Crystal Structure of a Sodium Sorption Complex of Zeolite X Containing Linear Na32+Clusters
An anhydrous single crystal of sodium zeolite X, Na 92 Si 100 Al 92 O 384, was exposed for 48 h to Na vapor at 225 °C. Its structure was determined by X-ray diffraction methods in the cubic space group Fd 3̄; a = 25.100(11) Å at 22 °C; R 1 = 0.071 and R 2 = 0.088 for the 544 reflections for which I > 3σ( I ). A total…
Conducting Polymer Color Sensor
A color sensor device using conducting polymer poly(3-hexylthiophene) (PAT6), has been fabricated and characterized. The device consists of two photocells made of the same conducting polymer with different polymer thicknesses, and which exploits the difference in the photocurrent spectrum of the photocells. The color…
A Processable Mullite Precursor Prepared by Reacting Silica and Aluminum Hydroxide with Triethanolamine in Ethylene Glycol: Structural Evolution on Pyrolysis
A simple, processable precursor to mullite can be synthesized in quantities of 100 g in a few hours by direct reaction of silica, aluminum hydroxide, and triethanolamine in ethylene glycol. To delineate a processing window whereby precursor shapes can be transformed into mullite, the chemical and phase microstructural…
Crystal Structures of Dehydrated Fully Mn2+-Exchanged Zeolite X and of Its Ethylene Sorption Complex
The crystal structures of dehydrated Mn 46 Si 100 Al 92 O 384 ( a = 24.721(5) Å) and of its ethylene sorption complex Mn 46 Si 100 Al 92 O 384 ·30C 2 H 4 ( a = 24.690(5) Å) have been determined by single-crystal X-ray diffraction techniques in the cubic space group Fd 3̄ at 21(1) °C. Each crystal was prepared by dehyd…
The concept of cohesional entanglement
Abstract A concept of cohesional entanglement through local nematic interaction of neighboring chain segments has been introduced in addition to the usual topological entanglement of chains. As topological entanglement is important to properties of the polymer in the rubbery and flowing states at temperatures well abo…
Experience and assessment of stress corrosion cracking in L-grade stainless steel BWR internals
The stress corrosion cracking (SCC) rate of reactor internals of boiling water reactors (BWR) continues to increase with on-line operating years. The recent occurrences of cracking in the weld heat affected zones of high carbon stainless steel core shrouds correlate with the years of operation and the water chemistry…
