A catalytic converter reduces harmful emissions from your vehicle, turning pollutants into less harmful substances. It improves engine efficiency, reduces air pollution, and helps you comply with emission regulations. When replacing it, ensure you choose a high-quality, compatible part. Dynovox Parts offers a range of certified catalytic converters to keep your vehicle running smoothly and efficiently
Theriouthly.
WHY so many O2 #sensors.
All you need is up from #catalytic converter and downstream. Even if you got a V #engine, a single cat converter would be plenty adequate, along a single downstream sensor.

"Here, we report a rationally designed #organometallic #catalytic system using earth-abundant metals that achieves Nylon-6 #depolymerization under mild and benign solvent-free conditions at unprecedented rates and selectivity. This process is effective for diverse commodity end-of-life articles such as fishing nets, carpets, clothing, and #plastic mixtures."

To advance crop productivity improvement efforts, the authors integrated crystal structure-guided changes from a highly effective red algae Rubisco into a related bacterial enzyme to improve its CO2-fixing traits that, in tobacco, enhanced photosynthesis and growth.
"Here, we use x-ray crystallography and cryo–electron microscopy to chart the structural changes undergone during the progress of the #enzyme through the reaction. We identify a single active site that has evolved to bind, individually and sequentially, substrates that satisfy structural and #chemical criteria to position reactive parts next to the #catalytic triad for reaction"
