No full textEncolapta valvispinata (Li, 2002) comb. nov. (Figs 33, 47, 58) Homoshelas valvispinata Li, 2002a: 376. Type material. CHINA: Holotype Ƌ, Dongtang, Maolan National Nature Reserves, Guizhou Province, 23.v.1998, leg. Qirong Liao, genitalia slide no. L99078.

Diagnosis. Adult (Fig. 33) with wingspan 14.0−18.0 mm. This species can be easily separated from other known Encolapta species in the male genitalia by the valva with six long spines on the inner surface (Fig. 47), and in the female genitalia by the ductus bursae sclerotized distally (Fig. 58). Distribution. China (Guangxi, Guizhou). Remarks. Encolapta valvispinata is transferred from Homoshelas. Its 2nd palpomere possesses long loose scale tuft on the ventral surface, which is similar to members of the tegulifera -group. However, its forewing patterns, venation and genital characters are more similar to those of the members in the epichthonia -group, based on which we here place it in the epichthonia -group.Published as part of Yang, Meiqing & Li, Houhun, 2016, Review of the genus Encolapta Meyrick, 1913 (Lepidoptera: Gelechiidae: Chelariini) from China, with descriptions of six new species, pp. 201-227 in Zootaxa 4193 (2) on page 226, DOI: 10.11646/zootaxa.4193.2.1, http://zenodo.org/record/16686
Application of laser-based diagnostics for nanomaterials synthesis:
No full textSpectroscopic laser-based diagnostics are applied in the gas-phase synthesis of nanostructrued materials to make non-intrusive, in-situ, spatially-precise measurements of gas-phase temperatures and relevant chemical species. For the nanomaterials themselves, a novel application of Raman spectroscopy is developed to characterize nanoparticles in-situ, during flame and plasma synthesis. As result, the local conditions for gas-phase synthesis can be determined for a given nanomaterial property, so that fundamental mechanisms can be revealed and process conditions can be optimized.
The synthesis configurations investigated in this work are (i) the inverse co-flow diffusion flame (IDF), (ii) the counter-flow diffusion flame (CDF), (iii) the low-pressure burner-stabilized premixed stagnation-point flame, and (iv) the inductively-coupled plasma (ICP) impinging on a cold substrate.
Spontaneous Raman spectroscopy (SRS) is used to measure local gas-phase conditions in the 2-D axi-symmetric IDF and the quasi 1-D CDF, where nanomaterials are grown on inserted substrates of various compositions. Nitrogen-diluted methane-air flames are examined. Carbon nanotubes (CNTs) are grown catalytically on metal-alloy substrates, and their morphologies are correlated with the local gas-phase temperature and the concentrations of carbon-based precursor species (e.g. C2H2, CO). Zinc oxide (ZnO) nanostructures are grown directly on zinc-plated steel substrates, and their morphologies are correlated with the local gas-phase temperature and the concentrations of oxidative (e.g. O2, H2O, and CO2) and reducing (e.g. H2) species. Computational simulations in 1-D, involving detailed chemical kinetics and transport properties, and in 2-D, using simplified kinetics and transport, are used to validate and improve the measurements.
Laser-induced fluorescence (LIF) is employed to measure the gas-phase temperature profile and OH radical species concentration distribution in a low-pressure, premixed, nitrogen-diluted hydrogen-oxygen, burner-stabilized, stagnation-point flame. Titania nanoparticles are synthesized using a metalorganic precursor. The LIF measurements are compared with computational simulations with detailed chemical kinetics and transport, to affirm the quasi 1-D flow field, as well as to investigate the effects of precursor addition and uniform electric-field application.
SRS is utilized to characterize in-situ the composition and crystallinity of nanoparticles, in aerosol form, produced in the aforementioned low-pressure premixed flame and in the ICP synthesis setup. The Stokes spectra are identified for crystalline phases of TiO2 (and Al2O3 in a different flame setup) and c-BN based on ex-situ-taken spectra from the literature. The in-situ technique is able to delineate the phase conversion of nanoparticles (including amorphous to crystalline) as they evolve in the flow field.Ph.D.Includes bibliographical referencesby Xiaofei Li

No full textThe Works of Li Qingzhao
No full textThis volume is a translation of the song lyrics, poetry, and prose of Li Qingzhao (1084-1150s), with annotations and an introductory critical essay. Her song lyrics and poetry will be presented in a way to help readers get beyond traditional conventional images of her and gain insight into her originality and importance as a female voice in a literary world of her time that was almost exclusively male
