  1. 1. 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

  2. 2. Surface Functionalization of Nanowires Using Silane-PEG Compounds

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hedvig Ekfors Elvin; [2022]
    Keywords : Functionalization; Nanowires; Silanization; Surface Chemistry; Materials Chemistry; Chemistry;

    Abstract : Introduction: GaP nanowires were functionalized using silane-PEG-NH2 and compared with cellulose acetate, PAcrAm™-g-(PMOXA, amine, silane) and a non-functionalized reference sample. Functionalization would allow strong, covalent anchoring of antibodies instead of adsorption. READ MORE

  3. 3. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Stéphanie Nyström; [2022]
    Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  4. 4. Development of Next-Generation Optical Tweezers : The New Swiss Army Knife of Biophysical and Biomechanical Research

    University essay from Umeå universitet/Institutionen för fysik

    Author : Daniel Nilsson; [2020]
    Keywords : optical tweezers; optical fiber tweezers; optical fiber; optical trapping; manipulation; optical force; cell trapping; biophysical; physicochemical; biomechanical; research; next-generation; raman spectroscopy; holographic optical tweezers;

    Abstract : In a time when microorganisms are controlling the world, research in biology is more relevant than ever and this requires some powerful instruments. Optical tweezers use a focused laser beam to manipulate and probe objects on the nano- and microscale. READ MORE
