Stewart, S. J., Figueroa, S. J. A., Ramallo-López, J. M., Marchetti, S. G., Bengoa, J. F., Prado, R. J., ...
The non-equilibrium cation site occupancy in nanosized zinc ferrites (6-13 nm) with different degree of inversion (0.2 to 0.4) was investigated using Fe and Zn K-edge x-ray absorption spectroscopy...
Thermal dependence of the magnetization of antiferromagnetic copper(II) oxide nanoparticles (2004)
Stewart, S.J., Multigner, M., Marco, J.F., Berry, Frank, Hernando, A., Gonzalez, J.M.
We report on the temperature dependence of the magnetization of nanoparticulate CuO prepared by both precipitation and solid-state reaction methods and having average particle sizes, D, ranging from...
Marchetti, S.G., Borzi, R.A., Cabanillas, E.D., Stewart, S.J., Mercader, R.C.
We report characterizations of systems of antiferromagnetic iron oxide particles of importance in catalysis where Mossbauer spectroscopy has played an essential role. We show that signals...
Magnetic behavior of nanosized cupric oxide (2001)
Borzi, R.A., Stewart, S.J., Mercader, R.C., Punte, G., Garcia, F.
The effect of the particle size and ball-mill-induced defects on the magnetic properties of cupric oxide has been assessed by magnetic measurements. Nanoparticles with an average strain < epsilon > =...
Stewart, S. J., Borzi, R. A., Punte, G., Mercader, R. G., Garcia, F.
We have subjected powder mixtures of (0.5x)alpha -Fe2O3 and (1 - x) CuO to ball milling for a fixed period of 10 h for several x across the whole range of concentrations. No phases other than the...
Lithium insertion in compounds of the type alpha-Fe2-xTixO3 (2001)
Berry, F.J., Marco, J.F., Stewart, S.J., Widatallah, H.M.
Lithium has been chemically inserted into compounds of the type alpha -Fe2-xTixO3 (x < ca. 0.25). X-ray photoelectron spectroscopy shows the partial reduction of Fe3+ to Fe2+. Fe-57 Mossbauer...
Expression of the major outer membrane protein of Chlamydia trachomatis in Escherichia coli.
The major outer membrane protein (MOMP) of Chlamydia trachomatis was expressed in Escherichia coli. To assess whether it assembled into a conformationally correct structure at the cell surface, we...
Bacterial toxins affect early events of T lymphocyte activation.
Stewart, S J, Prpic, V, Johns, J A, Powers, F S, Graber, S E, Forbes, J T, ...
The effects of pertussis toxin and cholera toxin on early events of T lymphocyte activation were examined in the T lymphocyte cell line, Jurkat. Pertussis toxin treatment of these T cells increased...
Willman, C L, Stewart, C C, Griffith, J K, Stewart, S J, Tomasi, T B
To study the expression of src-related protooncogenes during the development of myeloid cells and the regulation of these genes by the colony-stimulating factors that control myelopoiesis, normal...
Zhang, Y X, Stewart, S J, Caldwell, H D
Monoclonal antibodies exhibiting Chlamydia trachomatis serovar specificity (serovar A, B-Ba, or C) and serogroup specificity (B, intermediate, or C serogroup) were produced and characterized. These...
Stewart, S J, Cunningham, G R, Strupp, J A, House, F S, Kelley, L L, Henderson, G S, ...
A number of cellular signaling systems are called into play by interaction of the T lymphocyte antigen receptor/CD3 complex with its cognate antigen. Well-described signaling systems include...
Stewart, S J, Prpic, V, Powers, F S, Bocckino, S B, Isaacks, R E, Exton, J H
Antibodies directed against the T-cell antigen receptor-T3 complex mimic antigen and lead to cellular changes consistent with activation. When cells of the human T-cell line Jurkat were stimulated...
Link, M P, Stewart, S J, Warnke, R A, Levy, R
We have examined the expression of the Leu-4 (T3) antigen on the cell surface and in the cytoplasm of blast cells from 23 patients with T cell acute lymphoblastic leukemia and T cell lymphoblastic...
