Canopy and understory nitrogen additions differentially regulate soil organic carbon fractions via litter–microbe–mineral interactions

Forest Ecosystems
The effects of nitrogen (N) deposition on forest soil organic carbon (SOC) are largely unclear, likely due to the divergent responses of particulate (POC) and mineral-associated carbon (MAOC).

A new geographically weighted stacked regression method for forest aboveground carbon storage estimation: A case study of bamboo forest

Ecological Indicators
Forest aboveground carbon storage (AGC) is a key criterion reflects the carbon sequestration capacity, health and productivity of forest ecosystem. Bamboo forests are potential to sequester carbon thereby are significant in climate change investigations.

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

Advanced 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.

Estimating the costs of atmospheric carbon reductions in Mexico [PDF]

, 2003
Trading in carbon emissions is a means of ensuring that supplies with the lowest marginal costs of emissions reduction are commissioned first. To analyse the potential for Mexican suppliers to participate in an emissions trading market, the relative cost-
