AI Article Synopsis

  • Both types of complexes, pseudo-octahedral and pseudo-square pyramidal, show structural distortions, with the ruthenium atom not perfectly aligned along the expected symmetry axis.
  • These distortions are significant because they promote or improve the π interactions between ruthenium and the iminoxolene π orbitals.
  • The specific complexes mentioned are -(Diso)RuCl and -(Diso)Ru(PPh), which highlights the impact of geometric arrangement on their electronic interactions.

Article Abstract

Both pseudo-octahedral and pseudo-square pyramidal bis-iminoxolene complexes -(Diso)RuCl and -(Diso)Ru(PPh) are structurally distorted, with the ruthenium atom slipping off the twofold axis of the idealized coordination polyhedra. These distortions take place because they allow or enhance π interactions between ruthenium and the iminoxolene π orbitals.

Lithospheric strike-slip faulting in central Tibet since 35-32 Ma and implications for the incipient Asian extrusional tectonics.

The onset age and depth of the central Tibet strike-slip faults are two still unresolved fundamental issues with regard to the Cenozoic tectonic evolution of central Tibet. Here we present a comprehensive dataset of geochronological, geochemical and structural data on recently discovered en-echelon dykes representing the incipient development of strike-slip faulting from the Lunpola basin in central Tibet. Our results provide evidence for mantle-derived, bimodal magmatism linked to lithospheric-scale strike-slip faulting at 35-32 Ma, and demonstrate that the central Tibet strike-slip faults are at least 20 Ma older than previously estimated (15-8 Ma).

This paper focuses on the theoretical and analytical modeling of a novel seismic isolator termed the Passive Friction Mechanical Metamaterial Seismic Isolator (PFSMBI) system, which is designed for seismic hazard mitigation in multi-story buildings. The PFSMBI system consists of a lattice structure composed of a series of identical small cells interconnected by layers made of viscoelastic materials. The main function of the lattice is to shift the fundamental natural frequency of the building away from the dominant frequency of earthquake excitations by creating low-frequency bandgaps (FBGs) below 20 Hz.

In this work, the high cycle fatigue behavior and tensile properties of Ti-Al-Mo-Cr-V-Nb-Zr-Sn titanium alloy at room temperature with a basketweave structure and bimodal structure were studied. The results show that the fatigue strength of the basketweave structure is higher, while the balance of strength and plasticity of the bimodal microstructure is better. However, the fatigue performance of the bimodal microstructure is unstable due to the bilinear phenomenon of the S-N curve.

Contact Dynamic Behaviors of Magnetic Hydrogel Soft Robots.

Magnetic hydrogel soft robots have shown great potential in various fields. However, their contact dynamic behaviors are complex, considering stick-slip motion at the contact interface, and lack accurate computational models to analyze them. This paper improves the numerical computational method for hydrogel materials with magneto-mechanical coupling effect, analyses the inchworm-like contact motion of the biomimetic bipedal magnetic hydrogel soft robot, and designs and optimizes the robot's structure.

Article Synopsis
  • Biomagnetic fluid dynamics (BFD) focuses on the behavior of bio-fluids, like blood, impacted by magnetic fields, which is important for medical applications such as targeted medication delivery and tumor treatment.
  • This study examines blood flow dynamics using trihybrid nanoparticles in a catheterized artery, factoring in various electromagnetic influences and propulsion mechanisms.
  • Key findings include that increasing Hall and ion-slip parameters boosts blood velocity, modifies entropy generation, and shows that modified hybrid nano-blood forms smaller, more manageable clumps compared to pure blood, with longer cilia enhancing recovery of these clumps.
