The nanoFate Model Assesses the Risk of Engineered Nanomaterials in the Environment

Press Releases

While there is currently no evidence that engineered nanomaterials (ENMs) pose a significant threat to the environment, many gaps in our knowledge remain with regard to ENM ecotoxicity. The lack of evidence should by no means be interpreted to imply that environmental damage cannot occur (read more: Nanotechnology and the environment – Hazard potentials and risks)...

Better Living Through Pressure: Functional Nanomaterials Made Easy

Press Releases

Using pressure instead of chemicals, a Sandia National Laboratories team has fabricated nanoparticles into nanowire-array structures similar to those that underlie the surfaces of touch-screens for sensors, computers, phones and TVs. The pressure-based fabrication process takes nanoseconds. Chemistry-based industrial techniques take hours...

All-Printed Thin-Film Transistors from Networks of Liquid-Exfoliated Nanosheets

Press Releases

Researchers in AMBER, the Science Foundation Ireland-funded materials science research centre hosted in Trinity College Dublin, have fabricated printed transistors consisting entirely of 2-dimensional nanomaterials for the first time. These 2D materials combine exciting electronic properties with the potential for low-cost production...

Carbon Nanotubes Self-Assemble into Tiny Transistors

Press Releases

Carbon nanotubes can be used to make very small electronic devices, but they are difficult to handle. University of Groningen scientists, together with colleagues from the University of Wuppertal and IBM Zurich, have developed a method to select semiconducting nanotubes from a solution and make them self-assemble on a circuit of gold electrodes...
