Electronic‐State Programming of Ultrasmall CeO2 Switches H2O2 Activation From Radical to Bio‐Inspired Nonradical 1O2 Generation for Combating Antibiotic Resistance

Advanced Science, EarlyView.
A scalable synthesis of carbon‐supported ultrasmall CeO2 nanoparticles with precisely tunable Ce electron density is reported. Electron‐lean Ce sites activate H2O2 exclusively via a nonradical pathway, enabling efficient HOBr and 1O2 production analogous to bromoperoxidase for contaminant and antibiotic resistance removal.

Use of environmental sequencing in evaluating fungal response to peatland degradation [PDF]

Mires and Peat
Central European peatlands are critically endangered by climate change, eutrophication, disturbed water regime and inappropriate management. This leads to their degradation, which affects all components of these habitats including fungi, and ...

Bacterial abundance and pH associate with eDNA degradation in water from various aquatic ecosystems in a laboratory setting

Frontiers in Environmental Science, 2023
Environmental DNA (eDNA) has been widely used in biomonitoring and has major advantages compared to traditional methods such as counting observations. However, the persistence of eDNA within an ecosystem can lead to false-positive results on the presence
