Low-cost architecture for iron-based coated conductors.

The design of iron-based coated conductors (IBS-CC) with a simplified architecture is possible thanks to the material properties that allow for milder requirements on the template crystalline quality. With respect to the state-of-the-art multilayered layout, it is possible to use a single buffer layer that remains necessary for protection and to promote the oriented growth of the superconducting film. In this work, Fe(Se,Te) films are grown via pulsed laser deposition (PLD) on commercial tapes using a single, chemically deposited, CeO-based buffer layer, and interesting properties are obtained.

High-performance Fe(Se,Te) films on chemical CeO-based buffer layers.

The fabrication of a Fe-based coated conductor (CC) becomes possible when Fe(Se,Te) is grown as an epitaxial film on a metallic oriented substrate. Thanks to the material's low structural anisotropy, less strict requirements on the template microstructure allow for the design of a simplified CC architecture with respect to the REBCO multi-layered layout. This design, though, still requires a buffer layer to promote the oriented growth of the superconducting film and avoid diffusion from the metallic template.

Evaluating the Conservation State of Naturally Aged Paper with Raman and Luminescence Spectral Mapping: Toward a Non-Destructive Diagnostic Protocol.

Micro-Raman and luminescence spectroscopy were combined with morphological analysis to study the conservation state of differently degraded paper samples, dated from 1873 to 2021. The aim of the work reported in this paper was to obtain ageing markers based on variations of Raman and fluorescence spectral features. Raman and luminescence spectra were acquired by scanning non-printed areas of books, and Raman and fluorescence maps were built by contrasting spectral parameters point by point, obtaining a micron-scale space resolved imaging of the degradation pattern.

Cells Selectively Captured by Phages and Identified by Surface Enhanced Raman Spectroscopy Technique.

In this work, the results on the detection and identification of () cells by using surface-enhanced Raman spectroscopy (SERS) are presented. has been chosen as a harmless surrogate of the pathogen () responsible for the deadly Anthrax disease, because of their genetic similarities. Drops of 200 μL of suspensions, with concentrations 10 CFU/mL, 10 CFU/mL, 10 CFU/mL, were deposited on a SERS chip and sampled after water evaporation.

Surface-enhanced Raman spectroscopy characterisation of functionalised multi-walled carbon nanotubes.

Multi-walled nanotube (MWNT) functionalisation was investigated by surface-enhanced Raman spectroscopy (SERS). The MWNTs were deposited as dilute dispersions on SERS-active substrates. We used nano-structured gold surfaces with various morphologies for our measurements.
