Volatile loss following cooling and accretion of the Moon revealed by chromium isotopes [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance With the exception of volatile elements, which are strongly depleted and isotopically fractionated, the Moon has chemical and isotopic signatures that are indistinguishable from Earth’s mantle.

Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

open access: yesAdvanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Cu2O/Cu Chiral Catalysts for Highly Selective Solar‐Assisted CO2‐to‐CO Electroreduction

open access: yesAdvanced Functional Materials, EarlyView.
To address the poor target‐product selectivity of the eCO2RR, breakthrough approaches based on the chiral‐induced spin selectivity phenomenon enhance the Faradaic efficiency (FE) for target hydrocarbons, such as CO. To induce this spin polarization strategy in Cu2O/Cu catalysts, it is proposed using amine‐based intermediate organic molecules with ...

Methods for exomoon characterisation: combining transit photometry and the Rossiter-McLaughlin effect

open access: yes, 2010
It has been suggested that moons around transiting exoplanets may cause observable signal in transit photometry or in the Rossiter-McLaughlin (RM) effect.

Intrinsically‐Stretchable and Patternable Quantum Dot Color Conversion Layers for Stretchable Displays in Robotic Skin and Wearable Electronics

open access: yesAdvanced Materials, EarlyView.
Intrinsically‐stretchable, heavy‐metal‐free quantum dot color conversion layers are produced via a versatile crosslinking strategy. The color conversion layers exhibit minimal backlight leakage under mechanical strain, support high‐resolution patterning, and integrate seamlessly with micro‐light‐emitting diodes. Their incorporation in haptic‐responsive
