Researchers from East China Normal University have developed a vehicle-mounted mid-infrared dual-comb spectroscopy system that reliably detects methane leaks in real time at speeds up to 100 km/h. Published in Optics Express, the compact, vibration-resistant device operates without pre-deployed field hardware and achieves near-laboratory-grade precision (66 ppb for methane). By mapping 2D gas diffusion patterns alongside GPS data, the system offers a scalable tool to identify hidden greenhouse gas leaks and guide targeted repairs.

Food‑medicine homologous polysaccharides are widely known for safety and immunomodulatory effects. A new Opinion article offers an updated perspective: these glycans are not merely bioactive ingredients, but multi‑role biological materials that can act as immune signaling molecules, structural scaffolds and drug‑delivery carriers simultaneously. The authors analyze key bottlenecks and propose cross‑disciplinary strategies to advance them from empirical natural products to rationally‑designed precision immune‑intervention tools.

For thousands of years, the concept of food‑medicine homology (FMH) has guided health practice in Traditional Chinese Medicine, yet its underlying molecular mechanisms remain poorly defined. A new opinion piece puts forward the “5R Principle” framework and outlines how multiple chemistry disciplines can transform empirical ancient wisdom into precise, testable molecular‑level health strategies, bridging traditional experience with modern quantitative science.

Chinese medicinal cuisine, known as yao shan, has long‑standing cultural roots in Traditional Chinese Medicine. A multi‑disciplinary Perspective puts forward a falsifiable systems‑science framework for its modernisation. Rather than simply adding modern technologies to old practices, the work converts traditional TCM concepts into testable scientific hypotheses, establishes causal research chains, separates quality‑safety‑efficacy evidence, and delivers a four‑stage roadmap to advance reproducible, internationally comparable yao‑shan research and application.

Polycrystalline ferroelectric ceramics can provide strong piezoelectric and electro-optic responses, but pores, grain boundaries and ferroelectric domains scatter light, making transparency difficult to combine with functionality. A new review systematically connects these optical-loss mechanisms with densification, grain and domain engineering, phase tuning and defect control in lead-based PMN–PT and lead-free KNN ceramics. It evaluates five coupled functions—piezoelectricity, electro-optic modulation, energy storage, photoluminescence and photochromism—and distinguishes ceramic devices from single-crystal, thin-film and glass benchmarks. The authors outline a roadmap based on machine learning, texture engineering, high-Curie-temperature design, additive manufacturing and system-level integration.

With the Railway and Infrastructure Laboratory, TU Graz is expanding its railway research facilities to include a state-of-the-art testing laboratory. Here, the entire track system can be tested under realistic conditions.

A new manufacturing method could help move the production of nanoscale sensors from specialized fabrication facilities to conventional semiconductor manufacturing plants.
