This specification covers double pour, centrifugally cast, abrasion-resistant roll shells for general application. The outer layer is white iron and the inner layer is gray iron and there shall be no gradient of mottled iron these layers. Both the white and the gray irons may be melted by any suitable melting process.…
The Affiliate Plan, established by the IEEE Board of Directors, enables individuals who are not members of the IEEE, but who have an interest in the field of plasma science, to join the IEEE Nuclear and Plasma Sciences Society. Admission as an affiliate requires only membership in a professional society listed below.…
Femtosecond lasers have considerable advantages over conventional lasers for micromachining of transparent materials, and here we use these advantages to fabricate a new type of glass capillary tube with micro- and nanopatterns on the inner surface of the tube. In terms of femtosecond laser patterning, we focused on t…
US-based Entegris Inc used the SEMICON Taiwan tradeshow, held recently in Taipei, to exhibit its 10-nm-rated Intercept HPM liquid filter that has been developed for use in demanding applications in semiconductor manufacturing.
Thin films of CuIn 1- x Al x Se 2 (CIAS) were prepared by stacked elemental precursor layers in an inert ambient. The stacking sequence of precursor layers may affect the kinetics of phase formation. The soda lime glass (SLG)/Cu/Al/In/Se sample heated at 750 °C for 30 s with a temperature ramp rate of 15 °C/s may reac…
We report the enhanced light output power of InGaN/GaN light-emitting diodes (LEDs) with ZnO nanorods grown on the polished rear side of the sapphire substrate. ZnO seeds were spin coated on the polished bottom side of the sapphire substrate and a simple solution technique was employed to grow ZnO nanorods. Results re…
A new structurally unique form of carbon that has both crystalline and disordered elements has been created by researchers from the US and China. The material is hard enough to indent diamond and is known as ordered amorphous carbon clusters, or OACC.
Significance and Use 4.1 Significance—This classification establishes an alphanumeric code of the tempers of copper and copper alloy products. 4.2 Use—An alphanumeric code establishes a system by which product tempers in specifications and published dat
This specification establishes the requirements for wire in round, hexagonal, octagonal, rectangular, and square form of UNS Alloy Nos. C71000, C74500, C75200, C75700, C76400, C77000, and C79200. The chemical composition, temper, annealed wire grain size, tensile strength, and bending requirements are detailed.
Abstract DMV 600L is a nickel alloy with 15.5 Cr. The alloy is used mainly as a material resistant to aqueous corrosion at temperatures below 450 deg C (842 deg F). This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on high temperat…
This fact sheet gives an overview of the technical assistance provided by DOE/NREL to the Department of Defense to advance energy security. Specifically, the fact sheet describes the net zero energy project at the U.S. Marine Corps Air Station (MCAS) Miramar.
Starting in mid-September, the European Hydrogen Road Tour 2012 travelled through Germany to Italy, then back up through France and across the UK before arriving four weeks later in the Danish capital, Copenhagen. The Tour also offered seminars and ride & drive events for policy-makers, industry representatives, press…
Significance and Use 3.1 The modulus of rupture of carbon-containing refractories at elevated temperatures has become accepted as a useful measurement in quality control testing and in research and development. These measurements are also used to determi
Scope1.1 This terminology and acronyms standard covers and defines commonly used terms and acronyms in the field of corrosion. Related terms may be found in Terminologies D16, D4538, G40, or other ASTM terminology standards. 1.2 This terminology and acron
Significance and Use 6.1 Means for selecting and identifying nonrigid vinyl chloride compounds are provided in Table 1. The properties enumerated in this table and the tests defined are expected to provide identification of the compounds selected. They ar

Europium(III) derivative formed by reaction of the europium ion with a fluorinated diketonate reagent and a neutral donor. The resulting non-polar, thermally stable, and luminescent derivative partitions into cyclohexane upon formation and can be subjected to high-resolution capillary gas chromatography. This approach…
