Listing 1 . File SampProg26.java.
/*File SampProg26.java from module 50 Copyright 1997, R.G.BaldwinWithout viewing the solution that follows, write a Java application that illustrates conversion from string tonumeric, similar to the atoi() function in C. The output from the program should be:The value of the int variable num is 3625 ===========================================================*/ class SampProg26{public static void main(String[] args){int num = new Integer("3625").intValue(); System.out.println("The value of the int variable num is " + num); }//end main()}//end class SampProg26

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
