... direct metal laser melting(DMLM), the latest technology for 3D printing and additive manufacturing of metal parts.... Utilizing the DMLM process, metal parts of the most complex geometries are built layer-by-layer(down to 20 microns) directly from 3D CAD [computer-aided design] data. Parts built using DMLM have excellent mechanical properties equivalent to wrought materials, high detail resolution, and exceptional surface quality. The metal powder is melted entirely to create a fully dense, fine, homogenous structure. Unique geometric freedom of design enables DMLM to form cavities and undercuts, which with conventional machining methods, can only be produced with great difficulty, if at all. 3, record 2, English, - direct%20metal%20laser%20melting

Chelation(from Greek, chelè, meaning claw) is the process of reversible binding(complexation) of a ligand-the chelant, chelator, chelating agent, sequestering agent, or complexing agent-to a metal ion, forming a metal complex, the chelate. The term is generally reserved for complexes in which the metal ion is bound to two or more atoms of the chelating agent, although the bonds may be any combination of coordination or ionic bonds. 4, record 12, English, - demineralising%20agent

Organometallic complex catalysts tend to be highly active, specific, and selective, and may resist poisoning better than heterogeneous systems. The catalytic center may have two metal sites. Organometallic catalysts have a central transition-metal atom or ion bonded to molecules known as ligands which form a polyhedron around the metal. The nature of the metal and ligands critically influences the electronic structure of the complex. The coordination bonding properties of the metal are a key feature of the catalytic complexes. Important reactions of catalyst complexes are ligand exchange, oxidative addition, and the insertion reaction. 1, record 26, English, - organometallic%20catalyst
