Conductivity in metal-organic frameworks Metal–organic frameworks (MOFs)‚ are a class of crystalline materials whose crystal structure is made up from metal-containing clusters connected by multidentate organic linkers1‚2. MOFs are attracting considerable attention due to the possible rational design of crystal structures of coordination frameworks with versatile metal ions and organic ligands. In principle‚ MOFs topologies along with intermolecular distances between various building blocks can be

Fibre Optics Technology over the past century has advanced greatly. Fibre optics however is being utilized since more than a hundred years. Optical fibre is a model that has evolved greatly over time. From guided transmission lights experiments to lasers and light emitting diodes (LED)‚ and to dense wavelength-division multiplexing (DWDM)‚ the area under which optical fibre can be used has expanded. One of the modern and commonly used applications

3. RESULTS AND DISCUSSION 3.1. Powder X-Ray diffraction analysis The grown Cd doped LSMH crystal were subjected to powder X-ray diffraction studies using a Rich Seifert X-ray diffractometer employing CuKα (1.54058 Å) radiation‚ scanning angle ranging from 10° to 70° at a scan rate 1°/min to confirm the crystalline phase of the grown crystal. Fig 2 shows the X-ray powder diffraction patterns of pure as well as Cd doped LSMH single crystals. The obtained (h k l) values are indexed using the JCPDS

Thinking about the future is the thing that takes a lot of our time and efforts being computer oriented. We have to imagine‚ try to figure out what the future will bring us. We are supposed to lead our generation in looking for new and life enhancing technologies to make man ’s life easier and more enjoyable. How will it look like? [pic]THIS IS THE MOST IMPORTANT QUESTION THAT CAME TO OUR MINDS. • Will we be able to talk to our computers in the future? • Will they respond freely

Abstract : The purpose of the experiment was to determine the wavelength and light intensity effect on the reaction rate of photosynthesis. Photosynthesis is the conversion of light energy to chemical energy in the form of organic compounds. There are two phases in photosynthesis‚ the light reaction and dark reaction. The following experiment tested only the light reaction. Photosynthesis takes place on the chloroplast‚ and the chloroplast contains chlorophyll pigments which absorb light energy
