Ultrafast Light‐Driven Electronic and Structural Changes in LaFeO3 Perovskites Probed by Femtosecond X‐Ray Absorption Spectroscopy

open access: yesAdvanced Materials, EarlyView.
Femtosecond X‐ray absorption spectroscopy (fs‐XAS) at PAL‐XFEL captures ultrafast electronic and structural dynamics in epitaxial LaFeO3 thin films. Combined with DFT and multiplet calculations, the study reveals photoinduced ligand‐to‐metal charge transfer, followed by polaron formation and reduced oxygen 2p‐iron 3d hybridization, explaining key ...

Fast Prototyping and Ex Vivo Evaluation of Dissolvable Millineedle Patches Made by Solvent Casting from CO2 Laser Ablated Elastomer Molds

open access: yesAdvanced Materials Interfaces, EarlyView.
CO2 laser ablation, a fast, inexpensive, and reproducible method, is used to create flexible elastomer molds with millimeter‐long cavities for the fabrication of dissolvable polymer needles. Made from PVP, these milli‐needles achieve ≈560 µm penetration into porcine skin, demonstrating their potential for effective transdermal drug delivery.

ENVIRONMENTAL AND NATURAL RESOURCE POLICY AND THE OPTIMAL DISPERSION OF PROPERTY RIGHTS [PDF]

open access: yes
Environmental policies generally address problems associated with ill-defined property rights. Our framework describes property rights "regimes" as functions of the degree of consolidation of rights to an asset and of the parties holding those rights ...

Leveraging Grain Boundary Effects for Nanostructured Electrode Layers in Symmetric Solid Oxide Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Nanocrystalline thin‐films of lanthanum chromite exhibit extraordinary properties of fast oxygen kinetics. These properties are due to the peculiar chemistry of grain boundaries and can be harnessed for fabricating symmetric electrochemical devices with self‐healing properties. Abstract While grain boundary engineering is attracting great interest as a

High‐Resolution and Surface‐Sensitive Tip‐Enhanced Raman Spectroscopy Characterization of Strained‐Silicon Devices through Cleanroom‐Compatible Plasmonic Probes

open access: yesAdvanced Materials Interfaces, EarlyView.
This paper demonstrates how Tip‐Enhanced Raman Spectroscopy (TERS) can detect diverse levels of strain in a SiGe‐Si structure in less than 20 nm of depth with lateral resolution under 100 nm. The measures are performed with a TiN‐coated probe, which secures a remarkable enhancement of the optical signal, while being chemically stable to allow TERS to ...
