Molecular Dynamics Simulation in the Mechanism Exploration Research of Environmental Remediation: Current Status and Challenges

Environmental pollution severely impacts ecosystems, human health, and socio-economic development, necessitating efficient removal and detoxification of pollutants. Traditional trial-and-error approaches are inadequate for developing high-performance environmental materials and remediation technologies. Molecular dynamics (MD) simulations have emerged as essential tools for elucidating pollutant removal and toxicity mechanisms at the atomic-molecular level. This review summarizes core computational methods of MD simulations, including force fields, ensemble settings, and enhanced sampling techniques. It then discusses applications in novel adsorbent materials, bioremediation (enzyme catalysis), membrane separation, and membrane fouling, highlighting how MD reveals microscopic interaction mechanisms. Current limitations, such as force field accuracy, timescale constraints, and system size, are critically assessed. Future integration with artificial intelligence (AI) and machine learning is explored for accelerating simulations, improving force field parameterization, and enabling high-throughput screening. The review aims to promote mechanism-based design and diversified development of environmental pollution control materials and remediation technologies.

Defect and Crystal Field Engineering Enables High Efficiency and Anti-Thermal Quenching in Cr3+ Doped Rigid Garnet Phosphors for Multifunctional Optoelectronics

Near-infrared (NIR) phosphors with high quantum efficiency (QE) and thermal robustness are critical for phosphor-converted light-emitting diodes (pc-LEDs). Here, a Cr3+-activated Lu2BaAl4SiO12 (LBASO) garnet phosphor is engineered via chemical unit cosubstitution of [Ba2+-Si4+] for [Lu3+-Al3+] in Lu3Al5O12 (LuAG), inducing a strong crystal field that yields NIR emission at 705 nm. The optimized LBASO:0.07Cr3+ exhibits an internal quantum efficiency (IQE) of 84.82% and external quantum efficiency (EQE) of 46.02%. Notably, it demonstrates anti-thermal quenching (ATQ) with 126.03% of its initial intensity at 498 K under 442 nm excitation, attributed to a wide band gap, weak electron-phonon coupling, defect trap energy levels, high structural rigidity, and optimized electron population distribution. A NIR pc-LED fabricated with this phosphor achieves an output power of 134.99 mW and photoelectric conversion efficiency of 11.4% at 100 mA drive current. These results underscore the potential of LBASO:Cr3+ for applications in plant lighting, night vision, and nondestructive analysis.
