This special issue of the Advanced Materials Research Journal, named "Nanomaterials for Structural, Functional and Biomedical Applications", contains extended versions of selected papers presented at the Forum and is devoted to the three mentioned main topics covered at the conference.
The first chapter includes articles describing research results of influence of nanostructured additions on properties of boron carbide ceramics produced by spark plasma sintering (SPS), leaded tin bronze, welding bead, cast iron, flame retardant; original techniques for synthesis and modification of silver, gold, alumina, nanoparticles, luminophores; novel approaches for development of catalysts, ultrahigh molecular weight polyethylene and polypropylene, foam glass materials.
The papers in the second chapter present developments of novel processing techniques using electron, ion beams (as well as combined electron-ion-plasma treatment), powerful ultrasound, magnetic field, stir welding, self-propagating high-temperature synthesis, magnetron sputtering, electrical explosion of wires for synthesis and/or improving properties of a number kind of materials: ceramics, alloys, steel, hard metals, thin films, magnetic particles, nanopowders.

About 8 years ago, the author co-wrote a paper with Professor Diran Apelian for the International Cast Metals Journal (IJMC) [4] which described various pressure-assisted casting processes then being used to make high integrity structural aluminum castings.
Processes suitable for mass production of a light-weight and high integrity aluminum product were presented in the International Cast Metals Journal (IJMC) reference [4] and will not be detailed again herein.
The most efficient use of a ceramic like Super Sialon might be as the lining for a high-heat resistant steel feature; 4-5 mm ceramic thickness might be adequate.
THIS CONCEPT OBVIOUSLY REQUIRES CAREFUL SYSTEMS ENGINEERING AND CONSTRUCTION, BUT ONCE THE SYSTEM IS IN PLACE IT SHOULD PRODUCE RHEOCAST PRODUCTS COMPETITIVE WITH CONVENTIONAL HPDC IN TERMS OF COST BUT WITH QUALITY AND PROPERTIES FAR SUPERIOR TO CONVENTIONALL HPDC.
