Nanophotonics is the study of the effects of light at the nano-scale. This course on nanophotonics coupled with my previous courses on nanoscale circuit fabrication has taught me a great deal about the nano-scale and nano-electronics. Described in this paper are the uses of several nanophotonic principles which allow us to make and measure in scales never before possible. The first topic, plasmonics, is a physical phenomenon that allows us to measure small changes in thicknesses and also to see well
This study demonstrates a facile, one−pot preparation of casein hydrolytic peptides (CHPs)–conjugated crystalline AuNPs having average core size about 20 ±10 nm and morphology found to be hexagonal shaped. The CHPs are competent to form the monolayer on the AuNPs surface resulting electrostatic interparticles interaction, and plays an important role in stability for long periods of time (12 months). The X−ray photoelectron (XPS) spectrum, showed a strong peak for the pure ‘Au’ phase. The FTIR spectrum
Surface plasmon resonance sensor is a promising optical sensor. In 1902, Wood discovered that there are loss of small area in the spectrum after the light beam passed through a grating[4]. This discovery has been intensified by many researchers. Until 1971, Kretschmann used a prism as a substrate and covered its bottom with thick metal film to achieve SPR detection [5]. Thereafter, SPR technology achieved great development. According to Liu and his colleagues in 2013, this prism based SPR sensor
effect markedly, even up to 1014 times the common Raman signal [3], which overcame the low sensitivity of the common Raman technique. The enhancement is mainly owing to the amplification of the light resulting from the excitation of localized surface plasmon resonances
Abstract Every 67 seconds someone in the United States develops Alzheimer's disease (AD). AD is a neurodegenerative condition characterized by cognitive decline accompanied by memory loss. It is the only top ten cause of death in the United States which cannot be prevented, cured, or slowed. One of the proposed causes of AD is the formation of structures containing amyloid fibrils. Amyloid fibrils are insoluble fibrous protein aggregates sharing specific structural traits. Aside from AD, amyloid
TFIIF to complete the pre-initiation complex in transcription, different methods such as co-immunoprecipitation (co-IP), glutathione-S-transferase (GST) pull down assays, yeast-two-hybrid (Y2H) assays, isothermal titration calorimetry (ITC), surface plasmon resonance (SPR), nuclear magnetic resonance (NMR) spectroscopy and etc. can be use to validate PPIs. Yet, doing one experiment using one method is not enough to validate the PPI between two or more proteins. Factors such as overexpression of proteins
Photonic Band Gap Materials:  A little history behind Photonic Band Gap materials (PBG)? In 1987, an American physicist and engineer named Eli Yablonovitch and Canadian physics professor from the University of Toronto Canada, Sajeev John constructed artificial structures that then became the concept of PBG material. In order to evaluate this concept they created a 3D prototype diamond lattice in Plexiglas, which is a type of acrylic glass material. With this creation they were able
Introduction: We are here analyzing the deal of Heinz which happened with 3G capital and Berkshire Hathaway. If we look into the motives of the deal .The main objectives are : • To diversify into ever growing food business by Berkshire Hathaway. • To somewhat focus on the food business in case of 3G capital by firstly acquiring Burger King then Heinz. • Heinz which is synonymous to ketchup across the world makes the deal lucrative for both the parties as all the channels and capabilities of Heinz
Nasopharyngeal carcinoma is one of the head and neck cancer and it’s incidence is less than 1 per 100000 population (about 2-3%). Surgery, chemotherapy and radiotherapy are common treatment modalities for nasopharynx cancer. Nasopharynx is surrounded by critical organs such as brain stem, spinal cord, temporal lobes, eyes, middle and inner ears and parotid glands; so it is impossible to deliver high doses to the tumor. Therefore, nasopharyngeal carcinoma presented a challenge to radiotherapy and

According to E.A. Zerhouni, MD, former director of the National Institutes of Health has described molecular imaging as having “the potential to define itself as a core interdisciplinary science for extracting spatially and temporally resolved biological information at all physical scales from Angstroms to microns to centimeters in intact biological systems.” (Eugene P. Pendergrass New Horizons Lecture, Radiological Society of North America meeting, 2007)1. Molecular imaging aims at developing imaging

There are many other famous brand names in the company¡¦s portfolio besides Heinz itself, StarKist, Ore-Ida, Plasmon, and Watties. In fact, Heinz owns more than 200 brands around the world and makes over 5,700 varieties. The Company was founded in 1869 by Henry J Heinz called Heinz and Noble Company. In the 1870s during the depression the company went into voluntary
I can, I will & I must. These words have been key point behind my learning. It has helped me to frame my targets & reach the goals of my carrier, which I strongly believe in materials science. The modern world is loaded with ballistic variations in gadgets & devices, with miniaturization being the ace of the cards. With the technology getting bigger the demand for Nano devices has been larger and Materials Sciences & engineering has a lion’s share in accomplishing it. This extrudes me to think beyond

Nanoparticles Nanoparticles are defined as the microscopic particles with at least one dimension less than 100 nm. Nanoparticles are of immense scientific interest because of their vast potential applications in biomedicines, computer, electronics, and defense industries. Nanoparticles are of great scientific and technological interests because they can effectively act as bridge between the bulk form and atomic or molecular structures of the materials. Bulk materials possess constant physical and
H.J. Heinz Company H.J. Heinz Company, commonly known as Heinz, famous for its “57 Varieties” slogan, was founded in 1869, by Henry John Heinz, in Sharpsburg, Pennsylvania. In 1869, the 25 year old Henry went into business with L. Clarence Noble as “Heinz & Noble.” The first product they launched was none other than horseradish. The sauce was unique in that it was sold in clear glass bottles to display its purity, whereas competitors used colored glass to hide the poor quality of their products

2.5.1 Raman Spectroscopy Inelastic scattering of light by elementary excitations such as phonons and plasmon in the material is termed as Raman scattering. When a beam of light (UV-Visible and IR region) of frequencyI is incident on a solid, most of the light gets scattered elastically, i.e., without change in energy. A small fraction of light is scattered inelastically with frequencies I ± m, where m are the characteristic vibrational frequencies of the e- cloud in the molecule/solid. Figure
