...family history of melanoma, and weakened immune system. Furthermore, the signs and symptoms for malignant melanoma. Skin sore that fails to heal, spot or sore that becomes painful, itchy, tender, or bleeds, spot or lump that looks shiny, waxy, smooth, or pale, a firm red lump that bleeds or appears ulcerated or crusty and a flat, red spot that is rough, dry, or scaly. Malignant melanoma can be diagnosis by doing skin examination and physical assessment, any abnormal changes in a Mole, biopsy of the skin, Clinical test TNM is used to see further staging of the cancer, Clinical experts also use the ‘ABCD” rules for diagnosing the patient with skin cancer, complete blood count and chemistry Panel, urinalysis-urine, and chest X-ray, MRI. Malignant melanoma can be prevented by covering up, applying sunscreen before going out, wearing sunglasses, and clothes that can cover the skin. Furthermore, spending less time in sun can prevent melanoma, and checking the skin so that you can see any changes. Malignant melanoma can be treated by doing surgery, chemotherapy, radiation therapy, and boosting immune system to help the body fight cancer. The percentage of people who have malignant melanoma in 2014 in different places are: 23%of men and 14% of women had it on head and neck, 19% of men and 25% women had it on the arm, 41% of men and 20% of women had on the trunk, 13% men and 38% of women had on legs.

...Chameleons have a second layer of cells called iridiophore just beneath the first. The crystals in that layer are larger and reflect light waves that are in the infrared wavelengths. This is likely a protective measure that chameleons are using to regulate their temperature, as they are cold blooded. There is another crystal containing layer of cells. these disorganized crystals are spaced out more and much larger then those in other layers. Since they are larger they reflect longer wavelengths of light. This layer can manipulate infrared light. they also reflect a greater range of these wavelengths. This layer works as thermal protection, nature sunscreen this works great, since they live so high in the forest because these animals can't change their body temperature. So, changing their lower layer is one way they can affect how much infrared light and heat is absorbed into their...

...Nanotechnology: Is it safe or are we on a path to disaster? In the last few decades, science has driven technology to new heights. The most prominent and significant change has been the reduction in size of these technologies. However, in the effort to simplify our lives by making things smaller and smaller, some of us fail to see the risk in such bold endeavors. This quest to manufacture objects at the microscopic scale has created the field of Nanotechnology which refers to the creation of devices and materials on extremely small scales. The products of Nanotechnology are composed of individual particles called Nanoparticles which have one dimension (width, height, or length) that is less than 100 nanometers. To put that in perspective, the width of a human hair is about 10 to 1000 times bigger than a nanometer. At such miniscule size, materials can be created with valuable chemical and physical properties, such as the ability to conduct electricity in the case of electronics, which enable for a wide range of technological applications, ranging from faster computer chips to new ways of treating cancer. The incorporation of Nano-technologies in commercial products has begun what some scientists and journalists are calling a “Nano revolution.” In other words, more and more technologies have at least some component that was engineered using Nanotechnology. With such wide range of applications, it is no wonder groups like the International Council of Nanotechnology (ICON) have...

...Nanotechnology (first used the term nanotechnology by Richard Feynman, in 1959) can be defined as the manipulation of atoms and molecules at nano (one billionth) scale (1–100 nm) to produce devices, structures or systems having at least one novel or superior property. The materials having at least one dimension in the nano scale are called nanomaterials. 10-9 meter (1 nanometer) to 10-7 meter (100 nanometer) Human eye can visualize up to 20μm only 1μm = 10-6 m DNA= 2.5nm- 3nm Protein= ̴ 5 nm Virus= ̴ 150 nm Human hair= ̴ 5000 nm Properties of Nanomaterials 1. The surface area to volume ratio of the nanomaterials is relatively larger than that of bulk materials of the same mass. This increases the chemical reactivity and affects strength and electrical properties of the material. 2. The quantum confinement is observed at nanometer sizes that changes the optical, electronic and magnetic properties of the material. The band gap increases as the size of the material is reduced to nanometer range. I II III IV Reduction in particle size increase in its Surface area Now, material is NANO so surface area will big… HOW? Let us consider a sphere of radius ‘r’ Surface Area = 4 x π x r2 Volume = (4/3) x π x r3 ratio of SA to Vol = 3/r Thus, radius of sphere decreases, Surface area will increase Let us consider a cube of sides 1 m Area= 6 x side2 = 6 x 1m2 = 6m2 Now, cut the same cube into 8 pieces, then the SA will increases Area= 6 x (1/2)2 x 8 = 12m2 Similarly, the...

...Nanotechnology Nanotechnology, which is widespread subject, is what is likely to be the driving force of many scientific changes of our earths future. It’s the technology of manipulating matter at the nano scale. Nanotechnology is applied in countless different fields such as science, health care, agriculture, security, computing etc. The ground breaking developments that are made in these various fields due to nanotech is why the world will continue to invest its time and money into the subject matter. “Many experts even predict that Nanotechnology is going to have as significant a place in the field of science and technology as the steam engine had at the time of its invention. Due to the potential it bears most developed and developing countries are making significant investment into nanotechnology research and development where the combined investment from the private and public sector is estimated to be around $12 billion annually.” (Michelson et al, 2008) The revolution of nanotechnology is not only expected to make many products and services friendlier economically, but is also going to allow for the miniaturization of control systems. Diseases will be more simple to cure, and we will have new cures for diseases that we do not yet have cures for. On the contrary with advantages come disadvantages. There are many widespread discussions regarding the negative effects of nanotechnology. Nanotechnology has its benefits but can also be lethal if used improperly...

...Nano technology in the automotive industry:- ABSTRACT What is Nanotechnology? Nanotechnology is the engineering of materials on the scale of 1 nanometer (nm) to 100 nm, a nanometer being 1 billionth of a meter. At this level, the basic physical laws governing macro objects undergo a drastic change. A macro particle is a cluster of atoms arranged together in random order. The formation of the structure is left to nature, and control over the properties of the material is difficult. Nanotechnology, on the other hand, is a bottom-up approach where materials are created by placing individual atoms together. This decreases the randomness in the structural formation, enabling significant control over the properties of the material. Mechanical properties such as strength, ductility, and resilience can all be incorporated into one material. Currently, nanotechnology is functioning as an enabling technology. It is being used to enhance the properties of existing materials. This is largely attributed to the fact that the technology has clearly not been understood and there is still much more to nanotechnology than meets the microscopic eye. It is rare for a single technology to have the power to dramatically influence almost every major industry in the world. Nanotechnology falls into this category and offers fundamentally new capabilities to architect a broad array of novel materials, composites and structures on a molecular scale. This technology has the potential to drastically...
