Synthesis of silver nanoparticles in fresh tea leaves extract has been carried out in this work as an environment friendly approach and to explore its antimicrobial potential. The formation of silver nanoparticles is characterized by UV-Vis spectra. The average size of the nanoparticles, the value of the d-spacing has been revealed by the data obtained from(More)
Artificial Neural Network (ANN)s can be modeled for High Energy Particle analysis with special emphasis on shower core location. The work describes the use of an ANN based system which has been configured to predict locations of cores of showers in the range 10 to 10 eV. The system receives density values as inputs and generates coordinates of shower events(More)
Cosmic showers, during the transit through space, produce sub products as a result of interactions with the intergalactic or interstellar medium which after entering earth generate secondary particles called Extensive Air Shower (EAS). Detection and analysis of High Energy Particle Showers involve a plethora of theoretical and experimental works with a host(More)
High energy neutrinos passing through the Antarctic ice and lunar regolith can produce radio pulses. A good number of experimental groups have been continuing investigations on these radio pulses. Along with VHF -UHF radio pulses, VLFLF-MF radio pulses are also emitted from the Antarctic ice-air interface and lunar regolith–vacuum interface due to excess(More)
Cosmic showers, from their places of origin in space, after entering earth generate secondary particles called Extensive Air Shower (EAS). Detection and analysis of EAS and similar High Energy Particle Showers involve a plethora of experimental setups with certain constraints for which soft-computational tools like Artificial Neural Network (ANN)s can be(More)
In this work, we report the synthesis, characterization and biological application of highly stable CdTe/ZnS (cadmium tellurite/zinc sulphide) Core/Shell (CS) quantum dots (QDs) capped with mercaptosuccinic acid (MSA). The CS QDs were synthesized using a simple one-pot aqueous method. The synthesized CdTe/ZnS CS QDs were found to exhibit excellent stability(More)
