Pulsed Laser Synthesis of Carbon Nanostructures from Organic Molecular Liquids: Structure, Kinetics and Photophysical Properties

Advanced Science, EarlyView.
The non‐focused nanosecond pulsed laser irradiation of aromatic liquids produces amorphous carbon nanodots (CNDs) or curved‐graphene quantum dots (c‐GQDs) by surface‐catalyzed 0‐order reactions under kinetic control. C hybridization partially changes from sp2 to sp3. O‐based groups passivate the surface.

Magnetic‐Driven Viscous Mechanisms in Ultra‐Soft Magnetorheological Elastomers Offer History‐Dependent Actuation with Reprogrammability Options

Advanced Science, EarlyView.
Magnetically induced microstructural rearrangements in ultra‐soft magnetorheological elastomers modulate their viscoelasticity, enabling programmable mechanical memory. Magnetic actuation induces long‐term viscous relaxation and double‐bumping stress responses due to particle chain formation.

Me‐4PACz Functionalized MXene for Halide Perovskite Solar Cells

Advanced Science, EarlyView.
Functionalized Ti₃C₂ MXene nanoneedles with Me‐4PACz employed at the interface between perovskite and Spiro‐OMeTAD, improve charge extraction, energy alignment, and surface hydrophobicity. Devices show boosted PCE (21.5%) and operational stability (T88 = 1000 h, ISOS‐L‐1), highlighting MXene:Me‐4PACz as a powerful strategy for simultaneously improving ...

Solution‐Shearing of Highly Smooth Ion‐Gel Thin Films: Facilitating the Deposition of Organic Semiconductors for Ion‐Gated Organic Field Effect Transistors

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...
