Characterization of ethanol induced protein gels by ultra-small angle x-ray scattering and rheological measurements
… in binary solvent systems of ethanol and water. Ultra-small angle X-ray scattering (USAXS) was used to characterize zein ensembles formed in aqueous ethanol. The results showed that zein assemblies possessed three levels of structural hierarchy. Zein formed rod-like structures at one dimension …

The topology and electrical properties of nanoparticle networks
… using laboratory and synchrotron based small angle X-ray scattering and ultra-small angle X-ray scattering, as well as with a new surface scattering technique developed for this research, which can be described as wide angle low q scattering. A new scaling model applied to the small …

Morphology-Property Relationships in Semicrystalline Aerogels of Poly(ether ether ketone)
… MW and increasing compressive modulus. Contact angle and contact angle hysteresis revealed that PEEK aerogels have a high contact angle, exceeding the conditions necessary to be classified as superhydrophobic materials. PEEK aerogel contact angle decreases with increasing density and a very low …

The Effect of Ionomer Architecture on the Morphology in Gel State Functionalized Sulfonated Syndiotactic Polystyrene
… based on the amplitude of the signal measured by small angle x-ray scattering. Additionally, methods were developed to describe both the distribution of ionic multiplets, which varies between blocky and randomly functionalized systems, but also the distribution of crystals. At a larger scale …

Non-destructive Electrical Characterization of Controlled Waspaloy Microstructures
… alternate characterization techniques such as Ultra Small Angle X-ray Scattering (USAXS), Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) to gain a complete understanding of the microstructural transformations and the associated mechanisms. Three different sets of controlled …

Relating structural properties to saltiness perception of model lipoproteic gels
… of fat (Rg,f) in the SLCs was quantified using ultra-small-angle X-ray scattering with a synchrotron-source. Serum release, which is the amount of liquid compressed out from the SLCs, and textural properties were measured using a texture analyzer. A conductivity meter was used to measure the in …

Developing a Microbubble-based Contrast Agent for X-ray Phase Contrast Imaging to Detect Neovasculature in Breast Cancer
X-ray phase contrast imaging (XPC) generates contrast from refraction and scattering of X-rays, unlike absorption in conventional radiology. This technique greatly improves the sharpness of boundaries and reveals micro-structured tissues that are not easily detected by conventional absorption-based …

Investigation of Phase-Separated Polymeric Materials via X-ray Scattering Techniques
… materials and their characterization via ultra-small, small, and wide-angle X-ray scattering methods (USAXS/SAXS/WAXS). Specifically, these experimental techniques are employed to investigate the phase separated morphologies that impart unique properties to each class of materials and …
