Ultrasound‐Triggered Gelation for Restoring Biomechanical Properties of Degenerated Functional Spinal Units

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces an innovative approach to treating intervertebral disc degeneration using ultrasound‐triggered in situ hydrogel formation. Proof‐of‐concept experiments using optimized biomaterial and ultrasound parameters demonstrate partial restoration of biomechanical function and successful integration into degenerated disc tissue, offering a ...

A New Secure Encryption Scheme Based on Group Factorization Problem

open access: yesIEEE Access, 2019
As special types of factorization of finite groups, logarithmic signatures and covers have been used as the main components of cryptographic keys for secret key cryptosystems such as $PGM$ and public key cryptosystems like $MST_{1}$ , $MST_{2 ...

A New Family of Ternary Intermetallic Compounds with Dualistic Atomic Ordering – The ZIP Phases

open access: yesAdvanced Materials, EarlyView.
The ZIP phases are ternary intermetallic compounds with dualistic atomic ordering, i.e., they exhibit one face‐centered cubic (fcc; space group Fd3¯$\bar 3$m) variant and one hexagonal (space group P63/mmc) variant. The ZIP phases in the Nb‐Si‐Ni system are the Nb3SiNi2 (fcc) and Ni3SiNb2 (hexagonal) ternary IMCs, crystal structure schematics of which ...

Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz

open access: yesAdvanced Materials, EarlyView.
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Successive Orthorhombic Distortions in Kagome Metals by Molecular Orbital Formation

open access: yesAdvanced Materials, EarlyView.
Orthorhombic distortions in kagome metals break the symmetry required for exotic charge order. Synchrotron X‐ray diffraction of NdRu3Si2 reveals successive orthorhombic transitions driven by molecular orbital formation between kagome layers. The frustrated kagome lattice hosts degenerate patterns of kagome dimers whose short‐range correlations produce ...

Solvability of certain exponential Lebesgue-Nagell equations 𝑥 2 + 𝑝 𝑚 = 𝑦 [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2023
In this article, we first investigate the exponential Lebesgue-Nagell equation as shown in the title. Eventually, we can establish a necessary and sufficient criterion for having an integer solution to such an equation under the conditions that 𝑝 ≡ 3 ...
