Advantages of Alkali Metal Adduct Formation in Cyclic Ion Mobility‐Mass Spectrometry of O‐Methylated Cyclodextrin Isomers—Separation and Crossring Fragmentation

Chemistry–Methods, Volume 6, Issue 6, June 2026.
Cyclic ion mobility–tandem mass spectrometry (cIM‐MS/MS) enables rapid differentiation of O‐methylated cyclodextrin (MeCD) regioisomers. The method separates 2,3‐ and 2,6‐DIMEB (heptakis‐2,3‐ and ‐2,6‐di‐O‐methyl‐β‐cyclodextrins) and identifies them via characteristic crossring fragmentation.

Soil compaction in timber skidding in winter conditions

Croatian Journal of Forest Engineering, 2006
The research of soil compaction in timber skidding was carried out on two skid trails of uniform slope –15%and 30 %. The degree of soil compaction is shown by changes of water-air soil characteristics of the skid trail after a certain number of passes of

Mathematical Modeling and Finite Element Analysis of Residual Stress (RS) Field after Multipass Ultrasonic Surface Rolling

Advances in Materials Science and Engineering
In order to achieve the change rule of the induced residual stress (RS) field after multipass ultrasonic surface rolling (USR), a mathematical model of the induced residual stress (RS) field after multipass ultrasonic surface rolling is first established.

Microstructural, Magnetic, and Tribological Optimization of Nano‐ZrO2 Reinforced Magnesium Matrix Composites Fabricated via Powder Metallurgy

Engineering Reports, Volume 8, Issue 6, June 2026.
Magnesium–ZrO2 nanocomposites fabricated via powder metallurgy exhibited enhanced density, magnetic saturation (up to 14 emu/g), and wear resistance. Uniform nanoparticle dispersion improved bonding and reduced delamination, demonstrating strong potential for lightweight, multifunctional applications in aerospace and automotive engineering.

Roles of ER Membrane Protein Complex in Protein Biogenesis and Quality Control in the Lung and Beyond

Cell Proliferation, Volume 59, Issue 6, June 2026.
The endoplasmic reticulum membrane protein complex (EMC) is an evolutionarily conserved, multi‐subunit transmembrane protein complex crucial to membrane protein biogenesis and cellular protein quality control. This review systematically examines the structure, functions and disease‐associated regulatory mechanisms of EMC across multiple organ systems ...

Enhancing Welding Productivity and Mitigation of Distortion in Dissimilar Welding of Ferritic-Martensitic Steel and Austenitic Stainless Steel Using Robotic A-TIG Welding Process

Journal of Manufacturing and Materials Processing
The P91 martensitic steel and 304L austenitic stainless steels are two mainly used structural steels in power plants. The major problem in conventional multipass tungsten inert gas (TIG) welding of P91/304L steel is high heat input and joint distortion ...

Multipass Faraday rotators and isolators

Optics Express
Faraday isolators are usually limited to Faraday materials with strong Verdet constants. We present a method to reach the 45° polarization rotation angle needed for optical isolators with materials exhibiting a weak Faraday effect. The Faraday effect is enhanced by passing the incident radiation multiple times through the Faraday medium while the ...
