Nano-composite plastics and carbon nanotubes have been utilized for industrial and consumer packaging, the later offering an improved packaging solution for electronics components by making the materials used lighter and stronger. Nano-porous silica is a high porous, low-density solid material that supports various temperatures making it a great insulation product that can be applied in a wide range of fields from pipe insulation to refrigerators and even microelectronics. Nanoparticle based colloids are employed in the manufacturing of sunscreens, paints, and printer inks and nano-coatings can be applied in order to obtain scratch resistant surfaces. Composite nano-materials can be considered the basis for all the other current and future commercial applications of nanotechnology.

My element is Silver. The atomic number of silver (Ag) is 47. Silver is in group 11 and period 5. The mass number of Silver is 107, and its electron configuration is [Kr] 4d^10 5s^1. Silver was one of the first five metals discovered and used by humans. Silver’s melting point is 1,763.2 degrees fahrenheit. Silver is commonly used to make mirrors, as it's the best known reflector of light. Silver is also commonly in silverware, where the appearance is important. Silver is most commonly used in jewelry, where sterling silver is 92.5% silver.

Silver (Ag) is a metallic element with the atomic number of 47. A soft, white, lustrous transition metal possesses the highest electrical conductivity, thermal conductivity and reflectivity of any metal. Silver occurs in its pure, free form as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. More abundant than gold, silver metal has functioned in many pre modern monetary systems as coinable specie, sometimes even alongside gold.

The polyvinyl alcohol (Mw ¼ 125,000 gm/mole, polydispersity index: PDI ¼ 0.25), and silver nitrate (AgNO3, 99.8% purity) were purchased from the SigmaeAldrich Chemicals. The PVA-Ag nanocomposite films were prepared by the in-situ chemical reduction method [8e12]. Sample b with 0.4 wt % of silver was prepared by dissolving silver nitrate in 5 mL of bidistilled water and 1.5 g of PVA in 50 mL of the bidistilled water. The temperature of PVA solution was kept at 65 C for 2 h. When the PVA becomes completely dissolved, the AgNO3 solutionwas added drop by drop by using a burette at constant 65 C for 0.1 h.

The photoelectron combines with a silver ion to form a neutral metallic silver atom. (Earle

Silver nitrate AgNO3 (≥99.0%) and PVP (Average molecular weight ~55,000) were purchased from Sigma-Aldrich. Ethylene glycol (EG) and Hydrochloric acid (HCl) were purchased from Merck specialities Pvt Ltd. All the chemicals were used as received without any purification. We synthesized silver nanocubes (Ag NCs) by a typical polyol method. In a typical synthesis, 12.5 mL of ethylene glycol was poured in 50 mL of round bottom flask and heated at 140°C for 1 h under stirring. An amount of 2.5 mL of HCl solution (3.3mM in EG) was quickly injected into the reaction mixture. After 10 min, 7.5 mL of AgNO3 solution (94mM in EG) and 7.5 mL of PVP (147mM in EG) solutions were simultaneously injected into the stirring solution. The reaction mixture was

Silver has been used since Roman times as a disinfectant because of its well-known antimicrobial properties. AgNPs are considered attractive building blocks for nanomaterial architectures based upon the nanoparticles size and shape (Shipway etal 2000).

The conclusion of the paper restated the benefits of the usage of gold nanoparticles, citing its flexibility of usage, and reviewed the discoveries of the experiments. It was discovered that benign cells need more than twice as much light intensity to be killed than malignant cells. Finally, it discusses how the procedure would need to be altered to be used in vivo. Since a wavelength between 650 and 900 nm would be required to penetrate even a few centimeters of tissue, the next step in research is altering the pure gold nanoparticles in order to maximize absorption. The

It has an attractive shiny appearance, although it discolours easily. Silver (Ag), chemical element, a white shiny metal valued for its attractive beauty and electrical conductivity. Silver is period 5 of the periodic table, between copper and gold, and its physical and chemical properties are halfway between those two metals. It is used for jewellery, mirrors, coins and silver tableware, where appearance is important. Mirrors are almost always if not always made with silver, as researchers have proved that it is the best reflector of visible light. As a result of the continually growing demand for the precious white metal is a big indicator for the future price to increase dramatically. One of many developing fields is silver nanoparticles of technology, that is producing demand for silver that is still not yet fully priced into our current market. Silver is the most important valuable metal after gold and in fact silver has no equal. Which brings us to our next topic, when it comes to conducting electricity and/or heat, silver is the only way to go. As we previously stated before, it is the best and most efficient reflector of light. Silver is widely considered as the primary choice for growing range of technologies, due to its characteristics such as its antimicrobial properties (antimicrobial is an agent that kills microorganisms or stops their growth) (En.wikipedia.org, 2018). The first mass-market use of silver was photography aside from money and jewellery. Technology utilities the conductivity of silver and has made a huge demand in the manufacture of solar energy panels. One of the newest science fields are also creating potentially significant demand for silver along with the technology utilities. A nanoparticle is a submicroscopic size unit, measuring between 1-100 nanometres. Silver nanoparticles have numerous uses in medicine and technology. Silver is one of the most

The major differences of these two chemical bonds are shown obviously in the lab. Metals has larger density values, higher hardness than polymers and able to conduct electricity while polymers is not able to. To understand the distinction in atomic bonding, one can utilize the knowledge in his

The way that metal ions react when exposed to heat is the principle behind color production. Each metal ion produces a specific color (see table). The color is produced when the electrons in the metal ions are "excited", causing them to jump to a different energy shell. It is when the electrons return to "ground state" that they emit their own light.

At small sizes, the flexibility of a particle to scatter lightweight of various wavelengths is predicated on particle size. An example of this is zinc oxide, which appears white in sunscreen once the particles are macroscale, however transparent when the particles are nanoscale. In a similar fashion, thin films composed of our silver nanowires are extremely clear albeit they are composed a material that is opaque at a macroscale.

Polymer composites are the blend of polymers and filler materials. Disadvantages of polymers such as low mechanical and electronic properties can be improved through reinforcing with much stronger and highly conducting filler materials. Thus, fabricating polymer composites is of mutual benefit to both polymers and fillers. Furthermore, advanced-desired applications can be tailor-made. Also, compared to polymer micro/nanocomposites, polymer nanocomposites show much more improved properties such as extremely smooth finishing, excellent mechanical and electrical properties at lower loadings as low as 0.025 volume % (Schandler, Brinson & Sawyer 2007). In the current chapter, both polymer microcomposites and polymer nanocomposites are briefly discussed.

The interest in plasmon modes dates back to the beginning of the 20th century, but recent advances in structuring, manipulating and observing on the nanometer scale have revitalized this field even though these technological advances were at first driven by the increasing demand for a semiconductor based integrated electronic components, optical applications are now receiving increasing attention. Guiding light in an integrated optical system and interfacing with electronic components remain important challenges for research and development today. Nanostructures metals are believed to be one of the key ingredients of such future optoelectronic devices.
