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

“…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). …”

Two-phase immersion cooling for power dense printed circuit board converters by Ristic-Smith, A

“…A theoretical model and numerical solution method for boiling on pin fins is developed and used to design heat spreaders to increase the power dissipation per unit semiconductor area with minimal penalty on the converter volume. …”

Two-dimensional partially ionized magnetohydrodynamic turbulence by Benavides, Santiago J, Flierl, Glenn R

“…We arrive at, and numerically confirm, an expression for the energy loss due to collisions in both the weakly and strongly collisional limits, and show that, in the latter limit, the neutral fluid couples to the ions and behaves as an MHD fluid. Finally, we discuss some implications of our findings to current understanding of gas giant planet atmospheres.…”

Microbially induced calcium carbonate precipitation on surface or in the bulk of soil by Chu, Jian, Stabnikov, Viktor, Ivanov, Volodymyr

“…One of them is microbially induced carbonate precipitation (MICP), which is performed due to bacterial hydrolysis of urea in soil in the presence of calcium ions. The MICP process can be adopted to reduce the permeability and/or increase the shear strength of soil. …”

Mechanistic study and applications of lanthanide-based upconversion nanomaterials by Wei, Wei

“…The major contributions presented in this thesis are briefly summarized as follows: (1) The demonstration of cross relaxation (CR) effect as a tool for manipulating the UC color output, and an unprecedented achievement of intense 696 nm emission relying on the CR effect amongst Tm3+ ions; (2) The realization of a facile method for one-step synthesis of size- and phase-controlled water-dispersible NaYF4:Yb/Er UCNPs; (3) The development of a new type of UCNPs-based nanocomposite which may serve as potential laser protective materials.…”

Design and fabrication of a low cost desktop electrochemical 3D printer by Chen, Xiaolong, Brandon, Nigel, Childs, Peter, Wu, Billy, Liu, Xinhua

“…Electrochemical additive manufacturing (ECAM) is a relatively new technique which can create metallic components based depositing adherent layers of metal ions onto the surface of conductive substrate. In this paper, the design considerations for a meniscus confined ECAM approach is presented which demonstrates superior print speeds to equivalent works. …”

Effective control of polarity in Bi0.9La0.1FeO3 thin films by dopant-related internal bias by Wang, Yang, Chen, Weigang, Chen, Zuhuang, Rami, Naidu Chukka, Wang, Junling, Wang, John, Chen, Lang

“…The different physical origins of Ei are intimately connected with the nature of aliovalent acceptor and donor dopants of Mn and Ti ions, which is further verified by the consistent voltage offsets in the piezoelectric hysteresis loops. …”

Upconversion nanoparticles-modified aptasensors for highly sensitive mycotoxin detection for food quality and safety by Bahari, H-R, Mousavi Khaneghah, A, Eş, I

“…UCNPs consist of lanthanide ions in ceramic host, and their ladder-like energy levels at f-orbitals have unique photophysical properties, including converting low-energy photons to high-energy emissions by a series of complex processes and offering sharp, low-noise, and sensitive near-infrared to visible detection strategy to enhance the efficacy of aptasensors for novel mycotoxin detection. …”

Coexistence of harmony and freedom in the Zhuangzi by Li, Luyao

“…Zhuangzian harmony can be described as “collaborative individuals harmonize by responding to others to achieve flourishing,” while Zhuangzian freedom is defined as “an individual is free with ming (命) to pursue one’s intention.” Finally, this thesis elucidates how the tensions between harmony and freedom in Zhuangzi are resolved and how harmony and freedom can mutually enhance each other.…”
