Technological singularity is an event in the future time that will dramatically transform the human race. The technological singularity is also referred to as Singularity. It will provide the means of doing things that can only be imagined today. These objectives are considered achievable by many present visionaries. The era of Singularity will be ushered on the bases of three disciplines also referred to as GNR, Genetics, Nano Technology and Robotics or Artificial intelligence (AI). Genetics is a branch of Biomedicines that study DNA of organisms. DNA is an almost an indestructible molecule which is found in living ...

1. Introduction to the Technique Magnification and high resolution imaging are very important in materials science, especially at present when nanotechnology materials are being created. Magnification and high resolution imaging can help in the characterization, identification, and confirmation of the existence of the desired material. Magnification and high resolution imaging become problems when the size of the assessed material becomes too small; such as, they are beyond the micrometer scale. Ordinary techniques in microscopy such as light microscopy where in a traditional light microscope is used could not suffice. Fortunately, in 1931, two scientists named Ernst Ruska and Mx ...

The ubiquitous climate change and the attendant consequences in the forms of flash floods, earthquakes, tsunamis etc has further intensified efforts at seeking alternative sources of energy to the currently used fossil fuels that contribute so much to the deterioration of the environment and the menace of climate change. The alternative forms of energy, termed green energy are renewable sources of energy e.g. solar energy. Theses green sources of energy do not contribute to the deterioration of the environment. The industrial production of hydrogen gas H2 is dependent on heavy use of fossil fuel-generated electricity to power the process ...

1. Introduction Nano is derived from the Greek word, Nanos, meaning extremely small. Nanotechnology, as the name indicates, is the science and technology of preparation, characterization and application of matter in the size range of a billionth of a meter (1 x 10-9). Nanotechnology can be used to manipulate atoms and molecules, creating new materials and machines with greatly improved qualities as compared to those of their precursor materials. This is achieved by constructing layers of atoms or molecules through various fabrication methods such as solution processing, melt processing, in-situ deposition etc. In addition to functioning as nano-scale devices, nanoparticles ...
