A Three‐Dimensional Fatigue Reliability Model Under Random Loadings

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Random loadings (RL) are prevalent in mechanical systems, yet their inherent stochasticity poses significant challenges to structural fatigue reliability assessment. In this study, a three‐dimensional fatigue reliability model is developed under RL through amplitude modulating and Fourier transformation. The non‐Gaussian RL characteristics are

Structural and Optical Modifications of Indium‐Doped Copper Oxide (CuO) Thin Films Synthesized by Chemical Bath Deposition for Enhanced Photoluminescence

open access: yesNano Select, EarlyView.
Indium (In)‐doped copper oxide (CuO) thin films are synthesized using a one‐step chemical bath deposition (CBD) method followed by annealing at 300°C. In‐doping can significantly tailor the structural, optical, and morphological properties of CuO thin films, making them promising candidates for applications in photoluminescence.

Au(III) Extraction from Water Samples Using Triazole‐Coated Novel Magnetic Adsorbents and Analysis by Inductively Coupled Plasma‐Optical Emission Spectroscopy

open access: yesChemistryOpen, EarlyView.
The synthesized magnetic nanoparticles, designated as Fe3O4@SiO2@CPTES@DAT, demonstrate effective recovery of Au(III) ions under optimized conditions at a pH of 2, utilizing 10 mg of the adsorbent, with an interaction time of 20 min. This finely tuned methodology is successfully employed to analyze various water samples regarding the recovery of Au(III)

Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).
