Heterogeneous catalysis at the metal surface generally involves transport of molecules through interfacial water layer to access surface, which is a rate-determining step nanoscale. In this study, taking oxygen reduction reaction on electrode in aqueous solution as an example, using accurate molecular dynamic simulations, we propose novel long-range regulation strategy midinfrared stimulation (MIRS) with frequency approximately 1,000 cm-1 applied nonthermally induce structural transition from ordered disordered state, facilitating surfaces room temperature and increasing activity 50-fold. Impressively, theoretical prediction confirmed by experimental observation significant discharge voltage increase zinc-air batteries under MIRS. This MIRS approach can be seamlessly integrated into existing strategies, offering new for accelerating heterogeneous reactions gas sensing within system.

Spatial orderliness, which is the orderly structure of molecules, differs significantly between interfacial water and bulk water. Understanding this property essential for various applications in both natural engineered environments. However, subnanometer thickness presents challenges direct rapid characterization its structural orderliness. Herein, through molecular dynamics simulations infrared spectral analysis a graphene slit pore, we reveal hyperbolic tangent relationship ordering O–H stretching information spectrum. Specifically, symmetric dominated highly ordered structure, while transition to asymmetric corresponded an increase degree disorder. Thus, behavior could serve as useful quick assessment orderliness This work provided insights into water's unique network identified vibrations' key role order, providing insight fields such nanotechnology, biology, material science.

The study of many phenomena in the terahertz (THz) frequency spectral range has emerged as a promising playground modern science and technology, with extensive applications high-speed communication, imaging, sensing, biosensing. Many THz metamaterial designs explore quantum physics embedded into classical framework exhibiting various unexpected behaviors. For spatial waves, effects inspired by include electromagnetically induced transparency (EIT), Fano resonance, bound states continuum (BICs), exceptional points (EPs) non-Hermitian systems. They facilitate realization functional metadevices applications. on-chip physics-inspired topological metamaterials, photonic analogs insulators, can ensure robust, low-loss propagation suppressed backscattering. These trends open new pathways for data transmission integrated circuits, being crucial upcoming 6G 7G wireless communication technologies. Here, we summarize underlying principles metamaterials highlight latest advances their application band, encompassing both metadevice realizations.

The heating effect of infrared pulses with varying frequencies on heavy water solutions different concentrations was investigated using non-equilibrium molecular dynamics simulations. Numerical calculations indicate that when the pulse are 39 and 72 THz, excite molecules, while temperature light molecules remains unchanged. At 53 99 molecules. Additionally, in far region (1–20 THz), both simultaneously, albeit a significantly reduced energy absorption efficiency. We also conducted comparative analysis efficiency under three distinct modes: Vibrational excitation, rotational microwave heating. results reveal vibrational excitation is seven times This conclusion holds great potential for practical applications.

ABSTRACT Polymer tribopair materials (such as UHMWPE) are widely used in complex environments like dry friction and pure water lubrication. However, with the rapid development of electromagnetic technology, how electric fields influence tribological performance UHMWPE underlying mechanisms remain unclear.
