Be the smallest accelerometer in the world: new possibilities for wearables
Wearable or wearable devices such as activity monitors are a good example of the Internet of things, since things like electronics, software, sensors and connectivity are mechanisms that allow objects to exchange information over the Internet with a manufacturer, operator or other connected devices.

The video that you can see next, be this more or less spectacular, contains data to develop new and better energy conversion materials. And it is that in it we can see, at the atomic level and in real time, how nanoparticles are formed, monitoring the rearrangement of atoms in real time using electronic scanning microscopy with scanning corrected for aberration.
Graphene could increase high speed communications
Graphene could increase high speed communications
Communications could be faster thanks to the discovery of a new technology that has shown how electric fields increase the nonlinear optical effects of graphene. The results have been published in the journal Nature Nanotechnology. Due to a physical phenomenon called the generation of optical harmonics, which is characteristic of non-linear materials, graphene has the property of capturing photons combining them and producing a more powerful optical beam.

A group of scientists from India and the University of Swansea in the United Kingdom have recently discovered that nanoparticles derived from tea leaves ## can inhibit and destroy lung cancer cells. The finding, like many of the best scientific discoveries, happened casually.
This is the smallest house in the world and has been robotically assembled.
This is the smallest house in the world and has been robotically assembled.
A nanometric house built on the face of an optical fiber has been assembled by a micro-robotics system developed by nano-robotics researchers from the Femto-ST Institute. Specifically, the tile roof of this house, the smallest in the world, shows the new capacity of the Robotex nanofactor ion gun to focus on an area of ​​300 by 300 micrometers.
The smallest flag ever conceived
The smallest flag ever conceived
A flag is much more than a piece of painted rag for many people. The flags, for some, are indelible marks at the sociological level. And they can also be icons to experiment with them, both for their psychological influences, and even to address physical challenges. As the creation of the smallest flag in the world.

Tumors are located and destroyed in just 48 hours thanks to this nanobot
At Harvard, Shawn M. Douglas has also created a molecular-sized robot that sends drugs to specific cells. It is only the tip of the iceberg, not surprisingly nanotechnology is one of the fastest growing branches of science. In 2009, the global nanotechnology market billed 11.
In this car race the distances are less than 100 nanometers
In this car race the distances are less than 100 nanometers
This is the first nanocar race in the world and will be held in a Tolouse laboratory on April 28. The race, with cars that cannot be seen with the naked eye, will be organized by the National Center for Scientific Research (CNRS). In addition, the distance of the race will be only 100 nanometers.

China has built the world's largest nanoscience facility
In order to develop more powerful computers and smarter robots, China has built Nano-X, the world's largest multifunctional research facility for nanoscience and nanotechnology. The Vacuum Interconnected Nano-X Research Facility is specifically located in Suzhou, Jiangsu Province.
This electric cable is the finest in the world: three atoms thick
This electric cable is the finest in the world: three atoms thick
An electric cable as thin as three atoms thick and made up of diamond particles has just been developed by scientists at Stanford University and the SLAC accelerator. It can be used to create LEDs with few atoms and small piezoelectric generators. The technique to create them takes advantage of the so-called van der Waals forces, which in this case cause the diamond molecules to attract each other to form larger crystals.
The color of the blue tarantula has been mimicked with nanotechnology
The color of the blue tarantula has been mimicked with nanotechnology
The blue tarantula (Poecilotheria metallica) has a very striking coloration, especially in the case of males (it is formed in the same way as the wings of a butterfly or the feathers of a peacock). Now a group of scientists has managed to replicate this unique color. The international group of scientists, led by the University of Akron (United States), which has managed to replicate the color of this tarantula artificially, has published the finding in the journal Advanced Optical Materials.
For the first time in history we see the union between atoms thanks to this
For the first time in history we see the union between atoms thanks to this
The smallest magnifying glass in the world has broken the limit of light entrapment, which has allowed, for the first time in history, we can contemplate a chemical bond between two atoms, according to a recent study published in the journal Science. The development of this device, called picocavity, has been carried out by researchers from the University of Cambridge, the CSIC and the University of the Basque Country, and has thus managed to exceed the diffraction limit of the light located on the nanometer scale .

This is what happens to a worm if you feed it with graphene
Graphene, a two-dimensional material composed of carbon atoms that are organized in hexagons, is called to be one of the materials of the future to obtain all kinds of wonders. However, if we feed a worm a little graphene, we can also get something very interesting.

With this fabric you will not need to put the air conditioning
A low-cost plastic-based textile has been developed by Stanford engineers and has the ability to filter the radiation emitted by the human body, so making clothes with it we could do without, more often than not, a system of air conditioning . This new material would allow the user to feel almost 4 ° C less than with traditional cotton clothing.
All the world's literature on a label: the storage of data at atomic scale
All the world's literature on a label: the storage of data at atomic scale
Storing a kilobit (8,000 bits) representing each bit by the position of a single chlorine atom is already possible thanks to the research of scientists from the Kavli Institute of Nanoscience of the University of Delft. This storage capacity is so small that the size of a stamp would be sufficient to store all the universal literature.
