Abstract The Greek-Roman Isis temple is located on the west bank of Luxor; Upper Egypt was made of sandstone and decorated with different kinds of wall paintings. It suffers from many causes of deterioration and degradation mainly ground water‚ salt weathering‚ and different types of dirt accumulations on the relives and paint surface such as soot‚ grease‚ wax‚ biodeteriorated colored patches‚ bat patches‚ waste of birds and even house fly specks. All these lead to the gradual disappearance of paintings

STATEMENT OF PURPOSE “The Art & Science of building stuff that does stuff at the Nanometer scale” * Richard E Smalley I am always intrigued by the depth involved and the broad range of sciences‚ this statement covers‚ for the purpose of defining Nanotechnology. It is one of the key statements which made this field curious to me. My interest in this field began‚ when I first came across the essay “There is Plenty of Room at the Bottom” written by Richard P Feynman. And thereafter‚ from curiosity

LETTER OF RECOMMENDATION It gives me immense pleasure to recommend Mr. Sarang Gumfekar for graduate studies. As a lecturer in Engineering Science Department‚ I have had the pleasure of knowing Sarang for last four years. I taught him theory courses such as Applied Science-I and II and also had been his lab instructor for Applied Physics-I and II. I was especially touched by his conscientious way of study and approach towards carrying the experiments. Once in the final year‚ I read his

The challenges are such as: i. The homogeneous dispersion of the nanomaterial in a small scale. ii. Development of low cost materials. Over the years‚ nanocellulose has been widely used in the application of nanocomposites (Islam et al.‚ 2013). It serves as a cost effective and sustainable reinforcement in the composite

Introduction In the last two decades‚ new terms with the prefix `nano’ have rushed into the scientific vocabulary; nanoparticle‚ nanostructure‚ nanotechnology‚ nanomaterial‚ nanocluster‚ nanochemistry‚ nanocolloids‚ nanoreactor and so on. Nanoparticles‚ are defined as particulate dispersions with a size in the range of 10-100nm (Gubin et al‚ 2005). Magnetic nanoparticles have gained a remarkable interest in the last
