A basic eigenvalue bound due to Alon and Boppana holds only for regular graphs. In this paper we give a generalized Alon-Boppana bound for eigenvalues of graphs that are not required to be regular. We show that a graph GG with diameter kk and vertex ... see more

The object of research is studying Raman scattering technique, photoluminescence and some optical properties of silver nanoparticles created by eco-friendly technique which independent on a long time, effort, energy and high temperatures, and with the hig... see more

Ramania fruit (Bouea macrophylla Griffith) is a tropical plants, as a new natural source of polyphenols. The content of these polyphenols is very abundant, especially in the seeds. The polyphenol content is widely used in the pharmaceutical world, as anti... see more

In this work, the Raman spectrophotometer (HG.2S Jobin Yvon) was interfaced with labVIEW card to act as data acquisition system instead of the chart recorder. The interface of the Raman (HG.2S Jobin Yvon) with the labVIEW card require some modifications ... see more

Laser based time-gated Raman Spectroscopy experiments for detection and identification of nitro-aromatic sample which premixed with soil and sand in different concentrations are conducted. A back-scattered stand-off Raman spectroscopy set-up using a frequ... see more

The detection of hazardous chemicals, explosives, improvised explosive materials, energetic materials and their associated compounds for security screening, forensic applications and detection of unexploded ordnance is an active area of research. The resu... see more

Raman Effect is the measurement of the intensity and wavelength of the inelastically scattered radiation that falls on a molecule. The electric field of the incident radiation polarizes the molecule on which it falls and this leads to the creation of an o... see more
