Apple iPhone apps put Nanotechnology in your pocket

The Project on Emerging Nanotechnologies (PEN), established in April 2005 as a partnership between the Woodrow Wilson International Center for Scholars and the Pew Charitable Trusts (Washington) has developed findNano, an application for Apple’s iPhone and iPod Touch that lets users discover and determine whether consumer products are nanotechnology-enabled ranging more than 1,000 different products from consumer electronics, toys or food to improved drug delivery systems.

This application takes as base, the PEN’s “Consumer Products Inventory”, which is one of the leading sources of information on manufacturer-identified nanotechnology consumer products around the world and through this new application becomes more accessible for today’s consumers.

Patrick Polischuk, Research Associate at PEN says: “This innovative tool satisfies the needs of citizen, scientists, tech-savvy consumers, and those who are merely curious about whether products contain nanomaterials.”

To help develop better estimates of the number of nano-based products in commerce, the iPhone app allows users to submit information on new products, including product name and where the product can be purchased. Using the built-in camera, iPhone users can even submit new nanotech product to be included in future inventory updates. This feature will help consumers, researchers, etc to determine how and where nanotechnologies are entering the marketplace.

findNano is available as a free download for the iPhone and iPod Touch, and can be found in the iTunes App Store.

A California startup called Amprius sells a new type of anode for lithium-ion batteries. These anodes are made from silicon nanowires.

According to the company, this anode will provide more autonomy to both electric vehicles as mobile devices, allowing storing a charge 10 times higher than that of graphite, which is currently used.

The startup of Ithaca, Orthogonal, is developing materials that will enable organic electronic components using the same type of equipment used to manufacture silicon electronic components, allowing the construction of more complex organic compounds also.

The company has made four prototype devices using new photolithography chemical compounds compatible with organic materials.

In the company’s website we can also find a flash resource that explains the OLEDs operation that may be useful as an educational resource.

Solar Energy Backpacks to Recharge Electronic Devices

Mascotte Industrial Associates has submitted a new backpack that incorporates thin film solar cells dye sensitized. These backpacks are lined with layers of this type of solar cells which are flexible, lightweight, and low cost and they will recharge electronic devices as we move. With these packs we could recharge the phone without needing a nearby power point.

The solar cells manufactured by G24 Innovations, are based on semiconductor nanocrystals coated with a layer of dye. The dye absorbs light and creates electrons which are transmitted to the semiconductor and then to the circuit.

These solar cells have a lower efficiency than the best thin film solar cells but they have in advantage that they are significantly cheaper and they can be printed on flexible surfaces.

In addition, dye-based cells operate in a wide range of angles; they have a long durability and they are effective indoors, because the dye is poorly absorbed by diffuse sunlight and fluorescent light.

Conductive Inks

The american startup Vorbeck Materials hopes to market, later this year, grafene-based conductive inks that could be used to print RFID (Radio Frequency Identification) antennas and contacts for flexible displays.

According to the company, these graphene-based inks can be used in applications where traditional inks based on carbon do not reach sufficient conductivity and with a price significantly lower than silver inks.

Nanotubes for X-Ray Machine

The company Xintek, a spin-off from the University of North California at Chapel Hill, has partnered with Siemens Medical Solutions to form a company, XinRay Systems, which has developed a prototype for producing X-rays from carbon nanotubes.

The conventional X-ray machines use a single emitter of tungsten as electron emitter, while the prototype developed by XinRay Systems uses a series of vertical carbon nanotubes, providing hundreds of small issuers.

Meanwhile, in conventional machines, it takes a while to heat the tungsten; the nanotubes emit electrons instantly when subjected to voltage. Furthermore, conventional technology requires the source of electrons moving around the object to obtain 3-D (as in CT) and need to take hundreds of images because the motion of the heart and lungs can lead to blurred images. The machine developed by XinRay Systems can turn on and off multiple nanotubes issuers, and this facilitates additional sequential images from different angles.

It has been shown that this new technology accelerates the body imaging; the images obtained are sharp and could increase the precision of radiation therapy so as not to damage healthy tissues.

The company Xintek sells its nanotube emitter display technology to manufacturers like Samsung and Motorola, which use them for the development of screens that consume less power than LCD and plasma while maintaining the same resolution as the cathode ray.

A group of researchers from the Basque technological centre CIDETEC-IK4, the Centro Superior de Investigaciones Científicas (CSIC) and University of Berkeley have developed highly sensitive electrochemical sensors to detect possible mutations in the DNA faster than it was to moment.

These nanosensors use a single nanotransistor which cable is a simply carbon nanotube and allow the development of optical and electrochemical nanosensors, enabling the detection of DNA probes without the need for modification to increase the sensitivity of the system.

In the future, these nanosensors could be used to detect other molecules, and for studies of genetic diseases.

A major constraint in the development of organic devices is the use of indium tin oxide as bottom electrode, because it is expensive, low, means high temperature process, polymer degradation and leads to ways to lower the optical out-coupling efficiency of the device.

To solve these problems, researchers at the Institute of Photonic Sciences (ICFO) are working on the possibility of using thin nickel layer in place of indium tin oxide as anode for bottom-emitting organic light-emitting diodes.
