Additive layer manufacture of Inconel 625 metal matrix composites, reinforcement material evaluation
, 2013 While some high performing nickel based superalloys are difficult to process through additive layer manufacturing routes, it is considered that more dilute nickel superalloy (in this case Inconel 625) based metal matrix composite may improve high ...

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.

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.

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization
Macromolecular Rapid Communications, EarlyView.This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks
Macromolecular Rapid Communications, EarlyView.Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.
