Powder‐to‐Film Conversion of Nickel Single‐Atom Catalysts into Binder‐Free and Resistant Electrodes

open access: yesAdvanced Materials Interfaces, EarlyView.
A reproducible strategy is reported for fabricating standalone thin‐film electrodes composed of CNx‐supported Ni single‐atom catalysts. The resulting binder‐free electrodes exhibit robust stability, enhanced charge transfer, and superior electrochemical performance, offering scalable opportunities for applications in electrochemistry. ABSTRACT Although

A Tale of Two Time Scales: Determining Integrated Volatility with Noisy High Frequency Data [PDF]

open access: yes
It is a common practice in finance to estimate volatility from the sum of frequently-sampled squared returns. However market microstructure poses challenges to this estimation approach, as evidenced by recent empirical studies in finance.

Strong Lateral Confinement of Hydrophilic Silica Nanoparticles on Mg‐Al Layered Double Hydroxides Nanoflakes for Enhanced Thermal Properties

open access: yesAdvanced Materials Interfaces, EarlyView.
A nanostructured, naturally flame‐retardant, and non‐toxic inorganic composite is introduced, which is laterally associated with silica nanoparticles to induce the restacking of the LDH lamella structure, thereby serving as an efficient thermal insulator.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

open access: yesAdvanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Derivatives on volatility: some simple solutions based on observables [PDF]

open access: yes
Proposals to introduce derivatives whose payouts are explicitly linked to the volatility of an underlying asset have been around for some time. In response to these proposals, a few papers have tried to develop valuation formulae for volatility ...

Mass Spectrometric Investigation of the Influence of Water Vapour and Oxygen on Gas‐Phase Reactions of Aluminium Acetylacetonate

open access: yesAdvanced Materials Interfaces, EarlyView.
The gas‐phase decomposition of Al(acac)3 is investigated under inert, oxygen, and water‐containing conditions. Water is found to promote selective ligand removal and suppress hydrocarbon formation, while oxygen induces faster, less selective decomposition pathways.
