The most common process used for iPP film production is the tenter process, where an iPP sheet is stretched below its melting point by sequential biax- ial drawing. Therefore, the understanding of the iPP spherulite deformation mechanism during drawing is very important for designing polypropylene ...
Room temperature X-ray diffraction data collection forTthSHMT crystals was carried out on a Rigaku HighFlux HomeLab instrument equipped with a MicroMax-007 HF X-ray generator, Osmic VariMax optics, and a DECTRIS Eiger R 4 M detector at Oak Ridge National Laboratory. The data were indexed an...

This work aims to evaluate the application of optical and X-ray spectroscopy methods to determine the effect of alpha-emitting radionuclides on the properties of solid-state nuclear track detectors (SSNTD) based on nitrocellulose during their detection.
The average diameter of the nano-TiO2 crystal is 23.40 nm, obtained using the Scherrer formula: D(hkl)=KλSB×cosθDhkl=KλSB×cosθ (1) where SB is the peak broadening derived from the measured FWHM corrected for the instrumental broadening (IB); KK is the Scherrer constant, which ...
The error on the exponential attenuation factor, exp(−𝜇𝑡)exp−μt, was computed by applying the general error propagation formula to the uncertainty on thickness 𝑡t [72]. It is also important to note that the 2D-KXRF model Sr Kβ values for LB and LBOL samples are not the...
Finally, it is important to consider that in such an application the objective is to obtain an estimate of the order of magnitude of the thickness of a sample, such as tens or hundreds of microns. The maps show that the simple correlation from the Lambert–Beer law can provide meaningful ...
