Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

form disaccharides or polysaccharides. It can also join carbohydrates to non-carbohydrate molecules. A glycocidic bond is a condensation reaction which means when it is formed‚ water is a product. This also means that the bond needs water to break (Hydrolysis) which makes it quite strong. This kind of bond is called covalent. Glucose + Sucrose + Water Glucose = H2O Monosaccharides and disaccharides. L.O. 1.2 and 1.3 There are many different essential sugar molecules such as Galactose‚ Fructose

All Biomolecules have certain functions and these molecules all have a unique structure which is why they function in these ways. These molecules are known collectively as macromolecules‚ these molecules are grouped into four main categories which each have there own structure. These structures are the key to the macromolecules functions as each of them do a specific task in the body. Macromolecules are grouped into carbohydrates‚ nucleic acids‚ proteins‚ and lipids. In most cases macromolecules

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

phosphates are easily broken down to release energy and are added in a covalent bond during processes like respiration. ATP is the source for driving active transport and reactions like cellular respiration and photosynthesis. ATP is broken down by hydrolysis. This results in adenosine diphosphate and an inorganic phosphate. Along with this comes the release of energy which can be used all through-out the system. Taking this step one further you can produce AMP‚ which contains only one phosphate group
