Methylene‐Bridged Calixarene Polyhedra: An Elusive Class of Symmetric Molecular Architectures

open access: yesHelvetica Chimica Acta, EarlyView.
An overview of purely hypothetical methylene‐bridged calixarene polyhedral molecular architectures is presented. In addition to the five previously postulated structures, we propose a calix[5]arene‐based icosidodecahedron as a new member of this class. Computational assessments of stability and strain indicate that methanospherophane is likely the most

Wildfires' Cost for Societal Welfare: Economic Evaluation of Forestry Ecosystem Services Losses in Southern Italy

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forest ecosystem services (ESs) are garnering increasing public attention as awareness grows regarding society's fundamental dependence on them for well‐being. Forest fires, one of the major disturbances of ESs, are becoming more frequent and destructive, exacerbated in part by climate change.

A Bibliometric‐Based Review of Biochar for Salt‐Affected Soil Restoration: Mapping Research Trends and Future Directions

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT In recent years, biochar has been studied for its range of applications. Recognized by the IPCC as a key Carbon Dioxide Removal (CDR) strategy, it also stands out as an important tool for reclaiming degraded lands, including vast global areas affected by salinity, such as those in China, India, and Australia.
