A new microscopy technique is introduced, image scanning microscopy (ISM), which combines conventional confocal-laser scanning microscopy with fast wide-field CCD detection. The technique allows for doubling the lateral optical resolution in fluorescence imaging. The physical principle behind ISM is similar to structured illumination microscopy, by combining the resolving power of confocal-lase...

Indian coal-based thermal power stations produces huge amount of coal combustion residues. Proper disposal, management and utilization these ashes have always been a challenge before the plant people. In order to find out potential use residues one need explore look deeply into its various characteristic properties. present study residue samples from station eastern India were used for characte...
