The effects of temperature and chloride deposition on hydrogen absorption into steel were evaluated during wet/dry cyclic corrosion using a temperature-compensated monitoring system based the electrochemical permeation method. Hydrogen was detected through measurement currents wet periods under corrosion. enhancement mainly caused by changes in solution chemistry wetting drying periods, with de...

stoichiometric tetragonal bal-xsrxtio3 (x = 0.23) nanopowders were prepared by stearic acid gel(sag) method using barium stearate, strontium stearate, tetrabutyl titanate as ba, sr, ti sourcesand stearic acid as complexing reagent. thermal analysis including differential thermogravimetric(dtg) and tg, fourier transform infrared spectrometry (ftir), x-ray diffraction (xrd) andtransmission electr...

The occurrence of galvanic corrosion on compound semiconductor substrates with exposed metal has been observed as deleterious device effects. Noble metals, e.g. gold, platinum, etc., in contact with exposed GaAs can induce undesired galvanic etching during wet process steps and result in surface irregularities that adversely affect yield. This phenomenon can occur when stripping photoresist usi...

Title of Dissertation: STUDY OF WET-CHEMICALLY-PREPARED HYDROGEN-TERMINATED SILICON (111) SURFACES AND A NOVEL IMPLEMENTATION OF A HIGH-RESOLUTION INTERFEROMETER Hui Zhou, Doctor of Philosophy, 2003 Dissertation directed by: Dr. Richard Silver Chemical Physics Program This thesis summarizes my graduate study under the National Institute of Standards and Technology (NIST) Atom-Based Dimensional ...

Maintaining animal health and performance relies on the availability of an appropriate diet. For herbivores, accurate assessment forage nutrient quality is critical for diet formulation rationing, including potential supplementation. Near-Infrared Reflectance Spectroscopy (NIRS) a rapid method that used in place traditional chemical methodologies (wet chemistry) to predict analyte contents samp...

Graphene-based materials are elective materials for a number of technologies due to their unique properties. Also, semiconductor nanocrystals have been extensively explored due to their size-dependent properties that make them useful for several applications. By coupling both types of materials, new applications are envisaged that explore the synergistic properties in such hybrid nanostructures...
