Solid State Defect Emitters With no Electrical Activity

open access: yesAdvanced Science, EarlyView.
Point defects may introduce in‐gap states that alter electrical properties and lower the optical excitation threshold. It is thus widely assumed that solid‐state defect emitters alter the host conductivity. This study demonstrates, on a particular defect in 4H silicon carbide, that a yet unrecognized class of point defects exists that are optically ...

Stacking Interventions Enhances Carbon Removals and Profitability of Livestock Production Systems

open access: yesAdvanced Science, EarlyView.
The study indicates that stacking multiple interventions aimed at maximising soil organic carbon (SOC) sequestration and enteric methane (CH4) reductions realizes greater abatement and profit do any singular intervention, especially when SOC sequestration accounts for a significant proportion of greenhouse gas emissions (GHG) mitigation. Abstract While
