Hou, D. (author), Han, B. (author), Chen, W. (author), Liang, H. (author), Su, Q. (author), Dorenbos, P. (author), Huang, Y. (author), Gao, Z. (author), Tao, Y. (author)A series of Ce3+ doped ?-Sr2?2xCexNaxP2O7 phosphor compounds has been prepared using a high-temperature solid-state reaction technique. The luminescence properties under vacuum ultraviolet-UV and x-ray excitation were studied. Luminescence spectra reveal three UV-emitting peaks at about 310, 330, and 350 nm from which we conclude that Ce3+...journal article 2010

Han, T. (author)The wake effect from upstream wind turbines is a hot topic recently and many researches on wake modeling have been carried out in the past few years. The wake models have evolved from the simple semi-empirical approach to the dynamic meandering model using the Computational Fluid Dynamics (CFD) codes. However, some of current wake models cannot...master thesis 2011

Han, B. (author), Yang, Z. (author), Shi, X. (author), Yu, X. (author)This paper preliminarily investigates the general transport properties (i.e., water sorptivity, water permeability, and gas permeability) of carbon-nanotube/cement composites. Carboxyl multi-walled carbon nanotubes (MWNTs) are dispersed into cement mortar to fabricate the carbon nanotubes (CNTs) reinforced cement-based composites by applying...journal article 2012

Yoo, H.W. (author), Han, S. (author), Lee, Y.S. (author)We propose the receding horizon H (infinity) control (RHHC) for input-delayed systems. A new cost function for a finite horizon dynamic game problem is first introduced, which includes two terminal weighting terms parameterized by a positive definite matrix, called a terminal weighing matrix. Secondly, the RHHC is obtained from the solution to...journal article 2012

Han, S.C. (author), Riva, R.E.M. (author), Sauber, J. (author), Okal, E. (author)We quantify gravity changes after great earthquakes present within the 10 year long time series of monthly Gravity Recovery and Climate Experiment (GRACE) gravity fields. Using spherical harmonic normal-mode formulation, the respective source parameters of moment tensor and double-couple were estimated. For the 2004 Sumatra-Andaman earthquake,...journal article 2013

Zhu, G. (author), Wu, Z. (author), Zhou, Y. (author), Tang, J. (author), Dong, B. (author), Han, N. (author), Xing, F. (author)Epoxy E-51/UF resin microcapsules were prepared by traditional two-stepped in situ polymerization method and processing parameters affecting the final microcapsules shape and size were carefully studied in the aim to obtain microcapsule with ideally spherical shape and uniform size. Its found the polycarboxylate surfactant of SMA (styrene...conference paper 2013

Zhu, G. (author), Lü, L. (author), Tang, J. (author), Dong, B. (author), Han, N. (author), Xing, F. (author)For epoxy microcapsules embedded in concrete as mechanic-triggered self-healing adhesive, globular shape with uniform size is the basic requirement to ensure the solid shell broken and the liquid core released at a designed stress. In this paper, monodispersed melamineformaldehyde (MF) resin-walled epoxy E-51 microcapsules were successfully...conference paper 2013

(author)Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene...conference paper 2013
