Suitability of slightly saline irrigation for alleviating drought stress in taro and yam in Tonga: Implications for climate‐resilient Pacific cropping systems

PLANTS, PEOPLE, PLANET, EarlyView.
There is an increasing risk of drought and salinisation of soil and groundwater globally, including in Pacific Island countries such as Tonga. Irrigating crops with slightly saline water, such as that produced by emerging desalination technologies, could help to alleviate droughts.

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Stabilization of Cu Species in UiO‐66 Metal–Organic Framework for CO2‐to‐Methanol: Insights From Operando X‐ray and Electron Microscopy Studies

Small, EarlyView.
This study reveals how a zirconium‐based metal–organic framework (UiO‐66) stabilizes copper species during CO2 hydrogenation to methanol. Operando X‐ray spectroscopy, electron microscopy, and theory show that zinc promotes highly dispersed copper and suppresses particle growth, while the framework dynamically responds to reaction intermediates.

A Modular Core–Shell Nanoparticle Platform for Dual‐Modal MRI–Luminescence With High Relaxivity

Small, EarlyView.
A modular core–shell nanoparticle platform is presented that combines high‐relaxivity magnetic resonance imaging (MRI) and long‐lived luminescence within a single, well‐defined architecture. Spatially controlled gadolinium(III) and terbium(III) complexes deliver reproducible dual‐modal agents with benchmark MRI performance.

Facile Sprayed and Electro‐Activated Ultra‐Low Pt Loading Catalyst for Hydrogen Evolution Reaction and PEM Water Electrolysis

Small, EarlyView.
A spray‐coating‐assisted electrochemical reduction strategy enables uniformly dispersed 2–3 nm Pt nanoparticles at an ultra‐low loading of 0.0178 mgPt cm−2 on rough gas diffusion electrode surfaces. The resulting architecture delivers exceptional hydrogen evolution activity and PEM water electrolysis performance comparable to commercial Pt/C while ...
