Advanced Engineering Materials, EarlyView.We apply a foundational machine‐learning interatomic potential based on the graph atomic cluster expansion (GRACE) to simulate the commercial Ni‐based single‐crystal superalloy CMSX‐4. Hybrid Monte‐Carlo/molecular dynamics sampling resolves short‐range order in the γ phase and L12 sublattice occupancies in the γ’ phase and connects them to stacking ...

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Advanced Functional Materials, EarlyView.Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Dynamic absorber for self-excred system with distributed parameters (vibrating string)
Vietnam Journal of Mechanics, 1985 The dynamic absorber may be used to damp the self - excited vibration or the string. The friction mechanism of absorber (λ) has decisive influence on the amplitude of self-exerted vibration of the string. For the strong dynamic absorber the increasing

Self-excited vibrations of optical microresonators
Electronics Letters, 1988 Microresonators in the form of metal coated silicon dioxide strips have been driven into resonant vibration by the application of unmodulated fibre-guided light. The experiments carried out to observe this phenomenon are described, their results presented and discussed, and the implications for multiplexing microresonators sensors in fibre-optic ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
Advanced Functional Materials, EarlyView.We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Operating mechanism and optimization of dynamic absorber for a system with negative damping
Nihon Kikai Gakkai ronbunshu, 2016 The self-excited vibration, such as galloping, dry friction induced vibration and so on, often occurs in many mechanical systems and structures. For several years, the effectiveness of a dynamic absorber for self-excited vibration has been known. However,

Simplified prediction of stability limit for oil film bearing rotor systems
Nihon Kikai Gakkai ronbunshu, 2020 Oil film bearings are often used in large rotating machinery because they have large load capacity and damping coefficients. They, however, generate fluid forces and cause unstable vibrations such as oil whirl and oil whip at high rotational speed ...
