Seniors and Depression: The difference between depression and dementia. Depression is a mood disorder; dementias like Alzheimerâs disease, can have similar symptoms but they are different illnesses and have different treatment plans.
From a synthesis standpoint, nanotechnologies can be classified as variations of bottom-up technologies, such as self-assembly, or top-down technologies, such as lithographic methods (Box 1). Many nanotechnologies combine aspects of both strategies.
Nanochemistry or Nanotechnology are related with the production and the reactions of nanoparticles, nanostructures and their compounds.his science use methodologies from the synthetic chemistry and the materials chemistry to obtain nanomaterials with specific sizes, shapes, surface properties, defects, self-assembly properties, designed to accomplish specific functions and uses.
