Microstructure characterization of corrosion behavior of an alumina forming austenitic (AFA) steel exposed to supercritical carbon dioxide was conducted at 450–650 °C and 20 MPa. At low temperature and short exposure times, the oxidation kinetics

Controlling the pH during workup allows synthesis of TPPTS. P(m-C6H4SO3Na)3, without interference from the oxide. The recrystallized yield is 70% based on P(m-C6H4SO3Na)3 3H2O from PPh3.

Reaction of CO with trans-Ir(CO)(Cl)(TPPTS)2 in DMSO and H2O give [Ir(CO)3(TPPTS)2]Cl (H2O and DMSO) and Ir(CO)2(Cl)(TPPTS)2 (DMSO only). In both solvents the carbonylation is reversed by passing N2 through the solution. In water, further reactions o

The water-soluble iridium complexes trans-Ir(CO)L2X (X = Cl, OH; L = PPh2(m-C6H4SO3K) (TPPMS), P(m-C6H4SO3Na)3 (TPPTS)) have been used to extend the range of solvent effect for H2 activation at an iridium(I) center and to examine the effect of pH cha

Iridium complexes containing the TPPMS ligand (TPPMS = PPh2(m-C6H4SO3K)) have been prepared and studied in DMSO and H2O as a comparison to the PPh3 analogues in toluene. Measurements of the pH of the complexes show that most are almost neutral, but I

As 193 nm immersion lithography continues to evolve, the need to understand the effect of the immersing liquid on the resulting photoresist properties continues to grow. With this in mind, the sorption of water (using both liquid and vapor environmen

A hybrid bilayer imaging approach has been developed which uses a thin radiation sensitive, single component, metal-organic precursor film in conjunction with a thicker organic planarizing etch barrier. Upon electron beam irradiation, the metal-organ

Once the design of a door sheetmetal and accessories is confirmed, the acoustics of the door system depends on the sound package assembly. This essentially consists of a watershield which acts as a barrier and a porous material which acts as an absor

Considerable difficulties and limitations are associated with the patterning of thick photoresist layers to generate high aspect ratio features in MEMS fabrication. Moreover, a large number of steps is needed to achieve the patterned MEMS structures.

PMOD (Photochemical Metal Organic Deposition)-based DTFI (Direct Thin Film Imaging) methodology is a demonstrated means for patterning organic materials on flexible (plastic) substrates. This process is used to pattern 1-micron features at an aspect
