Pore morphology in thermally-treated shales and its implication on CO₂ storage applications: A gas sorption, SEM, and small-angle scattering study

A combination of high-resolution imaging, low-pressure gas adsorption, and small-angle X-ray and neutron scattering quantifies changes in the pore characteristics of pulverized shale samples under oxic and anoxic environments up to 300 ℃. Clay-rich early-mature shales have a fair potential to generate hydrocarbons, the total organic carbon...

High-pressure homogenized citrus fiber cellulose dispersions: Structural characterization and flow behavior

Functionalized biomass waste sources of cellulose have drawn attention due to their high availability and sustainability properties. In this work we characterize the structural and flow properties of high-pressure homogenized citrus fiber cellulose dispersions, employing SAXS, rheology and rheo-MRI techniques. The high-pressure treatment...

Towards multi-functional SiO₂ @YAG: Ce core–shell optical nanoparticles for solid state lighting applications

This paper aims to investigate the synthesis, structure, and optical properties of SiO₂ @YAG:Ce core–shell optical nanoparticles for solid state lighting applications. YAG:Ce phosphor is a key part in white light emitting diodes (LEDs), with its main functionality being the generation of yellow light. Generated yellow light from...

Small-Angle Scattering by Cellulose: Structural changes in cellulosic materials under chemical and mechanical treatments

Humanity needs to increase use of renewable sources of materials and energy. Biomass can be used for both of these needs. Cellulose is the main component of biomass. Understanding the multi-level hierarchical structure of cellulose holds the key tomultiple applications of this material. One of the promising applications of lignocellulsic biomass...

A versatile shear cell for investigation of structure of food materials under shear

A versatile cell for X-ray and neutron scattering experiments on samples under shear has been designed. To our knowledge, it is the first shear cell which can be used for both SAXS and SANS in respectively synchrotron or reactor beamlines. The cell is mainly intended for scattering experiments in so-called “1–2 plane geometry” but can also be...

Microstructure Control of Fire-resistant, Low-alloy Steel; An in-situ 3D X-ray Diffraction and A Small-angle X-ray Scattering Study

The research presented in this thesis aims at deepening our understanding of the formation of the microstructure of steel during thermal processing in order to control the microstructure and thereby improve the fire-resistance of low-alloy steel. The strength of steel decreases during a fire mainly due to the following changes in the...
