Structural Characterization and Hypoglycemic Effects of a Purified Polysaccharide From Cinnamomum cassia

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
CCP1A, a polysaccharide purified from Cinnamomum cassia with a molecular weight of approximately 8.16 kDa and rich in glucose and galacturonic acid, exerts anti‐type 2 diabetes effects through a multi‐target synergistic mechanism. On one hand, it delays intestinal glucose absorption by inhibiting the activities of α‐amylase and α‐glucosidase in the ...

Probing Metal Tip‐Induced Bond Weakening of a Reactive Alkyne Center Aligned via a Rigid Triphenylmethane‐Based Tripod on Au(111) by TERS and DFT

Journal of Raman Spectroscopy, Volume 57, Issue 6, Page 1015-1024, June 2026.
We investigate tip‐induced bond weakening of a single alkyne center immobilized and aligned upright on Au(111) using a rigid triphenylmethane‐based tripod. By varying the tip–molecule distance, we observe shifts in the ≡C–H and –C≡C– vibrational bands via ultrahigh vacuum low‐temperature tip‐enhanced Raman scattering (TERS).

Modeling and simulation of dynamic recrystallization behavior for Q890 steel plate based on plane strain compression tests

Open Physics, 2020
In view that the traditional dynamic recrystallization (DRX) model cannot effectively predict the DRX process in the hot deformation process of sheet metal, DRX behavior modeling and simulation of q890 steel plate based on the plane strain compression ...

A critical assessment of experimental investigation of dynamic recrystallization of metallic materials

Materials & Design, 2020
Dynamic recrystallization (DRX) often takes place during hot deformation of metallic materials, which then exerts significant influence on the final microstructures and mechanical properties of the formed components.

Study on Multi‐Step Deformation Mechanisms and Synergistic Regulation of Strength and Ductility in Ti‐2Al‐2.5Zr Alloy Tubes for Nuclear Power Applications

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT To overcome the strength–ductility trade‐off in fabricated Ti‐2Al‐2.5Zr alloy tubes, we systematically investigated the microstructural evolution and mechanical behavior throughout thermomechanical processing, including hot working (forging and extrusion) and cold multi‐pass rolling.

Evading Strength–Ductility Trade‐Off in Titanium Matrix Composites via High‐Critical Resolved Shear Stress Dislocation Promotion and Grain Subdivision

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The strength and ductility trade‐off in titanium matrix composites (TMCs) is a critical factor limiting their widespread application. In this study, a (TiB + TiC)/Ti–6Al–4V composite with an optimal balance between strength and ductility was engineered via multi‐directional forging.
