Article Abstract

Determination of the heterogeneous distribution of metals in alloy/battery/catalyst and biological materials is critical to fully characterize and/or evaluate the functionality of the materials. Using synchrotron-based transmission x-ray microscopy (TXM), it is now feasible to perform nanoscale-resolution imaging over a wide X-ray energy range covering the absorption edges of many elements; combining elemental sensitive imaging with determination of sample morphology. We present an efficient and reliable methodology to perform 3D elemental sensitive imaging with excellent sample penetration (tens of microns) using hard X-ray TXM. A sample of an Al-Si piston alloy is used to demonstrate the capability of the proposed method.

Magnetic nanoparticles are gaining increasing attention as a promising alternative to gadolinium-based contrast agents in magnetic resonance imaging, primarily due to their low toxicity. In this study, we investigated the use of magnetic iron oxide nanoparticles in mouse models of intestinal inflammation to assess their potential for detecting changes in the extracellular matrix. For magnetic quantification, we employed magnetic particle spectroscopy, which offers high sensitivity and minimal interference from biological tissue.

Tetracycline (TC) is a common antibiotic with broad antibacterial activity, yet its excessive abuse will leave antibiotic residues in animal-derived food, posing some threats to human health. Therefore, developing a simple and effective technology for TC trace analysis is immediately important for food safety. Herein, the sensitive PEC aptasensor within Z-scheme heterojunction, based on Bi/BiMoO and P-doped ultrathin porous g-CN (PCN), was constructed by elemental doping strategy, hydrothermal method and surface plasmon resonance (SPR) effect.

This study aims the applicability and efficacy of a new DC water plasma method at low temperature, for the sterilization of titanium contaminated samples and its effects on the surface oxide layer and morphological structure. The plasma treatment was carried out at a temperature of 60°C, for a predefined time of 10 minutes. Water vapor was generated from distilled water and polarized at -700 V during plasma-on period.

Among the various oxidative DNA lesions, 8-hydroxy-2'-deoxyguanosine (8-OHdG) is widely recognized as a critical biomarker for assessing DNA damage and disease risk. Traditional detection methods, such as high-performance liquid chromatography (HPLC), LC-tandem mass spectrometry, and immunohistochemical techniques, provide high accuracy but suffer from limitations like time-consuming procedures, high costs, and extensive sample preparation requirements. Enzyme-linked immunosorbent assay (ELISA), a widely used and cost-effective alternative, has been increasingly explored for 8-OHdG detection.

Redox-sensitive elements figure prominently in studies of the evolution of Earth's surface redox state, including the first major rise in atmospheric O, the Paleoproterozoic Great Oxidation Event. Most Precambrian rocks endured multistage tectonothermal histories, however, adding ambiguity to interpretation of their chemistry. Here, we apply U-Th-Pb isotope geochronology to the highly oxidized ~2.
