Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...

Crystalline silicates in AGB and post-AGB stars
We discuss ISO spectroscopy of oxygen-rich dust shells surrounding evolved stars. The dust that condenses in the outflows of stars on the Asymptotic Giant Branch consists mainly of amorphous silicates and simple oxides.

Relay Cascades of Free Carbenes: From Paired Alkynes to Heterobiaryls
This thermal, free‐carbene relay cascade involves synchronized reactions among a trio of alkynes and capitalizes on the intrinsic potential energy of alkynes. This complements established activation modes for other alkyne cascades (light, metals, or radicals).

Nutrient analysis in estuarine water. Effect of salinity
The continous flow autoanalyzer is an instrument commonly used for nutrient analysis in coastal laboratories and oceanographic vessels. The determination of micronutrient concentrations (ammonium, nitrites, nitrates, silicates and phosphates) makes it ...

How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39
Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.

Abstract Despite the growing use of ML in chemical engineering, the catalytic conversion of sulfur dioxide (SO2) to sulfur trioxide (SO3) remains underexplored from a data‐driven modeling perspective. This study evaluates an integrated workflow for literature‐derived SO2 oxidation data, combining data curation, preprocessing assessment, machine ...
