Different approaches to increase the storage capacity of flash memories
Researchers are investigating different ways to increase the storage capacity of the computer storage chips called flash memories.
Boosting Memory Chips
In each generation cycle memory chips get smaller and less expensive, but can hold more data. They are used in USB memory sticks, personal computers, video consoles and many other electronic devices.
The latest developments in nanotechnology for solar energy
A researcher who is using nanotechnology on the active layer of organic solar cells is Dr.
The achievement of making an object totally invisible could speed things up
One of the brains behind the invisible cloak is Professor Sir John Pendry at Imperial College London. “The cloak design has been around since 2006 when David Smith and I published our paper, but the first implementations were for radar waves.
New nanomaterials unlock new electronic and energy technologies
The collaborative* international research led by the Centre for Research on Adaptive Nanostructures and Nanodevices (CRANN), Trinity College Dublin, Ireland, and the University of Oxford has been published in this week's Science.
What changes will nanoelectronics
bring to our lives?
In nanoelectronics , miniaturised electronic circuits are integrated on semiconductor chips where the basic element is the transistor. The size of the transistors produced is under 100 nm.
Nanoparticles in our cities: any risks for our health?
Dr. Anne Beeldens and colleagues at the Belgian Road Research Centre have tested air purification efficiency by TiO2 NP-containing pavement blocks on parking lanes in Antwerp.
How do nanoparticles impact our environment and us?
In the young nanoecotoxicology field researchers such as Dr. Irina Blinova and colleagues at the National Institute of Chemical Physics and Biophysics in Estonia evaluate nanoparticles’ (NPs) interaction with their environment.
How have NGOs responded to nanomaterials’ potential toxic effects?
Non-governmental organizations around the world share concern for finding nanomaterials with potential harmful effects in stores. Research shows different nanomaterials cause injures to animal models and it is unclear what the effects would be on humans.
youris.com meets Peter Agre
In February 2009, Peter Agre was inducted as the 163rd president of the American Association for the Advancement of Science (AAAS), the nation's largest scientific organization.
Dr. Ndeke Musee: “To protect our environment we need to understand nanotechnology risks because today’s nanoproducts will be tomorrow’s waste streams”
What are the potential new types of challenges nanowastes may pose to current legislative and waste management systems? The current legislative frameworks for any country worldwide do not take into account nanowastes.
Could nanoparticles in cosmetics be toxic?
NPs in cosmetics are especially used as UV filters in sunscreens. Nano-sized titanium dioxide (TiO2) and zinc oxide (ZnO) have been widely used for years.
Uncertainties surrounding nanoparticles aimed for medical use
Researchers are trying to find out more about the relationship between different NPs’ shapes, sizes and surface chemistries and how they behave in the human body.
Peter Agre, 2003 Nobel Prize of Chemistry winner, “The generation of pure water is theoretical possible with the aquaporins”
When did you choose to do research? Somewhere is I think, research choose me. I was a student in medicine at Johns Hopkins back in the 1979th hoping to do some research relevant to the diseases of the third world.
Nano Filtered Water
The filter could be used to recycle sewage on a space station, but the main focus is the use of ultra pure water in the fabrication of semiconductors.
Pushing the efficiency limit of solar cells further
Some laboratories have achieved impressive efficiencies under concentrated sunlight. SunPower Corp. is much closer to the market. The California-based company recently produced a record-setting 24.
The Magic Touch
The “ nano wrap ” that is being developed to be fitted around an amputee’s upper arm nerve bundle is the ambitious other part of the Smarthand’s robotic hand project.
