Our mission

LNCE addresses energy and sustaibility challenges by addressing the fundamental key questions behind them. We use the tunability of well-defined nanocrystals to establish design principle of efficient and stable materials which store electricity and light into chemicals via conversion of low value molecules. We are particularly interested in the conversion of small molecules, especially CO2 and CO, expanding to fine chemicals. The goal is to create a more sustaiable chemical production.

1	Colloidal chemistry
2	Electrocatalysis
3	Photocatalysis

Our key projects

Tulip

We develop a new class of nanoparticles for the conversion of small molecules based on liquid metals. The idea of using liquid metals instead of conventional solid metals is that they will not deactivate and offer industry stable catalysts for chemical conversion. This grant is an ERC Consolidator.

Design strategies for stable catalysts in CO2 electroreduction

We develop strategies to create efficient and stable catalysts for converting CO2 into chemicals. These catalysts are based on copper instead of conventional precious metals.

Quantum dots for light-driven fine chemicals production

We develop light absorbing quantum dot materials to facilitate the production of fine chemicals using light.

This project is part of the big Swiss consortium NCCR Catalysis

Our mission

We advance materials discovery by uniting molecular simulation, data science, and AI. Through rigorous modeling, high-quality data, and holistic digital platforms, we accelerate breakthroughs in reticular chemistry and carbon capture, creating tools with real-world impact.

	Research topics
1	We use advanced computer simulations to understand how new materials work at the atomic level. This helps us predict important properties—such as how they hold heat, absorb gases, or move water—before we make them in the lab.
2	We combine large datasets with modern AI methods to identify which materials are most promising for a given job. Instead of testing thousands of materials experimentally, we let AI narrow the search to the most useful ones.
3	We synthesize and characterize new materials—such as bright, tunable luminescent compounds—to explore their properties experimentally and connect them to our simulations and AI models.

Our key projects

A unified platform linking material properties, process design, TEA and LCA to identify optimal CO₂-capture sorbents for real source–sink pairs.Used across >60 global case studies for system-level decisions.

Using data-driven MOF screening, we identified robust CO₂-binding “adsorbaphores” resistant to humidity. Led to synthesis of Al-PMOF and Al-PyrMOF, which outperform commercial sorbents under wet conditions.
