Abstract This paper presents a standalone predictive model for Atomic Oxygen (AO), Coronal Mass Ejections (CMEs) and other space-environment parameters. The prediction is based on the numerical method of Holt–Winter’s triple smooth exponential forecasting atmospheric constituents. Solar cycle 25 likely to show about same activity as 23. corresponding AO-flux–solar-activity correlation coefficie...

In this work, without introducing mass-in-mass units or inertial amplification mechanisms, we show that two Bragg atomic chains can form an acoustic metamaterial possesses different types of bandgaps other than ones, including local resonance and amplification-like bandgaps. Specifically, by coupling masses one monatomic chain to the same a diatomic triatomic chain, hybrid be generated further ...

Using molecular dynamics, the effect of an atomic mass difference on a localized phonon mode in SiGe alloys was investigated. Phonon dispersion relations revealed that change causes optical and acoustic modes to shift frequency. The results indicate local is sensitive both Si Ge changes; reducing shifts higher frequencies, increasing lower frequencies. Furthermore, suggest originates from Si–Ge...

] that a novel inorganic hydride compound KHI which comprised a high binding energy hydride ion was synthesized by reaction of atomic hydrogen with potassium metal and potassium iodide. Potassium iodo hydride was identified by time of flight secondary ion mass spectroscopy, X-ray photoelectron spectroscopy, 1 H and 39 K nuclear magnetic resonance spectroscopy, Fourier transform infrared spectro...
