Modelling the Evolution of Phases during Laser Beam Welding of Stainless Steel with Low Transformation Temperature Combining Dilatometry Study and FEM

Journal of Manufacturing and Materials Processing
In this study, the evolution of volume fractions during laser beam welding (LBW) of stainless steel, with a specific focus on incorporating the low transformation temperature (LTT) effect using the dilatometer, has been proposed. The LTT effect refers to

Coarse-to-Fine Detection of Multiple Seams for Robotic Welding [PDF]

arXiv
Efficiently detecting target weld seams while ensuring sub-millimeter accuracy has always been an important challenge in autonomous welding, which has significant application in industrial practice. Previous works mostly focused on recognizing and localizing welding seams one by one, leading to inferior efficiency in modeling the workpiece.

Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation

Advanced Science, EarlyView.
Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...

Extreme High‐Speed Laser Material Application‐Coated Carbide‐Reinforced Control Plates and Conventional Lead‐Based Plates in Axial Piston Machines

Chemical Engineering &Technology, Volume 46, Issue 1, Page 110-117, January 2023., 2023
In hydraulic axial piston pumps, conventionally leaded brass is used right against steel. In order to renounce lead and find a lead‐free alternative, high‐speed laser material deposition is employed to apply a carbide‐reinforced anti‐wear coating. Based on the experiences of prior tests, it demonstrates that this coating also works in a state‐of‐the ...

Bioinspired Mechanisms and Actuation of Soft Robotic Crawlers

Advanced Science, EarlyView.
Researchers have been developing soft materials and robotic crawlers inspired by soft‐bodied animals to mimic effective crawling in complex environments. This review explores the state‐of‐the‐art in soft crawlers, highlighting the interaction between materials, crawling mechanisms, actuation, and applications. The review concludes by providing insights

Indium‐Doping Advances High‐Performance Flexible Ag2Se Thin Films

Advanced Science, EarlyView.
A “precursor doping strategy” is employed to realize In‐doping at Ag sites in Ag2Se thin films, boosting electrical conductivity while maintaining a high Seebeck coefficient, therefore achieving a high‐power factor of ≈26.3 µW cm−1 K−2 and ZT of ≈1.

Non-triviality of welded knots and ribbon torus-knots [PDF]

arXiv
In this paper we study welded knots and their invariants. We focus on generating examples of non-trivial knotted ribbon tori as the tube of welded knots that are obtained from classical knot diagrams by welding some of the crossings. Non-triviality is shown by determining the fundamental group of the concerned welded knot.
