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.
Nanotechnology Applications. Nanotechnology involves the understanding, manipulation, and control of matter at dimensions of roughly 1 to 100 nanometers. Nanotechnology encompasses science, engineering and technology and involves imaging, measuring, modeling, and manipulating matter at the nanoscale.anotechnology Applications.
