Products of nanotechnology are expected to revolutionize
modern medicine, as evidenced by recent scientific advances
and global initiatives to support nanotechnology and nanomedicine
research. The field of drug delivery is a direct beneficiary
of these advancements. Due to their versatility in
targeting tissues, accessing deep molecular targets, and controlling
drug release, nanoparticles are helping address challenges
to face the delivery of modern, as well as conventional
Much new material has been added to this second edition. Besides a totally new
chapter on radionuclides, the text has been reorganized and updated with separate
chapters on metals, light nonaqueous phase liquids (LNAPLs), dense nonaqueous
phase liquids (DNAPLs), and biodegradation. Also, some end-of-chapter exercises
have been added. The dictionary of inorganic pollutants has been enlarged and
some important organic pollutants added.
Conventional electrostatic capacitors contain a dielectric instead of an electrolyte solution. Electrochemical supercapacitors, however, contain a liquid electrolyte (aqueous, nonaqueous), and can be classiﬁed by the electrode material used (carbon, metal oxide, polymer) and the operating principle (double-layer capacitance, redox pseudocapacitance, hybrid capacitance).
