All about Nanotechnology

Nanotechnology talks about widely to a field of science and the technology applied that subject of the unification is the control of the matter in the atomic and molecular scale, normally 1 to 100 nanometers, and to the manufacture of devices with the dimensions critics that lie with in that range of the size.

It is a highly multidisciplinary field, drawing of fields such as science of the applied physics, of material science, the interface and the colloid, physics of the device, the supramolecular chemistry (that refers the area of the chemistry that is centered in the non-covalent interactions of the molecule entailment), one same-folding the machines and robotics, chemical engineering, industrial engineering, biological engineering, and electrical engineering. Much speculation exists as far as what it can be from these lines of the investigation. Nanotechnology can be seen like extension of existing sciences in nanoscale, or like modification of existing sciences using newer, more modern term.

Two main approaches are used in nanotechnology. In the approach “bottom-up”, the materials and the devices are constructed of the molecular components that mount chemically by principles of the molecular recognition. In the approach “of above downwards”, the nano-objects are constructed of greater organizations without control of the atomic-level. The impetus for nanotechnology comes from an interest renewed in the science of the interface and the colloid, joined with a new generation of analytical tools such as atomic force microscope (AFM), and scanning tunneling microscope (STM). Combined with refined processes such as electron beam lithography and molecular beam epitaxy, these instruments allow the deliberate manipulation of nanostructures, and led to the observation of novel phenomena. The examples of nanotechnology in modern use are the manufacture of polymers based on the molecular structure, and the design of the dispositions of the shaving of computer based on superficial science Despite the great promise of numerous nanotechnologies such as quantum dots and nanotubes, real commercial applications have mostly used the advantages of colloidal nanoparticles in bulk form, such as suntan lotion, cosmetics, protective coatings, drug delivery, and stain resistant clothing.

Who Is Not Enjoying Their Christmas?

There are many people who use Christmas in spreading controversies. They don’t like to enjoy the holiday and don’t allow others to enjoy it.

And when this group of people waged a war on Christmas, it became the Christmas Controversy. They kept on raising issues over issues on Christmas and always turned down the holiday mood of people who wanted to enjoy it.

Their first achievement was to ban the word Christmas from mentioning on December 25th by government or corporate or the public.

And even they banned using the word Christmas tree in public and now they call it as Holiday tree.

And the vows of giant retailers are different. First it was Sears Corporation that had to alter all their marketing campaigns with the word Christmas for the word Holiday.

Similar retailers are Wal-Mart, Target Corp, Gap Inc, Best Buy Corp, etc.

But you don’t have to get disturbed with all these thongs. Controversy or no controversy, celebrations remain the same for us.

How to Prevent Hair Loss?

Having hair loss is the very shocking experience for everyone all over the world. But if you take the some prevention steps you can prevent our hair loss problem. But you need proper dedication towards a hair care. Keep in mind that a regular hair care helps address your hair loss problem easily and efficiently. Here are some prevention tips to loss hair loss:

  • The first thing in preventing hair loss is to follow a healthy balanced diet. Try to maintain a healthy diet helps in keeping the energy levels that are essential for the body to manage health issues such as hair loss prevention.
  • Try to have the good diet such as cereals and milk contain high levels of vitamin A.
  • Try to use fresh fruits, vegetables, dairy products, nuts, almonds, coconut, poultry, fish, eggs makes the hair look soft and shiny. Fish is a good source of vitamin B12 that helps maintain oil in the hair and skin so that the hair doesn’t dry and die.
  • Try to avoid of tea and coffee because it destroys the excretory system of the body..
  • Try to avoid alcohol consumption, as alcohol increases the excretion of essential nutrients and water. Because alcohol is aggressive to the proteins, minerals and vitamins that are essential for maintaining healthy hair.
  • Exercise is another good hair loss prevention measure. It helps control blood circulation and gives strength to the hair. Remember that proper blood flow and good supply of oxygen makes the hair to use the diet correctly.
  • Try to select shampoo, conditioner, spray, gel, color, and oil that are suitable to your hair type.

Once you follow a healthy diet, exercise routine and good sleep makes the hair strong and healthy from inside and taking care of the hair appearance from outside becomes very easy.
