化石能源非能利用需求和碳排放研究 [PDF]

open access: yes, 2023
化石能源非能利用的消费量和碳排放量呈现逐年上升态势,对全球2 ℃温控目标的影响逐步显现。首先,分析了全球化石能源非能利用的基本原理、现状和趋势、关键技术,以及基于基本化工品的化石能源非能利用消费量和过程碳排放核算方法。结果表明,化石能源非能利用具有一定的固碳作用,化石原料中50%~70%的碳元素将长期存储在塑料等终端化工产品中,但是化工产品废弃物管理不善将导致这些存储的碳元素外泄。其次,设计了基准情景和低碳情景,并运用对数回归拟合法对基本化工品和化石能源非能利用的需求量进行预测。结果显示,基准情景下 ...

Emerging applications of large language models in ecology and conservation science

open access: yesConservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Reconceptualising Motivation as Material‐Semiotic Entanglements: Translanguaging in Graduate TESOL Education

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Multilingual students in Anglophone universities often operate in survival mode. While translanguaging supports learning, critical gaps remain in understanding how translanguaging pedagogies transform and sustain motivation in English‐dominant contexts.

Ultralight N‐Doped Interconnected Porous Carbon From Lignin: Synergistic Structural and Doping Engineering for High‐Performance Electromagnetic Wave Absorption

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Anthropogenic nitrogen addition interrupts seasonal connectivity and structures of plant–pollinator networks

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1878-1891, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are stressed by rapid and complex anthropogenic changes, threatening the persistence of biotic interactions and ecosystem functioning. Plant–pollinator communities, for instance, undergo structural transformations as a result of land‐use change ...

Global overview of progress in respecting the contributions of traditional knowledge in biodiversity governance

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Recognition and engagement of Indigenous Peoples and local communities (IP&LCs) and other traditional knowledge (TK) holders in formal biodiversity governance remain limited, despite their significant contribution to the conservation and sustainable use of biodiversity through their knowledge, innovations, practices, and land stewardship.

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Guanidinium‐Based Covalent Organic Frameworks via Pore Wall Regulation: Efficient Selective Palladium Recovery From Metallurgical Wastewater

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Recovering palladium (Pd) from low‐concentration metallurgical wastewater still poses significant challenges. In this study, triaminoguanidine hydrochloride was used as the key functional site, and three guanidine‐functionalized covalent organic frameworks (GCOFs) were successfully constructed by adjusting the substituents (–H, –OH, and –OCH3)

Mechanism of Selective Arsenic Purification via Reductive Vacuum Sublimation: From Oxygenated Crude Arsenic to High‐Purity Arsenic

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Arsenic presents a critical duality as both a hazardous environmental pollutant and an indispensable material for advanced semiconductor technologies. This study proposes an integrated reductive vacuum sublimation strategy, assisted by carbon and lead additives, to purify crude arsenic containing high oxygen (7.4%) and antimony (1326 mg kg−1).

生产建设项目弃土弃渣特性及资源化利用潜力评价

open access: yesShuitu Baochi Xuebao, 2020
20世纪以来,我国经济进入了蓬勃发展阶段,各类建设项目大量开展,加剧了人、地、资源之间的矛盾。生产建设项目弃土弃渣尤其是土石混合堆弃体不合理处置,不仅浪费大量的土(石)资源,还侵占大量土地,造成环境污染,甚至导致滑坡、泥石流等灾害。目前,我国正大力推行生态文明建设,土壤污染防治行动计划、无废城市建设试点工程等陆续开展,弃土弃渣资源化利用更是水土保持法的明确要求,因此开展弃土弃渣特性分析及资源化利用潜力评价具有重要的意义。以现有资料为基础,预测我国目前已有的弃土弃渣量已接近400亿t ...
