Superplasticity and forming of advanced materials by Tan, Ming Jen., Liew, Kim Meow., Thiruvarudchelvan, Sinnathamby.

“…Thus materials with superplastic properties can be used to form complex components in shapes that are very near the final dimension. Superplastic forming also enhances design freedom, minimizes the amount of scrap produced, and reduces the need for machining. …”

Nonthermal solid-solid phase transition in ferromagnetic iron by Azadi, S, Wark, J, Vinko, SM

“…The transition corresponds to a solid-solid BCC to FCC phase transformation and takes place at an electron temperature of 0.62 eV while the ion lattice remains near room temperature. The BCC structure initially undergoes phonon softening during the magnetic transformation, followed by a solid-solid phase transition to the FCC structure, and a subsequent hardening of phonon modes. …”

Robust and fast microwave-driven quantum logic for trapped-ion qubits by Weber, MA, Gely, MF, Hanley, RK, Harty, TP, Leu, AD, Löschnauer, CM, Nadlinger, DP, Lucas, DM

“…We implement Mølmer-Sørensen two-qubit gates on ⁴³⁢Ca⁺ hyperfine clock qubits in a cryogenic ( ≈25 K) surface trap, driven by near-field microwaves. We achieve gate durations of 154 µs [with 1.0(2)% error] and 331 µs [0.5(1)% error], which approaches the performance of typical laser-driven gates. …”

Evaluation of patient dose during multi-catheter insertion in CT-guided interstitial liver brachytherapy by Sivaprakasam, Puviya

“…Introduction: Brachytherapy is a type of cancer treatment that involves placing an encapsulated radioactive source either near or directly into the tumour. Liver brachytherapy has been practiced in institutions where multiple catheters are inserted into the liver under CT-guidance. …”

Materials beyond monolayers: The magnetic quasi-1D semiconductor CrSBr by Klein, Julian, Ross, Frances M.

“…We discuss the stability of CrSBr in air and show atomic scale structural manipulation through electron beam-driven transformations. We conclude that the stability and structural amenability of CrSBr provide opportunities for imagining devices that use bulk crystals yet exploit unique magnetic and quantum confinement effects.…”

On the study of keyhole-mode melting in selective laser melting process by Le, Kim Quy, Tang, Chao, Wong, Chee How

“…The heat source model imitates the multiple reflections of the laser beam by using the Fresnel absorption function. The model is able to simulate the fluid flow and heat transfer of keyhole-mode laser melting process, which is validated by single track experiments. …”

Effect of oblique retroreflection from a vibrating mirror on laser Doppler shift by Agusanto, Kusuma, Lau, Gih-Keong, Liu, Ting, Zhu, Chuangui

“…A laser Doppler vibrometer (LDV) fails to measure a large out-of-plane vibration of a rotating mirror when the mirror obliquely reflects the laser beam away, causing a signal loss from being detected. …”

Bandwidth analysis of waveguide grating coupler by Xiao, Zhe, Liow, Tsung-Yang, Zhang, Jing, Shum, Perry Ping, Luan, Feng

“…We observe that the bandwidth behavior is not only determined by the grating coupler intrinsic properties, but also affected by the fiber parameters such as position, beam waist and Numerical Aperture. The rigorous bandwidth formula is derived. …”

Static elastic properties of composite materials containing microspheres by Jones, GW

“…Subsequently, we analyse the buckling criterion asymptotically in the limit as the thickness ratio tends to zero by analogy with the WKB analysis of a beam on a variable-stiffness substrate. To model the shell after buckling we consider the simplified case of an embedded shell with a crack around its equator. …”

Image processing for cryogenic transmission electron microscopy of symmetry-mismatched complexes by Huiskonen, JT

“…Due to sensitivity of biological materials to the electron beam of the microscope, only relatively low electron doses can be applied during imaging. …”

Experimental and numerical study of self-locking adaptable inter connection for modular steel structures by Nadeem, Gohar, Safiee, Nor Azizi, Bakar, Nabilah Abu, Karim, Izian Abd, Mohd Nasir, Noor Azline

“…The results showed that reinforced joints sustained 80% of the limit of the rigid joint at an inter-story drift ratio of 0.04 radian and satisfied the condition for strong column weak beam joint mechanism. Non-linear Finite Element Analysis (FEA) was conducted on this adaptable connection with a parametric study to study more influences of other related parameters. …”
