Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

open access: yesAdvanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

On‐Water Surface Synthesis of 2D Conjugated Metal–Organic Framework Films With Controllable Layer Orientation Enabling High‐Performance Chemiresistive Sensing

open access: yesAdvanced Materials, EarlyView.
Layer orientation dictates charge transport in 2D conjugated metal–organic frameworks, yet controllable methods remain scarce. We report surfactant monolayer‐assisted on‐water synthesis of cm2‐scale Ni‐HHTP films with programmable face‐on and edge‐on orientations.

Clouds, Circulation, and Climate Sensitivity in a Radiative‐Convective Equilibrium Channel Model

open access: yesJournal of Advances in Modeling Earth Systems, 2017
Tropical cloud and circulation changes are large sources of uncertainty in future climate change. This problem owes partly to the scale separation between large‐scale tropical dynamics ( ∼104 km) and convective dynamics ( ∼1 km), which generally requires

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Operando X‐Ray Absorption Spectroscopy Reveals Dynamic Interfacial Metal–Metal Coordination Governing CO2 Reduction Selectivity in PdAg Alloys

open access: yesAdvanced Materials Interfaces, EarlyView.
Operando X‐ray absorption spectroscopy uncovers dynamic Ag–Pd coordination in PdxAg1−x electrocatalysts during CO2 reduction. Partial oxidation of Ag and composition‐dependent metal–metal bonding synergistically regulate intermediate binding, enabling ∼91% CO selectivity.

Slab Ocean Component of the Energy Exascale Earth System Model (E3SM): Development, Evaluation, and Application to Understanding Earth System Sensitivity

open access: yesJournal of Advances in Modeling Earth Systems
This work describes the implementation and evaluation of the Slab Ocean Model component of the Energy Exascale Earth System Model version 2 (E3SMv2‐SOM) and its application to understanding the climate sensitivity to ocean heat transports (OHTs) and CO2 ...

Deep time evidence for climate sensitivity increase with warming

open access: yesGeophysical Research Letters, 2016
Future global warming from anthropogenic greenhouse gas emissions will depend on climate feedbacks, the effect of which is expressed by climate sensitivity, the warming for a doubling of atmospheric CO2 content. It is not clear how feedbacks, sensitivity,

Projecting Changes in the Frequency and Magnitude of Ozone Pollution Events Under Uncertain Climate Sensitivity

open access: yesEarth's Future
Climate change is projected to worsen ozone pollution over many populated regions, with larger impacts at higher concentrations. More intense and frequent ozone episodes risk setbacks to human health and environmental policy achievements.
