1. Controlled polymerization of levoglucosenone-derived enynes to give bio-based polymers with tunable degradation rates and high glass transition temperatures 

   Jung, Eunsong; Rizzo, Antonio; Ryu, Hanseul; et al. (2025)

   Chemical Science

   In recent years, pollution from plastic waste has intensified the demand for sustainable polymers. Hence, biomass-derived degradable polymers offer a promising solution. For example, levoglucosenone, a readily available biomass product from cellulose pyrolysis, is an attractive building block for polymer synthesis. However, the metathesis polymerization of levoglucosenone-derived monomers has been difficult to control due to poor monomer ...

2. From smallholder to commercial farming: the impact of termite mound levelling and spatial heterogeneity in mound morphology on soil organic carbon in Miombo woodlands, Central Africa 

   Ou, Xiaojing; Sebagenzi, Guy David; Mujinya, Basile Bazirake; et al. (2025)

   Landscape Ecology

   ContextThe recent expansion of commercial agriculture in the Miombo woodlands of central Africa has led to widespread levelling of termite mounds. These mounds contain significantly lower soil organic carbon (SOC) than surrounding soils, and their levelling could largely reduce SOC content in the plough layer, which remains understudied.ObjectivesWe aim to investigate the effects of mound levelling on SOC of the plough layer in a 1.5 km2 ...

3. An Oxidation Gradient Straddling the Small Planet Radius Valley 

   Cherubim, Collin; Wordsworth, Robin; Bower, Dan J.; et al. (2025)

   The Astrophysical Journal

   We present a population-level view of volatile gas species (H2, He, H2O, O2, CO, CO2, CH4) distribution during the sub-Neptune to rocky planet transition, revealing in detail the dynamic nature of small planet atmospheric compositions. Our novel model couples the atmospheric escape model IsoFATE with the magma ocean-atmosphere equilibrium chemistry model Atmodeller to simulate interior-atmosphere evolution over time for sub-Neptunes around ...

4. A warming pulse in the Antarctic continent changed the landscape during the Middle Ages 

   Forte, Emanuele; Azzaro, Maurizio; Cannone, Nicoletta; et al. (2025)

   COMMUNICATIONS EARTH & ENVIRONMENT

   The Antarctic landscape is one of the most stable environments on the Earth, at least since approximately 14 million years ago when most glaciers in continental Antarctica changed from temperate to cold-based, and previous extensive fluvial activity disappeared. Here, we detected a large landscape change on a coastal glacier in continental Antarctica (Boulder Clay Glacier) that occurred in the Medieval Warm Period. Such change consists ...

5. Performance of Cryogenic Adsorbents for Use in Methane Bulk and Clumped Isotope Analysis 

   Kueter, Nico; Zhang, Naizhong; Meissner, Jan G. C.; et al. (2025)

   Rapid Communications in Mass Spectrometry

   RationaleCryogenic trapping of methane is essential for bulk and clumped isotope analyses, requiring adsorbent materials that enable efficient recovery and preserve isotopic signatures. This study evaluates the performance - capacity, isotopic fractionation, and ease of use - of silica gels, zeolite molecular sieves, and activated carbon under various trapping and desorption conditions. A focus is set on the preservation of methane clumped ...
