. The characterization techniques employed included in situ electrical resistivity measurements, differential scanning calorimetry, hardness testing and microstructure examination by scanning and transmission electron microscopy. The results showed that the precipitation kinetics during non-isothermal treatments were highly dependent on the thermal paths. Slow cooling processes led to coarse and sparse particle distribution. When heating to high temperatures, very fine precipitates with high density and homogeneous distribution were present at low temperature. Such fine precipitates showed unstable characters and dissolved quickly at higher temperature. Quantification of precipitate evolution during non-isothermal processing was obtained from in situ electrical resistivity measurements. The effects of heating paths on dynamic and static flow behaviors were also demonstrated to be significant. The degree of initial supersaturation controlled the nucleation rates and led to strong effect on dynamic and static precipitation, and on the flow stress softening.

    Title: Probing the activity of Ni 13 , Cu 13 , and Ni 12 Cu clusters towards the ammonia decomposition reaction by density functional theory
    Author: Chen, Shuangjing; Chen, Xin; Zhang, Hui
    Subject: Ammonia ; Density Functional Theory ; Dehydrogenation;
    Description: By means of density functional theory, the ammonia decomposition reactions catalyzed by Ni 13 , Cu 13 , and Ni 12 Cu clusters have been studied and compared. We firstly investigated the structural stability of these clusters, and then systematically investigated their ammonia decomposition activity by analyzing the adsorption property of reaction intermediates and the relative energy diagram. The results show that the adsorption energy of reaction intermediate N on Ni 12 Cu cluster is −5.93 eV, which is very close to the optimal value (−5.81 eV) of ammonia decomposition volcano curve. The reaction energy diagram shows that the dehydrogenation of NH intermediate is the rate-determining step for these clusters due to the positive reaction heat. Furthermore, the catalytic property of Ni 12 Cu cluster is interpreted by density of states. It indicates that the adsorption energies of reaction intermediates mainly depend on the d-band center of the clusters.

    Description: A cobalt(II) tetra-neopentyloxy phthalocyanine-multi-walled carbon nanotubes (CoTNPPc–MWNTs) composite was synthesized and characterized by UV–Vis spectra and transmission electron microscopy. The CoTNPPc–MWNTs glassy carbon electrode (CoTNPPc–MWNTs/GCE) was prepared by drop coating. The electrocatalytic performance of the chemically modified electrode was investigated for oxidation of ascorbic acid (AA). It was found that in phosphate buffer solution at pH = 6.60, the chemically modified electrode exhibited excellent electrocatalytic activity toward the oxidation of AA. The oxidation peak current increased linearly with the concentration of AA in the range of 10 μM–1.6 mM within the detection limit of 5 μM and low response time of 4 s.

    Title: Multivariate analysis of modern and fossil pollen data from the central Tianshan Mountains, Xinjiang, NW China
    Author: Zhang, Yun; Kong, Zhaochen; Zhang, Hui
    Subject: Vegetation Dynamics -- Analysis ; Climate Change -- Analysis ; Rain -- Analysis ; Peat -- Analysis;
    Description: To interpret past vegetation and climate changes from pollen data, we need to reveal the degree of similarity between modern analogues and fossil pollen spectra, which would help us predict the future climate and vegetation. Ninety surface pollen samples across six vegetation zones along an altitudinal gradient from 460 to 3510 m and 44 fossil samples at Caotan Lake were collected in the central Tianshan Mountains, northern Xinjiang, China. Discriminant analyses results, fossil pollen and phytolith assemblages were then used to reconstruct palaeovegetation and palaeoclimate in the area. The 90 surface samples were divided into six pollen zones (alpine cushion, alpine and subalpine meadow, montane Tianshan spruce forest, forest-steppe ecotone, Artemisia desert, typical desert), corresponding to the major vegetation types in the area. These zones follow a climatic gradient of increasing precipitation with increasing elevation. Paleovegetation reconstructed from 44 fossil pollen assemblages through discriminant analysis reflects the regional vegetation shifted from typical desert to Artemisia desert since 4640 cal. year BP in the Caotan Lake wetland. The fossil pollen and phytolith record also reveal the arid climate has not fundamentally changed in the period. But a dry-wet-dry local climate oscillation since 2700 cal. year BP has a fundamental influence on local wetland vegetation dynamics and peat accumulation of the Caotan wetland. Modern wetland landscape and surface pollen assemblages from the Ebinur Lake Wetland Nature Reserve provide further evidence for ferns and Betula growing in the Caotan Lake wetland during the historical period.
