The Existence of Two States in Liquid Water and Its Impact on Biological and Nanoscopic Systems Around Us
Abstract: This work reviews several properties of liquid water, including the dielectric constant and the proton-spin lattice relaxation, and draws attention to a bilinear behavior defining a crossover in the temperature range 50 ± 10°C between two possible states in liquid water. The existence of these two states in liquid water plays an important role in nano-metric and biological systems. For example, the optical properties of metallic (gold and silver) nanoparticles …

Structural and Optical Study of CdSe Q-dots
Abstract: In this paper we have report the properties of CdSe Q-dots. Calculations of different parameters for different sizes of CdSe Q-dots are presented. The XRD analysis used to find the composition, crystal structure and crystallite size. Scherrer equation is used to calculate the Nano crystallite size. XRD analysis reveals that the CdSe QD crystallite sizes in the sample are 3.26 nm, 3.72 nm, and 3.20 nm by applying the appropriate …
