The wide application of nanotechnology

Nanometer and meters, micrometers and other units, is a unit of length, and a nanometer is equal to ten-nine meters, about an order of magnitude than chemical bonds grew up. Nanotechnology is the study by between 0.1 and 100 nm in size the system motion laws of matter and interactions as well as possible technical problems in the practical application of science and technology. Can be derived from nano-electronics, mechanical, biological, materials processing and so on.

Nano-materials refers to at least three dimensional spatial scale of one-dimensional nanoscale materials, it is made between the size of atoms, molecules and the macroscopic system of next-generation materials composed of nanoparticles. Due to its small scale units, interface takes up a fair amount of ingredients. Therefore, nano-materials with a variety of features, which lead to different system of nano-particles from mostly large chunks of the macro-system of many of the special nature of the material. Nano system makes people awareness natural and entered a new of levels, it is contact Atomic, and molecular and macro system of link, is people past never exploration had of new field, actually by nano particles composition of material to macro system evolution process in the, in structure Shang ordered degrees of changes, in State Shang of non-balance nature, makes system of nature produced is big of difference, on Nano material of research will makes people from micro to macro of transition has more in-depth of awareness. Characteristics of nanomaterials?

When the particle size down to the nanoscale, will lead to sound, light, electricity, magnetism, and thermal performance of new features. For example: is a wide research of II-VI semiconductor cadmium sulfide, the absorption band edge and luminescence spectra of peak position will significantly blue shift as the grain size decreases. According to this principle, can control the grain size to get different energy gap in cadmium sulfide, which greatly enriched material for content and is expected to get new use. We know the type of material is limited, micro-and nano-CDs are made of cadmium and sulfur, but by controlling production, band gap and luminescent properties of different materials can be obtained. In other words, through nano-technology is a new material. Nano Element Particles Often has a large surface area per gram surface area of the solid can reach hundreds of thousands of square meters, which makes them available as a highly active adsorbents and catalysts, hydrogen storage, organic synthesis and has important applications in areas such as environmental protection.

Nano-effects means that nano-materials with traditional materials do not have the exotic or unusual physical, chemical characteristics, such as conductive copper to a Nano-grade boundaries are not conductive, insulating silicon dioxide, crystals, and began conducting at a Nano line.

Development of nanometer drug carrier

Common nano drug carriers include inorganic and polymeric nano-drug delivery nano drug carriers. Among them, the polymeric nanoparticles as drug delivery research earlier, has a small amount of polymer-based drug of nano carrier got some European and American countries the drug agency approved for clinical treatment. This is because the polymer nanoparticles good biocompatibility, toxicity, drug coated through physical or chemical bonding in its polymer nanoparticles, excreted polymeric carrier via degradation after their release. Common inorganic nano-drug delivery system include magnetic nanoparticles, mesoporous silica, Nano-carbon materials, quantum dots, and the inorganic nano-drug delivery system, in achieving the targeted drug delivery, controlled-release and sustained-release drugs, as well as targeted cancer therapy is a good prospect

Nano-elements multi-purpose

 

Nanometer (nm), also known as NM, as well as cm, DM and m, is a unit of measurement of length. Specifically, a nanometer is equal to the length of one-zero meters, equal to 4 times the Atomic size, one out of 10,000 hair thickness; figuratively speaking, a Nano-objects dropped on the table tennis is like a ping-pong ball placed on the Earth. This is the concept of nanometer length.

Spherical Nano Element surface area is proportional to the square of the diameter of the Particles, the volume is proportional to the cube of diameter, it is inversely proportional to its surface area and diameter. As the particle diameter gets smaller, specific surface area will increase significantly, indicating the percentage of atoms on the surface will be significantly increased. For diameters greater than 0.1 micron particle effects are negligible when at less than 0.1 micron sizes, a drastic increase as a percentage of surface atoms, even 1 g the sum of ultrafine particle surface area of up to 100 square meters, the surface effects can not be ignored. Super micro particles of surface and chunks objects of surface is is different of, if with high rate electronic microscope on gold super micro particles for TV camera, real-time observation found these particles no fixed of form, with time of changes will automatically formed various shape (as cubic eight surface body, ten surface body, 20 surface body more Ulrich,), it both different Yu General solid, and different Yu liquid, is a associate solid. Under electron beam irradiation in electron microscopy, surface atoms as if into the “boiling” status, size greater than 10 nm, I just don’t see this instability of the structure and micro-particles with a stable structure.

Nano-materials, we can use a “lighter, higher, stronger” it summed up in six words. “Lighter” refers to the aid of nano-materials and technologies, we can prepare a smaller performance even better devices, reducing the volume of devices to make it lighter. Need three houses to the first computer store, and with micron semiconductor manufacturing technology, miniaturization is realized, and popularity of the computer. In terms of energy and resource use, this “small” benefits were all very stunning. “Higher” refers to the nanostructured materials is expected to have a higher optical, electrical, magnetic and thermal properties. “Stronger” refers to the mechanical properties of nano-materials have a stronger (such as strength and toughness), Nano ceramics, Nano is expected to solve the brittleness problem of ceramic, and may exhibit similar to the materials such as metal-plastic
