Abstract: An oil-in-water nanoemulsion is provided. The nanoemulsion contains 8-12% w/v essential oil, 1-5% w/v polysorbate 80 surfactant, 2-6% w/v glyceryl citrate/lactate/linoleate/oleate co-surfactant, and 1-5% w/v glycerol monocaprylate, type I, wherein a ratio of the surfactant and co-surfactant to essential oil is from 1:1.1 to 1:1.6. Methods of preparing the nanoemulsion and for the transdermal delivery of the nanoemulsion are also provided.

Abstract: Neutron radiation can be attenuated by a material comprising acrylonitrile butadiene styrene (ABS) filament infused with gadolinium, boron, gold, and/or cadmium. The metal-infused filaments are 3D-printed to form a sleeve or cover for gamma and/or alpha radiation detectors to shield, absorb and allow detection of neutrons that are converted to gamma and or alpha radiation. The materials can also allow discrimination between neutron and gamma and/or alpha radiation in a mixed radiation field. Boron-infused filaments also provide neutron shielding and can be used in the manufacture of water equivalent phantoms.
