Orientation-selective microwave heating of laser-graphitized diamond at 2.45 GHz
Massimiliano Zamengo, Meguya Ryu, Haoran Mu +6
Pristine diamond couples negligibly to a 2.45 GHz field. We show that femtosecond-laser inscription of a buried graphitic (sp2) architecture makes a 4 x 4 x 2 mm^3 N-doped (100 ppm…
Heating of black-Si by microwaves at 2.45 GHz: effect of nano-needle orientation
Massimiliano Zamengo, Haoran Mu, Hsin-Hui Huang +4
Silicon, which is highly reflective and has negligible absorption at the microwave 2.45 GHz range, can be heated when it is turned into black-Si with a surface texture of nano-need…
Oxidation of Tantalum Nano-Film by Microwave Exposure
Massimiliano Zamengo, Lina Grineviciute, Hsin-Hui Huang +4
Oxidation and ablation of 200 nm tantalum films were carried out by three routes: (i) femtosecond (fs-)laser direct write, (ii) high-temperature annealing (HTA) in a tube furnace,…
Diamond membranes: platform for photonic and opto-mechanical applications
Hsin-Hui Huang, Gediminas Seniutinas, Haoran Mu +8
Diamond 1 - 10 micrometers thick membranes are platform for photonic, quantum and opto-mechanic devices with applications across UV-IR spectral ranges. IR characterization of diamo…
Olivine annealed up to 1500 C: changes traced by polarised IR reflectance and magnetization
Daniel Smith, Donatas Narbutis, Hsin-Hui Huang +14
Spectral analysis at the infrared (IR) spectral range is introduced with assignment of synthetic red-green-blue (RGB) colours defined by adjustable wavelength and bandwidth. The RG…
Nanoscale Surface Analysis of High Entropy Alloy
Hsin-Hui Huang, Meguya Ryu, Yoshiaki Nishijima +10
Nanoscale surface analysis of 1 micrometer thick high entropy alloys (HEAs) was carried out using nano-IR for hyperspectral imaging and single point spectroscopy in the 700-1700 1/…
High Entropy Alloy under Shock Compression: Optical-Pump X-Ray-Probe
Hsin Hui Huang, Meguya Ryu, Shuji Kamegaki +23
High entropy alloys (HEAs) are multi-principal-element alloys designed for tailorable mechanical performance and have been attracting significant engineering interest, yet their fu…
Structure orientation determined in transmission and reflection: q-plate
Hsin-Hui Huang, Meguya Ryu, Shuji Kamegaki +9
Determination of orientation in the imaged sample/scene has a large application potential when the anisotropy of properties is analysed, usually, under a linearly polarised illumin…
Mid infrared imaging of mass transport in polymer electrolyte membranes of an operating microfluidic water electrolyzer
Stéphane Chevalier, Meguya Ryu, Jean-Christophe Batsale +1
This study investigates water transport in a polymer electrolyte membrane (PEM) electrolyzer using operando infrared spectroscopic imaging. By testing different H2SO4 anolyte conce…
Anisotropy analysis of bamboo and tooth using 4-angle polarization micro-spectroscopy
Meguya Ryu, Hsin-Hui Huang, Jitraporn Vongsvivut +6
To investigate the anisotropic properties of biomaterials, two distinct classes are considered: polymer-based (e.g., cellulose in plants) and crystalline-based (e.g., enamel in tee…
Bridging Spectroscopy and Advanced Molecular Orientation Analysis with New 4+ Angle Polarization Toolbox in Quasar
Callum Gassner, Jitraporn Vongsvivut, Meguya Ryu +10
Anisotropy plays a critical role in governing the mechanical, thermal, electrical, magnetic, and optical properties of materials, influencing their behavior across diverse applicat…
Interferometric microscale measurement of refractive index at VIS and IR wavelengths
Meguya Ryu, Simonas Varapnickas, Darius Gailevicius +6
Determination of refractive index of micro-disks of a calcinated (C in air) photo-resist SZ2080 was carried out using transmission and reflection spectros…
Determination of Stokes vector from a single image acquisition
Shuji Kamegaki, Meguya Ryu, Soon Hock Ng +4
Four Stokes parameters (1852) define the polarisation state of light. Measured changes of the Stokes vector of light traversing an inhomogeneous sample are linked to the local anis…
