Precipitation of large crystals/agglomerates of spinel and their accumulation in the pour spout riser of a Joule-heated ceramic melter during idling can plug the melter and prevent pouring of molten glass into canisters. Thus, there is a need to understand the effects of spinel-forming components, temperature, and time on the growth of crystals in connection with an accumulation rate. In our st...

BixSb1-x)2Te3 (.5 ≤ x ≤ .7) polycrystalline samples were synthesized using a combination of melting and powder metallurgy techniques. The samples were hot pressed in graphite dies and cut perpendicular and parallel to the pressing direction. Samples were examined by microprobe analysis to determine their atomic composition. The thermoelectric properties were measured at room temperature in both...

This work investigated the adsorption of 2,4-dichlorophenoxyacetic acid (2,4-D) on various activated carbon cloths (ACCs) prepared from a phenolic resin commercially known as Novoloid. Experimental adsorption equilibrium data were obtained in a batch adsorber. The effects of temperature and pH on the adsorption capacity of ACCs were studied and it was found that the adsorption capacity decrease...

We have investigated the near liquidus phase relations of a primitive absarokite from the Mascota region in Western Mexico. Sample M. 102 was chosen because it has high MgO contents, a high Mg# and Fo90 olivine phenocrysts, indicating it is primitive mantle melt. Highpressure experiments on a synthetic analogue of the absarokite composition with a H20 content of either -1.7 wt% or -5.1 wt% were...

ganic C (SOC). Soils of the southeastern United States of America, particularly sandy Coastal Plain soils, have Soil organic matter (SOM) is of primary importance for maintaining inherently low SOC contents (typically below 1%, Hunt soil productivity, and agricultural management practices may signifiet al., 1982). Consequently, small changes in the SOM cantly influence SOM chemical properties. ...
