Advanced Science, EarlyView.We report the fast generation of biocompatible solutions of highly 13C‐hyperpolarized (≈11%) partially‐deuterated ketoisocaproate within <6 min using spin‐lock‐induced crossing and reversible exchange with parahydrogen (SLIC‐SABRE). This enables rapid detection of branched‐chain‐amino‐acid transferase 1 (BCAT1) protein expression and investigation of ...

Advanced Science, EarlyView.Benefiting from intrinsic polarization, DJ‐type 2D perovskite crystals deliver self‐powered polarization‐resolved photocurrent under weak polarized UV light via the bulk photovoltaic effect, showing a high anisotropic factor of 8. ABSTRACT Weak light detection is essential for achieving high‐performance photodetectors with minimal power consumption ...

Advanced Science, EarlyView.A chlorine‐functionalized silane modifier (CPTMS) is introduced to cooperatively regulate CO2 reduction to C2+ products on Cu‐based catalysts. Dual‐functional interface sequentially enhances CO2 activation, intermediates protonation and C─C coupling, delivering a 5‐fold increase in C2+ faradaic efficiency (FE, 75% vs.

E-portfolios and Cross-Cultural Assessment [PDF]
Sixth IEEE International Conference on Advanced Learning Technologies (ICALT'06), 2006 It is difficult to collect evidence of adequate performance if an assessor and the assessees have different linguistic and cultural backgrounds. This paper considers three entries in student portfolios where the assessor tried to understand the students and their achievement, rather than to rate it.

Intrinsic Mechanical Parameters and their Characterization in Solid‐State Lithium Batteries
Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.This review focuses on the intrinsic mechanical parameters and their associated characterization in solid‐state batteries. The physical significance of mechanics parameters is introduced with exhaustive classifications by elastic, plastic deformations and fracture in bulk, adhesion, friction at interfaces, and mechanical fatigue in cells ...

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

Low Participation and Risk Reduction Potential of Supplemental Crop Insurance in the United States
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Federally subsidized crop insurance is a cornerstone of U.S. farm risk management, yet policies with the greatest share of participation only trigger indemnities after losses exceed 15%. Supplemental insurance was introduced to cover part of this deductible, but participation remains largely unchanged.

ASCILITE’s First Virtual Conference. Proceedings ASCILITE 2020 in Armidale, 2020 This paper traces the evolution of the concept of portfolio from the Renaissance to the present day. Over time the meaning of portfolio evolved from its origins as a case for holding loose papers to other contexts such as finance, government and education. Portfolios evolved from paper to electronic, from local network to the world wide web. The decade
