Nanotechnology's contribution to reconstructive surgery

To rebuild damaged parts of a human body from scratch is a dream that has long fired human imagination, from Mary Shelley's Doctor Frankenstein to modern day surgeons. Now, a team of European scientists, working in the frame of the EUREKA project ModPolEUV, has made a promising contribution to reconstructive surgery thanks to an original multidisciplinary approach matching cutting-edge medicine to the latest developments in nanotechnology.

Butterfly wings behind anti-counterfeiting nanotechnology

Imagine a hole so small that air can't go through it, or a hole so small it can trap a single wavelength of light. Nanotech Security Corp., with the help of Simon Fraser University researchers, is using this type of nanotechnology to create unique anti-counterfeiting security features.

Electron gas on the surface of an insulator opens the way to multifunctional transistors

Researchers at CNRS and Universite Paris-Sud 11 have succeeded in creating a conductive layer on the surface of strontium titanate (SrTiO3), a transparent insulating material considered to be very promising for the development of future microelectronics applications. Two nanometers thick, this conductive layer is a two-dimensional metallic electron gas (2DEG) that is part of the insulating material.

Controlled heating of gold nanoparticles

Tiny gold particles are good for transferring heat and could be a promising tool for creating localized heating in, for example, a living cell. In new experiments, researchers at the Niels Bohr Institute have measured the temperature of nano-sized gold particles with extreme precision and have examined their ability to melt the lipid membranes surrounding cells, paving the way for dissolving sick cells.

A first look at flight in 2025

An 18-month NASA research effort to visualize the passenger airplanes of the future has produced some ideas that at first glance may appear to be old fashioned. Instead of exotic new designs seemingly borrowed from science fiction, familiar shapes - but built with high-tech materials - dominate the pages of advanced concept studies.
