Spectroscopy

DISCUSSION 6.1 FTIR SPECTROSCOPY It was observed from the FTIR graph that there was no shifting of peaks of metronidazole i,e., characteristic peak of the amine group (N-H streching) present in imidazole nucleus at 1030 cm-1 and presence of NH2 group at 3298 cm-1 in formulation. Hence, there was no interaction between drug and polymer. 6.2 METRONIDAZOLE MICROSPHERES 6.2.1 Optimization of speed (rpm) for preparation of microspheres Metronidazole microspheres were prepared using emulsion…

CHAPTER – 1 1. INTRODUCTION Carbon nanotubes are allotropes of carbon with cylindrical nanostructure. Constructed with length-to - diameter ratio of up to 132,000,000 :1. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of…

XMM Newton:- The XMM-Newton (X-ray Multi-Mirror Mission or High Throughput X-ray Spectroscopy Mission) is an orbiting X-ray observatory launched in December 1999 by ESA (European Space Agency). ). XMM-Newton is the biggest satellite ever built in Europe. It is used for the detection of soft portion of the electromagnetic spectrum (100 eV to 12 keV).Using its large collecting area and highly eccentric orbit, it is making long observations of X-ray sources with extremely high sensitivity. It is…

A common topic in high schools of late has been the use of drugs and steroid use among athletes. High schools have the ability to test athletes for the safety of the students. Although some parents and students believe that drug testing students in high school causes problems that can be avoided by not testing them. In high school athletics, people have proposed to drug test athletes for the safety of the athletes; however, other people believe that they should not be drug tested because it…

History of Communication The communication methods employed by human dates back from a very early stages of civilization. In the primitive ages, communication were based on human voice. But it had a limitation, the distance. As distance grew between two people, messages got hard to convey due to the limitation of vocal cord. Next big step taken by human civilization was the invention of fire. He soon realized that this fire could be used for communication. During the attack in China, soldiers…

Preformulation Study Preparation of calibration curve of Amoxicillin trihydrate [51,53,76] Preparation of stock for Hydrochloric acid Stock solution in 0.1N Hydrochloric acid (0.1N HCl): 10 mg of Amoxicillin was accurately weighed and transferred into 10 ml volumetric flask. It was dissolved and diluted to volume make up to mark with 0.1N HCl to give stock solution containing 1000 µg/ml, after than 1ml take to from 1000 µg/ml and dilute to volume make up to mark of 10ml volumetric flask with…

Chapter 1 Introduction Waste generated from food industries is a source of an untapped energy which is mostly dumped inland fills whereby it releases greenhouse gases into the atmosphere. It is very difficult to treat and recycle food waste due to its composition. Food industry produces large volumes of wastes, both solids and liquid, resulting from the production, preparation and consumption of food. These wastes lead to increasing waste disposal and can pose severe pollution problems and…
