Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

Journal of Raman Spectroscopy, EarlyView.
In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

Jewelled Byzantine and Medieval Reliquaries of the True Cross: Peridots and Other Gemstones in Material and Symbolic Perspective

Journal of Raman Spectroscopy, EarlyView.
An interdisciplinary in situ study of jewelled reliquaries of the True Cross integrates gemmology and portable analytical techniques, revealing new evidence on the identification and symbolic role of peridots and other gemstones. ABSTRACT Jewelled crosses containing relics of the True Cross occupy a central position in the devotional, artistic and ...

Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures

Journal of Raman Spectroscopy, EarlyView.
A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO2$$ {}_2 $$ and the v2$$ {v}_2 $$ mode of CH4$$ {}_4 $$. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH4$$ {}_4 $$ and CO2$$ {}_2 $$ spectra in a diffusion flame ...

Common‐Mode Rejection Shifted‐Excitation Raman Difference Spectroscopy (CMR‐SERDS) Preserves Broad Structure Predictive of Soil Organic Carbon

Journal of Raman Spectroscopy, EarlyView.
Common‐mode rejection (CMR) is introduced as a physics‐motivated preprocessing method for shifted excitation Raman difference spectroscopy (SERDS) that removes the shared background of paired measurements while preserving the noncommon excitation‐dependent component. Applied to more than 900 North American soil samples, CMR improves soil organic carbon

Analytical Approaches to Address Challenges in the Analysis of Cannabinoids in Vascular Matrices Using Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Phytocannabinoids are bioactive metabolites derived from the Cannabis sativa plant. They have garnered attention due to their recreational uses and therapeutic potential. Although various analytical strategies have been employed for their analysis, mass spectrometry (MS) coupled to chromatographic separation is superior due to its sensitivity ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

Mass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

Mass Spectrometry Reviews, EarlyView.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is
