A Bottom‐Up Design Framework for Multifunctional Lattice Metamaterials

Advanced Science, EarlyView.
This study introduces a generative AI framework for designing multifunctional lattice metamaterials. The method combines 3D Gaussian voxel generation with deep learning, enabling greater design freedom and structural performance. The optimized lattice metamaterials achieve enhanced energy absorption by 40–200% compared to conventional structures and ...

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

Advanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Machine Learning for Semi-Automated Land Parcel Plotting

The Indonesian cadastral quality improvement process, established in 2018, faces huge challenges due to its huge land area, diverse natural and social conditions, and historical mapping practices. With 15 million land parcels yet to be plotted accurately, in this work we propose a solution based on machine learning to speed up the process of plotting ...

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

Advanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...

Smart Energy–Harvesting Coating for Moisture–Droplets Based on Ionic Diodes and Transistor–Like Structures

Advanced Science, EarlyView.
A smart power‐generating coating is developed to harvest energy from both ambient humidity and impacting liquid droplets. The integrated system delivers sustained open‐circuit voltages of 0.85 V from moisture and up to 36 V from droplets. Its scalable coating architecture enables a continuous power supply for low‐power electronic devices.
