Isotope sample preparation of diatoms for paleoenvironmental research.
PLoS ONE, 2023 Isotopes in diatoms are increasingly used in palaeoenvironmental studies in both lacustrine and marine settings, enabling the reconstruction of a range of variables including temperature, precipitation, salinity, glacial discharge, carbon dynamics and ...

Nutrients cause consolidation of soil carbon flux to small proportion of bacterial community
Nature Communications, 2021 The fate of soil carbon depends on microbial processes, but whether different microbial taxa have individualistic effects on carbon fluxes is unknown.

The Emergence of Carbon Isotope Exchange
Angewandte Chemie International Edition, 2019 Significant progress in C-C bond activation with transition metals has recently enabled the development of several carbon isotope exchange reactions. These methods are based on C-C bond decarboxylative carboxylation reactions in the presence of selected transition metals and labelled carbon monoxide or carbon dioxide.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Pyrolysis experiment and reservoir-forming potential of epimetamorphic rock
Petroleum Exploration and Development, 2009 By taking pyrolysis experiments and analyzing composition and carbon isotopes of pyrolysis products, the hydrocarbon generation potential and products geochemistry of very low-grade epimetamorphic rocks were studied.

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

FEBS Open Bio, EarlyView.The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Advanced Engineering Materials, EarlyView.This review highlights advances in lightweight, lead‐free polymer nanocomposites for diagnostic X‐ray shielding. By linking filler chemistry, dispersion, architecture, and photon interaction mechanisms, it establishes structure–performance relationships guiding material design.
