Deciphering Intricacies in Directional CO2 Conversion From Electrolysis to CO2 Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This review will delve into the inherent connections and distinctions of CO2‐directed conversion in ECO2RR and CO2 batteries, in terms of product types, catalyst selection, catalytic mechanisms, and electrochemical performances, while proposing a benchmarking framework for the evaluation of CO2 batteries and innovative CO2 battery configurations for ...

Synthesis of Cyclopropene‐Modified Fatty Acids Allows Single‐Cell Quantification of Uptake by Immune Cells

open access: yesAngewandte Chemie, EarlyView.
Cyclopropene fatty acids have been made that allow the study of fatty acid uptake in complex mixtures of immune cells with single cell resolution and combined with metabolic and proteomic analysis so that for the first time nutrient uptake can be correlated to the phenotype of single immune cell.

The importance of dissolved organic nutrients in the biogeochemistry of oligotrophic gyres

open access: yes, 2005
The aim of this thesis is to contribute to the observational database in order to address fundamental questions as to how dissolved organic nutrients influence N and P budgets, how they affect nutrient cycling and the sustainment of biological production

Nitrogen Isotopes in the Global Ocean [PDF]

open access: yes, 2013
Nitrogen is an essential nutrient for life. Its low abundance throughout much of the sunlit surface ocean limits the growth of primary producers that form the base of ocean ecosystems.

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky

open access: yesApplied 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.

Few-layer black phosphorus enables nitrogen fixation under ambient conditions

open access: yes
Nitrogen (N2) fixation is a key reaction in biological and industrial chemistry, which does not occur spontaneously under ambient conditions but often depends on very specific catalysts and harsh reaction processes.

Phosphorus limitation of soybean and alfalfa biological nitrogen fixation on organic dairy farms

open access: yes, 2010
Low plant available phosphorus limits legume growth and biological nitrogen fixation (BNF). This study examined, under controlled conditions, the relationship between soil phosphorus and alfalfa and soybean BNF on two contrasting low-P soils (Ontario ...

High-resolution two-dimensional quantitative analysis of phosphorus, vanadium and arsenic, and qualitative analysis of sulphide, in a freshwater sediment. [PDF]

open access: yes, 2008
Recently introduced techniques that can provide two-dimensional images of solution concentrations in sediments for multiple analytes have revealed discrete sites of geochemical behaviour different from the average for that depth (microniches).

Climate Change Mitigation in the Dairy Sector: Uncovering Heterogeneity Through Eco‐Efficiency Clubs

open access: yesAgribusiness, EarlyView.
ABSTRACT Combining climate change goals with economic targets is crucial for the dairy sector, which is a significant contributor to agricultural greenhouse gas (GHG) emissions worldwide. In this paper, we assess economic and climate change implications of dairy production with panel data of Irish dairy farms from 2013 to 2021.

Enantioselective Synthesis of Axially Chiral Diaryl Ethers via Rhodium‐Catalyzed [2 + 2 + 2] Cycloaddition

open access: yesAngewandte Chemie, EarlyView.
An enantioselective rhodium‐catalyzed [2 + 2 + 2] cycloaddition enables the synthesis of axially chiral diaryl ethers. Carbonyl coordination ensures high reactivity and regioselectivity, affording products bearing up to four stereogenic axes with good enantio‐ and diastereoselectivity.
