Nanotechnology and Manufacturing
Four years ago, words like “impossible,” “futuristic,” and “science fiction” filled discussions about nanotechnology. Since the announcement of the US National Nanotechnology Initiative in 2000, though, worldwide investment in nano research and development has raced forward, with $8 billion invested in 2004 alone. That kind of growth has leaders at major companies sitting up and [...]
Nanotechnology with Carbon Nanotubes
Columns, pipes, bearings and springs are a few common ways that engineers have made use of the geometric shape known as a ‘cylinder.’ The utility of this shape is apparent in architecture, plumbing and mechanical devices. Carbon nanotubes are molecular cylinders that are rapidly extending our ability to fabricate nanoscale devices by providing molecular probes, [...]
balancing risk and opportunity
The challenge with all emerging liabilities is to identify risk potentialities at an early stage, and well before they become the subject of court action. Technology is no exception and with rapid innovation companies can find it difficult to keep up with the risks. Nanotechnology is a good example. And it’s one where you get [...]
NANOTECHNOLOGY INTRODUCTION
Truly revolutionary nanotechnology products, materials and applications, such as nanorobotics, are years in the future (some say only a few years; some say many years). What qualifies as “nanotechnology” today is basic research and development that is happening in laboratories all over the world. “Nanotechnology” products that are on the market today are mostly gradually [...]
Nanotechnology for Sustainable Economy
The EuroNanoForum 2009 international nanotechnology conference took place from 2nd to 5th June 2009 in the Prague Congress Centre, organized by the Technology Centre of the Academy of Sciences of the Czech Republic, as an event of the Czech Presidency and under the auspices of the Czech Ministry for Education Youth and Sports. It has [...]
Industrial nanotechnology processes getting closer
For years now, nanotechnology researchers have been promising us carbon nanotubes as the basis for numerous breakthrough applications such as multifunctional high-strength fibres, coatings and transparent conducting films. Not to mention as a cure for cancer (see“Horseradish, carbon nanotubes and cancer therapy”) and a solution to the energy crisis. However, while the thermal, electrical and [...]
Sharper and faster nanodarts kill more bacteria
A newly published antibacterial activity mechanism study demonstrates how a single walled carbon nanotube (SWCNT) kills bacteria by the physical puncture of bacterial membranes. The nanotubes would constantly attack the bacteria in solution, degrading the bacterial cell integrity and causing the cell death. This work elucidates several factors controlling the antibacterial activity of pristine SWCNTs [...]
