this case, where ID/IG is close to 1, the presence of a 2D peak, further associated to interactions between graphene-like planes, suggests a strong graphitic component.

Field Emission Scanning Electron Microscope (FE-SEM): The activated carbon was scanned by scanning electron microscopy .Figure (3) showed that the prepared activated carbon had an irregular spherical and porous surface, which indicated high surface area.

1. INTRODUCTION Environmental problems related with hazardous wastes and toxic water-pollutants have attracted much attention towards itself. Organic dyes are one of the major groups of pollutants in wastewaters released from textile and other industrial processes. Photocatalysis is a simple and promising technique for solving various current environmental issues. Semiconductor absorbents offer a great potential for eliminating the organic pollutants present. Semiconductor photocatalysts for example

Ways to Prevent and Delay Osteoporosis United States has the highest rate in the world in cases of osteoporosis. According to The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) estimates that 10 million people (8 million women and 2 million men) in the United States have osteoporosis as of 2012” ("Osteoporosis “Lucent Books page 10). After all, 28 million Americans, 80% of them women, are affected by osteoporosis. Ten million already have the disease, and 18 million

distance from the sun Pluto is presumed to be a dark world. Pluto was named after the god of the underworld. It is because of the lengthy distance between Pluto and Earth that we cannot get a clear vantage point of Pluto even with the most advanced microscopes. The United States National Aeronautics and Space Administration sent a probe out in 2006 to Pluto and was expected to be there in nine years (New Views of The Solar System). Thesis Statement. In order to be called a Planet in our solar system

What is Forensic Geology? Forensic Geology is a division of forensic geoscience. Whilst this field of geoscience focuses on the application of environmental science in support of the law or a legal case; forensic geology is principally concerned with the study of rocks, sediments, minerals and soils in support legislation (Pye, 2004). Forensic geology analyses the area under investigation on both a large scale and on a more in depth microscopic scale. Large scale landscape analysis interprets the

Research Statement As a Research Associate (and a former Research Fellow) at the Harvard T. H. Chan School of Public Health (HSPH), my research has focused on i) the development of novel platforms to investigate exposure to particulate matter (Coarse, Fine, and Ultrafine Particles) and gaseous pollutants and ii) to understand the exposure risk, pathways, dose, and health effects. To attain these goals, I implemented state-of-the-art analytical techniques to characterize the exposures, developed novel

Comparative analysis of laser image in medical & Engineering application and its harmful effect on human eye Wavelengths of commercially available lasers. Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the I. Introduction Fig1. Laser effect on eye Laser stand

3.3.5. Nanotexture for Enhanced Cell Adhesion It was expected that the increased surface area on nanotextured PDMS would lead to enhanced cell-surface interactions resulting in stronger cell attachment compared to plain (non-textured) PDMS. To test this, PDMS surfaces were functionalized with an anti-EGFR antibody within the reversibly sealed SEAM platform. SEAM allowed easy integration of nanotextured PDMS and enabled controlled application of fluid shear stress. EGFR is upregulated in several cancer

THE AIMS OF THE RESEARCH Carbogenic nanoparticles or as loosely named in literature C-dots ,CDs, CQDs is a new rising star in the class of photo luminescent materials that were reported to be non- toxic and biocompatible. In terms of shape and internal structure they are largely considered to be quasi-spherical Nano- entities with diameter ranging from 3-30 nm. Their elemental content, C-dots characteristically contains a large amount of carbon (at least 44.50%), along with Hydrogen and Oxygen

PHYSICS PROJECT TO STUDY THE OPTICAL LENS OF A HUMAN EYE Eyes are organs that detect light, and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment; regulates its intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an image; converts this image into a set of electrical signals;
