Nano Technology

Solar energy is one of the so-called green energy or clean energy, not being a finite resource. This has produced since it was discovered that the sun could be used as a source of electricity, has been relentless in pursuit of research panels get ever higher yields and lower costs.

History of the photovoltaic panels

Photovoltaic cells, act according to the known photoelectric effect discovered by Heinrich Hertz in 1887, and theoretically explained by Albert Einstein in 1905, which earned him the Nobel Prize for Physics in 1921. Read the rest of this entry »

When speaking in terms of electronics is inevitable association with the solid state, ie, pure materials (such as those formed by elements of group IVA of the periodic table) or compounds (formed by the combination of two elements Groups III-V, II-VI …) crystal whose atoms are ideally arranged to form periodic structures and rigid. During the past five decades, the field has been remarkable progress driven by the desire to decrease the size of electronic devices, which not only lowers its price but allows the expansion of profits due to the use of effects that only occur in small scale.

All this development has been and is closely related both to the methods of observation and measurement (and their respective developments) and the methods of synthesis of these nanoscale devices or directly submicron which imposes limitations on the study of these materials.

This article is a very interesting electronic material: graphene.

The experimental discovery of this two dimensional array of carbon atoms in 2004 by Konstantin Novoselov and Andre Geim, has yielded not only a Nobel Prize to these two young scientists, but to dream the scientific world with new electronic applications at scale small as possible.

According to the findings of two recent reports on nanotoxicology, most studies in the last ten years have focused primarily on the application of nanomaterials in place of their risk to human health and the environment.

But why should the lack of studies of risk to human health and the environment? Everything points to the lack of availability of experts in the field.

This reminds me of the productive vision that strives to provide the materials engineer today: ” you must be capable of solving problems, meeting needs through the manufacture and design of new materials or improve existing ones “told me a professor of materials in recent years.

Most of the contributions of this blog are intended to review progress in nanotechnology “dry.” There are directed most research in nanostructured materials, quantum computing, superconductors and other advances that we will make life easier in the following decades, generally applied to materials for use “outside” as a circuit, a transistor or a material with specific properties. However, there is another form of nanotechnology closer to biology: wet nanotechnology. Using different components, instead of carbon nanotubes or fullerenes, using materials that are millions of years and running self-assembled nanoscale within us all: the peptides (including longer peptides such as proteins) and nucleic acids, DNA and RNA.

Speaking of energy storage systems that can be used later to run devices, we usually think in batteries that store electrical energy, such as laptops that run or driving electric cars. But there is another form of energy that might not usually think much for that purpose, let alone if we want to relate to nanotechnology: the mechanical energy.
An example would be stored in a spring of a watch from those to which must be wound, although not many left. Another, traps for mice or, more ancient catapults that sent large rocks with sufficient energy to destroy the defensive ramparts and medieval antiquity. Read the rest of this entry »

Nanotechnology has accustomed us to infinite progress in many technological improvements, but also the technology is also applicable to the field of nutrition. In this field, allow improving the quality of the products consumed in our diet. As a result the European Commission is studying how to achieve effective regulation to ensure safety, reliability and quality of products coming into our markets.

Nanotechnology industry expects to improve such food manipulation getting flavors, potentiated or replaced, as, for example, that a food containing an unsweetened flavor without resorting to sugar sweeteners, and therefore, improving quality of life of many diabetics. This can be achieved by nanocapsules , which get to the diet have an enhanced flavor and may, thus, replacing cholesterol. Read the rest of this entry »

As always explain nanotechnology has reached all the stages of our lives and every day goes on acquiring new form. In the textile sector is also present and has invented a type of tissue with nanoparticles that is able to repel coffee, wine etc., Ie, they invented the clothes are not dirty, these tissues are not only great progress in that do not become soiled but also revolutionary when bacteria, viruses, etc.., as it may even be able to repel them.

Within tissue types and forms there for leather and other textiles has invented a liquid that if we spread this type of tissue makes them impervious both fat and aqueous fluids is called ‘Percenta Nano Leather lining and textiles “with this type of solution elements and fatty liquids to fall away because this solution are absorbed slowly, how favorable this solution has is that it is not aggressive to textiles used, ie the skin and other elements which are used intact, do not alter any of this.

Since the discovery of carbon nanotubes (CNT), they are presented as the future replacement of conventional semiconductor materials in integrated circuits due to their high electrical and thermal properties. The mean free path of electrons in certain directions of a graphene layer can be very large and if the nanotube chirality is optimal, the electrons may traverse from one end to another with little resistance. This is what is called ballistic conduction occurs when the length of the nanotube is around or less than the mean free path of electrons or holes. Fortunately, for the CNT that is readily available and hence their interest in the technology industry.

However, despite its nearly ideal properties, its application is not as immediate as it seems. One of them is in the same device structure of a FET (field effect transistor) and has to do with the coating of the CNT. Read the rest of this entry »

For some years microelectronic structures are becoming smaller to achieve higher performance at lower cost. Nanoelectronics is an element of electronics that deals with the development and production of miniaturized circuits. Nano stands for the unit of length nm, which deals with this line of research.

The transition between micro-and nano-electronics is still flowing, there is no strict boundary between the two areas, so there is often overlap. Currently, a structure falls below the size of 100 nanometers in the area attributed to the nano-electronics. Read the rest of this entry »
