This study reveals the potential of exhaled breath analysis using PTR-MS for non-invasive lung cancer screening, identifying key VOC patterns and biomarkers.
Researchers developed CoatingDet, a publicly available dataset containing 5,416 high-resolution images of wind turbine tower coatings captured under real manufacturing conditions, with annotations for critical defects and benign surface particles. Validation with YOLOv11n and RT-DETR showed the dataset can support reproducible deep learning-based inspection while highlighting the importance of lighting conditions and class imbalance for reliable deployment.
Researchers used atomic-resolution imaging and simulations to show how twist angle alters halide-ion migration across CsPbBr3–CsPbCl3 perovskite heterostructures by changing the formation of interfacial diffusion channels. A 28° twist delayed interdiffusion, reduced the diffusion-channel ratio by more than 60%, and improved photodetector stability under accelerated thermal testing.
Researchers developed a multi-phase machine-learning framework to rapidly predict electronic band gaps and screen oxide perovskites for potential photovoltaic applications. Starting from more than half a million candidate structures, the approach progressively narrowed the search to a small group of band-gap-compatible compositions that now require higher-level computational and experimental validation.
A new purple cooling fabric developed by Chinese and Australian researchers could help people stay cooler during scorching summer days without having to resort to wearing white.
A computational preprint screened nearly 92 million compositionally complex materials to determine how elemental mixing alters neutron transport in fusion shielding. The study identified two proposed neutronic cocktail effects involving scattering, absorption, and atomic density that could guide lower-cost, more resource-efficient nuclear materials.
A decades-long collaboration between two Department of Energy Oak Ridge National Laboratory scientists is reshaping how we understand learning.
Researchers developed isosorbide-based plasticizers that made brittle poly(isosorbide carbonate) more flexible while preserving its ability to undergo ammonolysis after use. The resulting degradation products supported plant growth, including in an edible vegetable, highlighting a new way to design plastics with a useful end-of-life function.
Biology doesn’t happen at one scale. Molecular interactions unfold in milliseconds and nanometers, while disease-associated change such as in Alzheimer’s spreads across millimeters of brain tissue. Understanding complex biological systems requires scientists to watch both — ideally at the same time and with the same sample.
Researchers showed that alkaline cyanide aerosols interacting with six mineral substrates can spontaneously form mineral-organic hybrid materials, with mineral identity and reaction time shaping the resulting nitrogen-rich organic structures. The findings reveal that minerals can actively influence prebiotic molecular complexity while organic coatings can also stabilize or transform the underlying mineral phases.
