  1. 6. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Author : Qianhui Liu; [2022]
    Keywords : Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Abstract : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  3. 7. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts

    University essay from Lunds universitet/Kemiska institutionen

    Author : David Llorens Rauret; [2022]
    Keywords : Facet control; in-situ TEM; nanoparticle heterostructures; phase transformation; transition metal phosphides; inorganic nanomaterials; Chemistry;

    Abstract : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. READ MORE

  4. 8. Elastic hyperspectral lidar for detecting coherent backscatter from insects

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Lauro Müller; [2022]
    Keywords : Nanosopy; Thin film physics; Hyperspectral; Lidar; Super continuum; Insects; Coherent scattering; Infrared Spectroscopy; Hyperspectral Imaging; Biophotonics; Technology and Engineering;

    Abstract : Insects play a major role in the ecosystem and are an important factor for biodiversity. Using laser remote sensing to distinguish and monitor the millions of insects in-situ, holds large potential to speed up and improve the otherwise time consuming process of trapping and subsequent analysis.
