Novel niobium-doped titanium oxide towards electrochemical destruction of forever chemicals.

Electrochemical advanced oxidative processes (EAOP) are a promising route to destroy recalcitrant organic contaminants such as per- and polyfluoroalkyl substances (PFAS) in drinking water. Central to EAOP are catalysis-induced reactive free radicals for breaking the carbon fluorine bonds in PFAS. Generating these reactive species electrochemically at electrodes provides an advantage over other oxidation processes that rely on chemicals or other harsh conditions.

The role of oxygen in stimulating methane production in wetlands.

Methane (CH ), a potent greenhouse gas, is the second most important greenhouse gas contributor to climate change after carbon dioxide (CO ). The biological emissions of CH from wetlands are a major uncertainty in CH budgets. Microbial methanogenesis by Archaea is an anaerobic process accounting for most biological CH production in nature, yet recent observations indicate that large emissions can originate from oxygenated or frequently oxygenated wetland soil layers.

Impact of bromide exposure on natural organochlorine loss from coastal wetland soils in the Winyah Bay, South Carolina.

Naturally formed halogenated organic compounds are common in terrestrial and marine environments and play an important role in the halogen cycle. Among these halogenated compounds, chlorinated organic compounds are the most common halogenated species in all soils and freshwater sediments. This study evaluated how a previously observed phenomenon of bromination of organic matter in coastal soils due to salt-water intrusion impacts the stability and fate of natural organochlorine (org-Cl) in coastal wetland soils.

Proteomic analysis reveals APC-dependent post-translational modifications and identifies a novel regulator of β-catenin.

Wnt signaling generates patterns in all embryos, from flies to humans, and controls cell fate, proliferation and metabolic homeostasis. Inappropriate Wnt pathway activation results in diseases, including colorectal cancer. The adenomatous polyposis coli (APC) tumor suppressor gene encodes a multifunctional protein that is an essential regulator of Wnt signaling and cytoskeletal organization.
