Laser‐Induced Plasma Effects on Bond Breaking in High‐Density Polyethylene Pyrolysis

open access: yesAdvanced Materials Interfaces, EarlyView.
This study introduces a novel application of Laser‐Induced Breakdown Spectroscopy (LIBS) for bond breaking in high‐density polyethylene (HDPE), an area previously unexplored in laser‐plastic interactions. For the first time, a numerical model has been developed to differentiate between photon‐induced and laser field‐induced plasma, demonstrating the ...

Direct Ink Writing of Carbon‐Based Electrofluids for Soft Electrical Component Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
This work explores the manufacturing of Electrofluids (EFs), conductive particle suspensions that flow while maintaining conductivity, for soft electrical components. Using Direct Ink Writing (DIW), patterned EFs achieve enhanced performance, including a 800% sensitivity boost in strain gauges. Through rheological studies, a printability map is created

Adaptive Elastin‐Like Hydrogel with Unidirectional and Controllable Anisotropic Actuation for Soft Robotics and Tissue Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Fiber‐reinforced elastin‐like tubular scaffolds are engineered to achieve anisotropic and reversible actuation under external stimuli. By adjusting fiber's angle, actuation behavior is finely tuned, enabling distinct actuation responses, even within different regions of the same scaffold.

Disrupting J‐Aggregation in Triazatruxene Dimers to Develop Responsive Luminescent Inks for Anti‐Counterfeiting Applications

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...

Direct Access to α,β‐Unsaturated γ‐Lactams via Palladium‐Catalysed Carbonylation of Propargylic Ureas.

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Additive carbonylations typically necessitate strong nucleophiles, such as alcohols or amines. In this study, we carbonylated a poorly nucleophilic urea, under oxidant‐free conditions. Our straightforward carbonylative strategy enables access to versatile α,β‐unsaturated γ‐lactams featuring an aminocarbonyl fragment, utilizing readily ...
