Ultra Short Pulse Laser Welding of Glass to Metal in the Low Fluence Regime
Laser &Photonics Reviews, EarlyView.Ultrashortpulse laser welding enables precise joining of glass and metal with minimal thermal damage. We introduce the TwoThresholds Criteria to identify suitable laser parameters by combining the nonlinearabsorption threshold in glass with the metalmodification fluence threshold.

Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit
Materials and Corrosion, EarlyView.The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with

Materials and Corrosion, EarlyView.The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.

Macromolecular Rapid Communications, EarlyView.Liquid crystal elastomer (LCE) filaments are fabricated through extrusion with in‐process UV curing, enabling controlled flow alignment and network locking of mesogens. The resulting structure responds to thermal or optical stimuli, inducing molecular reorientation and macroscopic contraction.
