How the Arrangement of Platinum Atoms on Ruthenium Nanoparticles Improves Hydrogen Evolution Activity

open access: yesAdvanced Materials, EarlyView.
A synthetic strategy for the formation of Pt islands and their transformation into Pt atomic strings on Ru nanoparticle surfaces is presented. The thermodynamically favored configuration of Pt strings on Ru catalyst is demonstrated to catalyze HER via the faster Volmer–Tafel pathway with a significantly improved intrinsic activity, owing to the well ...

A Universal Method for Achieving Ultra‐Low Contact Resistances in Organic Electrochemical Transistors

open access: yesAdvanced Materials Interfaces, EarlyView.
The incorporation of LiTFSI as a dopant in OECT's channel decreases contact resistances by a factor of ≈2 and ≈40, both in p‐type and n‐type polymers. It reaches an unprecedented width‐normalized contact resistance value as low as 1 Ohm.cm in p(g2T‐T).

Progress in Flexible Perovskite Solar Cells: Paving the Way for Scalable Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
Perovskite solar cells (PSCs) are well positioned for a successful market uptake. This is due to an unprecedented improvement of their efficiency and stability since the first report in 2009. In this review paper, the building blocks for the scalable manufacturing and future commercialization of flexible PSCs and their pathway to impact will be ...

Bandgap Tuning of β‐(AlxGa1‐x)2O3 Nanosheets via Liquid Metal Interface Engineering

open access: yesAdvanced Optical Materials, EarlyView.
Ultrathin β‐(AlxGa1‐x)2O3 nanosheets with controlled composition are synthesized via low‐temperature squeeze‐printing of Al─Ga liquid alloys. Aluminium preferentially migrates to the surface of the liquid alloy, forming Al‐rich oxide layers with tunable bandgaps up to 6.4 eV. This compositionally precise approach enables the fabrication of 2D ultrawide‐

Direct Growth of Rectangular 2D Layered Metal‐Halide Perovskite Microcrystal Photonic Cavities on Functional Substrates

open access: yesAdvanced Optical Materials, EarlyView.
A simple and scalable method to fabricate 2D layered metal halide microcrystals with rectangular shape, extremely flat surfaces, and submicron thickness is presented. The growth occurs in evaporating droplets on planar substrates, which enables the fabrication of the microcrystals directly on functional surfaces. The microcrystals demonstrate excellent
