Health and Safety Screening of Advanced Materials: A User Interface for Test Design Selection and Documentation

Kennedy A.J., Brame J., Wood M., Rycroft T., Poda A., Diamond S., Chappell M., Shih W-S, Panchal V., US Army Engineer Research and Development Center, US

The novel properties of advanced materials (AdMs), including nanomaterials (NMs), offer opportunities to improve conventional materials and create new material applications. However, these same properties may place AdMs into a high risk prioritization category within [...]

Quantifying release of nano- and advanced materials

Brame J., Poda A., Alberts E., Jackson C., Kennedy A., US Army Engineer Research and Development Center, US

The same unique properties of Manufactured Nanomaterials (MNs) and Advanced Materials (AMs) that make them desirable for new product applications may also increase their environmental health and safety (EHS) uncertainty , leading to high risk [...]

Developing a fundamental understanding of polymer nanocomposite photodegradation and CNT release characteristics

Lankone R.S., Wang J., Ranville J.F., Fairbrother D.H., John's Hopkins University, US

As the development, production, and use of polymer nanocomposites continues to rise, so too does the likelihood for exposure of their embedded nanoparticles to humans and the environment following nanoparticle release. The release of carbon [...]

Enhanced in vitro testing model for rapid risk assessment of ingested nanomaterials

Carnovale C., Guarnieri D., De Angelis I., Barone F., Sabella S., Italian Institute of Technology, IT

Following advances in the synthesis of manufactured nanomaterials, interest for their inclusion in various consumer products has increased. Due to various factors including their unique optical and antimicrobial properties, likely applications of nanomaterials include textiles, [...]

Nanomaterials in Food and Food Contact Substances – Hazards, Risks and Regulation

Cohen J., Gradient, US

The increasing number and variety of engineered nanomaterials (ENMs) used in food and food contact materials raise concerns regarding potential hazards and risks to human health. ENMs are used for a wide variety of applications [...]

Nanotechnology Regulation Implementation in Industry

Taylor A.A., Freeman E.L., Exponent, Inc., US

Nanotechnology is a fast growing industry with increasing applications in consumer, industrial, pharmaceutical, and personal care products. One issue facing the nanotechnology sector is that current chemical regulations focus on single chemical substances and do [...]

An integrated methodology across the dispersion preparation-characterization-in vitro dosimetry continuum for engineered nanomaterials

Cohen J., DeLoid G., Pirela S., Pyrgiotakis G., Demokritou P., Harvard School of Public Health, US

Evidence continues to grow of the importance of in vitro and in vivo dosimetry in the hazard assessment and ranking of engineered nanomaterials (ENMs). Accurate dose metrics are particularly important for in vitro cellular screening [...]

Protecting the nanotechnology workforce: a new protocol for characterization of filter-captured nanomaterials from occupational exposure assessments

Neu-Baker N., Smith D., Segrave A., Beach J., Zurbenko I., Dunn K., Brenner S., SUNY Polytechnic Institute Colleges of Nanoscale Science & Engineering, US

The nanotechnology workforce is growing along with the rapid commercialization of nanotechnology, with an estimated 6 million workers by 2020;1 however, risk assessment for nanotechnology workers is still in its infancy because occupational exposure assessment [...]

The Key Technologies of Laser Surface Texturing and the Relative Equipments

Fu H., Fu Y., Fu H., Fu Y., Hua X., Ji J., Ye Y., Kang Z., Chen T., Jiangsu University, CN

Recently, there are three challenges of engineering practices of surface texturing for the diversity of geometrical shapes and complex operating conditions of mechanical components, such as optimal design, machining and equipment. Our group has always [...]

Anisotropic Wetting Behaviour of Modified 3D Printed Micro-Structured Polymer Surfaces for Water Harvesting

Cook M.J., Johnston J.H., Leveneur J., Victoria University of Wellington, NZ

We present an attractive new technology for the design and fabrication of micro-structured water harvesting surfaces through a unique combination of 3D printing and hydrophilic/hydrophobic surface modification. For many years, researchers have examined the wetting [...]
