Informing the potential of mature temperate forests as natural climate solutions: Changed fine root biomass and morphology under elevated CO2

PLANTS, PEOPLE, PLANET, EarlyView.
The land carbon sink absorbs approximately 25% of anthropogenic CO2 emissions, with forests accounting for most. Managing forests as Natural Climate Solutions is therefore a societal imperative, requiring models of where and how long carbon resides within these ecosystems. We investigated the effects of elevated CO2 on fine roots, the primary source of

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Assessing Seasonal Effects on Identification of Cultivation Methods of Short–Growth Cycle Brassica chinensis L. Using IRMS and NIRS

Foods
Seasonal (temporal) variations can influence the δ13C, δ2H, δ18O, and δ15N values and nutrient composition of organic (ORG), green (GRE), and conventional (CON) vegetables with a short growth cycle.

Establishment of a method for determining the origin of glutamic acid in processed food based on carbon and nitrogen stable isotope ratios

Heliyon, 2019
We developed a discriminant method based on the stable isotope ratio of carbon and nitrogen (δ13C and δ15N) to evaluate whether monosodium glutamate (MSG) is used in processed food samples.

Exploratory Analysis of Sustainable Consumption and Production Factors in Services: Insights From Four Case Studies Using Interpretive Structural Modeling

Sustainable Development, EarlyView.
ABSTRACT This study investigates how 14 sustainable consumption and production (SCP) factors interact across four service categories—Mass Service, Professional Service, Service Factory, and Service Shop—using interpretive structural modeling (ISM). ISM enables the identification and hierarchical classification of interdependencies among SCP factors in ...

Working standards and analytical framework for CSIA: isotopic composition (δ13C, δ15N, and δ34S) of 21 amino acids and 7 nucleobases

Progress in Earth and Planetary Science
We determined the carbon and nitrogen isotope compositions of biologically important 21 amino acids and 7 nucleobases, which are used as working standards. These isotopic compositions were determined using a high-sensitivity elemental analyzer coupled to

An Automatic Injection Device and the Method for Carbon and Oxygen Isotopes Analyses of Carbon Monoxide

Zhipu Xuebao
Carbon monoxide (CO) is an essential component of air, and it arises from anthropogenic sources and natural sources. These different sources of CO have significant differences in carbon and oxygen isotopic values, therefore the carbon and oxygen isotopic

Circular Economy and Sustainable Development in China's Textile Industry: Challenges and Innovation Pathways

Sustainable Development, EarlyView.
ABSTRACT The circular economy (CE) is increasingly promoted as a strategy for addressing environmental degradation and resource inefficiencies. Despite growing policy support, CE implementation remains fragmented in many resource‐intensive industries, particularly in emerging economies. This study investigates barriers to CE adoption in China's textile

Outer‐Sphere Tuning of Synthetic Iron–Sulfur Clusters Within Nanoscale Cage Frameworks

Small, EarlyView.
Noncovalent encapsulation of a synthetic iron–sulfur cluster within hydrophobic, naphthalenediimide (NDI)‐paneled cages is shown to lead to dramatic changes in the electronic structure and covalency of the Fe─S core. ABSTRACT As atomic‐scale archetypes for multi‐electron transfer, iron–sulfur clusters are compelling candidates for the design of redox ...
