Understanding Mass Spectrometry: From Ion Generation to Spectral Interpretation

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT This tutorial provides a structured introduction to mass spectrometry (MS), with particular emphasis on electrospray ionization (ESI)–based measurements. It is intended to support researchers from chemistry and related disciplines in developing a coherent understanding of MS principles, instrumentation, and data interpretation.

Managing Spectral Intensity Variations With In‐Line Fiber‐Optic High‐Volume Noncontact Raman Probes: A Strategy Exploration

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1325-1338, August 2026.
Robust quantification in noncontact Raman sensing requires dedicated correction of working distance dependent background effects, while laser power variations are readily stabilized using internal reference signals. Chemically relevant Raman intensity can be preserved for bulk composition measurements, under variable laser power and working distance ...

Multiscale Characterization by Equibiaxial Tensile Testing and Time‐Domain 1H Solid State NMR for PTMC‐Based Networks for Tissue Growth

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Equibiaxial tensile testing combined with DMA and Time‐domain 1H${^1}H$ Solid State NMR reveals that the thermomechanical behavior of PTMC networks is strongly correlated with their internal network structure. Cross‐link density and distribution, influenced by macromer molecular weight, directly control molecular mobility, and mechanical response ...

Exploring Asymptotic Normality in Multinomial Models

Mathematical Methods in the Applied Sciences, Volume 49, Issue 12, Page 13971-13984, August 2026.
ABSTRACT Among the methods for analyzing categorical outcomes, the multinomial model offers a robust framework for examining the dependence between a multi‐category response variable and a set of explanatory variables. Its flexibility, versatility, and broad applicability across diverse fields make it a valuable tool, as it does not impose strict ...

Shape Derivatives of the Eigenvalues of the de Rham Complex for Lipschitz Deformations and Variable Coefficients: Part II

Mathematical Methods in the Applied Sciences, Volume 49, Issue 12, Page 14244-14265, August 2026.
ABSTRACT In this second part of our series of papers, we develop an abstract framework suitable for de Rham complexes that depend on a parameter belonging to an arbitrary Banach space. Our primary focus is on spectral perturbation problems and the differentiability of eigenvalues with respect to perturbations of the involved parameters. As a byproduct,
