Dynamical scattering in electron diffraction is a concern when crystals are thicker than a few hundred nanometers (Subramanian et al., 2015); still, protein structures have been determined successfully from crystals measuring up to 400 nm thick (Hattne et al., 2015).
WebObesity is a common problem in horses. The associations between obesity and equine metabolic syndrome (EMS) and between EMS and laminitis are known. However, there is a lack of data on whether obesity itself can affect hoof lamellae. Forelimbs and blood from 12 draft horses (six obese and six lean) from a slaughterhouse were acquired. To exclude …
WebIn most usual situations the lamellar crystals are in the form of multilayer assemblies. In fact, in the course of growth, single lamellae ‘multiply’ via the familiar screw dislocation … WebThe presence of thicker lamellae leads to a higher yield stress at temperatures above the glass transition temperature where the contribution of crystals to the yield stress is higher. On the other hand, with thicker lamellae, the critical stress for voids formations is exceeded before the crystal can deform plastically [ 33 ].
