67,000 homes in Ireland still use peat for heating. However, Bord Na Mona stopped extracting peat last year and closed its last peat power station. Now restoring peatlands which in a dried out, denatured state are carbon emitters. Big wind farms now on former extraction sites too. A great deal of historical damage has been done.

JWST spectroscopy of a blue binary cold classical Kuiper belt object
We present observations of two binary systems within the cold classical region of the Kuiper belt -- 2001 XR254 and 2016 BP81 -- obtained with the JWST Near-Infrared Spectrograph. The measured reflectance spectrum of 2001 XR254 is characteristic of the red cold classicals, with strong features due to carbon dioxide, carbon monoxide, and methanol ices. In contrast, 2016 BP81 is a blue binary, with a water-ice-rich surface composition. The two components of the 2016 BP81 binary display identical …

A survey on geometric frameworks for action-dependent classical field theories and their relationship
This work presents a comprehensive overview of three recently developed geometric frameworks for the study of classical action-dependent field theories. Specifically, the three underlying geometric structures - namely, k-contact, k-cocontact, and multicontact - are first introduced, and then used to develop the Lagrangian and Hamiltonian formalisms of the aforementioned theories. Finally, the relationship among these three types of structures is analyzed in the case of trivial bundles; as well …

Origins of chalcogenide perovskite instability
Chalcogenide perovskites, particularly II-IV ABS3 compounds, are a promising class of materials for optoelectronic applications. However, these materials frequently exhibit instability in two respects: 1) a preference for structures containing one-dimensional edge- or face-sharing octahedral networks instead of the three-dimensional corner-sharing perovskite framework (polymorphic instability), and (2) a tendency to decompose into competing compositions (hull instability). We evaluate the stabi…
