Nanostructured metals and semiconductors are promising building blocks for next generation solar energy conversion devices at low cost. From the optical perspective, nanostructure (NS) ensembles constitute a new class of metamaterial, where the optical properties of the ensemble are tuned by the individual NS type, geometry and collective arrangement. In the case of solar energy conversion into fuels, nanostructured or layered metal and metal oxide co-catalysts display performances that are morphology and size dependent.
June 11th 2019
From 11 to 21 June, DIFFER hosts the WPCD code camp for European fusion researchers in the EUROfusion Project on Code Development for Integrated Modelling (WPCD). WPCD supports the achievement of the European Fusion Roadmap at Horizon 2020 goals, via the development of existing modelling codes with a particular focus on integrated modelling. The DIFFER code camp will offer a venue for WPCD members to meet in person and advance the collaborative development of  workflows / verification and validation.

Polymer membranes for gas separation are extensively applied on large scale in many (petro)chemical processes. With the electrification and transition to a circular economy, the number of new applications is expanding, due to their low footprint and low energy consumption for separation. Though as existing membranes are originally designed for other separations, this requires tailoring of membrane performance. In this presentation I will discuss the molecular design of polymer membranes for sustainable process applications.

It is critical to understand how electrochemical materials change, transform, and degrade within devices to enable the development of next-generation energy storage and conversion systems. In my research group, multi-scale in situ techniques are used to reveal reaction mechanisms and interfacial transformations in materials for batteries and catalysis.

The impact of a laser pulse onto a liquid drop can lead to a violent response: plasma formation and local boiling induce a strong propulsion and deformation of the drop and eventually rupture the liquid into tiny pieces. When drops impact onto a solid surface, similar deformation and fragmentation occurs. Hot liquid metal drops impacting a cold substrate in addition freeze upon contact, which strongly alters the drop dynamics. I will discuss the fundamental physics behind these phenomena and their application in industrial plasma sources used for extreme ultraviolet nanolithography.
