Item Open Access Breast cancer at the micrometre scale(Cranfield University, 2020-11-27 09:28) Gosling, SarahMicrocalcifications are deposits of calcium phosphate commonly found in association with some types of breast cancer. Calcifications are usually detected as bright white spots on a mammogram. Diagnosis of some breast diseases is linked to the morphology and distribution of microcalcifications, but these deposits are rarely investigated as individual entities.Multiple techniques have been used to investigate individual calcifications, including histological staining (H&E), scanning electron microscopy (SEM), elemental analysis (EDS) and x-ray diffraction (XRD). Together, these techniques allow a better understanding of the structure of the crystalline and tissue elements of breast calcifications at the micrometre scale, which may provide an insight in their formation mechanisms and possible functions. Ultimately, deciphering calcification chemistry could lead to their use as novel prognostic markers for breast disease.Item Open Access Capturing blast impact on helmets(Cranfield University, 2020-11-27 10:21) Bloodworth-Race, SusieWhen shielded from the fireball and fragmentation of an explosion, the blastwave can still cause multiple injuries, with increasing prevalence of Traumatic Brain Injury (TBI) noticed amongst survivors. Relatively low peak overpressures can result in Blast-Induced Mild TBI (bTBI), with significant deterioration in mental health manifesting as anxiety, behavioural changes, even loss of fine motor control, symptoms which can often be confused with Post Traumatic Stress Disorder (PTSD).The image shows a helmet blast impact from a compressed air shocktube, the resulting movement of head and helmet captured with high speed video. The moment of impact can be seen in the top sector with the shockwave captured as a vertical band of compressed air just behind the front of the head. The helmet is lifted, rotated backwards, held by the chinstrap and bounced back down onto the head, resulting in multiple possible mechanisms for bTBI.Item Open Access Reflections and Their Real Space Significance(Cranfield University, 2020-11-27 10:01) Arnold, EmilyBone is a complex composite material made up of three main components, the most abundant of which is the mineral hydroxyapatite. Within many species, hydroxyapatite naturally occurs as a nanocrystalline material, making accurate analysis difficult. Brilliant X-ray sources are used to allow measurement of a much wider range of angular data (from Q = 0.05 to 60 Å-1) than a traditional laboratory X-ray diffractometer (from Q = 0.1 to 8 Å-1). Shown here is diffraction data collected at Diamond Light Source on the dedicated total scattering beamline I15-1. Debye-Scherrer rings can be seen, allowing measurement of crystallographic parameters within reciprocal space. Shadows are seen from the sample changer and an additional detector. This beamline allows for the observation of local coordination of atoms from 0.1nm to 5 nm (through pair distribution function analysis) while simultaneously measuring average crystallite structure.Item Open Access Structure of an Insensitive High Explosive formulation under a microscope(Cranfield University, 2020-11-27 10:07) Gutierrez Carazo, EncinaIMX-104 is an Insensitive High Explosive containing a mixture of 3-Nitro-1,2,4-triazol-5-one (NTO), 2,4- dinitroanisole (DNAN) and cyclotrimethylenetrinitramine (RDX). Due to its novelty, little is known about its potential toxicity and persistence in the environment and which has raised questions regarding its behaviour.Small flakes were placed under a Leica DM LM microscope to observe their microscopic structure and investigate the formulation process. The picture was taken using a ten times lense (10x) and reflected light. The scale shows the size of the flakes (in mm) and the fragments in focus were approximately 70 µm.
