Multi-energy X-ray imaging technology shows significant advantages in complex scenes， such as simultaneous imaging of bone and muscle defects in organisms. However, this technology has strict requirements on material selection and device design, which is a key bottleneck restricting its further development. Here, we establish the probability model of energy distribution of different energy X-rays in each layer of scintillator films, guiding the rational design of the type, thickness and stacking sequence of scintillators. Moreover, we propose a universal vitamin assisted in-situ growth method on perovskite scintillators, which provide technical support for the controllable preparation of polymer-ceramic composite scintillator films with high uniformity and radiation stability. More importantly, we have successfully realized multi-energy X-ray imaging by stacking four polymer-ceramic film, identifying materials with different densities. This research is expected to provide guidance for the rational selection of polymer host and multi-energy X-ray imaging applications.

Ginseng (Panax ginseng), long valued as the “king of medicinal plants,” faces breeding challenges due to its slow growth, limited seed production, and complex tetraploid genome. 

Grafting is a centuries-old practice that unites plants for improved resilience and yield. 

Perovskites, a class of materials known for their stellar performance in solar cells, are now making waves in the world of advanced optics. These versatile semiconductors can capture and emit light in ways that traditional materials like silicon cannot, offering a cheaper and simpler way to create cutting-edge technologies.

High-entropy doping (HED) effectively enhances microwave absorption in materials. However, achieving HED in MoS₂ without phase interference and clarifying its absorption mechanisms remain challenging. This work develops a modular doping process to incorporate multiple dopants into 1T-MoS₂. Multi-element co-doping induces lattice strain and charge redistribution, significantly improving dipole polarization loss. The optimized WVNbTaRu-MoS₂ achieves an absorption bandwidth of 7.65 GHz, over double that of undoped MoS₂. Combinatorial screening proposes 31 configurations and validates 9 variants, establishing a design framework for advanced MoS₂-based absorbers and providing new pathways for performance-oriented microwave absorber design

Researchers from DTU, EPFL and ESRF have developed a new in-operando two-dimensional X-ray imaging technique that reveals how salt formation happens in CO₂ electrolyzers during operation. By mapping salt buildup and water distribution with micrometer resolution, the team discovered that salt accumulates preferentially under gas-flow channels rather than land areas. This insight provides a critical step toward designing more stable and durable electrolyzers, paving the way for efficient large-scale CO₂ conversion into fuels and chemicals.

A research team has successfully developed a novel platform for reconfigurable nonlinear optics based on ion-doped ferroelectric nematic liquid crystals (FNLCs). This allows for precise control over the phase, polarization, and amplitude of light waves through space-varying Pancharatnam-Berry phases, opening new possibilities for advanced optical processing and quantum information technologies.
