Ligand‐Level Chemical Activation: Coordination with Benefits

European Journal of Inorganic Chemistry, EarlyView.
While often perceived as a liability, ligand‐based reactivity in carefully designed settings becomes a powerful synthetic tool. The key to streamlined processes overriding classical ionic reactivity is the selective electron redistribution induced by metal coordination. This enables storage of electrons and protons or incorporation of functional groups

Modeling and Power Regulation Strategy of Variable‐Speed Pumped Storage Unit With Full‐Size Converter in Pump Mode

Energy Science &Engineering, EarlyView.
A numerical model of variable‐speed pumped storage unit (VSPSU) with full‐size converter (FSC) under fast speed control strategy is established. Additionally, the correctness of the model was validated by comparing with SIMSEN simulation results and text prototype data from NARI.

3D Magnetohydrodynamic Wave Propagation and Energy Transport in a Simulated Solar Vortex

The Astrophysical Journal
Magnetic flux tubes in the presence of background rotational flows are abundant throughout the solar atmosphere and may act as conduits for MHD waves to transport energy throughout the solar atmosphere. Here we investigate the contribution from MHD waves

The Impact of Renewable and Non‐Renewable Energy on Economic Growth: Evidence From Sub‐Saharan African Countries Using Multivariate Panel Vector Autoregressive Modeling

Energy Science &Engineering, EarlyView.
This study analyzes energy consumption and economic growth across 39 Sub‐Saharan African countries using a PVAR model. Findings reveal that non‐renewable energy and labor force growth stimulate economic growth, while renewable energy does not stimulate economic growth in the short run.

Enhanced Three-minute Oscillation above a Sunspot during a Solar Flare

The Astrophysical Journal
Three-minute oscillations are a common phenomenon in the solar chromosphere above a sunspot. Oscillations can be affected by the energy release process related to solar flares. In this paper, we report on an enhanced oscillation in flare event SOL2012-07-

DFT Insight Into Physical Properties of Halide Ions Replacements in Oxo‐Selenate Halide Compounds for Photovoltaic Application

Energy Science &Engineering, EarlyView.
Using density functional theory (CASTEP, GGA–PBE), the structural, electronic, optical, and mechanical properties of YSeO₃X (X = F, Cl, Br, and I) compounds are systematically investigated. The materials have exhibited structural stability, tunable band gaps, strong optical absorption, anisotropic ductile behavior, and promising potential for ...

Poynting Flux of MHD Modes in Magnetic Solar Vortex Tubes

The Astrophysical Journal
Magnetic flux tubes in the presence of background rotational flows, known as solar vortex tubes, are abundant throughout the solar atmosphere and may act as conduits for MHD waves to transport magnetic energy to the upper solar atmosphere.
