The temperature sensitivity of stable organic carbon storage rises with increasing soil salinity

open access: yesPlant, Soil and Environment
Soil salinisation is a key determinant in soil fertility decline, exerting a direct negative impact on soil organic carbon. In the context of global warming, investigating the response mechanisms of soil organic carbon pools with varying salinity levels ...

A comparative analysis of two different analysers used for determination of the Total Organic Carbon in pharmaceutical grade water [PDF]

open access: yes, 2012
Total Organic Carbon (TOC) is a routine test for pharmaceutical grade water. Several manufacturers supply equipment of different designs but there is a dearth of published, peer-reviewed, information evaluating the various analysers.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Non‐Floodplain Wetlands Are Carbon‐Storage Powerhouses Across the United States

open access: yesEarth's Future
Understanding wetland carbon stores and dynamics are critical to managing global carbon flux. Non‐floodplain wetlands (NFWs) are hydrologically dynamic and globally prevalent inland wetlands distal to fluvial flowpaths, lacustrine‐fringing areas, and ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Effects of Plant Diversity on Soil Organic Carbon in Alpine Meadow in Northeastern Qinghai-Xizang Plateau

open access: yesGaoyuan qixiang
Plant diversity significantly affects the structure and function of ecosystems and plays a crucial role in soil organic carbon sequestration.In the past, the effects of plant diversity on soil organic carbon were mostly carried out under artificial plant

MnI‐Functionalized Covalent Organic Framework as Efficient Electrocatalyst for CO2 Reduction in a Catholyte‐Free Zero‐Gap Electrolyzer

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.
