    Conformable ultrasound breast patch for deep tissue scanning and imaging by Du, Wenya, Zhang, Lin, Suh, Emma, Lin, Dabin, Marcus, Colin, Ozkan, Lara, Ahuja, Avani, Fernandez, Sara, Shuvo, Ikra Iftekhar, Sadat, David, Liu, Weiguo, Li, Fei, Chandrakasan, Anantha P., Ozmen, Tolga, Dagdeviren, Canan

    Published 2024
    “…The in vitro studies and clinical trials reveal that the array using a piezoelectric crystal [Yb/Bi-Pb(In <jats:sub>1</jats:sub> <jats:sub>/2</jats:sub> Nb <jats:sub>1/2</jats:sub> )O <jats:sub>3</jats:sub> -Pb(Mg <jats:sub>1/</jats:sub> <jats:sub>3</jats:sub> Nb <jats:sub>2/3</jats:sub> )O <jats:sub>3</jats:sub> -PbTiO <jats:sub>3</jats:sub> ] (Yb/Bi-PIN-PMN-PT) exhibits a sufficient contrast resolution (~3 dB) and axial/lateral resolutions of 0.25/1.0 mm at 30 mm depth, allowing the observation of small cysts (~0.3 cm) in the breast. …”

    Piezoelectric single crystal based one-dimensional phased array for breast tissue imaging by Du, Wenya

    Published 2024
    “…In this thesis, I propose a conformable ultrasound breast patch (cUSBr-Patch) consisting of a one-dimensional (1D) phased array and a nature-inspired patch design, which offers large-area, deep tissue scanning and multi-angle, repeatable breast imaging while avoiding the drawbacks of conventional ultrasound imaging technologies. I used a Yb/Bi-doped PIN-PMN-PT single crystal as the active element due to its superior piezoelectric properties (d33 = 2,800 pC/N, εr = 7,000, k33 = 0.93). …”

    Additive friction stir processing by Lin, Longyi

    Published 2014
    “…The continuous dynamic recrystalisation during FSP also gave finer grains, which was further enhanced with the addition of CNTs through Zener pinning effect. The improvement in tensile strengths due to finer grains through the Hall-Petch mechanism was insufficient to compensate for the drop in Orowan strengthening. …”

    Structure and dynamics of magnetic domain walls in multi-sublattice magnetic oxides by Huang, Siying

    Published 2024
    “…We propose measuring the DW velocity with a transverse field applied to probe this field-like torque, and present experimental evidence. We investigated the DW depinning dynamics in Pt/BiYIG thin film, presenting a phase diagram of this pinning event, which proves the crucial role of minimizing the pinning effect in achieving fast DW velocity. …”

    Local-flexural interactive buckling of S690 high strength steel slender welded I-section columns: testing, modelling and design by Sun, Yao, Liang, Yating, Su, Andi, Zhao, Ou

    Published 2022
    “…A testing programme, adopting two S690 high strength steel slender welded I-sections, was firstly conducted and included initial geometric imperfection measurements and ten pin-ended column tests. The testing programme was accompanied by a numerical modelling programme, where finite element models were developed and validated against the test results and then employed to perform parametric studies to generate further numerical data over a wide range of cross-section dimensions and member effective lengths. …”

    Phenotypic, physiological, and molecular response of Loropetalum chinense var. rubrum under different light quality treatments based on leaf color changes by Zhang, Yifan, Liu, Yang, Ling, Lin, Huo, Wenwen, Li, Yang, Xu, Lu, Xiang, Lili, Yang, Yujie, Xiong, Xingyao, Zhang, Donglin, Yu, Xiaoying, Li, Yanlin

    Published 2023
    “…Moreover, we also found that the CRY-like gene, HY5-like gene, BBX-like gene, MYB-like gene, CHS-like gene, DFR-like gene, ANS-like gene, and UFGT-like gene were significantly upregulated. …”
