DESCRIPTION:Speakers: Meltem Bayrak ()\nFor various soft and hard matter s
 ystems\, reduction in sample particle size could be an effective method fo
 r producing homogeneous samples\, eliminating trapped air bubbles\, facili
 tating sample preparation (e.g.\, gel loading)\, or meeting the requiremen
 ts of a specific sample environment. Due to the experimental constraints o
 f small-angle scattering\, such as the limited width (1 or 2 mm) of the sa
 mple cell\, time-dependent characterisation of larger samples in real time
  is often not possible.  Physical disruption of samples into smaller sized
  particles at a macro scale would allow simultaneous characterisation of a
  variety of systems\, such as facilitating the flow of polymers\, gels\, a
 ggregates\, and minerals. While physical crushing or blending may appear t
 o be a straightforward solution to the problem\, a lack of knowledge about
  the effect on the nano- and microstructure precludes its widespread adopt
 ion.\n\nIn this study\, a yoghurt-like transglutaminase-induced acid gel (
 TG)\, was blended as a method of disruption\, allowing the gel particles t
 o flow freely in the newly developed recirculated flow set-up designed for
  the *in situ* analysis of gel devolution over time. The study has demonst
 rated that mechanical disruption to form TG particle distributions within 
 the 5-6 µm to ~3.5 mm size range had no effect on the micro- and nanostru
 cture of the gel. This work could benefit several studies\, including dyna
 mics of hydrogel swelling\, characterisation of particles in motion\, dige
 stion or changes in structure when exposed to different environmental cond
 itions\, as well as the implementation of newly developed setups in severa
 l neutron scattering studies.\n\nhttps://events01.synchrotron.org.au/event
