Significance and Use 5.1 Infrared techniques frequently cannot detect low-level materials. Gas chromatographic methods possess higher sensitivity, and are used to extend limits of detection. 5.2 It is expected that this test method will be suitable for s
The cover picture shows that a transparent and UV-shielding Epoxy/SR-494/APTMS/ZnO nanocomposite with high heat resistance and anti-static properties was prepared. The ZnO fillers could covalently bound to epoxy/SR-494 organic copolymer matrixes which were also enhanced to perform the hypercrosslinked structures in th…
Significance and Use 5.1 This test method is a useful adjunct to dynamic thermal tests that are performed under conditions in which the sample temperature is increased continuously at a programmed rate. Results obtained under dynamic test conditions prese
This specification covers a group of common requirements that, unless covered by the individual product specification in another ASTM document, applies to steel and alloy castings for use in general industrial applications. Materials shall be produced by open-hearth or electric furnace process with or without separate…
Structure and orientation evolution of the Al2Cu phase dendritic in smaller size sample during directional solidification
This specification covers chromium-nickel stainless steel plate, sheet, and strip, modified by the addition of natural or enriched boron, for nuclear application. The austenitic chromium-nickel steels shall be solution annealed to meet the mechanical property requirements. The chemical analysis of representative mater…
Featured article: Self-folding polymer films are extremely attractive for 3D microfabrication and are able to form different structures ranging from simple tubes to highly complex 3D shapes.This review summarizes our recent progress in the design of such films bilayers and understanding of their behavior.
In this work, graphene oxide was used as the precursor, and gallic acid (GA) was used as the reducing agent and stabilizer to obtain the reduced graphene oxide by water bath heating method. Ultraviolet visible absorption spectrum, Fourier transform infrared spectrum, Raman spectroscopy, X-ray diffraction and scanning…
Reaction of tetrachlorogermane with 2-thienylchlorosilane and methyl(2-thienyl)dichlorosilane in presence of AlCl 3 is studied. It was shown that in the reaction with 2-thienyltrichlorosilane 2-thienyltrichlorogermane mainly formed, while in the reactions with methyl(2-thienyl)dichlorosiulane aromatic germaniumcontain…
The cover picture illustrates a novel procedure for the preparation of covalently linked capillary coatings of poly(N-vinyl aminobutyric acid) (PVAA, green layer) using the layer by layer self-assembly technique with photosensitive diazoresin (DR, red layer) as coupling agents. The covalently bonded coatings can suppr…
Present study highlights the flow control effectiveness of newly designed synthetic–jet–actuator (SJA) arrays placed at 23% and 43% of the chord from the leading edge of a low-speed wing model. First, the characteristics of a single SJA were investigated under the quiescent-flow condition. It was found that the jet ve…
fondamentale à la production d'énergie ?, Rapport scientifique et technique n°26 de l'Académie des sciences, EDP Sciences (2007).« Avec ITER et les machines satellites, tous les aspects scientifiques et techniques de la filière tokamak auront été mis à l'épreuve, sauf un : la tenue des matériaux, notamment ceux de la…
Significance and Use 5.1 Adhesives can be exposed to both electrical potential and humidity in many electrical and electronic applications. It is therefore desirable to provide a means of examining the corrosive tendencies of certain adhesives towards met
1. Theoretical study of insulating mechanism in multi-orbital Hubbard models with a large spin-orbit coupling: Is Sr2IrO4 a Slater insulator or a Mott insulator? Authors: Hiroshi Watanaebe, Tomonori Shirakawa, Seiji Yunoki arXiv:1402.0935 2. Bulk Nature of Layered Perovskite Iridates beyond the Mott Scenario : An Appr…
This specification covers electric-fusion-welded austenitic chromium-nickel stainless steel pipe suitable for corrosive or high-temperature service, or both, or for general applications. The pipes shall be sorted into five different classes. Class 1 pipes shall be double welded by processes employing filler metal in a…
Significance and Use 5.1 The methods outlined in this guide can be used to qualitatively and quantitatively evaluate the sensory characteristics and performance of trigger hard surface household cleaning products for nonporous surfaces. 5.2 The methods a
This issue of Macromolecular Reaction Engineering contains articles of the Special Series “Polyolefins – Catalyst and Process Innovations”.
Six high aluminum AlCr targets equally containing 5 at.% of Ti, V, Y, Nb, Mo and W respectively, were used to deposit alloyed aluminum chromium nitride thin films using the reactive cathodic arc deposition technique. Although the NaCl-type crystal structure was maintained for these transition metals, X-ray diffraction…
Significance and Use 4.1 This test method measures the relative abrasion resistance of various refractory samples under standard conditions at room temperature. 4.2 The abrasion resistance of a refractory material provides an indication of its suitabili
This report, in fulfillment of a license requirement, presents the results of long-term surveillance and maintenance activities conducted by the U.S. Department of Energy (DOE) Office of Legacy Management (LM) in 2013 at 19 uranium mill tailings disposal sites established under Title I of the Uranium Mill Tailings Rad…
