Haggerty now has some heavy machinery in place, and early next year, after the rainy season is over, he will evaluate bulk samples of the soil above the Camp Alpha pipe to see if it is worth mining.
The a-PMMA prepared in microemulsions shows higher glass transition and higher structural relaxation than those of bulk sample of the same tacticity and the same molecular weight.
Results are compared to a bulk sample of the same polystyrene using a similar experimental protocol and analysis procedure in an effort to determine the effects of nanoconfinement.
Similar to the underlying unit, bulk samples of the entire unit contain high amounts of brackish foraminifers and ostracods, but also scattered fragments of corals, mollusc shells, bryozoans and echinoderms.
A study about the presence of micro-residues is still in progress, with particular attention to the possible penetration into the bulk sample of the PEO, that is not chemically linked to the gel network.
X-ray Photoelectron Spectroscopy (XPS) analysis shows that the atomic percentage of fluorine in the near surface region of the electrospun fibers is about double the atomic percentage of fluorine found in a bulk sample of the random copolymer, as determined by elemental analysis.
The best electrical properties were obtained for a cermet-supported film, and were found close to that of a reference bulk sample of the same composition in the same conditions, whereas platinum based collectors gave very poor conductivity due to interfacial blocking effect.
Comparison of the behaviour of isolated, stretched polymer chains in their crystalline ICs with observations made on ordered, bulk samples of the same polymer are beginning to provide some measure of the contributions made by the intrinsic nature of a confined polymer chain and the pervasive, cooperative, interchain interactions which can complicate the behaviour of bulk polymer samples.
The effect of small amounts of oxygen (0.28 0.6 at.%) on the phase formation and the thermal stability of bulk samples of the Zr65Al7.5Cu17.5Ni10 alloy prepared by die casting into a copper mould has been studied by X-ray diffraction, microstructural characterization and differential scanning calorimetry.
