Time-Resolved Dynamics During the Initial Decline in Catalytic Activity of the CO + NO Reaction Over Platinum – Elucidating the Role of NCO

April 29, 2025

SSRN

The temporal evolution of the reduction of NO by CO over Pt/Al2O3 as a layered and powdered catalyst in flow reactors is investigated as a function of temperature and stoichiometry and at low concentrations typical for emission control. The focus is mainly on the early decline in conversion over freshly reduced or regenerated catalysts as well as on the reaction of NO with isocyanate previously adsorbed on the surface. Results suggest presented suggest that isocyanate formation promotes dissociation of adsorbed NO, thus temporarily counteracting the well-known inhibiting effect of CO adsorption.

High-throughput solid microsampling through stochastic robotic automation

Solid sampling at the sub-milligram and milligram scale remains a major bottleneck for high-throughput chemistry or material sciences, as existing approaches rely on manual handling or slow deterministic microsampling that do not readily scale.

Here we present STORMS, an automated STOchastic Robotic MicroSampling system that enables fast, reliable and parallel sampling of solid materials at sub-milligram and milligram masses.

Parameter efficient multi-model vision assistant for polymer solvation behaviour inference

Polymer–solvent systems exhibit complex solvation behaviours encompassing a diverse range of phenomena, including swelling, gelation, and dispersion. Accurate interpretation is often hindered by subjectivity, particularly in manual rapid screening assessments. While computer vision models hold significant promise to replace the reliance on human evaluation for inference, their adoption is limited by the lack of domain-specific datasets tailored, in our case, to polymer–solvent systems.

Continuous Flow Synthesis of Diglycolamides for Rare-Earth Elements Recovery: Algorithm-Accelerated Reaction Optimization Coupled with Automated Extraction Evaluation

A first example of diglycolamide flow synthesis was developed, showcasing algorithm-accelerated reaction optimization and its potential to accelerate ligand discovery and enable autonomous, AIcontrolled manufacturing of critical materials. The increasing demand for manufacturing rare-earth elements (REEs) as critical materials has intensified research on sustainable synthesis of advanced extractants such as diglycolamides (DGAs).
