Feng, Shuo (author), Jiang, Tao (author), Chen, Wei (author), Fan, Xuejun (author), Zhang, Kouchi (author), Fan, Jiajie (author)As a core packaging material of light color conversion, phosphor/silicone composite plays an indispensable role in light emitting diode (LED) packaging. At present, commercial LED packages mainly use blue LED chips to stimulate Yttrium Aluminum Garnet (YAG) yellow phosphor to reach a white color. However, (Ca,Sr)AlSiN 3 :Eu 2+ (CSASN) red...conference paper 2022

Cao, Yixing (author), Chen, Wei (author), Du, Yunjia (author), Qi, Gaojin (author), Santos, Thebano (author), Zhang, Kouchi (author), Fan, J. (author)YAG: Ce3+ phosphor/silicone composites are widely used in solid-state lighting as a light converter to achieve white lighting. However, because of high thermal resistance and low thermal stability, the luminous performance of YAG: Ce3+ phosphor/silicone composite deteriorates rapidly when excited by high-power-density blue-laser. To explore...journal article 2022

Zhang, Qinglong (author), Han, Rui (author), Xin, Gaofeng (author), Liu, Chi Harold (author), Wang, Guoren (author), Chen, Lydia Y. (author)Deep neural networks (DNNs) have been showing significant success in various anomaly detection applications such as smart surveillance and industrial quality control. It is increasingly important to detect anomalies directly on edge devices, because of high responsiveness requirements and tight latency constraints. The accuracy of DNN-based...journal article 2022

(author), Alù, Andrea (author), Kuipers, L. (author)Near-field scanning optical microscopy is a powerful technique for imaging below the diffraction limit, which has been extensively used in biomedical imaging and nanophotonics. However, when the electromagnetic fields under measurement are strongly confined, they can be heavily perturbed by the presence of the near-field probe itself. Here,...journal article 2022

Chen, Y. (author), Toosumran, Nuttapon (author), Chehab, Noura (author), Spanjers, H. (author), Copuroglu, Oguzhan (author)This paper proposes the use of desalination brine as a setting and hydration activator in set-on-demand 3D concrete printing. A series of tests were conducted to investigate the effect of adding different concentrations of desalination brine on stiffness evolution and early-age hydration of Portland cement mortars (PC mixtures) and limestone...journal article 2022

Chen, N. (author), Buchholz, Florian (author), Tune, Daniel D. (author), Isabella, O. (author), Mihailetchi, Valentin D. (author)The edge recombination losses of crystalline silicon solar cells become significant when they are cut into smaller pieces to be assembled into modules. With the interdigitated pattern of doped p and n regions on the rear side, the interdigitated back contact (IBC) solar cells can be cut through different doped regions. In this study, the...journal article 2022

Chen, Y. (author)Chinese cities have experienced rapid urbanisation and attracted massive investment in the central city through urban redevelopment. Developing less favourable urban areas such as former industrial sites along the waterfront is less attractive for investment as these areas usually need to deal with poor environments and complicated land...journal article 2022

Zhang, Y. (author), Zhang, Shizhe (author), Chen, Y. (author), Copuroglu, Oguzhan (author)In this paper, both synthetic slag and commercial slag covering the common composition range were employed to estimate the correlation between slag chemistry and reactivity through hydraulicity and dissolution tests. It was found that slag reactivity was favorably affected by increasing Al<sub>2</sub>O<sub>3</sub> and MgO contents, while the...journal article 2022
