A Metal‐Free Carbon Monoxide Prodrug Suppresses Metastasis of Pancreatic and Breast Cancer

Advanced Science, EarlyView.
A metal‐free carbon monoxide (CO) prodrug, CO‐116, delivers controlled systemic CO without inhalation. CO suppresses the HRG1–heme axis, reducing intracellular heme availability. Attenuation of this pathway inhibits metastatic progression in pancreatic and triple‐negative breast cancer models.

The Development of Models for Carbon Dioxide Reduction Technologies for Spacecraft Air Revitalization [PDF]

Through the respiration process, humans consume oxygen (O2) while producing carbon dioxide (CO2) and water (H2O) as byproducts. For long term space exploration, CO2 concentration in the atmosphere must be managed to prevent hypercapnia. Moreover, CO2 can

Liquid Bismuth Catalyst Enables High‐CO‐Selectivity in CO2 Hydrogenation

Advanced Science, EarlyView.
This work introduces a dynamic liquid bismuth catalyst for efficient CO2‐to‐syngas conversion. Stabilized molten Bi nanodroplets on a defective VOx support enable a reversible Bi3+/Bi0 redox cycle at moderate temperatures. Mechanistic insights reveal that Ni‐Bi dual sites synergistically activate H2 and cleave CO2, leading to high CO selectivity ...

High‐Throughput Screening and Interpretable Machine Learning for Rational Design of Bimetallic Catalysts for Methane Activation

Advanced Science, EarlyView.
ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...
