  • Room: 2.06
  • Host: Martin Wolf
  • Topic: Discussion and debate formats, lectures
Correlation plays a central role in emergent phenomena. Examples include, among others, quantum ground states and collective excitations. Here, I will discuss what we can learn from time-domain views of correlation in two dimensional (2D) vdW materials. [more]

Reverse Water Gas Shift Activity of FexNi Catalysts on Metal Oxide-Overlayered γ-Al2O3 Supports

Power-to-Liquid (PtL) processes, which produce liquid fuels from captured CO₂ and green H₂ via methanol synthesis or Fischer-Tropsch synthesis, offer a promising route to sustainable carbon-based energy carriers for sectors that cannot be readily electrified. [more]

The A+ Upgrade to Advanced LIGO and Applications of Hydroxide Catalysis Bonding

Advanced LIGO (the Laser Interferometer Gravitational-Wave Observatory) is designed to measure the quadrupolar strain of space itself arising from passing gravitational waves and in 2015 made the first observation of a binary black hole merger [Abbot et al, Phys Rev A, 116, 061102 (2016)]. [more]

Shedding Infrared Light on Molecules: From Molecular Polaritons to Hyperspectral Imaging

Mid-Infrared (MIR) light can interact with molecules by selectively exciting molecular vibrational modes. On one hand, in combination with photonic structures, MIR can target specific vibrational states of molecular to influence chemical reactions; on the other hand, IR spectroscopy has long been used as a molecular sensing tool. In this talk, I will discuss recent advancement in my lab, focusing on these two key topics. In the first topic, I will explain how photonic environments can modify molecular dynamics through strong light-matter coupling. This strong coupling leads to the molecular vibrational polaritons – a hybrid quasiparticle between light and matter. Using two-dimensional infrared (2D IR) spectroscopy, we have demonstrated that strong coupling to photonic environments can efficiently promote energy transfer within or between molecules, subsequently slowing down competing reaction pathways. This research provide insights into designing photonic structures to modify chemical landscapes and influence reaction pathways. In the second topic, I will present the latest development in fast-scanning vibrational sum frequency generation (VSFG) microscopy, tailored to differentiate collagen tissues in healthy and tumorous conditions. We revealed distinct spectral signatures between healthy and tumorous tissues, which arise from the coherent nature of VSFG signals – akin of a microscopic Young’s double slit experiment. VSFG’s unique power to resolve varying alignments of collagen fibrils empowers it as a distinctive label-free technique for tumor identification in the future. [more]

German-New Zealand Green Hydrogen / He Honoka Hauwai & Catalysts for H2 production and CO2 reduction

The increasingly severe impacts of climate change demand us to: (a) reduce energy use (b) decarbonise existing high emissions industrial processes and (c) rapidly replace of our present range of carbon-emitting fossil fuels (coal, oil, natural gas) by a suite of carbon-zero and carbon-neutral fuels.
