On shear adhesion of adhesive fibrils by Linghu, Changhong, Du, Zihao, Sun, Yi, Chen, Weiqiu, Hsia, K. Jimmy

“…Our model reveals that, depending on the fibrillar aspect ratio, the adhesive fibril exhibits three distinct deformation regimes: thin film shearing, thick block shearing, and slender beam bending. The important parameters governing the shear adhesion of the lap shear system are the aspect ratio of fibrils, elastic moduli of the fibrils and substrates, while the Poisson's ratio of fibrils has no noticeable effect. …”

Squeezing the Quantum Noise of LIGO below the Standard Quantum Limit by Jia, Wenxuan

“…The SQL applies when using uncorrelated photons or coherent light to measure the object, such as a laser beam. However, introducing quantum correlations through squeezed light, a technique called squeezing (Chapter 2), can circumvent this limit. …”

Surface plasmon resonance (SPR) enhanced biosensors by Zhang, Jinling

“…The fabrication steps of the arrays were composed of electron-beam lithography and nano-imprint lithography. In comparison with the PAuNH array, the AuNH array offered higher field enhancement for fluorescence when only LSP was excited. …”

SPP/LSP coupled hybrid mode directed multi-functional surface-enhanced Raman system by Du, Luping

“…In the experiment, SPPs are excited by a tightly-focused radially polarized beam and interact with the nanospheres to generate the plasmon-hybrid-mode, exactly according to the second configuration aforementioned. …”

Hybrid lasers and modulator on silicon in the near- and mid-infrared region by Hu, Xiaonan

“…The lateral grating can be fabricated by CMOS-compatible inline lithography, which avoids the use of expensive and time-consuming electron beam lithography. The device works at room temperature with the single-side-suppression-ratio (SMSR) of 20 dB and the threshold current density is 1.54 kA/cm2. …”

Developments in THz Polaritonics: Towards Integrated Nonlinear THz Spectroscopy by Sung, Eric Rueyhao

“…The optical pump light is focused onto the bevel, after which it refracts and becomes confined within the waveguide by total internal reflection. This allows the pump beam to repeatedly drive the generated THz field during its multiple back-and-forth traversals within the LN slab. …”

Compositionally graded alloys fabricated using the laser powder bed fusion technique by Wei, Siyuan

“…In this study, among the several available AM processes, the LPBF technique is selected to fabricate compositionally graded alloys, as it has higher spatial resolution and lower cost, compared to directed energy deposition (DED) and electron beam powder bed fusion (EBPBF). With three different LPBF setups and four alloy systems examined in this study, the following objectives are achieved: (i) screening out, from a large range of compositions, the alloys that are amenable to LPBF, (ii) examining the effects of the LPBF characteristics, e.g., rapid cooling rate, on the micro-/meso-structure and properties of the fabricated parts with varying chemical compositions, and (iii) evaluating the fabrication methods in terms of types of achieved gradation (stepwise or smooth), efficiency, and level of chemical segregation. …”

Synthesis and characterization of Cu-Chalcogenide nanocrystals for potential applications in low-cost solar cells by Ahmadi, Mahshid

“…Since the opto-electrical properties of the NCs are highly dependent on the composition and crystal structure, X-ray diffraction, selected area electron diffraction, convergent beam electron diffraction and Raman spectroscopy were used to determine their crystal structure. …”

Enhancing tensile and fatigue properties of additively manufactured alloys by post-processing heat treatment by Radhakrishnan, Jayaraj

“…Amongst the different AM techniques, laser beam-powder bed fusion (LB-PBF) is the most abundantly investigated process due to its deep market penetration as well as the vast number of LB-PBF machine manufacturers. …”

A combined numerical and experimental approach to investigations of body-freedom flutter on flying wings by Ang, Elijah Hao Wei

“…The structural dynamics are modelled using an Euler-Bernoulli beam which is tightly coupled with the rigid-body motions of the flying wing, and subsequently discretised using the finite-element method. …”
