Leaf C:P ratio as a universal indicator of photosynthesis in subtropical woody species: Stoichiometric thresholds and metabolic trade‐offs

open access: yesFunctional Ecology, Volume 40, Issue 7, Page 2332-2344, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.

Land use overrides climatic controls on soil organic nitrogen transformations: Contrasting responsiveness between forest and cropland ecosystems

open access: yesFunctional Ecology, Volume 40, Issue 7, Page 2128-2142, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil organic nitrogen (SON) transformation is critical for global nutrient cycling and ecosystem productivity, yet how its responsiveness to climate change differs across diverse land use types remains poorly resolved.

Upcycling of Waste Polyethylene Terephthalate Plastics to Fabricate Cobalt–Nickel Metal–Organic Frameworks and Their Phosphides for Efficient Oxygen Evolution Reaction

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves

Root exudates mediate microorganisms to improve rhizosphere nutrient availability and crop productivity under straw mulching and slow‐release nitrogen fertilizer

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.

种还分离模式下玉米秸秆还田对土壤磷有效性及其有机磷形态的影响

open access: yesShuitu Baochi Xuebao, 2017
采用尼龙网袋法对种还分离模式下的玉米秸秆还田进行田间原位模拟,比较不同秸秆还田量在不同还田深度下对土壤全磷、速效磷和不同形态有机磷的影响。试验设置4个水平秸秆添加比例R0(0%)、R1(0.44%)、R2(0.88%)、R3(1.32%)和3个不同还田深度0—15,15—30,30—45 cm交叉处理。结果表明,秸杆还田1 a后,各土层中土壤全磷含量随秸秆还田量的增加均无显著改变;在0—15 cm土层中,与R0相比,R1、R2、R3处理下的土壤速效磷分别增加了27.0%,49.3%,64.1%,在15 ...

Phosphotungstic Acid Modulated PNIPAM/P(AA‐co‐AM) Bilayer Hydrogels With Programmable Thermo‐Responsive Kinetics and Enhanced Toughness

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Thermo‐responsive hydrogels based on poly(N‐isopropylacrylamide) (PNIPAM) are promising candidates for soft actuation, yet their practical applications are often constrained by sluggish thermo‐responsive kinetics and insufficient mechanical robustness.

有机磷在调节土壤磷素保持与释放过程中的作用

open access: yes, 2013
以巢湖沿岸土壤和沉积物为对象,分析了速效磷、藻类可利用性磷、有机磷含量和碱性磷酸酶活性的空间变化格局,并测定了磷吸附参数。结果表明,土壤有机磷含量差异显著,以草地最高,而速效磷和藻类可利用性磷含量无明显差异;酶活性及速效磷含量与有机磷含量呈显著正相关,土壤对正磷酸根的吸附量与土壤中有机磷含量呈正相关;湖泊沉积物中有机磷含量与周边土壤中有机磷含量显著正相关。因此 ...

光催化氧化分光法检测水中DOP和DON

open access: yesGongye shui chuli, 2007
通过TiO2光催化氧化法,在60min内降解AMP、ADP、ATP有机磷标准化合物、尿素和EDTA有机氮标准化合物,并与国标方法消化结果进行了对比。光催化氧化法消化自然水体中有机磷和有机氮的效果可以达到并超过国标方法;有机磷化合物被降解成PO43-,有机氮化合物先被氧化分解成NH4+,再进一步被氧化成NO3-,降解产物便于进行定量测定,并设计出在线分析装置,从而使光催化氧化法替代传统方法用于分析自然水体中的溶解有机磷(DOP)和溶解有机氮(DON)成为可能。
