Fusion of necklace-ring patterns into vortex and fundamental solitons in dissipative media (2007)
He, Y. J., Malomed, Boris A., Wang, H. Z.
We demonstrate that necklace-shaped arrays of localized spatial beams can merge into stable fundamental or vortex solitons in a generic model of laser cavities, based on the two-dimensional complex...
The irregular nesting problem - a new approach for nofit polygon calculation (2007)
Liu, H.Y., He, Y.J., Bennell, J.A.
This paper presents a new approach for generating the nofit polygon (NFP) that is simple, intuitive and computationally efficient. The NFP has in recent years become an important tool for handling...
Cellular concentrations of glutamine synthetase in murine organs (2006)
He, Y.J., Duist, M.M. Van, Labruyere, W.T., Vermeulen, J.L.M., Dijk, P.J. Van, ...
Glutamine synthetase (GS) is the only enzyme that can synthesize glutamine, but it also functions to detoxify glutamate and ammonia. Organs with high cellular concentrations of GS appear to function...
Effects of a second phase on the tribological properties of Al2O3 and ZrO2 ceramics (1997)
He, Y.J., Winnubst, A.J.A., Schipper, D.J., Burggraaf, A.J., Verweij, H.
The tribological properties of four different materials are investigated, tetragonal zirconia (Y-ZTP), Al2O3 dispersed in Y-TZP (ADZ), ZrO2 dispersed in Al2O3 (ZTA) and Al2O3 (with 300 ppm MgO)....
Sliding wear of ZrO2-Al2O3 composite ceramics (1997)
He, Y.J., Winnubst, A.J.A., Burggraaf, A.J., Verweij, H., With De, G.
The friction and wear behaviour of two ZrO2-Al2O3 composite materials, ADZ (20 wt% Al2O3 dispersed in yttria-doped ZrO2 matrix) and ZTA (Al2O3-15 wt% ZrO2), were investigated. Sliding wear tests were...
Plasticity of nanocrystalline zirconia ceramics and composites (1997)
Winnubst, A.J.A., Boutz, M.M.R., He, Y.J., Burggraaf, A.J., Verweij, H.
The deformation strain rate of nanocrystalline Y-TZP shows an increase by a factor 4 if the grain size decreases from 200 to 100 nm. Real superplastic deformation (strain rate > 10ā4 sā1) is...
He, Y.J., Winnubst, A.J.A., Sagel-Ransijn, C.D., Burggraaf, A.J., Verweij, H.
The mechanical properties of ceramics with the compositions of 5 mol% YO1.5-TZP (ZY5) and 4 mol% YO1.5-4 mol% CeO2-TZP (ZY4Ce4) were investigated. Nanocrystalline powders of both TZPs were...
He, Y.J., Winnubst, A.J.A., Schipper, D.J., Bakker, P.M.V., Burggraaf, A.J., Verweij, H.
The friction and wear behaviour of ZrO2-Y203, ZrO2-Y203-CeO2 and ZrO2-A1203 composite ceramics against hardened steel AISI-52100 were investigated using a pin on plate configuration under...
Improvement of mechanical properties of zirconia-toughened alumina by sinter forging (1994)
He, Y.J., Winnubst, A.J.A., Verweij, H., Burggraaf, A.J.
ZTA powder with a composition of 85 wt% alumina/15 wt% zirconia was prepared by a gel precipitation method. Sinter forging was performed with this powder to enhance the mechanical properties of ZTA...
Sinter forging of zirconia toughened alumina (1994)
He, Y.J., Winnubst, A.J.A., Verweij, H., Burggraaf, A.J.
Sinter forging experiments have been carried out on powder compacts of zirconia toughened alumina (ZTA) Ceramics Alumina-15 wt% zirconia was prepared by a gel precipitation method and calcined at...
