SmB6 has recently been predicted to be a Topological Kondo Insulator, the first strongly correlated heavy fermion material to exhibit topological surface states. High quality crystals are necessary to investigate the topological properties of this material. Single crystal growth of the rare earth hexaboride, SmB6, has been carried out by the floating zone technique using a high power xenon arc lamp image furnace. Large, high quality single-crystals are obtained by this technique. The crystals produced by the floating zone technique are free of contamination from flux materials and have been characterised by resistivity and magnetisation measurements. These crystals are ideally suited for the investigation of both the surface and bulk properties of SmB6.

Background: Clinical trial sponsors rely on research sites to identify and enroll appropriate study participants and to correctly and reliably assess symptom severity and function over the course of the trial. Low-recruiting sites represent a large financial and operational burden and may negatively impact trial success either by selecting inappropriate participants and/or high prevalence of data quality issues. We previously reported that >60% of sites in schizophrenia clinical trials recruited ≤5 participants.

Background: Alzheimer's Disease (AD) poses a substantial global health burden, necessitating innovative therapeutic strategies. This study investigates the neuroprotective potential of a chrysin-loaded Nanostructured Lipid Carrier (NLC) drug delivery system in AD management. Employing the high-pressure homogenization method, chrysin-loaded NLCs were meticulously formulated to optimize drug delivery efficiency.

Faculty of Health, Australian Research Centre in Complementary and Integrative Medicine, University of Technology Sydney, Ultimo, NSW, 2007, NSW, Australia.
Background: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the impairment of cognitive development and disruption of neurocognitive function. This neuropathological condition is marked by neurodegeneration, loss of neural tissue, and the formation of neurofibrillary tangles and Aβ plaques. Various studies reported the utilization of phytoconstituents like fisetin, quercetin, berberine, and xanthohumol for the treatment of AD.
