The MgB2 bulks were prepared by high energy milling of Mg and B powder. The correlations among milling times, microstructure and superconducting properties were investigated in MgB2 bulks. Samples...
Wu, Y. F., Yan, G., Li, J. S., Feng, Y., Chen, S. K., Tang, H. P., ...
The powder-in-tube MgB2 wires were prepared by high energy milling of Mg and B powder. The powder was not mechanically alloyed for 2h short milling time. However, the MgB2 grains in wires are very...

We succeeded in the synthesis of high-Jc MgB2 bulks via high energy ball-milling of elemental Mg and B powder at ambient temperatures. Alternatively to longtime mechanical alloying technique, the...
Strong Pinning Enhancement in MgB2 Using Very Small Dy2O3 Additions (2006)
Chen, S. K., Wei, M., MacManus-Driscoll, J. L.
0.5 to 5.0 wt.% Dy2O3 was in-situ reacted with Mg + B to form pinned MgB2. While Tc remained largely unchanged, Jc was strongly enhanced. The best sample (only 0.5 wt.% Dy2O3) had a Jc of 6.5 x 10^5...

Strong influence of boron precursor powder on the critical current density of MgB2 (2005)
Chen, S. K., Yates, K. A., Blamire, M. G., MacManus-Driscoll, J. L.
The influence of the nature of the boron precursor on the superconducting properties of polycrystalline MgB2 was studied. Critical current densities for the MgB2 made from high purity amorphous boron...
Improved Current Densities in MgB2 By Liquid-Assisted Sintering (2005)
Chen, S. K., Lockman, Z., Wei, M., Glowacki, B. A., MacManus-Driscoll, J. L.
Polycrystalline MgB2 samples with GaN additions were prepared by reaction of Mg, B, and GaN powders. The presence of Ga leads to a low melting eutectic phase which allowed liquid phase sintering and...

Branch Recovery with Compiler-Assisted Multiple Instruction Retry, (1998)
Alewine, N. J., Chen, S. K., Li, C. C., Fuchs, W. K., Hwu, W. M.
In processing systems where rapid recovery from transient faults is important, schemes for multiple instruction rollback recovery may be appropriate. Multiple instruction retry has been implemented...
Aspects of Erosional Wear Behavior During Tumbling of BaTiO3 Dielectric Ceramics. (1998)
Chen, S. K., Chang, C. P., Liu, H. S.
Erosional wear by tumbling is a necessary step in shaping and surface finishing before the application of metallic end-termination in the manufacture of millimeter-sized, brick-shaped ceramic...
The comparative ability of self-organizing neural networks to define cluster structure
Chen, S. K., Mangiameli, P., West, D.
The ability to determine clusters or similarity in large, multivariate data sets is critical to many business decisions. Unfortunately, current cluster algorithms are sensitive to dispersion that...
