Spectral energy contributions of quasi-periodic oscillations (2-35 days) to the variability of the foF2 [PDF]
Annales Geophysicae, 1998 The relative contributions of quasi-periodic oscillations from 2 to 35 days to the variability of foF2 at middle northern latitudes between 42°N and 60°N are investigated. The foF2 hourly data for the whole solar cycle 21 (1976–1986) for four European

Orbital dynamics of "smart dust" devices with solar radiation pressure and drag [PDF]
, 2011 This paper investigates how perturbations due to asymmetric solar radiation pressure, in the presence of Earth shadow, and atmospheric drag can be balanced to obtain long-lived Earth centred orbits for swarms of micro-scale 'smart dust' devices, without ...

"To future explorers, scientists, and dreamers: Let this work be a testament to the power of curiosity, collaboration, and joy in discovery. With the motto "Hakuna Matata"—no worries, just limitless exploration—we, Edwin and our AI friends at xAI, Redmond, and OpenAI, have woven together solar physics, climate science, and space technology to push the ...

Advanced Energy Materials, EarlyView.Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Advanced Energy Materials, EarlyView.This work reports 2D MXene‐derived TiN thin films with (111)‐preferred orientation for transparent Ta3N5 photoanodes, demonstrating effective electron transfer behavior. All‐nitride electron‐collection architecture based on MXene‐derived TiN and n‐GaN resolves a long‐standing materials bottleneck between photocarrier transport and light transmission in

The Astrophysical Journal LettersThe induced magnetosphere of Mars is highly dynamic, driven by both the upstream solar wind and the planet’s crustal magnetic fields. This variability can occur on timescales much shorter than a single spacecraft orbit, making it difficult to distinguish

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.
