Lithography Technique

ABSTRACTRecently, an inexpensive 3D lithography technique was developed by Professor Nicholas Fang at the University of Illinois where a projector is used in combination with a Microsoft® PowerPoint presentation to expose the liquid negative-tone photoresist 1,6-hexanediol diacrylate in a layer-by-layer fashion. Where Professor Fang initially used this method as a teaching tool, we have used the inexpensive 3D printing technique to create 3D structures of fumarate based polymers. This class of polymers are liquids at room temperature which makes them ideal for the projector based lithography technique when used in combination with the photoinitiator bisphenyl(2,4,6-trimethylbenzoyl)-phosphine oxide (BAPO). Furthermore, the fumarate based materials are biocompatible and are suitable candidates for tissue engineering applications.

Base Superalloy

Recently we have been investigating a class of nickel-base superalloys which possess substantial room temperature ductility. This improvement in ductility is directly related to improvements in grain boundary strength due to increased boundary cohesion through control of detrimental impurities and improved boundary shear strength by controlled grain boundary micros true tures.For these investigations an experimental nickel-base superalloy was doped with different levels of sulphur impurity. The micros tructure after a heat treatment of 1360°C for 2 hr, 1200°C for 16 hr consists of coherent precipitates of γ’ Ni3(Al,X) in a nickel solid solution matrix.

Cooling Fluid

A fire involving an electric service transformer and its cooling fluid, a mixture of PCBs and chlorinated benzenes, contaminated an office building with a fine soot. Chemical analysis showed PCDDs and PCDFs including the highly toxic tetra isomers. Guinea pigs were chosen as an experimental animal to test the soot's toxicity because of their sensitivity to these compounds, and the liver was examined because it is a target organ. The soot was suspended in 0.75% methyl cellulose and administered in a single dose by gavage at levels of 1,10,100, and 500mgm soot/kgm body weight. Each dose group was composed of 6 males and 6 females. Control groups included 12 (6 male, 6 female) animals fed activated carbon in methyl cellulose, 6 males fed methyl cellulose, and 16 males and 10 females untreated. The guinea pigs were sacrificed at 42 days by suffocation in CO2. Liver samples were immediately immersed and minced in 2% gluteraldehyde in cacadylate buffer at pH 7.4 and 4°C. After overnight fixation, samples were postfixed in 1% OsO4 in cacodylate for 1 hr at room temperature, embedded in epon, sectioned and stained with uranyl acetate and lead citrate.
