Taming Flexibility: Synergistic Pore and Polarity Engineering in a MOF for High‐Efficiency Xe/Kr Separation

Advanced Science, EarlyView.
Through a mixed‐ligand strategy that precisely regulates pore size and framework polarity, the Xe adsorption behavior is transformed from flexible to near‐rigid. ZIF‐7‐Cl(20) achieves sensitive recognition, efficient capture, and high selectivity for Xe, enabling high‐efficiency separation from Xe/Kr mixtures.

An Energy-Based Approach for Fatigue Life Estimation of Welded Joints without Residual Stress through Thermal-Graphic Measurement

Applied Sciences, 2019
The traditional methodologies for fatigue life assessment of welded joints strongly depend on geometries and surface characteristics, as well as time. In this paper, an energy-based approach, independent of structures though thermal-graphic measurement ...

Influence of high-energy shot peening on the microstructure and mechanical properties of Ti–6Al–4V welded joints

Materials Research Express, 2020
In this study, Ti–6Al–4V welded joints were subjected to a high-energy shot peening (HESP) treatment. The structural characteristics of the Ti–6Al–4V welded joints were investigated by optical microscopy (OM) and x-ray diffraction (XRD).

Influence of the Welding Process on the Hardness of the Welded Joint

Revista de metalurgia, 2004
Laser and TIG welding processes are suitable for welding of thin sheets. Welding of heat-treatable steels causes substantial increase of the hardness in the welded joint area. Laser and TIG welding differ regarding the power density and heat input into the material.

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype

Advanced Intelligent Systems, EarlyView.
A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Tips and Tricks for Hardware Removal and Allograft Fixation After a Failed Latarjet Procedure

Arthroscopy Techniques, EarlyView.
Abstract Although relatively rare, recurrent anterior shoulder instability requiring revision surgery after a failed Latarjet procedure can result in complications such as graft malposition, graft osteolysis, broken hardware and/or infection. Revision surgery after a failed Latarjet is a challenge due to a combination of technical factors such as ...
