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

    Published 2023
    “…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

    Published 2013
    “…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. …”

    Tensile strength of compacted soil by Lee, Wen Yan

    Published 2018
    “…The test results were also compared to the results in Kim et al. (2012) and Fang and Chen (1972) and it is concluded that the test results in this study follows the observed trend, where the tensile strength obtained from both test is in good agreement.…”

    Preparation, antifungal potentiality, and mechanisms of action of agronanofungicides in controlling rice blast disease and enhancing yield of rice by Kutawa, Abdulaziz Bashir, Ahmad, Khairulmazmi, Hussein, Mohd Zobir, Ali, Asgar, Abdul Wahab, Mohd Aswad, Rafi, Amara, Gunasena, Mahesh Tiran, Mohd Zobir, Syazwan Afif, Berahim, Zulkarami

    Published 2024
    “…In this work, we have developed four agaronanofungicides; chitosan-hexaconazole (CHEN), chitosan-dazomet (CDEN), chitosan-hexaconazole-dazomet (CHDEN), and chitosan agronanofungicide (CEN), and evaluated their antifungal efficacy against P. oryzae. …”

    Design and analysis of passive phase shifters using controllable defected ground structures in 65nm CMOS technology for 77-81 GHz automotive radar by Wu, Jiaqi

    Published 2024
    “…Phased array radar is a low cost and promising technique to achieve high angular resolution by scanning a narrow beam in azimuth. The key enabler of a phased array radar is the phase shifter, which provides a progressive phase difference in each channel to achieve beamforming. …”

    Modeling perception errors in autonomous vehicles and their impact on behavior by Piazzoni, Andrea

    Published 2023
    “…By analyzing the data (signals), AVs respond by planning the desired trajectory and acting on the steering wheel and the throttle/brake pedals. It is trivial to observe that any error present in the perception of the surroundings will affect the decision taken, eventually leading to undesirable behavior. …”

    Solution processed transition metal oxides selective contacts for Si heterojunction solar cells by Lu, Chenjin

    Published 2021
    “…In this work, we have first prepared hole selective contacts using solution processed MoOx (s-MoOx) by spin-coating and physical evaporated MoOx (e-MoOx) by electron beam evaporator. The performance of the s-MoOx/Si HSC has been investigated and optimized, which has been demonstrated solar cell efficiency of 12.5% for s-MoOx/Si HSC that is comparable to efficiency of 13.3% for e-MoOx/Si HSC. …”

    Development of highly efficient organic and perovskite solar cells by Li, Xianqiang

    Published 2018
    “…The top Au electrodes are normally deposited by vacuum deposition methods, such as thermal evaporator and E-beam evaporator. The vacuum deposition methods increase the fabrication costs of organic solar cells and perovskite solar cells and are not compatible with roll-to-roll manufacturing process. …”

    Poisson discretizations of Wiener functionals and Malliavin operators with Wasserstein estimates by Privault, Nicolas, Yam, Phillip S. C., Zhang, Zheng

    Published 2021
    “…In addition, we derive a convergence rate of O(λ ) for the Poisson discretization of Wiener functionals by combining the multivariate Chen–Stein method with the Malliavin calculus. Our proposed sufficient condition for establishing the mentioned convergence rate involves the kernel functions in the Wiener chaos, yet we provide examples, especially the discretization of some common path dependent Wiener functionals, to which our results apply without committing the explicit computations of such kernels. …”

    An accuracy controllable and memory efficient method for computing high-quality geodesic distances on triangle meshes by Adikusuma, Yohanes Yudhi, Du, Jie, Fang, Zheng, He, Ying

    Published 2022
    “…It is worth noting that for robustness consideration, tiny windows with length less than a threshold (usually, between 10−7 and 10−6) are discarded in the implementation of the existing exact algorithms, such as the Mitchel–Mount–Papadimitriou (MMP) algorithm, the Chen–Han (CH) algorithm and their many variants. …”
