Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

open access: yesRiver, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Leveraging P‐Reactivity and Ring Strain to Generate Molecular Diversity in Dithienylethenes‐Based Photochromes

open access: yesChemistryEurope
We synthesized and studied phosphetene‐bridged dithienylethenes (DTEs), featuring 4‐membered P‐rings, exploring their P‐chemistry and ring strain reactivity that allowed us to isolate 5‐membered oxophospholenes. Experimental and density functional theory
