Wide Temperature Zero Thermal Expansion in Al Matrix Composites with High Thermal Conductivity

Advanced Science, EarlyView.
Strain engineering strategy is implemented on the negative thermal expansion (NTE) phase Zn1.6Mg0.4P2O7 within composites, where Al matrix‐induced compressive strain drives uniform polyhedral and unit cell evolution, thereby enabling broad and consistent thermal compensation efficacy and obtaining good thermal performance.

Tailored D‐π Conjugation Boosts Piezocatalytic CO2 Reduction in a Platinum(II)‐Acetylide Framework

Advanced Science, EarlyView.
The highly conjugated metalII‐acetylide framework demonstrates efficient ultrasound‐driven conversion of CO2 to CO. The piezoelectric field generated by ultrasound facilitates electron transfer from the tetraphenylene π‐column to the MII‐bis(acetylide) moiety, enabling CO2 activation. Compared to PdII‐ and NiII‐based analogues, the stronger d–π orbital

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates

Advanced Science, EarlyView.
Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...

Radiation Resilient Synthetic Antiferromagnets‐Based Neuromorphic Device for Sea Surface Temperature Reconstruction

Advanced Science, EarlyView.
By leveraging strong antiferromagnetic coupling, radiation‐tolerant synthetic antiferromagnetic synaptic devices are developed. Their intrinsic nonlinearity emulates neuronal activation, while linear and symmetric conductance modulation mimics synaptic plasticity.

Resolution, physics and atmosphere–ocean interaction – How do they influence climate model representation of Euro-Atlantic atmospheric blocking? [PDF]

Tellus A: Dynamic Meteorology and Oceanography, 2017
Atmospheric blocking events are known to locally explain a large part of climate variability. However, despite their relevance, many current climate models still struggle to represent the observed blocking statistics. In this study, simulations of the global climate model EC-Earth are analysed with respect to atmospheric blocking. Seventeen simulations

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

A Compact Hollow Fiber Electrode Assembly Architecture for Continuous Electrochemical Marine Carbon Dioxide Removal

Advanced Energy Materials, EarlyView.
A coaxial, membrane‐integrated hollow fiber electrode assembly (HFEA) is developed for continuous marine carbon mineralization. By utilizing a sub‐millimeter inter‐electrode gap, the HFEA minimizes Ohmic losses, achieving 50% energy reduction and over 85% DIC removal.

Integrated Bipolar Membrane Electrodialysis and Electrolysis for CO2 Capture and Conversion

Advanced Energy Materials, EarlyView.
This work demonstrates an integrated BMEED platform that couples CO2 capture and conversion within a single modular system. By combining BMED with CO2E, high‐purity CO is produced while avoiding intermediate stripping, excessive capital and O&M costs, and external gas feeds.

Vendor Types, Attendance, Experience and Sales 2019–2021: Evidence From Five Rural Oregon Farmers Markets

Agribusiness, EarlyView.
ABSTRACT Farmers markets provide a direct‐to‐consumer marketing path for farmers and small businesses, facilitating customer discovery and product refinement. This paper explores farmers markets as a business incubator, with a focus on beginning vendors and resilience to a shock, namely, COVID‐19 market restrictions.
