Amplified Sensitivity in SERS Detection of L1CAM With Silver Plasmonic Mesoporous Silica Capsules on an Imprinted Films

Advanced Materials Interfaces, EarlyView.
This study presents core‐shell Au‐Ag NPs and a novel molecularly imprinted polymer (MIP)‐based material targeting L1CAM. Thionine is used as a monomer to create the MIP on a carbon screen‐printed electrode. Functionalized Au‐AgNCs with Raman reporter 4‐mercaptobenzoic acid and anti‐L1CAM enable selective detection via surface‐enhanced Raman scattering ...

Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite

Advanced Materials Technologies, EarlyView.
Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication

Local Type Inference for Context-Free Session Types [PDF]

EPTCS 420, 2025, pp. 1-11
We address the problem of local type inference for a language based on System F with context-free session types. We present an algorithm that leverages the bidirectional type checking approach to propagate type information, enabling first class polymorphism while addressing the intricacies brought about by the sequential composition operator and type ...

Dual‐Wavelength Vat Photopolymerization With Dissolvable, Recyclable Support Structures

Advanced Materials Technologies, EarlyView.
Selective solubility vat photopolymerization (SSVP) uses a single resin to produce dissolvable thermoplastics and insoluble thermosets in a single 3D print. Wavelength‐selective curing and thermal post‐processing provide 3D spatial control over dissolution kinetics, enabling dissolvable support structures and programmable dissolution profiles.

Coupled Optical Response of Armchair Graphene Nanoribbons and Single Wall Carbon Nanotube Hybrid Structures

Advanced Optical Materials, EarlyView.
A strong interaction between the five‐armchair graphene nanoribbons (GNRs) and the encapsulating single‐walled carbon nanotubes is identified. A reduction of the bandgap of the hybrid structure as well as additional proof for the single H‐terminations of the GNRs are confirmed through a combination of optical absorbance spectroscopy and density ...
