What does impact factor mean in journals?
Impact factor is commonly used to evaluate the relative importance of a journal within its field and to measure the frequency with which the “average article” in a journal has been cited in a particular time period.
What is meant by nanoscience and nanotechnology?
Nanoscience is a convergence of physics, materials science and biology, which deal with manipulation of materials at atomic and molecular scales; while nanotechnology is the ability to observe measure, manipulate, assemble, control, and manufacture matter at the nanometer scale.
Is nanotechnology a hazardous substance?
Nanoparticles are likely to be dangerous for three main reasons: Nanoparticles may damage the lungs. We know that ‘ultra fine’ particles from diesel machines, power plants and incinerators can cause considerable damage to human lungs.
What is the purpose of nanoscience?
The Aims of Nanoscience Nanotechnology aims to gain control of structures and devices at the atomic, molecular and supramolecular levels, and to learn how to efficiently manufacture and use these devices. Source: The Department of Chemistry, Michigan State University.
What are the advantages and disadvantages of nanoscience?
Nanotechnology offers the potential for new and faster kinds of computers, more efficient power sources and life-saving medical treatments. Potential disadvantages include economic disruption and possible threats to security, privacy, health and the environment.
What are the negative impacts of nanotechnology?
Hazards and risks of nanoparticles include increased production of ROS, DNA damage, genotoxic effects, damages to organs and tissues in humans, effects on growth and yield of crop plants and negative impacts on beneficial bacteria in the environment.
How is nanoscience important in today’s modern society?
Nanotechnology is helping to considerably improve, even revolutionize, many technology and industry sectors: information technology, homeland security, medicine, transportation, energy, food safety, and environmental science, among many others.
