In the future hydrogen economy, nanotech-based H2 sensors will be widely needed
In the future hydrogen economy, hydrogen (H2) sensors will be a critical component for safety and widely needed. For example, H2 sensors will detect leaks from hydrogen-powered cars and fueling stations long before the gas becomes an explosive hazard.
Large-scale fabrication of integrated nanoelectronic devices moves closer
A new methodology for integrating nanowires with micropatterned substrates using directed assembly and nanoscale soldering was developed by researchers at Johns Hopkins University in Baltimore. This overcomes the difficulty in making electrical contacts to nanoparticles, which so far has been a major limitation to fabricating integrated nanoelectronic devices containing large numbers of nanoparticles.
Nanocarriers could become an alternative to brain surgery
If you had brain tumor, would you rather receive your medicine through an injection in the arm or have a hole drilled in your skull? One of the most important applications of nanotechnology could be drug delivery by nanoparticles (or nanoshells) in particular into the brain. An international group of researchers developed a novel targeted nanoparticulate drug delivery system for the brain
Hybrid carbon nanotube material allows ultrafast nonlinear optical switching
Nano Zinc Oxide (ZnO) and Carbon Nanotubes (CNTs) are arguably two of the most studied nanomaterials in recent years. Combining these two nanomaterials into hybrid nanomaterial presents a fascinating nanosystem for further investigations.
Nanoscopic medicine: the emergence of a new medical specialty
Nanoscopic medicine refers to the direct visualization, analysis (diagnosis) and modification (therapy) of nanoscopic protein machines in life cells and tissues with the aim to improve human health.
One step closer to industrial fabrication of photonic crystal devices
Researchers in the UK and Germany told Nanowerk that they developed a simple, fast and efficient method for fabricating metallic photonic crystals. This new method opens the door to a number of applications in telecommunication, all-optical switching, sensors, and semiconductor devices.
Research on nanopore materials shows potential for industrial photocatalysis applications
A novel instrument for analyzing porous nanostructures will aid the improvement of photocatalysis, which is an important application in industry, for example for water or air purification.
Nanowires could lead to improved solar cells
With an increased focus on alternative sources of cheap, abundant, clean energy, solar cells are receiving lots of attention. The dye sensitized solar cell (DSSC) is one of the most important developments in photovoltaics in the last two decades. Researchers are now on the brink of improving the efficiency of DSSC through nanowires.
