All-Solid-State Sodium-Ion Batteries with Organic Quinone Cathodes and Na₃PS₄ Electrolyte for Grid-Scale Storage
Grid-scale energy storage demands batteries that are safe, low-cost, and made from earth-abundant elements. We report an all-solid-state sodium-ion battery (ASS-SIB) using anthraquinone-grafted carbon nanotube... -

Photocatalytic Degradation of Microplastics by Heterostructured TiO₂/g-C₃N₄ Nanotubes under Solar Irradiation
Microplastic pollution in aquatic environments has emerged as a global crisis, with an estimated 14 million tonnes entering the oceans annually. Current removal methods (filtration, coagulation) capture particles but... -

Urban Heat Island Mitigation through Optimized Green-Blue Infrastructure Networks: A Multi-City Digital Twin Study
Urban heat islands (UHIs) increase city temperatures by 2-8°C relative to surrounding rural areas, exacerbating heat-related mortality, energy consumption, and air pollution. We present a multi-physics digital twin... -

Calcium Looping with Biomass Co-Firing for Carbon-Negative Cement Production: Pilot Plant Demonstration
Cement manufacturing accounts for 8% of global CO₂ emissions, with roughly 60% arising from limestone calcination (process emissions) that cannot be eliminated by fuel switching alone. We demonstrate a 1 MWth calcium... -
