Development of high-speed photoelasticity for visualization of shear stress field in pressure-sensitive gel

Nihon Kikai Gakkai ronbunshu
Present study aims to develop a high-speed photoelasticity with a high-speed polarization camera for evaluating the stress loading on a pressure-sensitive gel by fingertip movements. Prior to this, normal stress loading and phase retardation field on the

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Photoelastic force measurements in granular materials

, 2016
Photoelastic techniques are used to make both qualitative and quantitative measurements of the forces within idealized granular materials. The method is based on placing a birefringent granular material between a pair of polarizing filters, so that each ...

Ultrafast Laser‐Induced Interatomic Forces in Magnetostrictive Metals

Advanced Science, EarlyView.
This study reports ultrafast changes in the interatomic forces generated by femtosecond laser excitation in magnetostrictive FeGa thin films. This ultrafast process manifests as an optical birefringence signal lasting ≈400 fs. Using a pump‐probe system, the femtosecond evolution of this nonequilibrium interatomic interaction is visualized, providing ...

Fe‐Based Nanocrystalline Magnetic Shielding Cylinder with Subfemtotesla‐Level Magnetic Noise

Advanced Science, EarlyView.
Shields with low magnetic noise are achieved by integrating Fe‐based nanocrystalline magnetic shielding cylinders into shielding systems based on μ‐metal. Benefiting from high permeability and low loss factor, Fe‐based nanocrystalline magnetic shielding cylinders effectively suppress magnetic noise. Notably, the magnetic shielding cylinder with the ten‐

Basal Plane Activation of SnS2 Thin‐Film by Fluorine Doping for Selective Solar‐Driven CO2 Reduction With Enhanced Quantum Efficiency

Advanced Science, EarlyView.
The synergistic effect of fluorine doping and sulfur vacancies boosts the activity of the active sites without active‐site modulation, leading to enhanced CO2 photoreduction efficiency and a selectivity switch from CH4 to CO on tin disulfide continuous thin films. ABSTRACT Photocatalytic conversion of CO2 into value‐added fuels offers a viable approach
