Force‐Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture
Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.

Axial and Biaxial Fatigue Behavior of 6061‐T651 Cold Metal Transfer Welded Joints
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT Lightweight aluminum structures in transportation systems are increasingly exposed to complex service loading, yet the fatigue performance of welded joints is still predominantly assessed using uniaxial data. In this work, the axial and biaxial fatigue behavior of 6061‐T651 aluminum alloy joints produced by cold metal transfer (CMT) welding is

Ratcheting Behavior of T225NG Titanium Alloy under Uniaxial Cyclic Stressing: Experiments and Modeling [PDF]
, 2005 In order to investigate the ratcheting behavior of T225NG alloy, a series of ratcheting tests under uniaxial long-cyclic stressing were performed. The results show that the ratcheting strain of this alloy can get into shakedown after tens (or hundreds ...

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT The present study proposes a combined approach of infrared thermography and 3D XFEM numerical models for crack process investigation in mechanical components such as gears. Over the years, fatigue crack analysis based on energy dissipations in the form of heat generated during fatigue tests has been widely reported, although mainly limited to ...

Journal of Phycology, EarlyView.Abstract The genus Paulinella represents a rare, independent case of primary endosymbiosis, providing a unique system to study the early stages of organelle evolution. Here, we expand current understanding of primary plastid endosymbiosis through the discovery and characterization of two novel photosynthetic amoebae, Paulinella marae sp. nov.

Pursuing patents for their own sake: How the investment discourse shapes patent quality and quantity
The Journal of World Intellectual Property, EarlyView.Abstract Patent systems worldwide face criticisms over declining patent quality and increasing patent quantity. While most research focuses on strengthening examination rigour, this article turns attention to relatively underexplored patenting incentives.
