Xiong, W. (author), Tang, J. (author), Zhu, G. (author), Han, N. (author), Schlangen, E. (author), Dong, B. (author), Wang, X. (author), Xing, F. (author)Steel is prone to corrosion induced by chloride ions, which is a serious threat to reinforced concrete structures, especially in marine environments. In this work, we report a novel capsule-based selfrecovery system that utilizes chloride ions as a trigger. These capsules, which are functionalized via a smart response to chloride ions, are...journal article 2015

Liu, H. (author), Tang, G. (author), Imparato, D. (author), Cui, H. (author), Song, B. (author), Rizos, C. (author)Multi-GNSS networks, for example M-GEX and iGMAS, are set up and grow quickly with the development of new navigation systems and multi-GNSS receivers. It is unavoidable that GNSS signals are deteriorated by several error sources. Thus GNSS network operators, data users and receiver designers all require data quality checking (QC). However, few...conference paper 2014

Tang, J. (author)The majority of Integrated Circuit (IC) devices are encapsulated in wire-bonded plastic IC packages. Epoxy molding compound is used as the encapsulation material and gold was used as the bonding wire material. However, the increase of gold material price from 400 USD/ounce in year 2005 to 1400 USD/ounce in year 2013 results in a major cost issue...doctoral thesis 2014

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

Tang, J. (author), Gruber, D. (author), Schelen, J.B.J. (author), Funke, H.J. (author), Beenakker, C.I.M. (author)Decapsulation of a SOT23 semiconductor package with 23 um copper wire bonds is conducted with an especially designed microwave induced plasma system. It is found that a 30%-60% CF4 addition in the O2/CF4 etchant gas results in high molding compound etching rate. Si3N4 overetching which is encountered in plasma decapsulation is solved by an...journal article 2012

Xu, T. (author), Tang, Z. (author), Remis, R. (author), Leus, G. (author)OFDM suffers from inter-carrier interference (ICI) when the channel is time varying. This article seeks to quantify the amount of interference resulting from wideband OFDM channels, which are assumed to follow the multi-scale multi-lag (MSML) model. The MSML channel model results in full channel matrices both in the frequency and time domains....journal article 2012
