This work reports the attempts to carry out pulsed laser ablation in liquid (PLAL) for synthesizing colloidal copper oxide nanoparticles (NPs). Copper oxide NPs was synthesized by 7ns Nd:YAG laser ablation of high purity copper target immersed in different solutions; ethanol, acetone, and water. The optical and morphological properties of copper oxide NPs were investigated. It was found that the optical absorbance, energy gap, size, and distribution of copper oxide nanoparticles are dependent on liquid type. Plasmon peak was observed at 550nm for Cu NPs ablated in acetone and methanol liquids, while it was disappeared for those ablated in water. Atomic Force Microscopy (AFM) analysis showed that the average grain size of copper oxide particles ablated in acetone, ethanol, and water were 276 nm, 300, and 360nm, respectively. Fourier Transform Infrared (FTIR) was used to study the vibrational frequencies between the bonds of atoms for a synthesized copper oxide NPs at different liquids. All these results confirm the complete oxidation of ablated copper.

Engineering and Technology Journal, 2013, Volume 31, Issue 1, Pages 107-114

There are three basic encryption methods: hashing, symmetric cryptography, and asymmetric cryptography. Each of these encryption methods have their own uses, advantages, and disadvantages. All three of these encryption methods use cryptography, or the science of scrambling data . Although there can be several pieces to an encryption process, the two main pieces are the algorithms and the keys. As stated earlier, algorithms used in computer systems are complex mathematical formulas that dictate the rules of how the plaintext will be turned into ciphertext. A key is a string of random bits that will be used by the algorithm.
This paper proposed a method which generates the key that draw from parts of the image. The size of the key is used with the suggested algorithm to encryption of the text. This method could be applied to Symmetric cryptography or Asymmetric cryptography.
