Fig. 1a shows the UV–vis absorption spectrum of the as-prepared Ag@C-nanowires suspended in deionized water, exhibiting a main peak at 386 nm and a shoulder peak at 360 nm, corresponding to the optical finger print of silver nanowires. The absorption peak at 360 nm is attributed to the longitudinal plasmon mode of silver nanowires and is similar to that of the bulk silver, and the absorption peak at 386 nm is attributed to the transverse plasmon mode of silver nanowires. These two absorption peaks

TARGET MARKETING - MEANING, BASIS AND ITS NEED It is not possible for a marketer to have similar strategies for product promotion amongst all individuals. Kids do not get attracted towards products meant for adults and vice a versa. Every segment has a different need, interest and perception. No two segments can have the same ideologies or require a similar product.Target Marketing refers to a concept in marketing which helps the marketers to divide the market into small units comprising of likeminded

CASE STUDY: SENSODYNE OVERTAKES COLGATE IN SENSITIVE CATEGORY INTRODUCTION The sensitive toothpaste segment accounts for less than 10% of the country 's Rs 5,400-crore toothpaste market at Rs 470 crore, but is growing at 50% a year. Oral care giant Colgate Palmolive, which controls about 53% of the country 's toothpaste market, has been selling its Sensitive brand in India since the last seven years. India had very low levels of awareness on the condition of tooth sensitivity. Over the past

Nitrate (NO3-) supplementation has been widely researched for its effects on exercise performance since Larsen et al 2007 found that it decreased the oxygen cost of submaximal aerobic exercise. The effect of NO3- in the body is tied to the production of nitric oxide (NO), which is an endogenous gas that plays a regulatory role in many processes in the human body, including; blood pressure, calcium handling, mitochondrial biogenesis, excitation-coupling contraction, oxidative stress, regulation of

Wigal, Lebanon Valley College PURPOSE OF THE EXPERIMENT Oxidize benzoin to benzil using ammonium nitrate and copper(II) ion as a catalyst, monitoring the reaction by thin-layer chromatography. Characterize the product using melting point measurement and infrared spectroscopy. EXPERIMENTAL OPTIONS Semi-Microscale Oxidation . . . . . . . . . . . . .

Ag+ (aq) + Cl- AgCl (s) Sliver Nitrate- Adding dilute nitric acid. (Sliver nitrate + dilute nitric acid.) Nitric acid reacts. Removes the ions that might also give a unclear precipitate with silver nitrate. White precipitate is formed. Bromide Equation: Ag+ (aq) + Br- AgBr (s) Silver nitrate- Adding dilute nitric acid. (Silver nitrate + dilute nitric acid.) The nitric acid reacts. Removes ions that may give an unclear precipitate with sliver nitrate. Pale cream precipitate is formed

Discussion: There are numerous ways of isolating and purifying a substance, and an investigation of the differences of each procedure were performed. In two different procedures, lead nitrate and potassium iodide were used to isolate and purify pure solid lead iodide, and the differences in the limiting reactant and solid lead iodide was observed. The amount of solid lead iodide was calculated by the measuring the mass of which the solid lead iodide was created in before and after the purification

My first procedure that I completed was the filtration. When I mixed the lead (II) nitrate and the sodium iodide together, I got a bright yellow liquid that turned out to be lead (II) iodide. I believe I did this part of the procedure correct because the color was not too pale and I did not use too much lead (II) nitrate or sodium iodide. I used the correct amount to get the results that were listed on the laboratory, In procedure D, Glassworking, cutting the glass came out great. I followed all

Structural analysis of PbS synthesized by different technique Introduction: Semiconductor Nps and thin films have recently attracted much attention due to their applications in optoelectronics, photocatalysis, microelectronics, energy conversion industries and nonlinear optics [1-3]. These materials have been a new generation of advanced materials due to their novel structural, morphological, optical and electrical properties originating from size quantization [4]. PbS is an important IV-VI

given to drink. Nitrates, phosphates, dissolved oxygen, turbidity, temperature, and pH levels all affect the drinking water quality. Nitrate is very harmful to younger kids and infants if too much is drank. If a baby 6 months or under drinks over the MCL (maximum contaminant level), the young child could get very sick or die from the over drank nitrate. Any person older than 6 months could become ill, but shouldn’t be anything more than a flu-like sickness. Plants use nitrates to. If animals drink
