A rapid and reliable approach based on SERS for quantitatively detecting RB in chili powder using a paper-based substrate was developed.
A portable and highly reproducible lab-on-capillary surface-enhanced Raman scattering (SERS) platform was developed using a specially designed homemade device for rapid on-site SERS measurement. In particular, this composed of capillary with tiny orifice, which allows an effective lossless sample extraction, resulting in high performance. The capillary-based plasmonic substrate prepared by compactly assembling Au@Ag core–shell nanorods (NRs) embedded the 4-mercaptobenzoic acid (4-MBA)...

All 12 samples high purity size uniformity assembled into densely arranged by robust liquid/liquid interface technique, their localized surface plasmon resonance...
As part of one the five major national development strategies, Yangtze River Economic Belt (YREB), including three national-level urban agglomerations (the Cheng-Yu agglomeration (CY-UA), Middle-Reach (YRMR-UA), and Delta (YRD-UA)), plays an important role in China’s economic construction. However, rapid growth past decades has caused frequent regional air pollution incidents, as indicated by high levels fine particulate matter (PM2.5). Therefore, a driving force factor analysis based on...
Abstract High-quality development plays a crucial role in China’s economic progress the new era. It represents concept of advancement and mirrors increasing aspirations populace for an improved standard living. In this context, artificial intelligence (AI) promoting sustainable cannot be overemphasized. This paper explores how AI technologies can drive transition to green, low-carbon circular economy. We have established index system measure level industry high-quality economy, which is...
