Nitrogen and Sulfur Co‐Doping Modulates the Interface Interaction Between Pt Nanoparticles and Hollow Carbon Nanospheres for Boosted Methanol Oxidation Performance

open access: yesCarbon Neutralization, Volume 5, Issue 2, March 2026.
The co‐doping of N and S significantly strengthens the metal‐support interaction of Pt@N,S‐HCN, thereby promoting the rearrangement of Pt electron structures (Pt°→Ptx+) and increasing the density of Pt active sites. This enhances the adsorption affinity of Pt active centers for OH intermediates and reduces the binding strength of CO, ultimately ...

Enhanced below‐ground functioning is associated with higher plant resistance against drought: Implications for ecosystem functions

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
The results suggest that the subordinate species achieves higher drought resistance in biomass and soil functions via increased below‐ground functioning. The data presented here provide a basis to explain the underlying mechanisms behind the response of grassland communities and their C cycling to drought.

What makes the dorsomedial frontal cortex active during reading the mental states of others?

open access: yesFrontiers in Neuroscience, 2013
The dorsomedial frontal part of the cerebral cortex is consistently activated when people read the mental states of others, such as their beliefs, desires, and intentions, the ability known as having a theory of mind (ToM) or mentalizing. This ubiquitous
