Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Sodium-rich Particle as Evidence of Recent and Intense Micrometeoroid Bombardment on Asteroid Ryugu

The Astrophysical Journal Letters
The Hayabusa2 spacecraft returned regolith particles of the near-Earth asteroid Ryugu. We investigated two of these particles and found differences in space weathering by-products, including chemical abundance, redox state, and surface morphology.

Efficient Screening of Organic Singlet Fission Molecules Using Graph Neural Networks

Advanced Science, EarlyView.
A high‐throughput screening framework based on graph neural networks (GNNs) and multi‐level validation facilitates the identification of singlet fission (SF) candidates. By efficiently predicting excitation energies across 20 million molecules, and integrating TDDFT calculations, synthetic accessibility assessments, and GW+BSE calculations, this ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Physical and dynamic characteristics of high-inclination small bodies

Earth and Planetary Physics
Most small bodies in the solar system have low orbital inclinations, concentrated near the ecliptic plane. However, some small bodies exhibit high orbital inclinations (i > 20°) and are referred to as high-inclination small bodies.
