Article Abstract
Recent climate-trade policies emphasize managing carbon embedded in goods, with electricity carbon footprints as a key metric. However, the rapid energy transition complicates this evaluation. An innovative spatiotemporal model, accounting for dynamically-installed low-carbon energy infrastructure (LCPI), was developed to assess electricity decarbonization trajectories. Applying to Chinese power grid, the national and provincial electricity carbon footprints are projected to analyze the impact of LCPI deployment. By 2050, under aggressive decarbonization scenarios, the electricity carbon footprint is projected to reach 0.12 kg CO-eq/kWh-a 38.13% reduction compared to scenarios that ignore LCPI decarbonization, and a 19.18% difference when neglecting the heterogeneous carbon footprint of spatiotemporally accumulated LCPI. Meanwhile, up to 57.94% of China's electricity carbon footprint stems from historical LCPI production emissions, thereby stressing the long-lasting impact of renewable investments. Such insights support targeted policies to systematically reduce energy-related carbon footprints, providing a scalable roadmap for global sustainable energy practices.

The rapid development of industry and agriculture has led to a significant increase in the toxicity and pollution of cadmium (Cd) and lead (Pb) in soil. Consequently, soil remediation employing biochar or modified biochar has emerged as a cost-effective and environmentally sustainable approach to address the issue of heavy metal (HM) ion pollution. PEI-functionalization biochar (PBC) derived from corn straw (PBCC), wood straw (PBCW), and rice straw (PBCR) was synthesized to immobilize Cd and Pb in contaminated acidic yellow soil.

While non-destructive in-line monitoring at manufacturing sites is essential for safe distribution cycles of pharmaceuticals, efforts are still insufficient to develop analytical systems for detailed dynamic visualisation of foreign substances and material composition in target pills. Although spectroscopies, expected towards pharma testing, have faced technical challenges in in-line setups for bulky equipment housing, this work demonstrates compact dynamic photo-monitoring systems by selectively extracting informative irradiation-wavelengths from comprehensive optical references of target pills. This work develops a non-destructive in-line dynamic inspection system for pharma agent pills with carbon nanotube (CNT) photo-thermoelectric imagers and the associated ultrabroadband sub-terahertz (THz)-infrared (IR) multi-wavelength monitoring.

Developing scalable and robust deicing coatings is essential for real-world applications, yet current coatings either suffer from intrinsic fragility or low thermal conductivity, limiting sustainability and deicing effectiveness. Here, we report a scalable and durable photothermal superhydrophobic coating coupling with enhanced thermal conductivity, engineered by embedding carbon nanotubes within a perfluoroalkoxy polymer matrix. Our design achieved 97.

This study presents a renewable electricity-driven microbial electrosynthesis (MES) system integrated with biological nitrogen removal (BNR) to achieve carbon-negative wastewater treatment. The MES system converts CO₂ into acetate, which is directly utilized as an internal carbon source for denitrification. Incorporation of biochar-derived conductive materials enhanced electron transfer, increasing acetate productivity to 1.

Carbon dots (CDs) represent a new class of nontoxic and sustainable nanomaterials with increasing applications. Among them, bright and large Stokes-shift CDs are highly desirable for display and imaging, yet the emission mechanisms remain unclear. We obtained structural signatures for the recently engineered green and red CDs by ground-state femtosecond stimulated Raman spectroscopy (FSRS), then synthesized orange CDs with similar size but much higher nitrogen dopants than red CDs.
