Webb2 aug. 2004 · A small angle x-ray scattering (SAXS) based technique has been demonstrated to have the capability of characterizing the average pitch size and pattern width to subnanometer precision. WebbThe scattered x-rays are collected on a 2-dimensional area detector azimuthally in 360 degrees at a continuous range of scattering angles which deviate from the direct, transmitted beam. The scattering angle, which we define by convention as 2 θ, defines a “probe length” expressed as D = 2π /q, where q = 4 π sin ( θ )/ λ, in which λ ...

It provides information about the sizes and shapes of proteins and complexes in a broad range of molecular sizes ranging from a few kDa to GDa and under various experimental …
Webb29 juli 2024 · Usually, to characterize bacterial cells’ susceptibility to antimicrobials, basic microbiology techniques such as serial dilutions or disk assays are used. In this work, we present an approach focused on combining static light scattering (SLS) and ultra-/small angle X-ray scattering (USAXS/SAXS). This approach was used to support microbiology … Webb3 sep. 2024 · Abstract. In this study, we present a combined small-angle neutron and X-ray scattering (SANS and SAXS) study of the nanoscale structure of cortical bone specimens from three different species. The variation of the scattering cross section of elements across the periodic table is very different for neutrons and X-rays.
