The Effect of Sm → Ca Substitution on Mechanical Properties of BSCCO Superconductors
(Physical Soc Republic China, 2007)
In order to investigate the effects of Sm substitution on the mechanical properties of Bi-Pb-Sr-Ca-Cu-O, Bi1.6Pb0.4Sr2Ca2-xSmxCu3Oy superconductors with x = 0.0, 0.0005, 0.001, 0.005, 0.01, 0.1, 0.5, 1.0, 1.5 were prepared ...
4-vinylpyridine and 2-hydroxyethylmethacrylate monomer mixture graft copolymerization onto poly(ethylene terephthalate) fibers using benzoyl peroxide
(Springer, 2007)
Poly(ethylene terephthalate) (PET) fibers were grafted with 4-vinyl pyridine (4-VP) and 2-hydroxyethylmethacrylate (HEMA) using benzoyl peroxide (Bz(2)O(2)) as initiator in aqueous media. PET fibers were swelled in ...
Novel phosphazene derivatives: Synthesis, anisochronism and structural investigations of mono- and ditopic spiro-crypta phosphazenes
(Elsevier, 2007)
The reactions of hexachlorocyclotriphosphazatriene, N3P3Cl6, with N2O2-donor type coronands (diaza-crown ethers) 1-3 afford novel monotopic 4-7 and ditopic 8-10 spiro-crypta phosphazenes, respectively. It has been observed ...
Repeated tissue expansions on solit-thickness skin graft in a patient with neurocutaneous syndrome
(Lippincott Williams & Wilkins, 2007)
Soft tissue expansion is a mechanical process that increases the surface area of local tissue available for reconstructive procedures. In most cases, adjacent tissue that matches the recipient site in color, texture, and ...
Applications of the zero-order reaction rate model and transition state theory on the intra-particle sintering of an alumina powder by using surface area measurements
(Elsevier Science Sa, 2007)
The cylindrical compacts with the diameter of 14mm were prepared under 32MPa of an alumina powder having agglomeration degree of 80% and maximum surface area of 81 m(2) g(-1) after calcination at 900 degrees C for 2 h. ...
