The Limits of Depoliticized Water–Energy Diplomacy: Insights From the UAE–Israel–Jordan Water‐for‐Energy Deal

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT This paper examines the rise and collapse of the 2021 United Arab Emirates (UAE)–Israel–Jordan Water‐for‐Energy Deal, a landmark initiative that sought to exchange Jordanian solar energy for Israeli desalinated water. Presented as a breakthrough in regional cooperation and environmental peacebuilding, the agreement was brokered under the ...

Contrasting light demands determine the coordination of plants' non‐structural carbohydrates and economic strategy over the range of solar spectral composition

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 534-552, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Non‐structural carbohydrates (NSC) are critical mediators of plant adaptation to fluctuating light environments. They are tightly coordinated with plant economic strategy, that is, leaf economics spectrum (LES) and root economics spectrum (RES).

Boosting TiO2 Photocatalytic H2O2 Production via S, N‐Codoped Lignin‐Derived Carbon Dots: Quantifying the Enhancement Role

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Carbon dots (CDs) have emerged as promising modifiers for boosting the photocatalytic H2O2 production, yet their precise role remains to be quantitatively elucidated. Herein, S, N‐codoped lignin‐derived carbon dots (SN‐LCDs) and lignin‐derived carbon dots (LCDs) were synthesized and employed to modify TiO2.

The Rhetoric of Disenchantment: Ghost Belief and Secular Critique in Early Twentieth‐Century China

open access: yesCognitive Science, Volume 50, Issue 1, January 2026.
Abstract This study presents the first large‐scale empirical analysis of how ghosts and spirits were debated during China's early twentieth‐century secular transformation. Using a novel dataset of over 2000 digitized texts—including newspapers, periodicals, and essays from 1890 to 1949—we combine close reading, AI‐assisted annotation, and statistical ...

太阳能电池的光学管理基本理念

open access: yes四川大学学报. 自然科学版, 2015
活性层吸光能力和载流子传输能力之间的折衷是制约太阳能电池效率提升和成本降低的重要因素之一.特别是随着太阳能电池的薄膜化发展趋势,活性层吸光能力不足所导致的光学损失显得越来越重要.而光学管理技术能够有目的地调控入射光谱,在太阳能电池中获得可控的光场传输和能量分布,在实现光吸收增强的同时还保持了活性层优秀的电学传输性能,正是克服这一折衷的有效工具.本文从光线光学、传统波动光学和纳米光子学的视角详细阐述了典型陷光结构的光约束和增强机制,展望了光学管理技术的发展趋势.
