125. The physics of ultrafast CO2 reduction using cryogenic electrons

Julia Stähler (Humboldt-Universität zu Berlin)

Invited Talk

Global warming requires humanity to reduce atmospheric CO2 significantly - and fast. Chemically, CO2 reduction (i.e. electron attachment) is a vital step for its conversion to less harmful or even useful carbon-based products. One approach to capture CO2 is to freeze it at cryogenic temperatures before chemical modification. Whether or not single electron transfer to CO2 is feasible at these...

92. Tuning Spin-Charge Conversion at the hybrid heavy-metal/ organic semiconductor interface through Chiral Doping

Micro/Nano Engineering

Contributed Talk

Spintronics, the way forward to device miniaturization, leverages electron spin rather than charge. Though inorganic materials were predominantly given more attention in spin transport studies, organic semiconductor (OSC)/magnetic hybrid interfaces are quickly gaining interest, owing to the flexibility, scalability, and structural tunability of organic materials. Here, we probe the effect of...

43. Hybrid Laser–Chemical Functionalization of Stainless Steel Surfaces Using IR Picosecond Laser Pulses for Tailored Hydrophobicity

Micro/Nano Engineering

Contributed Talk

Functional metallic surfaces with tailored wettability are of increasing interest for applications requiring enhanced corrosion resistance, self-cleaning behaviour, and reduced fouling. While laser texturing and chemical functionalization are established approaches for producing hydrophobic metallic surfaces, their combined effect remains poorly understood. Addressing this challenge is...

116. Controlling Floquet-Feshbach resonances in an ultracold quantum gas

Quantum Optics

Contributed Talk

Resonant scattering is central to atomic, molecular, and optical physics and provides a powerful tool for controlling interactions in ultracold quantum gases. In ultracold atomic systems, magnetically tunable Feshbach resonances enable precise control of the interaction strength. Building on our recent demonstration that periodic magnetic-field modulation Floquet-engineers additional Feshbach...

37. Making Perovskite Photovoltaics Sustainable – Material Choice Guidelines from a Comprehensive Sustainability Perspective

Energy Systems

Contributed Talk

The research community has urged for broader sustainability considerations to guide the development of next generation photovoltaics (PV). We propose a practical sustainability framework with quantifiable indicators for ecological impact, planetary boundaries, social risks, and supply constraints. We apply this framework to raw material mining for a large-scale deployment scenario of...
