Improved Corrosion Resistance of a Micro‐Alloyed Carbon Steel Assessed by Multi‐Element Electrical Resistance Probes and Coupons in Natural Seawater and Soil

Materials and Corrosion, EarlyView.
Multi‐element electrical resistance probes fabricated from industrial carbon steels enable real‐time corrosion monitoring in natural seawater and soil. A micro‐alloyed grade (AMLoCor) demonstrates up to 2.4 times improved uniform corrosion resistance over conventional S355 GP steel.

Where Have I Seen You Before? Networks, Trust and Reciprocity as a Source of Collaboration in the Public Service

Public Administration and Development, EarlyView.
ABSTRACT Although some studies focus on how bureaucrats' interactions with one another affect performance, they rarely focus on why these public servants collaborate. Bureaucrats' collaboration matters because it can significantly contribute to achieving policy goals.

The impact of tropical forests on local climate: Comparing recent research with conservation practitioner information priorities

People and Nature, EarlyView.
Abstract The local‐scale climate impacts of tropical forests (LCIF), such as reducing temperatures and increasing rainfall, are directly relevant to climate change adaptation and mitigation. Strengthening understanding of these local climate benefits can encourage actions to conserve natural forests, with positive implications for climate resilience ...
