Enabling Autonomous Sensing Devices for IoT with Thin Film Batteries

Johnson G., Hayden B.E., Lee C.E., Laughman D., Noble R., Turner L., Clarke O., Casey P., Ilika Technologies, UK

Applying its heritage of patented materials invention, Ilika has developed thin-film, solid-state, Li-ion batteries to meet the specific demands of applications in the IoT space. As IoT devices become utilized across a wider range of [...]

Lattice Engineered Nanoparticles

Casey P., Rossouw C.J., Murphy A.B., Bell C., Commonwealth Scientific and Research Organisation, AU

Nano-particulate oxides such as ZnO and TiO2 are receiving much attention as functional nanoparticles predominantly due to their increased efficiency in absorbing UV at small particle sizes. However, whilst protection against UV may be maintained [...]

Stable Isotope Tracing – a way forward for Nanotechnology?

Gulson B., Wong H., McCall M., Danon S., Greenoak G., Trotter J., Casey P., Stauber J., Commonwealth Scientifc and Industrial Research Organisation, AU

Numerous publications and reports have expressed health and safety concerns about the production and use of nanoparticles, especially in areas of exposure monitoring, personal use, and environmental fate and transport. We suggest that stable isotopic [...]

Issues relating to the use of Micro and Nanoparticle Zinc Oxide in Personal Care Products based on Skin Penetration Studies

Casey P., Chau N., Finnin B., CSIRO (CMIT), AU

Nanoparticles of ZnO and TiO2 are increasingly being used as pigments and UV absorbers in personal care products (e.g. sunscreens), coatings and paints, predominantly because their UV absorbance efficiency and transparency to visible light increases [...]

Controlling the Photoactivity of Nanoparticles

Casey P., Boskovic S., Lawrence K., Turney T., CSIRO(CMIT), AU

The relative photoactivity of a series of nanophase ZnO powders with varying crystallite size (20-140nm) was determined using a chemical method based on the photobleaching behaviour of the stable radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). It was confirmed [...]
