The effects of the thermal environment about the wire were investigated at low rates of sweep, of the order of 10 kgauss/min or 16 amp/min. It has been found that at these rates of sweep, the results obtained were almost independent of the thermal environment of the wire. Measurements were carried out with parts of the wire surface exposed directly to liquid helium, with the wire (1) firmly cemented against a holder of large thermal capacity, (2) cemented in frozen glycerin, (3) cemented in Duco cement, and (4) unsupported and un-eoated in contact with liquid helium across the whole area of the hairpin tip. 

Their fifth and sixth reprecipitations they finished on Thursday, March 6. From 1.2 kilograms of UNH they had now separated less than a millionth of a gram of pure Np239 mixed with sufficient carrier to stain a miniature platinum dish that measured two-thirds of an inch across and half an inch deep. When they had dried this speck of matter God had not welcomed at the Creation they simply snipped oflf the sides of the platinum dish, covered the sample with a protective layer of Duco Cement, glued the dish to a piece of cardboard labeled Sample A and set it aside until it decayed completely to 94 . 

The formula for the conducting adhesive is as follows 43g Duco cement (DuPont S/N 6241), 23 g silver power (Handy and Harman Silflake 135), 125 cc acetone. 

Lucite and Plexiglas (polymethyl methacrylate as marketed by du Pont and by Rohm and Haas, respectively) and polystyrene are transparent thermoplastic materials. Their machinability is fairly good but somewhat limited by their thermoplasticity. They are strongly attacked by solvents such as acetone. They can be cemented with solvents alone (trichloroethylene) or with such cements as Duco. Over long periods cracks may develop at points of strain, and discoloration may result from prolonged exposure to strong light. 

X-rav Diffraction. X-ray diffraction patterns of metallized tubules were recorded on a Rigaku DMAXB X-ray diffractometer in the theta-two theta mode using Cu-K radiation. A small amount of an acetone suspension of metal coated tubules was dried on a silicon wafer with a small amount of adhesive cement (Duco) and the diffraction pattern was recorded in the theta-two theta mode. From the width at half height of the (111) peak, the average grain size of the nickel microcrystallites was determined using the Debye-Scherrer law. ... 

Other pSOFC joining techniques that have been considered include the use of high-temperature cements and sealants formed by reaction bonding. Although commercial ceramic adhesives such as Duco and Sauereisen cements have been...
